Abstract and Figures

Aripiprazole is a drug belonging to the group of atypical antipsychotics. Ocular side effects of aripiprazole are rare. We report a case of transient myopia in a 33-year-old male who was being treated for schizophrenia with oral quetiapine and was recently supplemented with aripiprazole. One month after the addition of aripiprazole the patient reported sudden onset painless blurring of vision in both eyes. He was found to have myopia of-3.0 diopters in both eyes; his corrected visual acuity being 20/20. He was advised to discontinue aripiprazole. Ten days later on examination, the patient had an uncorrected visual acuity of 20/20 in both eyes. The stoppage of symptoms on stopping the drug indicates a strong correlation between the drug and the adverse effect. Ophthalmologists and psychiatrists must be aware of this reversible adverse drug reaction, so it may be treated promptly.

Introduction
Aripiprazole is a new drug belonging to a class of
atypical antipsychotics. It is a quinolinone derivative
with a high affinity for dopamine D2 and D3 receptors,
and serotonin 5-HT1A, 5-HT2A and 5-HT2B receptors
(1). It is used in the treatment of schizophrenia and
schizoaffective disorders, treatment resistant depres-
sion, bipolar disorder and obsessive-compulsive
disorder (2).
Commonly reported side eects include somnolence,
headache anxiety, insomnia, nausea, and vomiting (2).
Other less frequently reported side eects include par-
oxysmal supraventricular tachycardia, Pisa syndrome,
hiccups and rabbit syndrome (3). Out of 926 subjects
who received oral arpiprazole in short-term, placebo-
controlled trials, 3 subjects reported blurred vision. e
exact cause and nature of this visual complaint, however,
was not mentioned (4). Documented ocular side eects
of arpiprazole are rare. ere have been, to the best of
our knowledge, only 2 other cases of arpiprazole induced
transient myopia
Case history
We wish to report a case of acute transient myopia
caused by the use of arpiprazole. A 33-year-old male
patient reported to our hospital with a complaint of sud-
den painless blurring of vision in both eyes. ere was
no other ocular complaint and he had no prior history
of using glasses. His uncorrected visual acuity was 20/80
in both eyes. His best-corrected visual acuity was 20/20
in both eyes with a refractive error of−3.00 diopters.
Pupillary evaluation was normal with no aerent pupil-
lary defect. Ocular motility was normal in both eyes. Slit
lamp examination revealed shallow anterior chamber
depth. Gonioscopic examination showed the angles to
be moderately narrow: 20° (Grade II− Shaer’s classi-
cation) with a convex iris conguation. ere was no
evidence of pupillary block. Dilated fundus examination
was normal in both eyes. Intraocular pressure in both
eyes was 14 mm Hg. Systemically; the patient was not
a hypertensive or a diabetic and did not have a history
of substance abuse. He had, however been diagnosed
with schizophrenia and was being treated with tablet

quetiapine fumarate (Psynil, Crescent erapeutics,
Hyderabad, India) which had been titrated to daily
25 mg dose over three years. He was subsequently sup-
plemented with a daily dosing of 15 mg of arpiprazole
(Arpit, Crescent erapeutics, Hyderabad, India), 30
days prior to the onset of the ocular symptoms. Given
the clinical history, the normal intraocular pressures
and the open angles on gonioscopy, there was a high
degree of suspicion that the myopic shift was drug
induced. e patient was therefore not investigated. A
psychiatric referral was sought and subsequently oral
arpiprazole was stopped with the patient being under
close follow-up. e patient was re-examined 10 days
later and was found to have an uncorrected visual acu-
ity of 20/20. e anterior chamber was of normal depth
and the intraocular pressures were 14 mm Hg in both
eyes. Gonioscopy of both eyes showed the angles to be
widely open: 45° (grade IV) Dilated funduscopy was
normal.
Discussion
Acute, transient myopia may be caused by many drugs
(Table 1). e various mechanisms of drug-induced
myopia reported in literature are accommodation
spasm, ciliary body eusion, the eect of ocular sero-
tonergic, interneuronal bers, ciliary spasm, increase
in thickness of the lens and peripheral uveal eusion
(3,5). Ciliary body rotation and edema resulting in
forward movement of iris lens diaphragm has been
reported as another possiblility leading to acute myo-
pia (6).
Selvi et al. described a case of a 19-year-old female
who was treated with oral arpiprazole for obsessive-com-
pulsive symptoms (3). Fifteen days after the initiation
of 10 mg daily dose of aripiprazole therapy, the patient
developed myopia and diplopia, which resolved when
aripiprazole was stopped. Our case had no complaints of
diplopia. Kaya et al. have reported a case of a 21-year-old
female, diagnosed to have bipolar aective disorder on
sodium valproate (5). Oral aripiprazole 15 mg was added
when she presented with manic symptoms. Seven days
after the introduction of aripiprazole, she developed
myopia in both eyes, which disappeared 10 days after
stopping the drug (Table 2). It is also interesting to note
that the duration between the initiation of oral aripipra-
zole and the ocular symptoms in our case was substan-
tially longer than the other two case reports (30 days vs.
7 and 15 days).
We report this case of transient myopia, attributable
to the use of aripiprazole. e resolution of symptoms
on discontinuing the drug points to a strong co-relation
between the symptoms and the medication. Adverse
drug reactions such as sudden onset, transient myopia
can be distressing for patients. erefore, we believe that
clinicians prescribing aripiprazole must inform and edu-
cate the patients regarding this possible ocular adverse
eect. Ophthalmologists must be aware of this ocular
adverse eect, which may occur well after therapy is initi-
ated; promptly recognize it and stop the drug in order to
reverse the symptoms.

Central serous chorioretinopathy (CSCR) is a chorioretinal disease that is characterized by central vision loss and is usually seen in middle-aged males. It has been associated with the use of various drugs, including corticosteroids and phosphodiesterase inhibitors. We present the case of a 36-year-old male who developed CSCR after a few weeks of irregular use of quetiapine for his sleep problems. The clinical findings of the patient improved shortly after he stopped using the drug, and at the end of the two-month period complete recovery was observed. Quetiapine is an atypical antipsychotic that exerts its effects on dopamine and serotonin receptors. There are studies showing that these neurotransmitters may play a role in the control of choroidal vascular permeability, which is the underlying cause of CSCR. Therefore, we believe that quetiapine may have a causal relationship with CSCR. To our knowledge, this is the first case report documenting full recovery from quetiapine associated CSCR.

Antipsychotics are widely used in psychiatric practice for treating schizophrenia, bipolar disorder, and other diseases, including those treated off-label. They manifest many adverse effects, including ophthalmic ones. Some of these effects, such as persistent mydriasis, cycloplegia, extraocular muscle dystonia, and visual hypersensitivity attacks are reversible, since they disappear after dose reduction or drug withdrawal. Yet other side effects, such as cataracts, corneal edema, acute angle closure glaucoma and retinopathy are threatening for sight and may lead to permanent visual acuity decline and even blindness. The review provides data on the incidence of ocular side effects (both typical and atypical) of multiple antipsychotics, their clinical manifestations, pathogenesis and treatment. Eye examination is recommended for patients taking antipsychotics in the early periods of treatment and then twice a year. The psychiatrists need to know about the adverse effects of individual drugs whilst the ophthalmologists should be aware of their semiotics, pathogenesis and treatment, since timely diagnosis and treatment of pathological changes, together with antipsychotic therapy modification, prevent the development of severe and irreversible visual impairment in the majority of cases.

The study of high axial myopia in the setting of antecedent, concurrent or subsequent ocular disorders, systemic diseases, hereditary syndromes, and systemic drug use may contribute to our understanding of the pathogenesis of myopia and even set the occasion for the development of treatment. Although early recognition of mild myopic changes that commonly arise with certain ocular and systemic factors may limit the burden of vision loss with simple refractive correction, the recognition of high and pathologic axial myopia is important since there is a risk of permanent vision loss from vision-threatening sequelae. Therefore, the study of cases of high axial myopia, and specifically those cases in which there may be a causal relationship, is of particular interest. Additionally, recognition of the tendency of some syndromes to be associated with high myopia heightens the clinical suspicion for detection of severe refractive errors in patients who maybe preverbal or unable to effectively communicate. Clinical studies and basic scientific discoveries oftentimes mirror and motivate each other. In this chapter, we detail clinical observations and studies that have been proven, or may in the future prove themselves, relevant to current thoughts on emmetropization and animal models of myopia discussed more thoroughly elsewhere in this book.
Chapter
This book is intended as a guide to help the clinician determine where a visual problem is a drug-induced ocular side effect. We continually review spontaneous case reports from the National Registry of Drug-Induced Ocular Side Effects, the World Health Organization, the US Food and Drug Administration, and the world literature. We have attempted to classify a suspected adverse event with our impression to causality (i.e. certain, probable, unlikely, conditional/unclassified). This chapter discusses drugs affecting the central nervous system including analeptics, anorexiants, antianxiety drugs, anticonvulsants, antidepressants, anti–multiple sclerosis drugs, antipsychotic drugs, depressants, genitourinary tract drugs, psychedelic drugs, sedatives, and hypnotics.

Aripiprazole is an atypical, antipsychotic drug used for the treatment of schizophrenia, depression, bipolar disorder, and obsessive-compulsive disorder in adults. There are a few reports in the literature of ocular side effects of aripiprazole, such as transient myopia, diplopia, and acute angle closure. This report describes the case of a 34-year-old female patient who was referred to the clinic with painless blurred vision in both eyes. She had been diagnosed with major depression and had been using aripiprazole for a month. She experienced blurred vision after the first week of drug therapy. The uncorrected visual acuity (UCVA) was 4/10 in both eyes using a standard Snellen chart. She had a refractive error of -2.00 diopters and the best corrected visual acuity was 10/10 in both eyes. The ocular examination results were normal other than the refractive error. The patient was diagnosed with aripiprazole-induced, acute transient myopia. The UCVA was 10/10 in both eyes at the 2-week follow-up following termination of the aripiprazole therapy. It is important to be prepared to recognize aripiprazole-induced, acute transient myopia in patients complaining about blurred vision

This study aims to present a case of transient myopia due to aripiprazole used in the treatment of depression. A 21-year-old female who was being treated for depression with 15 mg/day Aripiprazole during two months. She normally used -3.75 D glasses. She was admitted to our outpatient clinic with sudden onset blurring of vision in both eyes despite using glasses for about three days. Using of aripiprazole was observed in the patient's history. She was found to have myopia of -6.0 diopters in both eyes with measurement of otorefractometer; her visual acuity was 6/10 in both eyes with her glasses. The other eye examination findings of the patient were normal. The drug was discontinued, and the patient was followed. One mount later on examination, the patient's visual acuity increased to 10/10 in both eyes. Following the first day of the Alx values measured were 0.3 mm longer than one month after the measurement; the minimal difference between the other anterior segment findings were recorded. Although the specific mechanisms that cause acute myopia has not been fully revealed, it can be ciliary spasm, ciliary bodies effusion, peripheral uveal effusion and effects of ocular serotonergic intraneural fibers. We believe that it would be important for clinicians. They should keep in mind these conditions when prescribing aripiprazole and need to inform patients about the side effects related to the eye.

A thirty year old insomniac, an off label user of quetiapine presented with blurring of central vision, eventually diagnosed as Central serous chorioretinopathy. A potential association was suspected based on the drug’s actions on the autonomic nervous system. He had an improvement on drug withdrawal; then he unwittingly resumed quetiapine and had a recurrence. Possible underlying mechanisms that include alteration in choroidal perfusion through serotonin and dopamine receptors are discussed. While retinal vein occlusions and pigment epithelial detachment have been described with quetiapine, to author’s knowledge, this is the first case report of quetiapine associated Central serous chorioretinopathy.

Aripiprazole is a new drug for the treatment of adults with schizophrenia. Ocular side effects of aripiprazole are very rare. Review of literature revealed few cases of aripiprazole-induced myopia. We report a rare case of aripiprazole-induced transient myopia. A 22-year-old female patient presented to the department of psychiatry with worsening of symptoms of schizophrenia and was started on aripiprazole. She presented with complaints of blurring of vision in both eyes for 1 week which started on the 3rd day following the use of aripiprazole. Anterior segment examination revealed a shallow anterior chamber and narrow angles. Intraocular pressure was normal. A diagnosis of aripiprazole-induced acute myopia was made and the treating psychiatrist was advised to stop the medication. At 2-week follow-up, the unaided visual acuity improved to 20/20 in both the eyes. Ophthalmologists should be aware of the myopic shift that may occur as an ocular side effect with aripiprazole.

Drug-induced secondary angle closure is quite common and in the majority of cases simply stopping the medication leads to rapid reversal of the condition and resolution of glaucoma. We describe here a patient who presented with secondary angle closure glaucoma and myopia following mefenamic acid ingestion which was managed successfully by stopping the medication, symptomatic treatment and reassurance.

Acute acquired myopia is a rare condition in psychiatry and ophthalmology practice. Several drugs have been reported, produce blurring, decrease accommodation and cause diplopia. To our knowledge there is no report of ariprazole that caused ophalthalmologic side effects. In this report we will discuss a case of aripirazole induced myopia. 21-year-old woman, with known case of bipolar affective disorder with 2 previous manic episodes in 2004 and 2006. She was under the treatment with reguler mood stabilizer sodium valproat 1000 mg/day. She presented with manic symptoms for 10 days. Aripiprazole 15 mg/day was added. The patient who had no refraction error before, reported blurring of distance vision in the seventh day of treatment. She consulted an ophthalmologist, who confirmed binocular myopia of - 7 diopters in the right eye and - 8 diopters in the left eye. Ten days after discontinuation of aripiprazole, . Her visual acuity was 20/20 without correction. Because of the disappearance of transient myopia following discontinuation of the drug we diagnosed the case as drug-induced myopia due to aripirazole. In cases with drug induced acute myopia the discussions of the mechanisms include accomodation spasm, ciliary body effusion, ciliary spasm and peripheral uveal effusion. Drug induced myopia is one of the most common causes of transient myopia. Aripiprazol is a second generation antipsychotic with a novel pharmacological profile which exhibits a partial agonistic effect on dopamin D2, D3 and serotonin 5HT1a receptors and antagonistic effect on serotonin 5HT2a receptors. This side effect due to aripiprazole, improved to normal without any intervention. The case report indicates that clinicians need to take account of the possibility that myopic shifts may be associated with new drugs.

Abstract Aripiprazole, a quinolinone derivative, is an atypical antipsychotic drug indicated for the treatment of adult patients with schizophrenia. Aripiprazole 10 or 15mg once daily is effective and well tolerated in patients with schizophrenia or schizoaffective disorder. Although aripiprazole has only been directly compared with haloperidol and olanzapine in treatment-responsive patients to date, current data generally indicate that aripiprazole has a beneficial profile in terms of a low potential for bodyweight gain. Dosage titration is not necessary and the drug is effective in the first few weeks of treatment. Head-to-head comparative trials with atypical antipsychotic agents are required, as are long-term (≥1 year) studies, to fully define the position of aripiprazole in relation to other antipsychotic drugs. Aripiprazole is a valuable new therapeutic option in the management of patients with schizophrenia. Pharmacological Properties Aripiprazole is a quinolinone derivative with a high affinity for dopamine D2 and D3 receptors, and serotonin 5-HT1a, 5-HT2A and 5-HT2B receptors. The mechanism of action of aripiprazole is not yet known, but evidence suggests that its efficacy in the treatment of the positive and negative symptoms of schizophrenia and its lower propensity for extrapyramidal symptoms (EPS) may be attributable to aripiprazole’s partial agonist activity at dopamine D2 receptors. At serotonin 5-HT1a receptors, in vitro studies have shown that aripiprazole acts as a partial agonist whereas at serotonin 5-HT2A receptors aripiprazole is an antagonist. The main active metabolite, dehydro-aripiprazole, has affinity for dopamine D2 receptors and thus has some pharmacological activity similar to that of the parent compound. Aripiprazole is rapidly absorbed after oral administration. The mean time to peak plasma concentration is 3 hours following multiple-dose administration of aripiprazole 10 or 15mg and the absolute oral bioavailability of the drug is 87%. Steady-state plasma drug concentrations are achieved by 14 days; however, the drug appears to accumulate over this period, since mean peak plasma concentration and mean area under the plasma concentration-time curve values of aripiprazole 10 or 15 mg/day are 4-fold greater on day 14 than on day 1. This accumulation may be expected, since the mean elimination half-life of a single dose of aripiprazole is about 75 hours. Aripiprazole has extensive extravascular distribution and more than 99% of aripiprazole and dehydro-aripiprazole (the main active metabolite of aripiprazole) is bound to plasma protein. Elimination of the drug is primarily hepatic; the cytochrome P450 (CYP) 3A4 and CYP2D6 enzyme systems transform aripiprazole to dehydro-aripiprazole, with the latter enzyme system subject to genetic polymorphism. Thus, dosage adjustment of aripiprazole is necessary when it is coadministered with CYP3A4 and CYP2D6 inhibitors (since aripiprazole concentration is increased) and with inducers of CYP3A4 (since aripiprazole concentration is decreased). Therapeutic Efficacy The efficacy of aripiprazole has been demonstrated in patients with schizophrenia or schizoaffective disorder. In general, significant reductions from baseline in mean Positive and Negative Syndrome Scale total, positive and negative symptom scores, and Clinical Global Impression Severity of Illness scores were observed in patients with acute relapse of chronic schizophrenia or schizoaffective disorder receiving recommended (10 or 15 mg/day) or higher-than-recommended (20 or 30 mg/day) dosages of aripiprazole versus those receiving placebo in three well controlled, short-term trials. No additional therapeutic benefit was observed at the higher-than-recommended dosages. The drug is effective as early as the first or second week of treatment. The efficacy of aripiprazole was maintained for up to 52 weeks. The drug was significantly more effective than placebo in preventing relapse in patients with stable chronic schizophrenia in a 26-week, randomised trial. In a 52-week trial in patients with acute relapse of schizophrenia, the percentage of responders maintaining a response at study end was 77% of aripiprazole versus 73% of haloperidol recipients. Aripiprazole may improve cognitive function. In a nonblind, 26-week trial, patients with chronic schizophrenia receiving aripiprazole 30 mg/day experienced similar (general cognitive function) or better (verbal learning) changes from baseline in the neurocognitive parameters evaluated compared with recipients of olanzapine 10–15 mg/day. Tolerability Aripiprazole 10–30 mg/day was generally well tolerated. The tolerability profile of aripiprazole was broadly similar to that observed with placebo in a meta-analysis of short-term trials in patients with acute relapse of schizophrenia or schizoaffective disorder and in a 26-week trial in patients with chronic stable schizophrenia. The most frequent treatment-emergent adverse events included insomnia and anxiety, and additionally, headache and agitation (in short-term trials) or akathisia and psychosis (in a 52-week trial). In general, the drug was associated with a placebo-level incidence of EPS and EPS-related adverse events. Significantly fewer aripiprazole recipients experienced EPS-related adverse events than haloperidol recipients in a 52-week trial. Changes in severity of EPS were minimal and usually no different from those observed with placebo. Moreover, there was less severe EPS in the aripiprazole group than the haloperidol group in a long-term trial. Treatment-emergent tardive dyskinesia was reported in only 0.2% of patients receiving aripiprazole (short-term trials), an incidence similar to that seen in placebo recipients (0.2%). Aripiprazole has a low propensity to cause clinically significant bodyweight gain, hyperprolactinaemia or corrected QT interval prolongation in patients with schizophrenia or schizoaffective disorder. In addition, there were no clinically relevant differences in mean changes from baseline in measures of diabetes and dyslipidaemia between the aripiprazole or placebo groups in a 26-week, placebo-controlled trial.

We present three cases of women who developed acute transient myopia caused by drugs for gynecological problems. One patient was treated with disothiazide for premenstrual edema. The second had acute cystitis and was treated by sulphonamide and the third developed myopia coincident with metronidazole treatment for trichomonas vaginalis. We followed these patients by A scan ultrasonographic ocular measurements, documenting reduction of the anterior chamber depth combined with lens thickening. The ocular and myopic changes cleared up completely on discontinuation of the causative agent. The possible mechanism is thought to be an allergic reaction to the drug.

We treated a case of transient myopia in a patient being treated with hydrochlorothiazide and triamterene for tinnitus. The patient underwent gonioscopic, ophthalmoscopic, and echographic examinations. Examination showed anterior chamber flattening and echography disclosed bilateral 360-degree shallow choroidal detachments.

Drug-induced oedema of the ciliary body is rare, and occurs predominantly following exposure to sulphonamides. In a 31-year-old patient in her 37th week of pregnancy, we observed reversible myopia of -4.75 dioptres following the ingestion of chlorthalidone. In a second case report we describe, in a 61-year-old patient suffering from aspirin-sensitive asthma, recurrent ciliary body oedema with a marked spastic component which was triggered by the medications acetazolamide, dipivefrine and pilocarpine. We explain oedema of the ciliary body on the basis of the eicosanoids. We believe that the oedema is caused mainly by prostaglandins and that leucotrienes are predominantly responsible for the spastic component. We postulate a drug-induced elevation in eicosanoid concentrations, as well as certain interrelationships between ciliary body oedema and aspirin-sensitive asthma.
