... 7 Corneal abnormalities like corneal opacity and edema are some of the atypical features of ARS caused by glaucoma or intraocular surgery in most cases. 8 The ARS can include other complications like craniofacial deformities such as, maxillary hypoplasia, hypertelorism, telecanthus, enlarged sella turcica, and sometimes, cleft palate along with dental and periumbilical abnormalities. 9,10 The key dental features include maxillary hypodontia or oligodontia, microdontia, enamel hypoplasia, taurodontism, conical teeth, short roots, and delay in eruption. ...

... The procedure of choice remains the implantation of drainage devices. Keywords: anterior segment dysgenesis, congenital corneal staphyloma, penetrating keratoplasty, glaucoma, drainage surgery _________________________________________________________________________________________________  ВВЕДЕНИЕ Врожденная стафилома роговицы, или врожденная передняя стафилома, -редкая аномалия развития, характеризующаяся увеличенной в диаметре непрозрачной эктазированной роговицей, выступающей через межпальпебральную щель, в сочетании с выраженным дисгенезом переднего сегмента глазного яблока [1][2][3][4][5]. ...

... HSV-1 seroprevalence among adult non-Hispanic white females and males in the U.S. midwest is less than that in other regions of the U.S. and has decreased in recent years [11]. Third, donor corneal Descemet membrane and endothelium layers used in DMEK have been linked to HSV transmission [9,12,13], and HSV DNA has been detected in pretransplant donor corneas given to DMEK recipients who then developed HSV infection causing graft detachment and corneal edema [9,12,13]. Lastly, our patient's corneal HSV infection was limited to the DMEK graft area at the inner corneal surface where it produced anterior chamber inflammation but not retinitis. ...

... Moreover, pseudopterygium could be caused by a chronic inflammatory process [33][34][35][36] such as chronic cicatrizing conjunctivitis [37][38][39], after an ocular infection due to ocular gonorrhoeae [36], herpesviridae [37], or pseudomonas [38]; due to autoimmune processes such as mucous membrane pemphigoid [12,[39][40][41][42][43][44], epidermolysis bullosa [13,45], erythema multiforme [12], ocular rosacea [35,46], Still disease [18], ocular atopy [11,47], actinic prurigo [48][49][50][51][52][53], ocular psoriasis [54], or erythema elevatum diutinum [55]; and even related to ocular topical drugs [56]. Other less frequent causes with which it has been related would be Goldenhar-Gorlin syndrome [57], xeroderma pigmentosum [58], ocular keloids [59,60] and in conjunctival lymphangiectasia [61] (Figure 3). ...

... In the study conducted by Yang et al., the mean preoperative visual acuity for the CHED group was 1.03 ± 0.25 logMAR, which was better than that observed in our study group. [22] In comparison to reported studies wherein the visual acuities seen in PA and PCG groups were 2.049 ± 0.965 and 0.37 ± 0.48 logMAR, respectively, the visual acuities were decreased in our study groups. [23,24] A higher mean and median IOP was seen in the PCG group as compared to the CHED and PA groups though not statistically significant. ...

... They compared the two devices and reported that SimK (5mm) zone measurement was more reliable in IOL power calculation and gave the lowest MAE value. The only study in the literature about IOL power calculation in corneas that had undergone keratoplasty was performed by Xu et al. [22]. They compared different K readings in pseudophakic patients post-Descemet's stripping automated endothelial keratoplasty (DSAEK) and evaluated corresponding prediction errors in IOL power calculations. ...

... Only 1 (0.6%) case was diagnosed with FK. 33 Neovascularization also becomes a risk factor for VK or outcome after VK. Similar findings that neovascularization was a significant sign of the development stage and convalescence stage were observed in AK. 34 Gurung et al. 35 pointed out recurrent HSV stromal keratitis was associated with neovascularization and a well-defined factor (fibroblast growth factor-2) could drive and maintain progressive corneal neovascularization after HSV-1 infection. As another major portion of the non-FK group, BK always presented an acute onset pattern that VEGF-A would rapidly increase in the early stages of disease (Day 2) and promoted corneal angiogenesis. ...
