THE term microcornea should be reserved for the condition wherein an abnormally small cornea (diameter less than 11 mm.) occurs in an otherwise relatively normal eye (Mann, 1957). Friede (1922) suggested the term "anterior microphthalmos", because the whole of the anterior segment of the eye seems to be small. The rectus muscles are inserted abnormally far forwards, and the corneal curvature te...
Purpose We compared the anterior segment characteristics of congenital cataract (CC) patients with lens opacities in different locations and proposed a modified, simple CC category system. Methods Cataractous eyes of CC patients were classified into four groups based on the locations of lens opacities shown in slit-lamp examinations and by a 3-dimensional anterior segment imaging system as fo...
Report keratoconus in two patients with a long history of wrestling without any risk factor for corneal ectasia and reviewing the possible pathogenesis. To confirm suspicion of keratoconus, corneal topography was performed using scanning slit topography system and Orbscan. In two wrestlers with the complaint of visual loss in their eyes and IOP raising, corneal topography was performed and de...
CONGENITAL corneal opacities vary greatly in extent and location and are usually associated with other anomalies of the anterior segment. Although a variety of clinical terms, such as cornea plana, sclerocornea, Rieger's anomaly, Axenfeld's syndrome, has been used to describe these anomalies, recent evidence (Goldstein and Cogan, 1962) suggests that they are all closely related entities. Theodo...
AIM This is a report of the incidence of bilateral cases in a cohort of primary congenital glaucoma (PCG) cases and a study of the biometric characteristics of the fellow normal eyes in unilateral cases. MATERIALS AND METHODS The charts of 134 PCG children were reviewed, of which 78 cases (58.2%) were found to have bilateral disease. The remaining 56 patients (41.8%) with unilateral disease h...
PURPOSE The purposes of this study are first, to determine if the palisades of Vogt (POV) are present or absent in cases of congenital corneal opacification (CCO) by using spectral domain ocular coherence tomography (SD-OCT), and second, in those cases already undergoing penetrating keratoplasty (PKP), to see whether the absence or presence of POV corresponds to re-epithelialization following t...
Background and purpose: Astigmatism is a common optical dysfunction, effective on various visual outcomes and one of the important criteria of refractive surgery. The aim of present study was to evaluate the correlation between refractive, corneal and residual astigmatism in refractive surgery candidates. Materials and methods: In this cross-sectional descriptive, analytical study, 200 patient...
