The clinical and histological features of congenital hereditary corneal oedema in 23 patients are presented. The series includes cases of both recessive and dominant inheritance. Although the condition is present at birth or in early childhood, visual development appears to be little impaired, if at all. Penetrating keratoplasty carries a relatively good surgical prognosis and can produce a sub...
Background and Objective: Keratoconus is a disorder in cornea characterized by constant thinning and prominence that can result in vision defect. Due to ultrasonic changes in the corneal structure caused by keratoconus disease, its rigidity and biomechanical properties are subject to some changes. In this regard, the present study was conducted to determine the correlation of biomechanical feat...
Congenital insensitivity to pain or more scientifically Hereditary sensory and autonomic neuropathies (HSAN) is a rare genetic disorder which associates dysfunction with varying degree of dysfunction. Due the peripheral neuropathy, decreased sensitivity even complete anesthesia may be present resulting in, on ophthalmological level, neurotrophic ulcers. We report case 2 sisters (JM KM) presenti...
PURPOSE To review the recent literature and describe the authors' experience with congenital upper eyelid coloboma. METHODS In this review, we will summarize the embryologic and etiopathogenetic bases of congenital upper eyelid coloboma, and study the published clinical reports. We will also attempt to briefly shed some light on the rarer syndromic curiosities associated with upper eyelid col...
Fuchs endothelial corneal dystrophy (FECD) is characterized by pleomorphic, attenuated, dysfunctional, and degenerated corneal endothel ium together with progressive formation of corneal guttae. The condition may show familial clustering but is usually sporadic and predominantly affects women. Family based studies have mapped late onset FECD susceptibility to 13ptel-13q12.13 and 18q21.2-q21.32....
purpose : we describe our experience on safety and effectiveness of phacoemulsification in cataract and congenital iris coloboma and point out some specific surgical recommendations aimed to minimize its complications. methods : a prospective case series study was conducted on nineteen consecutive patients with cataract and congenital iris coloboma referred to the farabi eye hospital in tehran....
purpose: to evaluate the outcomes and complications of phacoemulsification and posterior chamber intraocular lens implantation (pe+pciol) in patients with congenital iris coloboma. methods: in a prospective noncomparative interventional case series, 13 eyes of 9 patients (six female and three male) with congenital iris coloboma and cataract underwent pe+pciol using clear corneal incision and in...
The endothelial (posterior) corneal dystrophies, which result from primary endothelial dysfunction, include Fuchs endothelial corneal dystrophy (FECD), posterior polymorphous corneal dystrophy (PPCD) and congenital hereditary endothelial dystrophy (CHED). Mutations in SLC4A11 gene have been recently identified in patients with recessive CHED (CHED2). In this study, we show that heterozygous mut...
