Pellucid marginal degeneration (PMD) is a rare progressive condition resulting in inferior corneal thinning and astigmatism. Alongside keratoconus and keratoglobus, it is considered one of noninflammatory corneal ectasias. The focus of corneal thinning is greatest inferiorly resulting in diminished visual acuity and overall reduction in visual quality. Traditional methods of treatment or diseas...

Method Secretion of both proinflammatory cytokine interleukin (IL)-1α and tumor necrosis factor (TNF)-α was measured after cultivation of 47 corneas collected from corneal graft recipients suffering from different corneal diseases. Non-inflammatory corneal diseases were keratoconus (n = 8), keratoglobus (n = 2), bullous keratopathy (n = 11), and Groenouw stromal dystrophy type II (n = 2), where...

AIM To determine the normative values of white-to-white corneal diameter with Orbscan II Topography System and to compare right and left eyes data in the normal young population. METHODS A total of 1001 healthy participants aged 18-45y participated in this observational cross-sectional study. The study population consisted of 616 female and 385 male subjects. The corneal diameter was measured...

The Hallermann-Streiff syndrome is a complex association of developmental anomalies principally involving structures of ectodermal origin. The constant expressions of the syndrome are dyscephaly with mandibulo-facial malformation, bilateral congenital cataracts, and dental anomalies, while hypotrichosis, cutaneous atrophy, microphthalmos, and proportionate dwarfism are frequently present (Table...

TBE classification of the heredo-familial degenerations of the cornea proposed by Franceschetti and Fomi (1950) and Franceschetti (1954), includes among the degenerations of the anterior limiting membrane (Bowman's) a rather rare manifestation called "mosaic degeneration". Because of its rarity, and because of certain unusual features, we have considered it worth while to report three cases rec...

A 4-year-old girl was referred to the department of ophthalmology of the Rothschild Hospital, Haifa, because of a blue discoloration of the sclerae from birth, bulging of the eyes which had been first noticed at the age of4 months, and apparent short sight. The child was the product of a normal pregnancy and a normal full-term delivery. The birth weight was 3-6 kg. There had been three episodes...

We received approval from the U.S. implant Food and Drug Administration and the University's Institutional Review Board to the Artisan lens (Ophtec BV) in both eyes of a patient who was aphakic and had megalocornea. No other intraocular lens would easily solve this patient's need because of the large anterior segment. The patient was having increasing difficulty with aphakic contact lenses beca...
