UNLABELLED The use of ocular prostheses for ophthalmic patients aims to rebuild facial aesthetics and provide an artificial substitute to the visual organ. Natural intemperate conditions promote discoloration of artificial irides and many studies have attempted to produce irides with greater chromatic paint durability using different paint materials. OBJECTIVES The present study evaluated the...

Eight eyes with central retinal vein occlusion one eye with old central retinal artery occlusion complicated by rubeosis iridis or increased intraocular pressure, or both; and one eye with diabetic retinopathy and rubeosis iridis were treated by retinal panphotocoagulation. Vision did not improve but intraocular pressure was lower and iris neovascularisation regressed in most cases, supporting ...

AIMS/BACKGROUND Proton beam radiotherapy can effectively treat primary uveal melanomas of any size. Some patients, however, develop adverse late effects following treatment and the purpose of this study was to determine which factors give rise to a poor local outcome. METHODS The hospital records from a first cohort of 127 patients treated by protons from 1989 to 1992 were reviewed retrospect...

We present an infant with heterochromia of the irides and a motility disorder of the oesophagus. The association between Hirschsprung's disease and heterochromia of the irides has been reported in the past and has been explained by the common origin during embryogenesis of the parasympathetic ganglion cells and the stroma of the iris.

PURPOSE To determine whether the extent of disease in age-related macular degeneration (AMD) varies with iris pigmentation. METHODS The authors assessed visual function and macular appearance in the fellow eye or both eyes of 132 white patients with unilateral neovascular AMD. All patients had a visual acuity of 20/60 or better in the fellow eye. Eighty-nine of the patients were coded as havi...

Although abnormal iris vessels and secondary glaucoma in a patient with proliferative diabetic retinopathy was described over 8o years ago by Nettleship (i888), Salus (1928) was the first to call attention to rubeosis of the iris as a specific manifestation of long-term diabetes and to point out that the neovascularization of the iris resulted in haemorrhagic glaucoma. Neovascularization of the...

Central retinal vein occlusion (CRVO) with capillary non-perfusion predisposes to retinal neovascularisation and rubeosis iridis (Laatikainen and Kohner, 1976). Studies on diabetic retinopathy suggest that destroying large areas of hypoxic retina or reducing its metabolic demands prevents neovascularisation and may cause retinal vessels to regress (Taylor, 1970). It was therefore decided to try...

Neovascularization of the iris was induced in cats by removing the vitreous and lens and creating a rhegmatogenous retinal detachment. The presence of new blood vessels on the anterior surface of the iris was verified from the second month onward by slit lamp examination, as well as by light microscopy six to twelve months after the operation. Control eyes undergoing vitrectomy and lensectomy, ...
