Qualitative assessment of undetectable melanin distribution in lightly pigmented irides.
A longstanding issue in biomedical research concerns the biophysical factors affecting the color diversity of the human irides and its connection with ocular diseases. Although the pigmentation and morphological characteristics of heavily and moderately pigmented irides have been extensively discussed in the literature, similar studies are scarce for lightly pigmented irides.

متن کاملSequential argon-YAG laser iridotomies in dark irides.
Laser iridotomies in dark coloured irides are associated with higher complication and failure rates. A prospective clinical study to evaluate the use of the argon and Nd:YAG laser in sequential combination for iridotomy was carried out on 20 eyes of 13 patients with dark irides. Patent iridotomies were achieved in single treatment sessions for all the eyes. Iridotomy closure was observed in one...
متن کاملBilateral retinal vein occlusion and rubeosis irides: lessons to learn.
Uncontrolled hypertension is well- known to give rise to systemic complications involving multiple central organs. Artherosclerosis leads to damage of the retinal vessels wall, contributing to venous stasis, thrombosis and finally, occlusion. Retinal vein occlusions compromise vision through development of ischaemic maculopathy, macular oedema, and rubeotic glaucoma. Laser photocoagulation rema...
