The records of 57 patients with recent central retinal vein occlusion were reviewed in order to predict the development of rubeosis iridis (RI) and neovascular glaucoma (NVG) from the initial clinical examination, colour fundus photographs, and fluorescein angiograms. Twelve patients (21 %) developed both RI and NVG, and this complication appeared to be correlated most significantly with clinic...

PURPOSE To investigate the effect of naturally occurring and synthetic peroxides on norepinephrine release from isolated iris-ciliary bodies of several mammalian species. METHODS Hemiirides (bovine) and iris-ciliary bodies (human, rabbit, and rat) were incubated in Krebs solution containing [3H]-norepinephrine ([3H]NE) for 60 minutes. After incubation, tissues were set up for studies of [3H]N...

BACKGROUND The aim was to determine whether latitudinal (Queensland versus Tasmania) variation in reported disease frequency in Australia may be biased by differences in population. METHODS A retrospective analysis was conducted from data of two large Australian twin studies (n = 1,835) having undertaken ophthalmic examination, namely, Twins Eye Study in Tasmania (TEST) and the Brisbane Adole...

Both eyes were free of inflammation and the irides were of the blue type with scattered honey-coloured freckles. The right eye showed a pale yellow spherical mass approximately 2 mm. in diameter within the iris stroma almost midway between the pupil margin and the root of the riris in the upper temporal sector (Fig. I). Large curly new vessels coursed in the iris stroma from the periphery radia...

Human corneas and irides obtained from corneal surgery or sector iridectomies were processed according to the indirect immunofluorescence technique for the demonstration of substance P (SP) immunofluorescence by means of a monoclonal SP antibody. SP immunofluorescence was observed in varicose fibers of the corneal epithelium and nerve trunks in the corneal stroma. SP-immunoreactive nerve fibers...

A total of 125 consecutive eyes, all registered blind with diabetic vitreous haemorrhage, underwent pars plana vitrectomy with the vitrophage. Sixty-six per cent experienced some improvement in their visual acuity; 24 per cent were unchanged and 10 per cent were worse postoperatively. The major surgical complication was controllable haemorrhage (23 per cent). No retinal dialysis occurred. Signi...

Existing researchers for rubeosis iridis disease focused on image enhancement as a collective group without considering the multi-contrast of images. In this paper, pre-enhancement process was proposed to improve quality iris images by separating into three groups; low, medium and high contrast. Increment, decrement maintenance images’ original contrast were further operated noise reduction man...

PURPOSE To determine the effect of diabetes mellitus on the levels of substance P (SP), calcitonin gene-related peptide (CGRP), and vasoactive intestinal polypeptide (VIP) in the rat cornea and iris. METHODS Corneas and irides from control and diabetic rats were processed for neuropeptide radioimmunoassay 3 months after induction of diabetes with streptozotocin. Corneas and irides also were p...
