One hundred patients with symmetrical proliferative diabetic retinopathy had one eye randomly chosen for treatment with xenonarc photocoagulation while the other was left untreated as a control. Patients were subdivided into those with new vessels on both optic discs and those with only peripheral new vessels. In patients with new vessels on the optic discs the vision of the untreated eyes dete...

PURPOSE The incidence of retinal detachment in Blacks is generally considered to be low though there are few supporting studies in Africa. This study, thus, aimed at describing the clinical profile of patients with retinal detachment in Southwest Ethiopia. METHODS A hospital-based study was done on all consecutive retinal detachment patients who presented to Jimma University Hospital over six...

PURPOSE A zone of overlap along the vertical retinal meridian where ipsi- and contralaterally projecting ganglion cells intermingle has been demonstrated histologically in nonhuman primates. The widening of the zone of overlap in the foveal region was thought to produce a foveal sparing extending 1.5 degrees in the blind hemifield in human hemianopia. The functional relevance of the nasotempora...

AIMS To determine the ability of cyclodiode laser treatment to relieve discomfort in painful blind glaucomatous eyes. METHODS 30 eyes underwent cyclodiode to reduce intraocular pressure (IOP) and relieve pain. Patients graded their pre-cyclodiode and post-cyclodiode pain. RESULTS After a minimum follow up of 6 months, a single cyclodiode treatment lowered mean IOP from 51 mm Hg (95% CI plus...

IN a previous communication (Cullen and Butler, 1963), the ocular abnormalities encountered in a survey of 143 mongoloids at the Rosewood State Hospital in Maryland were enumerated, and particular attention was drawn to the occurrence of keratoconus in over 5 per cent. of these patients. The purpose of this paper is to elaborate the incidence and causes of blindness in this same group. In the e...

Direction of gaze (eye angle + head angle) has been shown to be important for representing space for action, implying a crucial role of vision for spatial updating. However, blind people have no access to vision yet are able to perform goal-directed actions successfully. Here, we investigated the role of visual experience for localizing and updating targets as a function of intervening gaze shi...

INTRODUCTION Glaucoma is the second leading cause of blindness worldwide. OBJECTIVE To estimate the prevalence and risk factors of glaucoma and modes of therapeutical intervention in a rural population of a developing country. PATIENTS AND METHODS A single centre-based cross-sectional study was carried out over a seven-month period in Sagarmatha Choudhary Eye Hospital (SCEH), Lahan/NEPAL, i...
