Retinal vein occlusions are important causes of loss of vision; indeed, they are the second most common retinal vascular disease, following diabetic retinopathy. For this reason alone, primary eye-care providers must be well versed in diagnosis and management. Risk factors, though not universally agreed upon, include but are not limited to advancing age, systemic hypertension, arteriolarscleros...
For diagnosing radiation optic neuropathy (RON) ophthalmological and imaging data were evaluated from 63 acromegalic patients, irradiated between 1967 and 1998. Two patients developed RON: one patient in one optic nerve 10 years and another patient in both optic nerves 5 months after radiation therapy. RON is a rare complication after external beam radiation therapy for acromegaly, which can oc...
BACKGROUND Central retinal vein occlusion (CRVO) is a common disease characterized by a disrupted retinal blood supply and a high risk of subsequent vision loss due to retinal edema and neovascular disease. This study was designed to assess the concentrations of selected signaling proteins in the vitreous and blood of patients with ischemic CRVO. METHODS Vitreous and blood samples were collec...
purpose: to evaluate the role of transvitreal optic neurotomy (ton) in the management of non-arteritic anterior ischemic optic neurotomy (naion). methods: sixteen eyes of 16 patients with recent onset naion (less than six weeks duration) were included in this single-masked randomized controlled trial. the patients were randomized to ton (8 eyes) versus observation alone (8 eyes). pre- and posto...
