Evaluating macular and optic nerve changes during Ramadan fasting by optical coherence tomography angiography-a prospective before-and-after study.

Purpose: During Ramadan, millions of Muslims fast from sunrise to sunset. Fasting influences the hormonal system, sympathetic activity, blood circulation, and metabolic pathways. Because of these changes, we employed optical coherence tomography angiography (OCTA) to investigate the effects of fasting on the macula and optic nerve.

Time course study of optical coherence tomography angiography in patients with methanol induced optic neuropathy.

Introduction: In countries where alcoholic beverages are legally prohibited, methanol toxicity usually occurs due to ingesting homemade alcoholic drinks. The initial ophthalmologic symptoms of methanol toxicity typically appear 6-48 h after ingestion, and the severity of symptoms varies widely from mild and painless decreased vision to no-light perception vision.

Methods: This prospective study examines 20 patients with acute methanol poisoning within 10 days of use.

Conventional and Pattern Scanning Pan-Retinal Photocoagulation Laser in Diabetic Patients' Visual Field.

In this study, we aimed to compare visual field defects in two different laser methods, namely conventional pan-retinal photocoagulation (PRP) and pattern scanning PRP, in patients with either proliferative diabetic or very severe non-proliferative diabetic retinopathy. This study was a randomized, single-blind, prospective clinical trial. Twenty patients with either proliferative or very severe non-proliferative diabetic retinopathy were enrolled in this study.

Severe Optic Disc Cupping Following the Methanol Toxicity in a 20-Year-old Man: A Case Report.

In April 2018, a 20-year-old man with a history of methanol intoxication from an alcoholic drink two years ago, when he was 18 years old, was referred to Nikookari Eye Hospital in Tabriz, Iran. He was admitted to emergency service and underwent eight hours of hemodialysis at the time of poisoning. His past medical history was negative, and he did not take any medication after discharge.
