Ophthalmic evaluation revealed cotton wool spots on the right eye and widespread retinal necrosis and hemorrhage on the left eye, suggestive of cytomegalovirus uveitis and HIV infection and retinopathy, and confirmed by serology. The patient was treated with ganciclovir and highly active antiretroviral therapy and preserved contralateral vision. Clinicians should be aware of uveitis and retinopathies to prevent irreversible vision loss […]

Acute zonal occult outer retinopathy (AZOOR) is a rare disease characterized by an acute damage of one or more external retinal zones leading to the visual field or the visual acuity impairment associated with small or no changes in the fundus examination.The main clinical symptoms are scotomas and the sudden onset of photopsias. Abnormal findings on electroretinography and visual field defects are critical for the diagnosis. Central vision is usually preserved and the stabilization occurs in six months in most […]

Objective: To compare the effectiveness of metamizole versus ibuprofen for the reduction of pain in retinal photocoagulation (RP). Method: A double-masked randomized controlled study was performed. Thirty-four patients with diabetic retinopathy were enrolled. The patients were randomized into two groups. Group A received oral 1000 mg metamizole. Group B received an oral intake of 600 mg ibuprofen. Pain during RP was assessed using a visual analog scale. Results: The mean pain scores for groups A and B were 5.2±2.6 and […]
