PURPOSE To assess the significance of the components of the electrically evoked response. METHODS Twenty-three normal subjects, six patients with macular holes, and three patients with retinal artery occlusion were tested. The electrically evoked responses were recorded from an occipital electrode by applying an electric current of 0.3 mA-2.0 mA with a duration of 5 msec and a frequency of 1....

Retinal vascular lesions are the most common ophthalmologic manifestation of systemic lupus erythematosus (SLE), occurring in 3% to 29% of cases, generally late in the disease. More rare is the severe vaso-occlusive disease, often termed "retinal vasculitis", which includes central retinal artery occlusion, multifocal arteriolar occlusions, extensive capillary nonperfusion and central venous oc...

A 56-year-old man was referred to our hospital about 48 h after sudden onset of painless central visual loss in his right eye (OD) on a winter morning. He had a more than 25-year history of systemic hypertension and smoking. Funduscopic observation showed striated retinal whitening in the macular region, faint cotton-wool patches around the optic disc, and segmental narrowing of the retinal art...

Retrobulbar injection has been widely practiced as a technique of ocular anesthesia for many decades. Nevertheless, the technique is not free from complications. Vascular occlusion secondary to retrobulbar injection is rare but can be vision threatening. We report a case series of two such patients who presented with poor vision following retrobulbar injection. Fundus showed pale retina with ch...
