Sudden Vascular Obstruction of the Central Vessels of the Eye
When the eye is involved in a vascular accident, the treatment and prognosis always constitute a serious problem. After even small hemorrhages the eye rarely returns to normal and with a massive hemorrhage, a large percentage of the vision may be lost. Sudden loss of vision is usually due to thrombosis of the central vein or embolus of the central artery. The diagnosis is easily made by ophthalmoscopic examination as is illustrated by the following two cases.
Report of Cases
Case 1: The patient was a white man, 50 years of age, who was first seen on August 22, 1938. Ten days before examination, he first noticed dimness of vision in the right eye. This condition became much more severe the following day, and he consulted his oculist whose examination revealed the vision in the right eye to be 6/60, in the left eye 6/12, and corrected vision, right eye 6/30, left eye 6/6. The examination of the right eye had shown it to be essentially normal except for the disc which was swollen and the margin was indistinct; the blood vessels were thrombosed; there were numerous hemorrhages and a few white exudative spots. The blood pressure at that time was 130 systolic, 80 diastolic. The previous medical history was irrelevant except for a high blood pressure in 1934.
Examination: When the patient was seen at the Clinic on August 22, vision in the right eye was 4/60 and in the left eye 6/60 plus 1. The lids, iris, conjunctiva, . . .
