A Case of Bilateral Continuous Central Retinal Artery Occlusion

We report a case of bilateral simultaneous central retinal artery occlusion (CRAO). The time lag was 21 hours. The patient was a 78-year-old woman. She had hypertension, arteriosclerosis, and bilateral thrombosis of the legs. Both eyes could only distinguish light and dark at the first medical examination. We started steroid and urokinase therapy and used a vasodilator of peripheral vessels. When the patient left the hospital, visual acuity had improved to the ability of counting fingers (0.01 leftward 30 cm on the left). Both visual field and color vision had improved slightly. We think this bilateral CRAO resulted from thrombosis of both central retinal arteries at almost the same time.

Bilateral central retinal artery occlusions in a patient with activated protein C resistance

We describe the case of a 42‐year‐old woman who had two episodes of visual loss, first in one and later in the other eye, which caused bilateral reduction of visual acuity to 2/10 with optic atrophy. Detailed clinical and laboratory assessment revealed an activated protein C (APC) resistance and no other obvious cause. APC resistance has not been previously reported as an etiologic factor of central retinal artery occlusion.

Bilateral blindness in cavernous sinus thrombosis

An unusual case of bilateral blindness secondary to a cavernous sinus thrombosis is reported. A woman who had undergone reconstructive surgery after tumor resection of the floor of the mouth, was readmitted 1 month later with bilateral proptosis and signs of sepsis. There were no complaints of blurred vision. A CT-scan of the orbits demonstrated a bilateral cavernous sinus thrombosis (CST) secondary to an infection at the skull base behind the myocutaneous flap. A few days later she became blind, due to bilateral central retinal artery occlusion and anterior ischemic optic neuropathy. The general critical condition improved with intensive AB treatment. The patient recovered well without neurological defects apart from her permanent bilateral blindness. There were no signs of tumor recurrence. To our knowledge, this is the first documented case of bilateral blindness in a patient suffering from CST.

Bilateral central retinal artery occlusion in homocystinuria. A case report.

This article reports the first known case of bilateral central retinal artery occlusion associated with homocystinuria. Vascular occlusion may well explain cases of optic atrophy and sclerotic vessels which have been reported in the past.

Bilateral Central Retinal Artery Occlusion

Occlusion of a central artery of the retina is a not uncommon occurrence. It is usually associated with arteriosclerosis, or less often with embolization from endocarditis, but may also be seen with syphilis, periarteritis nodosa, polycythemia vera, thromboangiitis obliterans, and temporal arteritis. A much rarer condition, however, is the occlusion of both central retinal arteries. The following is a case report of a Negro woman with proved systemic lupus erythematosus, sickle cell trait, and active pulmonary tuberculosis who suffered complete occlusion of the left central retinal artery, followed 13 days later by complete occlusion of the right central artery. This patient was treated with cortisone. REPORT OF A CASE A 36-year-old Negro housewife was admitted to the University Division Chest Service of Kings County Hospital on May 21, 1954, because of malaise, fever, and productive cough. In 1951 the patient began to have mild temperature elevation, cervical adenopathy, and progressive

Simultaneous Closure of all the Central Retinal Vessels

A case of bilateral central retinal artery and vein occlusion is described, its onset immediately consequent upon a tooth extraction. The author offers the most likely etiologic possibilities but draws no definitive conclusions. From the Neurological and Ophthalmological Services of the Montefiore Hospital.
