Abstract

PURPOSE:

To describe a patient presenting with typical signs of vascular occlusive retinopathy.

DESIGN:

Observational case report.

METHODS:

A 65-year-old man experienced painless unilateral loss of vision to 4/20 in his left eye. Ophthalmoscopy of the left eye showed pronounced attenuation of the retinal arterioles, ischemic retinal edema, and a few intraretinal hemorrhages. Fluorescein angiography revealed a diffusely reduced retinal perfusion typical of retinal occlusive disease. Using a new ophthalmodynamometer with a pressure sensor at the mounting support of a conventional Goldmann contact lens, we additionally measured the diastolic central retinal artery collapse pressure.

RESULTS:

The diastolic central retinal artery collapse pressure was significantly lower in the left eye than in the right eye (14.7 +/- 2.4 relative units vs 51.7 +/- 4.3 relative units; P <.001). Both values were significantly (P =.03) lower than those in a control group (80.9 +/- 6.9 relative units). Doppler sonography revealed a total occlusion of the left carotid artery and a nonrelevant stenosis of the right carotid artery.

CONCLUSIONS:

A new ophthalmodynamometric device consisting of a pressure sensor at the mounting support of a Goldmann contact lens was helpful in detecting carotid artery occlusion leading to ischemic ophthalmopathy.
