Branch retinal arterial occlusion treated with intravenous prostaglandin e1 and steroids.

OBJECTIVE

To present the use of 6-methylprednisolone IV and prostaglandin E1 IV, a powerful vasodilator of the microcirculation, in the treatment of a branch retinal arterial occlusion.

METHODS

A 63-year-old man presented with a 3-hour history of a sudden loss of vision in the right eye. On ophthalmic examination, the diagnosis of a superior temporal branch retinal arterial occlusion was made. The patient was immediately given 40 mg of 6-methylprednisolone IV for more than 5 minutes followed by 80 μg of prostaglandin E1 with 2 milliequivalents of potassium IV for more than 3 hours. The same treatment was repeated the following morning.

RESULTS

The visual acuity in the right eye improved from 2/10 at presentation to 7/10 at the end of the second day of treatment. Clinically, there was a reduction of the posterior pole edema. Eleven days after treatment, the visual acuity was 9/10 with no retinal edema.

CONCLUSIONS

Immediate prostaglandin E1 IV and steroids should be considered in cases of recent-onset branch retinal arterial occlusion to restore retinal blood flow and improve visual acuity.
