OCT findings in patients with retinopathy after watching a solar eclipse.

PURPOSE

To evaluate the optical coherence tomography (OCT) findings in patients with solar retinopathy after watching a solar eclipse.

METHODS

Complete ocular examinations and OCT were done in 4 patients presenting with acute solar retinopathy soon after observation of an eclipse. All 4 patients repeated the examinations about 1 month and 1 year after the first visit.

RESULTS

The symptoms and fundus findings were similar in all patients; all eyes were emmetropic. However, the OCT images were different in all patients, and the alterations were at different levels. The most evident alterations shown by OCT were: a reduction in the intensity of reflectiveness of the retinal pigment epithelium in 3 cases; intraretinal nonreflective spaces between the inner retinal layers in 2 cases; increased reflectiveness of the inner retinal layers in 2 cases, and a round hyperreflective formation in the vitreous just in front of the fovea in 1 case. All these OCT alterations disappeared after 1 month.

CONCLUSIONS

The retinal damage arising soon after exposure to sunlight showed many different aspects in the OCT images of the 4 cases examined. All retinal layers seemed to be altered, but these alterations disappeared after 1 month, and the OCT findings remained the same after 1 year.
