[Solar retinopathy: follow-up examinations with optical coherence tomography (OCT) and microperimetry]

Solar retinopathy is a phototoxic damage to the central retina. It may cause visual deterioration and a central scotoma with reading difficulties, that usually fade with time. Morphological and functional changes can be very subtle and are often inadequately detected by standard examinations.

The more affected, left eye of a 41-year-old female patient was examined clinically, by optical coherence tomography (OCT 3) and by MP 1-microperimetry during a 6-month follow up after gazing at a partial eclipse.

At all times visual acuity was reduced to 0.7 causing visual deterioration. OCT examinations showed a subfoveal damage of decreasing extent, which was still detectable after 6 months. The retinal affection resulted in a persistent microscotoma of decreasing depth.

OCT 3 and MP 1-microperimetry are able to detect the morphological and the functional damages in solar retinopathy at a level of sensitivity good enough to produce correlating results which allow the detection of subtle changes during follow-up.
