Retinopatía por eclipse: A propósito de tres casos

Abstract

Eclipse retinopathy is a maculopathy that occurs after exposure to intense solar radiation, such as occurs during an eclipse, and is produced by a photochemical mechanism. Although the macular changes and symptoms are usually reversible, residual defects at the level of the EPR and scotoma in visual fields can occur. For these reasons the most appropriate treatment is prevention by means of public awareness campaigns.

Solar maculopathy: prognosis over one year follow up

“…The visual acuity improvement started after 7 to 10 days, this agreed with previous studies [22, 23] In all cases, an improvement in vision developed gradually until 6 months after exposure, then the vision became stationary and did not deteriorate and did not show further improvement. Although OCT shows an outer retinal hole disruption in 80% of cases and no significant macular abnormalities in 20% (this case whose eyes regained VA of 1), The persistent foveal changes in solar maculopathy is variable, many studies reported persistent foveal damage after 6 months as told by Wong [24] and Doyle [6] who reported a pseudohole in 7 eyes in a duration ranged from 3 to 12 months.…”

“…22 La afectación es generalmente bilateral, aunque asimétrica. 23 Por otro lado, la radiación solar también afecta el cristalino, el cual absorbe principalmente casi toda la radiación comprendida entre 295 y 400 Nm, este proceso desencadena una alteración de las proteínas del cristalino y una acumulación de sustancias fluorescentes, que reducen la cantidad de radiación ultravioleta visible que llega a la retina, al actuar como un filtro eficaz e incrementar el color amarillento del núcleo. Este fenómeno puede evolucionar hacia una catarata si la exposición solar es excesiva.…”
