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.

RESUMENObjetivos: Analizar cambios en el espesor de la capa de fibras nerviosas de la retina (CFNR) peripapilar tras cirugía de cataratas. Métodos: Medición del espesor medio de la CFNR de pacientes sometidos a cirugía de cataratas utilizando tomografía de coherencia óptica (OCT) III Stratus ® antes de la cirugía, un día después de la intervención y transcurrido un mes. Los datos fueron analizados mediante el programa informático SPSS 12.0. Los resultados fueron comparados empleando el test pareado de dos colas t de Student. Resultados: El grupo de estudio estaba compuesto de 74 ojos de 74 pacientes. El espesor medio de la CFNR antes de la cirugía de cataratas (AVGT0) fue 90,71 µm (DE: 19,93), el día después de la cirugía (AVGT1) fue 88,30 µm (DE: 20,59); y un mes después (AVGT2) 97,45 µm (DE: 14,30). No se encontraron diferencias estadísticamente significativas entre AVGT0 y AVGT1 (P=0,37); sin embargo, dicha diferencia sí se encontró entre AVGT1 y AVGT2 (P= 0,002). También se encontró diferencia ABSTRACT Purpose: To analyze changes in peripapillary retinal nerve fiber layer (RNFL) after cataract surgery. Methods: The average RFNL thickness of patients who underwent cataract surgery was measured using the optical coherence tomography (OCT) III Stratus ® before surgery, the day after and one month later. The data were analyzed using the SPSS 12.0 software. We used paired two tail student´s t test for comparisons. Results: The study group was composed by 74 eyes of 74 patients. The RNFL thickness average was 90.71 µm (SD: 19.93), 88.30 µm (SD: 20.59) and 97.45 µm (SD: 14.30), before cataract surgery (AVGT0), the day after surgery (AVGT1) and one month later (AVGT2) respectively. We did not find statistically significant difference between AVGT0 and AVGT1 (P=0.37); however, statistically significant difference between AVGT1 and AVGT2 (P= 0.002) as well as in the image signal quality between AVGT0 and AVGT2 (P= 0.0001). Conclusions:The RNFL average thickness measured by OCT III Stratus ® showed an increase one
