ABSTRACT
PURPOSE:
To describe the first case of a combined sub-hyaloid and sub-internal limiting membrane macular hemorrhage after recreational laser exposure.METHODS:
A 23-year-old patient presented with an acute loss of vision in his right eye (OD) immediately after a brief exposure to a laser beam at a music festival. Color photography, spectral-domain optical coherence tomography (SD-OCT), and multifocal electroretinogram (mfERG) were performed for diagnosis and follow-up.RESULTS:
On presentation, visual acuity was 20/400 in the OD and 20/20 in the left eye. Posterior segment examination of his OD revealed a preretinal hemorrhage at the macula. SD-OCT images exposed a combined sub-hyaloid and sub-internal limiting membrane localization. Successful VPP with ILM peeling was carried out. Although sequential mfERG displayed almost complete restoration of the P1 amplitude 6 months posterior to VPP, SD-OCT demonstrated permanent damage to outer retinal layers. Final BCVA on OD was 20/30.CONCLUSION:
The expanding and unregulated use of lasers in everyday life has created an increasing amount of cases of laser-induced retinopathy in recent years. Much more attention should be addressed in laser safety and awareness to prevent future ocular injuries. In acute phases of sub-hyaloid hemorrhages blocking direct visualization of the posterior pole, mfERG is a valuable tool to address initial macular pathology.Palavras-chave
