 Case Report



A 40-year-old male was struck by lightning resulting in loss of consciousness. Ten months later, he presented with complaints of metamorphopsia in the left eye. The best-corrected visual acuity was 6/6, N6 in the right eye and 6/7.5, N6 in the left eye. Anterior segment examination was normal. Fundus examination of the left eye revealed a lamellar hole at macula and a group of pigment clumps arranged in a wedge-shaped pattern in the temporal periphery of retina [Figure 1]. Fundus fluorescein angiogram of the left eye revealed retinal pigment epithelium (RPE) window defects at fovea and blocked fluorescence in the temporal periphery due to pigments, better seen on red-free photograph [Figure 2] and [Figure 3]. Spectral domain optical coherence tomography (SD-OCT) analysis of the left eye demonstrated a lamellar hole with intraretinal cystic spaces and a defect in the inner segment/outer segment (IS-OS) junction [Figure 4]. Fundus examination and imaging studies in the right eye were normal.{Figure 1}{Figure 2}{Figure 3}{Figure 4}

 Discussion



Lightning-induced maculopathy is caused by the heat generated at the level of RPE due to resistance by melanin.[1] It often manifests as cystoid macular edema and macular hole.[2],[3]

SD-OCT analysis shows loss of foveal photoreceptors and IS-OS junction disruption.[4] Peripheral pigmentary changes following lightning injury as seen in our patient have also been described in the literature.[4] Visual prognosis in patients with lightning-induced ocular injury depends on the extent of irreversible retinal and macular damage. Therefore, long-term follow-up of these patients is recommended.
