Objective:
To report the clinical and tomographic findings in a case of maculopathy secondary to high-tension electric current strike.
Case Report:
A 27-year-old male refers a reduction in his visual acuity after electric strike. Visual acuity was 0.05 in both eyes. Circular reddish macular lesions measuring 400 micro m in RE and 200 micro m in LE were evident. Optical coherence tomography (OCT) showed intraretinal foveal cysts. At the third month follow-up visit, visual acuity had improved to 0.4 in RE and 0.5 in LE. Clinical and tomographic evaluation showed a reduction of the foveal cysts.
Discussion:
Electricity affects retinal pigment epithelium and retina by thermal denaturation. OCT provides a conclusive diagnosis.
