Abstract:A 12-year-old boy presented with best-corrected visual acuity (BCVA) of 6/9 in both eyes following an episode of electric shock. Optical coherence tomography (OCT) showed disruption of the ellipsoid zone as well as retinal pigment epithelium (RPE) layer. Fundus autofluorescence (FAF) showed increased central hypoautofluorescence in both eyes. At 3-month follow-up, BCVA improved to 6/6 with OCT showing spontaneous resolution of maculopathy in both eyes with reorganized RPE layer and ellipsoid zone. To the best … Show more
“…Very mild cases are characterized by RPE and photoreceptor layer disruption. [ 8 ] More commonly, there is an absence of the RPE and the outer retina forming an outer lamellar macular hole with an intact internal limiting membrane overlying the defect. These have been described as intraretinal macular cysts.…”
The aim of the study was to describe the ocular findings following an accidental high-voltage electrical discharge. A 32-year-old male suffered an accidental electric discharge of 10,000 volts of direct current. He developed cortical, nuclear, and posterior subcapsular opacities in both the eyes. The retinal examination showed bilateral macular cysts. Four months after the event, the macular cyst in the OD spontaneously regressed without visual improvement. The macular cyst in the OS remained unchanged. High-voltage electrical discharge can lead to bilateral maculopathy and cataracts. The visual prognosis is reserved. The visual acuity may not improve despite macular cyst regression.
“…13 In the literature, maculopathy has been reported to stabilize and spontaneously recover during follow-up. Ranjan et al 15 reported functional and anatomical recovery in a case who developed an ellipsoid zone defect after an episode of electric shock during the 3-month follow-up. However, complete recovery was present in the mildest form of ESM.…”
A 32-year-old man presented to our clinic with complaint of vision loss in both eyes (oculus utro; OU). Past medical history revealed that he had been exposed to high-voltage electrical current that passed through the temporal region of the head 2 months ago. Slit-lamp examination demonstrated cortico-nuclear cataract and mature cataract in his right eye (oculus dexter; OD) and left eye (oculus sinister; OS), respectively. On fundus examination, a macular hole was observed in OD. Optic atrophy and foveal atrophy were observed in the left fundus examination after cataract surgery. Simultaneous cataract, maculopathy and optic atrophy may occur after high-voltage electrical current injury. Therefore, clinicians should perform detailed anterior and posterior segment examinations in such patients.

“…5 Because higher concentrations of melanin pigments are found in the macula (thicker and tightly packed RPE cells), it causes more production of heat and thermal damage; additionally, although the macula is the most affected site, the entire retina can be affected. 9 Macular manifestations include fullthickness macular hole, macular edema, and cysts. 8,10,11 The extent of tissue damage depends on the current intensity, tissue exposure time, and tissue resistance to the current.…”
Purpose: This is a case report of a male patient who suffered a high-voltage electrical burn and presented with bilateral pigmentary retinopathy. Methods: A 40-year-old man presented with bilateral vision loss following a high-voltage electrical injury sustained 10 years earlier. Family history, ocular history, and anterior segment evaluation were unremarkable. Results: Fundus examination revealed bilateral optic disc pallor, widespread areas of chorioretinal atrophy, and pigmentary changes surrounding the optic disc that partially involved the macula with some spared areas located on the superior retina. Conclusions: Retinal manifestations following a high-voltage electrical injury can resemble other hereditary and inflammatory diseases with similar clinical patterns, therefore, a meticulous family, medical, and clinical evaluation is essential.
