Electrically-induced Cataract and Optic Nerve Alteration (Colour Photography Posterior Pole, VEP)
Lens -> Trauma (Injury)Patient: 25 years of age, male, BCVA 0.4 at OD, 0.2 at OS.
General Medical History: major electrical injury (3000 V) in July 2013 with skin burns on the face, neck, hand, and inner left arm.
Ocular Medical History: 12 months later development of cataract in both eyes with decreased visual acuity.
Purpose: to present electrically induced cataract in both eyes induced by high voltage current.
Methods: Colour Photography Posterior Pole, VEP.
Findings:
Colour Photography Posterior Pole: cataractous changes with characteristic anterior subcapsular opacifications.
VEP: decreased amplitude in OS, regular amplitude in OD.
Discussion:
Saffle et al. reviewed patients suffering major electrical injuries. Patients who suffered cataracts were injured with high (greater than 1,000-v) voltage current. All patients suffered true 'entrance and exit' wounds. Cataracts first presented as decreased visual acuity 1 to 12 months postinjury. Electrical cataracts remain a serious potential complication of electrical injury.
