  • Look Inside

A patient with ocular symptoms due to electric lightning shock was reported. Electric burn of 1 st or 2 nd degree over 30% of body surface ruptured tympanic membrane, numbness of lower extrimities and absect tendon reflex in the lower extrimities were also existed. His ophthalmological chief complaint at his first visit to our clinic 30 days after injury was upper temporal visual field defect in the right eye. Visual acuity was 20/20 (n. c.) OD and 20/15 (n. c.) OS. One month later, fine subcap-sular cataract was found in the anterior lens epith-elium which was developed to crown-shaped opac-ity within the following one month. Six months after the injury, anteriorsubcapsular opacity was exacerbated and visual acuity decreased to 20/200 (n. c.). ERG examination revealed extinct oscil-latory potentials in the right eye, diminution of b-wave and delayed peak latencies of a-wave in both eyes. These changes were improved in the follow-up studies. Progressive chorioretinal atro-phic spots were developed around just temporal mid-periphery in the right eye and just nasal midperiphery in the left eye. These atrophic lesions could not find at the initial examination.
