ABSTRACT.Purpose: We describe a 39-year-old Japanese woman with chronic angle closure glaucoma secondary to spherophakia and frail zonular fibres. The patient was 143 cm in height with short fingers and had no family history of eye problems. High intraocular pressure, total optic disc cupping and severe visual field constriction were found in the right eye. Case ReportA 39-year-old Japanese woman presented with decreased vision in her right eye on June 7, 2000. She had suffered high myopia bilaterally since childhood and her medical and familial histories were not significant. Her father and mother were 150 cm in height, while her two brothers were 155 cm and 160 cm in height. She was the eldest child and her parents were not relatives. She did not have any children and none of her family complained of eye trouble.The subject's visual acuity was 0.01 (0.

Pattern visual evoked potentials (pVEPs) were used to assess the visual function before, and 1 and 6 months after removal of an idiopathic epiretinal membrane (ERM) from eight eyes. All patients underwent a standard three-port pars plana vitrectomy to remove the ERM removal and cataract surgery. pVEPs were elicited by check sizes of 15', 30', 60', and 120' with a reversal rate of 2 reversals/s. One hundred responses were averaged with an analysis time of 300 ms. The amplitude ratio (affected eye/fellow eye) of the P100 component were significantly larger at 6 months with smaller check sizes, and the increase was accompanied by an improvement of the VA. The mean peak latency of P100 did not change significantly for all check sizes. We conclude that the improvement of the P100 amplitude with smaller check sizes resulted from the recovery of visual function after the ERM removal.
