- Abstract
AimTo document any correlation between previous acute angle-closure attack and the extent of synechial angle closure in chronic primary angle-closure glaucoma (PACG) patients.MethodsConsecutive cases of chronic PACG with patent peripheral iridotomy had gonioscopy performed. The extents of synechial angle closure of those chronic PACG eyes with previous documented acute angle-closure attack were compared to those eyes without such a history.ResultsA total of 102 chronic PACG eyes of 102 patients were recruited. Twenty-seven eyes (26.5%) had a previous documented acute angle closure, while 75 eyes (73.5%) did not. The mean extent of synechial angle closure ±1 SD was 307±68 degrees (range, 150–360 degrees) in those chronic PACG eyes with a history of previous acute angle closure, compared to 266±89 degrees (range, 90–360 degrees) in those chronic PACG eyes without such a history (P=0.03, Student's t-test). There were no statistically significant differences between the two groups in age, LogMAR visual acuity, intraocular pressure (IOP), number of glaucoma eye drops, vertical cup-to-disk ratio, mean deviation or pattern SD in Humphrey automated perimetry, and anterior chamber depth (P>0.05).ConclusionPrevious acute angle-closure attack correlated with more extensive synechial angle closure in chronic PACG patients in this study.Eye (2009) 23, 920–923; doi:10.1038/eye.2008.108; published online 18 April 2008
