Objective:To estimate the prevalence of primary angle-closure glaucoma,primary angle closure(PAC),and primary angleclosure suspect(PACS)and its associated risk factors in a rural population in southern India.Methods:Three thousand and nine hundred thirty-four(81.95%)of 4800 enumerated subjects aged 40 years or older underwent a complete ophthalmic examination,including compression gonioscopy.Glaucoma was diagnosed using International Society of Geographical and Epidemiological Ophthalmology classification.Results:Data were analyzed for 3924 subjects(81.75%).Primary angleclosure glaucoma was diagnosed in 34 subjects(0.87% ;95% confidence interval CI,0.58 to 1.16)(27 women,7 men).The mean intraocular pressure was 20.71± 9.24 mm Hg.One subject(2.94%)was blind.Twenty-eight subjects(0.71% ;95% CI,0.45 to 0.98)were diagnosed to have PAC(21 women,7 men).Eleven subjects(39.3%)had an intraocular pressure greater than 21 mm Hg,13 subjects(46.43%)had peripheral anterior synechiae,and 4 subjects(14.29%)had both.Two hundred forty-six subjects(6.27% ;95% CI,5.51 to 7.03)had PACS(168 women,78 men).Primary angle closure and primary angle-closure glaucoma were more common in women(age-adjusted odds ratio,3.02;95% CI,1.66 to 5.51)with an increasing prevalence with age.Increasing intraocular pressure was associated with the disease(odds ratio,1.14;95% CI,1.09 to 1.19).There was no association with hypertension and hyperopia.Axial length and anterior chamber depth were longer in the normal group than in the 3 groups with angle closure(P <.05).Women had shorter axial lengths than men(P <.001)in the angle closure groups.Conclusions:The overall prevalence of primary angle closures(PAC and primary angleclosure glaucoma)in a rural population of southern India was 1.58%.There was a female preponderance,and the disease tends to be asymptomatic.
Objective: To estimate the prevalence of primary angle-closure glaucoma, primary angle closure (PAC), and primary angleclosure suspect (PACS) and its associated risk factors in a rural population in southern India. Methods: Three thousand and nine hundred thirty-four (81.95%) of 4800 enumerated subjects aged 40 years or older underwent a complete ophthalmic examination, including compression gonioscopy. Glaucoma was diagnosed using International Society of Geographical and Epidemiological Ophthalmology classification. Results: Data were analyzed for 3924 subjects (81.75%). Primary The mean intraocular pressure was 20.71 ± 9.24 mm Hg.One subject (2.94%) was blind.Twenty-three (95% confidence interval CI, 0.58 to 1.16) (27 women, 7 men) Subjects (39.3%) had an intraocular pressure greater than 21 mm Hg, 13 subjects (46.43%) had peripheral anterior synechiae, and 4 subjects ( Had PACS (168 women, 78 men). Primary angle closure and primary angle-closure glaucoma were more common in women (age: 14.29%) had both.Two hundred forty- six subjects (6.27%; 95% CI, 5.51 to 7.03) -adjusted odds ratio, 3.02; 95% CI, 1.66 to 5.51) with an increasing prevalence with age. Increasing intraocular pressure was associated with the disease (odds ratio, 1.14; 95% CI, 1.09 to 1.19) hypertension and hyperopia. Axial length and anterior chamber depth were longer in the normal group than in the 3 groups with angle closure (P <.05) .Women had shorter axial lengths than men (P <.001) in the angle closure groups. Conclusions: The overall prevalence of primary angle closures (PAC and primary angleclosure glaucoma) in a rural population of southern India was 1.58%. There was a female preponderance, and the disease tends to be asymptomatic.
