Abstract:
Biometric measurements were made by ultrasonography in 30 eyes of 25 patients (18 Women and 7 men, mean 67.9 yrs) with acute angle closure glaucoma against 52 eyes of 26 age-matched normal persons (20 women and 6 men, mean 65.1 yrs) in order to analyze an affecting factor of lens in acute primary angle closure glaucoma. The 26 eyes of 30 patients' eyes was subjects older than 60 years of age and mean intraocular pressure was 57.06 +/- 16.764 mmHg The mean anterior chamber depth of these patients (1.895 +/- 0.193 mm) was 0.95mm shallower than one of controls (2.840 +/- 0.324 mm). The mean lens thickness was slgmtlCantly larger tor pal1ents (patients 5.024 +/- 0.498 mm, controls 4.168 +/- 0.524 mm, p=0.001). The mean axial length was 0.6 mm shorter for patients (patients 22.385 +/- 0.840 mm, controls 22.985 +/- 0.838 mm, p<0.01). The relative lens position was significantly smaller for patients (patients 0.194, controls 0.214, p=0.0001), but relative posterior capsule position was similar in two groups. The study suggested that the increased thickness and forward positioning of lens was one of important factors for anterior chamber angle closure in primary angle closure glaucoma.
