Abstract

Purpose : The aim of this study was to evaluate anterior chamber volume (ACV), iris volume (IV) provided by Anterior Segment Swept Source-OCT (SS-OCT) in healthy subjects and angle closure glaucoma patients.

Methods : A total of 20 eyes from 20 healthy Chinese subjects with a mean age of 45.5±4.5 years(range:47~65years); and 20 eyes diagnosed with angle closure glaucoma (ACG) from 20 Chinese patients with a mean age of 48.5±7.5 years(range:42~70years) were also enrolled in this study. The anterior chamber volume (ACV) and iris volume (IV) of these subjects were examined using a SS-OCT. The independent samples t test was performed to compare the ACV, IV of the healthy subjects and ACG patients.

Results : Mean ACV, and IV for all healthy subjects were 152.59±29.96 mm*3(range:171.06~56.61 mm*3),and 34.20±4.39mm*3(range:19.77~44.42 mm*3). Mean ACV, and IV for ACG patients were 74.70±16.99 mm*3(range:112.89~47.02 mm*3),and 27.47±6.22mm*3(range:12.75~40.22 mm*3). Significant differences were found between healthy subjects and ACG patients (p<0.05).Compared with healthy subjects, ACG patients had less ACV and IV.

Conclusions : ACG patients presented a significant decrease in ACV, it maybe manifested that volume of anterior chamber was a good indicator for ACG. The results also suggested that iris atrophy widely existed in ACG patients.
