Assessment of angle of anterior chamber with SD-OCT in patients presenting to tertiary health care center

Purpose: To evaluate the angle of anterior chamber with SD-OCT in patients above 40 years of age presenting to tertiary health care center in central India. Materials and Methods: 120 Consecutive patients (240 eyes) above 40 years of age presenting to ophthalmology OPD of tertiary health care center were enrolled in a cross-sectional study. All patients underwent comprehensive ocular examination with included best corrected visual acuity, slit lamp, fundus, gonioscopy, intraocular pressure (IOP), evaluation of angle (i.e. AOD, TISA, TIA) of anterior chamber with SD-OCT. The duration of study was one year six months. Result: The mean age was 53.94 years. There were 61 males & 59 females. It was noted that mean nasal & temporal AOD was less in females (0.4175 µm, 0.4142 µm) as compared to males (0.4583 µm, 0.4613 µm). We found that older people have a narrower anterior chamber angle i.e. from 40-60 years of age mean TIA nasal & temporal was 29.13, 27.53 degree & above 60 years of age mean TIA nasal & temporal was-24.13, 22.63 degrees. Conclusion: We found that AOD is less in female as compared to male. It was also noted that older people have a narrower anterior chamber angle as compared to younger people. The gonioscopy has been considered as the gold standard for characterizing the ACA, but it is contact procedure, subjective and requires the expertise while the OCT is rapid, quantitative, reproducibility, non-contact procedure with less interobserver variability will help us to accurately assess anterior chamber angle.
