Abstract Details

Purpose:

To assess diagnostic capability of GCC and Retinal Nerve Fiber Layer (RNFL) thickness measured by SD-OCT for detection of glaucoma

Setting:

The study was conducted in Laxmi Eye Institute, Panvel, Maharashtra, India

Methods:

RNFL and GCC thickness on SD-OCT of 121 eyes of 64 patients were analyzed. The gold standard for glaucoma diagnosis was Humphrey visual fields 30-2, fulfilling Anderson's criteria.

Results:

The mean age was 51.6 years (SD 16.4). The sensitivity of GCC and RNFL was 100% (95% CI: 93.2% -100%) & 88.5% (95% CI: 76.6-95.6) respectively. The specificity of GCC and RNFL was 59.4% (95% CI: 46.9%-71.1%) & 60.9% (95% CI 48.4-72.4) respectively for diagnosis of glaucoma. The positive predictive value was 65% (95% CI: 53.5%-75.3%) and negative predictive value was 100% (95% CI: 91.4%-100%).

Conclusions:

GCC imaging using SD-OCT is a highly sensitive ancillary modality for detection of early macular changes in glaucomatous eyes.
