Intraobserver and interobserver agreement among anterior chamber angle evaluations using automated 360-degree gonio-photos.

ABSTRACT:

Purpose

To investigate the reproducibility for the iridocorneal angle evaluations using the pictures obtained by a gonioscopic camera, Gonioscope GS-1 (Nidek Co., Gamagori, Japan).

Methods

The pragmatic within-patient comparative diagnostic evaluations for 140 GS-1 gonio-images obtained from 35 eyes of 35 patients at four ocular sectors (superior, temporal, inferior, and nasal angles) were conducted by five independent ophthalmologists including three glaucoma specialists in a masked fashion twice, 1 week apart. We undertook the observer agreement and correlation analyses of Scheie's angle width and pigmentation gradings and detection of peripheral anterior synechia and Sampaolesi line.

Results

The respective Fleiss' kappa values for the four elements between manual g
