In clinical diagnostics and follow-up, description of the optic disc, estimation of the cup/disc –ratio, or a drawing are not as accurate as optic disc photography, e.g. over 80% of disc haemorrhages may be missed during clinical examination.
Study
The purpose of the study was to compare the rates of detection of optic disc hemorrhages by clinical examination and by review of optic disc photographs at the Optic Disc Reading Center (ODRC) in the annual disc photographs of the Ocular Hypertension Treatment Study (OHTS). Both eyes of 1618 participants were examined for optic disc hemorrhages every 6 months by clinical examination, with dilated fundus examinations every 12 months, and by annual review of stereoscopic disc photographs at the ODRC. Median follow-up was 96.3 months.
Stereophotography-confirmed glaucomatous optic disc hemorrhages were detected in 128 eyes of 123 participants before the POAG end point. Twenty-one cases (16%) were detected by both clinical examination and review of photographs, and 107 cases (84%) were detected only by review of photographs (P<0.0001) «Budenz DL, Anderson DR, Feuer WJ ym.
