Aim: To compare theevaluation results of two experienced clinicians about examination of optic discs in glaucoma patients and healthy inidividuals by stereophotometry and scanning laser ophthalmoscopy. Material and Method: We studied 116 individuals (217 eyes) who were divided as normal, glaucoma and suspected glaucoma in numbers of 54, 42 and 20 respectively. Stereo-photometric photographs of optic disc were examined with fundus camera (Zeiss, FF 450 plus). Optic disc was also evaluated with HRT-3 in the same visit. Two experienced clinicians evaluated the cup/disc ratios and whether the optic discs were glaucomatous or not. Evaluation results were analysed and compared with HRT-3 examinations. Results: There were no significant age and gende rdifferences between the groups(p>0.05). Stereophotographic C/D ratio correlations between the clinicians were 0.79 (p<0.001) in theright-eyesand 0.82 (p<0.001) in thelefteyes. Correlationbetween C/D ratios of the-firstclinicianexaminationand HRT-3 was 0.57 (p<0.001) in therighteyesand 0.50 (p<0.001) in thelefteyes. Correlationratios of thesecondclinicianwas 0.66 (p<0.001) in therighteyesand 0.68 (p<0.001) in thelefteyes. Consistency of thefirstclinician in means of correlation of stereographyand HRT-3 C/Dratioswas %51.2 (p<0.001) in therighteyesand % 47.5 (p<0.001) in thelefteyes. Consistencyforthesecondclinicianwas 0.40 (p<0.001) in therighteyesand % 62.7 (p<0.001) in thelefteyes. Discussion: Although the consistency between the clinician was well, consistency between the clinicians and HRT-3 was in lower rates. Imaging methods were insufficient in glaucoma suspected eyes despite both of methods was effective in the discrimination of normal and glaucomatous eyes.
