ABSTRACT

Conclusions:

The vertical C/D ratio that measured with ophthalmoscopic examination by assistant of ophthalmology will be different from vertical C/D ratio obtained by optic nerve head analyses of optical cohorence tomography.

Results:

Thirty patients were male and 42 patients were female, mean age was 51.43±19.2. Mean vertical C/D ratio measured by second year asisstant was 0.556±0.246, mean vertical C/D ratio measured by third year assistant was 0.534±0.251, mean vertical C/D ratio measured by fourth year assistant was 0.529±0.250. Mean vertical C/D ratio obtained by optical cohorence tomography was 0.651±0.223. There was no statistically signicant differences among vertical C/D ratio measured by assistants (p>0.05). The mean vertical C/D ratio that measured by each assistant was statistically lower than obtained by optical cohorence tomography (p<0.05).

Materials and Methods:

One hundred and ten eyes of 72 glaucoma patients which are followed in glaucoma unit were included to study. Each assistant examined vertical C/D ratio by Goldman tree mirror lens and results were recorded independently from results of the other assistants. The measurements of vertical C/D ratio were obtained by optic nerve head analyses of Stratus Optical Cohorence Tomography after pupillary dilatation and vertical C/D ratio were enlisted. All easurements of vertical C/D ratio were compared each other.

Purpose:

To compare vertical C/D ratio that measured with ophthalmoscopic examination of second, third and fourth year assistant of ophthalmology with vertical C/D ratio obtained by optical cohorence tomography.
