Abstract Details


It is a known fact that ganglion cell loss precedes RNFL loss in patients with early Glaucoma. The purpose of our study is to know the repeatability of the ganglion cell thickness measurements with the OPTOVUE RT-100 OCT machine.


Sundar Eye Hospital, India


10 consecutive readings of Ganglion cell thickness measurements were done for 6 eyes of 3 people . The program included GCC average, Superior, Inferior, Superior-Inferior, FLV .


The standard Deviation ranged from 0.62 and 1.44microns.


The repeatability of the GCC thickness with the Optovue RT-100 machine appears to be good with low SD.
