Evaluation of practices of macular ganglion cell complex scan in early detection of glaucoma.

The purpose of this survey was to evaluate the level of awareness and practices regarding macular ganglion cell complex (GCC) scans for early detection of glaucoma. The study design was descriptive cross-sectional and the sampling technique was non-probability convenient method. Data was collected through an online survey, from 100 practicing ophthalmologists and optometrists of Pakistan in two weeks, from January 20 to February 03 2019. Data were analysed using Microsoft Excel 2016. From the results it is strongly evident that significant number of respondents recorded the retinal nerve fibre layer (RNFL) to be the first layer affected as glaucoma progresses, which depicts lack of knowledge among eye care practitioners. Furthermore, both the groups (ophthalmologists and optometrists), used macular GCC scan the least as compared to the RNFL (optic nerve head) scan and visual field tests for early diagnosis of glaucoma. It demonstrated lack of knowledge and practices of macular GCC scan for glaucoma among eye care practitioners.
