Comparative study of retinal ganglion cell complex thickness with retinal nerve fibre layer and visual field changes in cases of suspicious disc or glaucoma suspect

Purpose: To compare and correlate macular ganglion cell complex thickness (GCC) with retinal nerve fibre layer (RNFL) and visual field (VF) changes in cases of suspicious disc or glaucoma suspect. Methods: A total of 60 glaucoma suspects, were included in the study group.  These patients were subjected to standard investigations for glaucoma like tonometry, central corneal thickness (CCT), gonioscopy and fundoscopy. Visual fields were assessed using automated static perimetry of Humphrey Automated Visual Field Analyser. The test used was central 30-2 SITA standard. optical coherence tomography was done using RTvue, model 100 (version 5.1) to assess retinal nerve fiber layer (RNFL) and macular ganglion Cell complex thickness (GCC). Correlation of RNFL and GCC was evaluated using Pearson’s correlation coefficient and correlation between GCC and VF was assessed using two independent sample t –test. Results: A total of 60 eyes of 60 glaucoma suspects, were enrolled in the study both males and females were included
