Indian Journal of Clinical and Experimental Ophthalmology (IJCEO) is open access, a peer-reviewed medical journal, published quarterly, online, and in print, by the Innovative Education and Scientific Research Foundation (IESRF) since 2015. To fulfil our aim of rapid dissemination of knowledge, we publish articles ‘Ahead of Print’ on acceptance. In addition, the journal allows free access (Open Access) to its content, which is likely to attract more readers and citations of articles published in IJCEO.

Abstract
Aim: To find the correlation between visual field and retinal nerve layer thickness in adult North Indian population from Gurugram region with glaucoma suspect.
Materials and Methods: Correlative and quantitative study was carried between the visual field and retinal nerve fiber layer (RNFL) thickness of 400 adult eyes. The age of subjects participating in the study ranged between 18 to 80 years with mean age 45 ± 14years. The standard automated perimetry was acquired by Humphrey visual field analyser using 24-2 SITA standard strategy. Retinal nerve fiber layer thickness was measured by Spectral Domain OCT (3D OCT2000FA). Visual field was performed on the same day or within ± three months of OCT acquisition. Statistical analysis was performed using MS Excel, SPSS (ver.20) and other descriptive statistical tools.
Results: The mean MD and PSD were -2.79 dB ±2.21 and 2.52 dB ±1.49, respectively. The average thickness of RNFL of the four quadrants calculated was 98.40 µm±10.70. RNFL thickness in an inferior and superior quadrant was 122.49µm ± 16.71 and 118.86 µm ±15.21 respectively. The mean cup to disc area ratio (CDAR) in the glaucoma suspect subject was 0.60± 0.10, and the vertical cup to disc ratio (VCDR) was 0.74± 0.074. Correlation of the average RNFL thickness, Inferior RNFL thickness and superior RNFL thickness with GHT was 0.245(P=0.011), 0.19 (P=0.094) and 0.27, (P=0.004), respectively. Superior RNFL thickness showed a more significant Correlation (r= 0.193, P<0>
Conclusion: Retinal nerve fiber layer thickness demonstrated a weak to mild and statistically significant correlation with the visual field. The correlation of average RNFL thickness with Visual field global indices and parameters were significant but weaker. Correlation between superior RNFL thicknesses was highest with GHT in adult North India Gurugram subjects with glaucoma suspect. Superior RNFL thickness showed a higher Correlation with Mean deviation (MD) and VFI of the visual field
