Abstract

Purpose – Anterior visual pathway lesions can cause severe visual loss. We aim to find the proportion of eyes who had thinning of retinal nerve fibre layer (RNFL) and ganglion cell complex (GCC) and their association with visual parameters.

Method – A prospective study was conducted on 37 patients with perichiasmatic brain tumor between February 2019 and June 2020 at a tertiary care institute. Comprehensive neuro-ophthalmological work-up was done in all visits up to 6 months.

Results – Mean age was 35.14±11.98 years. There was an increase in proportion of eyes with RNFL thinning (p=0.02 for inferior quadrant). Maximum GCC thinning was associated with severe visual impairment (VI). Odds of having blindness in eyes with thinned out RNFL (inferior) and GCC was 0.96 (p=0.003) and 0.95 (p=0.03) respectively.

Conclusion – A large proportion of eyes developed RNFL and GCC thinning. The damage was significantly associated with VI. Thinned out RNFL and GCC are predictive factors of blindness.
