Abstract
Introduction: Papilledema results in visual dysfunction, which is often caused by a brain tumor. Decreased color sensitivity may be manifest earlier than visual acuity in papilledema, but the correlation of color sensitivity to retinal nerve fibre layer (RNFL) is not yet determined. Therefore, this study aimed to determine the correlation between color vision and retinal nerve fibre layer thickness in papilledema
Methods: This was an analytic retrospective study with a cross-sectional design using medical records of patients diagnosed with papilledema in the Neuro-Ophthalmology clinic between January 2016 and December 2020.
Results: There were 102 patients (204 eyes) enrolled in this study, with a median age was 41 years old. There were 32 (31%) males and 70 (69%) females. Most head CT scan results were intracranial tumors in 88 patients (87.52%). The median value of color vision was 2,63% and the median of retinal nerve fibre layer average thickness was 179,50 µm. Statistical analysis showed a very weak correlation between color vision with retinal nerve fibre layer mean thickness (r = 0.185, r < 0.2).
Conclusion: There is no statistically significant correlation between color vision with RNFL layer thickness in patients with papilledema.
