Abstract
Paraneoplastic visual syndromes are rare group of disorders due to immune mediated pathogenesis. Paraneoplastic optic neuropathy is predominantly bilateral and present with progressive painless visual loss. In our case report, 63-year-old woman presents with sequential bilateral loss of vision and on investigation was found to have adenocarcinoma of the lung. Treatment with concomitant chemotherapy and immunotherapy resulted in significant stability in her vision. She had finger counting in the left and visual acuity for the right eye was 400/20. She also noted deranged color perception. Her neurological examination was unremarkable. The cranial nerves V1-V3 were intact, tongue was midline without any fasciculation . She did not had any facial asymmetry and Romberg’s test was negative. Initial CT scan did not showed any intracranial pathology. On PET scan from June 2021 showed intensely avid 1.7 x 2.9 cm right upper lobe uptake with SUV of 7.
