Lung carcinoma presenting as monocular painless blindness

Abstract

To discuss a very rare presentation of lung malignancy which results in visual disturbance as first and only clinical manifestation. Case report. We report a case of otherwise asymptomatic 32-year-old, nonsmoker female presenting with painless loss of vision in the right eye and photophobia in the left eye, owing to secondaries in choroid from lung carcinoma. Patient was worked up after admission in our hospital to ascertain the cause of blindness and subsequently revealed lung malignancy with widespread metastasis involving multiple organ systems. Despite widespread malignant involvement patient was completely asymptomatic and active except for visual disturbances. This case further emphasized the necessity of prompt and priority-based evaluation of patients for lung carcinoma whenever doubtful intraocular lesions are noted, regardless of age or smoking status. It seems that these cases represent a distinct subset of lung malignancy.
