Bilateral visual blurring as the first symptom of extra-cranial metastatic lung carcinoma

Symptomatic choroidal metastasis in a know case of metastatic lung carcinoma is rare. However recent onset blurring of vision in patient of lung carcinoma should raise strong suspicion for choroidal metastasis. Thorough ophthalmological evaluation including bilateral visual activity, fundoscopy, ultrasonography and magnetic resonance imaging of orbit should be done to establish the diagnosis, palliative external beam radiotherapy given for symptomatic choroidal metastasis leads to preservation of useful vision and functional independence if detected early and hence improved quality of life. We report a case of bilateral symptomatic choroidal metastasis at first sign of lung carcinoma with significant improvement of vision bilaterally after palliative radiotherapy.
