AB A 44-year-old man presented with complaints of pain and discomfort in his left eye (OS). On examination, he had bare perception of light in OS and had a diffuse pigmented mass lesion in the nasal quadrant of the bulbar conjunctiva, associated with neovascularisation of the iris and iridocyclitis, with no fundus view. Intraocular pressure OS was 40 mm Hg. B-scan ultrasonography OS revealed an intraocular mass with thickened sclerochoroidal complex. A clinical diagnosis of OS ciliochoroidal melanoma with extraocular extension was made. He underwent OS extended enucleation with implant. Histopathological examination confirmed the diagnosis of ciliochoroidal melanoma with tumour extension into the optic nerve posteriorly and the extrascleral tissues anteriorly. There was no evidence of systemic metastasis. Even in a case of non-juxtapapillary uveal melanoma, poor vision and high intraocular pressure are clinical indicators of optic nerve tumour invasion.
