Slit-lamp photographs of selected study patients showing different morphological features of iris melanoma. A Flat, weakly pigmented iris melanoma with a small ectropion uveae. B Dome-shaped, markedly pigmented iris melanoma with an irregular surface. C Nodular, moderately pigmented iris melanoma. D Ring-shaped, markedly pigmented iris melanoma visible temporally and inferiorly. Gonioscopically, a multinodular pigmented mass was seen in the chamber angle from the 2.30 to 11 o’clock position. E Diffuse iris melanoma with multiple pigmented areas. F Amelanotic, vascularised iris melanoma. G Tapioca iris melanoma with multiple small, amelanotic nodules on the surface. H Large iris melanoma leading to pupillary distortion and ectropion uveae
