To document clinical pattern of retinoblastoma in Pakistani population. This retrospective study, which was conducted at Department of Ophthalmology, Dow University of Health Sciences, Karachi, reviewed clinical records of patients with retinoblastoma from 1997 to 2012. Staging of disease was done by referring to retinal diagrams, RetCam images, and first magnetic resonance imaging. Ophthalmic notes, imaging reports and histopathology reports of enucleated eyes established optic nerve involvement. SPSS 21 was used for statistical analysis. Clinical records of 295 patients with retinoblastoma in 403 eyes were reviewed, and male to female ratio was 1.3:1. Retinoblastoma was bilateral in 106(35.93%) patients, while 118(40%) patients had hereditary pattern. Mean age at presentation was 35.98+27.63 months, while mean follow-up was 3±2 months. Leucokoria was the most common presenting feature 173(58.64%) followed by proptosis 72(24.41%). Optic nerve involvement was seen on magnetic resonance imaging or histopathology in 81(20.10%) eyes. Distant metastasis was noted in 32(10.85%) patients on first presentation. Chemotherapy with or without adjuvant treatment was given to 238(80.68%) patients. Enucleation and exentration were performed in 164(40.69%) and 12(2.98%) eyes, respectively. Most common presenting symptom was leucokoria followed by proptosis.
