Atypical Retinoblastoma Presentation - A Challenge for the Treating Ophthalmologist

Retinoblastoma is the most common primary intraocular malignancy in children.1 Incidence of retinoblastoma is constant worldwide at one case per 15000–20000 live births, which corresponds to about 9000 new cases every year.2,3 It usually occurs in children under five years of age and can lead to loss of vision, and in extreme cases, death.4 The common signs of its presentation are leukocoria, strabismus, secondary glaucoma, proptosis, anterior chamber inflammatory signs and spontaneous hyphaema.1 Prognosis for vision and survival has significantly improved due to timely diagnosis and improved treatment methods.5
