Late Onset Retinoblastoma Presenting with Vitreous Haemorrhage

Our work describes the management of young patients who presents with vitreous haemorrhage. It is important to note that the causes differ significantly from adults with vitreous haemorrhage. A 16-year old patient presented with vitreous haemorrhage. B-scan ultrasonography showed hypodense elements in the retina. A vascularized gelatinous mass was revealed after vitrectomy. Later the patient developed white cysts in the anterior chamber and histological findings were indicative of a retinoblastoma. The patient was enucleated and the diagnosis of retinoblastoma was confirmed. Intraocular surgery in young people with unknown retinoblastoma enhances the risk of metastasis development, orbital recurrence and death. Unexplained vitreous haemorrhage can obscure the view of a tumour but ultrasonic findings of a retinal mass calls for further imaging e.g. through MRI. The case illustrates the importance of excluding intraocular malignancy and advises a limited use of surgery in the initial examination of vitreous haemorrhage in young people.
