Abstract:
Capillary haemangiomas occurring on or adjacent to the optic disc pose unique therapeutic problems. Their natural history is highly variable, but has a propensity to lead to the development of progressive exudate with marked deterioration in visual acuity, often culminating in retinal detachment and vitreal haemorrhages. On reviewing the literature, no therapeutic modality has demonstrated an efficacy in treating the lesion and providing an acceptable visual acuity result. A case of a 61-year-old man with a left-sided juxtapapillary capillary haemangioma treated with verteporfin photodynamic therapy is described. The patient's visual acuity improved from 6/36 to 6/12 initially, with an appreciable reduction in exudate and lesion size. Subsequent treatments failed to eradicate the lesion, with visual acuity stabilizing at 6/60. With larger cohorts of patients and variable treatment parameters, the true efficacy of photodynamic therapy to treat these lesions may be determined.
