RESUMEN
Choroidal haemangioma is a benign tumour with visual acuity diminution due to subretinal fluid accumulation. There are many modalities of treatment of this visually disabling syndrome, some of them being argon laser photocoagulation, cryotherapy, external beam irradiation, proton beam radiotherapy, episcleral plaque radiotherapy and transpupillary thermotherapy. Another new modality of treatment with remarkable success rate is photodynamic therapy. In this modality a photosensitiser is injected intravenously followed by irradiation of a specific wave length for a specified time period. The photosensitiser concentrates within the vascular channels and after irradiation these channels are irreversibly obliterated. A 62 years old female patient of choroidal haemangioma, who presented in eye outpatient department was treated with the standard protocol used for photodynamic therapy. On follow-up of this patient it was found that there was improvement in the visual acuity from 6/12 in the left eye (affected eye) to 6/9. Not only was there an improvement in the visual acuity but there was anatomical improvement too as was evident by regressed cystoid macular oedema and circumscribed choroidal haemangioma. After six months of follow-up there was no leakage of dye with digital fluorescein angiography and indocyanine green.
