Choroidal haemangioma (CH) is a benign vascular tumour. CH that produces visual symptoms due to subretinal fluid has been treated with cryotherapy, diathermy, photocoagulation, photodynamic therapy (PDT), transpupillary thermotherapy (TTT) and various radiation therapies. However, extensive exudative retinal detachment is challenging to treat. Previous reports utilising gamma knife radiosurgery (GKR) in CHs are scarce.1 2 We present our results of GKR on CH with extensive exudative retinal detachment (RD).

Methods

The medical records of three consecutive CH patients with decreased visual acuity due to extensive exudative RD involving more than two quadrants, treated with GKR, were retrospectively reviewed. GKR was performed as a secondary treatment after the aggravation of exudative RD following a single session of transpupillary thermotherapy (TTT).

Results

Table 1 lists the basic characteristics of the patients. The mean age of the patients was 38.3 years …
