Transpupillary thermotherapy in the management of circumscribed choroidal hemangioma

Laser photocoagulation and various radiation therapy methods have been used in the treatment of circumscribed choroidal hemangioma that produce visual loss. Recently, transpupillary thermotherapy has been employed in the management of choroidal hemangioma. Thirty-six cases of choroidal hemangioma treated with transpupillary thermotherapy are reviewed. Twenty-eight cases were reported in the literature and 10 cases were managed by the author. Transpupillary thermotherapy has been used as a primary treatment (36 cases) or secondary treatment (2 cases) for choroidal hemangioma. The goal of transpupillary thermotherapy is to achieve resolution of exudative detachment of the fovea and improvement of vision. In all eyes the foveal detachment subsided. In 26 eyes having pretreatment visual acuity greater than or equal to0.05 (20/400), the visual acuity increased in 20 (77%) eyes and remained unchanged in 6 (23%) eyes. After transpupillary thermotherapy, 16 (42%) cases showed complete regression, 20 (53%) demonstrated partial regression, and in 2 (5%) there was no change in tumor thickness at follow-ups ranging from 2 to 44 months. Complications of transpupillary thermotherapy of choroidal hemangioma included cystoid macular edema (3 eyes), preretinal fibrosis (2 eyes), focal iris atrophy (3 eyes), and retinal vascular occlusion (I eye). Although the follow-up in many studies is limited, transpupillary thermotherapy has not been associated with any significant complications.
