[Photodynamic therapy for circumscribed choroidal hemangioma]
1Beijing Tongren Eye Center, Capital University of Medical Sciences, Beijing 100730, China.
Objective:
To investigate the safety and efficacy of photodynamic therapy in patients with circumscribed choroidal haemangioma (CCH).
Methods:
Five patients diagnosed as CCH according to ophthalmoscopy, fundus fluorescein angiography and coloured doppler imaging were treated by photodynamic therapy using verteporfin. Four of them were accompanied by serous retinal detachment extending into the macula. The range of the best-corrected visual acuity was 0.02-0.8, and the thickness of the angioma ranged from 2.5 to 5.4 mm while the base dimension was between 6.5-12.5 mm. The patients were followed up for 13 weeks to 56 weeks after photodynamic therapy.
Results:
The serous retinal detachments resolved completely and the visual acuity either improved or remained stable in all cases after once PDT, The final best-corrected visual acuity ranged from 0.2 to 0.9.
Conclusions:
PDT is effective in the management of CCH, and especially safe for the treatment of macular choroidal haemangioma. PDT can make the tumor regressed and the visual acuity preserved or improved.
