Low power transpupillary thermotherapy with retrobulbar injection of triamcinolone acetonide for central exudative chorioretino- pathy

AIM: To observe the clinical effect of low power transpupillary thermotherapy(TTT)with retrobulbar injection of triamcinolone acetonide(TA)for central exudative chorioretinopathy(CEC).METHODS: Fourteen eyes with idiopathic choroidal neovascularization were treated with retrobulbar injection of TA and performed by low power TTT after one week. Laser parameters were as follows: spot diameter 0.8-3.0mm, low power 120-360mW, time 60 seconds. By 3 to 12 months of follow-up, visual acuity, ophthalmoscope, fundus fluorescein angiography(FFA)and optical coherence tomography(OCT)were used to observe the curative effects.RESULTS: Visual acuity were improved in 5 eyes(36%), remained stable in 8 eyes(57%)and declined in 1 eye(7%)after treatment. The macular hemorrhage and exudation were reduced significantly in 12 eyes. FFA showed that the fluorescein leakage ceased or decreased in 7 eyes, unchanged in 5 eyes, and enlarged in 2 eyes. The macular edema of 12 eyes in OCT was reduced unequally.CONCLUSION: Low power TTT combined with retrobulbar injection of TA shows good therapeutic effect on CEC.
