Fourteen patients received overlapping spots(two to three spots) PDT,whereas eight patients received single-spot PDT. Laser was used at 50J/cm2for 83s in the overlapping-spot group and 50J/cm2for 166s in the single-spot group. Clinical examination,funduscopy,fluorescein angiography,and ultrasonography were performed at baseline and after treatment. ·RESULTS: The mean follow-up time was 28.5 ±8.0 months in the overlapping-spot group and 27.0 ±5.0 months in the single-spot group. Nine patients(64.2%) had their vision improved over two lines on the Snellen chart,and five patients showed stable visual acuity in the overlapping-spot group. The mean thickness of tumor decreased from 2.7 ±0.8mm to 1.2±0.9mm,and the mean greatest tumor linear dimension decreased from 7.4 ± 1.5mm to 4.5 ±3.5mm after treatment. In the single-spot group,two patients(25%) had their vision improved over two lines on the Snellen chart,and six patients had unchanged stable vision. The mean tumor thickness in this group decreased from 2.5±0.7mm to 1.4±1.0mm,and the mean greatest tumor linear dimension decreased from 7.2±1.3mm to 4.7±3.6mm. No significant differences in visual improvement and tumor regression were found between the two groups. ·CONCLUSION:Overlapping-spotPDTunderappropriate treatment parameters and strategies is as effective andsafe as single-spot PDT for treating symptomatic circumscribed choroidal hemangioma. Improved or stabilized visual acuity was achieved as a result of tumor regression.展开更多

She presented with a 1-month history of rapidly decreased visual acuity (VA) to counting fingers in the left eye which had no prior history of visual problem. And there was no evidence of glaucoma. At 3 months after the treatment of the standard photodynannic therapy (PDT) the VA was 20/200. For some reasons, we have no idea about the changes of tumor thickness and subretinal fluid. We confirmed the curative effect of PDT treatment for CCH because of the significantly improved VA in the bad eye.展开更多
