AIM: To investigate the effect of micropulse diode laser photocoagulation on central serous choroidretinopathy(CSC).

METHODS: Twelve patients diagnosed with CSC by fluorescein angiography(FFA)and optic coherence tomography(OCT)examination were treated with micropulse diode laser photocoagulation. The data of visual acuity testing, ophthalmic examination, color photographs, FFA and OCT before photocoagulation and 1 week, 2 weeks, 1 month, 3 months after it were used to evaluate the effects of micropulse diode laser photocoagulation.

RESULTS: All patients' self-conscious symptom and visual acuity improved differently. Nine and eleven eyes leakage point disappeared after micropulse diode laser photocoagulation in 2 weeks and one month in FFA. Nine and eleven eyes of subretinal effusion in OCT were absorbed after laser photocoagulation in 2 weeks and one month. All cases' leakage point and subretinal effusion disappeared after 3 months. The window defect in FFA did not occur in all laser treated eyes.

CONCLUSION: The micropulse diode laser photocoagulation could shorten the course of CSC, improve the patient's visual acuity and reduce the complications.
