Abstract
Purpose: :
To evaluate the effect of micropulse 577 nm yellow laser photocoagulation in the resolution of central serous chorio-retinopathy (CSC) retinal detachment.
Methods: :
Eight patients presented with CSC for at least 12 weeks were submitted to micropulse 577 nm yellow laser photocoagulation over the retinal detachment (RD) area. The main outcome measures were best-corrected visual acuity (BCVA), resolution of subretinal fluid (retinal detachment) by spectral domain optical coherence tomography (SD-OCT) and leakage areas on fluorescein angiography (FA). Functional analysis of the macular area was performed with microperimetry. All patients were also evaluated by indocyanine angiography for documentation and differential diagnosis. Re-treatment was considered if no improvement occurred or had gotten worse after two weeks after micropulse laser.
Results: :
All subjects were male, besides one female patient that was chronic a user of corticosteroids due to kidney transplant. Age varied from 36 to 50 years old (mean of 44 years). The mean duration of CSC was 33.71 weeks (from 12 to 72) and the BCVA varied from 20/40 to 20/80. The mean follow-up period was 32,62 days (22 to 45 days). The majority of the patients (71.42%) recovered with a single laser session. All patients had complete resolution of the symptoms, subretinal fluid reabsorption, as well as reduction os leakeage areas on FA. There was also a functional improvement in microperimetry map. However the improvement of BCVA happened in 71.42%. There were no signs of laser marks on the treated areas by clinical examination or fluorescein angiography.
Conclusions: :
The results suggest that micropulse 577 nm yellow laser photocoagulation might be considered as a good and safe treatment option for central serous chorio-retinopathy.
