Subthreshold Micropulse Yellow Laser Treatment for Central Serous Chorioretinopathy

CSR is characterized by avascular focal leakage from the choriocapillaris through the retinal pigment epithelium (RPE), resulting in serous detachment of the neurosensory retina. It is usually self-limiting; in a small minority of cases chronic CSR may develop with the potential for progressive RPE atrophy and permanent visual loss. Treatment is challenging as focal laser can cause scarring and visual loss. Photodynamic therapy is not always effective. The Supra 577TM nm yellow micro pulse laser (Quantel medical) has been recently used for chronic CSR treatment. It is highly selective localizing the effect on the RPE, whilst sparing the fovea. The purpose of our study is to assess the efficacy and safety of the Supra 577TM MicroPulse (MP) laser treatment in cases of chronic and chronic recurrent central serous chorioretinopathy (cCSR) (rCSR). The aim was to document and measure the changes in the central retinal thickness (CRT) and best corrected visual acuity (BCVA) and the integrity of the fovea in a short period of time after treatment.
