About

MICROPULSE study aims to evaluate the efficacy of navigated microsecond laser (nMSL) for chronic central serous chorioretinopathy (CSCR).

Full description

Chronic central serous chorioretinopathy (CSCR) is characterized by persistent subretinal fluid (SRF) and extensive outer retinal damage on optical coherence tomography (OCT). In the last years several treatment modalities for chronic CSCR have been investigated. These treatments have included pharmacologic therapy, photodynamic therapy (PDT) and microsecond laser.

PDT is the main treatment for CSCR, especially for chronic CSCR. But the efficacy of PDT is variable and could be associated with various complications such as retinal pigment epithelium (RPE) atrophy. Furthermore other limitations of PDT are unavailability and high cost.

Recently some studies have suggested an efficacy of micropulse laser in chronic CSCR, with stabilization of visual acuity, improvement in retinal sensitivity and without any complications.

The present study aims to evaluate the efficacy of a treatment by guided micropulse laser in the management of chronic CSCR. The efficacity will be evaluated 6 weeks and 3 months after the treatment on anatomical outcomes (central macular thickness in microns)
