Microperimetric Evaluation After Half-dose Photodynamic Therapy for Chronic Central Serous Chorioretinopathy

The best-corrected visual acuity (BCVA), macular sensitivity, and fixation stability were evaluated at the baseline and at 1, 3, 6, and 12 months after the half-dose photodynamic therapy. The macular sensitivity and fixation stability were determined by MP-1 microperimetry (Nidek, Vigonza, Italy). The researchers analysed whether the BCVA and retinal sensitivity significantly improved or not. And if yes, the researchers were interested at which period after treatment the significant improvement was found. Also, the researchers investigated which improved first, BCVA or retinal sensitivity.
