To evaluate the efficacy of reduced power photodynamic therapy (PDT) for chronic central serous chorioretinopathy (CSC).
We reviewed the medical records of seven eyes of 7 patients with chronic CSC, on who were reduced power PDT performed and followed up for more than 6 months after the treatment. They were six males and one female, and the average age was 58.0 years old. All of them were suffered from CSC for more than three months. The total PDT energy was reduced to about a half power by usage of the contact lens with 1.44 magnifying power. The visual acuity and the degrees of central macular thickness (CMT) were compared before and after the treatment. The resolution and the recurrence of serous retinal detachment (SRD) and pigment epithelial detachment (PED) were also accessed by optical coherence tomography.
The average of visual acuity before the treatment was 0.187 in logMAR. PED and/or SRD were observed in all cases. At one month after the treatment, the average of visual acuity was 0.188, and both PED and SRD were disappeared in all cases. The average of CMT was 312 micrometers before PDT and reduced to 190.6 micrometers at one month after the treatment. The average of visual acuity at 6 months after PDT was 0.023, one of CMT was 193 micrometers, and no recurrence of PED or SRD was observed in any cases.
The reduced power PDT is effective in chronic CSC to diminish the thickness of retina, extinguish both PED and SRD and suppress the recurrence of them. The good visual acuity is able to be maintained even six months after the treatment.
