Persistent serous retinal detachment (SRD) is a common complication of tilted disc syndrome (TDS). The purpose of this study is to evaluate the efficacy of subthreshold laser photocoagulation for SRD associated with TDS. This retrospective, single-center study included 5 eyes of 5 patients with TDS-associated SRD treated by subthreshold laser treatment. SRD was completely absorbed in 4 eyes within 4 months after initial treatment. However, it recurred in 2 eyes; one required additional laser treatment and one showed spontaneous resolution. Eventually, all 4 eyes showed complete SRD resorption. The mean visual acuities at enrollment and 1 and 3 months showed no significant differences. The mean central macular thickness showed a significant decrease at 3 months. Two eyes showed changes in fundus autofluorescence findings at the laser ablation site. However, there were no instances of laser scotoma and no laser-induced retinal scarring on color fundus photography performed at the end of treatment. In conclusion, subthreshold laser photocoagulation is an effective treatment for SRD associated with TDS. Thus, the clinical indications of subthreshold laser photocoagulation may be extended to SRD in patients with TDS.
