          Abstract

          Background: To evaluate risk factors for the recurrence of serous macular detachment in untreated patients with central serous chorioretinopathy (CSC). Methods: Retrospective review of untreated CSC patients with a follow-up of ≧3 years. Patient demographics, visual outcome and risk factors for the recurrence of CSC were analyzed. Results: Seventy-three eyes of 73 patients were included, and the mean age was 44.6 years. At baseline, the mean logMAR best corrected visual acuity (BCVA) was 0.30. After a mean follow-up of 72 months, the mean final logMAR BCVA was 0.32. The difference between the final and baseline BCVAs was not statistically significant (p = 0.79). At the last follow-up, 9 (12.3%) eyes showed improved vision of ≧2 lines, and 12 (16.4%) showed a worsening of ≧2 lines. During follow-up, 38 (52.1%) patients experienced ≧1 episode of CSC recurrence. Multivariate Cox regression analysis showed that patients with a history of psychiatric illness (adjustment disorder and depression) were associated with an increased risk of CSC recurrence (hazard ratio = 3.5, p = 0.011). Conclusions: The long-term visual prognosis of CSC is fair without treatment, and a significant proportion of patients developed recurrence of CSC. A history of psychiatric illness is associated with an increased risk of CSC recurrence.

          Risk factors for central serous chorioretinopathy: a case-control study.

          To identify systemic factors associated with the development of central serous chorioretinopathy (CSCR). Retrospective, case-control study. 312 cases and 312 controls. By use of a multivariate analysis, the previously described risk factors, systemic steroid use (odds ratio [OR], 37.1; 95% confidence interval [CI], 6.2-221.8), and pregnancy (OR, 7.1; 95% CI, 1.0-50.7), were strongly associated with CSCR. Additional risk factors identified by this study include antibiotic use (OR, 6.2; 95% CI, 1.0-37.9), alcohol use (OR, 4.9; 95% CI, 1.5-16.3), untreated hypertension (OR, 3.3; 95% CI, 1.3-8.5), and allergic respiratory disease (OR, 2.5; 95% CI, 1.2-5.1). A wide variety of systemic factors are associated with CSCR. Prospective studies are warranted to evaluate the nature and significance of these associations further.

            Half-dose verteporfin photodynamic therapy for acute central serous chorioretinopathy: one-year results of a randomized controlled trial.

            To evaluate the efficacy of photodynamic therapy (PDT) with half-dose verteporfin for treating acute central serous chorioretinopathy (CSC). Prospective, double-masked, placebo-controlled, randomized clinical trial. Sixty-three eyes of 63 patients with acute symptomatic CSC of 3 months' duration or less were recruited. Forty-three eyes were randomized to indocyanine green angiography (ICGA)-guided PDT with half-dose (3 mg/m(2)) verteporfin and 21 eyes were randomized to placebo. Patients in the verteporfin group received an infusion of half-dose verteporfin over 8 minutes, followed by ICGA-guided PDT 10 minutes from the start of infusion. Laser was applied for 83 seconds covering the choroidal abnormalities observed in ICGA, with a maximum laser spot size of 4500 mum. The primary outcome measure was the proportion of eyes with absence of subretinal fluid at the macula at 12 months. Secondary outcome measures included changes in mean logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA), subjective symptoms, optical coherence tomography (OCT) results, central foveal thickness (CFT), and angiographic findings during the 12-month study period. Thirty-nine patients in the verteporfin group and 19 patients in the placebo group completed 12 months of follow-up. Thirty-seven (94.9%) eyes in the verteporfin group compared with 11 (57.9%) eyes in the placebo group showed absence of subretinal fluid at the macula at 12 months (P = 0.001). The mean logMAR BCVA at 12 months was significantly better in the verteporfin group compared with the placebo group: -0.05 and 0.05, respectively (P = 0.008). All 39 (100%) verteporfin-treated eyes had stable or improved vision, compared with 15 (78.9%) eyes in the placebo group (P = 0.009). The mean OCT CFT for the verteporfin group also was significantly lower compared with the placebo group at 12 months (P = 0.001). No ocular or systemic adverse event was encountered in the study. Photodynamic therapy with half-dose verteporfin is effective in treating acute symptomatic CSC, resulting in a higher proportion of patients with absence of exudative macular detachment and better visual acuity compared with placebo.

              Safety enhanced photodynamic therapy for chronic central serous chorioretinopathy: one-year results of a prospective study.

              To evaluate the efficacy of a safety enhanced photodynamic therapy (PDT) protocol with half-dose verteporfin for treating chronic central serous chorioretinopathy (CSC). Forty-eight eyes of 48 patients with symptomatic chronic CSC underwent indocyanine green angiography guided PDT with half dose (3 mg/m) verteporfin. Outcome measures included logMAR best-corrected visual acuity (BCVA), central retinal thickness, and angiographic changes during the 12-month study period. The mean CSC duration was 8.2 months (range, 3-40 months). At 12 months after PDT, the mean logMAR BCVA improved from 0.31 to 0.15 (P < 0.001). The mean improvement was 1.6 lines and 45 (95.8%) eyes had stable or improved vision. Eyes without pigment epithelial detachment (PED) had significantly greater visual improvement compared with eyes with PED (P = 0.031). Patients with CSC of 6 months or less or younger than 45 years were more likely to gain vision by two or more lines after treatment (P = 0.007 and P = 0.018, respectively). Forty (83.3%) eyes had complete resolution of serous detachment at 3 months, with 43 (89.6%) eyes at 12 months. The safety enhanced PDT protocol appeared to be beneficial for patients with chronic CSC. Further controlled study is warranted to evaluate the safety and efficacy of this treatment option.
