Objective To assess the change in the choroidal thickness of the unaffected eyes in patients with unilateral central serous chorioretinopathy (CSC). Methods Thirty eyes with unilateral idiopathic CSC and 30 age-matched normal eyes were included in this study. Choroidal thickness was evaluated from images obtained by enhanced depth image optical coherence tomography. The choroidal thicknesses of the affected eyes, unaffected eyes, and normal eyes were analyzed. Choroidal vascular dilation and hyperpermeability on indocyanine green angiography (ICGA) were analyzed and correlated with the changes in choroidal thickness. Results The mean choroidal thicknesses of the affected eyes, unaffected fellow eyes, and normal individuals were 445.58 ± 100.25, 378.35±117.44, and 266.80±55.45 lm, respectively. Compared with normal eyes, subfoveal choroidal thickness was increased significantly in the eyes with active CSC and in the unaffected fellow eyes (Po0.001 in both groups). The choroidal thickness was significantly greater in the eyes with active CSC than in the unaffected fellow eyes (P ¼ 0.003). ICGA revealed choroidal vascular hyperpermeability in 28 (93.3%) eyes with CSC and in 23 (73.3%) unaffected fellow eyes. Choroidal vascular dilation was detected in 21 (70.0%) eyes with CSC and in 18 (60.0%) unaffected fellow eyes. Conclusion Increased choroidal thickness in patients with unilateral CSC was noted not only in the affected eyes, but also in the unaffected fellow eyes. The results of this study suggest that CSC might be an essentially bilateral disorder.

BACKGROUND: To determine the prognostic factors and treatment outcomes of patients with early-stage adenocarcinoma (AdCa) of uterine cervix who underwent radical hysterectomy (RH). METHODS: Patients with early-stage squamous cell carcinoma (SCCa) of the uterine cervix who underwent RH were compared with patients with AdCa by multivariate analysis. RESULTS: A total of 1218 patients were eligible, of which 996 (81.8%) had SCCa and 222 (18.2%) had AdCa. In multivariate analysis, parametrial involvement and lymph node metastasis were significant factors for both recurrence-free survival(RFS) and overall survival (OS) of patients with AdCa, whereas age, tumour size, parametrial involvement and lymph node metastasis were significant factors for both RFS and OS of patients with SCCa. After adjusting for significant prognostic factors, patients with AdCa had significantly poorer RFS (odds ratio (OR) ¼ 2.07, 95% confidence interval (CI) ¼ 1.37 -3.12, P ¼ 0.001) and OS (OR ¼ 2.56, 95% CI ¼ 1.65 -3.96, Po0.001) than patients with SCCa. Recurrence outside the pelvis was more frequent in AdCa than in those with SCCa (75 vs 57.8%, P ¼ 0.084). CONCLUSION(S): Although RH is still acceptable for treatment of patients with AdCa, a more effective systemic adjuvant therapy is required.
