Risk Factors and Outcomes of Choroidal Neovascularization Secondary to Central Serous Chorioretinopathy.

ABSTRACT: We identified clinical characteristics and risk factors of choroidal neovascularization (CNV) in eyes with prior episode of central serous chorioretinopathy (CSC). This retrospective case-control study included those initially diagnosed with CSC and developed CNV secondarily (Group 1, n?=?16), those diagnosed with CNV in eyes of previous putative CSC (Group 2, n?=?14), and those initially diagnosed with CSC, and did not develop CNV secondarily, as a control group for Group 1 (Group 3, n?=?250). Clinical characteristics including treatment outcomes were assessed. Demographics and multimodal imaging at the time of CSC diagnosis of secondary CNV were compared between the groups to identify risk factors. Duration from diagnosis of CSC to development of CNV in Group 1 was 40.2?±?42.0 months. Classic CNV was noted in 23 (76.7%) eyes. After treatment with intravitreal antiangiogenics with average of 4.9 times, visual acuity improved in Group 1 and Group 2 (p?=?0.002). Multivariate analysis revealed that systemic hypertension, pigmentary changes, and double layer sign were associated with development of CNV secondary to CSC (p?

Project description:PurposeThis study evaluated changes in choroidal vascularity after half-fluence photodynamic therapy (HF-PDT) in patients with central serous chorioretinopathy (CSC) using swept-source optical coherence tomography (SS-OCT) en face imaging.MethodsThis retrospective comparative case series included 50 eyes of 25 patients with unilateral CSC who underwent HF-PDT and 50 age-and sex-matched normal healthy control eyes. En face SS-OCT images of the choriocapillaris, Sattler's layer, and Haller's layer were converted into binary images. The vascular proportions were defined as the percentage of the area of vascular lumen against the area of the 3.0-mm-diameter circular area. The main outcome measures were the vascular proportions before HF-PDT and at 6 weeks, 6 months, and 12 months after HF-PDT.ResultsAt baseline, the vascular proportions in the CSC eyes were significantly greater than those in the control eyes in all layers (choriocapillaris: 51.8% ± 15.5% vs. 41.3 ± 18.7%, P = 0.018; Sattler's: 58.6% ± 13.4% vs. 49.7% ± 15.7%, P = 0.017; Haller's: 65.3% ± 15.3% vs. 53.0% ± 13.4%, P = 0.001). In the CSC eyes, the vascular proportion in the choriocapillaris significantly decreased at 6 weeks (36.6% ± 16.9%, P < 0.001), 6 months (34.0% ± 12.3%, P < 0.001), and 12 months (34.8% ± 17.6%, P < 0.001) after HF-PDT compared with baseline. The vascular proportions in Sattler's and Haller's layers did not show a significant decrease at 6 weeks (Sattler's: 49.7% ± 17.3%, P = 0.052 and Haller's: 58.3% ± 12.9%, P = 0.558) but decreased significantly at 6 months (Sattler's: 48.9% ± 12.4%, P < 0.001 and Haller's: 57.7% ± 15.7%, P = 0.027) and 12 months after HF-PDT from the baseline values (Sattler's: 45.8% ± 10.4%, P < 0.001 and Haller's: 56.8% ± 15.7%, P < 0.001).ConclusionAfter HF-PDT, the choriocapillaris showed the earliest decrease in vascular proportion of en face images, Sattler's and Haller's layers showed later decreases. The temporal differences in the response of each layer may reflect the pathophysiology of CSC and the therapeutic mechanism of HF-PDT.
