Background/Objectives: Central serous chorioretinopathy (CSCR) is a common retinopathy that can present with other concurrent diseases; thus, further research into the prevalence of other ocular comorbidities in eyes with CSCR is required. Methods: This retrospective, multicentric, cross-sectional observational study reviewed the charts of 9157 patients. Of them, 579 (6.32%) patients and 766 eyes had an additional ocular comorbidity, in addition to CSCR, in at least one subject eye. Results: The baseline best-corrected visual acuity (BCVA) of the subjects eyes was 0.49 ± 0.36 logMAR. The average BCVA of subject eyes with coexisting macular diseases was 0.50 logMAR, while the corresponding BCVA of subject eyes with coexisting peripheral disease was 0.55 logMAR. The most prevalent coexisting macular diseases were non-proliferative diabetic retinopathy (26.8%), non-exudative age-related macular degeneration (AMD) (7.6%) and hypertensive retinopathy (3.0%). The most prevalent coexisting non-macular diseases were lattice degeneration (8.9%), optic atrophy (5.1%), rhegmatogenous retinal detachment (1.70%) and optic disc pit (1.7%). The odds of having a comorbid disease in the same eye as CSCR were statistically significant for branch retinal vein occlusion (OR 11.56, p-value = 0.02) and non-exudative AMD (OR 2.06; p-value = 0.01); additionally, there was a trend towards significance for idiopathic polypoidal choroidal vasculopathy (OR 4.43; p-value = 0.05) when compared to the eyes without CSCR. Conclusions: Certain diseases are more likely to coexist in eyes with CSCR. Additionally, eyes with CSCR may have statistically significant odds of certain diseases when compared to eyes without CSCR. Full article

Background/Objectives: The aim of this study was to evaluate the choroidal vascular response using optical coherence tomography (OCT) in patients with chronic central serous chorioretinopathy (CSCR) during transient increases in blood pressure. Methods: This observational, case–control study enrolled chronic CSCR patients and age-matched healthy controls. OCT scans of the macula were performed at rest and during hand-grip (HG) isometric exercise. Mean ocular perfusion pressure (MOPP) and subfoveal choroidal thickness (SCT) were measured at baseline and during stress. Quantitative OCT assessment included the bright area (BA, stroma), dark area (DA, vascular lumen), and total choroidal area (CA). The choroidal vascularity index (CVI) was calculated as DA/CA to assess vascular response to stress. A comparative analysis between CSCR patients and controls was conducted. Conclusions: MOPP was significantly higher (p = 0.008) at baseline in CSCR patients and further increased under stress compared to controls. SCT and CA were both significantly higher in CSCR patients than in healthy subjects at rest and under stress (p < 0.001), but no change occurred after HG. A significant decrease in CVI (p = 0.005) was noted in controls under stress, but not in CSCR patients. Additionally, a negative correlation between CVI and MOPP was found in healthy subjects (−0.648; p = 0.043). The study demonstrated a choroidal vasoconstrictive response to stress in healthy subjects, as evidenced by a decrease in CVI, but not in CSCR patients. This suggests that CSCR patients may experience impaired choroidal blood flow regulation, resulting in potentially higher perfusion pressures during stress without compensatory vasoconstriction, potentially affecting the choriocapillaris.

Preeclampsia is a pregnancy-specific syndrome characterized by hypertension and proteinuria. We retrospectively investigated the clinical features, including choroidal layer thickness and luminal area to stromal area ratio, in a case series of preeclampsia with serous retinal detachment (SRD). The subjects were pregnant women with SRD during hospitalization for preeclampsia from October 2014 to June 2021. Based on medical records, affected eyes, time of onset, fundus examination findings, and subfoveal choroidal thickness (SCT), the choroidal layer thickness and choroidal vascular index (CVI) in each patient was examined. Thirteen eyes from seven patients (mean age 30.7 ± 4.7 years) were included in the study. In all cases, SRD improved without topical ocular treatment. The mean SCT at the initial visit was 424.4 ± 70.5 μm, and all patients had choroidal thickening, which significantly decreased to 286.0 ± 57.9 μm (p < 0.01) at the last visit. The mean choroidal inner layer was 162.7 ± 69.4 μm at the initial visit and 122.3 ± 35.5 μm at the final follow-up visit (p = 0.06), showing no significant difference; however, the mean choroidal outer layer was 261.7 ± 47.6 μm at the initial visit and 163.7 ± 37.1 μm at the final follow-up visit (p < 0.01), thus showing a significant decrease. The mean CVI was 67.2 ± 1.3% at the initial visit, yet it had significantly decreased to 65.4 ± 1.1% (p < 0.01) at the final follow-up visit. The findings of this study show that SRD with preeclampsia is associated with increased thickening of the choroidal outer layer, especially in the choroidal luminal area. Full article

With the promotion of mass COVID-19 vaccination in the elimination of the SARS-CoV-2 pandemic, new side effects, including ocular complications, are emerging. In this study, we report on a 62-year-old Chinese man who developed Vogt–Koyanagi–Harada (VKH) disease six days after his third dose of an inactivated COVID-19 vaccine, with a preceding severe headache and tinnitus. His medical history included tuberculosis 20 years prior and hypertension. Systemic prednisone was administered, resulting in completely relieved inflammation and improved visual acuity. Another three and a half months later, the visual acuity of his right eye slightly decreased due to complicated central serous chorioretinopathy (CSC) disease. By gradually replacing prednisone with cyclosporine within 2 months, the subretinal fluid was completely absorbed at the last visit. Steroid-related CSC during the treatment course of VKH disease after COVID-19 vaccination has never been reported before. By reviewing relative literature, we discuss the mechanism of CSC onset in our case and the potential therapeutic strategies. Complicated CSC may develop in the eyes with vaccine-related VKH after steroid treatment. Ophthalmologists should be aware of this condition, carefully distinguish complicated CSC with inflammation relapse, and adjust the medication in a timely manner. Full article

We evaluated the effect of intravitreal bevacizumab injection (IVB) on choroidal thickness, and studied its association with the therapeutic response in chronic central serous chorioretinopathy (CSC). The clinical features of 78 eyes with chronic CSC treated with IVB from October 2014 to June 2020 were retrospectively evaluated. Visual acuity (VA), central retinal thickness (CRT), and sub-foveal choroidal thickness (SFCT) were analyzed at baseline, 1 month following initial IVB, and the last follow-up examination. Cases showing complete recovery (resolved eyes; n = 60) were compared with those with persistent subretinal fluid (refractory eyes; n = 18). The relationship between the potential risk factors and subretinal fluid resolution was examined using logistic regression. SFCT was significantly decreased along with the CRT following IVB at the resolved state. SFCT reduction following 1 month of IVB was notably greater in the resolved eyes. The association of refractory eyes with hypertension (p = 0.003) and a thinner baseline SFCT (p = 0.024) was significant. In most of the patients with chronic CSC, VA and CRT remarkably improved following treatment with IVB. Early changes in the SFCT following IVB were associated with the therapeutic response. Patients with hypertension and a thinner baseline SFCT could be unresponsive to IVB. Full article
