Identifying macular neovascularization (MNV) in eyes with central serous chorioretinopathy (CSC) has important implications for its management. Optical coherence tomography angiography (OCTA) is increasingly used for this purpose. Here, we systematically reviewed the literature and conducted meta-analysis to determine the diagnostic accuracy of OCTA for detecting MNV in eyes with CSC. We systematically searched the literature in 12 databases for relevant studies from database inception until 18 November 2023. Eligible studies had eyes with CSC with MNV and CSC without MNV. Index test was OCTA. Reference test was retinal dye angiography. Study selection and data extraction were performed in duplicate, and study was evaluated using the Quality Assessment of Diagnostic Accuracy Studies 2. Our main outcome of interest was the sensitivity and specificity of OCTA for detecting MNV in CSC. Pooled diagnostic test accuracy estimates were computed using MetaDTA. Of 177 records screened, seven fulfilled the eligibility criteria for our study. These studies summarized data from a total of 1061 eyes. Summary estimate sensitivity and specificity to diagnose MNV in eyes with CSC using OCTA was 92.9% (95% CI: 81.7%-97.5%) and 99.4% (95% CI: 84.1%-100.0%), respectively. The main source of bias across studies was the reference standard, as four studies used multimodal imaging including OCTA for the reference standard. OCTA alone is excellent for detecting MNV in CSC compared to retinal dye angiography or multimodal imaging. Using OCTA first before considering retinal dye angiography could potentially save an important number of retinal dye angiographies., (© 2024 Acta Ophthalmologica Scandinavica Foundation.

Purpose: Choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA) is a hallmark feature of central serous chorioretinopathy (CSC). We identified three distinct CVH phenotypes in CSC: uni-focal indistinct signs of choroidal hyperpermeability (uni-FISH) with one focal area of CVH, multiple areas of focal CVH (multi-FISH), and diffuse hyperpermeability covering most of the posterior pole (DISH). This report investigates the distribution of these phenotypes and their association with signs of disease chronicity., Methods: The CERTAIN study is a monocentric, retrospective study on consecutive CSC patients referred to a large tertiary referral centre that underwent ultra-widefield (UWF) and 55° ICGA. Two independent graders assessed CVH patterns based on mid- to late-phase UWF and 55° ICGA with a third grader acting as referee., Results: Of the 167 eyes of 91 patients included in this study, 43 (26%) showed uni-FISH, 87 (52%) multi-FISH, and 34 (20%) showed DISH based on UWF ICGA. Median age (40 vs. 45 vs. 57; p < 0.001) and logMAR visual acuity (0 vs. 0 vs. 0.1, p < 0.001) differed significantly in-between groups, as did the occurrence of cystoid retinal degeneration (PCRD; 0% vs. 1% vs. 18%, p < 0.001) or diffuse atrophic RPE alterations (DARA; 0% vs. 17% vs. 29%, p < 0.001). The same was true when grading was based on 55° ICGA., Conclusions: The CVH patterns of uni-FISH, multi-FISH, and DISH are typical of CSC. These patterns correlate with established signs of CSC chronicity. Their predictive role in treatment response and prognosis remains to be evaluated., (© 2024 The Authors.

Purpose: To explore subretinal fluid (SRF) morphology in chronic central serous chorioretinopathy (cCSC) after one session of either high-density subthreshold micropulse laser (HSML) treatment or half-dose photodynamic therapy (PDT)., Methods: We retrospectively obtained optical coherence tomography (OCT) scans from a subset of patients from a randomized controlled trial on treatment-naïve eyes with cCSC allocated to either HSML treatment or half-dose PDT. OCT scans were evaluated prior to treatment and 6-8 weeks post-treatment, where we measured maximum SRF height and width, calculated the maximum height-to-maximum width-ratio (maxHWR) and calculated the total SRF volume., Results: Forty-one eyes of 39 cCSC patients were included. SRF morphology ranged from flat to dome-shaped, quantified as maxHWR ranging between 0.02 and 0.12. SRF volume was median 0.373 μl (range: 0.010-4.425 μl) and did not correlate to maxHWR (rho = -0.004, p = 0.982). Half-dose PDT was superior to HSML treatment in complete SRF resolution (RR = 3.28, p = 0.003) and in morphological changes of SRF (Δ maximum height , p = 0.001; Δ maximum width , p < 0.001; Δ volume , p = 0.025). SRF resolved completely in 19/22 PDT-treated eyes (86%) and 5/19 HSML-treated eyes (26%). SRF volume increased in five eyes (26%) after HSML treatment, and in none of the eyes after half-dose PDT. SRF morphology at baseline did not predict treatment outcomes., Conclusion: SRF morphology changed after both HSML treatment and half-dose PDT in cCSC, with SRF disappearing in most PDT-treated patients, whereas SRF volume increased in a sizeable proportion of HSML-treated patients. Baseline SRF characteristics measured in this study were unable to predict outcomes after either HSML treatment or half-dose PDT., (© 2021 The Authors.

Purpose: To describe the characteristics and potential differences between focal and diffuse phenotypes of untreated chronic central serous chorioretinopathy (cCSC)., Methods: For this study, patients were divided in two groups. Focal leakage was defined as 1 "hot spot" of leakage, whereas diffuse leakage was defined as either > 1 hot spot or a larger area of widespread leakage on FA. Clinical characteristics were assessed at presentation. After Bonferroni correction, P values < 0.00125 were deemed statistically significant., Results: The focal leakage group included 68 eyes (53 males), and the diffuse leakage group included 105 eyes (88 males). Mean best-corrected visual acuity (BCVA) was 77.1 ± 8.1 Early Treatment of Diabetic Retinopathy Study (ETDRS) letters in the focal group and 76.0 ± 9.6 ETDRS letters in the diffuse group (p = 0.440). In the focal group, mean age was 46.9 ± 8.8 years, whereas this was 49.7 ± 8.3 years in the diffuse group (p = 0.033). Mean central foveal thickness was 107.1 ± 21.3 μm in the focal group and 106.2 ± 27.3 μm in the diffuse group (p = 0.818). Mean choroidal thickness was 407.5 ± 114.8 μm in the focal group and 419.1 ± 113.9 μm in the diffuse group (p = 0.578). In the focal group, subretinal fluid was present in the fellow eye in 16% of the patients, as compared to 29% in the diffuse group (p = 0.067)., Conclusions: In untreated cCSC patients with focal or diffuse leakage on FA, no marked differences in clinical characteristics were found. Extensive choroidal abnormalities may be present in both groups, which are presumed to lie at the basis of the development of cCSC.

Purpose: To assess ophthalmologic characteristics in patients and unaffected individuals in families with multiple members affected by central serous chorioretinopathy (CSC), both at presentation and long-term follow-up., Methods: In 103 subjects from 23 families with at least 2 affected patients with CSC per family, prospective extensive ophthalmologic examination was performed, including best-corrected visual acuity, indirect ophthalmoscopy, digital color fundus photography, optical coherence tomography, fundus autofluorescence, and fluorescein angiography imaging. From these, 24 individuals from 6 families had undergone extensive ophthalmologic examination in either 1994 or 1995 and were followed up in this study., Results: Subretinal fluid accumulation on optical coherence tomography and/or "hot spots" of leakage on fluorescein angiography indicative of CSC were detected in 45 of 103 phenotyped subjects (44%). Findings suggestive of CSC, but without the presence of subretinal fluid on optical coherence tomography and/or "hot spots" of leakage on fluorescein angiography, were observed in an additional 27 family members (26%). In 4 of 17 previously nonaffected subjects (24%) from the 24 individuals that were followed up after more than 20 years, we found more severe abnormalities., Conclusion: Extensive ophthalmologic phenotyping resulted in the detection of (suggestive) CSC in 52% of family members of patients with CSC. Genetic factors may play an important role in these specific CSC cases. Moreover, during follow-up, progressive disease can occur in a noteworthy number of patients.

Purpose: To assess the ophthalmological characteristics of asymptomatic patients with a renal transplant on chronic low-dose steroids for at least the last 2 years prior to examination., Methods: Cross-sectional study. All patients underwent an extensive ophthalmological examination., Results: Of the 37 included patients [25 male, 12 female; 59 ± 11 years (range, 38-77 years)] ophthalmological phenotyping revealed abnormalities in 22 patients (59%). Findings characteristic for (subclinical) central serous chorioretinopathy were detected in ten patients (27%), including two patients with serous subretinal fluid in the macula. An epiretinal membrane of the macula was present in six patients (16%). Mean subfoveal choroidal thickness was significantly increased in patients with ophthalmological abnormalities, in comparison with patients without abnormalities., Conclusions: Retinal abnormalities are common in the majority of renal transplant patients using chronic low-dose steroids. These retinal changes may be associated with the renal disease and/or the effect of chronic steroid use on the choroid and retina.

Purpose: To assess the efficacy of photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (cCSC), in whom subretinal fluid (SRF) was solely present outside the foveal area., Methods: In this retrospective study, 16 eyes of 15 cCSC patients who received half-dose PDT because of notable subjective visual complaints due to the presence of extrafoveal SRF, were included. An ophthalmic examination was performed before treatment, including Early Treatment Diabetic Retinopathy Study best-corrected visual acuity measurement, applanation tonometry, slit-lamp examination, and indirect ophthalmoscopy, followed by multimodal imaging, including fundus photography, fundus autofluorescence, spectral-domain optical coherence tomography (OCT), enhanced-depth imaging OCT of the choroid, fluorescein angiography, and indocyanine green angiography., Results: In 7 treated patients (47%), PDT led to a decrease in visual complaints at the first evaluation visit. At this visit, extrafoveal SRF on OCT had resolved in 14 eyes (88%), whereas a complete resolution of extrafoveal SRF had occurred in all eyes at final follow-up visit. At baseline, posterior cystoid retinal degeneration was also present in 5 eyes (31%) and this remained present at all evaluation visits in these patients. Choroidal thickness decreased statistically significantly in the treated eyes, both foveally and at the location of the maximum height of extrafoveal SRF. No complications of PDT were observed., Conclusions: Half-dose PDT treatment of cCSC patients with visual complaints due to extrafoveal SRF accumulation is a safe procedure leading to complete SRF resolution, a decrease in choroidal thickness, and a reduction in visual symptoms.
