We investigate retinal layer thickness and capillary vessel density (VD) in the patients with central serous chorioretinopathy (CSC) who recovered spontaneously and evaluate the correlation between the changes in these values and visual outcomes using swept-source optical coherence tomography (SS-OCT) and OCT angiography (OCTA). This retrospective case–control study included 34 eyes of 34 patients with spontaneously resolved acute CSC. The changes in retinal layer thickness and capillary VD were examined using SS-OCT and OCTA after complete resolution of subretinal fluid (SRF). The fellow eyes and 34 healthy eyes were used as controls. In the eyes with CSC, the outer retinal layer was significantly thinner than in the eyes of fellow and healthy controls. The foveal avascular zone area and VDs in the superficial and deep capillary plexus in the eyes with CSC were not significantly different from those in the eyes of fellow and healthy controls. The VD of the choriocapillaris in the eyes with CSC was significantly lower than that in the eyes of fellow and healthy controls. Correlation analyses revealed that the outer retinal layer thickness and initial visual acuity were positively correlated with the final visual acuity. Furthermore, the initial SRF area and height were negatively correlated with the outer retinal layer thickness after SRF resolution. Attenuation of outer retinal layer thickness and decreased VD of the choriocapillaris were observed in the eyes with spontaneously resolved acute CSC. The outer retinal layer thickness could be an important visual predictor of CSC.

Abstract Purpose To evaluate the fovea in nanophthalmic eyes using spectral domain optical coherence tomography (SD-OCT) and OCT angiography (OCTA), and to investigate the relationship between the macular microstructure and visual acuity. Methods This is a retrospective case series of five nanophthalmic patients. The foveal avascular zone (FAZ) area was measured in superficial and deep vascular layers with OCTA. The thickness of the inner retinal layer (IRL) was measured with SD-OCT. The ratio of the foveal and parafoveal IRL thickness (fIRL/pIRL ratio) was calculated. The relationship between these parameters and visual acuity was then investigated. Results Eight eyes were identified as nanophthalmic with a mean axial length of 17.19 ± 1.44 mm (range: 15.71 to 19.88 mm). The mean best-corrected visual acuity (BCVA) in the logarithm of the minimum angle of resolution (logMAR) was 0.12 ± 0.18 (range: − 0.18 to 0.40). OCTA showed that FAZs were either absent or undeveloped in the superficial and deep capillary plexuses. Two patients did not show any visual impairments despite small FAZ and a shallow foveal depression. Although the BCVA was significantly correlated with the deep FAZ size, it did not correlate with the superficial FAZ size, axial length, or fIRL/pIRL ratio. However, the refractive error, axial length, and deep FAZ size were all significantly correlated with the fIRL/pIRL ratio. Conclusions The FAZs were commonly found to be small in the superficial and deep capillary plexuses. Although the deep FAZ size correlated with visual acuity, it is unclear whether the retinal microstructure and the FAZ size are responsible for the visual impairments observed in the same individuals.

Purpose: This work aims to present treatment and long-term follow-up of a 31-year-old woman with dermatomyositis who presented with hemorrhagic retinal vasculitis and macular edema. Methods: A retrospective case report is presented. Results: A 31-year-old woman with dermatomyositis treated with systemic immunosuppression was evaluated for acute, reduced vision. Best-corrected visual acuity was hand motion in the right eye and 20/200 in the left eye. Fundus examination revealed diffuse intraretinal hemorrhages, cotton-wool spots, and vascular sheathing with a frosted branch angiitis–like appearance. Optical coherence tomography revealed significant macular edema and subretinal fluid that quickly resolved after admission and treatment with intravenous steroids. Multimodal imaging at 7-year follow-up disclosed long-term sequelae including peripheral nonperfusion and retinal neovascularization. Conclusions: When vasculitis associated with dermatomyositis is treated aggressively with intravenous steroids at initial presentation, good visual acuity outcomes can be achieved, but long-term consequences of retinal nonperfusion and neovascularization persist.

AbstractBiomarker tests of Alzheimer’s disease (AD) are invasive and expensive. Recent developments in optical coherence tomography (OCT) and OCT angiography (OCTA) have enabled noninvasive, cost-effective characterization of retinal layer vasculature and thickness. Using OCTA and OCT, we characterized retinal microvascular changes in the mild cognitive impairment (MCI) stage of AD and assessed their correlation with structural changes in each retinal neuronal layer. We also evaluated the effect of the APOE-ε4 genotype on retinal microvasculature and layer thickness. Retinal layer thickness did not differ between MCI patients (40 eyes) and controls (37 eyes, all p > 0.05). MCI patients had lower vessel density (VD) (p = 0.003) of the superficial capillary plexus (SCP) and larger foveal avascular zone area (p = 0.01) of the deep capillary plexus (DCP) than those of controls. VD of the SCP correlated with the ganglion cell layer (r = 0.358, p = 0.03) and inner plexiform layer thickness (r = 0.437, p = 0.007) in MCI patients. APOE-ε4-carrying MCI patients had a lower VD of the DCP than non-carriers (p = 0.03). In conclusion, retinal microvasculature was reduced in patients with AD-associated MCI, but retinal thickness was not changed; these changes might be affected by the APOE genotype. OCTA of the retinal microvasculature may be useful to detect vascular changes in AD.

AbstractWe evaluated postoperative retinal thickness in pediatric and juvenile craniopharyngioma (CP) patients with chiasmal compression using optical coherence tomography (OCT) auto-segmentation. We included 18 eyes of 18 pediatric or juvenile patients with CP and 20 healthy controls. Each thickness of the macular retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer, outer plexiform layer, outer nuclear layer, and photoreceptor layer was compared between the CP patients and healthy controls. There was significant thinning in the macular RNFL (estimates [μm], superior, − 10.68; inferior, − 7.24; nasal, − 14.22), all quadrants of GCL (superior, − 16.53; inferior, − 14.37; nasal, − 24.34; temporal, − 9.91) and IPL (superior, − 11.45; inferior, − 9.76; nasal, − 15.25; temporal, − 4.97) in pediatric and juvenile CP patients postoperatively compared to healthy control eyes after adjusting for age and refractive errors. Thickness reduction in the average and nasal quadrant of RNFL, GCL, and IPL was associated with peripapillary RNFL thickness, and reduced nasal quadrant GCL and IPL thicknesses were associated with postoperative visual field defects. In pediatric and juvenile patients with CP, decreased inner retinal layer thickness following chiasmal compression was observed. The changes in retinal structures were closely related to peripapillary RNFL thinning and functional outcomes.

Purpose We investigated the correlation between visual acuity (VA) and individual retinal layer thickness in the foveal, parafoveal, and perifoveal regions of patients with an idiopathic epiretinal membrane (ERM). Methods One hundred and five subjects presenting with unilateral idiopathic ERM were included in this study. We segmented each patient’s optical coherence tomography (OCT) image into seven layers and calculated the mean layer thickness in the foveal, parafoveal, and perifoveal regions using the Iowa Reference Algorithm. In 105 patients with ERM, we detected correlations between their macular regions’ individual retinal layer thickness and their best corrected VA. Thirty-one of the 105 patients with ERM underwent vitrectomy and completed six months of follow-up. We then compared the 31 surgical patients’ preoperative and postoperative individual retinal layer thickness in each macular region. Additionally, the association between preoperative individual retinal layer thickness in each macular region and VA six months post-surgery in patients with ≥ two Snellen lines of visual improvement was determined. Results Multiple linear regression analysis showed that the inner nuclear layer (INL) thickness in the foveal, parafoveal, and perifoveal region were all associated with VA in the 105 patients (R2 = 0.344, P < 0.001; R2 = 0.427, P < 0.001; and R2 = 0.340, P < 0.001, respectively). Thirty-one surgical patients 6 months post-surgery showed significantly decreased thicknesses (P ≤ 0.012) of the foveal INL, inner plexiform layer (IPL), and outer nuclear layer (ONL); the parafoveal retina nerve fiber layer (RNFL), IPL, INL, and ONL; and the perifoveal RNFL, IPL, INL, ganglion cell layer (GCL), outer plexiform layer (OPL), and photoreceptor layer (PRL). We found a weak correlation between postoperative VA and preoperative foveal and perifoveal RNFL thickness (r = 0.404 and r = 0.359, respectively), and a moderate correlation between postoperative VA and preoperative foveal and parafoveal INL thickness (r = 0.529 and r = 0.583, respectively) in the 31 surgical patients (P ≤ 0.047). The preoperative INL thickness in the foveal, parafoveal, and perifoveal regions showed a moderate to strong correlation (r = 0.507, 0.644, and 0.548, respectively), with postoperative VA in patients with ≥ 2 lines of visual improvement (P ≤ 0.038). Conclusion We detected a correlation between retinal damage and VA in the parafoveal, perifoveal, and foveal regions. Our results suggest that INL thickness in all macular regions may be a prognostic factor for postoperative VA in ERM patients.

Abstract Background: This study aimed to investigate the relationship between early changes in retinal layer thickness and thiol–disulfide homeostasis in patients with type II diabetes mellitus (T2DM).Materials-Methods: There were 69 patients with T2DM (61 patients without retinopathy, 8 patients with retinopathy) and 21 healthy controls. In patients without retinopathy, 31 of the patients had a disease duration under 10 years, 30 of the patients had a disease duration over 10 years. Retinal layer thickness of the right eye was measured using Spectral Domain Optical Coherence Tomography. Results: Patients with T2DM and healthy controls had mean ages of 48.40 ± 8.25 years and 45.94 ± 7.32 years, respectively. The ganglion cell layer and retinal pigment epithelium thicknesses were significantly lesser in patients without diabetic retinopathy than those in the control group. In patients without diabetic retinopathy and with a disease duration of under 10 years, there was a negative correlation between the retinal nerve fiber layer thickness (µm) and disulphide/total thiol ratio, between the inner nuclear layer thickness (µm) and disulphide/native thiol ratio as well as disulphide/total thiol ratio (r= −0.376, p= 0.037; r= −0.356, p= 0.050; r= −0.380, p= 0.035, respectively) and positive correlation between the INL thickness (µm) and native thiol/total thiol ratio (r= 0.359, p= 0.047).Conclusion: Early changes in retinal layers in patients with DM were associated with thiol–disulfide homeostasis. Administration of therapeutic supplements may aid in the management of low thiol concentrations; this increases the importance of the study findings.

The aim of the study was to evaluate the results of nailfold videocapillaroscopy (NVC) in patients with central serous chorioretinopathy (CSC) and their correlation with different functional, morphological features and general risk factors. Material and methods: The examined group included 59 CSC patients (14 F, 45 M, mean age 47.2 ± 9.4) and 53 healthy controls (13 F, 40 M, mean age 46 ± 11.5). The NVC was qualified as a normal or abnormal pattern. In the CSC group, the ophthalmoscopy, angio-Optical Coherence Tomography (OCT-A), OCT and microperimetry were performed. The medical history regarding CSC, chronic general disorders and known risk factors was recorded. Results: In the CSC group an abnormal NVC pattern was more common (33.88% CSC vs. 7.54%, p < 0.001). Dilated apical part of capillaries, microaneurysmal dilatation, megacapillaries, fresh microhaemorrhages, bizarre and broken capillaries were observed only in CSC patients. Dilation of capillaries (47.56% vs. 13.21%, p = 0.004), ramified capillaries and neoangiogenesis (38.98% vs. 5.66%, p < 0.001), glomerular loops (32.20% vs. 1.88% p < 0.001) were more frequent in the CSC group. Conclusions: The presence of various NVC abnormalities confirms microvascular involvement in CSC pathogenesis. The results correlate with visual acuity, microperimetry, OCT data and stress. The NVC technique may play a useful diagnostic and prognostic role in CSC.

Chronic Central Serous Chorioretinopathy

AimsTo investigate the lowest effective fluence rate of photodynamic therapy (PDT) for treating chronic central serous chorioretinopathy (CSC).MethodsFifty-one eyes of 51 patients with chronic CSC were randomly treated with 30% (n=15), 40% (n=16) or 50% (n=17) of the standard-fluence rate of PDT and followed up for 12 months. The success rate, recurrence rate, mean best-corrected visual acuity (BCVA), central foveal thickness (CFT), subfoveal choroidal thickness (SFCT), integrity of the outer retinal layer and complications were evaluated at baseline and at the follow-up periods after PDT.ResultsThe rate of complete subretinal fluid (SRF) resolution in the 30%-fluence, 40%-fluence and 50%-fluence groups was 60.0%, 81.2% and 100.0%, respectively, at 3 months (p=0.009), and 80.0%, 94.0% and 100.0%, respectively, at 12 months (p=0.06). The recurrence rate in the 50%-fluence group was lower than that in the 30%- and 40%-fluence groups at 12 months (30% vs 50%, 40% vs 50%; p=0.002, p=0.030, respectively (log-rank test)). The mean BCVA improved significantly 12 months after PDT only in the 40%- and 50%-fluence groups (p=0.005, p=0.003, respectively). Mean CFT and SFCT decreased significantly at 12 months in the three groups. The rate of complications did not differ significantly among the three groups.ConclusionsA 50%-fluence rate of PDT seems to be the most effective for treating chronic CSC, considering the low recurrence rate and high rate of complete SRF resolution, compared with other low-fluence PDT.Trial registration numberNCT01630863.

A Prospective Study

Abstract Background Increased mineralocorticoid activity is one of the plausible causes of chronic central serous chorioretinopathy (CSCR) and mineralocorticoid inhibitors such as eplerenone have been investigated as its potential therapy. This study investigates the short-term safety and efficacy of oral eplerenone in patients with chronic CSCR. Patients and methods Prospective study of 13 eyes of 13 patients with the diagnosis of chronic CSCR. All patients received eplerenone 50 mg/day for 4 weeks. Enhanced depth imaging optical coherence tomography (OCT) was obtained. Best corrected visual acuity (BCVA), and OCT parameters including sub retinal fluid (SRF), choroidal thickness (CT) and central macular thickness (CMT), were measured manually. Results The mean SRF height decreased slightly at 1-month follow-up as compared to baseline, but the change was not statistically significant (94.18 ± 17.53 vs. 113.15 ± 18.69; p = 0.08). Subfoveal CT and CMT was significantly reduced as compared to baseline (6.6% [p = 0.002] and 7.05% [p = 0.04], respectively). The BCVA did not change significantly (20/28 vs. 20/30 [p = 0.16]). Conclusion This study suggests that oral eplerenone may be used as a safe and potentially effective treatment in chronic CSCR, however there are minimal short-term effects on subretinal fluid or visual acuity therefore therapeutic trials longer than one month are necessary to test its benefits.
