MINERALOCORTICOID RECEPTOR ANTAGONIST TREATMENT IN BILATERAL CHRONIC CENTRAL SEROUS CHORIORETINOPATHY: A COMPARATIVE STUDY OF EXUDATIVE AND NONEXUDATIVE FELLOW EYES

Purpose: To evaluate the macular thickness, choroidal thickness, and visual acuity changes in eyes of patients with bilateral chronic central serous chorioretinopathy during eplerenone treatment. Methods: This prospective clinical trial was conducted on patients with bilateral chronic central serous chorioretinopathy, who had subretinal fluid (SRF) in 1 eye. Twenty-eight patients were treated with 50 mg/day of oral eplerenone for 3 months and were observed for another 3 months. Twenty-eight eyes with SRF were compared with the 28 fellow eyes with pachychoroid pigment epitheliopathy. Results: The central macular and choroidal thickness showed a significant decrease (P < 0.005) at 3 months in all eyes, but change in choroidal thickness was smaller in nonexudative fellow eyes (P > 0.05 at 6 months). In the exudative eyes, the decrease in choroidal thickness showed a significant correlation with the resolution of SRF (P < 0.001). Visual acuity remained stable in all eyes, with significant improvement only in exudative eyes at 6 months (P < 0.005). Baseline choroidal thickness was a significant positive predictor for SRF decrease (P = 0.003). Conclusion: Patients with chronic central serous chorioretinopathy can safely be treated with eplerenone as it can reverse choroidal vasodilation with an accompanying resolution of the SRF and improvement in visual acuity. These beneficial therapeutic effects are more pronounced in the exudative eyes.

Optical Coherence Tomography Features of POEMS Syndrome and Castleman Disease-associated Papillopathy

Abstract Purpose: To report ocular symptoms and optical coherence tomography (OCT) features of polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. Methods: Case report of two Caucasian patients with POEMS, one of whom also had multicentric Castleman disease. Results: Both patients presented with edema on both optic disks, bilateral macular edema was seen in case 1, and peripapillary choroidal neovascularization was seen on the right side in case 2. OCT confirmed papilledema involving all retinal layers, with additional bilateral peripapillary serous retinal detachment involving the macula in both cases, and peripapillary CNV in case 2. Changes in retinal nerve fiber layer thickness, total peripapillary retinal thickness, and macular detachment were followed with OCT over the course of the disease and after administration of systemic therapy. Conclusion: OCT examination of the optic nerve head and the macula has an important additional role in the diagnosis and follow-up of POEMS syndrome and Castleman disease.

Optic disc morphology in unilateral branch retinal vein occlusion using spectral domain optical coherence tomography

BackgroundThe aim of this study was to evaluate the association between optic nerve head (ONH) parameters and branch retinal vein occlusion (BRVO) using spectral domain optical coherence tomography (SD-OCT).MethodsBoth eyes of 40 patients with unilateral BRVO (mean age: 67.4 ± 11.4 years, male: female - 18:22) were enrolled in this study. Control group consisted of randomly selected single healthy eyes of 40 age and gender matched volunteers (mean age: 64.7 ± 15.4 years, male: female - 16:24). ONH parameters (including optic disc area, optic cup area, neuroretinal rim area, cup volume, rim volume, cup-disc area ratio, horizontal and vertical cup-disc ratio, average retinal nerve fiber layer) were measured by SD-OCT. Axial length (AL) of the eyes was measured by non-contact optical low coherence reflectometry. The ONH parameters of eyes with BRVO were compared with those of fellow eyes using mixed model, one-way between-groups analysis of covariance was conducted to compare the ONH parameters of affected and unaffected fellow eyes in BRVO patients with those of the control eyes keeping confounding factors, including AL, age and gender under control in the statistical analysis.ResultsNone of the investigated ONH parameters of affected BRVO eyes, unaffected fellow eyes and control eyes were statistically different after controlling for AL, age and gender.ConclusionOptic disc morphology might not be a potential anatomical predisposing factor for development of BRVO.

Choroidal thickness changes in non-treated eyes of patients with diabetes: swept-source optical coherence tomography study

AimsTo measure choroidal thickness (CT) in diabetic eyes and its correlation with metabolic status and the severity of diabetic retinopathy (DR).Materials and methodsProspective cross-sectional study using swept-source optical coherence tomography. CT maps of 96 treatment naïve eyes of 48 patients with diabetes were compared to 46 eyes of 23 healthy controls. CT changes and their relation to diabetes, age, gender, disease duration, hypertension (HT), hemoglobin A1c level, type and severity of DR were evaluated.ResultsA significantly thinner choroid was measured in patients with diabetes compared to controls (p < 0.009). In the diabetic group age, gender, disease duration and HT were significantly correlated with CT in univariable regression models (p < 0.05). In multivariable analysis, the duration of diabetes significantly negatively correlated with CT (p = 0.02). According to analysis of variance, there was a significant difference among means of CT in different stages of DR (p = 0.002), with thinner CT in cases with more advanced DR. In a multivariable predictive model, thinner CT was associated with an increased risk for the presence of DR (p = 0.02).ConclusionsDiabetes mellitus itself and the severity of DR affect CT significantly, even after adjusting for the effects of confounding systemic factors. Disease duration seems to be associated with a reduction of choroidal thickness. Decreased CT proved to be correlated with the severity of DR.

Stromal Cell-Derived Factor 1 Polymorphism in Retinal Vein Occlusion

Background Stromal cell-derived factor 1 (SDF1) has crucial role in the regulation of angiogenesis and ocular neovascularisation (NV). The purpose of this study was to evaluate the association between SDF1-3’G(801)A polymorphism and NV complications of retinal vein occlusion (RVO). Methods 130 patients with RVO (median age: 69.0, range 35–93 years; male/female– 58/72; 55 patients had central RVO, 75 patients had branch RVO) were enrolled in this study. In the RVO group, 40 (30.8%) patients were diagnosed with NV complications of RVO and 90 (69.2%) patients without NVs. The median follow up period was 40.3 months (range: 18–57 months). The SDF1-3’G(801)A polymorphism was detected by PCR-RFLP. Allelic prevalence was related to reference values obtained in the control group consisted of 125 randomly selected, age and gender matched, unrelated volunteers (median age: 68.0, range 36–95 years; male/female– 53/72). Statistical analysis of the allele and genotype differences between groups (RVO patients vs controls; RVO patients with NV vs RVO patients without NV) was determined by chi-squared test. P value of <0.05 was considered statistically significant. Results Hardy-Weinberg criteria was fulfilled in all groups. The SDF1-3’G(801)A allele and genotype frequencies of RVO patients were similar to controls (SDF1-3’A allele: 22.3% vs 20.8%; SDF1-3’(801)AA: 5.4% vs 4.8%, SDF1-3’(801)GG: 60.8% vs 63.2%). The frequency of SDF1-3’(801)AA and SDF1-3’(801)GA genotypes, as well as the SDF1-3’(801)A allele frequency were higher in RVO patients with NV versus in patients without NV complication (SDF1-3’(801)AA+AG genotypes: 57.5% vs 31.1%, p = 0.008; SDF1-3’(801)A allele: 35.0% vs 16.7%, p = 0.002) or versus controls (SDF1-3’(801)AA+AG genotypes 57.5% vs 36.8%, p = 0.021; SDF1-3’(801)A allele: 35.0% vs 20.8% p = 0.01). Carrying of SDF1-3’(801)A allele increased the risk of neovascularisation complications of RVO by 2.69 (OR, 95% CI = 1.47–4.93). Conclusion These findings suggest that carrying SDF1-3’(801)A allele plays a role in the development of neovascular complications in retinal vein occlusion.
