Article Synopsis
  • Central Serous Chorioretinopathy (CSC) is characterized by retinal detachments due to fluid leakage, often linked to stress, psychiatric issues, or corticosteroid use, prompting a study to investigate BALAD as a potential biomarker for CSC severity.
  • The research involved a global case-control study of patients with CSC, assessing clinical characteristics, risk factors, and OCT findings in those with and without Bacillary Layer Detachment (BALAD) to better understand its implications in diagnosis and treatment.
  • Results showed 37 patients with CSC and BALAD, revealing distinct clinical features on examination and OCT, compared to a control group without BALAD, suggesting significant differences in the manifestation of CSC.

Purpose: To analyse the longitudinal changes in imaging parameters in eyes with acute or chronic central serous chorioretinopathy (CSCR).

Methods: This was a multicentric, retrospective, longitudinal, observational study in patients with a diagnosis of CSCR and having at least 4 years of follow-up. Trend in choroidal thickness (CT), area of double layer sign (DLS), area of retinal pigment epithelium (RPE) alterations, and area of hyper-autofluorescence were analysed.

• Bacillary layer detachment (BALAD) may be associated with the systemic inflammatory reaction related to COVID-19 disease, and steroid use. • The causality spectrum of BALAD and vision losses can be followed by acute central serous chorioretinopathy presentation.

Introduction: Vision impairment and blindness have been significantly associated with high medical care expenditures, decrease in health utility, and loss or reduction of productivity. The objective of this study was to assess the humanistic and economic burden of blindness in a Brazilian sample from a societal perspective.

Methods: Cross-sectional, observational, and multicenter study enrolling individuals with blindness (defined as the best corrected visual acuity less than 6/60 in the better-seeing eye) caused by retinal disorders.

Purpose: To report the visual and anatomical outcomes in eyes with peripapillary choroidal neovascularisation (CNV) through 12 months.

Methods: This was a multicentre, retrospective, interventional case series which included treatment-naïve cases of peripapillary choroidal neovascular membrane (CNVM) with a minimum follow-up of 12 months. Multimodal imaging which comprised optical coherence tomography (OCT), fluorescein angiography and/or indocyanine green angiography was performed at baseline and follow-up visits.

Background And Objective: To evaluate the efficacy of combined bevacizumab-triamcinolone intravitreal injection in the treatment of diabetic macular edema (DME) compared to monotherapy.

Patients And Methods: At eight clinical sites, 111 patients with DME were randomly assigned to receive an intravitreal injection of bevacizumab (Avastin; Genentech, South San Francisco, CA), triamcinolone (Ophthalmos Pharmaceutical Industry, São Paulo-SP, Brazil), or their combination. The primary outcome was visual acuity (VA) at 6 months' follow-up.

Purpose: To study the outcomes of management of rhegmatogenous retinal detachment in eyes with chorioretinal colobomas.

Methods: A retrospective review of 119 patients (119 eyes) with chorioretinal colobomas who underwent surgical repair for rhegmatogenous retinal detachment was performed. Data were collected on the site of the retinal break, type of surgery, anatomical success, and complications.

Purpose: To report treatment outcomes of anti-vascular endothelial growth factor (VEGF) therapy in choroidal neovascularization (CNV) presenting after macular surgery.

Methods: Retrospective analysis of 7 eyes of 7 patients, who were diagnosed to have CNV after macular surgery and were treated with anti-vascular endothelial growth factor therapy. Collected data included demographic details; history of present illness; surgical procedure; and clinical examination including visual acuity at presentation and follow-up with imaging and management.

Methods: Retrospective analysis of 12 eyes of 12 patients, who were diagnosed to have CNV secondary to laser photocoagulation or PDT for central serous chorioretinopathy. Collected data included demographic details, history of presenting illness, clinical examination details including visual acuity at presentation, and follow-up with imaging and treatment details.

Background/aims: To compare the functional and anatomic outcomes of pars plana vitrectomy (PPV) with juxtapapillary laser photocoagulation (JLP) versus vitrectomy without JLP in optic disc pit maculopathy.

Methods: This was a multicentre, retrospective study of 46 consecutive patients with optic disc pit maculopathy presenting at tertiary eye centres between 1992 and 2012. Indications for surgery included distorted or decreased vision.

Purpose: This study aimed to evaluate the expression of the inflammatory cytokines TNF-α and IL-6 in the sclera and choroid of hypercholesterolemic rabbits.

Method: Twenty-one New Zealand male albino rabbits were divided into two groups: NG and HG. The NG group was fed a standard rabbit diet and the HG group was fed a cholesterol-enriched diet (1%).

Background: The purpose of this study was to determine the value of spectral domain optical coherence tomography (SD-OCT) in assessing patients with diffuse unilateral subacute neuroretinitis (DUSN).

Methods: This was an observational case series with clinical imaging correlation performed at the Retina and Vitreous Institute of Londrina and State University of Londrina, Paraná, Brazil. The series comprised ten consecutive patients with a confirmed diagnosis of DUSN, ie, seven patients with late-stage disease and three with early-stage disease, who were assessed by SD-OCT for mean macular, retinal nerve fiber layer, and choroidal thickness using enhanced depth imaging software.

Purpose: The aim of this study is to investigate the expression of vascular endothelial growth factor (VEGF) in the choroid and sclera using hypercholesterolemia experimental model.

Methods: New Zealand rabbits were divided into two groups: 8 rabbits (8 eyes), in the normal diet group (NG), were fed by a standard diet for 4 weeks; and 13 rabbits (13 eyes), in the hypercholesterolemic group (HG), were fed by a 1% cholesterol-enriched diet for 8 weeks. Total serum cholesterol, triglyceride, HDL cholesterol and fasting blood glucose exams were performed at the initiation of the experiment and at the euthanasia time.

Purpose: Demonstrate that the blockade of angiotensin II AT-1 receptors, through the systemic administration of olmesartan, can reduce the MCP-1 expression and the resulting macrophage accumulation in the choroid and sclera of hypercholesterolemic rabbits.

Methods: Thirty-two New Zealand rabbits were divided into 3 groups: group I (GI) was fed a standard rabbit diet; group II (GII) was fed a hypercholesterolemic diet; and group III (GIII) was fed a hypercholesterolemic diet plus olmesartan. Serum levels of total cholesterol, triglyceride, HDL cholesterol, and blood glucose were determined in fasting rabbits at the beginning of the experiment and on the day of euthanasia.

Article Synopsis
  • The study aimed to explore how treating Helicobacter pylori (H. pylori) infections affects vision and macular detachment in patients with chronic central serous chorioretinopathy (CSC).
  • Seventeen patients with CSC were tested for H. pylori; most were positive and treated, with improvements noted in their visual acuity and retinal health after treatment.
  • The results indicated a potential link between H. pylori infection and chronic CSC, suggesting that treating the infection could lead to better outcomes, although more rigorous research is needed to confirm these findings.

Congenital toxoplasmosis can cause miscarriage and neurological and/or eye damage to the fetus. Since Austria and France established the prenatal screening, the prevalence of toxoplasmosis has declined from 50% to 35% and 84% to 44%, respectively. Other countries, such as the United Kingdom, have educational practices to reduce the risk of infection in seronegative pregnant women.
