The socioeconomic epidemiology of inherited retinal diseases in Portugal.

Background: Inherited retinal diseases (IRDs) are a group of rare degenerative disorders of the retina that can lead to blindness from birth to late middle age. Knowing the target population and its resources is essential to better plan support measures. The aim of this study was to evaluate the socioeconomic characteristics of regions in Portugal where IRD patients reside to inform the planning of vision aid and rehabilitation intervention measures.

Design: Retrospective, single-center cohort study.

Participants: Patients with a clinical diagnosis of IRD were recruited at a referral center in Portugal.

Comparison of Color Fundus Photography and Multicolor Fundus Imaging for Detection of Lesions in Diabetic Retinopathy and Retinal Vein Occlusion.

Purpose: To evaluate the agreement between conventional fundus photography (CFP) and multicolor fundus imaging (MFI) for the detection of lesions of diabetic retinopathy (DR) and retinal vein occlusion (RVO).

Methods: Cross-sectional analysis of eyes with DR or RVO who underwent CFP and MFI. All images were independently analyzed by two observers (O1 and O2), and the evaluated lesions were classified as "present" or "absent".

Detection of subclinical microvascular changes in systemic lupus erythematous using optical coherence tomography angiography: A systematic review and meta-analysis.

Systemic lupus erythematosus (SLE) is a chronic, systemic, autoimmune connective tissue disease that affects several vascular territories. We sought to assess the role of optical coherence tomography angiography in detecting subclinical microvascular alterations in SLE patients. PubMed, Scopus, and Web of Science databases were systematically searched until January 21, 2023.

Retinal Changes After COVID-19 Infection and COVID-19 Vaccination.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease was first reported in 2019 and was initially associated with respiratory pathology. With the improvement of knowledge about this disease, it was noticed that, among other symptoms, some patients presented visual acuity changes associated with retinal vascular changes, mainly associated with thrombotic phenomena. Later, with the development of vaccines against SARS-CoV-2 disease, cases of visual acuity alterations secondary to thrombotic phenomena were also reported.

ACUTE MACULAR NEURORETINOPATHY FOLLOWING SARS-CoV-2 VACCINATION.

Purpose: To report a case of acute macular neuroretinopathy (AMN) following SARS-CoV-2 vaccination.

Methods: Case report.

Results: An otherwise healthy 28-year-old white woman presented to an ophthalmology department with complaints of black paracentral vision scotomata on both eyes that appeared 2 days after receiving the first dose of Vaxzevria vaccine.

Application of optical coherence tomography angiography for microvascular changes in patients treated with hydroxychloroquine: a systematic review and meta-analysis.

Background: Retinal toxicity with long-term hydroxychloroquine (HCQ) treatment is a major concern. This systematic review aims to assess the application of optical coherence tomography angiography (OCTA) to detect microvascular alterations in patients under HCQ.

Methods: PubMed, Scopus, Web of Science, and Cochrane Library databases were systematically searched until January 14, 2023.

Posterior Capsular Rupture during Cataract Surgery in Eyes Previously Treated with Intravitreal Injections.

Introduction: Intravitreal injections (IVIs) are currently the most common intraocular surgical procedure worldwide. Some studies have reported a higher risk of intraoperative complications, namely, posterior capsular rupture (PCR), during cataract surgery. The aim of this retrospective and observational study, conducted at Department of Ophthalmology, Centro Hospitalar Universitário do Porto, was to assess the risk of PCR during cataract surgery in eyes previously treated with IVIs with anti-vascular endothelial growth factor (anti-VEGF) and/or corticosteroids.

PARACENTRAL ACUTE MIDDLE MACULOPATHY AFTER COVID-19: MULTIMODAL EVALUATION.

Purpose: To report the case and multimodal imaging findings of a healthy young woman who developed paracentral acute middle maculopathy 9 weeks after COVID-19.

Methods: Case report. Ultra-widefield fundus photography, macular spectral domain optical coherence tomography, fluorescein angiography, and optical coherence tomography angiography were performed.

Choroidal neovascularization secondary to pathological myopia-macular Bruch membrane defects as prognostic factor to anti-VEGF treatment.

Purpose: To evaluate the prevalence and visual outcomes of macular Bruch membrane (BM) defects in patients treated with anti-vascular endothelial growth factors (VEGF) for choroidal neovascularization secondary to pathological myopia (mCNV).

Methods: Single-center retrospective observational case series of 68 eyes from 62 patients with mCNV treated with one anti-VEGF injection followed by a pro re nata (1 + PRN) regimen. A minimum follow-up of 6 months was defined.

Visian ICLV4c™ and Artiflex: Comparative Analysis with the HD Analyser and Integration with Subjective Performance and Anatomical Parameters.

Purpose: To analyze and compare the mid-term objective and subjective performance of two phakic intraocular lenses (PIOLs) - Visian ICL™ V4c and Artiflex and to correlate those results with anatomical parameters.

Patients And Methods: Observational retrospective study including thirty patients (15 for each PIOL) randomly selected from those who underwent bilateral implantation of one of the PIOLs (60 eyes were analysed). Uncorrected and corrected distance visual acuities (UDVA and CDVA), anterior chamber structural parameters, and corneal endothelial cells density and morphology were evaluated.

Optical Coherence Tomography Findings (SD-OCT and OCTA) in Early-Stage Type 3 Neovascularization.

A 76-year-old male presented with a small hyperreflective density in the outer nuclear layer with subtle retinal pigment epithelium (RPE) elevation and few intraretinal cysts on spectral-domain optical coherence tomography (SD-OCT). Optical coherence tomography angiography (OCTA) confirmed the presence of a tuft-shaped intraretinal neovascular lesion. SD-OCT performed 2 months before showed a smaller RPE elevation at the same location without intraretinal fluid.

Serum vitamin D and age-related macular degeneration: Systematic review and meta-analysis.

Vitamin D may be implicated in the pathophysiology of several ocular diseases, but its role in age-related macular degeneration (AMD) remains uncertain. We sought to review systematically the existing evidence to evaluate the association between serum 25-hydroxyvitamin D 25(OH)D levels and AMD. A four-database search (PubMed, ISI Web of Science, Cochrane, and Scopus) was performed from inception to May 2020 using the MeSH terms: ("Macular Degeneration" OR "Age-related macular degeneration" OR "Retinal degeneration" OR "Macula lutea") AND ("Vitamin D" OR "Ergocalciferols" OR "Cholecalciferol" OR "25-Hydroxyvitamin D").

Purtscher-like retinopathy.

Purtscher-like retinopathy is associated with retinal hemorrhages and ischaemia probably due to the complement-mediated leukoembolization. It is a rare and severe angiopathy found in conditions such as acute pancreatitis. Case.

Bilateral proliferative retinopathy as the initial presentation of chronic myeloid leukemia.

The authors report a rare case of a 48-year-old male with chronic myeloid leukemia (CML) who initially presented with a bilateral proliferative retinopathy. The patient complained of recent visual loss and floaters in both eyes (BE). Ophthalmologic evaluation revealed a best corrected visual acuity (BCVA) of 20/50 in the right eye and 20/200 in the left eye (LE).
