Purpose: To demonstrate different topographic distributions of multiple-evanescent white dot syndrome (MEWDS) and secondary MEWDS disease and to describe possible associations.

Methods: Clinical evaluation and multimodal retinal imaging in 27 subjects with MEWDS (29 discrete episodes of MEWDS). Ophthalmic assessment included best-corrected visual acuity testing and multimodal retinal imaging with OCT, blue-light autofluorescence, fluorescein and indocyanine green angiography, fundus photography, and widefield pseudocolor and autofluorescence fundus imaging.

Diabetic Retinopathy (DR) is a leading cause of preventable visual impairment in the working age population. Despite the increasing prevalence of DR, there remain gaps in our understanding of its pathophysiology. This is a prospective case-control study comparing the genetic profiles of patients with no DR vs.

Introduction: Inherited retinal diseases (IRD) are a leading cause of visual impairment and blindness in the working age population. Mutations in over 300 genes have been found to be associated with IRDs and identifying the affected gene in patients by molecular genetic testing is the first step towards effective care and patient management. However, genetic diagnosis is currently slow, expensive and not widely accessible.

Lens extraction versus laser peripheral iridotomy for acute primary angle closure.

Cochrane Database Syst Rev

March 2023

Genentech Inc, South San Francisco, California, USA.

Background: Acute primary angle closure (APAC) is a potentially blinding condition. It is one of the few ophthalmic emergencies and carries high rates of visual morbidity in the absence of timely intervention. Laser peripheral iridotomy (LPI) has been the standard of care thus far.

Article Synopsis
  • The study evaluated the management of RPE65-IRD in Europe since the authorization of voretigene neparvovec (VN) in 2018, revealing that by July 2022, over 200 patients had been treated outside the USA, with 90% in Europe.
  • An electronic survey consisting of 48 questions was sent to numerous health care providers across Europe, receiving a 44% response rate, with 26 centers actively managing RPE65-IRD patients.
  • The results showed that while many centers have treated a number of patients, a significant percentage remained ineligible for treatment due to advanced or mild disease, and quality of life improvements from VN treatment were highly noted in follow-up outcomes.

Psychometric Validation of the ViSIO-PRO and ViSIO-ObsRO in Retinitis Pigmentosa and Leber Congenital Amaurosis.

Ophthalmol Ther

April 2023

Institut de la Vision, CHNO des Quinze-Vingts, National Rare Disease Center REFERET and INSERM-DGOS CIC 1423, Sorbonne Université, INSERM, CNRS, 75012, Paris, France.

Introduction: Retinitis Pigmentosa (RP) and Leber Congenital Amaurosis (LCA) are rare inherited retinal degenerative disorders. The Visual Symptom and Impact Outcomes patient-reported outcome (ViSIO-PRO) and observer-reported outcome (ViSIO-ObsRO) instruments were developed in this population to assess visual function symptoms and impacts on vision-dependent activities of daily living (ADL) and distal health-related quality of life (HRQoL). This study aimed to explore the psychometric properties of the ViSIO-PRO and ViSIO-ObsRO in RP/LCA.

Purpose: To develop a severity classification for macular telangiectasia type 2 (MacTel) disease using multimodal imaging.

Design: An algorithm was used on data from a prospective natural history study of MacTel for classification development.

Subjects: A total of 1733 participants enrolled in an international natural history study of MacTel.

Purpose: To evaluate the performance of different probabilistic classifiers to predict posterior capsule rupture (PCR) prior to cataract surgery.

Methods: Three probabilistic classifiers were constructed to estimate the probability of PCR: a Bayesian network (BN), logistic regression (LR) model, and multi-layer perceptron (MLP) network. The classifiers were trained on a sample of 2 853 376 surgeries reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO) between 2008 and 2018.

Inherited retinal diseases (IRD) are a clinically and genetically heterogenous group of diseases and a leading cause of blindness in the working-age population. Even though gene augmentation therapies have shown promising results, they are only feasible to treat a small number of autosomal recessive IRDs, because the size of the gene is limited by the vector used. DNA editing however could potentially correct errors regardless of the overall size of the gene and might also be used to correct dominant mutations.

Importance: X-linked retinitis pigmentosa (XLRP) is a severe cause of early-onset RP in male individuals, characterized by degeneration of photoreceptors, an extinguished electroretinogram, and vision loss.

Objective: To assess the duration of improvements in retinal sensitivity associated with a single, subretinal injection of cotoretigene toliparvovec (BIIB112/AAV8-RPGR) gene therapy after vitrectomy surgery in the dosed eye over 12 months in part 1 of the Clinical Trial of Retinal Gene Therapy for X-linked Retinitis Pigmentosa Using BIIB112 (XIRIUS) study, compared with untreated fellow eyes and eyes from the untreated subgroup from the Natural History of the Progression of X-Linked Retinitis Pigmentosa (XOLARIS) study.

Design, Setting, And Participants: This was a post hoc analysis of the XIRIUS and XOLARIS studies.

Purpose: The scotopic macular integrity assessment (S-MAIA) can perform scotopic assessment to detect localized changes to scotopic rod and cone function. This study is an exploratory investigation of the feasibility of using the S-MAIA in a rod-cone dystrophy population to identify the pattern of loss in scotopic photoreceptor function.

Methods: Twenty patients diagnosed with a rod-cone dystrophy underwent visual acuity testing, full-field stimulus threshold assessment, and multiple S-MAIA tests after dark adaptation periods of 20 minutes and 45 minutes performed separately.
