Extensive macular atrophy with pseudodrusen-like appearance (EMAP) clinical characteristics, diagnostic criteria, and insights from allied inherited retinal diseases and age-related macular degeneration.

Extensive macular atrophy with pseudodrusen-like appearance (EMAP) was first described in France in 2009 as a symmetric and rapidly progressive form of macular atrophy primarily affecting middle-aged individuals. Despite the recent identification of a significant number of cases in Italy and worldwide, EMAP remains an underrecognized condition. The clinical triad typical of EMAP consists of vertically oriented macular atrophy with multilobular borders, pseudodrusen-like deposits across the posterior pole and mid-periphery, and peripheral pavingstone degeneration.

Imaging-Guided Classification of Neovascularization in Neovascular Age-Related Macular Degeneration: Progress to Date.

To review the evolution of terminology describing the classification of lesions in neovascular age-related macular degeneration (nAMD) based on retinal imaging technologies. A review of the current and historical literature on imaging-guided classification of neovascularization in nAMD was performed. Imaging-guided classification of neovascularization in nAMD facilitates understanding of the pathological mechanisms and disease progression.

Informing Endpoints for Clinical Trials of Geographic Atrophy.

Geographic atrophy (GA), the non-neovascular advanced form of age-related macular degeneration, remains an important disease area in which treatment needs are currently unmet. Recent clinical trials using drugs that target the complement pathway have shown modest yet consistent reductions in GA expansion but without commensurate changes in measures of visual function. In this review, we summarize information from the wide range of studies describing the characteristics of GA morphology and enumerate the factors influencing the growth rates of lesions and the directionality of expansion.

Ten-Year Follow-Up of Fellow Eyes in Patients with Unilateral Naïve Exudative AMD.

Purpose: To determine the 10-year morphological outcomes and identify potential risk factors for exudative AMD in the fellow eyes (FE) in patients with naïve exudative AMD.

Methods: 140 eyes from 96 patients were included in this observational, cross-sectional study: 40 ACTIVE uveitis, 40 INACTIVE uveitis and 60 CONTROLS. All eyes underwent intraocular inflammation clinical grading (anterior chamber (AC) cells counting and vitreous haze evaluation) and AV imaging with SS-ASOCT.

Voretigene neparvovec for inherited retinal dystrophy due to RPE65 mutations: a scoping review of eligibility and treatment challenges from clinical trials to real practice.

Biallelic mutations in the RPE65 gene affect nearly 8% of Leber Congenital Amaurosis and 2% of Retinitis Pigmentosa cases. Voretigene neparvovec (VN) is the first gene therapy approach approved for their treatment. To date, real life experience has demonstrated functional improvements following VN treatment, which are consistent with the clinical trials outcomes.

Resolution of epiretinal membrane after anti-VEGF and photodynamic therapy of retinal hemangioblastoma.

Purpose: To describe the clinical and multimodal imaging features in a case of resolution of pre-macular fibrosis after photodynamic therapy (PDT) of retinal hemangioblastoma (RH) not related to von-Hippel-Lindau (VHL).

Observations: A 25-year-old man presenting with blurred vision and central metamorphopsia in his left eye (LE) due to macular epiretinal membrane secondary to a peripheral RH. The patient had a comprehensive ophthalmic examination, including best corrected visual acuity (BCVA), wide-field fundus photography and autofluorescence (FAF), wide-field optical coherence tomography (OCT) and OCT angiography (OCTA), fluorescein angiography (FA) and indocyanine green angiography (ICGA) and ocular ultrasound.

Immunomodulatory Treatment Versus Systemic Steroids in Inflammatory Choroidal Neovascularization Secondary to Idiopathic Multifocal Choroiditis.

Purpose: To evaluate the influence of immunomodulatory therapy (IMT) on visual and treatment outcomes of inflammatory choroidal neovascularization (iCNV) in patients affected by multifocal choroiditis (MFC), and to compare them to patients treated with steroids as needed.

Design: Multicenter retrospective matched cohort study.

Methods: Patients affected by MFC with iCNV were divided into a IMT group and a "steroids as needed" group and matched according to the time between diagnosis and beginning of systemic treatment.

Case report: Surgical management of vitreous obstruction following PreserFlo ® MicroShunt implantation.

Purpose: To describe a clinical case of lumen obstruction a few days after implantation of the PreserFlo® Microshunt which has been resolved by anterior vitrectomy.

Observation: A 76-year-old patient with advanced and progressing primary open-angle glaucoma (POAG) presented ten days after PreserFlo® Microshunt implantation in his left eye with an intraocular pressure (IOP) of 24 mmHg because of vitreous obstruction. Anterior vitrectomy with 25 Gauge vitrector was performed to remove the vitreous using a bimanual technique with two corneal accesses.

Towards a Long-Read Sequencing Approach for the Molecular Diagnosis of RPGR Genetic Variants.

Sequencing of the low-complexity ORF15 exon of RPGR, a gene correlated with retinitis pigmentosa and cone dystrophy, is difficult to achieve with NGS and Sanger sequencing. False results could lead to the inaccurate annotation of genetic variants in dbSNP and ClinVar databases, tools on which HGMD and Ensembl rely, finally resulting in incorrect genetic variants interpretation. This paper aims to propose PacBio sequencing as a feasible method to correctly detect genetic variants in low-complexity regions, such as the ORF15 exon of RPGR, and interpret their pathogenicity by structural studies.
