angioid streaks

Pseudoxanthoma elasticum, or Gronblad-Strandberg syndrome, is an inherited disorder that involves multiple organ systems. The characteristic degeneration and calcification of the elastic fibers caused by this disease were first observed by Ferdinand Jean Darrier in 1896. We report a case of a 27-year-old female who was diagnosed with pseudoxanthoma elasticum based on a skin biopsy prior to her presentation to our ophthalmology outpatient clinic. The past ocular history of the patient was unremarkable for any previous eye complaint or surgery...

BACKGROUND/PURPOSE: To describe the association between autosomal dominant Best disease and peripapillary angioid streak-like changes. METHODS: Case report of two siblings. RESULTS: A 76-year-old Caucasian male was referred for evaluation of bilateral macular changes and worsening visual distortion over the preceding 2 years. Best corrected visual acuity (BCVA) measured 20/30 in the right eye and 20/80 in the left eye. Funduscopic examination revealed multifocal yellow lesions in the posterior pole that were hyper-autofluorescent on short-wavelength excitation and corresponded with subretinal hyperreflective material on optical coherence tomography...

OBJECTIVES: To inspect the inter-reader agreement of different diagnostic modalities in identifying choroidal neovascularization (CNV) activity secondary to angioid streaks (AS) and to analyze the prevalence of subretinal hyper-reflective material (SHRM) in active CNV. METHODS: Retrospective study of patients with AS with active CNV; optical coherence tomography (OCT), OCT angiography (OCTA), fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) from each patient were collected...

BACKGROUND AND AIMS: Pseudoxanthoma elasticum (PXE) is caused by variants in the ABCC6 gene. It results in calcification in the skin, peripheral arteries and the eyes, but has considerable phenotypic variability. We investigated the association between the ABCC6 genotype and calcification and clinical phenotypes in these different organs. METHODS: ABCC6 sequencing was performed in 289 PXE patients. Genotypes were grouped as two truncating, mixed, or two non-truncating variants...

The aim of this study was to report unusual progression of type 2 macular neovascularization (MNV) associated with age-related macular degeneration (AMD), high myopia or angioid streaks. Retrospective multicentric observational case series data were used. Eyes that progressed from type 2 MNV secondary to AMD, high myopia or angioid streaks to fibrovascular pigment epithelial detachment (PED) were included. A total of 29 treatment-naive eyes from 29 patients with type 2 MNV secondary to AMD ( n = 14), high myopia ( n = 10) or angioid streaks ( n = 5) that progressed to a fibrovascular PED on Spectral Domain-Optical Coherence Tomography were used...

SIGNIFICANCE: Alagille syndrome is rare genetic disease, which affects liver and heart function. Cases are frequently diagnosed late, and a complete ocular examination aids in the diagnosis. Although ophthalmic manifestations are usually benign, occasionally, sight-threatening complications occur. PURPOSE: The case presented herein highlights a rare condition, which usually can be diagnosed by the ophthalmological findings. However, in this particular case report, the complication of angioid streaks and choroidal neovascularization is reported for the first time in Alagille syndrome...

OBJECTIVE: We report the association of polypoid choroidal vasculopathy (PVC) with angioid streaks (AS) secondary to pseudoxanthoma elasticum (PXE) treated by intravitreal injection of bevacizumab. CASE REPORT: A 50-year-old patient, followed in dermatology for a PXE, who consulted for a consulted for a decreased vision in his right eye (RE) for a month. On examination, best corrected visual acuity (BCVA) was at 1/20 P14 in the RE and at 8/10 P2 in the left eye (LE)...

A 65-year-old female patient was referred to our hospital for evaluation for cataract surgery. Her past medical history included corrective jaw surgeries for facial deformities that developed during infancy and persisted through early adulthood. A complete ophthalmological examination revealed bilateral angioid streaks, drusen in both optic disc areas, and a subretinal neovascular membrane in the left macula. Genetic analysis revealed a mutation in the SH3BP2 gene compatible with the diagnosis of cherubism...

PURPOSE: To study the appearance of angioid streaks (AS) in swept source optical coherence tomography angiography. METHODS: Retrospective observational study of 16 patients (31 eyes) with various stages of AS. All included patients underwent complete ophthalmologic examinations including best-corrected visual acuity (BCVA), slit-lamp examination, indirect ophthalmoscopy and fundus photography. Swept source optical coherence tomography (SS-OCT), OCT angiography (OCT-A) and fluorescein angiography were also performed...

OBJECTIVE: To describe a clinical picture resembling classic multiple evanescent white dot syndrome (MEWDS) potentially triggered by previous or concurrent, apparently unrelated, ocular events and to provide a literature review of similar presentations. DESIGN: Retrospective chart series and narrative review. PARTICIPANTS: Consecutive sample of patients diagnosed with MEWDS at the Feinberg School of Medicine at Northwestern University (Chicago, Illinois) and IRCCS San Raffaele Scientific Institute (Milan, Italy) between July 2019 and June 2020...

PURPOSE: To evaluate the risk of active choroidal neovascularization (CNV) in presence of deep irregular vascular network (IVN) in eyes with angioid streaks (AS). METHODS: Observational case series including three treatment-naive eyes with angioid streaks and IVN, without CNV. Patients were followed-up during 18 months with multimodal imaging including structural optical coherence tomography (OCT) and OCT Angiography (OCT-A) to detect possible neovascular complication...

PURPOSE: To describe the retinal findings of patients affected by pseudoxanthoma elasticum (PXE) using a multimodal imaging approach including flood-illumination adaptive optics ophthalmoscopy (AO). DESIGN: Retrospective case series. MATERIALS AND METHODS: Patients affected by PXE were retrospectively studied. Clinical data, color, infrared and autofluorescence fundus imaging, optical coherence tomographic scans, and AO examinations were collected...

This case series illustrates clinical features and treatment outcomes of angioid streak associated CNV (AS-CNV) in 3 consecutive patients. Mean age of patients was 43.2 years with one female patient. Bilateral CNV was present in one patient. Comet-tail lesions were present in all cases. No underlying systemic association was found in any of the patients. All patients were treated with 3 loading doses of anti-VEGF injections (ranibizumab in two and aflibercept was used in one case). Subretinal fluid resolved in all cases with no recurrence of CNV activity at mean follow-up of 10...

PURPOSE: Pseudoxanthoma elasticum (PXE) is a recessive disorder involving skin, eyes and arteries, mainly caused by ABCC6 pathogenic variants. However, almost one fifth of patients remain genetically unsolved despite extensive genetic screening of ABCC6, as illustrated in a large French PXE series of 220 cases. We searched for new PXE gene(s) to solve the ABCC6-negative patients. METHODS: First, family-based exome sequencing was performed, in one ABCC6-negative PXE patient with additional neurological features, and her relatives...

PURPOSE: To characterize morphological changes in the retina and to report the frequency and natural history of non-exudative macular neovascularization (MNV) in a cohort of pseudoxanthoma elasticum (PXE). METHODS: A single-center, retrospective study was complemented by a cross-sectional examination. Consecutive patients with a definitive genetic and/or clinical diagnosis of PXE, visiting our department between January 2019 and December 2019, and with a minimum follow-up of 6 months were recruited...

Pseudoxanthoma elasticum (PXE) is a multisystem disorder characterized by ectopic mineralization of connective tissues with primary manifestations in the skin, eyes, and cardiovascular system. The classic forms of PXE are caused by mutations in the ABCC6 gene encoding the ABCC6 protein expressed primarily in the liver. Cutis laxa (CL) manifests with loose and sagging skin with loss of recoil. In 2009 we investigated a 19-year-old patient with overlapping cutaneous features of PXE and CL, together with alpha thalassemia...

Angioid streaks (AS) are irregular crack-like dehiscences in Bruch's membrane that are often associated with atrophic degeneration of the overlying retinal pigment epithelium. We herein report multimodal imaging of AS. Multicolor imaging highlighted AS in dark orange color. AS were better visualized in infrared reflectance as compared to green reflectance and blue reflectance. Peau d'orange appearance was seen as alternating dark and bright patches on color fundus photography with corresponding hyporeflective and hyperreflective patches on infrared reflectance...

The article presents a clinical case of using anti-VEGF therapy in the treatment of retinal neovascularization consequent to angioid streaks (AS). Angioid streaks are linear breaks or divergences in an abnormally brittle or calcified Bruch's membrane. The development of choroidal neovascularization (CNV) due to AS is one of the most serious complications of the disease and the main cause of visual impairment, especially in active middle-aged patients. Currently, determination of the morphology and activity of CNV is done using multimodal macular imaging methods such as optical coherence tomography of the retina (OCT), optical coherence tomography angiography (OCT-A), fluorescin angiography (FA), indocyanine green angiography (ICGA) and autofluorescence...

PURPOSE: To investigate whether the extent of Bruch's membrane calcification is associated with choroidal neovascularization (CNV) and macular atrophy in patients with pseudoxanthoma elasticum (PXE) by using the extent of angioid streaks as a surrogate marker for the degree of Bruch's membrane calcification. DESIGN: Retrospective cross-sectional study. METHODS: We investigated 301 patients with PXE (median age, 52 years; range, 9-79 years) in a tertiary referral center...
