Diabetes has no additional impact on retinal ganglion cell loss in a mouse model of spontaneous glaucoma.

Purpose: There is no valid medical treatment for diabetic retinopathy mostly because its pathogenesis remains largely unknown. Early stages of diabetic retinopathy, just like glaucoma, are characterized by the loss of retinal ganglion cells. Whether the two diseases may share a similar pathogenic background is unknown.

New Findings in Early-Stage Keratoconus: Lamina Cribrosa Curvature, Retinal Nerve Fiber Layer Thickness, and Vascular Perfusion.

Purpose: Our aim was to investigate the involvement of posterior pole structures in eyes affected by keratoconus (KC). Optical coherence tomography (OCT) and OCT angiography (OCTA) were used to determine the status of lamina cribrosa (LC), peripapillary retinal nerve fiber layer (RNFL), macular and peripapillary microvasculature.

Design: Observational, cross-sectional, case-control analysis.

Quantitative Optical Coherence Tomography Angiography Detects Retinal Perfusion Changes in Carotid Artery Stenosis.

Background: Carotid artery stenosis (CAS) is a multifaceted disease characterized by possible ocular involvement. Treatment with carotid endarterectomy helps to restore cerebral perfusion, which may prevent ocular and cerebral complications. The main aim was to assess retinal and choroidal vascular perfusion changes before and after endarterectomy in patients affected by CAS.

Vitreomacular traction quantitative cutoffs for the assessment of resolution after ocriplasmin intravitreal treatment.

This study aimed to assess optical coherence tomography (OCT) parameters associated with vitreomacular traction (VMT) resolution after ocriplasmin intravitreal injection and also associated with the development of vitreomacular complications. Study designed was a retrospective case series. Structural OCT images were acquired at baseline and over the follow-up after treatment.

Extrafoveal Müller cells detection in vivo in the human retina: A pilot study based on optical coherence tomography.

Müller cells (MC) represent a key element for the metabolic and functional regulation of the vertebrate retina. The aim of the present study was to test the feasibility of a new method for the in-vivo detection and quantification of extrafoveal MC in human retina. We developed a new approach to isolate and analyse extrafoveal MC in vivo, starting from structural optical coherence tomography data.

Multimodal imaging of amelanotic choroidal melanoma.

Amelanotic choroidal melanoma (ACM) is an extremely rare malignant tumor affecting the uvea. Because of the complex structure characterizing this kind of lesions, its morphologic features are partially understood, especially if looking to its vascular network. In this paper, we described in details the multimodal imaging features of ACM.

The aim of this study was to perform quantitative optical coherence tomography angiography (OCTA) assessment of arteritic and non-arteritic anterior ischemic optic neuropathies (AION; NAION). The study was designed as an observational, cross-sectional case series. All patients underwent complete ophthalmologic evaluation including LogMAR best-corrected visual acuity (BCVA), structural optical coherence tomography (OCT) and OCTA images, and dye-based angiography.

Multimodal imaging in pediatric arterial macroaneurysm: A case report.

Our aim is to report a case of asymptomatic retinal arterial macroaneurysm in a 9-year-old female patient. She was referred to our Ophthalmology clinic for a routine ophthalmologic examination and, after the detection of a juxtafoveal saccular vascular enlargement in indirect ophthalmoscopy, underwent a multimodal imaging assessment. Optical coherence tomography-angiography and fluorescein angiography were important to determine the nature of the lesion, identified as a congenital retinal arterial macroaneurysm.

Bilateral Choroidal Osteoma Complicated by Bilateral Choroidal Neovascularization.

Choroidal osteoma is a rare, classically unilateral tumor. Less than half of the cases are complicated by the onset of choroidal neovascularization (CNV). The authors describe a case of bilateral choroidal osteoma in a 10-year-old female patient complicated by the onset of bilateral CNV.

Purpose: To investigate the retinal capillary perfusion density by means of optical coherence tomography angiography (OCT-A) in idiopathic epiretinal membrane (ERM) and macular pseudoholes (MPH).

Methods: This observational cross-sectional study examined consecutive patients affected by ERM and MPH presenting between June 2017 and December 2017, as well as the 30 eyes of 30 healthy subjects. All patients underwent swept-source OCT-A examination.

Higher Vascular Density of the Superficial Retinal Capillary Plexus in Degenerative Lamellar Macular Holes.

Background And Objective: Optical coherence tomography angiography (OCTA) comparison between vessel density in patients with degenerative-subtype lamellar macular hole (LMH) and healthy individuals. Unaffected fellow eyes were also included in the study.

Patients And Methods: This observational, cross-sectional study examined 32 eyes affected by unilateral degenerative-subtype LMH, as well as the 32 fellow eyes of the enrolled population.

The Use of OCT and OCT Angiography in Detecting an Atypical Case of Retinal Capillary Hemangioma.

Retinal capillary hemangioma (RCH) is a benign retinal tumor defined by a vascular proliferation localized in the peripheral retina, juxtapapillary retina, or the intraneural portion of the optic nerve. In most cases, diagnosis of RCH is performed by fundus evaluation and confirmed by fluorescein fundus angiography. Nevertheless, a small RCH localized on or adjacent to the optic nerve head could be difficult to detect by fundus examination.

HYPERREFLECTIVE FOVEAL SPOTS IN PATIENTS WITH VITREORETINAL ANOMALIES: A Qualitative and Quantitative Analysis.

Purpose: To describe structural optical coherence tomography (OCT) and OCT angiography features in patients who have developed hyperreflective foveal spots with or without vitreomacular interface abnormalities or with vitreous adhesion alone.

Methods: The study design was observational and cross sectional. The presence of defined epiretinal membrane was considered an exclusion criterion.

Choroidal Neovascularization in Torpedo Maculopathy Assessed on Optical Coherence Tomography Angiography.

Torpedo maculopathy is characterized by a congenital, unilateral, and torpedo-shaped chorioretinal lesion with unclear pathogenesis and evolution. Although the optical coherence tomography angiography (OCTA) characteristics have already been defined in literature, the authors describe for the first time the presence of choroidal neovascularization (CNV) on the temporal edge of this lesion in a 36-year-old woman with a history of altered visual field in her left eye. The authors' investigation supports the hypothesis of an aberrant choroidal circulation underlying the pathogenesis of this condition, and proves the advantage conferred by OCTA in CNV detection over the other angiographic techniques.

En Face Optical Coherence Tomography Angiography of Primary Vitreoretinal Lymphoma.

The authors report a case of a female patient affected by primary vitreoretinal lymphoma (PVRL) showing retinal involvement. In particular, multiple subretinal hyperreflective infiltrates were found on optical coherence tomography (OCT). These alterations appeared hyperautofluorescent on fundus autofluorescence images.

Resolution of cystoid macular edema following arginine-restricted diet and vitamin B6 supplementation in a case of gyrate atrophy.

We report the outcome of 3 years of arginine-restricted diet and vitamin B6 supplementation in a boy who presented with gyrate atrophy of the choroid and retina and bilateral cystoid macular edema. The diagnosis of gyrate atrophy was made on the basis of clinical findings and increased plasma ornithine levels. Molecular genetic testing revealed a disease-causing homozygous mutation in the ornithine aminotransferase (OAT) gene.
