Purpose: The purpose of this study was to determine the association between corneal images provided by in vivo confocal microscopy (IVCM) with clinical parameters and conjunctival expression of HLA-DR antigen in patients with dry eye disease (DED).
Methods: Two hundred fourteen eyes of 214 patients with DED were analyzed, consisting of 2 groups of patients - 63 with autoimmune dry eye disease (AIDED) and 151 with non-autoimmune dry eye disease (NAIDED). Patients underwent a full clinical examination, including symptom screening, using the Ocular Surface Disease Index (OSDI) questionnaire, and objective analysis of DED signs by Schirmer's testing, tear break-up time (TBUT), Oxford's test, and IVCM corneal imaging.
Background: Intraocular dexamethasone implant (DEXi) is an efficient treatment for diabetic macular edema (DME). However, it may be unavailable or contraindicated. Triamcinolone acetonide is another corticosteroid that has proved to be safe and effective in treating macular edema complicating various diseases including diabetes.

Aim: While diabetic retinopathy is the most specific complication of chronic hyperglycaemia, numerous other ocular conditions also can involve the eyes of people with diabetes. Cataract, glaucoma, age-related macular degeneration, retinal vascular occlusion, and acute ischaemic optic neuropathy combine to impair vision in people with diabetes, especially when they are old. This report provides a critical analysis and an overview of the current knowledge of the main ocular disorders (excluding diabetic retinopathy) and their association in patients with diabetes.

The aim of this survey was to explore the lived experience, knowledge, fears and expectations about disease, and treatment in patients with diabetes and macular edema treated with intravitreal injections (IVTI) and to characterize patient profiles.
Methods: Cross-sectional survey including a preliminary qualitative phase (20 patients with DME, treated or treatment-naive, 5 female and 15 male, age 36-74 years) followed by a quantitative survey (116 patients treated with IVTI for DME).
Purpose: The aim of this study was to define the role of dystrophin Dp71 in corneal angiogenesis.
Methods: Inflammation-induced corneal neovascularization experiments were performed in -null mice and C57BL/6J wild-type mice.
Results: The corneal neovascular area covered by neovascularization was larger in the injured corneas of the -null mice compared to the corneas of the wild-type mice: 40.
Aims: Recent trials provide conflicting results on the association between glucagon-like peptide 1 receptor agonists (GLP-1RA) and diabetic retinopathy (DR). The aim of the AngioSafe type 2 diabetes (T2D) study was to determine the role of GLP-1RA in angiogenesis using clinical and preclinical models.
Methods: We performed two studies in humans.
Purpose: To assess change in retinal nonperfusion (NP) after anti-vascular endothelial growth factor (VEGF) therapy for diabetic macular edema (DME) using 2 different imaging modalities: swept-source widefield (SS-WF) OCT angiography (OCTA) and ultra-widefield (UWF) fluorescein angiography (FA).
Design: Observational case series.
Participants: Ten eyes of 9 patients with severe nonproliferative diabetic retinopathy (NPDR) or proliferative DR (PDR) initiating 3 monthly anti-VEGF intravitreal injections for DME.
Aims: During diabetic macular oedema (DME), a spectrum of capillary abnormalities is commonly observed, ranging from microaneurysms to large microvascular abnormalities. Clinical evidence suggests that targeted photocoagulation of large microvascular abnormalities may be beneficial, but their detection is not done in a routine fashion. It was reported that they are better identified by indocyanine green angiography (ICGA) than by fluorescein angiography.

Methods: Retrospective analysis of 17 eyes of 17 Type 1 diabetes (T1D) patients with severe non-proliferative or proliferative DR and no current or past macular edema. Seventeen age- and sex-matched healthy subjects were included as controls.
Treatment of persistent ocular discomfort in patients with Cogan's epithelial basement membrane dystrophy (EBMD) is a challenge for ophthalmologists. This study aimed to determine the efficacy of a topical heparan sulfate mimetic polymer (HSMP) in reducing ocular discomfort in EBMD patients. This retrospective, noninterventional study included 22 consecutive patients in 3 tertiary ophthalmological units with spontaneous, recurrent, acute ocular pain, resistant to various topical lubricants.
View Article and Find Full Text PDFPurpose: To analyze the evolution of macular vessel density (VD) over 1 year, during early worsening of diabetic retinopathy, in patients with uncontrolled Type 1 diabetes (T1D).
Methods: Retrospective study of 12 eyes of 9 patients with T1D with early worsening of diabetic retinopathy imaged with optical coherence tomography angiography. The following data were collected at the time of pan retinal photocoagulation initiation and after 6 and 12 months: vessel density within three retinal plexuses-superficial vascular plexus, intermediate capillary plexus, and deep capillary plexus; foveal avascular zone area, acircularity index, and flow density (FD)-300; central macular thickness; and HbA1c levels.
Purpose: To compare the changes in retinal perfusion on ultra-wide-field fluorescein angiography with the changes in diabetic retinopathy lesions observed on ultra-wide-field fundus color photographs after 3 monthly anti-vascular endothelial growth factor injections.
Methods: Retrospective interventional cohort study analyzing the files of 14 patients with DR (18 eyes). UWF color photos and FA were analyzed at baseline (M0) and 1 month after the third anti-VEGF injection (M3).
Importance: Capillary dropout is a hallmark of diabetic retinopathy, but its role in visual loss remains unclear.
Objective: To examine how macular vessel density is correlated with visual acuity (VA) in patients younger than 40 years who have type 1 diabetes without macular edema but who have diabetic retinopathy requiring panretinal photocoagulation.
Design, Settings, And Participants: Retrospective cohort study of VA and optical coherence tomography angiography data collected from consecutive patients during a single visit to Lariboisière Hospital, a tertiary referral center in Paris, France.
Purpose: To report the feasibility and information provided by intraoperative optical coherence tomography (iOCT) during vitreomacular surgery in highly myopic eyes.
Methods: Retrospective observational case series on consecutive highly myopic eyes that underwent vitreomacular surgery with iOCT for epiretinal membrane (ERM), macular hole, and myopic foveoschisis. The main outcome was the qualitative and quantitative assessment of retinal changes: detection of persistent epiretinal structures, new openings, central macular thickness, and macular hole diameters after each step of the surgical procedure.

Background And Objective: To analyze cone mosaic metrics on adaptive optics (AO) images as a function of retinal eccentricity in two different age groups using a commercial flood illumination AO device.
Patients And Methods: Fifty-three eyes of 28 healthy subjects divided into two age groups were imaged using an AO flood-illumination camera (rtx1; Imagine Eyes, Orsay, France). A 16° × 4° field was obtained horizontally.
Purpose: To study the relationship between the location of cystoid spaces and retinal capillary nonperfusion areas in diabetic cystoid macular edema (DCME).
Methods: In this retrospective study, 24 eyes of 21 patients with chronic DCME were followed using optical coherence tomography angiography. The capillary density of the superficial capillary plexus and deep capillary plexus was measured using AngioAnalytics software in all DCME eyes and in 20 healthy controls.
Background: To evaluate quantitative and qualitative changes in sub-basal corneal nerves (SBN) via in vivo confocal microscopy in patients with Sjögren syndrome dry eye (SSDE) treated with topical cyclosporine A (CsA).
Design: Prospective, observational, non-randomized study.
Participants: Thirty eyes of 30 patients with SSDE refractory to conventional treatment treated with CsA 0.
Purpose: To evaluate the efficacy and safety of sustained-delivery fluocinolone acetonide (FAc) intravitreal implant for diabetic macular edema (DME).
Patients And Methods: Prospective study in patients with DME insufficiently responsive to laser and anti-vascular endothelial growth factor (anti-VEGF). Patients with history of rise of intraocular pressure after intravitreal corticosteroids were excluded.
Importance: Small fiber neuropathy (SFN) is an important feature of transthyretin familial amyloid polyneuropathy (TTR-FAP). A practical and objective method for the clinical evaluation of SFN is needed to improve the management of this disease. In vivo confocal microscopy (IVCM) of the corneal nerves, a rapid noninvasive technique, may be used as a surrogate marker of SFN.
