Fungal keratitis (FK) is a serious pathogenic disease usually associated with serious ocular complications. The current mainstay of treatment for FK is topical eye drops; however, poor corneal penetration, low bioavailability of the drug and the need to administer high and frequent doses due to the presence of an effective clearance mechanism in the eye result in poor patient compliance. Nanocarriers can extend the duration of drug action through sustained and controlled release of the drug, protect the drug from ocular enzymes and help overcome ocular barriers...

INTRODUCTION: Idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome is a rare clinical entity affecting young healthy individuals. Treatment primarily involves pan retinal photocoagulation (PRP) to capillary non perfusion areas. Intravitreal anti-VEGF or steroids are given in the presence of macula edema. Oral steroids do not alter the course of the disease. Arterial occlusions have been reported in IRVAN. METHODS: Retrospective case review...

PURPOSE: To study peripheral capillary non-perfusion (PCN-P) in branch retinal vein occlusion (BRVO) by means of ultra wide-field fluorescein angiography (UWFFA), and to correlate its extent and severity with optical coherence tomography (OCT) and OCT-angiography (OCTA) parameters and best corrected visual acuity (BCVA). METHODS: Prospective case series with 2 years of planned follow-up. We recruited patients from June 2019 to December 2019. Ophthalmologic examination included BCVA, UWFFA, OCT and OCTA...

INTRODUCTION: Intravitreal dexamethasone (DEX) implant is indicated for the treatment of macular oedema due to diabetic retinopathy, retinal vein occlusion and uveitis. The most common complications are cataract and elevated intraocular pressure (IOP). Accidental injection of DEX implant into the lens is a rare complication and only few papers presented it. CASE PRESENTATION: A 40-year-old man was treated with DEX implant for diabetic macular oedema in both eyes...

INTRODUCTION: Bilateral acute iris transillumination (BAIT) is a relatively new syndrome whose etiopathogenesis is still not fully understood. It is characterized by acute bilateral onset of intense pigment dispersion in the anterior chamber, iris depigmentation with severe transillumination defects, accentuated pigment deposition in the angle, and elevated intraocular pressure (IOP). In literature, the first case was of bilateral acute iris depigmentation (BADI) reported in 2004 in a 77-year-old woman...

PURPOSE: The aim of this study is to analyze the distribution of visual field (VF) mean defect (MD) in six subgroups of glaucoma patients at baseline and follow-up. METHODS: We assessed glaucoma patients treated in a Spanish tertiary care setting with a follow-up of at least 10 months. We have included 1036 visual fields and the following glaucoma subtypes: open-Angle Glaucoma (OAG); Angle-Closure Glaucoma (ACG); Congenital Glaucoma (CG); Ocular hypertension (OHT); Pseudoexfoliative Glaucoma (PSXG); Pigmentary Glaucoma (PG)...

BACKGROUND: Oculofaciocardiodental (OFCD) syndrome is a rare genetic disorder affecting ocular, facial, dental, and cardiac systems, being an X-linked condition caused by pathogenic variants in the BCL-6 corepressor gene ( BCOR ). We report a case series of three female patients with OFCD syndrome with severe glaucoma. RESULTS: Three female patients with OFCD syndrome with different variants involving BCOR gene, in heterozygosity: a seven-years-old girl with an insertion (c...

PURPOSE: To determine the total alpha-synuclein (αSyn) reflex tears and its association with retinal layers thickness in Parkinson's disease (PD).

The gut microbiome is a complex ecosystem in the gastrointestinal tract composed of trillions of bacteria, viruses, fungi, and protozoa. Disruption of this delicate ecosystem, formally called "dysbiosis", has been linked to a variety of metabolic and inflammatory pathologies. Several studies have focused on abnormal microbiome composition and correlated these findings with the development of type 2 diabetes mellitus (T2DM) and diabetic retinopathy (DR). However, given the complexity of this ecosystem, the current studies are narrow in design and present variable findings...
