RETINAL BURNS IN PHOTIC RETINOPATHY: THREE CASE REPORTS.

Photic retinopathy (PR) is due to retinal phototoxicity, especially affecting the macula, resulting from exposure to sun, welding devices and lasers. It leads to oxidative damage to the retinal pigment epithelium (RPE) and the surrounding photoreceptors. Early recognition of this visual threatening condition, follow-up lesion evolution, and prevention of prolonged ocular exposure to lights is warranted.

Atypical Cogan's syndrome: A case report.

Cogan's syndrome is a rare autoimmune inflammatory disease, characterized by interstitial keratitis and audio-vestibular signs. The syndrome was first described in 1945 by David G. Cogan.

Diagnostic Accuracy and Relationship Between Optical Coherence Tomography Angiography Vessel Density and Structural/Functional Parameters in Healthy, Preperimetric, and Manifest Glaucoma Eyes.

Purpose: To evaluate circumpapillary vessel density (cpVD) in normal subjects, preperimetric glaucoma, and manifest glaucoma, assess the relationship between cpVD and both structural and functional parameters and compare the diagnostic accuracy of the structural and vascular measurements.

Methods: An analytical cross-sectional study of 153 eyes of 83 individuals divided into three groups: Normal subjects, preperimetric glaucoma, and manifest glaucoma. All individuals underwent standard automated perimetry, spectral-domain optical coherence tomography (SD-OCT), and OCT angiography (OCT-A) centered on the optic nerve.

[Forensic assessment of eye blasts in active military personal].

Background: Ocular blast injuries are defined as ocular damage caused by explosives. Within the military, they are considered work accidents resulting from military service, and they are therefore governed by the military disability pension system, which utilizes a specific scale.

Objectives: To study the clinical presentation and course of ocular blast injuries.

Role of Anterior Segment Optical Coherence Tomography in Monitoring Epidemic Keratoconjunctivitis.

Purpose: To describe, through anterior segment optical coherence tomography (AS-OCT) images, the different phases of epidemic keratoconjunctivitis (EKC) and show the impact of topical steroid on the course of this disease.

Methods: A prospective observational study included 38 eyes (28 patients) with a presumed EKC complicated by subepithelial infiltrates (SEIs) and treated with topical fluorometholone. Slit-lamp examinations and serial AS-OCT were performed on days 7, 14, 30, 90, 180, and 210.

Effects of Au/TiO metallic nanoparticles on Unio ravoisieri: assessment through an oxidative stress and toxicity biomarkers.

Several studies have been performed on the effects of nanoparticles on aquatic life. However, most of them investigated marine organisms, not freshwater organisms. This study investigated biomarker responses after exposure for 48 h and 7 days to newly made gold and titanium dioxide (Au/TiO) metallic nanoparticles (MNPs) (100 and 200 μg·L) using the freshwater bivalve mussel Unio ravoisieri.

Hyperbaric oxygen treatment of central retinal vein occlusion with cilioretinal artery occlusion secondary to hormonal treatment: Case report and review.

Introduction: This report describes a case of central retinal vein occlusion (CRVO) and cilioretinal artery occlusion (CLRAO) after hormonal treatment for induction of ovulation that was successfully treated with hyperbaric oxygen.

Case Report: A 48 year-old woman was admitted to our department for sudden blurred vision in her left eye. The patient had a history of 3-months hormonal treatment for induction of ovulation.

Corticosteroids Versus Cyclosporine for Subepithelial Infiltrates Secondary to Epidemic Keratoconjunctivitis: A Prospective Randomized Double-Blind Study.

Purpose: To compare efficiency and tolerance between topical 0.5% cyclosporine A (CSA) and fluorometholone (FML) for subepithelial infiltrates (SEI) complicating epidemic keratoconjunctivitis.

Methods: We conducted a prospective double-blind randomized study involving 72 eyes with SEI.

The effects of hyperbaric oxygen therapy on diabetic retinopathy: A preliminary study.

Purpose: The objective of this study was to prospectively assess the effect of hyperbaric oxygen therapy (HBOT) on diabetic retinopathy lesions and macular edema in patients undergoing the treatment for diabetic foot ulcers.

Methods: We compared two groups: a first group including 25 patients with non-proliferative diabetic retinopathy treated by HBOT for foot ulcers, and a second group (control group) composed of 25 patients with diabetic retinopathy who did not receive HBOT. The HBOT protocol performed for the patients in the first group was: 30 sessions of 90 minutes each at 2.

[Central serous chorioretinopathy: clinical-anatomic correlations].

Introduction: Central serous chorioretinopathy (CSCR) is a retinal disease characterized by a serous retinal detachment (SRD) responsible for a macular syndrome in young patients, often in the context of stress. In our study, we aimed to describe through multimodal analysis the clinical, angiographic and tomographic characteristics of CSCR while identifying prognostic factors and highlighting functional-anatomic correlations.

Methods: We conducted a retrospective, descriptive and analytic study over a period of 6 years on 35 eyes of 34 patients with CSCR.

Ozil® versus conventional ultrasound phacoemulsification: a randomized comparative study.

The purpose of this study is to compare and assess the performance and the postoperative outcomes of torsional mode and ultrasound (US) mode performed in the phacoemulsification of cataract with different nuclear densities. This is a randomized comparative clinical study. Two groups of 75 eyes (the first operated by Ozil(®) and the second by US) were comparable in age, gender, cataract density, corneal incision size, and intraocular lens type.

[Foveoschisis in highly myopic eyes: clinical and tomographic features].

Introduction: Foveoschisis is a rare condition in highly myopic eyes, characterized by intra-retinal cleavage associated with abnormalities of the vitreous cortex and occasionally cortical retraction. The natural history of foveoschisis is unpredictable. The functional prognosis is often favorable after surgical treatment.

[Angioid streaks complicated by choroidal neovascularization secondary to pseudoxanthoma elasticum: diagnosis and treatment. Case report].

Angioid streaks represent linear breaks in Bruch's membrane secondary to a change in the elastic layer. They are often associated with pseudoxanthoma elasticum. We report the case of a 36-year-old man with no prior history who was seen for a macular problem in the left eye, eventually involving the right eye after 3 months.
