Uveal melanoma is the most common primary intraocular malignancy. The aim of this retrospective study was to report results after ruthenium-106 (Ru-106) plaque brachytherapy for uveal in terms tumor control, visual acuity, radiation-related complications, recurrence, metastases, and patients' survival rate during 4 years' follow-up. A total 355 eyes from patients have been treated with Ru-106 between February 2011 March 2020. Five were lost follow-up, then 350 (mean age 58 ± 11 years)...

Purpose: The authors present a preliminary report to test the usefulness of new technique called power Doppler ultrasonography (PD) in study orbital vessels. Material and Methods: ophthalmic artery vein as well central retinal have been examined 10 patients with General Electric Logiq 5000 that allows examination both color (CD) PD. Results: PD does not alias, is relatively angle independent able better detect pathways these Conclusions: promising may be superior CD detecting ocular

Photorefractive keratectomy (PRK) was introduced in the late 1980s to correct myopia. The purpose of this study assess its long-term efficacy and safety, analyzing patients with at least 20-year follow-up.This retrospective observational carried out on 85 eyes 54 (33 females) that underwent PRK between 1991 1998 (mean age 32.62 ± 9.74, range 18-55 years). Both preoperatively postoperatively, a complete ophthalmological evaluation, including uncorrected corrected distance visual acuity,...

Abstract The corneal epithelium represents one of the main structures that undergo degenerative alterations due to antiglaucomatous therapy. Chronic glaucoma therapy containing benzalkonium chloride induces epithelial cellular changes and inflammatory infiltration in turn causes ocular surface resulting discomfort. Also, age‐related can involve tear film stability with reduction microvilli. objective this study is gain insights about glaucomatous patients divided according age, type duration...

To investigate the vessel density (VD) of radial peripapillary capillary (RPC) plexus in patients affected by preperimetric glaucoma (PPG), amnestic mild cognitive impairment (aMCI) and a healthy control group using optical coherence tomography angiography (OCTA) order to clarify pathogenetic mechanisms these neurodegenerative diseases.In this prospective study, we studied 54 eyes with PPG, aMCI controls. All subjects underwent structural spectral domain (SD)-OCT assess ganglion cell complex...

The purpose of this paper was to evaluate whether optical coherence tomography angiography (OCT-A) can be used quantify the vascular changes in radiation maculopathy, and tumor vasculature eyes treated with plaque radiotherapy for choroidal melanoma.In prospective study, we evaluated 39 Caucasian patients melanoma (39 eyes) ruthenium-106 radiotherapy. underwent complete ophthalmic examination, bulbar echography, OCT-A before 1 year after treatment.At baseline, mean best-corrected visual...

Abstract The aim of this study is to evaluate corneal epithelial thickness (CET), densitometry (CD) in 84 myopic eyes (57 patients) more than 22 years after photorefractive keratectomy, using anterior segment‐optical coherence tomography (AS‐OCT) and Scheimpflug imaging system. CET was significantly higher all operated unoperated central sector. A statistically significant increase CD layer sector shown groups with greater ablation depth respect eyes. While there no difference between the...

To determine if photorefractive keratectomy with a 193 nm excimer laser could cause human corneal endothelial changes, mainly in high dioptric treatments.18 patients underwent treatment ranging from 7 to 13 diopters at the apex (mean 10.3 +/- 1.4 SD) an estimated thinning 62 116 microns 90.7 12 SD). In these comparison between number and shape of cells has been performed before months after PRK.The mean cell density was 2818 337 mm2, surgery, 2894 301 mm2 months. The polymorphic index 79.0...

Purpose: This study evaluated the rate of change best corrected visual acuity (BCVA), central retinal sensitivity, and choroidal thickness in patients with macular edema after intravitreal bevacizumab. Methods: was a prospective, nonrandomized, interventional study. Thirty-four consecutive eyes (34 patients) were included Choroidal neovascularization present 21 cases, stage 1 angiomatous proliferation 6 branch vein occlusion 4 diabetic 3 cases. Evaluation BCVA (Early Treatment Diabetic...

This study describes the optical coherence tomography and angiography features of three eyes patients affected by contractile morning glory syndrome. Optical scans peripapillary retina revealed a dense microvascular network without any vascular difference between superficial plexus deep around optic nerve. These findings confirm that movement could be due to presence an autonomic cholinergic muscular mechanism in posterior part globe. In fact our cases, seemed induced massage eyeball. is...

ABSTRACT PURPOSE: To evaluate the effects of hardware and software improvements in photorefractive keratectomy (PRK) for treatment highly myopic eyes. METHODS: A retrospective study was carried out 554 patients (582 eyes) with myopia between -7.00 -17.00 D (mean -11.20 ± 3.60 D) who had undergone PRK using Aesculap Méditée laser. Group 1 a 5-mm-diameter single ablation zone; 2 zone surrounded by 2-mm tapered transitional 3 4, same as but laser upgraded smoke aspiration control system (Group...

Objectives To measure Optic Nerve Subarachnoid Space (ONSAS) in patients with primary open-angle glaucoma (POAG) and controls using A-scan ultrasound to evaluate the measurement of ONSAS relation age patient OCT parameters. Methods This retrospective study included 53 consecutive eyes 27 POAG 64 normal 32 controls. Both glaucomatous control groups were divided into 2 subgroups according age: <60 (glaucomatous group 1) 61–90 2). Results The was significantly lower all (3.54 ± 0.38) versus...

In this prospective study, we investigated the structural and vascular retinal changes at baseline after Ranibizumab injections last follow up to one year in patients affected by Radiation Maculopathy (RM) plaque brachytheraphy choroidal melanoma, using Spectral Domain Optical Coherence Tomography (SD-OCT) OCT Angiography (OCTA).
