Prevalence and risk factors of diabetic retinopathy in adult and elderly subjects. The Casteldaccia Eye Study
2003
PURPOSE: To investigate the prevalence and risk factors of diabetic retinopathy in subjects aged 40 years or older living in Casteldaccia, Sicily. METHODS: A population-based survey was performed on 1,588 subjects randomly enrolled among people aged 40 years or older. A total of 1,068 persons could be examined and in 1,019 the fundus of the eye was adequately observed (64.2% of the enrolled population). Diabetic retinopathy was diagnosed by ophthalmoscopy and fundus photographs; fluorescein angiography was performed in 91% of retinopathic subjects. In addition, a case-control study was carried out in order to demonstrate the association of diabetic retinopathy with a number of variables. RE…
Intravitreal anti-vascular endothelial growth factors, panretinal photocoagulation and combined treatment for proliferative diabetic retinopathy: a s…
2020
Purpose: to conduct a systematic review with network meta‐analysis (NMA) of randomized clinical trials (RCTs) comparing panretinal photocoagulation (PRP) versus anti‐vascular endothelial growth factor (VEGF) treatment alone or in combination with PRP, for proliferative diabetic retinopathy (PDR).Methods: PubMed, Medline and Embase databases were searched for RCTs comparing PRP versus intravitreal anti‐VEGF therapy and/or combined PRP and intravitreal anti‐VEGF for PDR. The primary outcome measures were the mean best corrected visual acuity (BCVA) change and the regression of neovascularization. Mean change of central macular thickness (CMT), the subgroup analyses of patients without diabeti…

Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
