Detection of Torque Teno Virus (TTV) and TTV-Like Minivirus in patients with presumed infectious endophthalmitis in India
2020
Human anelloviruses (Torque Teno Virus (TTV) and TTV Like Mini Virus (TLMV)) are now being reported at a high prevalence across the world, with a controversial disease-inducing potential. The aim of this study was to investigate the role of these anellovirus in vitreous of patients with presumed infectious endophthalmitis. After informed consent, vitreous fluid from patients with endophthalmitis (n = 103) and non-infectious pathologies (n = 102) were analyzed for the presence of TTV and TLMV DNA by qPCR with the limit of quantification defined as 100 copies per reaction. Among the patients clinically diagnosed with endophthalmitis, 29 of the 40 culture proven samples (72.5%) and 42 out of 6…
Vital dyes in macular hole surgery
2021
Currently, surgical techniques, such as internal limiting membrane peeling, are used widely for macular holes, macular puckers, epiretinal membranes, diabetic macular edema, retinal detachment, retinal vein occlusions, vitreomacular traction, optic pit maculopathy, and Terson syndrome. This study aimed to highlight any differences regarding visual acuity and ocular tomography coherence changes after staining the internal limiting membrane with dilutions of Brilliant Blue G vs. lutein/zeaxanthin-based dyes. This study involved 30 eyes of 30 patients who had undergone posterior pole vitrectomy for idiopathic stage 4 macular hole. The study lot was divided in two subgroups, 15 eyes colored wit…
Modified Vitrectomy Technique for Phakic Rhegmatogenous Retinal Detachment with Intermediate Break
2018
Purpose. To evaluate the effects of a modification of the traditional 25-gauge pars plana vitrectomy technique in the treatment of uncomplicated macula-on rhegmatogenous retinal detachment (RRD) with intermediate retinal break(s) and marked vitreous traction in the phakic eye. Methods. Prospective, noncomparative, and interventional case series. All consecutive phakic eyes with primary uncomplicated macula-on RRD with intermediate retinal break(s) and marked vitreous traction, with at least 1 year of postoperative follow-up, were enrolled. In all eyes, “localized 25-gauge vitrectomy” under air infusion with localized removal of the vitreous surrounding the retinal break(s), in association w…
CORRELATION OF OPTICAL COHERENCE TOMOGRAPHY PATTERN AND VISUAL RECOVERY AFTER VITRECTOMY WITH SILICONE OIL FOR RETINAL DETACHMENT
2006
PURPOSE: To assess prospectively the features of the macular surface in silicone oil-filled eyes after surgery by analyzing whether silicone oil affects optical coherence tomography (OCT) measurements and their reproducibility and whether a statistical correlation exists between postoperative best-corrected visual acuity (BCVA) and foveal thickness measured by OCT. METHODS: Twenty eyes of 20 patients underwent vitrectomy with silicone oil tamponade for retinal detachment. After vitrectomy, complete ophthalmic examination including determination of BCVA and OCT was performed to quantify the visual recovery and the foveal thickness. RESULTS: Ophthalmoscopy revealed that the retina appeared to…
Long-term results of surgical treatment of high myopia with Worst-Fechner intraocular lenses
1995
Abstract This retrospective study evaluated the results in 90 eyes that had a minus-power anterior chamber intraocular lens implanted to correct high myopia. Preoperative myopia ranged from −7.00 to −24.00 D. Postoperative spherical equivalent was −0.50 D; 80.5% of eyes were within 1.00 D of emmetropia. Two years postoperatively, no cataract formation, retinal detachment, glaucoma, or significant endothelial damage had occurred. We conclude that minus-power lenses can rapidly, safely, and predictably correct high myopia in phakic patients.
Elevated protein carbonyl and HIF-1α levels in eyes with proliferative diabetic retinopathy.
2013
Purpose: To evaluate the role of protein carbonyls and hypoxia inducible factor-1a (HIF-1a) in diabetic eyes with proliferative diabetic retinopathy (PDR). Methods: Prospective consecutive controlled observational study was performed. Vitreous samples were collected at the start of the 3-ppp vitrectomy. Protein carbonylation analysis was performed by Western blotting with antibody against 2,4-Dinitrophenol (anti-DNP), following derivatization of protein carbonyls with 2,4 Dinitrophenylhydrazine (DNHP). Protein carbonylation was quantified by scanning densitometry analysis and relativized to the total amount of protein into the ponceau staining of membranes. Vitreous HIF-1 a was determined w…
Incidence of Retinal Detachment in Germany: Results from the Gutenberg Health Study
2020
<b><i>Purpose:</i></b> To investigate the incidence of retinal detachment in the German population and to assess potential risk factors. <b><i>Methods:</i></b> The Gutenberg Health Study is a population-based cohort study in Mainz, Germany, including subjects (<i>n</i> = 15,010) with an age range from 35 to 74 years at baseline examination. Study participants underwent a comprehensive ophthalmological examination including distant-corrected visual acuity, refraction and slit-lamp examination at baseline examination. A computer-assisted telephone interview was conducted after 2.5 and 5 years, and health events were recorded. The 5-y…
ACUTE VISION LOSS AS THE ONLY SIGN OF LEUKEMIA RELAPSE.
2016
Purpose To report a case of unilateral exudative retinal detachment as the sole presentation of relapsing B-type lymphoblastic leukemia in a 35-year-old man after 3 years of remission. Methods Case report. Results A 35-year-old man in complete remission of high-risk type B acute lymphoblastic leukemia (ALL-B) presented with acute vision loss in his left eye. Exudative retinal detachment was diagnosed at initial evaluation. Hematological and ocular studies were performed. Although there was no evidence of blood, cerebrospinal fluid, or bone marrow disease relapse, transvitreal retinochoroidal cytology identified the infiltration of lymphoblastic leukemic B cells with t(12:21) translocation a…
Uveal effusion syndrome complicated by anterior ischemic optic neuropathy
1995
We report on a case of idiopathic uveal effusion syndrome complicated by AION. To our knowledge such an association hasn't been previously described. We suggest that scleral thickening caused obstruction of vortex veins followed by uveal effusion and compression of posterior ciliary arteries within their intrascleral tract, leading to AION. Nevertheless it can't be excluded that AION was the result of mechanical compression on ciliary vessels of optic disc by choroidal detachment. © 1996, Kluwer Academic Publishers. All rights reserved.
