To investigate the correlations between clinical findings and histopathologic changes in eyes with pterygium.This prospective study included 70 primary pterygia undergoing surgical excision. Prior to surgery, features of including extension over cornea, redness, fleshiness (based on obscuration underlying episcleral vessels), obliteration plica semilunaris were determined. Postoperatively, pterygium specimens examined by hematoxylin-eosin trichrome staining evaluate characteristics vascular...
Objective To evaluate the ability of contrast sensitivity (CS) to discriminate loss visual function in diabetic subjects with no clinical signs retinopathy relative that normal subjects. Research design and methods In this prospective cross-sectional study, we measured CS 46 a mean age 48±6 years, best-corrected acuity 20/20 retinopathy. The these was compared measurements control at four spatial frequencies (3, 6, 12, 18 cycles per degree) under moderate (500 lux) dim (less than 2...
Abstract Common killifish Fundulus heteroclitus were acclimated to ecologically relevant temperatures (5, 15 and 33°C) their maximum heart rate ( f Hmax ) was measured at each acclimation temperature during an acute warming protocol. Acclimation 33°C increased peak by up 32% allowed the beat rhythmically a 10°C higher when compared with 5°C. Independent of temperature, occurred about 3°C cooler than that first produced cardiac arrhythmias. Thus, previously published values for critical...
To compare visual outcomes and contrast sensitivity after wavefront-optimized or conventional photorefractive keratectomy (PRK) in myopic patients with without astigmatism.Vanak Eye Surgery Center, Tehran, Iran.Comparative case series.Patients low to moderate myopia astigmatism were allocated into 2 groups. The study group was treated PRK (Allegretto Wave Eye-Q software version 2.020 default treatment) the control group, (Technolas 217z). In all cases, treatments bilateral performed same...
To investigate whether autologous platelet-rich plasma (PRP) eye drops accelerate re-epithelialization of post-keratoplasty persistent corneal epithelial defects (PEDs).A total 34 eyes with PEDs after keratoplasty (24 penetrating and 10 deep anterior lamellar keratoplasty) that were refractory to conventional medical treatments treated PRP every 3 hours. prepared a low- high-speed centrifugation method final platelet counts 700,000-800,000 plt/μl. The mean treatment duration for complete was...
To evaluate the correlation of visual acuity and diabetic retinopathy stage using optical coherence tomography angiography metrics.In this prospective study, images patients with different stages were obtained. In images, size foveal avascular zone, central macular thickness, vessel density at superficial deep capillary layers macula measured. presence intraretinal cyst, disorganization retinal inner layer, ellipsoid zone external limiting membrane disruption evaluated. The associations...
To evaluate the macular thickness changes in diabetic edema after meal.In this prospective case series, thicknesses of patients with clinically significant (CSME) were measured 7 h fasting and repeated 2 breakfast.Thirty six eyes 20 evaluated. The mean central subfield (CST) maximum retinal (MRT) significantly decreased meal (mean change -10.3 ± 14.3 μm -13.1 12.7 μm, respectively, both P < 0.001). A decrease CST MRT values was found 23 (63.8%) 28 (77.7%) eyes, no eye had an increase...
Purpose To evaluate the effect of optical coherence tomography (OCT) grid decentration on macular thickness measurements in healthy subjects and patients with diabetic edema. Methods In this prospective study, 3D spectral-domain OCT images 51 eyes clinically significant edema 29 were assessed. each eye, Early Treatment Diabetic Retinopathy Study was evaluated for decentration. After adjustment, changes central subfield (CST) volume (CSV) recorded. Changes >1 μm >8.5 CST considered as...
To evaluate the retinal vascular response to hyperoxia in patients with diabetes at preclinical stage of diabetic retinopathy (DR) and quantify changes comparison normal subjects using optical coherence tomography angiography (OCTA). In this prospective study, 40 eyes 20 participants comprising 10 no (NDR) were recruited. OCTA images acquired resting position repeated after a hyperoxic challenge nasal mask connected reservoir bag supplying 100% oxygen rate 15 L per minute for 5 minutes. The...
To evaluate the effects of intravitreal ziv-aflibercept injections (IVZ) on subfoveal choroidal thickness (SCT) as well central macular (CMT) and best corrected visual acuity (BCVA) changes in eyes with center-involved diabetic edema (CI-DME).Fifty-seven 36 patients CI-DME were included this prospective interventional case series. Structural optical coherence tomography (OCT) enhanced depth imaging OCT performed at baseline followed by three monthly 1.25 mg IVZ injections. Changes SCT, CMT,...
In this randomized controlled trial, we assessed the effects of three consecutive intra-silicone oil (SO) injections methotrexate (MTX) on outcomes surgery for proliferative vitreoretinopathy grade C (PVR-C). Seventy-four eyes 74 patients with PVR-C were included. Of these, 37 assigned to MTX group and control group. Fourteen failed comply 6-month follow-up period. All underwent vitrectomy SO injection. group, 250 µg was injected into after at weeks 3 6 postoperatively. The primary outcome...
Glaucoma is characterized by the progressive degeneration of optic nerve head (ONH) and retinal ganglion cells (RGCs). RGCs can be divided into basic regions, including axon synapse, dendritic arbor, cell body (1). These compartments independently affected processes cause damage ONH (1,2).
