A Real-World Study of Dexamethasone Implant in Treatment-Naïve Patients with Diabetic Macular Edema: Efficacy and Correlation Between Inflammatory Bi…

2020

Purpose There has been an increasing clinical interest in specific retinal parameters as non-invasive biomarkers of retinal inflammation in diabetic macular edema (DME) that have been shown to have prognostic value, such as hyperreflective retinal fields (HRFs) and subfoveal neuroretinal detachment (SND). Methods We conducted a prospective, non-comparative study of treatment-naive patients with DME to evaluate the efficacy of a Pro Re Nata (PRN) regimen of intravitreal dexamethasone implant 0.7 mg (DexI, Ozurdex™). After administration, patients underwent subsequent injections according to PRN criteria in case of edema relapse, but not earlier than 4 months after the previous treatment. Pat…

Orbital Decompression for Endocrine Ophthalmopathy: The Endonasal Approach

1994

A surgical endonasal procedure is described to perform orbital decompression in patients suffering from ophthalmopathy in Grave's disease. The decompression technique employs removal of the lamina papyracea as an exclusive modality or in conjunction with a transmaxillary or lateral decompression approach. This present series contain 23 patients who underwent decompression over a 3-year period and were followed for at least 6 months postoperative. The results of decompression were assessed by measuring reduction in proptosis and visual acuity. All patients demonstrated improved visual acuity. Measuring retroplacement of the globe, the endonasal approach proved to equal the results obtained …

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…

Virskorekcijas pielietojamība tuvredzības progresijas novērtēšanā ortokeratoloģijas pacientiem

2022

Darbs ir uzrakstīts angļu valodā uz 93 lapaspusēm. Tas satur 49 attēlus, 24 tabulas un 95 atsauces uz literatūras avotiem. Šī darba mērķis ir pārbaudīt, vai virskorekcija ir derīga metode tuvredzības progresēšanas novērtēšanai ortokeratoloģijā. Hipotēze ir atrast lielākas izmaiņas gados jaunākiem pacientiem nekā pieaugušajiem, kā tas ir norādīts literatūrā. Pētījumā iekļauti 192 Eiropeīdās rases subjekti vecumā no 6 līdz 56 gadiem (vidēji 19,61±10,30). Izmantojot retrospektīvu analīzi, no objektīva BOZR kontaktlēcas parametra tiek iegūta virskorekcija (ORX). Jaunākiem cilvēkiem ir lielākas ORX vērtības, bet pieaugušajiem nav atšķirības (p<0,05). Vidēji tuvredzība progresēja par –0,18±0,44 D…

Redzes asuma treniņu efektivitāte

2018

Bakalaura darbs ir uzrakstīts angļu valodā uz 27. lappasspusēm, satur 12 attēlus, 1. tabulu un tajā ir atsauksmes uz 21. literatūras avotu. Darba mērķis ir novērtēt redzes asumu uzlabojošo treniņu efektivitāti. Viens no iemesliem pazeminātai redzei var būt palielināta tuvuma slodze, kā arī pazeminātas spējas veikt dažādus vizuālos uzdevumus. Trenējot šīs spējas, redzes sistēma labāk pielāgojas palielinātai tuvuma slodzei. Pētījumā piedalījās 24 bērni, kuriem tika doti dažādi redzes treniņi 3 mēnešu periodā. Redzes asums treniņu beigās būtiski uzlabojās (p<0.0001), salīdzinot ar treniņu sākumu. Vidējais uzlabojums bija 0,19 logMAR vienības. Dalībniekiem ar miopiju ametropijas lielums treniņu…
