Do biometric parameters improve the quality of optic nerve head measurements with spectral domain optical coherence tomography?
Funding Information: A part of the study data have been presented as a free paper oral presentation ā Clinical quality assessment of optic nerve head measurements with spectral domain optical coherence tomographyāpreliminary resultsā in 118. Congress of the DOG (German Society of Ophthalmology) 2020. Publisher Copyright: Ā© 2022, The Author(s).Background: Spectral domain optical coherence tomography (SD-OCT) is a widely applied non-invasive technique for evaluating optic nerve head parameters. The aim of this study was to evaluate the impact of biometric parameters such as the spherical equivalent (SE) and the anterior corneal curvature (ACC) on the peripapillary retinal nerve fiber layer (pRNFL), Bruchās membrane opening (BMO), and the minimum rim width (MRW) measurements performed by spectral domain optical coherence tomography (SD-OCT) in glaucomatous and healthy eyes. Methods: In this cross-sectional, caseācontrol prospective pilot study, the glaucoma group consisted of 50 patients with previously diagnosed and treated glaucoma and one healthy group of 50 subjects. Two consecutive examinations of pRNFL, BMO, and MRW with SD-OCT for every patient were performed without ACC and objective refraction (imaging 1) and with them (imaging 2). Results: The interclass correlation coefficient (ICC) reflected high agreement between imaging 1 and imaging 2 in both groups. The ICC in the glaucoma and healthy groups for pRNFL (0.99 vs. 0.98), BMO (0.95 vs. 0.97), and MRW (1.0 vs. 1.0) was comparable. Conclusions: Our preliminary data from a small number of eyes showed that the measurements of pRNFL, MRW, and BMO reflected high agreement between both imaging techniques with ACC and objective refraction and without these parameters in subjects with a refractive error up to Ā± 6.0 diopters. Further studies with participants with higher refractive error are necessary to evaluate the impact of biometric parameters such as SE and ACC on measurements with SD-OCT.publishersversionPeer reviewe
LU 76. konference: tÄzes un raksti
KrÄjumu veido LU Filozofijas un socioloÄ£ijas institÅ«ta pÄtnieku Latvijas UniversitÄtes 76. starptautiskÄs zinÄtniskÄs konferences sekciju darbÄ 2018. gada 15. un 16. februÄrÄ« nolasÄ«to prioritÄrajam projektam āKritiskÄ domÄÅ”ana, inovÄcija, konkurÄtspÄja un globalizÄcijaā veltÄ«to referÄtu tÄzes, kÄ arÄ« vairÄki raksti, kuri tapuÅ”i uz Å”ajÄ konferencÄ nolasÄ«to referÄtu pamata.
LU FSI pÄtniekiem konference bija ne tikai atskaite par otrajÄ pÄtniecÄ«bas gadÄ projektÄ paveikto, bet tajÄ pÄtnieki diskutÄja arÄ« par to, kÄ paplaÅ”inÄt pÄtÄmo tÄmu loku, pievÄrÅ”oties vairÄkiem Latvijas sabiedrÄ«bai aktuÄliem jautÄjumiem. PiemÄram, ja Filozofijas un socioloÄ£ijas institÅ«ta filozofi projekta 1. posma noslÄguma seminÄrÄ pÄrsvarÄ diskutÄja par kritiskÄs domÄÅ”anas konceptu un tÄs lietojuma iespÄjÄm, tad LU 76. konferencÄ jau iezÄ«mÄjÄs noturÄ«ga interese par kritiskÄs domÄÅ”anas un medijpratÄ«bas sasaisti, kas 2018. gada beigÄs noslÄdzÄs ar ekspertu seminÄru cikla organizÄÅ”anu sadarbÄ«bÄ ar Eiropas Kopienas pÄrstÄvniecÄ«bu LatvijÄ. VairÄki pÄtnieki pievÄrsÄs jautÄjumam par inovÄcijas iespÄjÄm humanitÄrajÄs zinÄtnÄs utt.
Konferences referÄti atspoguļoja dažÄdas pieejas un metodoloÄ£ijas, sniedzot ieskatu vÄl nepabeigtajos pÄtÄ«jumos, bet tikai to norisÄ un pirmajos rezultÄtos. PÄtÄ«jumu gaitai lasÄ«tÄjs aicinÄts sekot turpmÄkajÄs LU FSI pÄtnieku zinÄtniskajÄs publikÄcijÄs
