Sažetak
Uvod/Cilj. Jedna od najpouzdanijih metoda za merenje strukturnih promena kod glaukoma je spektralna optička koherentna tomografija - spectral domain optical coherence tomography (SD-OCT). Cilj rada bio je da se izmeri debljina peripapilarnih retinalnih nervnih vlakana (RNFL) uz pomoć SD-OCT, kao i da se utvrdi koji je sektor u pomenutom prostoru najosetljiviji na glaukomatozno oštećenje. Metode. U studiju je bilo uključeno ukupno 153 očiju 93 bolesnika sa potvrđenim primarnim glaukomom otvorenog ugla (POAG). Svim bolesnicima urađen je kompletan oftalmološki pregled, uključujući dodatno kompjuterizovano vidno polje i merenje peripapilarnih RNFL pomoću SD- OCT. Bolesnici su bili podeljeni u tri podgrupe: rani, srednji i odmakli stepen glaukoma (prema vrednostima MD na vidnom polju). Rezultati. Rezultati su predstavljeni kao srednje vrednosti ukupne debljine RNFL za celu grupu i podgrupe, kao i preko 4 cirkularna i 12 linearnih sektora. Srednja vrednost RNFL iznosila je 74,95 + 14,51 μm. Najdeblji je bio donji kvadrant (92,78 + 25,84 μm), potom gornji (88,82 + 22,04 μm), nazalni (64,31 + 11,67 μm) i temporalni (54,02 + 12,76 μm) što je značajna razlika (x2 = 273,36, DF = 3, p < 0,001). Poređenjem debljine RNFL kod ranog glaukoma u odnosu na srednji i odmakli stadijum, najsenzitivniji su bili gornji i donji kvadrant kao i sektor od 5 do 7 sati. Najtanja je bila pozicija na 9 sati (46,99 + 13,28 μm), a najdeblja na 6 sati (102,63 + 34,12 μm). Zaključak. Debljina peripapilarnih RNFL i stepen glaukoma su obrnuto proporcionalni: veći stepen oštećenja podrazumeva tanja peripapilarna RNFL.
