Abstract		Background. A change in retinal thickness caused by several ocular diseases can be measured quantitatively by the retinal thickness analyser (RTA). The principle of RTA is based on projecting a laser slit (540 nm) onto the retina and viewing its intersection with the retina. The separation between the reflections from the vitreoretinal and the chorioretinal interface is a measure of the retinal thickness. By scanning the posterior pole and/or peripapillary retina, the intersections of the laser slit with the retina are presented as multiple optical cross sections and as colour-coded retinal thickness maps. Conclusions. In the article the application of the new method in glaucoma and other retinal diseases is presented. Scanning RTA is a non-invasive method and provides quantitative information that may be useful in the diagnosis and monitoring of glaucoma and a variety of retinal diseases in clinical practice.
Summary		Izhodišča. Spremembe v debelini mrežnice, ki jih povzročijo različne bolezni, lahko kvantitativno določimo z analizatorjem debeline mrežnice (RTA). Naprava za izvor svetlobe uporablja laserski žarek (540 nm), ki ga projicira na mrežnico, analizira pa žarek, ki se odbije z mrežnice. Razdaja med odbojem žarka z vitreoretinske površine in horioretinske površine je premosorazmerna z debelino mrežnice. RTA skenira mrežnico na zadnjem polu in/ali v peripapilnem delu ter odboje prikaže kotsvetlobne špranje in kot barvno kodirano sliko debeline mrežnice. Zaključki. V prispevku smo prikazali možnosti uporabe nove metode pri glavkomu in nekaterih boleznih mrežnice. Preiskava je neinvazivna in nam kvantitativno posreduje podatke, ki so lahko koristni pri diagnostiki in spremljanju očesnih bolezni v klinični praksi.
