Izhodišča. Uporaba tridimenzionalne ultrazvočne preiskave (3D UZ) v oftalmologiji predstavlja pri nas novo klinično preiskavo, ki nam daje dodatne možnosti UZ diagnostike. V naslednjem prispevku želimo prikazati uporabo 3D UZ preiskave v oftalmologiji pri različnih boleznih in prikazati prednosti in pomanjkljivosti te metode v primerjavi s standardizirano ultrasonografijo. Bolniki in metode. V prispevku je zajetih 12 bolnikov, ki so bili hospitalizirani na Oddelku za očesne bolezni Splošne bolnišnice Maribor v obdobju od decembra 2002 do marca 2003, in pri katerih je bila poleg standardizirane ultrasonografije (2D UZ) narejena še 3D UZ preiskava. Preiskavo smo opravili pri bolniku z malignim melanomom žilnice, eksudativno makulopatijo, subhorioidalno krvavitvijo, ftizi zrkla po poškodbi, pri okvari vidnega živca po poškodbi, retrobulbarnem nevritisu, pri dveh bolnikih zaradi krvavitve v steklovino, pri dveh bolnikih zaradi uveitisa in pri dveh bolnikih zaradi odstopa mrežnice. Rezultati. Pri vseh bolnikih smo s standardizirano ultrasonografijo (2D UZ) potrdili ali postavili diagnozo ter nato pri vseh naredili še 3D UZ preiskavo. Pri bolnikih z eksudativno makulopatijo in odstopom mrežnice nismo našli prednosti te metode glede na standardizirano 2D UZ preiskavo, enako tudi ne pri obeh bolnikih z boleznijo in poškodbo vidnega živca. Pri dveh bolnikih s krvavitvijo v notranjost očesa, pri dveh z uveititsom in pri bolniku s subhorioidalno krvavitvijo so bile spremembe bolj vidne s 3D metodo. Prednost 3D UZ metode je bila pri bolniku z malignim melanomom žilnice, kjer smo lahko natančno določili umestitev, velikost in prostornino tumorja. Tudi v primeru ftize zrkla po poškodbi smo s 3D UZ metodo natančno določili velikost in prostornino zrkla in lažje ugootovili porušeno strukturo v njegovi notranjosti. Zaključki. 3D UZmetoda nam daje možnosti natančnega določanja tridimenzionalnih struktur. Naše prve izkušnje s 3D UZ metodo v oftalmologiji kažejo na njeno prednost pri določanju lokacije, velikosti in prostornine posameznih sprememb, kot so intraokularni tumorji in za določanje volumna in strukture očesa po poškodbi, kot je ftiza zrkla. Seveda je potrebno večje število preiskovancev, da bomo naše ugotovitve lahko potrdili.

Sekundarni naslov: Three-dimensional ultrasound examination in ophthalmology - initial experience in various eye disease
Sekundarni povzetek: Background. The use of three-dimensional (3D) ultrasonography in ophthalmology presents in our country a new clinical investigation, which give us a new ultrasound diagnostic possibilities in this field. The aim of this contribution was to present the use of 3D ultrasound examination in various ocular diseases and to find out advantages and disadvantages of this method in comparison with standard ultrasonography. Patients and methods. Twelve patients hospitalized at Department of Ophthalmology in Teaching Hospital Maribor were selected for 3D ultrasound examination in addition to 2D ultrasonography between December 2002 and March 2003. The examination was performed in patient with chorioidal melanoma, exudative maculopathy, subchorioidal hemorrhage, retinal detachment, phthysis of the eye after injury, optic nerve trauma, retrobulbar neuritis, in 2 patients with vitreous haemorrhages, in 2 patients with uveitis and in 2 patients with retinal detachment. Results. In all patients after standardized ultrasonography (2D), which already confirmed or determined the diagnosis, 3D ultrasonography was performed. In patients with exudative maculopathy and retinal detachment we found no advantages with this method. The same findings were also in patient with optic nerve disease and optic nerve trauma. In patient with vitreous hemorrhage and in patient with subhorioidal hemorrhage the changes were more evident with 3D ultrasonography. The real advantage of 3D ultrasonography was in patient with choroidal melanoma, where measurements of tumor heigh, volume and determination of tumor localisation were more accurate. Conclusions. 3D ultrasonography allows the precise assessment of three-dimensional structures. Our experiences with 3D ultrasonography in ophthalmology suggest advantages of this method for measurement of lenght, area and volume of ocular tumors, particularly malignant melanoma and for evaluation of structure, lenght and volume of traumatized eye, such is phthysis. A further study with larger number of patients is necessary to confirm our findings.
