Abstract
Cilj rada: Akutna simptomatska ablacija stražnje hijaloidne membrane definirana je kao ablacija stražnje hijaloidne membrane praćena novonastalim simptomima u trajanju od mjesec dana i pronalaskom Weissova prstena tijekom kliničkog pregleda. Sklona je komplikacijama od kojih su najčešće rupture mrežnice i krvarenja u staklovinu. Cilj rada je utvrditi pouzdanost ultrazvuka u otkrivanju mrežničnih ruptura u pacijenata sa akutnom simptomatskom ablacijom stražnje hijaloidne membrane. ----- Materijali i metode: Retrospektivnim pregledom medicinske dokumentacije bolesnika pregledanih na Klinici za očne bolesti Kliničke bolnice "Sveti Duh" između lipnja 2012. i lipnja 2013. godine u istraživanje je uključeno sedamdeset i pet bolesnika sa simptomima akutne ablacije stražnje hijaloidne membrane. U studiju su uključeni samo pacijenti kojima je transpalpebralni ultrazvuk oka i orbite te pregled fundusa učinjen odmah i nakon 6 tjedana. ----- Rezultati: Ultrazvučnim pregledom je u 13 (17%) bolesnika otkrivena membranozna lezija ultrazvučnih karakteristika rupture mrežnice. Kliničkim pregledom dijagnoza je potvrđena u 8 od 13 bolesnika. U 62 od 75 bolesnika nisu nađene rupture mrežnice niti ultrazvučno niti kliničkim pregledom. Osjetljivost ultrazvučnog pregleda bila je 100% (95% IP[interval pouzdanosti] 60-100), specifičnost 92%, pozitivna prediktivna vrijednost 62% (95% IP 32-85), a negativna prediktivna vrijednost 100% (95% IP 93-100). ----- Zaključak: Ultrazvuk je pouzdana i točna metoda za otkrivanje rupture mrežnice u akutnoj simptomatskoj ablaciji stražnje hijaloidne membrane. S obzirom na visoku osjetljivost i negativnu prediktivnu vrijednost, negativan rezultat na B-scan ultrazvuku isključuje prisutnost rupture mrežnice s visokim stupnjem sigurnosti.
Abstract (english)
Aims of study: Acute symptomatic posterior vitreous detachment (ASPVD) is defined as PVD (posterior vitreous detachment) accompanied with a new onset of symptoms within one month of presentation and Weiss ring found during clinical examination. It is prone to complications, among which most common are retinal tears and vitreous hemorrhage. The aim of the study was to check ultrasound reliabilty in detecting retinal tears in patients with ASPVD. ----- Materials and methods: By retrospective review of medical documentation of patients who were examined at the Department of Ophthalmology, University Hospital "Sveti Duh" between June 2012 and June 2013, seventy-five patients with symptoms of ASPVD were included in the study. Only patients who were examined with transpalpebral ultrasound of the eye and the orbit followed by fundus examination initially and in 6 weeks period were included in the study. ----- Results: In 13 (17%) patients membranous lesion with ultrasound characteristics of retinal tear was detected. Clinical examination of the fundus confirmed the diagnosis in 8/13 patients. In 62/75 patients neither ultrasound nor clinical examination revealed retinal tear. Sensitivity of ultrasound examination was 100% (95% CI [confidence interval] 60–100), specificity 92%, positive predictive value 62% (95% CI 32-85), and negative predictive value 100% (95% CI 93-100). ----- Conclusion: Ultrasound is a reliable and accurate method for retinal tears detection in ASPVD. Given the high sensitivity and negative predictive value, negative result on B-scan ultrasound excludes the probability of the retinal tear with a high degree of certainty.
