78 Szemészet The blood supply of the glaucomatous eye before and after trabulectomy Burka, Gabriella, Reichard, Lilla, Szigeti, Zoltán, Csoma, Éva Dept, of Ophthalmology, St. John ’s Hospital, Budapest Aim: To determine whether the circulation indicators of the central retinal artery and vein and a. ophthalmica change following trabeculectomy, in cases of decompensated glaucoma. Method: Using a Kretz ultrasonic imaging instrument with a 7.5 MHz linear head, we performed a colour Doppler examination at one day, seven days, and ninety days after trabeculectomy. We examined the circulations in a. ophthalmica and a. centralis retinae in the eyes of 12 patients, 10 with open-angle glaucoma and 2 with closed-angle glaucoma. Results: With closed-angle glaucoma, the field of vision improved with the decrease of the intraocular pressure, the RI factor of the arterial flow also decreased and the circulation improved. With open-angle glaucoma patients the lowering of intraocular pressure resulted in improvement only in half the cases, and there was one case where the functions degraded in spite of the intraocular pressure having decreased. Conclusions: While the increase of intraocular pressure is a common symptom of closed-angle and open-angle glaucoma, these are in fact fundamentally different illnesses. A filtration-mesh operation is able to preserve vision in only half of the cases. Első tapasztalatok optikai koherens tomográfiával a glaucoma vizsgálatában Gáspár Ákos, Dekov Annamária Semmelweis Egyetem AOK, II. sz. Szemészeti Klinika, Budapest Cél: A Zeiss Humphrey 2010 típusú optikai koherens tomográf glaucomás betegek vizsgálatára alkalmas programjainak bemutatása. Betegek és módszer: Különböző betegségtartamú glaucomás betegek papilláján és papilla körül idegrostrétegen végzett mérések. Eredmények: A módszer az állapot rögzítésére alkalmas, amely újszerű analízist tesz lehetővé a glaucomás szöveti károsodás kimutatásában. Következtetés: Longitudinális megfigyelést lehetővé tevő noninvazív módszer a betegség progressziójának követésére. First experiences with optical coherence tomography in examination of glaucoma Gáspár, Ákos. Dekov, Annamária 2"J Dept, of Opthalmology, Medical Faculty, Semmelweis University, Budapest Aim: To present some applications of the Zeiss Humphrey System Optical Coherence Tomography 2010 instrument, used in the case of glaucomatous patients. Patients and methods: Measurements of optic disc excavation and the peripapillary nerve fibre layer were performed on patients who had suffered from glaucoma for various different periods of time. Results: The method is useful in detecting the progression of the disease and provides a new type of measurement for use in research on the histological deterioration caused by glaucoma. Conclusion: This new non-invasive method is suitable for longitudinal observation of the progression of glaucoma in patients. 2002 augusztus 30.
