Abstract

Purpose : To investigate the quantitative assessment of macular edema secondary to central or branch retinal vein occlusion with foveal thickness measurements by optical cohérence tomography (OCT). Material and methods : Thirty eight eyes of 38 cases examined between October 2000-May 2002, with central or branch retinal vein occlusion were included in the study. At initial examination and during follow-up examinations at 3-6 month intervals, complete ophthalmic examination was done, color fundus photographs were taken and fluorescein ângiography was performed. Foveal thickness measurements were taken in macular cross-section images obtained with optical coherence tomography. Control group included thirty-nine eyes of 33 healthy objects without eye pathology. Foveal thickness measurements were obtained from macular OCT images and compared with the values of study group. Results : At initial examination, there was sponge-like retinal swelling in 34 %, cystoid macular edema in 34 %, serous macular edema in 19.2 % and mixed edema in 12.8 % of 38 cases (11 of them had central, 27 of them had branch retinal vein occlusion). In the study group.the mean foveal thickness at initial examination (590.2 + 45 urn) was significantly higher than the mean value at last visit (403.1 + 53 urn). These values were also significantly higher than the mean foveal thickness in control group (177.1 + 19.4 urn). There was negative correlation between mean foveal thickness measurements and visual acuities at initial and final examinations. Conclusion : Optical coherence tomog-raphy is a useful technique for noninvasive, objective and quantitative assessment of macular edema secondary to retinal vein occlusions with foveal thickness measurements.

Özet

Amaç : Retina ven kök tıkanıklığı (RVKT), ve retina ven dal tıkanıklıklarında (RVDT) gelişen makula ödeminin, makula kalınlık ölçümleri yapılarak niceliksel olarak takibinde Optik Koherens Tomografi (OKT)'nin etkinliğini araştırmak Gereç ve Yöntem : Ekim 2000-Mayıs 2002 tarihleri arasında muayene edilerek retina ven kök veya ven dal tıkanıklığı saptanan 38 olgunun 38 gözü çalışma kapsamına alındı. Olguların tam oftalmolojik muayeneleri yapılarak renkli fundus fotoğrafları ve flöresein anjiografileri çekildi. OKT ile makuladan geçen kesitlerde fovea kalınlık ölçümleri yapıldı. 3-6 ay aralıklarla yapılan kontrol muayenelerinde fundus fotoğrafları çekilerek OKT ölçümleri tekrarlandı, gerekli durumlarda flöresein anjiografi uygulandı. Kontrol grubu olarak aynı tarihler arasında muayene edilerek herhangi bir göz patolojisi saptanmayan 33 sağlıklı bireyin 39 gözü değerlendirildi. Bu gözlerde de OKT ile elde edilen makula kesitlerinde fovea kalınlık ölçümleri yapıldı. Hasta ve kontrol grubunda elde edilen değerler birbirleriyle karşılaştırıldı. Bulgular : Ven tıkanıklığı (117 kök, 27'si dal) olan olgularda ilk muayenede OKT He saptanan makula ödemi, % 34 sünger benzeri, % 34 kistik, % 19.2 seröz, % 12.8 mikst ödem şeklindeydi. Ven tıkanıklığı grubunda ilk muayenede elde edilen ortalama fovea kalınlığı (590.2 + 45 um), son kontrolde elde edilen değerden (403.1 + 53 um) anlamlı olarak yüksekti. Bu değerler aynı zamanda kontrol grubunda elde edilen ortalama fovea kalınlığı değerinden de (177.1 + 19.4 um) anlamlı olarak yüksek bulundu. OKT ile ölçülen kalınlık değerleri, ilk ve son kontroldeki görme keskinlikleri ile ters korelasyon göstermekteydi. Sonuç : Optik koherens tomografi, retina ven tıkanıklığına bağlı makula ödeminde foveakalınlığı ölçümleri ile niceliksel olarak takibe olanak sağlayan, tekrar edilebilir ve invaziv olmayan objektif bir tanı yöntemidir.
