ABSTRACT

OBJETIVO: Comparar a espessura corneana central (ECC), a densidade (DCEC) e a área média (ACM) das células endoteliais corneanas centrais após trabeculectomia (TREC) com e sem mitomicina C (MMC). MÉTODOS: Estudo prospectivo. Foram avaliados 29 olhos divididos em dois grupos: TREC com e sem MMC. Realizaram-se os seguintes exames pré-operatoriamente e três e seis meses após a TREC: paquimetria ultra-sônica e microscopia especular de não-contato. RESULTADOS: As variações da ECC, DCEC e ACM dos olhos submetidos a TREC com MMC foram, respectivamente: - 11,9±25,7 µm, -169,5±145,3 células/mm² e 42,5±33,4 µm² (três meses); - 7,5±28,1 µm, - 220,6±200,2 células/mm² e 31,5±65,3 µm² (seis meses). As variações da ECC, DCEC e ACM dos olhos submetidos a TREC sem MMC foram, respectivamente: - 13,9±16,7 µm, 200,8±155,4 células/mm² e 34,6±52,4 µm² (três meses); - 10,2±15,6 µm, - 277,6±195,7 células/mm² e 34,3±41,0 µm² (seis meses). CONCLUSÃO: TREC realizada com MMC, quando comparada a TREC sem MMC, não acarretou maior redução da DCEC central.Também não houve variação na ECC e na ACM nos dois grupos, após seis meses de seguimento.


PURPOSE: To assess comparatively the central corneal thickness (CCT), the central corneal endothelial cells density (CECD) and mean area (CECAA), of patients who underwent trabeculectomy (Trab) with or without mytomicyn C (MMC). METHODS: Prospective study. Twenty-nine eyes were divided in two groups: Trab with or without MMC. Ultrasonic pachymetry and non-contact specular microscopy were performed pre-operatively and three and six months after Trab. The mean value of the CECD and the low value of the CCT were used. RESULTS: In the group of Trab with MMC, the variations of the CCT, CECD and CECAA values were, respectively: - 11.9±25.7 µm, - 169.5±145.3 cells/mm² and 42.5±33.4 µm² (three months); - 7.5±28.1 µm, - 220.6±200.2 cells/mm² and 31.5±65.3 µm² (six months). In the group of Trab without MMC, the variations of the CCT, CECD and CECAA values were, respectively: - 13.9±16.7 µm, - 200.8±155.4 cells/mm² and 34.6±52.4 µm² (three months); - 10.2±15.6 µm, - 277.6±195.7 cells/mm² and 34.3±41.0 µm² (six months). CONCLUSION: After six months of follow-up, there was no difference in the variations of CCT, CECD and CECAA when Trab with MMC was compared with Trab without MMC.
