INTRODUCCIÓN: La aplicación de la microscopia confocal in vivo en la evaluación de la bula, después de la cirugía filtrante de glaucoma, permite relacionar las características morfológicas con la función de la bula de filtración y el tiempo de cirugía. Este estudio se propone describir los hallazgos de la microscopia confocal en las bula de filtración funcionales y afuncionales. MÉTODOS: Se realizó un estudio descriptivo longitudinal; se distribuyeron los pacientes en: grupo A (83 bulas funcionales) y grupo B (17 bulas afuncionales). Se evaluaron las características clínicas de las bulas de filtración y la tonometría de aplanación de Goldman. La microscopia confocal se realizó a los tres meses de la cirugía con el módulo corneal Rostock HRT II. La edad media fue de 63 años. El sexo femenino correspondió al 59 % (n= 49) y el glaucoma primario de ángulo abierto al 80 %. La tensión ocular media en las bulas de filtración funcionales fue de 14,1 mm Hg y en las bulas afuncionales de 28,8 mm Hg. RESULTADOS: En las bulas funcionales se encontraron en la microscopia confocal numerosos microquistes epiteliales, malla estromal porosa similar al colágeno, espacios quísticos no encapsulados, mínima vascularización y ausencia de vasos conjuntivales tortuosos. Las bulas afuncionales se caracterizaron por la presencia de escasos microquistes epiteliales, estroma denso e hiperreflectivo, numerosos espacios estromales quísticos encapsulados y vasos conjuntivales tortuosos. CONCLUSIONES: La microscopia confocal permite caracterizar una bula filtrante funcional de una bula afuncional, por lo que su combinación con las características clínicas de la bula de filtración constituye un criterio importante para evaluar el éxito de la cirugía.
INTRODUCTION: The use of in vivo confocal microscopy to evaluate the bleb after a filtering surgery of glaucoma allows relating the morphological characteristics to the function of the filtering bleb and the time of surgery. This study was aimed at describing the findings of confocal microscopy in functioning and failing filtering blebs. METHODS: A longitudinal descriptive study was conducted in which the patients were divided into two groups : group A (83 functioning blebs) and group B (17 failing blebs). The clinical characteristics of the filtering blebs together with Goldman´s applanation tonometry were evaluated. Confocal microscopy was performed three months after the Rostock HRT II corneal module surgery. The average age was 63 years. Females predominated with 59% (n= 49) and GPAA was at 80 %. Mean ocular pressure in the functioning filtering blebs was 14,1 mm Hg and in the failing blebs was 28,8 mm Hg. RESULTS: Confocal microscopy showed many epithelial microcysts, porous stromal mesh similar to collagen, non-encapsulated cystic spaces, minimal vascularization and no twisted conjunctival vessels. CONCLUSIONS: In vivo confocal microscopy makes it possible to differentiate a functioning filtering bleb from a failing bleb so the combination of this microscopy with the clinical characteristics of the filtering bleb is an important criterion for assessing a successful surgery.
