Espolonectomía: una nueva modificación de la esclerectomía profunda no perforante / Spurectomy: A novel modification of non-penetrating deep sclerectomy

Objetivos Evaluar los resultados de una nueva modificación de la esclerectomía profunda no perforante (EPNP) denominada espolonectomía. Métodos Estudio retrospectivo no aleatorizado y comparativo que incluyó 98 ojos (grupoA) operados con espolonectomía, que consiste en la combinación de la escisión del espolón escleral con EPNP. El grupo control (B) incluyó 53 ojos operados con EPNP clásica. Durante 12meses se estudiaron la presión intraocular (PIO), los medicamentos antiglaucomatosos que requirieron y las complicaciones. Resultados La PIO media disminuyó de 25,69±8,11 preoperatoria a 15,73±4,16mmHg después de la cirugía en el grupoA (p<0,001). En el grupoB disminuyó de 26,66±5,93 preoperatoria a 18,19±5,93mmHg postoperatoria (p<0,001). Las diferencias entre grupos de la PIO postoperatoria fue estadísticamente significativa (p<0,001). A los 12meses después de la cirugía, el 13,27 y el 52,83% de ojos en los gruposA yB requirieron tratamiento antihipertensivo tópico (p<0,001). La tasa de éxito absoluto después de la cirugía fue del 87,5 y del 47,17% en los gruposA yB, con una tasa significativamente mayor de éxito relativo en el grupoB (p<0,001). No hubo diferencias significativas entre los grupos en la tasa de complicaciones (p=0,960). La complicación postoperatoria más frecuente fue la microperforación de la membrana trabeculo-descemética en ambos grupos. Conclusiones La espolonectomía es una técnica segura y eficaz en comparación con la EPNP convencional y parece una alternativa prometedora en el tratamiento quirúrgico del glaucoma, optimizando la eficacia del tratamiento y minimizando las complicaciones (AU)

Purpose To evaluate the outcomes of a novel modification of the non-penetrating deep sclerectomy (NPDS) approach for glaucoma management called spurectomy. Methods Observational comparative non-randomized retrospective study including 98 glaucomatous eyes of 76 patients operated on with the spurectomy technique consisting of the combination of the excision of the scleral spur with NPDS (groupA). A control group (groupB) including 53 glaucomatous eyes of 43 patients operated on with classical NPDS was also included. Changes in intraocular pressure (IOP) and medications required as well as complications were recorded in a 12-month follow-up. Results Mean IOP decreased from 25.69±8.11 preoperatively to 15.73±4.16mm Hg postoperatively in groupA (p<0.001). In groupB, mean IOP decreased from 26.66±5.93 preoperatively to 18.19±5.93mm Hg postoperatively (P<.001). Differences between groups in postoperative IOP was statistically significant (P<.001). At 12months after surgery, 13.27% and 52.83% of eyes in groupsA andB required topical antihypertensive therapy (P<.001). The rate of absolute success after surgery was 87.5% and 47.17% in groupsA andB, with significantly higher rate of relative success in groupB (P<.001). No significant differences among groups were found in the complication rate (P=.960). The most common postoperative complication was microperforation of the trabeculo-descemetic membrane in both groups. Conclusions Spurectomy is a safe and effective technique when compared with conventional NPDS and seems a promising alternative in the surgical management of glaucoma, optimizing the efficacy of the treatment and minimizing complications (AU)

[Estimation of the efficacy of deep sclerectomy in glaucoma surgery. One-year follow-up]. / Estimación de la eficacia de la esclerectomía profunda no perforante en el tratamiento quirúrgico del glaucoma al año de la cirugía.

PURPOSE: To evaluate the efficacy of deep sclerectomy in the surgical treatment of glaucoma one year after surgery. METHODS: 53 eyes of 43 patients (26 male, 27 female) with medically uncontrolled glaucoma of various types, were treated with deep sclerectomy surgery. RESULTS: The mean postoperative intraocular pressure (IOP) was 18.19 S.D. 5.22 mmHg., and the mean preoperative IOP was 26.66 S.D. 5.93 mmHg. We observed a statistically significant reduction in the IOP (p<0.05). Our success criteria were IOP lower than 21 mmHg with or without associated hypotensive medications, no advance in glaucomatous visual field defects and no advance in optic nerve cupping. This was achieved in 88.68% of the cases at 12 months follow-up. CONCLUSIONS: Deep sclerectomy is an efficient technique to control IOP, with few early post-operative complications.

Objetivo: Estimar la eficacia del tratamiento quirurgico del glaucoma mediante la técnica de esclerectomia protunda no perborante (E.P.N.P.) al año de la cirugía.Material y métodos: 53 ojos de 43 pacientes (26 varones, 27 mujeres), con diferentes tipos de glaucomas mal controlados médicamente, fueron sometidos a una esclerectomia protunda no perborante.Resultados: La presión intraocular (P.I.O.) media f¦nal fue de 18,19 D.E. 5,22 mmHg., comparada con la P.I.O. media preoperatoria de 26,66 D.E. 5,93 mmHg. Se observa una reducción de la P.I.O. estadisticamente significativa (p<0,05). Consideramos éxito cuando la P.I.O. era menor de 21 mmHg. Con o sin tratamiento médico hipotensor postoperatorio, y no avanzaban los defectos glaucomatosos en el campo visual y no avanzaba la excavación papilar; consiguiéndolo en el 88,68 por ciento de los casos a los 12 meses.Conclusiones: La esclerectomia profunda no perforante es una técnica eficaz para el control de la P.l.O., con pocas complicaciones.
