Estudio mediante biomicroscopia ultrasónica de pacientes intervenidos de esclerectomía profunda no perforante con implante supraciliar / An ultrasound biomicroscopy study after deep sclerectomy with supraciliary implant

OBJETIVO: Evaluar a pacientes 24 meses después de ser intervenidos mediante esclerectomía profunda no perforante (EPNP) con implante supraciliar y determinar la existencia de factores predictivos de la eficacia de la técnica mediante la exploración biomicroscópica (BMU). MATERIAL Y MÉTODOS: Se incluyen 26 ojos de 23 pacientes explorados con UBM 24 meses después de ser intervenidos mediante EPNP con implante de hema supraciliar. RESULTADOS: Se ha encontrado un descenso significativo de la presión intraocular (PIO) de 25,6 ± 6,4 mmHg a 16,2 ± 3,4 mmHg y en el número de medicaciones antiglaucomatosas de 2,5 ± 0,6 por paciente a 0,5 ± 0,5 (p < 0,001). No se evidenciaron cambios significativos en la agudeza visual. Mediante BMU no se ha podido correlacionar la PIO con el diámetro horizontal (r = −0,05; p = 0,71) ni vertical (r = −0,1; p = 0,63) del lago intraescleral, su altura (r = 0,28; p = 0,25) ni volumen (r = −0,08; p = 0,79), el grosor de la MBTD (r = −0,07; p = 0,73) ni su longitud (r = 0,39; p = 0,13), la presencia de ampolla filtrante (p = 0,3) ni de un área hipogénica en el espacio supracoroideo (p = 0,2). CONCLUSIONES: La inserción del implante de hema en el espacio supraciliar durante la cirugía no perforante del glaucoma es segura y efectiva en el glaucoma de ángulo abierto (GAA) pero no hemos podido establecer factores

OBJETIVE: To evaluate patients 24 months after deep sclerectomy (DE) with supraciliary implant, and identify any predictive success factors by examination with ultrasound biomicroscopy (UBM). MATERIAL AND METHODS: This study included 26 eyes of 23 patients evaluated by UBM 24 months after a deep sclerectomy with a supraciliary hema implant. RESULTS: There was a significant reduction in intraocular pressure (IOP), changing from a preoperative mean of 25.6 ± 6.4 mmHg to a postoperative mean of 16.2 ± 3.4 mmHg (P<.001). The number of preoperative glaucoma medications also decreased from 2.5 ± 0.6 drugs per patient to 0.5 ± 0.5 (P<.001). No change was observed in the best-corrected visual acuity. The anatomical characteristics of the surgical area, and its relationship with IOP were examined using UBM. There was no correlation between the level of IOP at the time of UBM and the horizontal (r=−.05: P=.71) and vertical diameter (r=−.1; P=.63), the height (r=.28; P=.25) and the volume of intrascleral space (r=−.08; P=.79), the thickness (r=−.07;P=.73) and the length (r=.39; P=.13) of trabeculo-Descemet's membrane (TDM), the presence of filtering bleb (P=.30) and the hypoechoic area in the supraciliary space (P=.24). CONCLUSIONS: The insertion of a hema implant in the supraciliary space is an effective and safe surgery for patients with open angle glaucoma (OAG). No predictive success factors for supraciliary implant were found using the UBM study

Bevacizumab intravítreo en el tratamiento de la neovascularización subretiniana secundaria a rotura coroidea / Use of intravitreal bevacizumab for the treatment of choroidal neovascularization secondary to choroidal rupture

Caso clínico: Paciente varón de 28 años que presenta rotura coroidea y hemorragia macular postraumáticas de 24 horas de evolución acude al servicio de urgencias. Se realizó desplazamiento neumático de la hemorragia mediante inyección intravítrea de C3F8 y activador tisular del plasminógeno (rTPA), consiguiéndose la reabsorción de la hemorragia y mejora de la agudeza visual (AV). Al cabo de 3 meses, el paciente acude por empeoramiento de la visión con metamorfopsia, diagnosticándose de neovascularización (NVC) yuxtafoveal en la zona de la rotura, que se trata con una inyección de bevacizumab intravítreo. Un año después, la NVC permanece inactiva y la AV se mantiene en 0,5. Discusión: La inyección intravítrea de bevacizumab representa una nueva forma efectiva de tratamiento de la NVC postraumática. A diferencia de lo descrito en otras etiologías, la NVC secundaria a rotura coroidea en nuestro paciente requirió solamente una dosis de Avastin® para su inactivación, en un periodo de seguimiento de un año(AU)

Case report: A 28 year-old male attended our Emergency Department with a traumatic choroidal rupture and macular haemorrhage. After pneumatic displacement of the haemorrhage with C3F8 and tissue plasminogen activator, the haemorrhage was reabsorbed and visual acuity (VA) improved. Three months later the patient presented with decreased VA and a juxtafoveal choroidal neovascularisation (CNV) that was treated with intravitreal bevacizumab. One year after a single bevacizumab injection the CNV remained inactive, with a final VA of 0.5. Discussion: Intravitreal bevacizumab injection is a new and effective treatment for traumatic CNV. In our patient, in contrast to other aetiologies, the CNV needed no more than one Avastin® injection to be inactivated, after one year of follow-up(AU)

Biomicroscopia ultrasónica en esclerectomía profunda no perforante con un nuevo implante acrílico / Ultrasound biomicroscopy in deep sclerectomy with a new acrylic implant

Objetivo: Describir los hallazgos del examen con biomicroscopía ultrasónica (BMU) de pacientes operados de facoesclerectomía profunda no perforante con un nuevo implante acrílico (Esnoper®). Sujetos, materiales y métodos: Exploración con BMU 12 meses después de facoesclerectomía profunda no perforante en tres pacientes con glaucoma crónico de ángulo abierto. Resultados: Tras un año de seguimiento, los tres pacientes presentan presiones intraoculares menores de 15 mmHg sin tratamiento. En todos ellos, existe un lago intraescleral demostrable por BMU, donde es visible el implante hiperecogénico. Conclusiones: El nuevo implante no reabsorbible ha sido eficaz a medio plazo en esta serie de casos. La información aportada por BMU ayuda a comprender el mecanismo de acción de la cirugía no perforante

Objective: To describe the ultrasound biomicroscopic (UBM) characteristics seen in patients who have undergone deep phaco-sclerectomy with a new acrylic implant (Esnoper®). Subjects, material and methods: UBM exploration was performed 12 months after deep phacosclerectomy in three patients with chronic open angle glaucoma. Results: One year after surgery, all three patients had intraocular pressure levels under 15 mmHg and were on no treatment. All of them had an intrascleral space in UBM, in which the hyperechogenic implant was visible. Conclusions: The new non-absorbable implant has proven to be effective in these cases. Information provided by UBM is useful and assists in understanding the mechanism of action of deep sclerectomy
