RESUMO

We report a retrospective case series describing the feasibility and outcomes of combined 27-G minimally invasive vitrectomy surgery (MIVS) and Ahmed® Glaucoma Valve (AGV) placement. Four eyes of four patients underwent a combined MIVS using 27-G technology and AGV implantation with the tube placement in the vitreous cavity. Preoperative and postoperative data up to 12 months were collected including the type of glaucoma, intraocular pressure (IOP), glaucoma medications, and complications. All AGVs tubes were placed in the vitreous cavity using the same sclerotomy, although a slight wound enlargement was required. After one year, IOP and glaucoma medications were reduced (41.5 ±â€¯19.1-14.5 ±â€¯3.1 mmHg and from 3(3-3) to 1.5 (1.5-3.5). Three patients developed cystoid macular edema. The first-reported cases of combined MIVS-27-G and AGV showed a reduction of IOP and antiglaucoma medication. Placing the tube using the same sclerotomy location is feasible but a slight enlargement may be required.

RESUMO

RESUMEN Objetivo: Determinar los resultados del implante dispositivo de glaucoma de Ahmed en pacientes con glaucoma pediátrico refractario. Métodos: Se realizó un estudio de serie de casos en 15 pacientes (17 ojos) con glaucoma pediátrico refractario atendidos en el Servicio de Oftalmología Pediátrica del Instituto Cubano de Oftalmología "Ramón Pando Ferrer" de enero del año 2011 a enero de 2016, a quienes se les implantó una válvula de Ahmed y fueron seguidos por un periodo de 3 años. Se evaluaron la agudeza visual, la presión intraocular pre y posoperatoria, el éxito completo, el éxito calificado, las complicaciones y las reintervenciones. Resultados: La mediana de edad de los pacientes fue de 4,0 años y predominó el sexo masculino (58,8 por ciento). La media de la presión intraocular preoperatoria fue de 37,3 mmHg y disminuyó a 19,4 mmHg de manera significativa (p= 0,000) en el posoperatorio. El análisis de supervivencia global mostró una probabilidad acumulada de éxito completo de 94,1 por ciento al 1,5 mes, 70,6 por ciento a los 12 meses, 58,8 por ciento a los 18 meses, y 47,1 por ciento a los 24 y a los 36 meses. La de éxito calificado fue de: 94,1 por ciento a los 12 meses, 82,4 por ciento a los 18 meses, y 76,5 por ciento a los 24 y a los 36 meses. La frecuencia de complicaciones fue de 29,4 por ciento y la de reintervenciones de 23,5 por ciento. Conclusiones: El implante de válvula de Ahmed en el glaucoma pediátrico refractario es una indicación para la reducción de la presión intraocular(AU)


ABSTRACT Objective: Determine the results of Ahmed glaucoma valve implantation in patients with pediatric refractory glaucoma. Methods: A case-series study was conducted of 15 patients (17 eyes) with pediatric refractory glaucoma attending the pediatric ophthalmology service of Ramón Pando Ferrer Cuban Institute of Ophthalmology from January 2011 to January 2016. These patients underwent Ahmed valve implantation and were followed up for a period of three years. Evaluation was performed of visual acuity, pre- and post-operative intraocular pressure, complete success, qualified success, complications and reinterventions. Results: Mean age of patients was 4.0 years, with a predominance of the male sex (58.8 percent). Mean preoperative intraocular pressure was 37.3 mmHg, significantly decreasing to 19.4 mmHg (p= 0.000) in the postoperative period. Overall survival analysis revealed a cumulative probability of complete success of 94.1 percent at 1.5 months, 70.6 percent at 12 months, 58.8 percent at 18 months and 47.1 percent at 24 and 36 months. Cumulative probability of qualified success was 94.1 percent at 12 months, 82.4 percent at 18 months and 76.5 percent at 24 and 36 months. The rate of complications and reinterventions was 29.4 percent and 23.5 percent, respectively. Conclusions: Indication of Ahmed valve implantation in pediatric refractory glaucoma is aimed at reducing intraocular pressure(AU)

RESUMO

OBJECTIVE: To examine the long-term efficacy, safety and complications of Ahmed glaucoma drainage implant surgery in patients with refractory uveitic glaucoma. METHODS: Retrospective review of consecutive cases of patients with refractory uveitic glaucoma who underwent Ahmed glaucoma drainage implant surgery between 2004-2014. Demographic characteristics of the study population, visual acuity, intraocular pressure (IOP), number of antiglaucoma medications and operative and postoperative complications were recorded. Complete success was defined as IOP≥5 and ≤18mmHg without any medication, as qualified success if IOP≤18mmHg with one or more medications. Patients with less than 12 months of follow-up were excluded. RESULTS: 21 patients (26 eyes) were included. The mean postoperative follow-up was 53.5±31 months. Eight eyes (30%) had at least one previously failed glaucoma surgery. IOP was reduced from a mean of 30.0mmHg to 14.0mmHg at the last follow-up visit (P<.001). The number of IOP-lowering medications was reduced from a median of 2.9 preoperatively to 1.1 at the last follow-up (P<.001). Overall, 7 eyes (27%) were classified as complete success, 13 eyes (50%) were considered as qualified success, and 6 eyes (23%) met the criteria for failure. The most common postoperative complication was hypertensive phase in 12 eyes (46%). Kaplan-Meier life-table analysis showed a cumulative probability of success after Ahmed glaucoma valve implantation of 65% at 84 months. CONCLUSIONS: Ahmed glaucoma drainage implant surgery may be considered a long-term effective and safety surgical option for patients with refractory uveitic glaucoma.

RESUMO

Paciente masculino de 75 años de edad con antecedentes de hipertensión arterial y glaucoma por 30 años. Acudió a la Consulta de Baja Visión del Instituto Cubano de Oftalmología Ramón Pando Ferrer en el año 2016 y refirió disminución progresiva de la visión en el ojo izquierdo. Al fondo de ojo se observó daño glaucomatoso avanzado y degeneración macular seca en evolución. Después de combinar 3 fármacos para ambos ojos a dosis máxima, los valores de la presión intraocular no eran protectores. Se implantó válvula de Ahmed en temporal inferior del ojo izquierdo. A la semana, la agudeza visual se limitaba a movimiento de manos; la presión intraocular era de 6 mmHg y la atalamia grado 4. Se drenó desprendimiento coroideo seroso y se reformó la cámara anterior. Se indicó tratamiento antinflamatorio tópico, sistémico y midriático ciclopléjico. A los 15 días la agudeza visual mejor corregida era de 0,2 y la presión intraocular de 12 mmHg, sin atalamia. Tres meses después se realizó facoemulsificación y se colocó lente intraocular plegable en saco capsular. La agudeza visual mejor corregida era de 0,6 y la presión intraocular de 11 mmHg. La presión intraocular nunca ha superado los 15 mmHg; no se ha detectado progresión del daño glaucomatoso y se ha conservado la agudeza visual(AU)


A male 75-year-old patient with a 30-year history of hypertension and glaucoma presented at the Low Vision Service of Ramón Pando Ferrer Cuban Institute of Ophthalmology in the year 2016 and stated experiencing progressive vision reduction in his left eye. Funduscopy revealed advanced glaucomatous damage and dry macular degeneration in progress. After combining 3 drugs for both eyes at a top dosage, intraocular pressure values were not protective. An Ahmed valve was implanted in the inferior temporal quadrant of the left eye. One week later, visual acuity was limited to hand movement, intraocular pressure was 6 mmHg and athalamia was grade 4. The serous choroidal detachment was drained and the anterior chamber was reformed. Topical antiinflammatory, systemic and mydriatic cycloplegic treatment was indicated. Fifteen days later best corrected visual acuity was 0.2 and intraocular pressure was 12 mmHg, without athalamia. Phacoemulsification was performed three months later and a foldable intraocular lens was placed in the capsular sac. Best corrected visual acuity was 0.6 and intraocular pressure was 11 mmHg. Intraocular pressure has never exceeded 15 mmHg, glaucomatous damage has not been found to progress, and visual acuity has been preserved(AU)

RESUMO

La ciclitis heterocrómica de Fuchs es una uveítis crónica que puede ser asintomática por años o expresar solo la heterocromía antes que aparezca cualquier otro signo. El glaucoma se considera una de las complicaciones más difíciles de tratar, y requiere cirugía en múltiples ocasiones. Los dispositivos de drenaje están siendo cada vez más utilizados como alternativa de tratamiento quirúrgico en estos casos. Asiste a la consulta médica una paciente de 36 años de edad, con antecedentes de uveítis crónica unilateral del ojo izquierdo asociado a catarata y glaucoma descompensado, a pesar del tratamiento médico. Se presenta con 50 VAR de visión y presión intraocular de 32 mmHg. Se realizó cirugía combinada: facoemulsificación e implante de válvula Ahmed modelo S2 con mitomicina C (0,2 mg/mL) durante cinco minutos. Se diagnostica ampolla de filtración encapsulada en la octava semana. Se realiza revisión con aguja y subconjuntival de 1 mg de bevacizumab (avastin) subtenoniano en área de la filtrante. La inyección se repite días alternos hasta completar tres dosis según protocolo institucional. Se logran cifras de presión intraocular de 17 mmHg y agudeza visual mejor corregida de 95 VAR a los 18 meses posoperatorios(AU)


Fuch´s heterochromic cyclitis is chronic uveitis that may be asymptomatic for years or may express heretochromia just before the onset of any other sign. Glaucoma is considered one of the most difficult complications to be treated and requires multiple surgeries. Drainage devices are increasingly used as a surgical treatment option in these cases. Here is the case of a 36 years-old woman with a history of unilateral chronic uveitis in her left eye associated to cataract and decompensate glaucoma despite the medical therapy. She presented with 50 VAR visual acuity and 32 mmHg intraocular pressure. She underwent combined surgery based on phacoemulsification and S2 model Ahmed valve implantation with mitomycin C (0,2 mg/mL) for 5 minutes. The diagnosis was encapsulated filtering bleb at the 8th week of operation. Subconjuctival needle revision with one mg of subtenial bevacizumab (avastin) in the bleb area was performed. Injection was administered every other day till completion of three doses according to the institutional protocol. Eighteen months after the surgery, the intraocular pressure was 17nnHg and the best corrected visual acuity reached 95 VAR best corrected visual acuity(AU)
