Pseudoexfoliación ocular: un signo de alerta temprana de enfermedades sistémicas / Ocular pseudoexfoliation: an early warning signal in systemic diseases

El síndrome pseudoexfoliativo es una enfermedad relacionada con la edad, que afecta a la población mayor de 60 años y tiene una distribución mundial. Se caracteriza por la producción y la acumulación progresiva de un material fibrilar extracelular a nivel de las distintas estructuras del ojo, con repercusiones significativas sobre la salud ocular de los pacientes y, además, conduce a complicaciones quirúrgicas. El material pseudoexfoliativo no solo se encuentra en el globo ocular, sino en distintas partes del organismo, como el corazón, los pulmones, el cerebro y los vasos sanguíneos, por lo que algunos estudios sugieren la relación de este síndrome con ciertas afecciones cardíacas. Se presenta un paciente de 74 años de edad, negro, con antecedentes de hipertensión arterial, que se ingresa por pérdida brusca de la visión de ambos ojos, acompañado de dolor. Al examen oftalmológico, después del tratamiento hipotensor, se constató material pseudoexfolitivo y cristalino subluxado a cámara vítrea. Se diagnosticó glaucoma pseudoexfoliativo, disfunción asintomática del miocardio, hiperlipidemia, ateroma en la aorta abdominal e hipoacusia neurosensorial severa. Existen estudios que sugieren relación del síndrome pseudoexfoliativo con ciertas enfermedades y factores de riegos vasculares con alto impacto en la morbimortalidad a nivel mundial(AU)

Pseudoexfoliation syndrome is an aging-related disease of worldwide distribution affecting people aged over 60 years. It is characterized by progressive production and accumulation of extracellular fibrillar material in the different structures of the eye, with significant impacts on the patients' ocular health. It may also lead to surgical complications. Pseudoexfoliative material is not only found in the eyeball, but also in various parts of the body, such as the heart, the lungs, the brain and blood vessels, this being the reason why some studies suggest a relationship to certain heart conditions. A case is presented of a male black 74-year-old patient with a history of arterial hypertension, admitted due to sudden vision loss in both eyes, accompanied by pain. The ophthalmological examination performed after hypotensive treatment confirmed the presence of pseudoexfoliative material and crystalline subluxated to the vitreous chamber. The diagnosis was pseudoexfoliation glaucoma, asymptomatic myocardial dysfunction, hyperlipidemia, abdominal aorta atheroma and severe neurosensory hypoacusis. Some studies suggest a relationship between pseudoexfoliation syndrome and certain vascular diseases and risk factors with a high impact on worldwide morbidity and mortality(AU)

Excisional goniotomy with Kahook Dual Blade in a patient with glaucoma secondary to Transthyretin Amyloidosis.

PURPOSE: To report for the first time the successful use of the Kahook Dual Blade excisional goniotomy technique in a patient with Transthyretin Amyloidosis. PATIENT AND METHODS: The Kahook Dual Blade is a single use ab interno trabeculectomy device that removes the trabecular meshwork reducing aqueous humor outflow resistance. A patient with Transthyretin Amyloidosis underwent this procedure. RESULTS: Ab interno goniotomy with Kahook Dual Blade was a successful surgical solution to reduce intraocular pressure in a patient with Transthyretin Amyloidosis secondary glaucoma controlling IOP in association with topical hypotensors for at least 6 months. CONCLUSIONS: Ab interno goniotomy with Kahook Dual Blade is a surgical option for this type of glaucoma, that treats the main site of aqueous outflow resistance in this pathology with the advantage of being minimally invasive.

Glaucoma secundario a presión venosa epiescleral elevada en síndrome de Crest / Secondary glaucoma as elevated episcleral venous pressure in Crest syndrome

El glaucoma secundario a presión venosa epiescleral elevada asociada a enfermedad de Crest es una entidad rara, frecuentemente refractaria a la terapia médica y quirúrgica. Debemos ser exhaustivos en la anamnesis, en la exploración y en la solicitud de exámenes de imagen en aras de encontrar la posible causa para lograr un manejo exitoso del paciente con esta enfermedad, tanto desde el punto de vista sistémico como oftalmológico. La cirugía antiglaucomatosa puede ser complicada en estos casos(AU)

Secondary glaucoma as elevated episcleral venous pressure associated to Crest syndrome is a rare condition often refractory to clinical or surgical therapy. Exhaustive anamnesis, exploration and imaging should be conducted to find the possible cause and thus implement successful management of the sufferer, both systemically and ophthalmologically. Glaucoma surgery may be complicated in these cases(AU)

Effect of phacoemulsification on intraocular pressure in patients with primary open angle glaucoma and pseudoexfoliation glaucoma.

AIM: To compare the effect of phacoemulsification on intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG) and pseudoexfoliation glaucoma (PXG). METHODS: A retrospective comparative case series conducted at the Glaucoma Department at the Association to Prevent Blindness in Mexico. The study enrolled consecutive patients having phacoemulsification with intraocular lens (IOL) implantation and a diagnosis of POAG or PXG. Data about IOP values and number of glaucoma medications used was collected at baseline, 1, 3, 6 and 12mo postoperatively. RESULTS: The study enrolled 88 patients (88 eyes). After phacoemulsification, there was a statistically significant reduction in IOP values and glaucoma medications use compared to baseline in both POAG and PXG patients (P<0.001). In the POAG group, a 20% decrease in IOP values was evidenced, and a 56.5% reduction in the number of medications used at the one-year follow-up. The PXG group showed a 20.39%, and a 34.46% decrease in IOP and number of medications used, respectively. A significant difference in the mean ΔIOP (postoperative changes in IOP) was evidenced between groups (P=0.005). The reduction of the postsurgical IOP mean values in both groups, the POAG group showed a greater reduction in IOP values compared to the PXG group. CONCLUSION: In both types of glaucoma, phacoemulsification cataract surgery can result in a significant IOP reduction (20%) over a 12mo follow-up period. The number of medications used is also significantly reduced up to 12mo after surgery, especially in the PXG group.

Trans-scleral diode laser cyclophotocoagulation for refractory glaucoma after high-risk penetrating keratoplasty.

To analyze the intraocular pressure reduction, number of anti-glaucoma medications needed, and post-operative complications of trans-scleral diode laser cyclophotocoagulation (DCPC) in patients with high-risk penetrating keratoplasty (PKP) and secondary refractory glaucoma. Prospective interventional, longitudinal, non-comparative series of cases, including 16 eyes of 15 patient's post-PKP on maximal anti-glaucoma medical therapy with intraocular pressures above 22 mmHg. All patients received 18 shots, 360° peri-limbal (avoiding the long posterior ciliary nerves and arteries at 3 and 9 o'clock positions) of trans-scleral DCPC (2000 mW, time: 2.0 s/shot). There was a 55.5 % reduction (total of 14.0 mmHg) of the mean pre-operative IOP (31.5 mmHg) after the first diode laser application (p = 0.0020). Re-treatment was required in 31.2 % of eyes over a mean period of 10.7 months. In these five eyes, the mean pre-operative IOP was 40.4 mmHg, which decreased to 15.0 mmHg post-therapy, and a mean IOP reduction of 25.4 mmHg (p = 0.0218). There was a 51.0 % reduction in the mean number of medications used after the first, and a 57.1 % reduction after a second laser application. The incidence of failure (IOP ≥ 22 mmHg or need of additional medical therapy) from initial intervention to loss of follow-up was 1.3 % per person-month. DCPC effectively reduces the intraocular pressure and the number of anti-glaucoma medications with few complications in patients after high-risk PKP and secondary glaucoma. Only, one-third of the eyes needed a second intervention to control the intraocular pressure. Post-DCPC complications were limited to phthisis bulbi and endothelial dysfunction, one eye each.

Objetivo: Caracterizar los pacientes atendidos por glaucoma pediátrico, identificar el tratamiento más utilizado para cada subgrupo y conocer los resultados en referencia al control de la presión intraocular. Método: Estudio retrospectivo mediante revisión de historias clínicas de pacientes con glaucoma pediátrico menores de 15 años, pertenecientes al servicio de oftalmopediatría de la Fundación Oftalmológica de Santander Clínica Carlos Ardilla Lülle, atendidos entre enero/2001 y diciembre/2006. Resultados: Del total de casos recolectados, 46 pacientes tenían glaucoma congénito primario, 15 pacientes con glaucoma del desarrollo y 21 pacientes con glaucoma secundario. La técnica quirúrgica más utilizada fue la trabeculotomía combinada con trabeculectomía (TCO+TCE), seguido por la trabeculectomia aumentada con mitomicina (TCE+MMC) y el tratamiento médico tópico con hipotensores oculares. Conclusiones: El glaucoma congénito primario es la causa más frecuente de glaucoma en niños y la técnica combinada de TCE+TCO es el procedimiento de elección con una tasa de éxito del 69.6%.

Background: Glaucoma infrequently affects infants and children, as compared with adults. The prognosis of any glaucoma is better if it is diagnosed early and brought under control. In our experience, primary congenital glaucoma is the most common paediatric glaucoma, and for this condition, combined trabeculotomy+trabeculectomy is the procedure of choice. Objective: To characterize patients seen with paediatric glaucoma, to identify the most often used treatment for each subgroup and the results in reference to the intraocular pressure control. Method: Retrospective clinical record review of paediatric patients with glaucoma under 15 years old, treated in Oftalmopediatrics Service of the Ophthalmologic Foundation of Santander Carlos Ardila Lülle Clinic attended from January/2001 to December/2006. Results: 46 patients had primary congenital glaucoma, 15 had developmental glaucoma, and 21 had secondary glaucoma. The surgical technique most frequently used was trabeculotomy combined with the trabeculectomy (TCO + TCE), followed by trabeculectomy augmented with mitomycin (MMC + TEC) and medical treatment topic with ocular hypotensive. Conclusions: The primary congenital glaucoma is the most frequent cause of glaucoma in children and the combined technique TEC + TCI is the procedure of choice with success rate of 69.9%.
