RESUMEN
PURPOSE: To assess the effectiveness and safety of same-site trabeculectomy (TRAB) with mitomycin C (MMC) and Ologen™ (Aeon Astron Europe BV. Leiden, The Netherlands) in patients with a failed non-penetrating deep sclerectomy (NPDS). METHODS: A retrospective study of 24 consecutive eyes (22 patients) undergoing reintervention by same-site TRAB with at least one-year follow-up after failed NPDS. Mean visual acuity (VA), intraocular pressure (IOP) and use of glaucoma medications were compared before and one year after surgery. Early and late postoperative complications were registered. Kaplan-Meier survival analysis was performed according to four levels of success criteria. RESULTS: Overall the mean IOP reduced significantly (24.9 ± 7.1 vs. 14.4 ± 4.5â mmHg; p < 0.001), and the number of glaucoma medications (2.80 ± 1.01 vs. 0.55 ± 0.94; p < 0.001) significantly decreased, one year after surgery. The mean VA remained stable one year after surgery (p = 0.516). Hypotony, defined as IOP ≤ 5â mmHg, in the early postoperative period was observed in 62.5% of eyes, but only in 2 patients (8.33%) in the long term. The mean survival time ranged from 10 months (CI 95% 5-15) to 29 months (CI 95%: 26-32) according to the most stringent and lenient success criteria respectively. CONCLUSION: Same-site TRAB augmented with MMC and Ologen™ may provide an effective, safe and lasting alternative following failed NPDS, especially when sparing of the conjunctiva is highly desirable. Postoperative hypotony is the most common postoperative complication.

OBJECTIVE: To present an update clinical practice guideline that serve as a guide for the detection, evaluation and treatment of adults patients with advanced glaucoma. METHODS: After defining the objectives and scope of the guide, the working group was formed and structured clinical questions were formulated following the PICO (Patient, Intervention, Comparison, Outcomes) format. Once all the existing clinical evidence had been independently evaluated with the AMSTAR 2 (Assessment of Multiple systematic Rewiews) and Cochrane "Risk of bias" tools by at least two reviewers, recommendations were formulated following the Scottish Intercollegiate methodology. Guideline Network (SIGN). RESULTS: Recommendations with their corresponding levels of evidence that may be useful in the diagnosis, monitoring and treatment of adults patients with advanced glaucoma. CONCLUSIONS: Despite the fact that for many of the questions the level of scientific evidence available is not very high, this clinical practice guideline offers an updated review of the different existing aspects related to the evaluation and management of advanced glaucoma.

Aniridia is a congenital bilateral ocular disorder with dominant autosomal inheritance. More than 50% of patients will develop aniridic glaucoma (AG) during their lives. Open angle glaucoma is more common in aniridia, but a closed angle mechanism has been described in relation with anterior rotation of the rudimentary iris, occluding trabecular meshwork. Diagnosis and follow-up of AG is difficult in relation with the presence of keratopathy, nystagmus and foveal hypoplasia. Central corneal thickness usually measures more than 600 microns, which prevents achieving a reliable value of intraocular pressure. Medical treatment of AG is no different from the rest of glaucoma. It is recommended to use preservative free formulations, and combined therapy is often required. Surgical treatment is needed in many cases. There is no consensus on the first line surgery for AG, but in open angle AG, angle surgery is usually first choice, and glaucoma drainage devices are the next preferred surgical technique. In closed angle AG glaucoma drainage devices are usually the first choice, with trabeculectomy as the second preferred surgical technique.

PURPOSE: To describe intracameral toxic effects of cefuroxime at a higher dose than recommended in cataract surgery. METHODS: Retrospective study of 8 eyes of 8 patients who inadvertently received 12.5â¯mg/0.1â¯ml of intracameral cefuroxime due to a dilution error, at the end of the cataract surgery. All patients underwent a strict ophthalmology follow-up for 6 months. RESULTS: All patients presented with a marked anterior segment inflammation with corneal oedema that resolved completely in all cases (between 5 days and 3 months). At 6 months of follow-up a statistically significant difference was found in the corneal endothelial cell density when compared with the fellow eye (Pâ¯=â¯.038), beingâ¯<1000 cells/mm2 in 3 cases. Three patients (37.5%) showed early macular oedema, with subfoveal ellipsoid layer disruption in one case as a permanent sequel. One patient developed an optic neuropathy with associated afferent pupillary defect. CONCLUSIONS: Although 1â¯mg/0.1â¯ml of intracameral cefuroxime has been shown to reduce the incidence of endophthalmitis, its overdose can have potentially toxic eye effects in both anterior and posterior segments.

Objetivo Describir los efectos de la inyección de cefuroxima intracameral a una dosis más alta de la recomendada en cirugía de catarata. Métodos Estudio retrospectivo de 8 ojos de 8 pacientes operados de catarata en un mismo día que recibieron 12,5mg/0,1ml de cefuroxima intracameral de forma inadvertida al finalizar la cirugía, por un error en la dilución. A todos los pacientes se les realizó un seguimiento oftalmológico estrecho durante 6 meses. Resultado Todos los pacientes presentaron una inflamación marcada del segmento anterior con edema corneal que se resolvió en todos los casos (entre 5 días y 3 meses). A los 6 meses de seguimiento se constató una diferencia significativa en el recuento endotelial corneal de dichos ojos al compararlo con el ojo contralateral (p=0,038), siendo<1000cels/mm2 en 3 casos. Tres pacientes (37,5%) presentaron un edema macular precoz, dejando como secuela permanente la disrupción de la capa elipsoidal a nivel subfoveal en uno de los casos. Uno de los pacientes desarrolló una neuropatía óptica con defecto pupilar aferente asociado. Conclusiones Aunque la inyección de cefuroxima en cámara anterior a dosis de 1mg/0,1ml ha demostrado disminuir la incidencia de endoftalmitis, su sobredosificación puede tener efectos oculares potencialmente perjudiciales tanto en el segmento anterior como en el posterior (AU)

RESUMEN
There is a lack of evidence on timing, frequency, and duration of postoperative endocrine, radiologic, and ophthalmologic assessments that should be performed after pituitary surgery (PS). However, it is known that careful optimization of treatment and follow-up strategies as well as a multidisciplinary approach may have a significant impact on long-term outcomes, improving surgical results, minimize complications and facilitate their correct treatment if occurring, and optimize the hormonal, ophthalmological, and radiological reassessment throughout the follow-up. Considering that there are no specific guidelines on the postoperative management of patients with pituitary tumors (PT), we present our protocol for the postoperative management of patients with PT. It has been elaborated by the multidisciplinary team of a Spanish Pituitary Tumor Center of Excellence (PTCE) that includes at least one neurosurgeon, ENT, neuroradiologist, neuro-ophthalmologist, endocrine pathologist and endocrinologist specialized in pituitary diseases. We elaborated this guideline with the aim of sharing our experience with other centers involved in the management of PT thereby facilitating the postoperative management of patients submitted to PS.

PURPOSE: To evaluate acute and chronic changes in optic nerve head (ONH) structures and intraocular pressure (IOP) in patients receiving intravitreal injections (IVIs) of anti-VEGF. METHODS: Twenty-nine eyes receiving IVIs for the first time were studied. IOP, retinal nerve fiber layer (RNFL) thickness, and ONH structures were evaluated by Spectralis optical coherence tomography with enhanced depth imaging technology. Structures were measured before and 5 min after each one of the three monthly injections of a loading dose treatment. In 13 eyes (44.8%) with more than six IVIs, another evaluation pre and immediately postinjection was performed after 1 year. RESULTS: A significant acute and transient IOP increase (all p ≤ 0.001), Bruch's membrane opening (BMO) enlargement (p ≤ 0.001), cup widening (p < 0.05) and deepening (p ≤ 0.001), and prelaminar tissue thinning (p ≤ 0.001) were observed 5 min after each injection. Compared with baseline values, a significant BMO expansion (p = 0.001) and RNFL thinning (p < 0.001) were observed in the third month. In eyes with more than six IVIs, similar immediate postinjection changes, including IOP increase (p = 0.001), prelaminar tissue thinning (p = 0.007), and cup deepening (p = 0.012) were observed at 1 year, while BMO expansion was not significant (p = 0.556). Compared with baseline preinjection values, a significant BMO expansion (p = 0.003), prelaminar tissue thinning (p = 0.011), and cup deepening (p = 0.006) in the inferior region of the ONH occurred. No change in IOP was observed at the end of follow-up. CONCLUSIONS: Repeated IVIs could lead to irreversible changes in ONH structures. Large-scale, prospective studies are required to determine the long-term effects of anti-VEGF treatments in ONH tissues.

OBJETIVO: Evaluar las características y la evolución de los pacientes que requirieron cirugía filtrante de glaucoma (esclerectomía profunda no perforante) para controlar la hipertensión ocular (HTO) secundaria al implante intravítreo de 0,7 mg de dexametasona (Ozurdex(R)). MÉTODOS: Serie de casos observacional retrospectiva de pacientes tratados mediante Ozurdex(R) en un hospital terciario universitario entre mayo 2011 y abril 2016. RESULTADOS: El 1,10% (4/363) de los pacientes tratados con Ozurdex(R) requirieron faco-esclerectomía profunda no perforante (FEPNP) para controlar la HTO secundaria refractaria a tratamiento médico hipotensor. Los 4 casos comenzaron el tratamiento tópico hipotensor o aumentaron su tratamiento hipotensor previo desde el primer implante intravítreo de Ozurdex(R). Todos los casos habían recibido 3 o más inyecciones de Ozurdex(R) antes de que se requiriera la realización de la FEPNP para el control de la PIO. Tras el tratamiento quirúrgico, en todos los casos se alcanzó una PIO óptima sin necesidad de tratamiento tópico adicional. Dos pacientes requirieron retratamiento con nuevas inyecciones de Ozurdex(R) después de la FEPNP, manteniéndose la PIO dentro de los límites normales sin necesidad de tratamiento. CONCLUSIONES: Esta es la primera serie de casos que aporta información acerca de los favorables resultados de la FEPNP como tratamiento de la HTO secundaria a implante intravítreo de Ozurdex(R). Los 4 casos presentan una PIO controlada sin tratamiento tras la cirugía. El retratamiento con Ozurdex(R) en aquellos pacientes que se han sometido a FEPNP es posible, manteniéndose un buen control de la PIO
PURPOSE: To evaluate the characteristics and progression of patients treated with a 0.7 mg dexamethasone intravitreal implant (Ozurdex(R)) and required glaucoma filtering surgery (phaco-non-penetrating deep sclerectomy) to control ocular hypertension (OHT). METHODS: A retrospective observational study including patients treated with Ozurdex(R) in a tertiary-care university hospital from May 2011 to April 2016. RESULTS: In five years of follow-up, 1.10% (4/363) of patients treated with 0.7 mg dexamethasone intravitreal implant required phaco-non-penetrating deep sclerectomy (PNPDS) to control OHT refractory to topical treatment. All four patients started or increased previous antihypertensive topical treatment since the first dexamethasone intravitreal implant. Three or more dexamethasone intravitreal implants were injected in the four cases before intraocular pressure (IOP) became uncontrolled and PNPDS was performed. All four patients have a successfully controlled IOP without treatment after PNPDS. Two patients required additional treatment with dexamethasone intravitreal implants after PNPDS, maintaining IOP under control without treatment. CONCLUSIONS: To the best of our knowledge, this is the first study describing the successful results of PNPDS in OHT secondary to dexamethasone intravitreal implant. All four patients have achieved controlled IOP without treatment. Re-treatment with dexamethasone intravitreal implant in those patients who underwent PNPDS is also possible, and IOP remains controlled
