Evaluación de signos tomográficos no exudativos en casos de degeneración macular asociada a la edad de tipo exudativo / Evaluation of non-exudative tomographic signs in cases of exudative age-related macular degeneration

Objetivo Analizar la prevalencia de signos tomográficos no exudativos (signo de cebolla, seudoedema, tubulación de la retina externa, seudoquistes, hendiduras subretinianas y atrofia macular) en pacientes con degeneración macular asociada a la edad neovascular. Material y métodos Un total de 174 ojos de pacientes con degeneración macular asociada a la edad neovascular que no habían recibido tratamiento previo fueron incluidos en el estudio. Se valoró la agudeza visual, la actividad de la neovascularización y la aparición o no de los distintos signos objeto de estudio en los tiempos 0 (visita inicial), 4 meses, un año, año y medio y a los 2 y 3 años de seguimiento. Se evaluaron también: la edad, el sexo, el ojo afecto y el tipo de neovascularización (1, 2, 3, polipoidea o mixta). Los análisis se han realizado mediante el software estadístico R (versión 3.3.2) y el paquete glmmADMB (versión 0.8.3.3). Resultados La presencia de seudoquistes y tubulación de la retina externa va en aumento a lo largo del seguimiento. El signo de cebolla comienza con una frecuencia ascendente hasta los 12 meses, posteriormente desciende a los 18 meses y vuelve a incrementarse a los 24 meses. En cuanto al seudoedema, mantiene un incremento hasta los 18 meses para finalmente descender. Las hendiduras subretinianas son el signo más raro, presentándose en el 1,1% en la primera visita. Finalmente, la atrofia macular, presente en el 12,6% de los ojos inicialmente, se encuentra en el 25% a los 2 años. Conclusión Los seudoquistes, la tubulación de la retina externa y la atrofia macular fueron los signos más prevalentes, mientras que las hendiduras subretinianas fueron los más infrecuentes (AU)

Objective To analyze the prevalence of non-exudative tomographic signs (onion sign, pseudoswelling, external retinal tubulation, pseudocysts, subretinal clefts and macular atrophy) in patients with neovascular age-related macular degeneration. Material and methods A total of 174 eyes of patients with neovascular age-related macular degeneration who had not received previous treatment were included in the study. Visual acuity, neovascularization activity, and the appearance or not of the different signs under study were assessed at times 0 (initial visit), 4 months, one year, year and a half, and at 2 and 3 years of follow-up. The following were also evaluated: age, sex, affected eye and type of neovascularization (1, 2, 3, polypoid or mixed). The analysis were performed using the statistical software R (version 3.3.2) and the glmmADMB package (version 0.8.3.3). Results The presence of pseudocysts and external retinal tubulation increases throughout the follow-up. The onion sign begins with an ascending frequency up to 12 months, then decreases at 18 months and increases again at 24 months. Regarding pseudowelling, it maintains an increase until 18 months to finally decrease. Subretinal clefts is the rarest sign, presenting in 1.1% on the first visit. Finally, macular atrophy, present in 12.6% of the eyes initially, is found in 25% after 2 years. Conclusion Pseudocysts, external retinal tubulation and macular atrophy were the most prevalent signs, while subretinal clefts were the most infrequent (AU)

Ocular complications secondary to diode laser-assisted eyebrow epilation.

We describe two cases of ocular complications secondary to Diode laser assisted eyebrow epilation. Both included patients were women who underwent an eyebrow epilation procedure with Diode laser. A few hours after the procedure they started complaining with photophobia and blurred vision. They were diagnosed with anterior acute uveitis and treated with topical steroids and mydriatics. During the follow-up the presence of sequelae derived from the laser procedure (mydriasis and corectopia in both patients, cataract in the second one) was confirmed. Laser hair removal of the eyebrows can induce irreversible eye damage. Complete and reliable information regarding the potential side effects of this procedure and proper use of appropriate safety devices is mandatory. We point out the importance of the potential ocular side effects associated with these cosmetic devices.

Recommendations for eye care during the alarm state by the coronavirus disease pandemic COVID-19. / Recomendaciones para la atención oftalmológica durante el estado de alarma por la pandemia de enfermedad por coronavirus COVID-19.

OBJECTIVE: Minimize exposure to the SARS-CoV-2, reduce the chances of cross-transmission between patients and healthcare personnel, and prevent the development of postoperative complications from the management of patients with eye diseases during the 2019 coronavirus disease pandemic (COVID-19). METHODS: COVID-19 literature review and consensus establishment between different Spanish ophthalmology societies in order to provide guidelines and recommendations of maximum resources primarily conditioned by the state of alert, confinement and social distancing that occurs in Spain since March 16, 2020. RESULTS: The recommendations will promote the adoption of action and protection measures for eye care in outpatient clinics, surgical areas and hospitalization, for unconfirmed (asymptomatic and symptomatic) and confirmed COVID-19 patients. Measures must be adapted to the circumstances and availability of personal protective equipment in each of the centers and Autonomous Communities, which will be updated according to the pandemic phases and the measures adopted by the Spanish Government. CONCLUSIONS: During the COVID-19 pandemic, attention to the potential health risks to the population caused by coronavirus should prevail over the possible progression of the common eye diseases. Ophthalmologists and other eye care professionals must assume a possible progression of these diseases due to the impossibility of adequate patient follow-up.

Neurorretinitis estrellada idiopática de Leber: conflictos diagnósticos y terapéuticos / Leber's idiopathic stellate neuroretinitis: diagnostic and therapeutic conflicts

Presentamos 3 pacientes con clínica de disminución de agudeza visual, papilitis y desarrollo de estrella macular al cabo de unas semanas. En todos ellos, las pruebas complementarias arrojaron resultados irrelevantes. Dado este contexto, fueron diagnosticados de neurorretinitis estrellada idiopática de Leber (NEIL) y se pautó tratamiento con corticoides, así como antibióticos en 2de ellos. Evolucionaron favorablemente, aunque con signos de atrofia papilar en los ojos afectos. El diagnóstico de la neurorretinitis estrellada idiopática de Leber puede resultar complejo, dado el amplio espectro de enfermedades que descartar. A esto se suma un período de tiempo en el que puede no haber aparecido la estrella macular, motivo que no debe hacer excluir su diagnóstico. El uso de antibióticos o corticoides como medida terapéutica es controvertido dado su buen curso clínico, aunque parece razonable en casos severos. Otro punto controvertido es el uso rutinario de pruebas complementarias, principalmente aquellas que pueden resultar agresivas o caras, que deben ser utilizadas de forma racional

Three cases of patients with decreased visual acuity and papillitis at onset with subsequent macular star development after a few weeks are presented. Complementary tests were unremarkable in all included patients. Based on this clinical context, they were diagnosed with Leber's idiopathic stellate neuroretinitis, were treated with corticosteroids, as well as with antibiotics in 2 cases. All patients showed favourable outcomes, although signs of papillary atrophy were observed in the affected eyes. Leber's idiopathic stellate neuroretinitis diagnosis can be challenging due to the wide spectrum of conditions that have to be ruled out. In addition, macular star may appear later on, which should not exclude its diagnosis. Use of antibiotics and/or corticosteroids is controversial considering its benign nature, but should be considered in selected severe cases. Moreover, the routine use of complementary tests should be carefully evaluated, mainly those that can be aggressive and/or expensive, which should be rationally used

Coriorretinitis placoide sifilítica. Caso clínico / Syphilitic placoid chorioretinitis. A case-report

CASO CLÍNICO: Presentamos el caso de una mujer de 45 años sin antecedentes de interés y con una pérdida súbita de visión en su ojo izquierdo secundaria a una uveítis posterior bilateral. Tras despistaje, se diagnosticó de coriorretinitis placoide posterior aguda sifilítica, y recibió tratamiento con penicilina intravenosa. Discusión: Existen múltiples manifestaciones oculares de la sífilis que pueden simular cuadros y etiologías muy diversas. El tratamiento anti-treponémico normalmente produce una rápida y positiva respuesta en pacientes afectos. El diagnóstico precoz y certero de estos pacientes es por tanto crucial aunque, en ocasiones, los daños anatómicos y funcionales son irreversibles

CLINICAL CASE: We report the case of a 45-year-old woman, with unremarkable past medical history, who presented with acute visual loss in her left eye due to bilateral posterior uveitis. After the screening, she was diagnosed with acute syphilitic placoid chorioretinitis and was treated with intravenous penicillin. DISCUSSION: Clinical manifestations of ocular syphilis are extremely heterogeneous and may mimic several aetiologies. Anti-treponema treatment usually induces a quick and positive response in affected patients. Prompt and proper diagnosis of these patients is crucial, although anatomical and functional damage may persist

Study of association of CTLA4 gene variants to non-anterior uveitis.

This study was undertaken to investigate the possible genetic association of functional CTLA4 polymorphisms with susceptibility to non-anterior uveitis. Four hundred and seventeen patients with endogenous non-anterior uveitis and 1517 healthy controls of Spanish Caucasian origin were genotyped for the CTLA4 polymorphisms rs733618, rs5742909 and rs231775, using predesigned TaqMan(©) allele discrimination assays. PLINK software was used for the statistical analyses. No significant associations between the CTLA4 polymorphisms and susceptibility to global non-anterior uveitis were found. It was also the case when the potential association of these genetic variants with the anatomical localization of the disease, such as intermediate, posterior or panuveitis, was assessed. Our results do not support a relevant role of these CTLA4 polymorphisms in the non-anterior uveitis genetic predisposition.

Queratouveítis herpética bilateral en paciente inmunocompetente / Bilateral herpetic keratouveitis in an immunocompetent patient

CASO CLÍNICO: Se presenta el caso de un varón inmunocompetente que acude a nuestro servicio con escleritis adyacente a limbo y queratitis intersticial en ojo izquierdo. A los pocos días se observa nueva úlcera de aspecto dendritiforme en ojo derecho y empeoramiento bilateral progresivo hasta presentar uveítis granulomatosa en ambos ojos. En el estudio etiológico destacan títulos positivos de IgM para virus herpes simple en suero. DISCUSIÓN: Ante un cuadro de queratouveítis bilateral de tórpida evolución con tratamiento convencional, es necesario descartar el origen herpético debido a las diferentes presentaciones de este virus

CASE REPORT: We report the case of an immunocompetent male who presented with a limbal-adjacent scleritis and interstitial keratitis in the left eye. A few days later a new dendritiform ulcer in his right eye and bilateral progressive worsening with granulomatous uveitis in both eyes were observed. A thorough review of systems revealed positive serum IgM titles for herpes simplex virus. DISCUSSION: In the context of a bilateral keratouveitis refractory to conventional treatment it is mandatory to rule out the herpetic origin based on the different forms of clinical presentation of this virus

Tratamiento de las uveítis tuberculosas presuntas del segmento posterior: confirmación diagnóstica y resultados a largo plazo / Treatment of presumed tuberculous uveitis affecting the posterior segment: diagnostic confirmation and long term outcomes

Objetivo: Describir el grado de coincidencia con el diagnóstico de presunción así como los resultados clínicos obtenidos a largo plazo tras el tratamiento antituberculoso (ATT) en un grupo de pacientes con uveítis tuberculosas presuntas (UTBP) que afectaban al segmento posterior. Métodos: Estudio retrospectivo. Serie de pacientes. Resultados: Se incluyeron a 17 pacientes con distintos tipos de uveítis del segmento posterior, crónicas, refractarias o de reciente diagnóstico y diversas manifestaciones clínicas, en los que, tras establecerse el diagnóstico de UTBP, se completó ATT. La media de seguimiento fue de 34 meses (rango 2-60). Hubo control de la inflamación en 14/17 pacientes (82,3%) durante el periodo de tratamiento y solo 4/17 pacientes (23,5%) experimentaron una recidiva de su enfermedad a lo largo del periodo de seguimiento tras ATT. Todos los pacientes que sufrieron recidivas (4/4), pero ninguno de los que no las sufrieron (0/13) requirieron terapia inmunosupresora de algún tipo tras ATT. La respuesta al ATT sirvió para confirmar el diagnóstico de UTBP en 14/17 pacientes (82,3%). Conclusiones: En pacientes con sospecha de UTBP que afecta al segmento posterior, el ATT puede ser una eficaz medida para confirmar el diagnóstico y resolver el cuadro inflamatorio. En este contexto, el ATT puede ofrecer otras potenciales ventajas como prevenir futuras reactivaciones de tuberculosis secundarias a tratamiento inmunosupresor o disminuir la frecuencia o la severidad de recaídas en algunos pacientes. La confirmación de estas y otras ventajas requiere trabajos prospectivos, aleatorizados con mayor número de pacientes (AU)

Objective: To determine the level of agreement with the presumed diagnosis and long term clinical outcomes after antituberculous therapy (ATT) in a group of patients with presumed tuberculous uveitis (PTU) affecting the posterior segment. Methods: Retrospective case series. Results: A total of 17 patients with chronic refractory or newly diagnosed uveitis affecting the posterior segment were included. All included patients were diagnosed with PTU and received ATT. Median follow-up after ATT was 34 months (range 2-60). Complete control of inflammation was observed in 14/17 patients (82.3%) during the treatment period, and only 4/17 patients (23.5%) had a uveitis relapse over the entire follow-up period after ATT. All patients who had uveitis relapses (4/4), but none from the remaining group (0/13), required immunosuppressive therapy of some kind after ATT. The response to ATT was able to confirm diagnosis of PTU in 14/17 (82.3%) included patients. Conclusion: When a clinical suspicion of PTU affecting the posterior segment exists, ATT may be highly effective for both confirming the diagnosis and resolving the inflammatory process. Thus, ATT may offer additional advantages, such as preventing latent-tuberculosis reactivations due to immunosuppressive therapy, and decreasing the number and/or severity of uveitis relapses in some patients. Prospective, randomized studies including a larger number of patients are required to support these and other potential advantages of ATT in such patients (AU)

Adalimumab specifically induces CD3(+) CD4(+) CD25(high) Foxp3(+) CD127(-) T-regulatory cells and decreases vascular endothelial growth factor plasma levels in refractory immuno-mediated uveitis: a non-randomized pilot intervention study.

AIM: To explore immunoregulatory and anti-inflammatory pathways specifically targeted by a subcutaneous anti-TNFαdrug-adalimumab-which might be relevant for controlling refractory uveitis. DESIGN: Non-randomized pilot intervention study on the effects of adalimumab on Treg populations and plasma VEGF levels in refractory uveitis patients. Inflammatory and immunological parameters were measured in 12 patients before therapy, and 1 and 6 months after therapy, and analyzed in the context of ophthalmological outcomes. The results were compared with those obtained in 10 systemic prednisone-treated uveitis patients. RESULTS: After 1 month of treatment, all patients responded, with 67% of adalimumab group and 80% of the corticosteroid group achieving inactivity (P=0.5). Unlike steroid-treated patients, a significant increase in T-regulatory CD4(+) CD25(high) Foxp3(+) CD127(-) cells was observed in adalimumab patients after 1 month of treatment, and maintained after 6 months (P=0.003). A significant adalimumab-specific drop in plasma VEGF was observed after 1 and 6 months of treatment (P=0.019). In every single patient, Tregs but not VEGF correlated with disease activity. CONCLUSIONS: In refractory uveitis patients treated with adalimumab, clinical efficacy may be mediated through upregulation of Tregs in addition to modulation of VEGF-mediated inflammatory pathways. These biological properties, which were not observed in patients treated with corticosteroids, may reflect the specificity of TNF-αtargeting.

Ketorolac therapy for the prevention of acute pseudophakic cystoid macular edema: a systematic review.

To assess the effectiveness of ketorolac vs control for prevention of acute pseudophakic cystoid macular edema (CME). The following databases were searched: Medline (1950-June 11, 2011), The Cochrane Library (Issue 2, 2011), and the TRIP Database (up to 11 June 2011), using no language or other limits. Randomized controlled clinical trials (RCTs) were included that consisted of patients with acute pseudophakic cystoid macular edema, those comparing ketorolac with control, and those having at least a minimum follow-up of 28 days. In the four RCTs evaluating ketorolac vs control, treatment with ketorolac significantly reduced the risk of CME development at the end of treatment (≈ 4 weeks) compared to control (P=0.008; 95% confidence interval (0.03-0.58)). When analyzed individually, each individual study was statistically nonsignificant in its findings with the exception of one study. When the pooled relative risk was calculated, the large sample size of this systematic review led to overall statistical significance, which is attributable to the review's large sample size and not to the individual studies themselves. In this systematic review of four RCTs, two of which compared ketorolac with no treatment and two of which evaluated ketorolac vs placebo drops, treatment with ketorolac significantly reduced the risk of developing CME at the end of ≈ 4 weeks of treatment compared with controls. These results, however, should be interpreted with caution considering the paucity of large randomized clinical trials in the literature.

[Creutzfeldt - Jakob presenting with isolated visual symptoms: the Heidenhain variant]. / Creutzfeldt - Jakob con debut oftalmológico: la variante Heidenhain.

CLINICAL CASE: We report the case of a 67 year old female complaining of decreased vision and diagnosed with the Heidenhain variant of sporadic Creutzfeldt-Jakob disease. Her past medical history was unremarkable. She died less than three months after the onset. DISCUSSION: The Heidenhain variant of sporadic Creutfeld-Jakob disease should be suspected in patients suffering from early visual disturbances, unremarkable ophthalmic examination, and subsequent rapid decline of their cognitive function. A complete neurological exam including electroencephalogram recordings and magnetic resonance is mandatory. These patients share a common genotype (PRNP codon 129 MM) associated with a clinically typical disease course.
