Abstract: On the occasion of the dictation of the Judgment of the Court of Justice of the European Union in the matter called the "legislative vacation", some of the questions that it has raised in the doctrine are examined; notably, the theory of the reserve of Administration and administrative discretion. Finally, the author proposes that this ruling responds to a progressive constitutional mutation that has been taking place in the internal legal systems of the Member States as a result, in this case, of the transfer of competences to the European Union, which entails modifying -in the matters that have been intervened by said supranational instance- the role that the traditional conception assigns to the legislative power.

Resumen: Con ocasión de la dictación de la Sentencia del Tribunal de Justicia de la Unión Europea en el asunto denominado las “vacaciones legislativas”, se examinan algunas de las cuestiones que la misma ha suscitado en la doctrina; señaladamente, la teoría de la reserva de Administración y la discrecionalidad administrativa. Por último, el autor plantea que aquella sentencia responde a una progresiva mutación constitucional que se ha ido produciendo en los ordenamientos jurídicos internos de los Estados miembros a consecuencia, en este caso, de la transferencia de competencias a la Unión Europea, lo cual comporta modificar -en las materias que han sido intervenidas por dicha instancia supranacional- el papel que la concepción tradicional le asigna al poder legislativo.

Background: Ocular Surface Disease Index (OSDI) is the most commonly used questionnaire worldwide to detect dry eye disease. Although it is massively used in clinical practice in Chile, its use has not been validated yet in the country. Aim: To develop a cultural adaptation and to validate the OSDI questionnaire for the Chilean population. Material and Methods: For cultural adaptation, a translation, retro-translation and an expert panel review was carried out. The resulting questionnaire was applied to a pilot group of twelve participants and their comments were considered for the final questionnaire version. The final questionnaire was applied to a non-random sample of 200 patients aged 53 ± 17 years (75% women). Internal consistency and construct validity were evaluated by Cronbach’s alpha and exploratory factor analysis respectively. Results: According to the OSDI score, 81% of respondents had dry eye (55% severe). Reliability was 0.91 and factor analysis resulted in three factors explaining 75.4% of the total variance. Conclusions: The OSDI questionnaire version obtained in this study demonstrated excellent internal consistency values and adequate construct validity making it applicable to clinical practice and dry eye research.

Abstract: On the occasion of the presentation of the statement that administrative law should operate as a science that aims to effectively manage social processes, the author analyzes three specific topics: 1) the administrative procedure and the plurality of values and interests; 2) the challenges that scientific-technological progress imposes on the Law; and, 3) the construction of the guarantor and regulatory State.

Resumen: Con ocasión de la exposición del planteamiento que afirma que el Derecho administrativo debe operar como ciencia que aspira a dirigir con eficacia los procesos sociales, el autor analiza tres temas específicos: 1) el procedimiento administrativo y la pluralidad de valores e intereses; 2) los retos que los progresos científico-tecnológicos le imponen al Derecho; y, 3) la construcción del Estado garante y regulador.

RESUMO Objetivo: Descrever um algoritmo reprodutível para o tratamento cirúrgico das complicações da bolha de início tardio (>2 meses) após trabeculectomia com mitomicina-C. Métodos: Revisão retrospectiva de olhos que foram submetidos a um algoritmo reprodutível para o tratamento cirúrgico das complicações da bolha de início tardio por um único cirurgião, de julho de 2006 a abril de 2014. Os critérios de exclusão foram revisão de bolha com menos de 3 meses de seguimento ou revisão de bolha combinado com outro procedimento antiglaucomatoso no momento da cirurgia. O sucesso foi avaliado pelo método de sobrevida de Kaplan-Meier e definidos como ter atingido todos os seguintes critérios: indicação de cirurgia primária resolvido, nenhuma cirurgia adicional necessária para diminuir a pressão intraocular (IOP), IOP ≥6 mmHg e ≤18 mmHg. Resultados: Vinte e três olhos de 20 pacientes foram incluídos. Indicações para revisão bolha foram maculopatia hipotônica (47,8%), extravasamento da bolha (30,4%) e bolha elevada (21,7%). A taxa de sucesso do resultado primário global calculada pelo método de sobrevivência de Kaplan-Meier foi de 65,2% aos 48 meses. Quando a IOP foi diminuída para ≤15mmHg, a taxa de sobrevivência bolha foi de 47,8% em 48 meses. Na visita pós-operatória mais recente, 95,7% dos olhos apresentavam PIO ≤15mmHg e 56,5% estavam sob tratamento com uma média de um medicamento por olho. Um olho (4,3%) necessitou de uma segunda revisão da bolha para hipotonia persistente e dois olhos necessitaram cirurgia de antiglaucomatosa para reduzir a IOP durante o seguimento. Conclusões: Um algoritmo de abordagem para o tratamento cirúrgico das complicações tardias da bolha com uma taxa de sucesso semelhante aos relatados na literatura especializada é proposto. Ensaios clínicos randomizados são necessários para confirmar a melhor abordagem cirúrgica.

ABSTRACT Purpose: The aim of this study was to introduce a reproducible algorithm for the surgical management of late-onset (>2 months) bleb complications after trabeculectomy with mitomycin C. Methods: We performed a retrospective review of eyes treated using a reproducible algorithm approach by a single surgeon for the surgical management of late-onset bleb complications from July 2006 to April 2014. Exclusion criteria were bleb revision with less than 3 months of follow-up or bleb revision combined with other glaucoma procedures at the time of surgery. Success was evaluated using the Kaplan-Meier survival method and defined as achieving all of the following criteria: primary surgery indication resolved, no additional surgery required for decreasing the intraocular pressure (IOP), and IOP of ≥6 mmHg and ≤18 mmHg. Results: Twenty-three eyes from 20 patients were evaluated. Indications for bleb revision were hypotonic maculopathy (47.8%), bleb leak (30.4%), and dysesthetic bleb (21.7%). The overall primary outcome success rate calculated using the Kaplan-Meier survival method was 65.2% at 48 months. When the IOP target was changed to ≤15 mmHg, the bleb survival rate was 47.8% at 48 months. At the most recent postoperative visit, 95.7% of eyes had an IOP of ≤15 mmHg and 56.5% were being treated with an average of one medication per eye. One eye (4.3%) required a second bleb revision for persistent hypotony and two eyes required glaucoma surgery to reduce IOP during follow-up. Conclusions: An algorithm approach for the surgical management of late-onset bleb complications with a success rate similar to those reported in specialized literature is proposed. Randomized trials are needed to confirm the best surgical approach.
