ARVO preserves its vitality. Occasionally, over the years we lose interest in some conferences, either because we no longer share their aims or because their formats have changed. ARVO continues to be vital and interesting. In my opinion, its interest lies in the fact that the conference's core is constituted by posters, free papers and discussions, which is exactly what other conferences have lost over time and in which free participation is, unfortunately, limited in terms of time and number of participants in order to give their natural place to courses, symposiums, etc.Of all that I managed to see, I would like to single out a specific study that was submitted in poster presentation and which I considered to be very relevant. This study carried out in Marseille assessed the risk of retinal detachment in patients who had undergone cataract surgery. Us retina specialists have seen how the proportion of pseudophakic patients with retinal detachment has increased year after year. This study proves that the risk of retinal detachment increases linearly with the age at which the patient underwent cataract surgery. Overall, the estimated risk is of 1% at 4 year follow-up, but in the case of patients who underwent the procedure between the ages of 40 and 45, the accumulated risk at 4 year follow-up was 5 times greater (5.25%). If we assume that the risk could continue raising exponentially, then a patient who was intervened at the age of 45 and was expected to live until the age of 80, would have to face a total accumulated risk of retinal detachment of over 40%…, terrible. It is very likely that this increase is not actually lineal, and that the curve would end up adopting a plateau over time, although it is also possible that the risk could raise gradually until reaching the age at which the vitreous body detaches physiologically; between the ages of 60 and 70 (Daien V, Lapape A, Heve D, Carriere I, Villain M. Risk factors of retinal detachment following cataract surgery in a national population study between 2009 and 2012). (ARVO: Poster 672-B0238.)The results of this study, which was recently published in the November edition of Ophthalmology,<a class="elsevierStyleCrossRef" href="#bib0015">1</a> should invite us to reflect on the new indications for surgery of the crystalline lens, such as in the case of presbyopia. Although the results of this study are indisputable, the methodology that the author's used is even more so, as the study included over 2,600,000 patients who had underwent cataract surgery. A study including such a volume of patients allows for a comprehensive statistical analysis including a sub-analysis and stratifications to identify risk factors and relevant prognoses.This is a clear example of the use of “big data” applied to medicine. When multinationals of all sorts of activities and sectors support the analysis of “big data” and plan their operating systems to analyse a massive amount of data for the planning of their investments, our health sector falls behind. Most of our hospitals have already implemented the electronic history system, but, unfortunately, the aim was purely administrative and not clinical in nature. Clinical data is stored in unstructured text files and is consequently hard to analyse. Moreover, to make matters worse, these files are included in 17 different electronic systems, one per each autonomous community, which makes it harder to carry out a joint data analysis. Over the years working at a hospital, I have dealt with several hospital managers or directors, all of which were worried about costs, which is a normal and reasonable worry; however, I do not remember any of them showing any interest in the clinical result of the huge expenditure that they continuously and punctually remind us of. Can an economic sector such as that of healthcare dispense with all the clinical information that it generates? Shouldn’t we share the clinical results that we obtain with the resources that we consume with society? Let us imagine for a moment all the improvements that we could implement in our daily practice after adequately analysing all the clinical information that we generate on a daily basis. For example, imagine that we could know the clinical results obtained in the treatment of macular disease with antiangiogenic drugs: we would then be faced with a real and continuous phase IV study.Surely the future of medicine goes hand in hand with research: genetic research will offer patients personalised medical care based on the knowledge of their individual risks. Additionally, the collection and analysis of clinical information, this is to say, the “big data”, which is already used in genetic research,<a class="elsevierStyleCrossRef" href="#bib0020">2</a> will be a cheaper tool that will allow for advancing in the identification of prognostic and risk factors and, therefore, in treatment efficacy. All information needed to reach these conclusions is already available, we are generating it on a daily basis, and we must not let go to waste."

It gives priority to the publication of basic, translational and clinic research including reviews, original articles, short communications, editorials, letters to the editor and clinic practice guides related to Ophthalmology and its subspecialties. A small section of the journal is reserved for the most relevant papers presented at the annual Congress of the Society. All manuscripts considered for publication are reviewed by expert examiner peers (double blind). The journal is published monthly and even though its official language is Spanish all articles are translated into English to increase the dissemination of scientific information. At present, Archivos is the only Spanish language Ophthalmology journal indexed in PubMed/MEDLINE in addition to other prestigious international databases such as Scopus.
