ABSTRACT
INTRODUCTION: Reperfusion therapies represent promising treatments for patients with Central Retinal Artery Occlusion (CRAO), but access is limited due to low incidence and lack of protocols. We aimed to describe the benefit of implementing a Retinal Stroke-Code protocol regarding access to reperfusion, visual acuity and aetiological assessment. PATIENTS AND METHODS: Prospective cohort study performed at a Comprehensive Stroke Centre. Criteria for activation were sudden monocular, painless vision loss within 6 h from onset. Eligible patients received IAT when immediately available and IVT otherwise. All patients were followed by ophthalmologists to assess best-corrected visual acuity (BCVA) and visual complications, and by neurologists for aetiological workup. Visual amelioration was defined as improvement of at least one Early Treatment Diabetic Retinopathy Study (ETDRS) letter from baseline to 1 week. RESULTS: Of 49 patients with CRAO, 15 (30.6%) received reperfusion therapies (12 IVT, 3 IAT). Presentation beyond 6 h was the main contraindication. Patients receiving reperfusion therapies had better rates of visual improvement (33.3% vs 5.9%, p = 0.022). There were no complications related to reperfusion therapies. Rates of neovascular glaucoma were non-significantly lower in patients receiving reperfusion therapies (13.3% vs 20.6%, p = 0.701). Similar rates of atherosclerotic, cardioembolic and undetermined aetiologies were observed, leading to 10 new diagnosed atrial fibrillation and five carotid revascularizations. CONCLUSION: A comprehensive acute management of CRAO is feasible despite low incidence. In our study, reperfusion therapies were safe and associated with higher rates of visual recovery. A similar etiological workup than ischemic stroke led to of high proportion of underlying aetiologies.

AIM: To assess the efficacy and safety of non-penetrating deep sclerectomy (NPDS) with uveoscleral implant plus subconjunctival and intrascleral collagen matrix overcoming the superficial scleral flap lips (modified deep sclerectomy technique, DS) and minimal use of mitomycin C in glaucoma surgery. METHODS: A retrospective review of 47 consecutive glaucoma patients who underwent NPDS with DS between January 2017 and May 2018. Best-corrected visual acuity, intraocular pressure (IOP), post-operative need for glaucoma medications, visual field mean deviation (MD), re-interventions, needling revisions and laser goniopuncture were noted. Absolute success was defined as IOP≤18 mm Hg without topical medication. Relative success was defined as the same criteria but with the addition of any antihypertensive medication. IOP over 18 mm Hg on two consecutive follow-up visits was considered as a failure. RESULTS: Fifty-two eyes of 47 patients were evaluated. Mean preoperative IOP was 25.37±6.47 mm Hg, and decreased to 15.04±4.73 at 12mo and 12.21±4.1 at 24mo (all P<0.0001). Requirement for topical medications dropped from a mean of 3.06±0.25 per patient to 0.51±0.99 and 1.11±1.23 respectively after 12 and 24mo (all P<0.0001). No medications were required in 45.5% of patients after 24mo. Relative and absolute success rate at 24mo were 85.5%±5% and 48.5%±7.4%, respectively. CONCLUSION: DS is a safe and effective non-penetrating glaucoma surgery variation. It aims to retain the patency of all pathways created for aqueous humor drainage: the intrascleral bleb, the supraciliary space and the open communication between intrascleral and subconjunctival compartments.
ABSTRACT
BACKGROUND: The maxillary artery (MA) is one of the terminal branches of the external carotid artery (ECA) and through its branches, it is responsible for vascularizing several organs and muscles of the head and neck, including their surrounding soft tissues, the oral and sinonasal cavities, dura mater, and various cranial nerves. The aim of this study was to conduct a systematic review and meta-analysis of maxillary artery anatomy according to the Anatomical Quality Assurance (AQUA) checklist. METHODS: We conducted a systematic search through PubMed, EMBASE, Scopus, ScienceDirect, Web of Science, SciELO, Springerlink, WILEY and BIREME databases. We applied the Anatomical Quality Assurance (AQUA) checklist for analysis the methodological quality of the articles. RESULTS: From a total of 11,759 articles found in the first search, and after applying the inclusion/exclusion criteria, in addition to eliminating duplicate articles, a final number of 24 articles were identified. The information on the maxillary artery was analyzed from each study regarding its course in relation to the lateral pterygoid muscle, the intra- and extraluminal diameters of the maxillary artery and its branches, and the types of branching of the maxillary artery in the pterygopalatine fossa. CONCLUSION: From this study, it was possible to conclude the importance of anatomical knowledge of the maxillary artery, for its application in the clinical study of the head and neck, as well as the need to apply the AQUA checklist in the development of systematic anatomical reviews to ensure accurate reliability and a better assessment of the effect of anatomical publications.
