[Limitations of outpatient vitreoretinal surgery at the Toulouse University hospital between 2016 and 2020: Causes for traditional hospitalization]. / Les limites de l'ambulatoire en chirurgie vitréo-rétinienne au CHU de Toulouse entre 2016 et 2020 : identification des causes d'hospitalisation traditionnelle.

INTRODUCTION: Currently, the majority of patients undergoing vitreoretinal surgery (VRS) are managed on an outpatient basis; this has been made possible by major surgical and anesthetic advances over the past decades. Nevertheless, the conversion to "all outpatient" surgery still poses some problems that are interesting to identify, and traditional hospitalization remains the solution in many situations. METHODS: All patients undergoing VRS at the Toulouse University Hospital between 2016 and 2020 were included retrospectively. For each patient, we analyzed the entire medical, anesthesia and demographic records. We performed a simple descriptive analysis of all parameters studied, followed by a bi-variate analysis between the "Outpatient/Hospitalization" parameter and all other parameters. RESULTS: Three thousand patients were included over the study period; 79.4% of patients were managed on an outpatient basis compared to 20.6% by traditional hospitalization. Failure of ambulatory care was the cause of 41.9% of the traditional hospitalizations, with the absence of an accompanying person on the evening of the surgery being the main reason (47.8%). DISCUSSION: Social isolation is found to be one of the main causes of failure of ambulatory care; improvements might be made at this level, in order to reduce the burden on the inpatient hospital system.

[Assessment of astigmatism associated with the iris-fixated ARTISAN aphakia implant: Anterior fixation versus posterior fixation, study of postoperative follow-up at one year]. / Évaluation de l'astigmatisme associé à l'implant ARTISAN Aphakia fixé à l'iris en face antérieure versus face postérieure : étude du suivi postopératoire sur un an.

PURPOSE: The goal of our retrospective, single-center study of a case series was to compare the total, corneal, and internal astigmatism, and the visual acuity at one year after combined or stand-alone surgery consisting of iris fixation of an iris-claw intraocular lens (ARTISAN aphakia) in aphakic patients, according to whether the lens was fixated to the anterior (n=21) or posterior (n=51) surface of the iris. RESULTS: We did not find a significant difference between these two types of fixation for any of the studied variables. The surgically induced astigmatism was 1.67 D at 176° in group A versus 1.19 D at 11° in group P. CONCLUSION: Although this surgery creates additional corneal astigmatism, it has not been proven that it differs depending on the type of fixation of the iris-claw. If we adhere to the notion that the posterior fixated iris-claw decreases the risk of endothelial decompensation in case the implant becomes disenclavated, then reverse iris fixation of the iris-claw makes sense.

[Evaluation of the nurse triage at the ophtalmology emergency department of Pierre-Paul-Riquet Hospital]. / Évaluation du questionnaire de tri infirmier aux urgences ophtalmologiques de l'hôpital Pierre-Paul-Riquet au CHU de Toulouse.

INTRODUCTION: The steady increase in the number of visits to the various emergency services combined with the decrease in medical demographics, make it necessary to optimize triage of patients to improve their care. The purpose of this study was to evaluate the pertinence of our triage questionnaire in the classification of ophthalmologic emergencies by severity. METHODS: We used a monocentric cross-sectional study. From September 5 through September 25 2017, 858 patients who had all been seen in the ophthalmology emergency department of Pierre Paul Riquet Hospital of Toulouse university medical center and had responded to the triage nurse questionnaire were included. According to the symptoms presented or not by the patient, a color code was attributed (GREEN, ORANGE or RED) in order of increasing level of emergency. For each patient, we compared the severity of the final diagnosis by Base Score with the level of emergency established by our questionnaire. RESULTS: There were 118 "GREEN" patients, 606 "ORANGE" patients and 134 "RED." We were able to analyze 822 patients. 21.65% of patients were correctly classified, 73.36% were overestimated (of which 87.06% by one level and 12.94% by two levels of severity), and 4.99% were underestimated (of which 90.24% by one level and 9.76% by two levels). CONCLUSION: Our current triage questionnaire is not sufficiently discriminating for effective triage of ophthalmologic emergencies. It often overestimates minor emergencies, causing a delay in treating other emergencies. We propose a new questionnaire modified according to the results obtained during our study.
