Purpose: To explore whether a patient's prior knowledge of the symptoms associated with rhegmatogenous retinal detachment (RRD) relates to the visual outcome after treatment. Methods: We performed a prospective survey study on 126 patients receiving treatment for primary RRD between March and July 2021. Results: Thirty‐seven per cent (n = 47) of patients responded that they were aware of the RRD symptoms prior to the detachment. A history of RRD in the fellow eye or knowledge of family members treated for RRD was frequently reported as a reason for the patient's awareness of RRD symptoms. Patients aware of RRD symptoms presented significantly more often with an attached macula (χ2, p = 0.002) and a better visual outcome following surgery (Mann–Whitney U, p = 0.028) compared to patients who were not aware of RRD‐related symptoms. Among 76 patients with a myopic refractive error, only 15% (n = 11) indicated that they had been warned about the increased RRD risk related to myopia, suggesting that three‐quarters of patients were not actively informed by their eye care professionals. Conclusion: RRD symptom awareness is significantly related to a higher rate of macula‐on RRDs and better visual outcomes after treatment. There is limited awareness of increased RRD risk in myopic RRD patients. These findings suggest that counselling individuals at high risk of RRD about related symptoms is inadequate and better counselling may improve visual outcomes following RRD treatment.

Ex vivo ocular perfused models have been described in the past and were applied in different mammalian species as platforms to test drug delivery systems and surgical techniques. However, reproduction of those methods is challenging because extensive and precise description of the protocols used is lacking. In this technical paper we provide a detailed description of all the steps to be followed from the enucleation of porcine eyes to cannulation of the ophthalmic artery and perfusion. This model can contribute to the reduction of use of living animals in ophthalmology research, whereas as opposed to in vitro models, it preserves tissue complexity and integrity., (Copyright © 2019 The Authors.

Objective: To identify symptoms in patients with isolated posterior vitreous detachment predictive for the later development of retinal breaks., Methods: Two hundred eighty consecutive patients seen with symptoms of posterior vitreous detachment were prospectively asked to complete a questionnaire detailing their symptoms. At the time of presentation and follow-up, all patients had a full ophthalmologic examination including slitlamp biomicroscopy with Goldmann 3-mirror contact lens after maximal pupil dilatation. Two hundred fifty patients with an isolated posterior vitreous detachment were included and reexamined 6 weeks after the onset of symptoms. If small retinal or vitreous hemorrhages were detected, patients were reexamined after 2 weeks., Results: In 13 patients (5.2%) a retinal break was detected at reexamination. Logistic regression analysis with backward elimination revealed that symptoms of flashes in combination with clouds or multiple (>10) small dots at the time of the initial examination or an increase of floaters after the initial examination were statistically significantly (P<.001) related to the development of new breaks. These symptoms had a predictive value for the presence or absence of a new retinal break of 75.0% and 99.6%, respectively., Conclusions: Specific symptoms can identify patients at risk for the development of new retinal breaks after an initial examination in which no abnormalities were found and may obviate the need for follow-up appointments of patients not at risk.
