RESUMO
BACKGROUND: To characterise and compare ocular pathologies presenting to an emergency eye department (EED) during the COVID-19 pandemic in 2020 against an equivalent period in 2019. METHODS: Electronic patient records of 852 patients in 2020 and 1818 patients in 2019, attending the EED at a tertiary eye centre (University Hospitals of Leicester, UK) were analysed. Data was extracted over a 31-day period during: (study period 1 (SP1)) COVID-19 pandemic lockdown in UK (24th March 2020-23rd April 2020) and (study period 2 (SP2)) the equivalent 2019 period (24th March 2019-23rd April 2019). RESULTS: A 53% reduction in EED attendance was noted during lockdown. The top three pathologies accounting for >30% of the caseload were trauma-related, keratitis and uveitis in SP1 in comparison to conjunctivitis, trauma-related and blepharitis in SP2. The overall number of retinal tears and retinal detachments (RD) were lower in SP1, the proportion of macula-off RD's (84.6%) was significantly (p = 0.0099) higher in SP1 (vs 42.9% in SP2). CONCLUSION: COVID-19 pandemic related lockdown has had a significant impact on the range of presenting conditions to the EED. Measures to stop spread of COVID-19 such as awareness of hand hygiene practices, social distancing measures and school closures could have an indirect role in reducing spread of infective conjunctivitis. The higher proportion of macula-off RD and lower number of retinal tears raises possibility of delayed presentation in these cases. Going forward, we anticipate additional pressures on EED and other subspecialty services due to complications and associated morbidity from delayed presentations.

BACKGROUND: Patients with spinocerebellar ataxia 7 (SCA7) are known to develop ocular abnormalities. The purpose of this study was to characterize these abnormalities in greater detail and with the aid of newer quantitative technologies. METHODS: Seven patients with SCA7 diagnosed by genetic analysis at La Paz Hospital (Madrid, Spain), a country-wide referral center for ataxias, were included in the study. Demographic data and ocular features were recorded from a complete ophthalmologic examination, specular microscopy, corneal topography (Pentacam), and optical coherence tomography (OCT). RESULTS: All 7 patients had decreased visual acuity associated with varying degrees of macular pigmentary changes on ophthalmoscopy. All 7 had lower corneal endothelial cell densities than expected for their age, and 5 had increased corneal volume, although none had corneal edema. Patients with mild disease showed retinal thinning at the fovea. In patients with more advanced disease, retinal thinning was present also in the outer zone of the macula. Mean peripapillary retinal nerve fiber layer thickness was decreased in all patients; however, the temporal quadrant was spared except in advanced disease. CONCLUSIONS: This study of 7 patients with SCA7 amplifies previous reports of ophthalmic abnormalities in this condition by providing data from specular microscopy, corneal topography, and OCT. Abnormalities were present in the anterior and posterior ocular segments, as well as in eye movements and pupillary reactions. Visual dysfunction, present in all patients, was associated with retinal thinning. Decreased endothelial cell density and increased corneal thickness were common.

OBJECTIVE: To describe the survival and outcome of maxillary sinus cancer in patients managed with surgery and post-operative radiotherapy during the last 10 years in our hospital. PATIENTS AND METHOD: Descriptive, retrospective, non-randomized study of 23 patients with cancer of the maxillary sinus managed at the Vigo University Hospital Complex, Spain, with radical surgery and post-operative radiotherapy, between 1995 and 2004. RESULTS: The 3-year actuarial survival was 47.8% and the adjusted actuarial survival was 60.8%. Permanent local tumour control was achieved in 60.8% of cases (14/23). Local tumour recurrence was the main cause of treatment failure (33.3%; 4/12). The most significant prognostic factors affecting local tumour control and survival were: clinical stage (P< .031), suprastructural location of the tumour (P< .001), and presence of positive resection margins (P< .001). CONCLUSIONS: Local recurrence was found to be very high and generally the main cause of death. New treatment protocols should be assessed.
