Purpose: To present a rare case report of Onodi cell-associated optic neuropathy, conducting a review of the literature. Methods: A 36-year-old male presented with an 18-h history of acute deterioration of vision in his left eye (LE). Ophthalmic examination and Magnetic Resonance Imaging (MRI) were consistent with an Onodi cell-associated compressive optic neuropathy. Results: Despite immediate, successful surgical decompression, severe optic nerve atrophy and permanent visual loss occurred during early postoperative period. The reported case gives rise to different hypotheses regarding pathophysiology that may lead to irreversible blindness. A systematic review of the respective literature is provided attempting to compare different approaches in the management of Onodi cell-associated compressive optic neuropathy and assess their efficacy in the final visual outcome. Poor initial visual acuity (VA) may represent a bad prognostic factor. Moreover, age and gender do not seem to significantly influence the outcome. Conclusion: This report and associated literature review highlight the importance of the radiologic characteristics and early diagnosis in the final visual outcome of the Onodi cell-associated optic neuropathy. High level of suspicion is crucial for early diagnosis of mucoceles, which must be treated promptly by surgical and medical means to enhance visual recovery.
Clinical relevance: In the last months, the whole world is dealing with an unprecedented public health crisis due to COVID-19 outbreak. Consequently, many governments have implemented lockdowns on a national level, affecting, among others, ophthalmic surgical practice in a globe scale. Background: The aim of this study is to evaluate the impact of surgical theatre lockdown due to COVID-19 pandemic on the surgical performance of cataract surgeons. Methods: Intraoperative complications and surgical time of the first 160 cataract surgeries performed by eight consultants (20 cases each) after a two-month lockdown were recorded and analysed in a cross-sectional study. The results were plotted against the last 30 cases of each surgeon before the implementation of the lockdown (240 cases). Cataract surgeons were asked to rate their subjective perspective and difficulties faced after reopening through a questionnaire. Results: The average duration of all surgeries after the lockdown was 19.1 ± 6.2 minutes showing a 14% increase compared to the one before the lockdown (16.8 ± 5.1 minutes, p = 0.0001). The complications rate was 2.09% (5/240 cases) before the abstention and 3.12% (5/160 cases) after the abstention not yielding any statistically significant difference (p = 0.74). When complicated surgeries were excluded from the analysis, surgical time was still higher after the lockdown (18.9 ± 5.9 minutes) than before (16.6 ± 5.0 minutes, p < 0.0001). 37.5% of consultants (3/8) stated that the two-month abstention from cataract surgeries has affected their surgical skills somewhat or a lot, while 62.5% (5/ 8) reported being more careful in their first cases after the lockdown. Most complications occurred in the hands of one surgeon who stated to be very anxious upon restart. Conclusion: The operating theatres' lockdown due to COVID-19 pandemic did not seem to affect the intraoperative complications rate in cataract surgery. A slight increase of surgical duration was noted, while most surgeons reported being more careful upon restart.
A 33-year-old female was referred to the ophthalmology department after an accidental eye injury to her right eye during a hair removal session using alexandrite laser. Although she initially experienced no symptoms, when reexamined one and a half months later the bestcorrected visual acuity (BCVA) of the affected eye was 20/40 secondary to choroidal neovascularization confirmed by fluorescein angiography (FA) and optical coherence tomography (OCT). Intravitreal anti-vascular endothelial growth factor (VEGF) therapy (three monthly injections of aflibercept) led to complete regression of the neovascularization and functional recovery which was maintained at one-year follow-up post original injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
