Filter by:The aim of this study is to evaluate the efficacy and safety of Tocilizumab as second/third line treatment in patients with Active Moderate-to-Severe Corticosteroid-Resistant Thyroid Eye Disease.
The aim of this study is to compare between peribulbar block and subtenon block as an adjunct to general anesthesia in children undergoing strabismus surgery on oculocardiac reflex (OCR), post-operative analgesia and postoperative vomiting. Both techniques will be compared to intra-operative intravenous (IV) paracetamol combined with general anesthesia as a sole anesthetic technique.
Although postoperative infectious endophthalmitis and toxic anterior segment syndrome (TASS) rarely happen, they can threaten sight and are considered complications of intraocular and cataract surgery1. Reusing surgical supplies during cataract surgery, especially in developing countries, will have a treble impact in lowering the financial costs of surgery, the emissions of greenhouse gas, and environmental waste. Nearly half the waste of cataract surgery is recyclable, as reported by a prospective Malaysian study 8. Despite the increasing evidence of reusing the operative supplies, numerous healthcare professionals may be reluctant to consider it due to worries about cross-contamination among patients2. According to the Aravind Eye Care System (AECS) in Tamil Nadu, India, endophthalmitis rated 0.02% in over a million consecutive cataract cases despite the observation that cannulas, irrigation/ aspiration tubing, gowns, surgical gloves, irrigating bottles, as well as topical and intraocular drugs are normally recycled to cut cost and waste3,4. On the other hand, health care plays a key role in climate change, as well as financial and environmental waste2. Cataracts are the leading cause of blindness and visual impairment worldwide, making cataract surgery one of the most performed surgical procedures5. The carbon footprint of cataract surgery, especially phacoemulsification, is a significant research field6-8. In the United Kingdom, cataract surgery releases 180 kg of CO2- equivalents per eye, causing over half of the emissions due to obtaining large disposable medical equipment9. In ACES, phacoemulsification generated 5.9 kg of carbon emissions4. In comparison to the United Kingdom and the United States of America, the cataract surgery's low rates of infection in AECS were accomplished with 1/10 supply costs and 1/20 global warming emissions6. Being the most performed operation, cataract surgery and ophthalmology, in general, can meaningfully influence lowering environmental and economic waste in their surgical services1. The aim of this work is to show if reusing the operative supplies to reduce financial costs, especially in developing countries, and to lower global warming and climate change will affect the rate of postoperative endophthalmitis after cataract surgery
In this study, the investigators will make the only upper flap either from the internal limiting membrane or from the epiretinal membrane to cover the full thickness macular hole.
Autologous blood for primary and recurrent holes
The objective of this application is to illustrate the core constituents of the ocular surface microbiome, describe factors that promote colonization, and assess the ocular microbiome's role in the health of the anterior segment. We will conduct a prospective, observational cohort study, including a longitudinal analysis of the ocular microbiome in adults.
AMD (age-related macular degeneration), is the leading cause of blindness in individuals over the age of 55. There is no cure for wet-AMD but anti-VEGF treatments significantly minimize the vision loss over time. To study the correlation between anti-VEGF injection bevacizumab (Lucentis), visual acuity, macular thickness and last but not least reading speed in wet-AMD patients. The study was conducted on 50 eyes of 50 wet-AMD patients. Subjects were monthly treated with an intra-vitreal Lucentis injection for 3 months; further injections were given when a loss of 5 or more letters of visual acuity was observed and/or when the retinal thickness in the affected macular area increased by 100 µm. In addition to a full ophthalmological examination reading speed was investigated via the Radner reading chart before and 3 months after treatment. The collected data was analyzed using paired t-tests.
The aim of this study is to evaluate the anatomical and refractive parameters following a single-step transepithelial photo-refractive keratectomy (T-PRK) without the addition of mitomycin-C for the treatment of high myopia of 6 diopters or more.
Ocular damage is found in the 3rd rank of extra intestinal manifestations (MEI) Potentially serious functional complications (see uveitis and risk of blindness) requiring rapid management Rare uveitis in the literature (0.5% -3%), study on a large sample to assess their prevalence in patients with IBD at the Nancy CHRU and describe all the ocular manifestations that can be found.
