Various aspects of local anesthesia for cataract surgery, such as the anesthetic agents and their interaction with ocular nerve supply, anesthesia requirements, available clinical techniques and their inherent complications are reviewed. A comparative evaluation of clinical techniques in terms of efficacy, akinesia, and patient-perceived pain during both anesthesia administration and intraoperative cataract surgery is presented, along with the prevailing practice patterns of anesthesia techniques among refractive surgeons in the United Kingdom and United States. More randomized clinical trials are needed to facilitate statistical methods of metaanalysis to establish convincingly the overall benefits and efficacy of the various local anesthesia procedures in cataract surgery. The wide scope of the present review is of relevance in structuring ophthalmology and anesthesia specialist training programs for junior staff.
Our data suggest that Geliperm is as effective as Lacrilube in the prevention of exposure keratopathy in the critically ill. We also note that nursing staff must be fully trained in its application for eye care.
Objective The objective of this study was to determine the prevalence of ocular complications and blindness among leprosy patients presenting in the United Kingdom. Methods Observational prospective study. Results A total of 126 consecutive leprosy patients attending their ophthalmic visit were examined, out of which 18 patients were blind in one eye (14.3%) and five patients were blind in both the eyes (4.0%). Visual acuity of X6/18 was present in 96 patients (76.2%). A total of 65 patients (51.6%) had an ocular complication and 28 patients (22.2%) had a sight-threatening leprosy complication (lagophthalmos, severe corneal, or iris disease). The most common ocular complications were impaired lid closure (24 patients, 19%), impaired corneal sensation (20 patients, 15.9%), cataract (20 patients, 15.9%), mild corneal opacity (17 patients, 13.5%), and iris atrophy (17 patients, 13.5%). Impaired corneal sensation was associated with vision o6/18 (Po0.001, OR 13.5, 95% CI 5.14-35.44) and vision o3/60 (P ¼ 0.01 OR 6.42, 95% CI 2. 15-19.15). Impaired lid closure was significantly associated with increasing age (P ¼ 0.029, OR 1.039, 95% CI 1.0-1.08) and vision o3/60 (P ¼ 0.03, OR 6.06, 95% CI 1.81-20.24). Conclusion There is a significant rate of ocular complications and blindness seen in leprosy patients in the United Kingdom, and over one in five had a potentially sightthreatening ocular complication. Health professionals and all leprosy patients, including those cured of the disease, need to be aware that new eye symptoms and signs require prompt ophthalmology review to prevent avoidable blindness, due to the life-long risk of sight-threatening ocular complications.
Background: Malaria is currently diagnosed almost exclusively by microscopy in clinical laboratories. The introduction of rapid diagnostic tests (RDTs) may be useful in achieving rapid detection of malaria parasites, especially in situations where malaria is not often seen or where staff are inexperienced. Aim: To explore the use of RDT in UK laboratories. Methods: The current use of RDTs was surveyed in UK laboratories subscribing to the United Kingdom National External Quality Assessment Scheme blood parasitology and haematology schemes. Results: An overall survey response rate of 60.3% was seen. RDTs were found to be the preferred choice, either alone or in conjunction with microscopy in 31.2% of the samples examined during normal working hours and in 44.3% of the specimens examined on call. Conclusions: During on-call hours, the use of RDTs was observed to increase and RDTs changed the diagnosis in 12% of laboratories. No established protocol for RDT use was, however, observed in the UK. A protocol that needs to be validated in the laboratory setting is suggested.
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.
