Acupuncture for ophthalmoplegia: Protocol for a systematic review

BACKGROUND: Ophthalmoplegia is a disease that affects many people every year and is caused by reasons, such as cavernous sinus lesion, intracranial aneurysm, diabetes, and trauma. Acupuncture has been widely used to treat ophthalmological diseases especially ophthalmoplegia in China. Many clinical trials indicate that acupuncture may promote the recovery of extraocular muscles in ophthalmoplegia patients. We aim to conduct a meta-analysis to evaluate the efficacy and safety of acupuncture for ophthalmoplegia. METHODS: We will retrieve the literature from the following electronic databases, by March 31, 2018, such as PubMed, EMBASE, the Cochrane Library, Web of Science database, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, China Science and Technology Journal database, and Wanfang Database. We will also collect clinical trial registries, dissertations, grey literature, reference lists of studies, systematic reviews, and conference abstracts. Two people will review these articles, extract the data information, and assess the quality of studies separately. Data will be synthesized by either fixed-effects or random-effects model regarding to a heterogeneity test. The eyeball movement distance, size of fissure palpebrae, and the reduced degree of strabismus will be assessed as the primary outcomes. The secondary outcomes will be the size of the pupil, main symptom scores, ocular localization analysis, and functional impairment extent and safety. We will use the specific software called RevMan (version 5.3) to perform the meta-analysis. RESULTS: This study will provide a high-quality synthesis based on current evidence of acupuncture for ophthalmoplegia, especially its impacts on eyeball movement distance, size of fissure palpebrae, the reduced degree of strabismus, size of the pupil, main symptom scores, ocular localization analysis, and functional impairment extent and safety. EXPECTED CONCLUSION: Our systematic review will provide evidence to determine whether acupuncture is an effective and safe intervention for ophthalmoplegia patients. ETHICS AND DISSEMINATION: It is not necessary for this systematic review to acquire an ethical approval. This review will be disseminated in a peer-reviewed journal or conference presentation.
