ABSTRACT
BACKGROUND:
Vitreous hemorrhage (VH) is a common ophthalmic disease with a high rate of blindness, which will seriously affect the quality of life of patients and bring great burden to patients' families and society. The treatment for VH contains medical therapy, lasers, and surgery. At present, there is no recognized western medicine with definite curative effect and little side effect for the treatment of VH. In most cases, PRP is not available to treat VH; intravitreal injection or surgical treatment is adopted as the primary therapy. However, in the long-term treatment, the effect of the above-mentioned treatment is not satisfactory, so many patients choose oral Chinese medicines, which has been widely used in China to treat VH. Numerous clinical trials have demonstrated that Chinese medicines can promote the absorption of VH and improve the visual function of patients. The purpose of this review is to evaluate the efficacy and safety of Chinese medicines in the treatment of VH and inform a decision aid for the clinical encounter between patients and clinicians. Besides, it is beneficial to establish a future research agenda.METHODS:
The systematic review will include all of the randomized controlled trials on the efficacy and safety of Chinese medicines for VH. Nine electronic databases, namely PubMed, Web of Science, EMBASE, the Cochrane Library, Google Scholar, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal database (VIP), and CBM, will be searched normatively on the basis of the rule of each database from the inception to August 31, 2019. We will also search registers of clinical trials, potential gray literature, and conference abstracts. There are no limits on language and publication status. The literature screening, data extraction, and quality assessment will be conducted by 2 reviewers independently. The reporting quality and risk of bias will be assessed by other 2 researchers. Standard of curative effect and total treatment efficacy rate were assessed as the primary outcome. The secondary outcomes will include the curative effect of single symptom and sign, the improvement rate of single auxiliary examination, withdrawal and reduction of western medicines in a course of treatment, maintenance of western medicines after the course of treatment, laboratory efficacy indexes. Meta-analysis will be performed using RevMan5.3 software provided by the Cochrane Collaboration.RESULTS:
This study will provide a comprehensive review based on current evidence of Chinese medicines treatment for VH in several aspects, including standard of curative effect, total treatment efficacy rate, the curative effect of single symptom and sign, the improvement rate of single auxiliary examination, withdrawal and reduction of western medicines in a course of treatment, laboratory efficacy indexes, total treatment efficacy, and safety, among others.CONCLUSION:
The conclusion of this study will provide evidence to determine whether Chinese medicines are an effective and safe intervention for patients with VH. ETHICS AND DISSEMINATION It is not necessary to obtain ethical approval for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences and will be shared on social media platforms. PROSPERO REGISTRATION NUMBER PROSPERO CRD42020152321.
