ObjectiveThe prevalence of glaucoma is rising due to an increasing aging population. Because of its insidious and irreversible nature, glaucoma has gradually become the focus of attention. We assessed primary open angle glaucoma, the most common type of glaucoma, to study its present status, global trend, and state of clinical research.MethodsPublications from 2000 to 2021 in Web of Science database were retrieved and analyzed by bibliometrics. VOSviewer and Citespace were used for analysis.ResultsA total of 6,401 publications were included in this review, and we found that the number of publications increased from 139 in 2000 to 563 in 2021. American researchers have published the most papers and had the highest h-index and the most citations, while the Journal of Glaucoma has published the most papers on this topic. Some key researchers, contributing institutions, their partnerships, and scientific masterpieces were identified. The publications we reviewed fall into seven categories: publications on intraocular pressure, normal tension glaucoma, risk factors, the trabecular meshwork, optical coherence tomography, surgery, and mutation. Clear study hotspots were described, which began with epidemiology and transitioned to pathogenesis and diagnosis and then to treatment.ConclusionStudies on primary open angle glaucoma extend well beyond ophthalmology to biochemistry molecular biology, general internal medicine, pharmacology, pharmacy, science technology, and other areas. Interest, research and publications on primary open angle glaucoma are on the rise.
Post‐laser in situ keratomileusis (post‐LASIK) ectasia (PLE) is one of the most serious complications after refractive surgery, mainly manifested as progressive thinning and trembling thinning of the cornea, accompanied by increased myopia and astigmatism. The mechanisms behind mainly include genetic risk factors and external environmental factors such as eye rubbing and cornea surgery. In order to achieve the goal of reducing the incidence of ectasia, preoperative screening strategies need to be continuously improved, through the collection and assessment of genetic and environmental risk factors. Although previous preoperative screening methods did not have a uniform standard, the emergence of artificial intelligence (AI) can help us process a large amount of information and make rational use of the data. By using high‐fidelity finite element modelling, differences in preoperative and postoperative strain distributions can be observed, which can predict the risk of postoperative ectasia. In this review, we describe the incidence, aetiology, prevention and treatment of PLE for the purpose of comprehensive management. In terms of treatment, corneal collagen cross‐linking has been widely used to treat progressive keratoconus and other ectasia disease, either as a preventive measure during surgery or as a therapeutic modality after surgery to prevent progression of corneal dilation. Although the standard Dresden protocol has been identified as the gold standard treatment for corneal dilatation, a series of refinements, investigations and long‐term studies have been conducted in recent years. Thus, understanding the factors involved in delaying the onset and slowing progression of cornea ectasia will be key to reducing the incidence worldwide.
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.
