Most attacks of acute angle closure glaucoma involving pupillary block occur in individuals that are unaware that they have narrow iridocorneal angles. Practitioners using any of the above drugs should be aware of their potential to cause acute angle closure.
The new miniaturized HIFU EyeOP1 delivery device seems to be effective in decreasing IOP in patients with refractory glaucoma. The technology offers a good safety profile. (ClinicalTrials.gov number, NCT01338467.).
Purpose. To determine the prevalence of ocular surface diseases and identify risk factors in a population of patients receiving antiglaucomatous eyedrops over the long term. Methods. An observational cross-sectional study was designed to investigate ocular surface signs and symptoms using simple clinical tools. An ocular surface disease intensity score was calculated based on 10 questions regarding ocular surface symptoms and signs with a 4-grade scale. Patients were classified into 3 groups (A, B, and C) according to this total score. A multinomial logistic regression was performed in order to identify risk factors for surface disease. Results. In an overall population of 516 patients, 49% belonged to group A, 30% to group B, and 21% to group C. The multivariate analysis showed that the following factors were correlated with the severity of ocular surface disease: patient age, number of daily eyedrops, past topical treatment changes for ocular intolerance (found in the history of 40% of the patients), intraocular pressure (found to be significantly higher in patients with more severe ocular surface disease), and glaucoma severity. Conclusions. Patients treated for primary open-angle glaucoma or ocular hypertension often have ocular surface diseases, more often and more severely in older patients receiving more drugs and presenting with more severe glaucoma. These high prevalence values might therefore have consequences on the burden of the disease in terms of adherence to treatment and quality of life.
NPDS appears to be an effective and safe filtering procedure for lowering IOP and could be an alternative to trabeculectomy in open angle glaucoma with the advantage of having fewer complications.
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.
