Risk of Ocular Adverse Events Associated With Use of Phosphodiesterase 5 Inhibitors in Men in the US.
Abstract
Importance
A number of case reports and small epidemiologic studies have quantified the risk of ocular adverse events associated with the use of phosphodiesterase type 5 inhibitors (PDE5Is). However, results have been conflicting, and epidemiologic data on the risk of serous retinal detachment (SRD) and retinal vascular occlusion (RVO) are not available.
Objective
To quantify the risk of SRD, RVO, and ischemic optic neuropathy (ION) associated with the use of PDE5Is.
Design, Setting, and Participants
This cohort study with a nested case-control analysis was performed using data obtained from the PharMetrics Plus database (IQVIA) from January 1, 2006, to December 31, 2020. Cohort members were followed up until the first diagnosis of SRD, RVO, or ION or termination of insurance coverage. For each case, 4 controls were matched by age and time of study entry using density-based sampling. Risk for regular users of PDE5Is was compared with that for nonusers, adjusting for potential confounding variables. Cases with diagnoses of SRD, RVO, and ION in the year before the cohort were excluded.
Main Outcomes and Measures
First diagnosis of SRD, RVO, or ION identified by International Classification of Diseases, Ninth Revision or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes. Adjusted incidence rate ratios (IRRs) with 95% CIs were calculated using conditional logistic regression, controlling for hypertension, coronary artery…
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 213 participants or records.
