Reliability Evaluation of Intraocular Pressure One Day After Vitreoretinal Surgery Comparing Goldmann Applanation Tonometry to Icare and Accupen

What this Trial Is About

Researchers are evaluating the accuracy of two portable instruments, Icare and Accupen, for measuring intraocular pressure (IOP) compared to the gold standard, Goldmann applanation tonometry (GAT), one day after vitreoretinal surgery. The study aims to determine if these simpler, easier-to-use methods provide reliable IOP measurements in post-operative patients, helping to potentially replace the more cumbersome GAT method. This prospective controlled study enrolls 67 patients who have undergone vitreoretinal surgery. Participants will have their IOP measured using three devices: GAT, Icare, and Accupen, in a randomized order during their one-day post-operative visit. A resident ophthalmologist will perform two pressure measurements with each device and calculate the average for comparison. The study focuses on verifying if the portable methods match the accuracy of GAT in this surgical context. During the single post-operative visit, medical history related to the eye surgery and diagnosis will be recorded. The main outcome is to assess the agreement of IOP measurements among the three devices one day after surgery. The study will also evaluate the reliability and validity of the portable devices across different pressure levels. Participation involves this one-time measurement and medical review, with no long-term follow-up required.
