What this trial studies

This study aims to develop an automated and objective method for measuring intraocular pressure (IOP) using both standard ophthalmic equipment and portable prototypes. Patients attending routine eye appointments will be recruited to undergo IOP measurements using four different methods, including the traditional Goldmann Applanation Tonometry and two innovative prototypes. The goal is to enhance the accuracy and repeatability of IOP measurements, which are crucial for diagnosing and managing glaucoma. The study will assess the effectiveness of these methods in a clinical setting.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are presenting for routine eye exams.

Not a fit: Patients with a history of corneal scarring or active eye infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate and reliable eye pressure measurements, improving glaucoma diagnosis and management.

How similar studies have performed: While traditional methods like Goldmann Applanation Tonometry are well-established, the automated approaches being tested in this study are novel and have not been widely implemented.
