Gonioscopy

Gonioscopy

Gonioscopy is a diagnostic procedure used to detect and measure the angle between the cornea and iris in order to diagnose and monitor glaucoma. It involves using a specialized mirrored device to gently touch the surface of the eye and examine the angle where the cornea and iris meet.From: Computer-Aided Glaucoma Diagnosis System [2020], Glaucoma Detection Using Optical Coherence Tomography Images: A Systematic Review of Clinical and Automated Studies [2022]

Gonioscopy is a test for examining the angle where the cornea meets the iris, using a special mirrored device to gently touch the surface of the eye. Whether this angle is open or closed can show the doctor what type of glaucoma there is and how severe it may be.

There are various tests conducted for the detection and progression monitoring of glaucoma. A tonometer is used by ophthalmologists to measure intra ocular pressure (IOP). Gonioscopy is a glaucoma detection test that helps ophthalmologists to measure the angle between the iris and cornea. Gonioscopy facilities help an ophthalmologist to determine the type of glaucoma. Fundoscopy is used by an ophthalmologist for the interior examination of eyes: the main regions that can be analyzed are optic nerve head, macula, peripheral and central retinal. Optical coherence tomography (OCT), scanning laser polarimetry (SLP), and confocal scanning laser ophthalmoscopy (CSLO) are imaging techniques used for the quantitative assessment of RNFL and optic nerve head. However, the CSLO only provides the optic disc analysis. SLP measures peripapillary RNFL thickness, whereas OCT provides assessments of both the RNFL and optic disc. Thus, optical coherence tomography techniques are the most commonly used imaging technology for the detection and management of glaucomatous eyes.
