Evaluating the anterior chamber angle with gonioscopy is an essential part of evaluating patients at risk for glaucoma and neovascularization. It is also useful for patients with iris abnormalities or a history of trauma or ocular inflammation. Unfortunately, gonioscopy is underutilized by both optometrists and ophthalmologists.[1,2] Coleman, et al. found that less than half of Medicare beneficiaries underwent gonioscopy during a 4-5 year period prior to glaucoma surgery. It is critical to our patient’s ocular health that this change.
This article discusses the indications and contraindications to performing gonioscopy. Anterior chamber angle anatomy, types of gonioscopy lenses, a review of the procedure, and proper recording and insurance coding will also be covered. Finally, we will describe common variations of normal anterior chamber angles and angle abnormalities that are commonly seen in an eye care setting.
