The perimetric compression test (CPT) is a method for the early diagnosis of glaucoma. It is based on examining the patient's visual field using a perimeter, which measures the change in light reflex depending on the pressure on the eyeballs.
To perform CPT, the patient sits on a chair and closes his eyes. The doctor puts special glasses on the eyes, which allow him to regulate the pressure on the eyeballs using a special device. The doctor then begins to slowly increase the pressure on the eyes until the patient feels discomfort or pain.
During this process, the doctor monitors changes in the patient's visual field and records the results. If the patient experiences changes in the visual field, this may be a sign of glaucoma.
CPT is one of the most accurate methods for diagnosing glaucoma and can help doctors detect the disease in the early stages, when it has not yet manifested itself clinically.
The compression perimeter test (CPT) is a modern diagnostic method in ophthalmology that allows you to accurately and quickly determine the early stages of glaucoma. Compression applied to the eyeball distorts the functioning of the optic nerve, and in a healthy eye, compression of the retinal cells does not lead to a change in its activity. With the development of glaucomatous lesions, the signal from the affected part of the network
