What does CVF mean in MEDICAL

CVF stands for confrontation visual field. It is a type of eye evaluation used to measure peripheral vision. The test compares the ability of both eyes to see objects on each side while focusing on a target in the center.

Anyone with symptoms or signs of eye disease may need to have a CVF exam. Your doctor may order a CVF if you are experiencing changes in vision or if other tests suggest an underlying problem.

During the test, one eye is covered while the patient focuses on a central point and follows instructions from the examiner. The examiner will then present targets located at various points within your peripheral vision, such as letters or numbers written on cards held up at different angles from the centre position. You will be asked if you can see what was presented in each location.

No, there should not be any pain associated with this test procedure. A mild pressure sensation may occur during some types of evaluation where instruments are placed near your eyes but this should not cause discomfort or pain.

Depending on how many tests need to be done, it usually takes around 10-20 minutes for each eye to be tested separately with each result being recorded by hand onto graph paper or stored digitally using computer technology such as Octopus Perimeter software packages.
