Eye Examining Tangent Screen

Eye Examining Tangent Screens are a type of ophthalmic instrument used in eye examinations. They are part of the supply class Ophthalmic Instruments, Equipment, and Supplies, which falls under the supply group Medical, Dental, and Veterinary Equipment and Supplies.

Tangent screens are typically large, flat screens that are placed at a specific distance from the patient during an eye examination. They are used to assess a patient's visual field, which is the extent of their peripheral vision.

During the examination, the patient focuses on a central point on the screen, while the examiner moves a small target along the perimeter of the screen. The patient is then asked to indicate when they can see the target, which helps determine the boundaries of their visual field.

Tangent screens are commonly used in the diagnosis and monitoring of various eye conditions, such as glaucoma, retinal detachment, and visual field defects. They are an essential tool for ophthalmologists and optometrists in evaluating a patient's visual function and detecting any abnormalities.

In summary, Eye Examining Tangent Screens are ophthalmic instruments used to assess a patient's visual field during an eye examination. They are part of the supply class Ophthalmic Instruments, Equipment, and Supplies, which belongs to the supply group Medical, Dental, and Veterinary Equipment and Supplies.
