Visual acuity

A measure of the sharpness or clarity of vision, typically assessed using an eye chart. Visual acuity is expressed as a fraction, with 20/20 being considered normal vision, and lower fractions indicating poorer vision.

Verteporfin

A photosensitizing agent used in photodynamic therapy (PDT) for the treatment of certain types of macular degeneration. Verteporfin is injected intravenously and activated by laser light to selectively destroy abnormal blood vessels in the retina.

Visual field

The entire area that can be seen when the eyes are fixed on a central point. Visual field testing is performed to assess the extent and pattern of peripheral vision, which can be affected by conditions such as glaucoma and optic nerve disorders.

Vision therapy

A type of treatment that involves exercises, techniques, or devices aimed at improving or enhancing visual skills, such as eye coordination, focusing, and tracking. Vision therapy is often used in the management of certain eye conditions, such as strabismus and amblyopia.

Visual evoked potential (VEP)

A diagnostic test that measures the electrical activity of the visual pathways in response to visual stimuli. VEP testing is used to evaluate the integrity of the visual pathway from the eyes to the brain, and can help diagnose conditions affecting the optic nerve and visual cortex.

Viral conjunctivitis

An inflammation of the conjunctiva, the thin membrane that covers the white part of the eye and the inner surface of the eyelids, caused by a viral infection. It is highly contagious and can cause redness, watering, and discomfort in the eyes.

Vitreous detachment

A natural age-related process in which the vitreous gel in the eye separates from the retina. Vitreous detachment can cause floaters, flashes of light, and rarely, retinal tears or detachment.

Vitrectomy

A surgical procedure to remove the vitreous gel from the eye and repair retinal detachment or other eye conditions.

Vitreous humor

Vitreous humor is a clear, gel-like substance that fills the space between the lens and the retina in the eye
