If the eyelid or lashes obstruct the visual axis, the lid may be taped to the forehead to lift it out of the way. Ophthalmologists also use visual field tests to assess how vision may be limited by eyelid problems such as ptosis and droopy eyelids. During Humphrey Visual Field (HVF) testing, the patient places his head in the chinrest and fixes his gaze toward a central fixation point in a large, white . This process produces a computerized map of the visual field, outlining the areas where each eye can or cannot see. Blepharochalasis, Lacrimal gland herniation, Facial Nerve Palsy, Mechanical Blepharoptosis secondary to mass effect, Brow ptosis, and Floppy Eyelid Syndrome. The September 2010 CPT Assistant (Volume 20, Issue 9) provides direction on how to code for visual fields performed prior to eyelid surgery.
