Suitable candidates for eyelid surgery are generally healthy and non-smokers. At first glance, the visual field defects look like dense arcuate scotomas. A droopy eyelid can affect one eye (unilateral ptosis) or both eyes (bilateral ptosis) and be mild or severe, intermittent or permanent. IF you do not, then you could be causing refractive scotomas to occur. D.

This increased frequency of testing can detect rapid disease progression much more quickly. The fovea is the area of greatest visual sen- sitivity, where the cone photoreceptor density is at its highest. 2 mm or less from the central corneal reflex to the upper eyelid margin or skin that overhangs the eyelid margin [pseudoptosis]) is helpful to demonstrate medical necessity. When performed reliably, the new 24-2C strategy becomes more useful than a standalone 24-2 or 10-2 for early glaucoma and optic neuropathy. The typical visual field for humans is 170 degrees: 70 degrees for central vision and 100 degrees for peripheral vision.
