Most CCGs require all patients to undergo visual field testing (preferably automated perimetry) if their Marginal Reflex Distance-1 (MRD1) is not 1. The percentage of grid seen was calculated for both eyelid positions using the devices. A minimum 12 degree or 30 percent loss of upper field of vision Superior visual field impairment ranges from 20% loss of visual field for mild ptosis to 64% in advanced/severe cases where the eyelid is located in the middle of the pupil. The process is fast and painless. Patients completed field testing faster than reported times for automated or Goldmann testing.

Upper blepharoplasty (removal of upper eyelid skin) and/or repair of blepharoptosis should be considered functional/reconstructive in nature when the upper lid position or overhanging skin or brow is sufficiently low to produce functional complaints, usually related to visual field impairment whether in primary gaze or down-gaze reading. However, if they're smart, the designers would incorporate some false prompts, i. Other symptoms may result from deficits in diplopia, accommodation, abnormality of eyelid, tearing, and cosmetic problems due to corneal opacity, glare sensitivity, color vision, night vision, binocularity, stereopsis, and suppression. 1. 92081 is the lowest level of visual field test.
