Visual field testing with eyebrows relaxed, patient looking straight ahead, and the eyelids in normal relaxed position; Visual field is repeated with the eyelids taped up. With repeat visual field testing, most patients find their ability to maintain a steady straight-ahead gaze improves, thus improving the reliability of the results. While maintaining a straight-ahead gaze, the patient lets the doctor know when he/she can see the target in the peripheral vision. Trigger happy patients will push the response button in the absence of a stimulus.

Also, be aware that macular damage can present diffusely rather than sectorally. This prospective cohort study compared edge of the upper eyelid to central corneal light reflex distance (edge reflex distance [ERD]) preoperatively and postoperatively and examined the SVF, as measured by Goldmann perimetry , in single . If ptosis or dermatochalasis produce obstruction of the superior field, then the eyelids may be taped for testing (again, this should be noted on the field report to maintain consistency on all testing). Purpose: To determine if preoperative Goldmann Visual Field (GVF) testing in patients with functional dermatochalasis accurately depicts the postoperative superior visual field (SVF) outcome. One way a physician monitors glaucoma is to pre from periodic visual field tests. When severe field loss in advanced glaucoma is present, change to a 10-2 pattern to allow for more accurate assessment of the remaining visual field. 8. Theres also a risk of not seeing much change if a doctor does a blepharoplasty when a brow lift was needed. Ophthalmology. The visual field test is a subjective examination, so the patient must be able to understand the testing instructions, fully cooperate, and complete the entire visual test in order to provide useful information. The visual fields should demonstrate a significant loss of superior visual field and potential correction of the visual field by the proposed procedures(s). Some conditions, such as optic neuritis, may have such a high inherent variability that quantitative progression analysis is not possible. The examiners holds his fingers up, equidistant from him to the patient, in the patients inferior, superior, nasal, and temporal peripheral fields and asks the patient to tell him how many fingers are being held. The patient must keep their chin in the chin rest and forehead against the forehead rest. Prior to VFI, MD was used for progression analysis, but VFI provides a more accurate determination in the presence of cataract and cataract surgery.
