For example, if the eye care specialist plots only two isopters on the Goldmann perimeter, CPT would call that intermediate, based on its description of 92082. Finally, maximal levator function shows how high the patient can lift his or her lid voluntarily. Meanwhile, various custom Humphrey field tests so far reported in the literature, which test more points superiorly have limitations such as not testing points in inferior field,9, 10 which may induce bias, and threshold static testing,8, 11 which is time consuming. Some people with glaucoma do not notice any problems with their vision, but the visual field test shows that peripheral vision is being lost.

As the gold standard of perimetry, Humphrey Field Analyzer 3 (HFA3) is your trusted diagnostic partner. This was performed without complication. This correlation of MRD1 with visual field loss suggests that formal testing of the latter is not essential, and the impact of ptosis on visual fields may be confirmed by the clinician. The inferior field test serves as a reference, but is not used in the analysis. Your best bet is to check with your local carrier to determine if billing guidelines exist.

The extent of visual field defect associated with ptosis, dermatochalasis or a combination ranged between 0 to 35 points missed with a median of 19 (mean 19, SD 9.32). Photographs of frontal plane and oblique view; Flash photography documents the MRD and corneal light reflex as well any eyelid skin resting on the eyelashes. Maximal Levator Function: 12mm O.D., 12mm O.S. In the meantime, to ensure continued support, we are displaying the site without styles If results show a significant amount of eyesight is affected by ptosis, corrective surgery (blepharoplasty) becomes medically necessary rather than cosmetic. Her medical history was also positive for diabetes mellitus, long-term heterotopic ossification joint pain (>45 years). Automated visual field testing (taped and untaped) is required. Best-corrected visual acuity measured 20/20 O.D. It has a wider angle and can capture peripheral field defects. Begin with a thorough medical and ocular history. 0000002851 00000 n series when the diagnostic testing does not confirm glaucoma. Other patients with obvious ptosis who struggle to sit at the analyzer or maintain adequate concentration should not be denied surgery on the basis of this test alone. Dermatochalasis is a condition in which there is excess upper eyelid skin. As this test is a screening test rather than a threshold test, it may not be able to identify a visual field defect associated with more subtle degrees of ptosis.11 Therefore, the few patients complaining of a reduced visual field who have no measured defect could be offered ancillary tests, such as photographs, a threshold visual field test or a quality of life questionnaire. Visual field testing can detect blind spots A visual field test can determine if you have blind spots (called scotoma) in your vision and where they are.

Example 2: The eye care physician performs visual fields for a patient who presents with high intraocular pressure, open angle, and the VFs confirm the presence of small scotomas in the areas of the VF related to glaucoma. Ophthal Plast Reconstr Surg 1992; 8: 250255. Here, well only talk about the Humphrey visual field perimeter, which is used for 99% of visual field tests.
