Visual field tests are performed most often by eye doctors (optometrists and ophthalmologists) and neurologists. In cases where vision is reduced due to macular disease or central scotoma, use a diamond fixation targetthis displays four LEDs, allowing the patient to center their gaze between the targets. Electroretinography (ERG) is an eye test in which electrodes are placed on the cornea to measure electrical responses to light in an effort to detect abnormal retinal function. In patients who are glaucoma suspects, rely on the Glaucoma Hemifield Test (GHT) and the pattern deviation probability map. Risks of surgery include bleeding, bruising, scarring, asymmetry, need for additional procedures and retrobulbar hemorrhage. What types of specialists perform visual field tests?

If the first visual field test is read as abnormal or inconclusive because it was inaccurate, it may need to be repeated. Its important that the staff and physician maintain positive attitudes about the value of perimetry to encourage the patient to provide optimal results during testing. Visual field testing requires a minimal amount of time for most otherwise healthy patients, but it may be tiring or stressful for those who are ill or elderly. 2008;92(4):569-73. The 24-2 test protocol was designed to detect nasal and arcuate glaucomatous defects.

Purpose: To determine if preoperative Goldmann Visual Field (GVF) testing in patients with functional dermatochalasis accurately depicts the postoperative superior visual field (SVF) outcome. Ophthalmology. Blepharochalasis, Lacrimal gland herniation, Facial Nerve Palsy, Mechanical Blepharoptosis secondary to mass effect, Brow ptosis, and Floppy Eyelid Syndrome. Using progression analysis for nonglaucomatous field loss should be limited to VFI linear regression/trend analysis (the GPA change probability was designed for use in glaucoma). Trend-based progression will display linear regression analysis of VFI. Be on the look out formasquerading retinal and optic nerve conditionsConcomitant retinal or neurological disease can confound interpretation of visual field defects in many patients. It is weighted preferentially to central points and more resistance to cataract. Nerve fiber layer in glaucomatous hemifield loss: a case-control study with time-and spectral-domain optical coherence tomography. If a field shows scattered non-specific depressions, keep in mind that a diagnostic early glaucomatous defect is generally recognized as a repeatable cluster of three or more points on the same side of the horizontal meridian all reaching statistical significance (with one or more points having p<1% significance)the test points adjacent to the blind spot may be ignored. Doctors use a scalpel, scissors, cutting laser, or heat devices to cut the thin skin each doctor is a little different. You will cover one eye, and stare straight ahead with the other. Terms of Use. A thorough eye examination by an ophthalmologist is necessary to rule out diseases of the eye itself that may limit ameliorative options for patients bothered by dermatochalasis.
