Two tests will be selected automatically for baseline, but these tests may be manually selected. Frequency doubling perimetry: This test utilizes varying intensities of a flickering image to analyze the visual field. Nerve fiber layer in glaucomatous hemifield loss: a case-control study with time-and spectral-domain optical coherence tomography. Kaushik S, Mulkutkar S, Pandav S, et al. J Neuroophthalmol. The HVF Test is an automated static perimetry test using an HVF analyser, in which static illuminated targets briefly appear in the field and patients indicate when a target is seen. Research shows significant sections of the inferior macula are associated with the inferior arcuate bundle (the majority of macular ganglion cells associated with the temporal quadrant of the optic nerve which is often preserved in early glaucomatous disease).7, If there is even a single central point defect with a 24-2 or 30-2 pattern, consider adding a 10-2 test to your assessment (figure 1). The major symptoms of Usher syndrome include retinitis pigmentosa (night-blindness and a loss of peripheral vision), and hearing loss. Visual field testing is an essential part of eye care, necessary for diagnosis and management of multiple conditions we see on a daily basis. IOP can be determined with the help of a tonometer, a device which lightly touches the surface of the (anesthetized) eye and measures the eye's resistance to indentation. The target may be a small disc on a stick, but most commonly the target is the doctor's hand holding up one or two fingers. 22. If a patient with visual field loss is being monitored with serial examination, use the mean deviation (MD), pattern standard deviation (PSD) and visual field index (VFI) to track progression. False positives are primarily important in tests that have defectsthey are not a reason to invalidate an otherwise unremarkable or clear visual field test. Depending on the suture used for skin closure, sutures are removed at the discretion of the surgeon usually within 1-2 weeks after surgery.

The European Glaucoma Society (EGS) recommends visual field testing several times yearly for the first two years after diagnosis.13 This will help establish a rate of progression and identify the roughly one in six glaucoma patients who progress at a dangerously high rate (greater than 2dB per year).14 If this frequency is not reasonable in your practice setting, then test at least twice yearly during the first two years.

Swedish Interactive Thresholding Algorithm (SITA) Standard in 24-2 pattern with stimulus size III is generally the preferable test for most routine glaucoma and neurological testing. The visual fields should demonstrate a significant loss of superior visual field and potential correction of the visual field by the proposed procedures(s). Klin Monbl Augenheilkd.

Incisions are generally well hidden within the upper eyelid crease, and sutures are used to approximate skin edges. Understand the roles of the technician and physician. Extensive RNFL loss (~30%) is necessary to produce a visual field defect. Age-related macular degeneration (AMD) is a disease that gradually destroys the central vision.

MD will be less sensitive in early-stage glaucoma and other cases with localized field loss. Tape: Double-sided tape for the eyelid crease isn't a daily option for every eyelid (and some find the tape irritating), but it can be a great idea for a last minute event or photoshoot. Keep in mind that a patients results may appear to improve due to this grouping effect. The real utility of visual fields lies in tracking progression of glaucomatous defects.
