Retinal ganglion cell axon damage accounts for approximately 40% of early defects detected by standard automated perimetry
, the gold standard for following glaucoma patients.
A small scotoma, determined by MP-1 perimetry
and detected on face fields, is shown in Figure 2.
When adjusted for baseline difference in Humphrey perimetry
10-2 MD values, a dose-dependent improvement (p=0.
A comparison of MMT data with kinetic manual perimetry
showed good correspondence of the detection aspect of the task (Trauzettel-Klosinski, Biermann, Hahn, & Weismann, 2003).
Subclinical visual involvement in multiple sclerosis: a study by MRI, VEPs, frequencydoubling perimetry
, standard perimetry
, and contrast sensitivity.
1) There also exists a wide variety of alternate methods for assessing visual function in AMD including contrast sensitivity, colour vision, shape discrimination and preferential hyperacuity perimetry
Results are influenced by many factors for example, patient age, media opacities, visual acuity, perimetry
technique and patient reliability.
Repeat Goldmann perimetry
also documented a decrease in the enlarged blind spot (Figure 2 b).
2004) and that peripheral field devices that are used in many driver-screening centers (Keystone View Tester and Titmus Vision Tester) are poorly correlated with the results of standard Goldmann perimetry
tests (Szlyk, Fishman, Master, & Alexander, 1991).
7) Harle and Evans cautioned against using short wavelength automated perimetry
(SWAP) in migraine.
This debate has been sharpened by recent studies showing ocular hypertensive patients can lose as many as 50% of their optic nerve axon despite having normal kinetic visual fields, (4) or as many as their 35% of their ganglion cells despite normal automated threshold perimetry
