Static perimetry within 30[degrees] is a standard in glaucoma diagnostics and monitoring; kinetic perimetry is preferred in neuroophthalmological conditions, extended visual field defects, and low visual acuity.
Moreover, in the remaining two patients, static perimetry was impossible to obtain due to very poor visual acuity.
(4) The Royal College of Ophthalmologists guidelines recommend visual field testing every six months using either Goldmann kinetic perimetry or Humphrey or Octopus static perimetry
. (5) However, the physical limitations of CP can make accurate visual field assessment a challenge and careful and regular monitoring is essential.
Visual field testing can be performed by a number of different techniques including confrontation (at the bedside), tangent screen, Goldman kinetic perimetry, and automated static perimetry
. 3The sensitivity of confrontation techniques is about 20% for detection of arcuate field defects and about 70% for detection of hemianopia when compared to Goldman.
