The visual fields of both eyes overlap; therefore each eye is tested independently. The patient should cover their right eye with their right hand (vice versa when testing the opposite eye). With the examiner seated directly across from the patient, the patient should direct their gaze to the...
There are a variety of methods to measure the visual fields. During an eye exam, visual field testing is performed on one eye at a time, with the opposite eye completely covered to avoid errors. In all testing, the patient must look straight ahead at all times to accurately map the perip...
Visual field testing detects defects in the field of vision, testing the function of the retina, optic nerve and optic pathways. Formal visual field tests are generally performed using automatedperimetry, i.e., measurement of the ability to see points of light at varying locations on a curved...
Types of visual fields testing include automated perimetry, frequency doubling perimetry, electroroetinogram and confrontational. Automated perimetry has the patient fix on a source of light so response to the presence of objects in different field view areas can be tested. Frequency doubling pe...
In kinetic testing, a moving target of varying size and luminance is presented to the patient. Manual kinetic perimetry is more flexible and interactive for the patient, and it provides the opportunity to evaluate the far peripheral visual field [1]. Also in existence is a semi-automated ...
This factor also may be a possible influence factor to the relatively high rate of unreliable and/or abnormal fields in our patient population even after the third test. Indeed, as found in another study32 with FDT perimetry, there was a progressive increase in the number of reliable VF ...

We have fixed a fatal internal compiler error caused by unnamed structs whose fields are referenced from SAL annotations. Fixes a rare crash when analyzing templated code that uses __uuidof. Fixed an issue that caused C++ static analysis results to sometimes not display correctly in the FixIt act...
Discussion This is the first clinic-based study describing the contribu- tion of Humphrey visual field testing to the management of glaucoma in Africa. Our results may be summarized as follows: 1) the majority of visual fields performed in this patient popu- lation were reliable; 2) most ...
