Summary
Peripheral visual field testing aids glaucoma diagnosis, supporting central findings in 21.8% of cases. This extra data, while valuable, adds significant time to patient examinations.
Area of Science:
- Ophthalmology
- Visual Science
Background:
- Glaucoma diagnosis relies heavily on visual field testing.
- Assessing both central and peripheral visual fields is crucial for comprehensive evaluation.
Purpose of the Study:
- To evaluate the diagnostic utility of peripheral visual field testing.
- To compare the additional information from peripheral testing with the time investment.
Main Methods:
- Utilized an automated perimeter (Fieldmaster 5000) for visual field assessment.
- Measured peripheral visual fields with kinetic stimuli and central fields (30 degrees) with static stimuli.
- Included 600 eyes from 323 patients with glaucoma or suspected glaucoma.
Main Results:
- Peripheral field abnormalities supported central findings in 131 eyes (21.8%).
- Peripheral testing provided primary diagnostic information in 25 eyes (4.2%) with normal or equivocal central fields.
- Peripheral field measurements constituted approximately 28% of the total testing duration.
Conclusions:
- Peripheral visual field testing offers valuable supplementary diagnostic information in glaucoma evaluation.
- The diagnostic yield of peripheral testing must be weighed against the increased examination time.
