Is static perimetry a viable test for negative dysphotopsia?

CAPTION
Researchers have developed a potential new treatment for the eye disease glaucoma that could replace daily eye drops and surgery with a twice-a-year injection to control the buildup of pressure in the eye.

Netherlands: Whole threshold static perimetry with a Goldmann size III stimulation up to 60 degrees of eccentricity did not reveal any appreciable variations between measurements taken before and after intraocular lens (IOL) replacement or between patients with negative dysphotopsia and pseudophakic controls, a recent study has revealed.
The findings of the study, published in Optometry and Vision Science, indicates that this type of static perimetry cannot be used as a quantitative objective test for diagnosis or follow-up of patients with negative dysphotopsia.
There is a clinical requirement for a quantifiable test to reliably detect negative dysphotopsia, especially as the diagnosis is currently based on subjective descriptions provided by patients. This study rejects static perimetry as an appropriate evaluation tool in the search for a clinical test to objectify the shadow perceived in negative dysphotopsia. Furthermore, the purpose of this study was to test the use of static perimetry in the objective assessment and follow-up of negative dysphotopsia.
