An American ophthalmologist has told his colleagues that visual field analysis software shows promise for the evaluation of glaucoma progression, but is limited by a lack of standards.
Dr. Adam Reynolds told a meeting of the American Society of Cataract and Refractive Surgery in Boston in April last that intuitive methods were “not too good”.
Addressing the meeting on Glaucoma Day, Dr. Reynolds said: “There’s poor agreement and there’s poor agreement among most of the automated event analysis methods. Trend-based analysis may be preferable… One of the problems is our evaluation of new methodology is hampered by a lack of standards.”
But he added that new and relatively unproven, trendbased analysis promises to enhance visual field testing as the primary method of tracking glaucoma progression.
“The Visual Field Index (VFI, Carl Zeiss Meditec) is approved by the U.S. Food and Drug Administration. VFI tracks the percentage of visual field loss and can predict the rate of progression at five years. Analysis of the rate of progression is based primarily on age, however, VFI is less sensitive to advancing cataract. “, Dr. Reynolds said.
Recently introduced technologies for tracking glaucoma progression includes the Humphrey Glaucoma Progression Analysis (Carl Zeiss).
