Is Frequency Doubling Technology Perimetry Superior to Standard Automated Perimetry in Detecting Glaucoma?

August 18, 2010

An article in Ophthalmology gives further support to what was demonstrated earlier- Frequency Doubling Technology (FDT) visual fields¬†detect glaucoma earlier than Standard Automated Perimetry¬†(SAP). Fellow normal eyes (by SAP), found to have glaucoma by FDT, were much more likely to develop glaucoma than those fellow eyes with normal FDT. A clever study. For several years, I have been very happy to switch my patients who hate SAP to FDT. It’s faster and is better- period. I think it’s time SAP was simply abandoned- the only reason we use it is because it has the longest track record. Using that same reasoning, we should still be doing extracaps.
