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.
