For example, it can detect patients at risk of having a drop in OPP after anti-VEGF injections, improving safety.8 The FMD can also measure accurate and repeatable applanation forces that compensate for the effect of corneal thickness and curvature.9 FMD can be a promising diagnostic tool for glaucoma screening and glaucoma severity assessment.10 Our case showed that the FMD may also be superior to relying on historical vascular risk factors alone in determining the need for further vascular testing. The gene discussed is VEGFA; the disease is glaucoma.
