Abstract
Two-photon vision is a newly discovered mechanism of the perception of pulsed near-infrared laser beams as a color stimulus corresponding to approximately half of the laser wavelength (PNAS 111(50), E5445–E5454). Based on this phenomenon, a new visual field test instrumentation – two-photon microperimetry, has been developed (BOE 10(9), 4551–4567). This study shows that two-photon perimetry gives more reproducible results than one-photon perimetry for standard threshold finding strategies. This unquestionable advantage of the nonlinear vision-based visual field testing technique may benefit the clinical assessment of retinal disease progression and treatment efficiency.
