The spectral reflectance of the nerve fiber layer of the macaque retina.

摘要: This paper reports the first quantitative measurements of reflectance spectrum nerve fiber layer (NFL) retina. An arcuate defect in NFL two macaque monkeys was produced by photocoagulating a small spot near optic disc. Imaging fundus reflectometry at 8 wavelengths then used to measure fundal reflectances and intact NFL. The alone determined subtracting bare from adjoining with data were corrected for transmission ocular media published values density monkey cornea lens. Lens absorption measured Purkinje images differed little values. can be characterized that has same shape all points along an region but decreases absolute as thickness decreases. changes between 680 560 nm, rises lambda-n 460 where n = 2.5-3.1. reported here begin provide understanding empirically methods enhancing visibility have implications retinal densitometry.
