Spectral sensitivity of human visual pathway and its clinical application 2. increment threshold spectral sensitivity of eyes with retinal detachment

Spectral sensitivity was measured on 108 [human] eyes with rhegmatogenous retinal detachment using a previously described method. In cases of foveal detachment with good vision (> 0.8) only the blue cone system was affected. The red and green cone systems were almost normal. In cases with visions from 0.3-0.7, all 3 cone systems revealed decreased sensitivity. After a successful operation, the sensitivities of red and green cone systems returned to normal within 1 mo. in most cases. The blue cone system showed prolonged disturbance for > 3 mo. in many cases. Similar selective suppression of the blue sensitivity was found in parafoveal nondetached zone neighboring the demarcation line which passed through the foveola. The suppression was quickly released after the operation. Such a functional disorder may be derived from subclinical retinal detachment produced by adjacent detached area of the retina.
