On classifying 1000 senile cataracts it was found that in pure cataract forms - starting from the cortex - the typical grey senile cataract (cataracta supranuclearis) mostly occurs with a clear nucleus. The dense permeability cataract (cataracta subcapsularis) most frequently shows a dense grey clouding of the nucleus and in addition a still smaller increase in frequency with a clear nucleus. The cortex was also frequently clear when the nucleus of the lens was a dense cloudy grey. Conversley, starting from pure nuclear cataract forms, the dense grey clouded lens nucleus most frequently accompanies a permeability cataract (cataracta subcapsularis) and - with a second peak - with a clear cortex. The brown (black) nucleus (cataracta brunescens [nigral]) quite predominantly shows a clear cortex. If all the cataracts, including the mixed forms between the various cortical and nuclear cataracts are so classified that the percentage participation of the individual forms of cataract in the entire collective (including the mixed forms) is summarised, then the distribution is: Typical grey senile cataract (cataracta supranuclearis) in 23%. Permeability cataract (cataracta subcapsularis) in 36%. Light brown-grey nuclear cataract (mainly nuclear sclerosis) in 13%, grey nuclear cataract in 37%, brown nuclear cataract in 5%, mature cataract in 4%, hypermature cataract in 1%, intumescent cataract in 11%.
在对1000例老年性白内障进行分类时发现，在单纯性白内障类型中——从皮质性开始——典型的灰色老年性白内障（核上性白内障）大多伴有清晰的晶状体核。致密性通透性白内障（囊下性白内障）最常表现为晶状体核呈致密的灰色混浊，此外，晶状体核清晰的情况出现频率略低。当晶状体核呈致密的灰白色混浊时，皮质也常常是清晰的。相反，从单纯核性白内障类型来看，致密的灰色混浊晶状体核最常伴有通透性白内障（囊下性白内障），并且——出现第二个高峰——伴有清晰的皮质。棕色（黑色）晶状体核（棕色[黑色]白内障）大多表现为皮质清晰。如果将所有白内障，包括各种皮质性和核性白内障之间的混合类型都进行这样的分类，即总结出每种白内障类型在整个群体（包括混合类型）中的所占百分比，那么分布情况如下：典型灰色老年性白内障（核上性白内障）占23%。通透性白内障（囊下性白内障）占36%。浅棕灰色核性白内障（主要为核硬化）占13%，灰色核性白内障占37%，棕色核性白内障占5%，成熟性白内障占4%，过熟性白内障占1%，肿胀性白内障占11%。
