Oculocutaneous albinism type 4 (OCA4) is characterized by hypopigmentation of the skin and hair plus the characteristic ocular changes found in all other types of albinism, including nystagmus; reduced iris pigment with iris translucency; reduced retinal pigment with visualization of the choroidal blood vessels on ophthalmoscopic examination; foveal hypoplasia associated with reduction in visual acuity; and misrouting of the optic nerves at the chiasm associated with alternating strabismus, reduced stereoscopic vision, and an altered visual evoked potential.

All lenses were classified using the lens opacities classification system Ⅲ based on four categories: nuclear color, nuclear opalescence, cortical cataract and posterior subcapsular cataract. ALs were measured 20 times with an IOL Master, 5 times with an IOL Master version 4.0, and 5 and 15 times with an IOL Master version 5.0 and the results were recorded.

IOL Master 5.0版相對于傳統(tǒng)IOL Master采用了組合信號分析技術国产真实露脸乱子伦对白，將多個低信噪比（signal-to-noise ratio，SNR）的單次眼軸測量結果進行疊加組合超级碰人人操人人，使噪音相互抵消人人操人人爱爱，而反映黃斑中央凹位置的信號被放大，從而提高了SNR欧美肏大屄。

fovea：凹

此外還有一種主要負責分辨細致的線條和色彩的視錐(cone),在一個大人在看東西的時候,需要動用視網(wǎng)膜(retina)的中央凹(fovea)里的5萬個視錐細胞,當然,對于嬰兒來說,別說視錐遠不夠成熟了,他連那個中央凹都還沒有完全形成呢.

fovea centralis：中央凹

在視神經(jīng)盤顳側約3.5mm處,有一黃色小區(qū),稱黃斑(macula lutea),其中央的凹陷,稱中央凹(fovea centralis),為視覺(辨色力日韩三级AV网站、分辨力)最敏銳的部分. 活體時,視網(wǎng)膜略呈紅色,死后呈灰白色.

central fovea：中央凹

核心提示: 黃斑(macula lutea)直徑約3 mm,中央有一個直徑約1.5 mm的橢圓形中央凹(central fovea). 凹底部視網(wǎng)膜厚度僅O.1 mm,面積500~550μm2,此處只有約30 000個視錐細胞及放射狀膠質細胞組成的外界膜,無其他細胞和血管. 中央凹視錐細胞細而長,
