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.

疾病特征： 4型眼皮肤白化病（OCA4）的特点是皮肤和头发的色素减退以及所有白化病类型都有的典型的眼部改变，包括眼球震颤、虹膜色素减少而使其呈半透明状、视网膜色素减少而使得脉络膜血管在眼底镜检时可见、与中央凹发育不全导致的视敏度降低以及视神经交叉处路径错误引起的交替性斜视、立体感降低和视觉诱发电位改变。

With the amount of anisometropia increased,the stereo-visual acuity decreased(t test P＜0.05) and the stereopsis visual acuity of "simple" hypermetropia decreased more significantly than that of "simple" myopia of the same amount.

立体视敏度随着屈光参差度数的增加而下降(t检验，P＜0.05)，相同程度的单纯远视性屈光参差比单纯近视性屈光参差立体视敏度下降更明显(t检验，P＜0.05)。

Methods: Add different power spherical lenses on 32 volunteers with normal binocular function to induce simple myopia(+1D,+2D,+3D),simple hypermetropia(-1D,-2D,-3D) and anisometropia.Assess the visual acuity,stereocontrast sensitivity and Worth 4 dots fusional function after inducing the anisometropia.

对双眼视功能正常的大学生志愿者32人采用在单眼前加不同度数正负球镜的方法，诱导单纯近视性(+1D，+2D，+3D)及单纯远视性(-1D，-2D，-3D)屈光参差，测定诱导屈光参差后的视力、立体视敏度及Worth四点融像功能。

For illusory border induction in the abutting grating illusion it is 5. 3%.(3) Random-dot stereograms are found to induce depth equally well in both display modes. The disparity threshold for perceiving depth in isochromatic random-dot stereograms levels off at a luminance contrast of 30%.

在亮度对比与等亮度颜色对比的条件下，受试者的立体视敏度不存在有统计学意义的差异；并且，当双眼接受不同颜色对比的等亮度立体图对刺激时，与亮度对比条件相比，受试者的立体视敏度也无明显差异。

Best-corrected visual acuity was 20/40 or better in 25 of 61 study eyes (41%). Primary retinal reattachment was attained in 60 study eyes (98%).

最佳矫正视敏度是20/40或者61例中25例(41%)较好。60例(98%)获得一期视网膜复位。

The latency and amplitude of P1 wave were recorded while the threshold stimulus was given.

阈刺激时PRVEP P1波潜伏期与视敏度的对数值存在较好相关性，回归方程如下：Y=-1.485＋0.008X（r=0.621，P〈0.01）。

The reversal rate of the stimuli was 2.9 Hz, and the contrast level was 100%. The latency and amplitude of P1 wave were recorded while the threshold stimulus was given.

结果：阈刺激空间频率与视敏度的对数值之间关系密切，两者之间的数学模型为■=－0.114－0.010X（r = 0.756，P﹤0.01），通过PRVEP推算的视敏度与平均视敏度之间无差别（P＞ 0.05）。

Diagnosis/testing. A diagnosis of ocular albinism is probable in the presence of congenital nystagmus, iris translucency, and significant hypopigmentation of the ocular fundus periphery in males with normal skin pigmentation and foveal hypoplasia, reduced visual acuity, and aberrant optic pathway projection, as demonstrated by crossed asymmetry of the cortical responses on visual evoked potential. X-linked inheritance is documented by either a family history consistent with X-linked inheritance or the presence of typical carrier signs (irregular retinal pigmentation and partial iris transillumination) in an obligate carrier female.

诊断/检测。对于皮肤色素沉着正常、中央凹发育不全、视敏度降低以及视径投射异常（VEP，表现为视觉诱发电位中皮层反应的交叉不对称）的男性患者，当存在先天眼球震颤、虹膜半透明以及显著的眼基底层边缘色素减退的症状时，可被疑似诊断为眼白化病。X连锁性遗传则以存在与X连锁遗传一致的家族病史，或在一个应当为携带者的女性中存在典型的携带者迹象（视网膜色素沉着不规则以及部分虹膜透射）而被确认。

Methods To analyze the random-dots-stereopsis with near-to-zero, crossing and uncrossing disparity and Titmus stereopsis in 38 patients with intermittent exotropia.

对38例间歇性外斜患者，屈光矫正后，采用颜少明《数字化立体视觉检查图－2006年版》行近零视差立体视敏度、交叉视差和非交叉视差立体视检查，Titmus立体视检查，采用同视机随机点立体视画片检查远立体视。对检测结果进行分析。
