【摘要】： 目的：定量研究中心注視性弱視患者的紅綠色覺功能,探討L/M錐細(xì)胞相對敏感性在屈光發(fā)育中的作用。 方法：門診收集82名中心注視的既往弱視／屈光不正患者,依次對雙眼進行下列檢查：眼位檢查、眼部裂隙燈檢查、直接檢眼鏡檢查、注視性質(zhì)、主導(dǎo)眼、暗室下色盲鏡(HMC Anomaloskop Typ 47700)進行Rayleigh顏色匹配、標(biāo)準(zhǔn)照明條件下標(biāo)準(zhǔn)對數(shù)視力測量裸眼視力(UCVA)、主覺驗光、最佳矯正視力(BCVA)、根據(jù)既定入組標(biāo)準(zhǔn),分為弱視組(43例86眼,弱視59眼)、既往弱視組(24例48眼,既往弱視40眼)、非弱視組(15例30眼)。使用SPSS 13.0統(tǒng)計軟件分析不同組間、組內(nèi)Rayleigh匹配結(jié)果的差別及其與等效球鏡、BCVA、主導(dǎo)眼等因素的關(guān)系。 結(jié)果：中心注視性弱視眼的色覺異常率為0.017%。弱視組(59眼)的紅綠匹配點值較非弱視組(30眼)大,差異存在統(tǒng)計學(xué)意義(p0.05),與等效球鏡、最佳矯正視力無顯著相關(guān),紅綠匹配范圍無統(tǒng)計學(xué)差異。弱視組內(nèi),單眼弱視(23眼)與雙眼弱視(16眼)的Rayleigh匹配結(jié)果無統(tǒng)計學(xué)差異。單眼弱視者的弱視眼與健眼比較,紅綠匹配范圍較大,差異有統(tǒng)計學(xué)意義(p0.05),紅綠匹配點無顯著差異。非弱視組內(nèi),非主導(dǎo)眼的紅綠匹配范圍比主導(dǎo)眼大(p0.05),既往弱視組也顯示出同樣的差異,但無統(tǒng)計學(xué)意義。 結(jié)論：中心注視性弱視眼的紅綠色覺無明顯異常,紅綠色覺與形覺在P通路上相獨立。中心注視性弱視眼M錐相對L錐敏感,但目前并未發(fā)現(xiàn)其與屈光發(fā)育顯著相關(guān)。非優(yōu)勢眼對中長波長色光的分辨力較優(yōu)勢眼差,提示中樞對非優(yōu)勢眼的色覺感知存在抑制。
[Abstract]:Aim: to quantitatively study the red and green color perception function of central fixation amblyopia and to investigate the role of the relative sensitivity of L / M cone cells in refractive development. Methods: 82 patients with amblyopia and ametropia were collected from the outpatient clinic. The following examinations were performed on the eyes in turn: eye position examination, eye slit lamp examination, direct ophthalmoscope examination, fixation nature, dominant eye. The standard logarithmic visual acuity (UCVA), principal optometry and best corrected visual acuity (BCVA) were measured under standard illumination. According to the established criteria, they were divided into amblyopia group (43 cases, 86 eyes). Amblyopia (59 eyes), amblyopia group (24 cases, 48 eyes), past amblyopia group (40 eyes) and non amblyopia group (15 cases, 30 eyes). The difference of Rayleigh matching results among different groups and the relationship between Rayleigh matching results and BCVA and dominant eyes were analyzed by SPSS 13.0 software. Results: the abnormal rate of color vision in central fixation amblyopia was 0.017. The red and green matching point of amblyopia group (59 eyes) was larger than that of non-amblyopia group (30 eyes), the difference was statistically significant (p0.05). In amblyopia group, the Rayleigh matching results of monocular amblyopia (23 eyes) and binocular amblyopia (16 eyes) had no statistical difference. The range of red and green matching was larger in amblyopic eyes than that in healthy eyes (p0.05), but there was no significant difference between red and green matching points. In the non-amblyopia group, the red and green matching range of the non-dominant eye was larger than that of the dominant eye (p0.05). The same difference was found in the previous amblyopia group, but there was no statistical significance. Conclusion: the red and green color perception of central fixation amblyopia is not abnormal, and the red green color vision and form vision are independent in P pathway. M cone is sensitive to L cone in central fixation amblyopia, but there is no significant correlation between M cone and refractive development. The resolution of non-dominant eye to medium and long wavelength color light is worse than that of dominant eye, which suggests that the central nervous system can inhibit the color perception of non-dominant eye.
