摘要
目的分析探讨中心性浆液性脉络膜视网膜病变(简称中浆)患者病愈前后诸项视功能的受损特点和恢复情况。方法对25例中浆患者进行视力检测,并采用Amsler卡、色觉检查图、FACT对比敏感度测试卡和双眼影像不等检查图,分别检测患者的中心暗点和变形、辨色能力、对比敏感度和双眼同时视像差;并采用Titmus立体视检测卡、立体视觉检查图和同视机随机点立体画片检测患者的立体视功能,以远近6项指标均达到标准者则视为立体视功能正常。病变痊愈后重复上述检查。结果①患眼平均视力为4.80±0.17,对侧眼平均视力为5.08±0.08,两眼平均视力差异有极显著性(P<0.001)。痊愈后患眼平均视力为5.05±0.07,较病愈前差异有极显著性(P<0.001)。②Amsler卡检查24只患眼(占96.0%)有中心暗点和视物变形,病愈后4只眼(占16.0%)仍遗留轻度变形。③色觉检查14只患眼(占56.0%)辨色异常,其中以蓝紫色异常最明显;病愈后5只眼遗留(占20.0%)轻度蓝紫色弱。④患病期间双眼同时视像差平均为(2.80±1.87)%;病愈后平均像差为(0.42±0.48)%。⑤患病期间患眼各频段的对比敏感度值均较对侧眼下降,差异有极显著性(P<0.001)。病愈后患眼各频段敏感度值均达到正常范围,较患病时差异有极显著性,但仍较对侧眼低,在中高频区差异有显著性(P<0.05)。⑥Titmus立体图检测1例(占4.0%)患者无立体视,14例(占56.0%)立体视异常,10例(占40.0%)具有正常立体视。病愈后1例(占4.0%)患者立体视异常,余24例(占96.0%)为正常立体视。⑦采用立体视觉检查图和同视机随机点立体画片检测立体视功能,6项指标均正常者3例(占12.0%),余22例(占88.0%)患者均异常;病愈后20例(占80.0%)患者的6项立体视功能恢复正常,5例(占20.0%)仍异常。病愈前后的Amsler卡、辨色能力、同时视像差、对比敏感度以及立体视觉各项视功能等项检查结果差异均有显著性(P<
Objective To study the visual function characteristic of damage and recovery in CSC before and after healed.Methods Twenty-five patients who had recovered from CSC were examined visual acuity, central scotoma and metamorphosis, color vision, contrast sensitivity and binocular aniseikania with Amsler Grid, Wang Kechang color vision charts, FACT contrast sensitivity charts Liu Genian binocular aniseikonia charts, stereoscopic vision with Titmus stereoscopic charts, Yan Shaomin stereoscopic charts and random dot stereograms in the synoptophore. Normal stereoscopic vision is defined as five near and far stereoscopic vision are all normal. All the examinations were reexamined after CSC healed.Results ①Visual acuity of the affected eyes (mean 4.084±0.17) were significantly worse compared to the contralateral eyes (mean 5.076±0.08) (P<0.001). Visual acuity in recovered eyes (mean 5.052±0.07) were significantly better than the affected eyes (P<0.001). ②Twenty-four affected eyes (96.0%) had central scotoma and metamorphosis in Amsler Grid test. Four recovered eyes (16.0%) remained slight metamorphosis. Nineteen recovered eyes became normal. ③Of the CSC eyes, fourteen (56.0%) had a color defect, most of them in the blue-purple area. Of the recovered eyes, eighteen returned to normal color vision. Five eyes (20.0%) had slight blue-purple area color defect. ④The binocular simultaneous perception was (2.8±1.87)% (0～5%) in CSC active period and (0.42±0.48)% after CSC recovered. ⑤Contrast sensitivity of the affected eyes were significantly worse in all spatial frequencies compared to the contralateral eyes (P<0.001). In the recovered eyes, contrast sensitivity in high spatial frequencies remained worse compared to the contralateral eyes (P<0.05) even if their contrast sensitivity returned to normal range in all spatial frequencies. ⑥Of the active CSC eyes, one eye (4%) had no stereoscopic vision, fourteen eyes (56.0%) had abnormal stereoscopic vision, ten eyes had normal stereoscopic vision with Titmus stereo
