中心性浆液性脉络膜视网膜病变荧光造影与视力探讨

An investigation of the Relationship between Visual Acuity and Fundus Fluorescein Leakage in Central Serous Chorioretinopathy

目的探讨中心性浆液性脉络膜网膜病变(Central Serous Chorioretinopathy,CSC)荧光血管造影渗漏情况与视力关系。方法用Zeiss FF450眼底荧光造影摄像机对74例CSC患者进行眼底荧光血管造影,并结合临床进行分析。结果渗漏点位于黄斑中心区者16眼占20.51%,平均视力0.15;位于黄斑旁中心者53眼占67.95%,平均视力0.64;位于周围黄斑区者9眼占11.54%,平均为0.82。在同一眼内只有一个渗漏点者52眼占66.67%;有2个渗漏点者26眼占33.33%。圆点扩大型或墨渍弥散型29眼占37.18%,视力0.1～1.2,平均0.52;喷出型9眼占11.54%,视力0.1～0.5,平均0.21;窗样缺损型22眼占28.20%,视力0.3～1.2,平均0.62;混合型18眼占23.08%,视力0.2～1.2,平均0.64。渗漏面积大小,≤1/2 PD者42眼占53.85%,>1/2 PD者36眼占46.15%。结论渗漏点部位与视力有密切关系;渗漏点多对局部的损害较大有关;渗漏点类型对视力影响,以喷出型的为重;渗漏面积越大,视力损害越大(P<0.05)。

Purpose To analyze the relationship between fundus fluorecein angiograph leakage and visual acuity in the central serous chorioretinopathy. Methods 74 cases (78eyes) were examined as central serous chorioretinopathy by fundus fluorescein angiography wtih Zeiss FF450 retina angiography. Results Leakage sites: fovea 16 eyes ,20.51%, average visual acuity 0.15 and parafovea 53 eyes,67.95% average visual acuity 0.64 and perifovea 9 eyes, 11.54% .average visual acuity 0.82 .The number of leakage spot one leakage spot 52 eyes,66.67% ;and two leakage spots 26 eyes33.33% . The types of leakage sites: round type 29 eyes, 37.18 % , visual acuity 0.1～1.2, average 0.52; smokestack type 9 eyes. 11.54% , visual acuity 0.1～0.5,average 0.21;window defect type 22 eyes,28.20%, visual acuity 0,3～1.2,average 0.62; and mixed type 18 eyes, 23.08% , visual acuity 0.2～1.2,average 0.64.Leakage extent: ≤ 1/2PD 42 eyes, 53.85% ; and > 1/2PD 36 eyes,46.15% . Conclusion There is a close relationship between the leakage site and visual acuity. The more leakage spots, the woree visual acuity with lesion. The patients with fluorescein angiography of smokestack patterns were damage more in visual acuity than other types.The larger leakage extent,the worse the visual acuity with lesion. ( P < 0.05) .
