斜视手术和遮盖疗法后斜视性弱视的患儿对视物变形的适应——遮盖疗法与视物变形

Background: Reduced visual acuity and deficient binocularity are well-known sym.tom. of am.lyopia. Distortions of visual space perception were reportedm.re recently in strabism.c am.lyopia. This study investigated whether strabism.s surgery and occlusion therapy have an influence on these deficits in am.lyopic children. m.terials and m.thods: Two aspects of vertical alignm.nt of am.lyopic eyes,nam.ly spatial distortion and spatial uncertainty,were investigated prospectively in 13 children (m.an age 6 years 9 m.nths) before and after strabism.s surgery and in 12 children (m.an age 6 years 11 m.nths) during 6 m.nths of occlusion therapy. Results: A different im.act of the two types of therapeutic intervention was observed: a slight (statistically not significant) increase of uncertainty was the only change noticed postoperatively after 1 week,spatial distortions were not affected. During occlusion treatm.nt,both clear shifts of alignm.nt and a decrease of uncertainty occurred. Conclusions: The geom.try of visual space of am.lyopic children showed m.difications due to altered visual experience during treatm.nt,m.st obviously during occlusion therapy. These changes are evidence for unknown features of plasticity of the am.lyopic visual system.initiated by treatm.nt.

斜视性弱视儿童空间定位的缺陷

世界核心医学期刊文摘（眼科学分册） 2005年第4期1卷 32-32页

作者： fronius m. Sireteanu R. Zubcov A. 齐翔云 Dept. of Paediatric Ophthalm.logy University Eye Hospital Theodor- Stern- Kai 7 60590 Frankfurt Main Germany

Background: Besides loss of visual acuity and binocularity, spatial localization deficits (com.rising both increased spatial uncertainty and spatial distortions) are an im.ortant feature of strabism.c am.lyopia. Although they have been extensively investigated in adult am.lyopes, there are still m.ny open questions concerning their substrate and relationship to clinical param.ters. Our aim.was to develop a procedure for assessing vertical alignm.nt, which enabled us to find out whether children with strabism.c am.lyopia had sim.lar spatial localization deficits, and their relation to the children s clinical condition. m.thods: Vertical alignm.nt was assessed in children by com.aring the visual direction in space of three loci along the vertical m.ridian, separated by 5 deg of visual angle. We tested alignm.nt in the am.lyopic and dom.nant eyes of 32 strabism.c and in both eyes of 35 control children from.4.5 to 10 years, together with a careful orthoptic exam.nation. Results: In the am.lyopic eyes, increased uncertainty and system.tic distortions outside the norm.l range occurred. Large angles of deviation and pathological fixation patterns were necessary, but not sufficient conditions for gross spatial deficits to occur. The fellow dom.nant eyes showed spatial localization sim.lar to norm.l eyes. Conclusions: Children with strabism.c am.lyopia exhibited localization deficits and relationship to clinical data sim.lar to those in adult am.lyopes. These data are im.ortant for further investigations about the substrate, plasticity and the clinical relevance of perceptual distortions.
