轻度帕金森病患者视网膜神经纤维层厚度变化的特点分析

摘要

目的：：观察轻度帕金森病( Parkinson’s disease,PD)患者视网膜神经纤维层( retinal nerve fiber layer,RNFL)厚度变化的特点。方法：采用光学相干断层扫描( optical coherence tomography,OCT)对我院门诊诊断为早期PD的15例15眼患者和18例18眼正常对照者进行以视盘中心为圆心、直径为3.46 mm的环形扫描。扫描分为颞侧、上方、鼻侧、下方、颞下、颞上、鼻下、鼻上8个象限进行。对比分析两组受检者8个象限的视网膜神经纤维层( retinal nerve fiber layer,RNFL)厚度及平均RNFL厚度。结果：正常对照组颞侧、上方、鼻侧、下方、颞下、颞上、鼻下、鼻上RNFL厚度和平均RNFL厚度分别为83.2±17.5,132.7±17.4,83.7±22.3,141.5±15.3,117.9±24.5,120.8±21.2,110.2±27.7,109.6±20.6,109.9±8.5µm,早期PD患者颞侧、上方、鼻侧、下方、颞下、颞上、鼻下、鼻上RNFL厚度和平均RNFL厚度分别为68.7±13.5,128.1±25.3,76.5±17.8,128.6±13.2,103.3±14.1,102.6±23.7,96.6±15.0,101.2±20.9,102.3±11.9µm。两组比较,下方、颞侧、颞下、颞上RNFL厚度和平均RNFL厚度差异有统计学意义(t=2.595,2.700,2.153,2.330,2.131；P=0.014,0.011,0.040,0.026,0.041)。结论：早期PD患者下方、颞侧、颞下、颞上及平均RNFL厚度较正常者明显变薄。%Abstract•AlM:To study the thickness changes of retinal nerve fiber layer ( RNFL) in Parkinson's disease ( PD) .•METHODS:Fifteen eyes of 15 PD patients in early stage and 18 eyes of 18 controls were chosen to take RNFL examination by optical coherence tomography ( OCT ) . Circular scans were taken around the optic nerve head (diameter = 3. 46mm) to record the features of RNFL. Scanning areas included eight quadrants of the temporal, superior, nasal, inferior, inferior-temporal, superior-temporal, inferior-nasal and superior-nasal quadrant. RNFL thickness was comparatively analyzed in eight quadrants and the average level in two groups.•RESULTS: RNFL thickness in two groups in temporal, superior, nasal , inferior, temporal- inferior, temporal-superior, nasal-inferior, nasal-superior were: ( control/PD) 83. 2 ± 17. 5μm/68. 7 ± 13. 5μm, 132. 7 ± 17. 4μm/128. 1 ± 25. 3μm, 83. 7 ± 22. 3μm/76. 5 ± 17. 8μm, 141. 5 ± 15. 3μm/128. 6± 13. 2μm, 117. 9 ± 24. 5μm/103. 3 ± 14. 1μm, 120. 8 ± 21. 2μm /102. 6 ± 23. 7μm, 110. 2 ± 27. 7μm/96. 6 ± 15. 0μm, 109. 6 ± 20. 6μm/101. 2 ± 20. 9μm. The average RNFL thickness in controls was 109. 9 ± 8. 5μm while it showed 102. 3 ± 11. 9μm in PD group. RNFL thickness in inferior, temporal, inferior-temporal, superior-temporal and the average RNFL thickness were statistically different in two groups ( t= 2. 595, 2. 700, 2. 153, 2. 330, 2. 131;P= 0. 014, 0. 011,0. 040,0. 026,0. 041).•CONCLUSlON: RNFL thickness in inferior, temporal, inferior temporal, superior temporal and the average RNFL thickness are significantly thinner in mild PD than those in the controls.
