- W3029529706 abstract "Objective To observe the effect of ophthalmotonus intervention on ocular hemodynamics in patients with ischemic ophthalmopathy (IOP).Methods 106 IOP patients (106 eyes) were enrolled in this study,including 74 eyes with nonarteritic anterior ischemic optic neuropathy (NAION),20 eyes with retinal artery occlusion (RAO) and 12 eyes with ocular ischemia syndrome (IOS).The patients were randomly divided into ophthalmotonus intervention group and control group.There were 37 NAION eyes,10 RAO eyes and six IOS eyes in each group.The patients of ophthalmotonus intervention group received lowering intraocular pressure treatment in addition to the basic therapy to reduce the intraocular pressure to ≤12 mm Hg (1 mm Hg=0.133 kPa) or decreased by 7-8 mm Hg,or in a 20％-30％ reduction.The patients of control group avoided lowering intraocular pressure treatment.The arm-retinal circulation time (A-RCT) and the peak systolic velocity (PSV),end diastolic velocity (EDV) and resistance index (RI) of ophthalmic artery (OA),central retinal artery (CRA) and short posterior ciliary arteries (PCA) before and one week after treatment were comparatively analyzed by fluorescence fundus angiography (FFA) and color Doppler flow imaging.Results The differences of A-RCT before treatment in ophthalmotonus intervention group and control group in NAION,RAO and IOS patients were not statistically significant (t=0.869,0.119,0.000; P＞0.05).The differences of PSV (OA:t=0.586,0.040,0.067; CRA..t=0.285,0.057,0.775; PCA:t=0.658,0.653,1.253),EDV (OA:t=0.274,0.080,0.093; CRA:t=0.781,0.077,0.277; PCA:t=0.200,0.209,0.299) andRI (OA:t=0.121,0.153,0.138; CRA:t=0.172,0.242,0.642; PCA:t=1.053,1.066,0.266) of OA,CRA and PCA before treatment in ophthalmotonus intervention group and control group were not statistically significant (P＞0.05).Compared with control group,A-RCT shortened obviously (t =2.573,2.236,2.607 ; P＜ 0.05) in ophthalmotonus intervention group one week after treatment.Compared with control group,PSV (OA:t=2.367,2.368,2.267; CRA:t=0.775,1.927,2.775; PCA:t=2.253,2.353,2.353) and EDV (OA:t=2.303,2.236,2.503; CRA:t=2.277,2.377,2.577; PCA:t=2.299,2.399,2.299) of OA,CRA and PCA increased obviously (P＜0.05),RI of OA,CRA and PCA decreased obviously (OA:t=2.238,2.387,2.228; CRA..t=2.342,2.442,2.542; PCA:t=2.266,2.366,2.266; P＜0.05) one week after treatment in treatment group.Conclusion Ophthalmotonus intervention can improve the ocular hemodynamics in IOP patients.Key words: Eye; Ischemia/therapy; Hypotension, controlled; Hemodynamics" @default.
