  • Treatment of central retinal artery occlusion by thrombolysis via super-selective ophthalmic artery catheterization

    ObjectiveTo investigate the therapeutic method and effect of thrombolysis via superselective ophthalmic artery catheterization treating central retinal artery occlusion (CRAO).Methods9 patients with CRAO were treated by urokinase infusion via superselective ophthalmic artery catheterization with Seldinger technique.ResultsIn the 9 patients, the visual acuity was improved to different extent in 8, and remained unchanged in 1. No complications was found during the treatment in any patients.ConclusionsThrombolysis via super-selective ophthalmic artery catheterization for CRAO can improve the visual acuity of most of the patients in different degrees. No positive relation exists in clinical therapeutic effect, time of onset, quantity of urokinase and the visual acuity before the treatment. The method of thrombolysis via super-selective ophthalmic artery catheterization for CRVO is safe and reliable.(Chin J Ocul Fundus Dis, 2005,21:22-24)

  • Relationship between retinal circulation time and visual loss in patients with central retinal artery occlusion

    Objective To investage the relationship among the visual loss, the disease course, and retinal circulation time in patients with central retinal artery occlusion (CRAO). Method The data about the central vision, disease course, and results of fundus fluorescein angiography (FFA) of 99 patients (99 eyes) with CRAO were statistically analyzed. Results Between 2 days and 21 days after the occurrence of CRAO, the disease course didnrsquo;t relate to the central visual loss (Pgt;0.05). In the retinal circulation, a correlation was found between the time of fluorescein perfusion and the central visual loss (Plt;0.05) but not between the time of arm-retina circulation and the central visual loss (Pgt;0.05). Conclusion In the duration of retinal circulation, the time of fluorescein perfusion in retinal artery relates to the central visual loss; the longer the duration is, the worse the vision is.

  • The effect of internal boundary membrane detachment on visual acuity in the affected side of non-arteriotic central retinal artery occlusion

    Objective To observe the clinical and imaging features of non-arteriotic central retinal artery occlusion (NA-CRAO) with internal boundary membrane detachment (ILMD), and to analyze its relationship with visual prognosis. MethodsA retrospective clinical study. A total of 88 patients with NA-CRAO hospitalized in Department of Ophtalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) from January 2014 to June 2023 were included in the study. Best corrected visual acuity (BCVA), optical coherence tomography (OCT) and fluorescein fundus angiography (FFA) were performed. The BCVA test used the international standard visual acuity chart, which was statistically converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. OCT observed the presence of ILMD and the thickening of the inner retina and the disappearance of anatomical stratification. FFA recorded arm-retinal circulation time (A-Rct) and retinal arterion-distal filling time (FT), and observed ciliary retinal artery, fluorescein retrograde filling, cotton spots, luciferin nodal filling, macular non-perfusion, capillary fluorescein leakage, optic disc strong fluorescence, choroidal background weak fluorescence and other characteristics. According to whether there was ILMD, the patients were divided into ILMD group and non-ILMD group, with 44 cases and 44 eyes respectively. The two groups received the same treatment. The follow-up time was 30 days after treatment. The clinical, FFA characteristics and BCVA before and after treatment were compared between the two groups. t-test was used for comparison between groups. ResultsIn ILMD group and non-ILMD group, there were 43 cases of male and 1 case of female, respectively, and the proportion of male was significantly higher than that of female. Before and after treatment, the logMAR BCVA of ILMD group and non-ILMD group were 2.35±0.42, 2.01±0.46, 1.47±0.60, 0.77±0.49, respectively. There were significant differences in logMAR BCVA between the two groups before and after treatment (t=8.025, 12.358; P<0.001). Before treatment, A-Rct and FT in ILMD group were longer than those in non-ILMD group, and the difference was statistically significant (t=3.052, 3.385; P<0.05). After treatment, there was no significant difference (t=1.040, 1.447; P>0.05). The proportion of ciliary retinal artery and cotton plaque in ILMD group was lower than that in non-ILMD group. There was no significant difference in ciliary retinal artery between the two groups (χ2=-0.961, P>0.05), but there was a significant difference in cotton wool plaque between the two groups (χ2=-3.364, P<0.05). Compared to the non-ILMD group, The proportion of retrograde fluorescein filling in retinal artery (χ2=-2.846), segment filling (χ2=-3.907), macular non-perfusion (χ2=-6.656), capillary fluorescein leakage (χ2=-4.367), optic disc strong fluorescence (χ2=-3.525) and choroidal background weak fluorescence (χ2=-2.276) increased, the difference was statistically significant (P<0.05). ConclusionsIn patients with NA-CRAO, compared with those without ILMD, those with ILMD have more severe retinal ischemia and worse BCVA before and after treatment. ILMD is one of the poor prognostic markers of NA-CRAO vision.

  • Changes of some peripheral blood cells in patients with non-arteritis central retinal artery occlusion

    ObjectivesTo explore the changes of some peripheral blood cells related to inflammation in patients with non-arteritis central retinal artery occlusion (NA-CRAO). MethodsA retrospective clinical study. From July 2019 to July 2021, a total of 218 patients with NA-CRAO hospitalized (NA-CRAO group) in Department of Ophthalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) and 218 patients with routine physical examination (control group) during the same period were included in the study. There were no significant differences in age (t=0.60), sex composition ratio (χ2=0.83) and body mass index (t=0.77) between the two groups (P>0.05). 0.2 ml fasting peripheral blood was collected from the subject, and white blood cells (WBC), neutrophils (NEUT), lymphocytes (LYMPH), red blood cells (RBC), RBC distribution width (RDW), platelets (PLT), mean PLT volume (MPV), and large PLT ratio (PLCR) were detected. The NEUT/LYMPH ratio (NLR) and PLT/LYMPH ratio (PLR) were calculated. t test was used to compare measurement data between groups. Multiple logistic regression analysis was performed for blood cells with P<0.05. The receiver operating characteristic curve (ROC curve) was used to calculate the area under the curve (AUC) and 95% confidence interval (95%CI) of each inflammatory indicator, and the optimal cutoff value was determined according to the Jorden index (sensitivity+specificity-1). ResultsCompared with control group, WBC, NEUT, NLR, RDW, PLR were increased in NA-CRAO group, while RBC and LYMPH were decreased, with statistical significance (t=9.68, 12.43, 9.47, 3.64, 5.54, 5.18, 0.46; P<0.001). There was no significant difference in PLT, MPV and PLCR between the two groups (t=0.32, 1.56, 0.84; P>0.05). Multivariate logistic regression analysis showed that NLR was a possible risk factor for the occurrence of NA-CRAO (odds ratio=2.51, 95%CI 0.780-0.859, P=0.031). ROC curve analysis showed that the AUC predicted by NLR was 0.819, the optimal critical value was 3.05, and the sensitivity and specificity were 59.2% and 92.7%, respectively. ConclusionsIn peripheral blood cells of NA-CRAO patients, NEUT is significantly increased and LYMPH is decreased. NLR is a possible risk factor for NA-CRAO.

  • 二维超声和脉冲多普勒对高血压患者眼动脉血液动力学的研究

    本文应用二维超声和脉冲多普勒技术(2DU-PWD)对57例正常人和37例高血压病人的视网膜中央动脉(CRA)、睫状动脉(CA)和眼动脉(oA)的血液速度进行测定。结果表明高血压病人的频谱形态、流速及时相测定均与正常人有显著差异(Plt;0.05~0.1),并与眼底病血管病变一致。平均动脉压(MBP)与峰值血流速度(SPV)和平均血流速度(Vm)呈明显负相关(r=-0.53,-0.55),与脉动指数(PI)及阻力指数(RI)有明显相关关系(r=0.72,0.44)。认为2DU-PWD 技术是一种简便可靠的无创性诊断方法。 (中华眼底病杂志,1992,8:20-23)
