ABSTRACT

@#AIM: To observe the improvement of ocular hemodynamics before and after intraocular pressure(IOP)intervention in patients with non-arteritic anterior ischemic optic neuropathy(NAION).<p>METHODS: Retrospective case series. Totally 92 patients(92 eyes)with NAION were admitted to the Department of Ophthalmology, Xi'an Fourth Hospital from July 2012 to September 2018. Forty-six patients received only basic treatment without IOP lowering treatment as the conventional treatment group. The other 46 patients were treated with brinzolamide eye drops combined with brimonidine eye drops to lower IOP on the basis of conventional treatment, as the IOP intervention group. Before and after treatment, the blood flow rate of the ophthalmic artery and central retinal artery were measured by color Doppler ultrasound. The IOP, best corrected visual acuity(BCVA), mean visual field defect(MD), retinal nerve fiber layer thickness(RNFLT), ophthalmic artery and central retinal artery peak systolic blood velocity(PSV), end-diastolic blood velocity(EDV), pulse index(PI)and resistance index(RI)were compared.<p>RESULTS: Before treatment, there were no significant differences in IOP, BCVA(LogMAR), MD, RNFLT, PSV, EDV, PI and RI between the two groups(<i>P</i>>0.05). After 14d of treatment, IOP, BCVA(LogMAR), MD and RNFLT of the two groups were significantly improved compared with those before treatment(<i>P</i><0.05), and the improvement effect of IOP intervention group was better, and the difference between the two groups was statistically significant(<i>P</i><0.05). The PSV, EDV, PI of ophthalmic artery and central retinal artery in the two groups were increased compared with those before treatment, and RI was decreased compared with before treatment; and the changes of PSV, EDV, RI, PI of ophthalmic artery and PSV, EDV, RI of central retinal artery in the IOP intervention group were more significant than those in the conventional treatment group(<i>P</i><0.05). <p>CONCLUSION: IOP intervention can significantly improve the ocular hemodynamic indexes and improve the visual acuity of patients with NAION.

ABSTRACT

Objective To analyze the effect of Fufang Xueshuantong capsule on glaucomatous optic atrophy and its influence on ocular hemodynamics.Methods 124 cases of patients with glaucomatous optic atrophy from April 2014 to December 2016 in our hospital were selected,and randomly divided into experimental group and control group according to the order of hospital admission , with 62 cases in each group.The control group was treated with nerve growth factor plus vitamin needling,the experimental group was treated with nerve growth factor and vitamin and compound Xueshuantong capsule.Observation and comparison the total effective rate, visual function (visual acuity, total gray value) improvement of the two groups of patients, as well as the changes of ocular hemodynamic parameters (systolic peak velocity, diastolic End-stage blood flow velocity, resistance index, pulsatility index).Results The total effective rate of the experimental group was 93.55%(58/62), the total effective rate of the control group was 70.97%(44/62), the total effective rate of the experimental group was higher than the control group (P <0.05)).After treatment, the visual acuity of the experimental group was significantly higher than the control group, the total gray value of the experimental group was significantly lower than the control group (P<0.05).The peak systolic velocity and end diastolic velocity in the experimental group were significantly higher than those in the control group (P<0.05).The resistance index and pulsatility index in the experimental group were lower than those in the control group (P<0.05). Conclusion Compound Xueshuantong capsule is effective in the treatment of glaucomatous optic atrophy , can improve the ocular hemodynamics and improve the visual function.
