| description | AIM:To investigate the effect of intravitreal injection of anti-vascular endothelial growth factor(VEGF)on choroidal thickness and posterior ciliary artery blood flow in patients with wet age-related macular degeneration(ARMD). <p>METHODS:A total of 93 wet ARMD patients enrolled into the ophthalmology department in our hospital from September 2014 to December 2016 were selected into our study. The patients were treated with anti-VEGF vitreous injection for 3mo. The central retinal thickness(CRT), subfoveal choroidal thickness(SFCT), best corrected visual acuity(BCVA, LogMAR), choroidal neovascularization(CNV)and parameters of ciliary arterial blood flow \〖systolic peak flow velocity(PSV), end-diastolic blood flow velocity(EDV)and mean blood velocity(mV), resistance index(RI)/pulse index(PI)\〗 before treatment(T0), 1mo after treated(T1), 2mo after treated(T2), 3mo after treated(T3)were recorded and compared. All patients had been followed for 18mo, and side-effect were recorded. <p>RESULTS: All wet ARMD patients had successfully completed intravitreal anti-VEGF injection. Compared with before treatment, BCVA, CRT, SFCT, and CNV had gradually decreased(<i>F</i>=72.738, 32.333, 7.305 and 957.450, <i>P</i><0.05)after treatment. BCVA, CRT, SFCT and CNV: T3<T2<T1<T0(<i>P</i><0.05). There had no significant difference in PSV, EDV and mV before and after treatment(<i>F</i>=2.619, 1.942, 0.820, <i>P</i>>0.05). Compared with before treatment, RI index had gradually decreased(<i>F</i>=25.451, <i>P</i><0.05)and PI index had gradually increased(<i>F</i>=8.660, <i>P</i><0.05)after treatment. PI: T3>T2≈T1>T0; RI: T3≈T2<T1≈T0(≈ means approximately equal to). All patients were followed up for a period of 18 to 29mo. The BCVA of 93 patients was 0.26-0.42(mean 0.32±0.06). There were no serious complications such as cataract and retinal detachment. Three cases had subconjunctival hemorrhage, 1 eye intraocular pressure increased, 1 eye corneal edema, 2 eyes appearance of foreign body sensation, all given symptomatic treatment or self-improvement.<p>CONCLUSION: Intravitreal injection of anti-VEGF can effectively reduce choroidal thickness and increase ciliary posterior arterial perfusion, with a good long-term effect and less risk. |
