简要总结

to evaluate the wall-to-lumen ratio (WLR) of retinal arterioles in hypertensive patients with retinal vein occlusion (RVO) before and after dexamethasone intravitreal implant 0.7 mg (DEX) compared to a matched control group of normal eyes in non-hypertensive subjects.

入选标准

  • ability to provide written informed consent and comply with study assessments for the full duration of the study;
  • age > 20 years;
  • decreased visual acuity as a result of clinically detectable ME associated with either CRVO or BRVO;
  • the duration of macular edema was required to be between 4 and 24 weeks for both CRVO and BRVO;
  • retinal thickness in the central subfield (as measured using optical coherence tomography) had to be > 350 µm in the study eye.

排除标准

  • the exclusion criteria were as follows: diabetes; previous intravitreal anti-VEGF therapy or intravitreal steroid therapy; previous photodynamic therapy or focal laser; active retinal or optic disc neovascularization; active or history of choroidal neovascularization; presence of rubeosis iridis; any active infection; glaucoma, current ocular hypertension, or a history of steroid-induced intraocular pressure (IOP) increase in either eye; or concurrent eye disease in the study eye that could compromise visual acuity (e.g., choroidal neovascularization, diabetic retinopathy, epiretinal membrane).

结局指标

主要结局

change of outer arteriolar diameter

时间窗: the primary endpoint was at 6 months

change of inner arteriolar diameter

时间窗: the primary endpoint was at 6 months

次要结局

  • Secondary outcome measures were as follows: adverse ocular events; mean change in visual acuity; and mean change in central macular thickness.(Outcomes were analyzed at 4 intermediate time points: 30, 60, 90, and 150 days.)
