Abbreviations: AVR, artery to vein ratio; CRAE, central retinal artery equivalent (μ); CRVE, central retinal vein equivalent (μ); IVT, intravitreal triamcinolone; STT, subtenon triamcinolone. Statistical analysis was calculated by analysis of independent samples t-test, data were expressed as mean±SD.
