Abstract
Purpose: :
To clarify a good indication of intravitreal triamcinolone acetonide (IVTA) injection for central retinal vein occlusion (CRVO) patients.
Methods: :
Since April 2004, we evaluated background features, including age, gender, preoperative visual acuity, type of CRVO (hemorrhagic or venous stasis) and duration between visual deterioration and IVTA intervention, of nine consecutive CRVO cases who underwent 4mg of IVTA injection.
Results: :
Three of nine cases recovered their best corrected vision to 20/20. Two of these three cases required 3 injections to maintain their vision. These three cases are significantly younger than those who recovered their vision less than 20/20 (55±10 vs. 66±7 (y. o. ), P<0.05) and they were treated by IVTA injection significantly earlier after visual deterioration than the others (2±2 vs. 10±5 (month), P<0.05). Gender, preoperative visual acuity and type of CRVO did not influence excellent visual recovery.
Conclusions: :
IVTA injection for central retinal vein occlusion is more effective, when applied to younger–age patients, and performed at earlier intervention.
