AIM: To analyze the related factors and clinical therapeutic effect of retinal vein occlusion(RVO).

METHODS: The clinical data of 122 patients(124 eyes)with RVO were retrospectively analyzed, which including 12 eyes(9.7%)of ischemia type branch retinal vein occlusion in patients with ischemic, 6 eyes(4.8%)of ischemia type central retinal vein occlusion, 59 eyes(47.6%)of non-ischemia type central retinal vein occlusion, and 47 eyes(37.9%)of non-ischemia type central retinal vein occlusion. Among all the patients, the average age were 60.6±11.8 years old, there were 48 patients(39.3%)with hypertension, 10 patients(8.2%)with diabetes, 20 patients(16.4%)with more than one related diseases, and 37 patients(30.3%)with none relevant history. Among them, 68 patients were treated only by drug conservative treatment, 49 patients were treated with the help of laser, and only 1 patient was treated by the vitrectomy surgery.

RESULTS:Seventy-two eyes(58.1%)had obvious effects; 22 eyes(17.7%)were significantly effective; 15 eyes(12.1%)were invalid; and 15 eyes(12.1%)became even worse.

CONCLUSION: CRVO is formed by both the local and systemic pathogenic factors. Clinical therapy should be treated dialectically. And the complete diagnostic evaluation combined with fundus angiography should be conducted according to the fundus hemorrhage time, the involvement extent and location so that personalized treatment can be used to improve the patient's treatment effect.
