[Vitrectomy for proliferative diabetic retinopathy associated with iris rubeosis].
OBJECTIVE
To compare the results of vitrectomy for phakic cases and those of aphakic cases with proliferative diabetic retinopathy (PDR) accompanied by rubeosis iridis.


METHODS
We reviewed 34 eyes of 24 cases that underwent vitrectomy for proliferative diabetic retinopathy with rubeosis iridis.


RESULTS
Phakic eyes needed significantly more reoperations (p < 0.001) than aphakic eyes. Aphakic eyes had significantly more successful visual results (p < 0.05) and better control of intraocular pressure (p < 0.005) than phakic eyes.


CONCLUSIONS
This study showed the possibility that phakic eyes had more ischemic retina producing more angiogenic factors than aphakic eyes which had the same grade of rubeosis iridis. Phakic eyes with pre-operative rubeosis iridis need thorough clearance of ocular ischemia by panretinal photocoagulation.
