Diabetic vitreous errateage often clears in a few weeks. If pan retinal laser photocoagulation is not possible, or there is persistent non-clearing vitreous errateage, vitrectomy should be performed. Purpose: To assess the outcomes of one year follow up of patients who underwent pars plana vitrectomy for non- clearing diabetic vitreous haemorrhage.


Retrospective case note study, analysed notes of patients who underwent pars plana vitrectomy following persistent non-clearing vitreous errateage.


90 eyes of 78 patients underwent vitrectomy. IDDM (46%), NIDDM (54%). The mean age was 55yrs (range 25-85yrs), 43 males and 35 females. 84% had more than 2000 burns of previous pan of retinal photocoagulation. Duration of persistent vitreous errateage to surgery was 8.5 months (range: 2-15months). Early complications included branch (2%)and central retinal artery occlusion (1%) and iatrogenic breaks (3%). Late complications included cataract (22%), epiretinal membranes (3%)and cystoid macular oedema (1%). Visual outcome at one year follow up, 6% had poor visual outcomes, 5% had no change in vision and 89% eyes maintained improved good visual outcomes.

Take home message:

Pars plana vitrectomy is an effective surgery for persistent non-clearing vitreous haemorrhage in both type 1 and 2 Diabetes. It results in significant visual improvement in most cases.  Vitrectomy should be performed within 3 months of persistent vitreous haemorrhage for best results, since maculopathy and/or proliferative disease may progress unchecked, thus compromising the final visual result.
