NCT01030770

Brief Summary

This study will enrol patients with diabetes who have already elected to undergo pars plana vitrectomy (eye surgery) to remove persistent vitreous haemorrhage (a complication of severe diabetic eye disease in which blood fills the inner cavity of the eye, obscuring the vision and preventing treatment to stop the bleeding). Those in the treatment arm will have an intravitreal injection of ranibizumab (Lucentis) at the same dose used for the treatment of neovascular (wet) age-related macular degeneration (a disease that has some features in common with diabetic eye disease). It is hypothesised that this will promote clearance of the vitreous haemorrhage and that this, in turn, may mean that some patients do not need to proceed to vitrectomy.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults (male or female over 18) with Type 1 or Type 2 diabetes mellitus
  • Grade 2-4 fundus obscuring diabetic vitreous haemorrhage of at least 2 months duration prior to screening in the study eye.
  • Subjects who have elected to undergo a therapeutic pars plana vitrectomy to clear persistent diabetic vitreous haemorrhage
  • Best corrected visual acuity from 40 letters (using 4 metre ETDRS visual acuity score) to perception of light in the study eye
  • Patients able and willing to give written and witnessed informed consent.

You may not qualify if:

  • The presence of tractional retinal elevation in the study eye, as detected by B mode ocular ultrasound or fundus biomicroscopy.
  • Other (non-diabetic) cause of vitreous haemorrhage
  • Other (non-diabetic) retinal vasculopathy in the study eye
  • Subjects who were listed for vitrectomy for recurrent vitreous haemorrhage alone, and not for persistent vitreous haemorrhage
  • Subjects whose planned vitrectomy was to have been combined with cataract surgery
  • Prior vitrectomy in the study eye
  • Visual acuity worse than 6/96 in the non study eye
  • Aphakia in the study eye
  • Pregnant (urine dipstick confirmed) or lactating women (women of childbearing potential should be advised to use appropriate contraception for three months following eye injection
  • Those with systemic or ocular contraindications to ranibizumab therapy
  • Sickle cell disease. Those with sickle trait may be included if there is no evidence of retinopathy in the non study eye.
  • Patients who have had an intravitreal injection of any therapeutic agent in the study eye
  • Subjects with active concomitant disease in the study eye, including uveitis and infection
  • Subjects with inadequate pupil dilation in the study eye, or other cause of significantly impaired fundus view
  • Subjects with potentially visually significant cataract in the study eye
  • +5 more criteria
