Five-Year Outcomes of Vitrectomy for Proliferative Diabetic Retinopathy

Yvonne Luo, Mr Lyndon Da Cruz

Objective: To evaluate the long-term (5-year) outcome and benefits of patients who underwent vitrectomy for complications associated with proliferative diabetic retinopathy.

Method: This is a retrospective case-note review of 50 patients who underwent vitrectomy +/- endolaser +/- delamination for proliferative diabetic retinopathy during the period of 2003 to 2005. All patients were under the care of one consultant (LDC). The main outcome measures are: (i) final visual acuity at the 5 years' follow-up; (ii) serious complications including endophthalmitis, development of rubeotic glaucoma, retinal detachment and recurrent vitreous haemorrhage; and (iii) any additional surgery during the 5-year follow-up period are also noted. For patients who were discharged back to their local units, communications with the local units are established to obtain the required information for the 5 year follow-up.

Result: Under data collection and analysis – will be ready by December 2010

Since the first description of benefits of vitrectomy in proliferative diabetic retinopathy in DRVS study over 25 years ago, there is very little data on the long term visual outcome and complications in these patient. This study will provide valuable perspective into the long term benefits and risks associated with vitrectomy in proliferative diabetic retinopathy and provide an understanding of the progression of the disease modified by vitrectomy.
