Abstract Details

PURPOSE:We present a

Setting:

Tertiary referral centre

Methods:

We performed a 36 month retrospective review of the contralateral eye in 100 patents presenting with diabetic vitreous haemorrhage. We assessed the risk factors for new diabetic haemorrhage, assessing Age, Sex, Type of Diabetes, HBA1C%, Mean Arterial Blood pressure (MAP) and pseudophakia. Risk of new bleed was assessed using Kaplan Meyer cumulative hazard function.

Results:

The 36 month risk of vitreous haemorrhage in the second eye was 60%. Pseudophakia reduced the risk by 93% / month (p=0.01). Hypertension increased the risk by 4% / month (P=0.05). Age, type of diabetes and HBA1c% all had non-significant impact on risk of vitreous haemorrhage.

Conclusions:

Pseudophakia reduced the risk of vitreous haemorrhage more that all other variables. Reasons for this are discussed. This is a new finding and runs against the current literature which suggests that cataract surgery accelerated diabetic retinopathy. Control of blood pressure is important in preventing complications of diabetes and this is again bourn out in end stage diabetic retinopathy.
