Vasoproliferative tumour

This is a rare, benign tumour consisting of tiny, abnormal blood vessels. It can occur in isolation or may be association with conditions such as retinitis pigmentosa, inflammation and ocular injury. 

 

Vasoproliferative tumours tend to leak fluid and fatty exudates into the retina, which can become detached.

Loss of vision can occur if the macula is affected by exudates or a cellophane membrane.

 

Some vasoproliferative tumours may remain dormant and asymptomatic for many years.

A variety of methods may be used. The following are listed in order of increasing invasiveness/morbidity:

  • Intraocular anti-VEGF agents
  • Cryotherapy
  • Plaque radiotherapy

 

Many patients require surgical treatment of vitreoretinal traction and cellophane maculopathy.
