Tip #165

Analysis

The vitreous has fine hyperreflectivity consistent with a vitreous hemorrhage. There is a bright line on the surface of the retina. This is consistent with an epiretinal membrane and is causing the retina to be tented. Intraretinal fluid is also present.

This patient was diagnosed with proliferative retinopathy (video); they we also suspected to have talc retinopathy on the basis of fine peripheral crystals seen in the retina.

In this tip's accompanying 15 min. video, Dr. Sharma takes you through additional diagnostic imagery as well as:

  • Review the pathogenesis of talc retinopathy
  • Learn common causes of epiretinal membrane
  • Review things to consider if you see opacification of the retina
