A retinal detachment is a serious eye condition in which the retina detaches from the back of the eye. This may cause a patient to experience flashes of light, an increase in floaters and a shade or curtain coming over the vision. The retina can be reattached in a variety of ways and can restore vision or preserve vision if detected early.
Vitrectomy is the surgical removal of the vietreous gel from the eye. This may be done as part of a retinal detachment repair to give the ophthalmologist a better view, or to assist in the treatment and clearing of bleeding in the back of the eye.
If the eye contains extra amounts of protein called VEGF (vascular endothelial growth factor), it can cause abnormal blood vessels to leak fluid that builds up in the eye and leads to vision changes. Lucentis injections can improve vision and reduce swelling by preventing damaged bleed vessels from leaking.
Avastin also blocks the protein VEGF and can be used to treat several eye conditions:
- Age related macular degeneration
- Diabetic retinopathy
- Central retinal vein occlusion
