Neovascular Membrane

Did you know that bleeding underneath your retina can cause devastating vision loss?  Choroidal neovascular membranes are new blood vessels that grow beneath the retina in an area called the choroid.   These membranes are associated with many serious eye diseases, most commonly wet age-related macular degeneration. CNVM are also found in patients with histoplasmosis, eye injury, and myopic macular degeneration.

CNVMUnfortunately, my answer to this patient was “no.”   This is wet macular degeneration that I had to send for Avastin treatment by a retinal specialist.

There are two basic types of macular degeneration: “wet” and “dry.” Approximately 10-15% of the cases of macular degeneration are the “wet” (exudative) type.

In the “wet” type of macular degeneration, abnormal blood vessels (known as choroidal neovascularization or CNV) grow under the retina and macula. These new blood vessels may then bleed and leak fluid, causing the macula to bulge or lift up from its normally flat position, thus distorting or destroying central vision. Under these circumstances, vision loss may be rapid and severe.
