An unusual spot

The retinal pigment epithelium (RPE) is the pigmented cell layer just outside the neurosensory retina that nourishes retinal visual cells, and is attached to the choroid beneath and the retina above.   The 7 functions of the RPE are:    1.   light absorption essential   2.   epithelial transport   3.   spatial buffering of ions.   4.  visual cycle.   5.  phagocytosis of photoreceptor outer segments   6.  secretion  7.   immunologic privilege of the eye.    These functions are essential for good eye health and vision.   Retinal conditions such as macular degeneration and retinitis pigmentosa, affect the RPE.


This patient had a slight disruption in the RPE, which had minimal effect on the vision.
