However, it is still not completely understood how CSCR develops,1 and three theories have so far been presented: RPE dysfunction theory, choroid
dysfunction theory, and combined choroid
and RPE dysfunction theory.
The iris is continuous with the choroid
and is the colored portion of the eye that can be seen by others.
This means that if you look at a red-free image on an optomap you see the choroids
, while the green-free image allows you to see the retina.
Other sites are the nasopharynx, maxillary sinus, thyroid gland, soft tissues of the anterior cervical region, parotid gland, tonsil, oropharynx, larynx, orbit, and choroids
of the eye and eyelid.
They discovered evidence of proteins expressed by the SERPING1 gene and the choroids
layer--the vascular layer next to the retina--the two areas affected by AMD.
In these vessels, deterioration in the parameters was parallel to the exacerbation of degenerative lesions in the retina and choroid
of the eye.
