Once the retina has partially detached, a shadow or curtain will come from the top or side of the eye until all vision is lost. During stage 5, the retina will completely detach and complete vision loss can be gradual or instantaneous.. Janelle . Fassbender. , MD, PhD. University of Louisville.

It contains visual receptors of the eye. The retinal neurons transmit the picture through the optic nerve fibers to brain for perception. DIFFERENT INVESTIGATION IN SPECIALTY CLINIC.

Adrenal glands can be affected by a variety of lesions. Adrenal lesions can either be primary, of adrenal origin, or secondary to other pathologies. Primary adrenal lesions can further be either of cortical or medullary origin. Functioning adrenal lesions can also give clues to the histologic diagnosis and direct workup. Over the years, various imaging techniques have been developed that have increased diagnostic accuracy and helped in better characterization of adrenal lesions non-invasively. In the first part of the two part series, we review adrenal imaging techniques and adrenal cortical tumors such as adenomas, adrenocortical tumors, adrenal hyperplasia and oncocytomas. First neuron.
