Peripheral Cystoid Degeneration
Typical peripheral cystoid degeneration, characterized by zones of microcysts in the farperipheral retina, is present in almost all adults over the age of 20 years. Although retinal holes may form in these areas, they rarely cause retinal detachment. Reticular peripheral cystoid degeneration is almost always located posterior to typical peripheral cystoid degeneration. It usually occurs in the inner retina and presents with a linear or reticular pattern that follows the retinal vessels. This form is found in approximately 20% of adults and may, in some instances, develop into reticular degenerative retinoschisis.
