vaeyemd Persistent #pupillary membrane (PPM) is a condition of the eye involving remnants of a fetal membrane that persist as strands of tissue crossing the pupil.

The pupillary membrane in mammals exists in the fetus as a source of #blood supply for the #lens. It normally #atrophies from the time of birth to the age of four to eight weeks.
PPM occurs when this atrophy is incomplete. It generally does not cause any symptoms but can reduce VA if severe.

The strands can connect to the cornea or lens, but most commonly to other parts of the iris. Attachment to the #cornea can cause small corneal opacities, while attachment to the lens can cause small #cataracts.
Using topical atropine to #dilate the pupil may help break down PPMs and only in #extreme cases will #surgery be required. .

PS: Apart from PPM what else can you #notice about this #eye??

amyleighhewitt Eye Physiology:

The is the organ that enables animals, such as this beautiful horse, to be able to see. Tissue layers behind the retina (back of the eye) principally absorb light or reflect it. Photoreception and light transduction occurs in the rods and cone receptors.

İster denizi hatırlatsın,
İster geceyi.
Bir sevgi dolu bakmayı bilmeli insanın gözleri.
Bir de hep gülmeli gözbebekleri...
