Are Epicapsular stars rare?
Pure capsular opacities associated with persistent pupillary membranes or epicapsular stars are very rare. They are congenital in origin, do not affect vision and may be nonaxial.
What are Epicapsular stars?
Epicapsular stars are tiny, stellate, pigmented opacities on the anterior lens capsule. Persistent pupillary membranes are fine iris strands extending across the pupil to other areas of iris (type I) or to the lens (type II) as seen in this photo.
Where are Epicapsular stars located?
The epicapsular stars are remnants of the tunica vasculosalentis, a vascular network that surrounds the lens during embryogenesis. As the opacities were not dense, they had no effect on the visual function of the left eye.
What is Spherophakia?
Spherophakia is a rare congenital bilateral eye disorder, which presents with weak zonules around a smaller and more spherical crystalline lens with an increased anteroposterior thickness of the lens, and highly myopic eye.
What is a double pupil?
Having two working pupils in the same eye–meaning they each have their own sphincter muscles and are capable of operating independently of each other–is extremely rare but can happen. It’s called polycoria and is one of the rarest conditions in the world.
Does persistent pupillary membrane affect vision?
Persistent pupillary membranes is a congenital condition with remnants of the blood vessels to the fetal lens (tunica vasculosa lentis). In most patients, it does not affect vision, although it may lead to earlier development of cataract. .
Can corectopia be fixed?
Corectopia is the displacement of the eye’s pupil from its normal, central position. It may be associated with high myopia or ectopia lentis, among other conditions. Medical or surgical intervention may be indicated for the treatment of corectopia in some cases.
