Persistent tunica vasculosa lentis is a medical term used to describe a congenital condition that occurs in infants. It refers to the presence of blood vessels on the surface of the eye's lens that don't disappear as they should. This may not cause any problems in some cases, but in certain situations, it can lead to serious eye conditions, including cataracts and glaucoma. Some potential synonyms for this condition include persistent pupillary membrane, hyaloid artery remnant, and persistent fetal vasculature. It is important to note that all of these terms are describing the same condition and should be understood as such. Treatment may involve surgery, corrective lenses, or other medical interventions, depending on the specific situation.
