Tunica vasculosa could refer to any tunic rich in blood vessels.

Persistent tunica vasculosa lentis is a congenital ocular anomaly.

Tunica vasculosa can refer to:

The tunica vasculosa lentis is an extensive capillary network, spreading over the posterior and lateral surfaces of the lens of the eye.

The vascular tunic, also known as the tunica vasculosa oculi, is the middle vascularized layer which includes the iris, ciliary body, and choroid.

Occasionally, failure of the normal third trimester gestational atrophy of the hyaloid canal and the tunica vasculosa lentis is associated with other anomalies.

The tunica vasculosa is the vascular layer of the testis, consisting of a plexus of bloodvessels, held together by delicate areolar tissue.

By nine weeks into human development, the lens is surrounded and nourished by a net of vessels, the tunica vasculosa lentis, which is derived from the hyaloid artery.

In animal anatomy, tunica refers to a membranous structure lining a cavity, or covering an organ such as a gland or a blood vessel; types include Tunica albuginea (disambiguation) and Tunica vasculosa (disambiguation)

It is applied to the tunica vasculosa over the glandular substance of the testis, and, at its posterior border, is reflected into the interior of the gland, forming an incomplete vertical septum, called the mediastinum testis (corpus Highmori).

It can be present in three forms: purely anterior (persistent tunica vasculosa lentis and persistent posterior fetal fibrovascular sheath of the lens), purely posterior (falciform retinal septum and ablatio falcicormis congentia) and a combination of both.

Leukocoria is a medical sign for a number of conditions, including Coats disease, congenital cataract, corneal scarring, melanoma of the ciliary body, Norrie disease, ocular toxocariasis, persistence of the tunica vasculosa lentis (PFV/PHPV), retinoblastoma, and retrolental fibroplasia.
