Although VSS has received more attention in...
Uveitis-Glaucoma-Hyphema Syndrome Explained
Uveitis-Glaucoma-Hyphema (UGH) syndrome is a complex and potentially blinding ocular condition that usually develops as a complication of cataract surgery, particularly after the implantation of an intraocular lens (IOL). UGH syndrome, first described by Dr. Robert Ellingson in 1978, is characterized by three symptoms: uveitis (uveal inflammation), glaucoma (increased intraocular pressure), and hyphema. Mechanical irritation or malposition of the...
Uveitis: Comprehensive Insights into the Condition
What is uveitis? Uveitis is a broad term for inflammation of the uveal tract of the eye, which includes the iris, ciliary body, and choroid.

Uveal Melanoma: Detailed Insights and Information
What is uveal melanoma? Uveal melanoma is the most common primary intraocular malignancy in adults, and it develops from melanocytes in the uveal tract of the eye. The uveal tract, which includes the iris, ciliary body, and choroid, is the middle vascular layer of the eye and is responsible for supplying blood to the retina and other structures. Uveal melanoma...
Comprehensive Overview of Uveal Effusion Syndrome
Uveal Effusion Syndrome (UES) is a rare and complicated ocular condition characterized by the accumulation of fluid in the uveal tract, which includes the iris, ciliary body, and choroid.

Trichiasis: How to Recognize and Manage It
Trichiasis is an ocular condition characterized by misaligned eyelashes that grow inward toward the eye rather than outward. This abnormal growth causes the lashes to come into direct contact with the cornea, conjunctiva, or both, causing significant discomfort, irritation, and potential damage to the eye's surface. Trichiasis can affect any part of the eyelid, but it is most often...
Exploring the Effects of Traumatic Vitreous Hemorrhage
Traumatic vitreous hemorrhage is characterized by the presence of blood in the vitreous humor, which is a clear, gel-like substance that fills the space between the eye's lens and retina. This hemorrhage occurs as a direct result of ocular trauma, which can range from blunt force injuries to deep wounds. The vitreous body is normally avascular, meaning it lacks...
Exploring the Impact of Traumatic Uveitis
Traumatic uveitis is a type of uveitis—a condition marked by inflammation of the uveal tract—caused solely by ocular trauma. The primary structures of the uveal tract are the iris, ciliary body, and choroid.
