What are the common causes of deep vascularization in the cornea?

• A. Corneal ulcers and cataracts
• B. Uveitis and deep corneal ulceration
• C. Conjunctivitis and keratitis
• D. Allergic reactions and pterygium

Answer: (B)

Deep vascularization in the cornea commonly indicates underlying inflammatory conditions that can significantly impact the health and clarity of the corneal tissue. Uveitis, which is inflammation of the uveal tract of the eye, can lead to corneal changes as a consequence of ongoing inflammation and increased vascular response. When uveitis occurs, it can cause significant discomfort and damage to the surrounding ocular structures, leading to processes such as neovascularization in the cornea, where new blood vessels form as a response to chronic irritation or hypoxia. Deep corneal ulceration is another critical factor that can result in deep vascularization. When the cornea is ulcerated, it can activate various healing mechanisms in the eye, leading to the proliferation of blood vessels into the previously avascular cornea. This neovascularization is a hallmark response to the loss of corneal integrity and can result in clouding and impaired vision if left untreated. In contrast, while corneal ulcers are noted in other answer choices, they often do not specify the depth of the ulceration and the associated vascular changes. Other listed conditions, such as conjunctivitis, keratitis, allergic reactions, and pterygium, tend to cause superficial changes rather than deep vascularization, making them less
