What is crystalline or chalky white corneal opacity primarily associated with?

• A. Mineral or lipid deposits
• B. Viral infections
• C. Uveitis
• D. Corneal ulcers

Answer: (A)

The presence of crystalline or chalky white corneal opacity is primarily indicative of mineral or lipid deposits within the corneal stroma. These deposits can be a result of a variety of conditions, such as metabolic disorders that cause abnormal levels of substances like calcium or cholesterol in the body. When such deposits occur, they can be seen as a distinct, opaque appearance on the cornea, altering its transparency and potentially affecting vision. This type of corneal opacity is often associated with conditions like lipid keratopathy or corneal mineralization, which can develop independently of infectious or inflammatory processes. In contrast, viral infections, uveitis, and corneal ulcers typically lead to different types of corneal changes, such as edema, scarring, or pigmentation, rather than the crystalline or chalky appearance that is characteristic of mineral or lipid deposits. Understanding the specific nature of corneal opacities is essential for accurate diagnosis and proper treatment in veterinary ophthalmology.
