What is KP in Eye?

KP in the eye refers to keratic precipitates, which are cellular deposits found on the inner surface of the cornea.

Understanding Keratic Precipitates (KPs)

KPs are a key indicator of inflammation inside the eye (intraocular inflammation). These deposits are essentially collections of cells that adhere to the corneal endothelium, the innermost layer of the cornea.

Composition of KPs

According to the reference, KPs are typically composed of:

• Epithelioid cells
• Lymphocytes
• Polymorphonuclear cells

These cells are part of the body's immune response and their presence on the corneal endothelium indicates that the immune system is active in the eye.

Significance of KPs

• Diagnostic Tool: The presence, size, and distribution of KPs can help ophthalmologists diagnose various types of intraocular inflammation such as uveitis.
• Monitoring: Changes in KPs over time can indicate whether the inflammation is improving or worsening.
• Underlying Conditions: KPs are a sign of underlying inflammatory conditions, which need to be addressed with appropriate treatment.

Visual Representation of KPs

While not always visible to the naked eye, KPs can be observed during an eye examination using a slit lamp, which is a specialized microscope used by eye doctors. KPs appear as small, often white or pigmented, deposits on the back of the cornea.

Clinical Relevance

• KPs are not a disease in themselves, but rather a sign of other conditions.
• Treatment focuses on addressing the underlying cause of the inflammation.
• Early detection and treatment are essential to prevent damage to the eye.

In summary, keratic precipitates are a diagnostic marker for various inflammatory conditions within the eye and their presence warrants a thorough investigation and appropriate management.
