What are corneal infiltrates a result of?

Corneal infiltrates are primarily associated with viral infections or toxic reactions to solutions. When the cornea becomes infiltrated, it typically signifies an immune response to an infection or a reaction to a foreign substance. Viral infections are known to incite an inflammatory response that can lead to the accumulation of immune cells in the cornea, marking the presence of infiltrates.

Toxic reactions to contact lens solutions can occur due to preservatives or other chemicals within the solution that irritate the cornea. This irritation can provoke an inflammatory response, resulting in infiltrates as the body attempts to manage the perceived threat.

Understanding the mechanisms behind corneal infiltrates is crucial because it helps in identifying and treating the underlying causes effectively. This knowledge is particularly valuable for practitioners in maintaining patient eye health and preventing complications associated with contact lens wear.

While improper fitting of contact lenses, corneal abrasions from foreign bodies, and use of expired lens solutions can lead to various issues with the eyes and corneal health, they are not the primary causes of corneal infiltrates. Incorrect fitting may cause discomfort or physiological changes, abrasions can lead to infection, and expired solutions pose a risk of contamination, but these are not directly linked to the immune response and inflammatory infiltrates associated with infections
