What is the primary symptom associated with ocular rosacea?

The primary symptom associated with ocular rosacea is redness, which often manifests as a persistent flushing on the face and around the eyes. Ocular rosacea can lead to symptoms such as redness of the eyelids, tear film instability, and inflammation of the surface of the eye, which may present as a burning or gritty sensation.

When considering ocular rosacea, it's essential to recognize that while symptoms like itching, lesions, and dryness can occur, the hallmark symptom is typically the redness that results from the increased blood flow to the facial area. This redness can be accompanied by other symptoms like flushing or irritation, but it is the redness that most distinctly characterizes the condition.

Therefore, understanding that redness is the primary and most defining symptom helps in diagnosing and managing ocular rosacea effectively.
