What is often the result of untreated blepharitis?

Untreated blepharitis can lead to significant complications, with corneal disease or deterioration being a primary concern. When the eyelid margins are inflamed, it can result in inadequate lubrication of the eye surface, leading to chronic irritation. Over time, this irritation may progress, contributing to various corneal issues such as keratitis or corneal ulcers. These conditions can severely impair vision and overall eye health.

Additionally, while progressive dry eye symptoms can occur as a result of blepharitis, they are a consequence of the condition rather than a direct result of its treatment or its absence, as the underlying inflammation affects the meibomian glands responsible for producing the oily layer of tears. Increased eye pressure is generally not a direct result of blepharitis but can arise from other eye conditions. Thus, highlighting corneal disease as a consequence of untreated blepharitis emphasizes the critical need for appropriate management of this condition to preserve ocular health.
