Ectropion is a condition in which your eyelid turns outward. This months blog details what the signs and symptoms of ectropion are and how you or your loved one can best treat it.
Trichiasis is a very common eyelid abnormality in which eyelashes are misdirected towards the cornea and conjunctiva that results in irritation. Continuous rubbing of eyelashes against the globe produces a painful sensation and may damage the vision. The eyelid margins are typically in a normal position and just the eyelashes are misdirected. Trichiasis can be divided into focal (limited to a certain area) or diffuse (involving a larger area).
This ocular condition arises when the tarsal plate (from which eyelashes and glands originate) gets damaged resulting in an abnormal orientation of the eyelashes. Abnormally directed eyelashes may result from congenital conditions, trauma, or infections. The posterior movement of eyelashes towards the cornea poses a range of problems, from irritation to ulceration. The prognosis of trichiasis is good if immediate attention is paid with proper follow-up visits.
It can occur in all age groups however most commonly in adults. The eyelids can be misdirected due to multiple reasons which are described as follows:
The history and examination of suspected patients helps in devising a treatment strategy. It is critical to ask if there is any previous history of severe infections, trauma/burns, or travel to trachoma endemic countries.
After getting a proper history, the following signs and symptoms may be present on exam in trichiasis patients:
Treatment of trichiasis usually involves treating the underlying disease state e.g trachoma.
Correction of trichiasis stops the progression of visual loss and may improve the existing vision (by subsiding corneal irritation and damage). It should be evaluated and managed by your ophthalmologist.
