Ectropion is a condition in which the eyelid turns outward away from the eye and the conjunctiva is often exposed to varying degrees, often in combination with incomplete lid closure, more commonly in the lower lid than in the upper lid. In the milder cases, the posterior lip of the lid margin leaves the eye, and in the more severe cases, the conjunctiva is exposed and the eyelid closure is incomplete. Ectropion can be classified as scarring, paralytic, senile, or spastic depending on the cause of the ectropion. Chronic conjunctivitis occurs when the conjunctiva is exposed for a long period of time, resulting in increased secretions and a dry, hypertrophic and congested conjunctiva. What is the definitive diagnosis of bilateral blepharospasm? 1. Spastic lid ectropion: bandages can be applied to restore the eyelid to its original position 2. Age-related lid ectropion: in mild cases, the lid should be wiped upward to reduce or prevent the ectropion from increasing. In severe cases, surgical correction is based on the principle of shortening the lid margin. The easiest way to correct this is to make a triangular excision in the conjunctival lid layer and a triangular excision in the muscular layer of the skin, which is then sutured together. Blepharoplasty can also be performed with a “Z” flap or a “V” or “Y” shaped flap. There are many surgical options for blepharoplasty, but the surgeon must choose the correct procedure based on the cause of the patient’s condition and operate closely to develop a personalized treatment plan. 3. Scarring blepharoplasty: Surgical treatment is required, with free implants being the most common method. 4. Paralytic lid ectropion: The key is to treat the facial palsy, using eye ointment, pulling the eyelid to protect the cornea and conjunctiva, or making temporary lid margin sutures. Depending on the cause of the ectropion, it is important to choose the appropriate surgical procedure. Post-operative dressing and antibacterial agents are required, and the time to remove the sutures varies depending on the procedure.
