What is drooping eyelid called?
Drooping of the eyelid is called ptosis. Ptosis may result from damage to the nerve that controls the muscles of the eyelid, problems with the muscle strength (as in myasthenia gravis), or from swelling of the lid.
What is the difference between entropion and trichiasis?
Trichiasis describes eyelashes which are mis-directed towards the eyeball, and should not be confused with entropion, in which the eyelid itself is rolled inwards. This is an important distinction, as the treatment for the two conditions is not the same.
What is the difference between ectropion and entropion?
Entropion is a condition in which the eyelid is turned inward (inverted), causing the eyelashes to rub against the eyeball. Ectropion is a condition in which the eyelid is turned outward (everted) so that its edge does not touch the eyeball.
When do you remove tarsorrhaphy?
Permanent tarsorrhaphy in the horse 5.6). Sutures are removed in 10–12 days, leaving the eyelid margins adhered. The tarsorrhaphy is left in place until the eyelids heal or neurologic function returns.
What is a lateral tarsorrhaphy?
Lateral tarsorrhaphy attempts to offset the upper lid retraction with the lower lid laxity. It involves suturing the free outer edge of the upper and lower eyelids together. After division of the eyelid anterior to the gray line, the mucocutaneous border of the lid margin is excised.
What is Pan Ophthalmitis?
Panophthalmitis is the inflammation of all coats of the animal eye including intraocular structures. It can be caused by infection, particularly from Pseudomonas species, such as Pseudomonas aeruginosa, Clostridium species, Whipple’s disease, and also fungi.

What is lateral canthotomy and cantholysis?
With lateral canthotomy and cantholysis, the lateral canthal tendons that attach the eyelids to the orbital rim are cut so that the pressure within the orbit can be released. This procedure is also performed on the medial canthal tendons (medial canthotomy and cantholysis).
What is canthotomy and how does it work?
What is Canthotomy? It’s a Medical surgery procedure done by an ophthalmologist surgeon who is specialised in oculoplastic, an operation for lengthening the palpebral fissure by an incision through the lateral canthus also for restoration of the canthus.
How do you do a lateral canthotomy with hemostat?
Apply hemostat to the lateral canthus from the angle of the eye to the orbital rim and clamp shut for ~1 min. (provides relative devascularization as well as a landmark for the canthotomy) Using scissors, incise the lateral canthus from the angle of the eyelid to the orbital rim (~1cm).
How do you prepare for A canthotomy?
Secondary indications (subjective and nonspecific) – if only secondary indications are present, get emergent ophthalmology consult prior to performing canthotomy. Prep and drape the area (Irrigation with normal saline is acceptable prep given emergent nature of procedure)
