Equine recurrent uveitis (ERU) – also known as moon blindness, recurrent iridocyclitis, or periodic ophthalmia [1] – is an acute, nongranulomatous inflammation of the uveal tract of the eye, occurring commonly in horses of all breeds, worldwide. The causative factor is not known, but several pathogeneses have been suggested.
Cool, wet compresses over the eyes and artificial tears may help local symptoms when the feeling returns. Nonsteroidal anti-inflammatory drug (NSAID) eyedrops are widely used to lessen inflammation and eye pain, but have not been proven in rigorous trials. Systemic (oral) pain medication is given if discomfort is severe.
Mild conjunctivochalasis can be asymptomatic and in such cases does not require treatment. Lubricating eye drops may be tried but are often ineffective. [8] If discomfort persists after standard dry eye treatment and anti-inflammatory therapy, surgery may be undertaken to remove the conjunctival folds and restore a smooth tear film.
The management of strabismus may include the use of drugs or surgery to correct the strabismus. Agents used include paralytic agents such as botox used on extraocular muscles , [ 1 ] topical autonomic nervous system agents to alter the refractive index in the eyes, and agents that act in the central nervous system to correct amblyopia.
Botulinum toxin therapy of strabismus is a medical technique used sometimes in the management of strabismus, in which botulinum toxin is injected into selected extraocular muscles in order to reduce the misalignment of the eyes. The injection of the toxin to treat strabismus, reported upon in 1981, is considered to be the first ever use of ...
This is when it is said to be "compensated". When fusional reserve is used to compensate for heterophoria, it is known as compensating vergence. In severe cases, when the heterophoria is not overcome by fusional vergence, sign and symptoms appear. This is called decompensated heterophoria. Heterophoria may lead to squint, also known as strabismus.
Horses naturally open their mouths to relieve the pain when a bit – a metal bar placed over the tongue – causes too much pressure, experts say. But dressage competitors lose points if their ...
If chemosis has occurred due to excessive rubbing of the eye, the first aid to be given is a cold water wash for eyes. [citation needed] Other causes of chemosis include: Superior vena cava obstruction, accompanied by facial oedema; Hyperthyroidism, associated with exophthalmos, periorbital puffiness, lid retraction, and lid lag
