Equine Eye Evaluation 2

Uveitis Primary: true [blank_start]autoimmune[blank_end] disease against the [blank_start]basement[blank_end] [blank_start]membrane[blank_end] proteins Secondary: trauma eg bled into the eye leading to chronic [blank_start]inflammation[blank_end], infection - [blank_start]antigen[blank_end] localised in the eye and cannot get rid of it due to immunopriveledge and immune response.

T/F: Uveitis once treated is no more likely to come back than in another horse without hx of uveitis

The most suitable treatment options for horses with uveitis (short-term)

Which are acceptable long-term treatments for Equine recurrent uveitis?

Keratitis is inflammation of the [blank_start]cornea[blank_end] The severity is dependent on the [blank_start]immune[blank_end] [blank_start]response[blank_end] Pathology restricted to the cornea but the depth can vary [blank_start]Superficial[blank_end] +/- [blank_start]stroma[blank_end] +/- [blank_start]basement[blank_end] [blank_start]membrane[blank_end]

T/F: just like in the dog you can remove cataracts in the horse

The normal tonometry of a horse eye is [blank_start]20[blank_end]-30mmHg

Glaucoma is a [blank_start]slow[blank_end] [blank_start]increase[blank_end] in pressure, [blank_start]harder[blank_end] to detect in the horse, there is stretching of the [blank_start]base[blank_end] [blank_start]membrane[blank_end]. A sign is [blank_start]stripes[blank_end] along the cornea. Treatment: Timodol/ dorzolamide to [blank_start]reduce IOP[blank_end] Fix underlying issue [blank_start]Enucleation[blank_end] commonly carried out

[blank_start]Hypopyon[blank_end]: Inflammatory cells (pus) in the eye [blank_start]Hyphaema[blank_end]: blood in the eye [blank_start]Epiphora[blank_end]: excess tearing [blank_start]Miosis[blank_end]: constricted pupil [blank_start]Mydriasis[blank_end]: enlarged pupil

Lepto is a common cause of uveitis and even after the horse has recovered they can become reinfected as the antigen remains in the eye. What is the best way to test for lepto as a cause of ERU?
