How can recurrence of uveitis in horses be prevented?

March 22, 2025

Uveitisuveitis is a common condition in horses, causing repeated inflammation of the eye. This disease can lead to vision loss if not treated effectively. It is essential to implement preventive strategies to minimize the risk of recurrence.

1. Protect the horse's eyes from UV rays

Horses suffering from uveitis are particularly sensitive to sunlight. Using a UV mask specially designed for horses can significantly reduce this sensitivity and prevent painful flare-ups.

Equidiva's Helios 90% UV protection mask: an effective solution

Enhanced UV protection: micro-perforated fabric blocking 90% of UV rays.
Maximum comfort: fleece-lined contact areas, integrated headband to prevent eye irritation.
Complete protection: removable neck warmer and ear flaps made of Lycra fabric.
Optimal safety: Velcro and buckle closure system ensuring excellent support.

2. Maintain a clean and healthy environment

Ensure that the stable and bedding are cleaned regularly to prevent irritation and secondary infections that could trigger an episode of uveitis.

3. Strictly follow veterinary treatments

Administer the medication prescribed by your veterinarian rigorously, whether it be eye drops, ointments, or oral medication, in order to reduce the risk of recurrence.

4. Closely monitor changes in eye health

Regular monitoring allows for the rapid detection of any deterioration or improvement in the situation, facilitating early intervention if necessary.

5. Ensure proper nutrition and hydration

A balanced diet and adequate hydration strengthen the horse's immune system and promote faster and more effective healing.

Size guide - Premium or Helios mask

Using a tape measure (or a piece of string that you will measure afterwards), measure around your horse's head as shown in the photo:

Mask size	Head circumference
XS - Shetland	84 cm
S - Pony	90 cm
M - Cob	94 cm
L - Full	100 cm
XL - XFull	110 cm

If your horse's head measurement falls between two sizes, we recommend choosing the larger of the two.

Size guide - Equivizor masks (Lightweight, Arso, Convalescence models)

For these masks, the main measurement is the width of your horse's forehead. To do this, you need to add together three measurements:

Start at the outer corner of one eye and measure upwards at a slight angle to the middle of the forehead (measurement A).
continue along the front of your horse(measurement B),
Finish the measurement by directing the line slightly downward to the outer corner of the other eye (measurement C). This way, you will measure the widest part of your horse's forehead.

Add these 3 measurements (A+B+C) to obtain the size of your horse's forehead.

IMPORTANT: Do not measure directly from one eye to the other, as this will likely result in an inaccurate measurement.

equivizor mask measurements

Mask size	Forehead size
XS - Shetland	7.5–8.7 inches
S - Pony	8.7–11.4 inches
M - Cob	11.5–13.5 inches
L - Full	13-14 inches
XL - XFull	15-17 inches

Size guide - Rambo mask

Take these 3 steps:

L (full)	75 cm	105 cm	27 cm

If your horse is between sizes, we recommend choosing the smaller size.
