Keratitis in Leopard Geckos: Cloudy, Painful, Inflamed Corneas

Keratitis means inflammation of the cornea, the clear outer layer at the front of the eye. In leopard geckos, that inflammation can make the eye look cloudy, bluish, dull, or uneven. It is often painful, even when the change looks mild from the outside.

Keratitis is not one single disease. It is a description of what the cornea is doing in response to irritation, injury, infection, dryness, or nutritional problems. In reptiles, eye disease is often tied to husbandry, especially retained shed, debris, low humidity during sheds, and vitamin imbalances.

Some cases are superficial and improve with prompt care. Others involve corneal ulcers, deeper infection, or scarring that can threaten vision and the eye itself. Because leopard geckos may hide illness until they are uncomfortable, a cloudy eye or repeated squinting deserves timely veterinary attention.

Leopard geckos usually develop keratitis because the cornea has been irritated or damaged. Common causes include retained shed around the eye, scratches from loose substrate or enclosure debris, feeder insect bites, rubbing at the eye, and poor enclosure sanitation. Once the cornea is irritated, bacteria can take advantage of the damaged surface and make inflammation worse.

Nutrition also matters. Reptiles with low vitamin A intake can develop abnormal changes in the tissues lining the eyes and tear ducts, which raises the risk of eye inflammation and secondary infection. This is one reason your vet may ask detailed questions about gut-loading, supplement rotation, and exactly which vitamins are being used.

Environmental stress can add to the problem. Inadequate humidity during sheds, improper temperatures, dehydration, and chronic low-level irritation from dusty substrates can all interfere with normal eye health. Sometimes keratitis is part of a bigger picture, such as stomatitis, respiratory disease, or generalized poor body condition, so your vet may recommend looking beyond the eye alone.

Your vet will start with a full history and physical exam, then perform a careful eye exam. That usually includes checking the eyelids, conjunctiva, corneal clarity, discharge, and whether retained shed or debris is trapped around the eye. In reptiles, even a basic husbandry review is part of diagnosis because lighting, humidity, substrate, diet, and supplements often contribute directly to eye disease.

If the cornea looks damaged, your vet may use fluorescein stain to look for an ulcer or scratch. This dye highlights defects in the corneal surface. Depending on what they see, they may also collect cytology or culture samples before medication is started, especially if infection is suspected or the eye is not responding as expected.

Some leopard geckos need gentle restraint, topical anesthetic, or sedation for a complete exam. In more involved cases, your vet may recommend bloodwork, imaging, or testing for underlying illness. The goal is not only to confirm keratitis, but to identify why it happened so treatment can match the cause.

Prevention starts with husbandry. Keep the enclosure clean, avoid dusty or abrasive substrate, and make sure your leopard gecko has an appropriate humid hide so sheds come off cleanly. Retained shed around the face and eyes should never be pulled off dry at home. If it does not loosen with safe humidity support, your vet should remove it.

Diet and supplementation are also important. Feed appropriately sized, gut-loaded insects and use a reptile supplement plan your vet is comfortable with. Vitamin A deficiency can contribute to eye and epithelial problems in reptiles, but too much vitamin A can also be harmful, so this is an area where targeted veterinary guidance matters.

Check your gecko's eyes during routine handling and feeding. Early signs like mild cloudiness, squinting, or discharge are easier to treat than a deep ulcer or scarred cornea. Prompt veterinary care, especially after a bad shed or eye injury, gives the best chance of preserving comfort and vision.
