Lens Luxation in Dogs
Lens Luxation is a high-severity eye condition that can affect dogs of all ages and breeds. Lens luxation is displacement of the lens from its normal position due to breakdown of the suspensory ligaments (zonules). Primary lens luxation is hereditary. A luxated lens can cause acute glaucoma and retinal detachment. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 3-8 years. Early signs to watch for include sudden eye pain, visible lens displacement, watery eye, and corneal oedema. When treatment is required, costs are estimated at £1,500-£3,500 depending on severity, location, and the specific intervention needed. Lens Luxation has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
Signs & Symptoms
The following symptoms are commonly associated with Lens Luxation in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.
- Sudden eye pain
- Visible lens displacement
- Watery eye
- Corneal oedema
- Vision loss
Treatment Overview
Surgical removal of the luxated lens (intracapsular extraction) is the treatment of choice. Medical management with miotics helps when surgery is not immediately possible. Glaucoma treatment may also be required.
Typical onset: 3-8 years
Prevention & Screening
While not all cases of Lens Luxation can be prevented, the following steps reduce risk or enable earlier intervention:
- DNA test available (ADAMTS17 mutation) — do not breed affected dogs
- Annual eye examinations
Estimated Treatment Cost
Treatment for Lens Luxation is estimated at £1,500-£3,500, depending on severity, the specific intervention required, and your location. Costs may be higher for surgical procedures or ongoing management. Comprehensive pet insurance covering hereditary conditions is strongly recommended.
