PLL, or Primary Lens Luxation, is a hereditary eye condition that affects some dog breeds. In dogs with PLL, the ligaments holding the lens in place within the eye become weak, which can cause the lens to become partially or completely dislocated from its normal position. This dislocation can lead to serious complications, such as glaucoma (increased pressure within the eye) and vision loss.
To minimize the risk of PLL in future generations, we perform genetic testing with Embark for PLL and avoid breeding those that are carriers or affected by the condition.
- Cloudy or hazy appearance in the eye: This can be due to the dislocated lens, or it may indicate the development of cataracts or secondary glaucoma.
- Redness and inflammation: The eye may appear red and swollen, which can be a sign of increased pressure within the eye (glaucoma) or other complications.
- Squinting or eye pain: Dogs with PLL may squint, blink excessively, or show signs of discomfort, such as pawing at the eye or rubbing it against surfaces.
- Changes in vision: Partial or complete lens dislocation can cause blurry or reduced vision. Dogs may have difficulty navigating their environment, bump into objects, or seem hesitant to jump or climb.
- Sudden onset of acute glaucoma: In some cases, the dislocated lens can block the eye’s normal fluid drainage, causing a rapid increase in intraocular pressure. This can lead to severe pain, a dilated pupil that doesn’t respond to light, and a significant risk of permanent vision loss.
