Primary Lens Luxation
Primary Lens Luxation (PLL) is a hereditary disorder where the lens of the eye dislocates due to breakdown of the zonular fibers, leading to pain and potential blindness.
Detailed Description
PLL occurs when the fibers holding the lens in place degenerate, allowing the lens to move from its normal position. This can cause secondary glaucoma, inflammation, and rapid vision loss if untreated. PLL is most often inherited and requires prompt veterinary attention.
Common Symptoms
- Sudden eye pain
- Redness
- Cloudy cornea
- Sudden vision loss
Management Options
- Emergency surgical intervention (lens removal)
- Medical management for secondary glaucoma
- Pain control
