- Abstract
This article aims at the presentation of ocular emergency in small animal veterinary surgery. Lens luxation is the displacement of the lens from its normal position in the eye, which caused by breaking its contact with the zonular fibres equatorially. Etiology is diverse. The most common are two types of dislocation - primary lens luxation (PLL), found mainly in terrier type breeds and secondary, caused by many factors, e.g. glaucoma, cataracts or trauma. In general, the lens can fall backwards, what is known as posterior luxation or it can fall forwards into the eye, what is known as anterior luxation. Anterior luxation, which is extremely painful, treated as an emergency, due to the possibility of sudden blindness resulting from rapidly progressing glaucoma. Symptoms, in the form of corneal edema, severe pain and the aphakic crescent, visible in the pupillary aperture, are quite characteristic and do not provide much diagnostic difficulty. Treatment depends on the form of dislocation. In the case of anterior dislocation, surgical methods are recommended, while in the case of posterior dislocation, pharmacological treatment with mydriatics is advised.
