Eyelid lacerations should be reapposed as soon as possible. Lacerations involving the lid margin require exact apposition to prevent longterm v-shape defects and an impaired lid function. Small dogs and cats require a single layer of sutures (usually single interrupted 4-0 silk sutures) while the large and giant breeds require 2-layer closure; the deep layer involves the tarsus and orbiculis oculi muscle (single interrupted 4-0 absorbable sutures) and the superficial layer (skin) apposed with simple interrupted 4-0 silk sutures (remove after 7–10 days). Horses require double-layer closure. When skin sutures are in place, the lid must be protected from self-trauma by either an Elizabethan collar (dogs and cats) or hard eye cup (horses). Postoperative therapy often includes topical antibiotics and corticosteroids, as well as systemic antibiotics and NSAID.
