Complications associated with use of a one-hole subpalpebral lavage system in horses: 150 cases (1977-1996).

OBJECTIVE

To determine type and frequency of complications associated with use of a one-hole subpalpebral lavage (SPL) system in horses.

DESIGN

Retrospective study.

ANIMALS

150 horses with 156 SPL systems.

PROCEDURE

Signalment, primary complaint, method used for placement, time SPL system was in place, and complications were retrieved from medical records.

RESULTS

Complications were not associated with placement, maintenance, or removal of 66 of 156 (42%) SPL systems. A minor complication was reported in association with 53 (34%) SPL systems, and a serious complication was reported in association with 37 (24%). The 3 most common minor complications were mild swelling of the eyelid (31 horses), tearing of SPL system tubing (20), and loss of the injection cap (30). Serious complications included problems with the SPL system requiring its premature removal and possible replacement (26 horses), removal of the SPL system by the horse (6), infection of the eyelid (4), loss of the footplate in the eyelid (5), and cornea ulceration (1).

CLINICAL IMPLICATIONS

Proper attention to the size of the footplate and placement of the SPL system in the eyelid should decrease the risk of serious complications. Minor eyelid swelling should be expected in the first 48 hours after SPL system placement.
