Electroretinographic changes after intravenous lipid emulsion therapy in a dog and a foal with ivermectin toxicosis.

This case report describes ivermectin-induced blindness in a dog and a foal with normal ophthalmic fundic examinations and attenuated electroretinography (ERG). Subsequent recovery in ERG was noted following intravenous lipid emulsion (ILE) therapy. A dog and a foal were evaluated for ivermectin-induced blindness.

The effects of intravenous romifidine on intraocular pressure in clinically normal horses and horses with incidental ophthalmic findings.

Design: Original study.

Objective: To evaluate the effect of sedation with romifidine hydrochloride 1% (Sedivet: Boehringer-Ingelheim) on intraocular pressure (IOP) in the normal horse and horses with incidental ophthalmic findings as measured by applanation tonometry.

Animals: Nineteen clinically normal horses (13 geldings, six mares) and eight horses (three geldings, five mares) with incidental ophthalmic findings were included in this study.

Suspected systemic calcinosis and calciphylaxis in 5 horses.

Five horses were presented with signs of myopathy along with systemic malaise, hyperfibrinogenemia, hyperphosphatemia, and an elevated calcium phosphorus product (Ca*P). Postmortem findings were consistent with systemic calcinosis, a syndrome of calcium deposition in the tissue of organs including lungs, kidneys, muscle, and heart that has not been previously described in horses.

Comparison of survival rates for geriatric horses versus nongeriatric horses following exploratory celiotomy for colic.

Objective: To determine how survival rates in geriatric horses (>or= 20 years old) undergoing abdominal exploratory surgery for colic compare with survival rates for younger (nongeriatric) horses.

Design: Retrospective case-control study.

Animals: 56 geriatric horses and 487 nongeriatric horses undergoing exploratory celiotomy for colic.

Effect of omentectomy on adhesion formation in horses.

Objective: To determine if omentectomy would decrease the frequency of postoperative intraabdominal adhesions.

Study Design: Retrospective study.

Animals Or Sample Population: 44 horses that had either two ventral median celiotomies or a ventral median celiotomy and a necropsy more than 4 days later; 19 of these horses had their omentum removed at the initial surgery.
