The objective of this prospective study was to investigate the success rate, practicality and complications of a new perilimbal pocket technique for the replacement of prolapsed nictitans gland in 30 dogs (44 eyes). A first incision was made in the bulbar conjunctiva, 2-3 mm from and parallel to the infero-nasal limbus, a second incision on the bulbar aspect of the nictitating membrane (NM), 2-3 mm parallel to the free edge. The gland was returned to its normal position by suturing the subconjunctival tissues of the NM to the episcleral tissues, using four to six interrupted horizontal mattress sutures. The English bulldog, Neapolitan mastiff, great dane and American cocker spaniel were commonly presented. Nictitans gland prolapse occurred prior to one year of age in 83.3 per cent of dogs, and unilaterally in 15 patients. The procedure was easy to perform, and had a 90.9 per cent success rate, with minimal complications. The median duration of follow-up, conducted by ophthalmic examination or telephone contact with the owners, was 21.5 months. Tear production and ocular health were not affected in 17 eyes with at least six months follow-up. There was a statistically significant increase between preoperative and postoperative Schirmer tear test-1 measurements.

The prognosis for clinical remission in horses with extraocular lymphoma is generally fair to good, as long as the affected tissues are completely excised, and there is no eyelid or cutaneous involvement. Horses diagnosed with the nodular form of extraocular lymphoma seem to have the best prognosis with complete excision.

Leptospirosis is a potential cause of ERU in Belgium. Testing both intraocular media is advised whenever possible. This article is protected by copyright. All rights reserved.

Duration of corneal anaesthesia following tetracaine instillation was established enabling a better use when performing diagnostic and therapeutic procedures. Comparison of tetracaine with other ocular anaesthetics needs to be published in the future.

Nematode worms were retrieved from the left eyes of two dogs presented for unilateral ocular discharge in Belgium. Morphological and molecular identification were performed and the parasites were identified as Thelazia callipaeda. The history suggested that the infection had been acquired in south‐western France and southern Italy where the disease has been observed regularly for the last 6 and 12 years, respectively. In these two regions, the disease is considered endemic and spreading. To the authors’ knowledge, this is the first case report of canine thelaziosis in Belgium.
