Objective To describe and discuss ventromedial orbital lacrimal gland or duct cysts (dacryops) in dogs with extensive bone defects based on their symptoms, results of diagnostic imaging and histopathological examination, and therapy and discuss their potential origin based on the morphology. Animals studied Four dogs of different breeds, age, and sex were presented with a unilateral round, slow growing, indolent, and non‐tender process ventromedial to the nasal canthus of the eye. Procedures Transverse computed tomography showed a low‐density, non‐contrast‐enhancing cystic process ventromedial to the globe with extensive defects in the lacrimal and maxillary bones in all cases. The cystic character of the structure was confirmed by the aspiration of the brownish fluid without cellular and microbiological contents. For treatment, the cystic fluid was aspirated, and the sclerosing agent polidocanol was injected in three cases. Cystorhinostomy (nasal marsupialisation) was performed in one case as the first choice and in another case following failure of sclerotherapy. Histopathological examination of the cyst walls was performed in two cases and confirmed the diagnosis of dacryops. Results Follow‐up between 2 and 18 months showed no recurrence and very good to excellent cosmetic results. Conclusions Aberrant lacrimal gland or duct tissue with secondary development of dacryops should be included in the differential diagnoses of ventromedial orbital cysts. Large cysts near the lacrimal drainage system with extensive bone defects in dogs should be treated by nasal marsupialization. Treatments such as evacuation of the cyst and inducing sclerosis (sclerotherapy) should be reserved for exceptional cases.

“…The nasolacrimal system balances the amount of tear film on the surface of the eye by releasing tears and keeps the ocular surface healthy (11,22). The nasolacrimal drainage system consists of the nasal puncta, the canaliculi, the nasolacrimal sac and the nasolacrimal duct ending in the nasal vestibule (22). In dogs and cats, the nasolacrimal sac is poorly developed and slightly enlarged, surrounded by fossa sacci lacrimalis (22).…”

“…Surgical intervention of dacryocystitis, widely performed in veterinary medicine, is known as dacryocystotomy with an additional stent placement within the nasolacrimal duct to prevent its obstruction (6). Lacrimal rehabilitation, such as conjunctivorhinostomy, conjunctivobuccostomy, dacryocystomaxillorhinostomy or canaliculorhinostomy, can be additionally applied to facilitate tear drainage (8,22). However, in human medicine, dacryocystectomy, or the complete removal of the nasolacrimal sac, has been performed in certain conditions such as recurrent dacryocystitis, granulation tissue, or fibrotic sac, especially in elderly patients (1,4,5,16).…”

A 3-year-old spayed female beagle dog was presented with epiphora, severe hemorrhagic and purulent ocular discharge in the right eye (OD). A reflux of the discharge through the other canaliculi, associated with signs of chronic inflammation, was observed on cytology. Dacryocystorhinography revealed retention of contrast media ventral to the lower punctum, indicating complete obstruction and the potential presence of radiolucent foreign body. Ocular discharge subsided after the first treatment, including flushing of the nasolacrimal duct and application of topical antibiotics and corticosteroids, but clinical symptoms of the dacryocystitis waxed and waned thereafter. Surgical treatment was delayed for 8 months due to Dirofilaria immitis infection, and topical treatment and monthly flushing were maintained. On the day of operation, a foreign body was released through the fistula, while flushing for disinfection under general anesthesia, just before the surgery. Dacryocystectomy was performed to remove necrotic tissue and residual foreign body around the nasolacrimal cyst. Upon histopathologic findings, the removed foreign body was considered to be a plant, and the nasolacrimal cyst was comprised of chronic active ulcerative inflammation and necrotic tissues. At the 1-week recheck, improvement of epiphora and ocular discharge and healing of the surgical site was noted. In conclusion, nasolacrimal duct foreign body can be considered in recurrent dacryocystitis, despite nasolacrimal flushing and topical medication. In this study, dacryocystectomy was curative without recurrence of dacryocystitis or epiphora.

PurposeTo describe a novel technique of nasolacrimal foreign body extraction in dogs by using a 20G vitreoretinal forceps introduced through the superior lacrimal punctum.MethodsA retrospective review of the medical records of dogs with dacryocystitis due to nasolacrimal foreign bodies between the years 2001 and 2022 was performed. We recorded the breed, age, affected eye, type and number of foreign bodies, concomitant diseases, and the use of imaging techniques. All animals underwent the same procedure of a 20G vitreoretinal forceps insertion through the upper canaliculus reaching the lacrimal sac and retrograde extraction of the foreign bodies.ResultsA total of 28 dogs were included, 16 males and 12 females, with a mean (±SD) age of 4.7 (±3.2) years. The most common breeds were Wire‐Haired Dachshund (4/28; 14.29%) and Labrador Retriever (3/28; 10.71%). Additional imaging techniques were used, such as orbital ultrasound in 13 cases (13/28; 46.43%) and computed tomography in one case (1/28; 3.57%). The most common type of foreign body retrieved was grass awns, although seeds and plant debris were also found. Dacryocystitis resolved after removal of the foreign body and appropriate medical therapy was ensured in all cases in the 1‐month postprocedure follow‐up.ConclusionExtraction of nasolacrimal foreign bodies with vitreoretinal forceps is a novel, noninvasive, and easily applicable technique that, although not successful in all cases, can be attempted before performing more aggressive surgery.
