Treatment of canine periocular dermatitis with rhytidectomy (surgical face-lift) and fluorescence photobiomodulation: A case report.

Canine periocular dermatitis may be associated with excessive facial folds and heavy brows (EFF-HB). There is no gold standard therapy for EFF-HB-associated periocular dermatitis, and conventional medical management may fail. Herein, we describe periocular fluorescence photobiomodulation and rhytidectomy as novel approaches to treat EFF-HB-associated periocular dermatitis refractory to medical management.

La dermatite périoculaire canine peut être associée à des plis faciaux prononcés et à des sourcils épais (EFF-HB). Il n'y a pas de traitement de référence de la dermatite périoculaire associée à l'EFF-HB, et la prise en charge médicale conventionnelle peut échouer. Ici, nous décrivons la photobiomodulation par fluorescence périoculaire et la rhytidectomie comme de nouvelles approches pour traiter la dermatite périoculaire associée à l'EFF-HB réfractaire à la prise en charge médicale.

La dermatitis periocular canina puede estar asociada con pliegues faciales excesivos y cejas densas (EFF-HB). No existe una terapia estándar para la dermatitis periocular asociada a EFF-HB, y el tratamiento médico convencional puede fallar. En este artículo describimos el uso de fotobiomodulación periocular de fluorescencia y ritidectomía como nuevas terapias para tratar la dermatitis periocular asociada a EFF-HB refractaria al tratamiento médico habitual.

A dermatite periocular canina pode estar associada a dobras faciais excessivas e sobrancelhas pesadas (EFF-HB). Não há nenhuma terapia de padrão ouro para dermatite periocular associada a EFF-HB, e os tratamentos clínicos convencionais podem falhar. Neste trabalho, nós descrevemos a fotobiomodulação fluorescente periocular e a retidectomia como novas abordagens para o tratamento de dermatite periocular associada a EFF-HB refratária ao tratamento medicamentoso.

Delayed periocular dermatitis as a rare side-effect of topical anti-glaucoma eyedrop instillation in two Shih-Tzu dogs with atopic dermatitis.

Two Shih-Tzu dogs with atopic dermatitis presented with delayed periocular dermatitis (PD) following the instillation of dorzolamide and dorzolamide/timolol combination eyedrops; the development of dermatologic signs took 94 and 104 d in cases 1 and 2, respectively. Hypersensitivity to anti-glaucoma eyedrops was highly suspected, and treatment was discontinued. Delayed PD was significantly relieved in cases 1 and 2, at days 155 and 64 after discontinuation, respectively. In this study, the clinical characteristics and progression of delayed PD were described to inform clinicians who may encounter this rare side effect.

Clinical findings and outcomes for dogs with uveodermatologic syndrome.

OBJECTIVE To evaluate signalment, clinical signs, treatment, and factors affecting visual prognosis in dogs with uveodermatologic syndrome (UDS). DESIGN Retrospective case series and nested cohort study. ANIMALS 50 dogs (37 Akitas and 13 non-Akitas) with UDS evaluated at 4 ophthalmology practices. PROCEDURES Data were collected from the medical records regarding signalment, clinical signs, biopsy results, medications, adverse effects, vision and glaucoma status at initial and subsequent examinations, and duration of follow-up. Various factors were examined for associations with development of blindness or glaucoma following initial examination. RESULTS The most common ophthalmic signs included aqueous flare (n = 35 [70%]), iris abnormalities (29 [58%]), retinal detachment (23 [46%]), and choroidal depigmentation or chorioretinal infiltrates (10 [20%]). At initial examination, 36% (18/50) of dogs had glaucoma and 57% (26/46) were blind in both eyes. Twenty-five (50%) dogs had vision at their final visit, representing 78% of the 32 dogs that had vision at initial examination or regained vision during the follow-up period. In dogs that lost vision, median time to permanent blindness in both eyes was 13.5 months (range, 0.4 to 59 months) after initial examination. No significant associations with time to glaucoma or vision loss were identified for signalment variables, specific medications, or duration of clinical signs prior to initial examination. CONCLUSIONS AND CLINICAL RELEVANCE UDS commonly resulted in glaucoma, vision loss, or both in affected dogs. No evaluated factor was associated with visual prognosis; however, a subset of patients maintained vision through to the final recheck examination.

Dermatitis and lymphadenitis resembling juvenile cellulitis in a four-year-old dog.

A four-year-old, entire male toy poodle was presented with a two-and-a-half-week history of ocular discharge progressing to periorbital alopecia, depigmentation, alopecia and ulceration around the muzzle. There was also a haemorrhagic discharge from the ears, pyrexia, lethargy and generalised lymphadenopathy. The clinical, cytological, bacteriological and histopathological findings were consistent with a diagnosis of dermatitis resembling juvenile cellulitis in an adult dog. Glucocorticoid therapy led to rapid resolution of the clinical signs and the dog has remained in remission for two years after cessation of treatment.

The histological lesions of Trichophyton mentagrophytes var erinacei infection in dogs.

A retrospective study of the histological features of four cases of canine Trichophyton mentagrophytes var erinacei infection is reported. In all four dogs the initial lesions affected the dorsal muzzle and in two dogs the lesions spread to more distant sites on the body. Clinically, the lesions were characterized by scaling, crusting and hair loss. Histologically, the main lesions were characterized by acanthosis, epidermal, ostial and infundibular hyperkeratosis, serocellular crusting, mural folliculitis and furunculosis. Fungal hyphae were usually sparse and often difficult to see in haematoxylin and eosin stained sections. When visible they were seen in the epidermal, ostial and infundibular scale and, less frequently, within hair shafts.

Surgical correction of periocular fat pad hypertrophy in pot-bellied pigs.

OBJECTIVE: To report surgical correction of hypertrophic periocular fat pads that cause loss of vision and behavioral changes in pot-bellied pigs. STUDY DESIGN: A retrospective study. ANIMALS OR SAMPLE POPULATION: Nine Vietnamese pot-bellied pigs. METHODS: Medical records of nine pot-bellied pigs admitted between 1994 and 1997 for loss of vision associated with hypertrophied periocular fat accumulations were reviewed. Outcome was assessed by contacting owners 4 months to 5 years after surgery. RESULTS: The most common clinical signs were related to impaired vision and included periocular dermatitis, lethargy, and aggressive behavior. Surgical removal of redundant periorbital fat and skin resulted in marked improvement in vision and behavior in all pigs. Overall client satisfaction was excellent.
