Abstract
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.

Abstract
Canine eyelid masses (tumors) should include the differential clinical diagnoses of neoplasia and blepharitis. They have many common clinical signs including tumor, alopecia, and hyperemia. Biopsy and histologic examination remains the most effective diagnostic test to establish a confirmed diagnosis and appropriate treatment. Neoplasms are typically benign (tarsal gland adenomas, melanocytomas, and so forth) with the exception of lymphosarcoma. Blepharitis is noted in 2 age groups including dogs aged less than 1.5 years and middle aged to older dogs. Most blepharitis cases will respond to specific therapy once an accurate diagnosis is established.

Shim J, Kim SA, Seo K, Kang S. Delayed periocular dermatitis as a rare side-effect of topical anti-glaucoma eyedrop instillation in two Shih-Tzu dogs with atopic dermatitis. J Vet Sci 2022; 24:e6. [PMID: 36560838 PMCID: PMC9899941 DOI: 10.4142/jvs.22101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 10/11/2022] [Accepted: 11/08/2022] [Indexed: 12/13/2022] Open
Abstract
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.

Abstract
BACKGROUND The genus Malassezia is comprised of a group of lipophilic yeasts that have evolved as skin commensals and opportunistic cutaneous pathogens of a variety of mammals and birds. OBJECTIVES The objective of this document is to provide the veterinary community and other interested parties with current information on the ecology, pathophysiology, diagnosis, treatment and prevention of skin diseases associated with Malassezia yeasts in dogs and cats. METHODS AND MATERIAL The authors served as a Guideline Panel (GP) and reviewed the literature available prior to October 2018. The GP prepared a detailed literature review and made recommendations on selected topics. The World Association of Veterinary Dermatology (WAVD) Clinical Consensus Guideline committee provided guidance and oversight for this process. The document was presented at two international meetings of veterinary dermatology societies and one international mycology workshop; it was made available for comment on the WAVD website for a period of six months. Comments were shared with the GP electronically and responses incorporated into the final document. CONCLUSIONS AND CLINICAL IMPORTANCE There has been a remarkable expansion of knowledge on Malassezia yeasts and their role in animal disease, particularly since the early 1990's. Malassezia dermatitis in dogs and cats has evolved from a disease of obscurity and controversy on its existence, to now being a routine diagnosis in general veterinary practice. Clinical signs are well recognised and diagnostic approaches are well developed. A range of topical and systemic therapies is known to be effective, especially when predisposing factors are identified and corrected.

[PMID: 31921915 PMCID: PMC6930880 DOI: 10.3389/fvets.2019.00457] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Accepted: 11/28/2019] [Indexed: 12/25/2022] Open
Abstract
The study aimed to determine the impact of drop size on tear film pharmacokinetics and assess important physiological parameters associated with ocular drug delivery in dogs. Two separate experiments were conducted in eight healthy Beagle dogs: (i) Instillation of one drop (35 μl) or two drops (70 μl) of 1% fluorescein solution in each eye followed by tear collections with capillary tubes from 0 to 180 min; (ii) Instillation of 10 to 100 μl of 0.1% fluorescein in each eye followed by external photography with blue excitation filter (to capture periocular spillage of fluorescein) and tear collections from 1 to 20 min (to capture tear turnover rate; TTR). Fluorescein concentrations were measured in tear samples with a fluorophotometer. The TTR was estimated based upon non-linear mixed-effects analysis of fluorescein decay curves. Tear film pharmacokinetics were not superior with instillation of two drops vs. one drop based on tear film concentrations, residual tear fluorescence, and area under the fluorescein-time curves (P ≥ 0.163). Reflex TTR varied from 20.2 to 30.5%/min and did not differ significantly (P = 0.935) among volumes instilled (10-100 μl). The volumetric capacity of the canine palpebral fissure (31.3 ± 8.9 μl) was positively correlated with the palpebral fissure length (P = 0.023). Excess solution was spilled over the periocular skin in a volume-dependent manner, predominantly in the lower eyelid, medial canthus and lateral canthus. In sum, a single drop is sufficient for topical administration in dogs. Any excess is lost predominantly by spillage over the periocular skin as well as accelerated nasolacrimal drainage.

Abstract
BACKGROUND Blepharitis is a common finding in many dogs with various skin diseases. OBJECTIVES To establish a definition for canine blepharitis versus periocular dermatitis (POD), to evaluate the clinical findings and underlying skin diseases of blepharitis, and to document the effects of blepharitis on tear production in dogs. ANIMALS One hundred and two privately owned dogs with clinical signs of blepharitis and a definitive diagnosis of skin disease. METHODS AND MATERIALS Prospective evaluation of clinical signs and underlying diseases in dogs with blepharitis alone compared to dogs with blepharitis and POD. RESULTS Brachycephalic dogs were significantly more likely to present with blepharitis than other breeds. Twenty five dogs had blepharitis alone [three dogs (2.9%) without and 22 dogs (21.5%) with cutaneous lesion beyond the periocular skin]. Seventy one of 102 (69%) presented with POD in addition to blepharitis. In six cases a differentiation between blepharitis and POD was not possible. Typical lesions included alopecia/hypotrichosis (97%), erythema (93%), eyelid oedema (50%) and crusts (39.2%). Allergic skin disease (52%) was the most common underlying cause of blepharitis, followed by infectious/parasitic diseases (21.5%), autoimmune disorders (17.7%) and neoplasia (4.9%). Four dogs could not be allocated to any of these disease groups. A diagnosis of parasitism was always accompanied by POD. Reduced tear production was detected in ten of the 53 dogs tested (18.8%). CONCLUSION Blepharitis occurring in the absence of other skin lesions is rare. The most common underlying cause of blepharitis is allergic dermatitis. Measurement of tear production should be recommended in all cases of blepharitis.
