A case of chronic lacrimal canaliculitis: revisiting the role of Actinomyces israelii

Three cases of Actinomyces isolation from the eye lesions of patients with a chronic and recurrent ophthalmic infection

“…An ocular actinomycosis mimicking meningioma caused by Actinomyces species in a 67-year-old female patient was described by Kobayashi et al [1]. The case of chronic lacrimal mir-journal.org Actinomyces ophthalmic infection canaliculitis caused by A. israelii in a 70-year-old retired male patient was described by Mohanty et al [16]. Bhole et al [17] described a case of keratoactinomycosis in a 50-year-old female farmer caused by Actinomyces species after vegetative trauma.…”

Canaliculitis mimicking cutaneous squamous cell carcinoma of the palpebral rim: A case report

“…1,2 Its aetiology is predominantly infectious, with organisms such as Actinomyces Israelii being responsible for a significant proportion of cases. [3][4][5][6] Symptoms may include pericanalicular reddening and swelling, mucopurulent secretions and chronic unilateral conjunctivitis.…”

“…2,6 Intraluminal concretions found in probing are highly specific to the disease and account for the metabolic behaviour of the microorganisms: they are composed of an internal tangle of mycelia fragments, sulphurous salts and a rosette of peripheral clubs, stabilized by a protein-polysaccharide complex, supposed to provide a resistance mechanism to host defences by inhibiting phagocytosis. 2,3,5,7 The first therapeutic step often includes antibiotic irrigation of the canalicula, which can be repeated upon recurrence of symptoms or inefficacy. However, the chances of resolution after medical therapy alone are low, making surgical canaliculotomy with curettage the gold standard treatment.…”
