The immortal Ologen: persisting 10 years after trabeculectomy
The surgical management of glaucoma has been evolving over the past few decades. In an attempt to improve the results of trabeculectomy, a number of modifications have been tried, of which Ologen (Aeon Astron, Leiden, The Netherlands) is one adjunct.1,2 Ologen is being extensively used for filtering surgeries and is known to undergo complete biodegradation within 90–180 days of implantation.3 We report a case of trabeculectomy failure in both eyes (BE) of a patient who had undergone augmented trabeculectomy with Ologen, which was seen to be retained for 10 years postsurgery.Primary apocrine adenocarcinoma of caruncle in an elderly male
Apocrine adenocarcinoma arises from the sweat glands of the body, which are densely located in the axillae, areola and nipple of breast, ear canal, perianal area, and external genitalia.1 Ocular adnexal apocrine adenocarcinoma is a rare tumour that arises from glands of Moll and therefore presents as an eyelid mass.2 However, these sweat glands are also present in the caruncle region of the eye. We present a rare case of rapidly progressing primary apocrine adenocarcinoma of the caruncle in an elderly male.Orbital metastasis from a primary salivary duct carcinoma: importance of long-term follow-up
Primary salivary duct carcinoma (SDC) of the parotid gland is a relatively uncommon tumour. Amongst the noted cases in the literature, metastasis of the primary SDC is known to involve the lungs, liver, bones, lymph nodes, gingiva, vagina, and rarely the orbit.1–4 The reported cases of orbital metastasis from a primary SDC have shown a good prognosis, whenever appropriate intervention was instituted at the earliest. In this report, we describe the clinical difficulties, investigations, and management of a metastatic SDC of the orbit that presented prior to manifestations at the primary location.Isolated conjunctival histoplasmosis in an elderly patient: a rare but important scenario
Histoplasmosis is a granulomatous infection caused by the dimorphic fungus Histoplasma capsulatum. It has two variants which are known to cause human infection: Histoplasma capsulatum var capsulatum and Histoplasma capsulatum var duboisii. Ocular manifestations are known in the form of involvement of the choroid and retina.1 Here, we describe the clinical features, diagnosis, and management of an isolated conjunctival histoplasmosis infection as a primary manifestation in an immunocompromised individual.Conjunctival angiomyxoma—rare but needs observation
Angiomyxomas are benign mesenchymal tumours that rarely involve periocular structures. The age at which patients present with them ranges from 4 to 60 years.1,2 These tumours commonly involve the pelvic area in females. Only a few cases of conjunctival and orbital angiomyxoma have been described in the literature.1–4 When they involve the periocular structure, they need special attention both during and after surgery. Here we describe the clinical features, diagnosis, and management in a case of conjunctival angiomyxoma.
