Orbital and adnexal cysticercosis is emerging as a far commoner disease than previously considered, both in endemic and nonendemic areas of cysticercosis. A review of the literature on orbital and adnexal cysticercosis found that it has a predilection for children and young adults with no definite sex predilection. The extraocular muscle form is the commonest type of orbital and adnexal cysticercosis. Lodgement of cysts in the subconjunctival space is another common site, followed by the eyelid, optic nerve, retro-orbital space and lacrimal gland. Association of orbital cysticercosis with systemic cysticercosis is quite rare. The clinical manifestations of orbital or adnexal cysticercosis are entirely different and depend on the location, size, relation to adjacent structures and stage of evolution of the cyst. Diagnosis of cysticercosis is based mainly on orbital imaging because of its highly specific appearance. Tissue diagnosis is not essential for initiating treatment. Medical therapy is the recommended treatment for the extraocular muscle form and retro-orbital cysticer-cosis. Surgical removal is advocated for subconjunctival and eyelid cysticercosis. Because of the limited number of cases of optic nerve and lacrimal gland cysticercosis, their treatment is controversial.

In this prospective, small case series, 3 patients with simple dacryops were analyzed along with a review of literature. All 3 patients in this series had classical clinical features of simple dacryops. All of them underwent complete cyst removal with the aid of a cryoprobe. Histopathology was compatible with dacryops. In 2 of the 3 patients, the cyst revealed calcification, which to the best of our knowledge has not been reported. None of the patients developed a recurrence. In conclusion, simple dacryops is an easily recognized clinical entity. This entity has been infrequently reviewed in the older literature, and in the last decade only 6 cases have been reported. Most of the patients underwent complete excision of the cyst with no recurrences.

This is the first clinical study in which polytetrafluoroethylene in the form of suture has been studied. Polytetrafluoroethylene suture was found to be a safe and effective sling material for frontalis suspension and it can be recommended for clinical use.

Pleomorphic adenomas of the lacrimal gland may present with duration of symptoms of less than 10 months. Cystic degeneration, squamous metaplasia, calcification or ossification may be observed in lacrimal gland pleomorphic adenomas, as has been described in pleomorphic adenomas of salivary glands. However, the presence of calcification and bone erosion radiologically in a lacrimal gland tumour does not necessarily indicate malignancy.
