The overall surgical outcomes of external DCR were favorable in this case series. Site of obstruction was an important risk factor for functional failure in cases with primary lacrimal drainage obstruction. A small lacrimal sac was also found to be a risk factor for functional failure in cases with primary NLDO.
Purpose Intratarsal keratinous cysts (IKCs) have been frequently misdiagnosed as chalazia or epidermal cysts. We reviewed a series of cases of IKCs to identify clinical features that distinguish IKCs from other eyelid diseases. Methods We retrospectively reviewed the medical records of 17 suspected IKC patients between January 2004 and September 2014. Results Seventeen patients who were clinically suspected to have IKC were enrolled. All patients presented with noninflamed eyelid nodules fixed to the tarsus. Among them, 12 biopsy specimens were available and 11 patients (91.7%) were diagnosed with IKC, with a pathological finding of stratified squamous cell lining with keratin material. The mean patient age was 55.1 years (31-71). Six patients had a surgical history of incision or incomplete excision of the lesion, followed by recurrence. On eyelid eversion, five patients showed a white-yellow nodule, and three patients had a bluish cystic lesion. The diameter of the nodules ranged from 4 to 10 mm. The intracystic material was a milky white fluid. Ten patients underwent a complete surgical excision including partial tarsectomy and there was no recurrence. Conclusions IKC can be distinguished from other intratarsal lesions by a characteristic tarsal nodule fixed to the tarsus. To prevent recurrence, complete excision with partial tarsectomy is needed.
Purpose To report long-term outcome of new surgical technique for prolapsed subconjunctival orbital fat. Patients and methods Retrospective study was conducted on 48 eyes of 37 patients who underwent excision of prolapsed subconjunctival orbital fat with conjunctival fixation to the sclera. Complications and recurrence were evaluated. Results The mean follow-up period was 39 months (range, 8-101 months). Two eyes (4.4%) developed recurrence at 4 and 8 years after surgery. No long-term complication was found. Conclusions The new surgical technique to manage prolapsed subconjunctival orbital fat using conjunctival fixation to the sclera was very useful and effective, with few recurrence and no long-term complication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
