Purpose: To compare the anatomical pattern of lacrimal drainage system obstruction (LDSO) associated with topical anti-glaucoma medications (AGM) with a control group. Methods: In a cross-sectional controlled study, case group included patients on topical anti-glaucoma medications and control group included patients with no history of glaucoma, free of ocular disease, and not using topical medications. Data recording, eye examination, and categorization of patients into case and control groups were performed by a senior ophthalmology resident. Diagnostic probing and irrigation test was performed by an oculoplastic surgeon who was masked to the patients’ data. Chi-square (X2) and tests were used to assess the effect of sex and systemic diseases, as well as logistic regression analysis with intra-cluster correlation for the effect of topical anti-glaucoma medications on lacrimal drainage system, and then independent sample t-tests to compare the mean ages, plus the binary logistic regression test for the effect of increasing age on LDSO. Results: There were 128 eyes of 96 patients in the case and 277 eyes of 172 patients in the control group. Two groups were similar regarding to the age, sex, and associated systemic disorders (0.3

Patients with conjunctival cicatrizing disease may develop lacrimal obstruction. Little is published on lacrimal obstruction as the presenting feature of otherwise asymptomatic cicatrizing conjunctival disease. The records of all patients presenting between 1994 and 2015 with lacrimal obstruction found to have cicatrizing conjunctival disease were reviewed. Demographic details, clinical findings, disease progression and treatment were analyzed. Thirty-five patients (25 female), aged 43–91 years (median 74, mean 71.3 years) had epiphora and a mild conjunctival cicatrizing process. Nine patients had onset of epiphora after cataract surgery. All except one patient had obstruction of the proximal lacrimal system (punctum and/or canaliculus). In 14 cases, the obstruction was unilateral (both puncta or canaliculi), with one progressing to bilateral obstruction after 11 years. In 19, all 4 puncta or canaliculi were obstructed. Two patients had unilateral nasolacrimal duct obstruction; one developed contralateral canalicular obstruction 2 years later. Conjunctival biopsies were obtained in 19 of 35 cases (54%), and OCP immunohistochemistry was positive in 7/19 (37%). All other biopsies showed chronic inflammation. Two patients had lichen planus. In follow-up (range 0.1–11 years, mean 3.2 years), 2 patients’ conjunctival disease progressed mildly, and 3 progressed moderately, with 2 of these 5 having positive OCP immunohistochemistry, and 1 having lichen planus. Patients with conjunctival cicatrization may present with lacrimal obstruction, usually punctal or canalicular. Conjunctival disease is usually mild and non-progressive, but patients should be monitored for disease progression. [ABSTRACT FROM PUBLISHER]

BACKGROUND After the advent of dacryocystorhinostomy (DCR), dacryocystectomy (DCT) was regarded as mutilant surgery and reserved for lacrimal sac tumors. PURPOSE To present current indications for dacryocystectomy. METHODS Eighteen eyes from 11 patients subjected to DCT were reviewed retrospectively. Nine patients had chronic dacryocystitis confirmed by dacryocystography and two patients had lacrimal sac tumors. RESULTS The indications for DCT were: three patients with systemic medical problems, three patients with dry eye, two cases of lacrimal sac tumors, two cases of traumatic dacryocystitis and one case of cutaneous leishmaniasis. Dacryocystitis was resolved in 17 of 18 eyes; the two cases of tumor evolved without epiphora. One patient (traumatic dacryocystitis) had recurrence of dacryocystitis. CONCLUSIONS DCT is mainly performed when a lacrimal sac tumor is suspected but, since it avoids the intra- and postoperative complications related to dacryocystorhinostomy, it can be indicated in cases of dacryocystitis with significant lacrimal discharge and an enlarged or altered lacrimal sac.
