Abstract
Sho Ishikawa,1 Kouichiro Murayama,2 Naoko Kato1 1Department of Ophthalmology, Saitama Medical University, Saitama, Japan; 2Tsuruse Murayama Eye Clinic, Saitama, Japan Purpose: Various ocular surface disorders, such as dry eye, infectious and non-infectious inflammation, anatomical anomalies in lid structure, and/or obstruction of the tear outflow tract, can cause epiphora. However, few reports have described the proportions of causative diseases in patients with epiphora. Therefore, we investigated the frequent causes of epiphora in older adult patients.Materials and methods: We enrolled 220 patients (70 men, 150 women) who visited a primary eye care clinic from January 2016 to August 2017 with lacrimation as a chief complaint. The mean age of the patients was 61.3±10.9 years. The causes of epiphora were assessed by slit-lamp examinations, dry eye tests, fluorescein disappearance tests, and lacrimal pathway washing.Results: The causes of epiphora were dry eye in 96, conjunctivochalasis in 56, lacrimal obstruction in 30, conjunctivitis in 20, trichiasis in 16, and facial palsy in 2 patients. Ocular surface diseases were identified in 187 of the 220 (85%) patients who complained of epiphora. Conjunctivochalasis was observed in 36 of the 96 (38%) patients with dry eye. Among the patients with dry eye, 99% had short break-up time type dry eye, with the random break type being the most frequent type (61/96; 64%) in patients with epiphora.Conclusion: Among older adult patients whose main complaint was epiphora, 85% had ocular surface diseases. In contrast, only 15% of patients had lacrimal diseases. Short break-up time dry eye, especially the random break type, was the most frequently observed form of dry eye in our cohort.
