The Effects of Surgical Punctual Occlusion on Patients with Aqueous Deficient Dry Eye

Purpose: To analyze the improvement of symptoms and signs of dry eye after surgical punctual occlusion and to evaluate the effects of secondary systemic disease in dry eye patients. Methods: From March 2011 to July 2014, 15 eyes of 8 dry eye patients with a history of punctal plug insertion underwent surgical punctal occlusion. Schirmer test was measured based on mean 2.9 mm. The patients consisted of 4 dry eye patients with Sjogren’s disease, 1 with rheumatoid arthritis, 1 with graft-versus-host disease (GVHD), and 2 with no secondary systemic disease. Preoperative and postoperative ophthalmic examinations of log MAR visual acuity, subjective symptoms, corneal staining(National Eye Institute [NEI] score), and tear break-up time (BUT) were performed and the effects of secondary systemic disease in dry eye patients were evaluated. The results of surgical punctual occlusion were analyzed. Results: All patients showed a statistically significant improvement of log MAR visual acuity, subjective symptoms, corneal staining (NEI score), and tear BUT. The patients with rheumatoid-related diseases showed improved symptoms after surgery, but the patient with GVHD showed no significant improvement after surgery. Among the study patients, 80.0% showed completely closed punctum and 20.0% showed partial recanalization. Conclusions: Surgical punctal occlusion is an effective alternative in patients with severe aqueous deficient dry eye who show recurrent punctal plug loss or complications associated with punctal plugs.
