Evaluation of Tear Stability After Surgery for Conjunctivochalasis.
To evaluate the efficacy of surgical treatment for conjunctivochalasis using the Tear Film Stability Analysis System.
Fifteen eyes of 15 patients (74.5± 4.8 years; 14 females and 1 male) who had surgical reconstruction of the tear meniscus for conjunctivochalasis underwent evaluation with a symptom questionnaire, Schirmer I test, fluorescein tear film break-up time (FBUT), and break-up time index (BUI) measurement by Tear Film Stability Analysis System examinations that were performed preoperatively and 3 months after the surgery. Changes of these tear parameters were statistically analyzed using the paired t test.
After the surgery, the mean FBUT and BUI values significantly improved from 5.7± 3.2 s and 42.8± 18.7, respectively, to 8.4± 2.5 s and 60.7± 16.5, respectively (FBUT, p = 0.0438; BUI, p = 0.0036). The mean Schirmer test value showed no significant changes before and after surgery (p = 0.9064). Fourteen eyes (93.3%) had improvement of ocular symptoms after surgery. One eye (6.7%) with no improvement of ocular symptoms, FBUT, and BUI after surgery appeared to have aqueous tear deficiency.
CONCLUSIONS.: Surgical treatment for conjunctivochalasis was associated with improvement of tear stability and clinical dry eye symptoms.
