Abstract Details


To evaluate cross-sectional areas of conjunctivochalasis and tear. meniscus using Fourier-Domain RTVue-100 optical coherence tomography (OCT) before and after conjunctivochalasis surgery with amniotic membrane transplantation.


Prospective, nonrandomized, consecutive case study


24 eyes of 23 patients with symptomatic conjunctivochalasis were recruited for the study. All patients underwent crescent-shaped conjunctiva resection and amniotic membrane transplantation. Anterior segment OCT (AS-OCT) imaging was performed and tear break-up time was checked prior to and 3 months after the conjunctivochalasis surgery. Cross-sectional areas of conjunctivochalasis and tear meniscus at 7 locations (1 center, 3 nasal and 3 temporal areas) were measured in all patients.


The mean age of patients was 66.3 ± 10.79 years (aged 54 to 85). 16 patients were female and 7 were male. Mean tear break-up time was significantly increased from 2.30 ± 0.82 to 3.73 ± 1.3 sec following the surgery. Cross-sectional areas of conjunctivochalasis at all locations significantly decreased from 0.508 ± 0.43 mm2 to 0.006 ± 0.010mm2 (P < 0.001), whereas no significant changes in cross-sectional areas of tear meniscus at all 7 locations were observed after the surgery (from 0.025 ± 0.045 to 0.029 ± 0.039, P=0.463).


This study suggests that dispersed tears among each conjunctival fold in conjunctivochalasis patients were combined after the conjunctivochalasis surgery. AS-OCT imaging for conjunctivochalasis could be considered as an objective method for diagnosis of conjunctivochalasis and evaluation of surgical results. FINANCIAL INTEREST: NONE
