Abstract Details

Purpose:

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.

Setting:

Prospective, nonrandomized, consecutive case study

Methods:

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.

Results:

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).

Conclusions:

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
