To analyze the correlation between clinical features and degree of scleral invasion using anterior segment optical coherence tomography. METHODS: The size, elevation, color, and degree of vascularization were examined in 50 patients (17 males and 33 females) who visited our clinic between February 2017 and April 2018. The thickness and scleral involvement were analyzed by anterior segment optical coherence tomography. RESULTS: The average horizontal diameter of the pinguecula was 2.37 ± 1.12 mm, which showed significant positive correlations with the thickness and dimension (correlation coefficients: 0.34 and 0.42, respectively). The vertical diameter was 2.21 ± 0.91 mm, which showed significant correlations with thickness, scleral involvement, and dimension (correlation coefficients: 0.22, 0.61, and 0.33, respectively). The correlation coefficient with scleral invasion thickness was as high as 0.61. The average diameter was 2.29 ± 0.97 mm, which was also significantly correlated with thickness and dimension (correlation coefficients: 0.40 and 0.54, respectively). Overall thickness was significantly greater in the elevation group (average 0.66 ± 0.35 mm) than the flat group (0.57 ± 0.23 mm). Thickness was significantly greater in the severe vascularization group (0.70 ± 0.19 mm) than in the less severe vascularization group (0.50 ± 0.13 mm) (p = 0.01). CONCLUSIONS: Anterior segment OCT findings revealed that the larger and more vascularized pinguecula were significantly thicker and had more scleral involvement.
