ABSTRACT
Purpose:
To establish normative data on anterior scleral thickness using the spectral domain anterior segment optical coherence tomography (AS?OCT).Methods:
In total, 200 eyes of 100 healthy subjects underwent AS?OCT scans in the temporal and nasal quadrants. The scleral + conjunctival complex thickness (SCT) was measured by a single examiner. Mean SCT was analyzed for differences across age groups, gender, and location (nasal versus temporal).Results:
Mean age was 46.4 ± 18.3 (21–84) years; male to female ratio was 5446. Mean SCT (nasal + temporal) of the right eye (RE) was 682.3 ± 64.2 ?m in males and 660.6 ± 57.1 ?m in females. In the left eye (LE), it was 684.6 ± 64.9 ?m in males and 661.8 ± 49.3 ?m in females. These differences between male and female for both eyes were statistically significant (P = 0.006 and P = 0.002). The mean SCT of temporal and nasal quadrants in the RE was 678.54 ± 57.50 and 666 ± 66.2 ?m, respectively. In the LE, the temporal mean SCT quadrant was 679.6 ± 55.8 ?m, and the nasal was 668.6 ± 63.6 ?m. Age had a negative correlation with SCT (?0.62 ?m/year; P = 0.03), and males had a higher temporal SCT than females (22 ?m higher; P = 0.03). After adjusting for age and gender in a multivariate analysis, temporal SCT was significantly (P < 0.001) higher than nasal SCT.Conclusion:
In our study, mean SCT decreased with age and males had a higher temporal SCT. This is the first study to evaluate scleral thickness in the Indian population, and the data can be used as a baseline for comparing variations in scleral thickness in disease.
