Morphometric differences between normal and dry eyes

ABSTRACT

The aim of the study was to quantify the anatomicdifferences in central corneal thickness, anteriorocular chamber depth, lens thickness, vitreouschamber depth, and ocular axial length betweennormal and dry-eyes. Central corneal thickness(CCT), ocular anterior chamber depth (ACD), lensthickness (LT), vitreous chamber depth (VCD)and ocular axial length (AL) were measured in 70normal subjects and in 58 subjects with dry-eyes.Central corneal thickness was measured withscanning-slit corneal topography while ocularanterior chamber depth, lens thickness, vitreouschamber depth and ocular axial length were measuredwith applanation ultrasound biometry.Central corneal thickness was 0.558±0.30 mmand 0.532±0.34 mm in normal and dry-eyes,respectively (p<0.001). Mean ocular anteriorchamber depth was 3.17±0.23 mm and 2.93±0.35mm in normal and dry-eyes, respectively(p=0.002). Lens thickness was 4.49±0.42 mm inthe dry-eye patients and 4.71±0.32 mm in thenormal subjects (p=0.022). Vitreous chamberdepth was 16.75±1.75 mm and 15.54±1.34 mm innormal and dry-eyes, respectively (p=0.001).Ocular axial length was 24.58±1.73 in normalsubjects and 23.07±1.48 in dry-eye subjects(p<0.001). We conclude that quantitative ocularanatomy values are lower in dry-eye subjects (AU)
