ABSTRACT
PURPOSE:
To evaluate thicknesses of sclera and lamina cribrosa (LC) in central retinal vein occlusion (CRVO).METHOD:
Thirty-two patients with CRVO (mean age 62.2 ± 11.6 years, women/men 18/14) and 35 age- and sex-matched healthy volunteers were included into the study. Scleral thickness was measured at scleral spur and at 1 to 3 mm from scleral spur in four quadrants (temporal, nasal, super, and inferior) using anterior segment optical coherence tomography. Lamina cribrosa was measured using optic disk enhanced depth imaging optical coherence tomography.RESULTS:
The sclera was thicker in affected eyes of the CRVO group than healthy subjects at scleral spur in four quadrants (738.7 ± 30.9 µm vs. 702 ± 30.8 µm in temporal, 700.4 ± 19.7 µm vs. 673 ± 13.7 µm in superior, 693 ± 19.3 µm vs. 665.3 ± 24.2 µm in nasal, 810.7 ± 28.9 µm vs. 784.5 ± 23.7 µm in inferior quadrants, respectively; P < 0.05 for all). Lamina cribrosa thickness in affected eyes of the CRVO group was significantly higher than that of healthy subjects (285.2 ± 12.7 µm vs. 266.4 ± 10.7 µm, respectively; P < 0.01). The correlation between scleral thickness and LC thickness was moderate at scleral spur of temporal and superior quadrants of affected eyes (r = 0.510 and r = 0.420, respectively).CONCLUSION:
Thicknesses of sclera and LC are increased in the CRVO, which may play a role in the pathogenesis of the disease.
