Purpose:
|
To compare lamina cribrosa (LC) thickness, measured by enhanced depth imaging-optical coherence tomography (EDI-OCT) in eyes with primary open angle glaucoma (POAG), primary angle closure glaucoma (PACG), juvenile open angle glaucoma (JOAG) and pseudoexfoliation glaucoma (PXG).
|
|
Methods:
|
In this cross-sectional study, optic nerve heads were scanned using EDI-OCT. LC thickness was measured in the mid-superior, central and mid-inferior regions along the vertical midline of the optic disc, and compared among the study groups.
|
|
Results:
|
A total of 112 eyes including 29 eyes with POAG, 29 eyes with PACG, 33 eyes with JOAG and 21 eyes with PXG were studied. Mean LC thickness was 140.79 ± 39 μm in POAG, 140.48 ± 39.1 in PACG, 106.5 ± 10.4 μm in JOAG and 96.04±19.4 μm in PXG eyes, respectively. LC was significantly thinner in JOAG and PXFG (both p values <0.05) but comparable in POAG and PACG (p=0.9). PXFG eyes had the thinnest LC (p=0.001).
|
|
Conclusion:
|
Eyes with PXFG demonstrated a thinner LC as compared to eyes with POAG, PACG and JOAG. These findings may have implications in the appearance of glaucomatous cupping in PXFG.
