Abstrakt: Purpose: To evaluate the lamina cribrosa, retinal nerve fiber layer (RNFL), and macula in patients with primary open-angle glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG) and healthy individuals using enhanced depth imaging (EDI) of spectral-domain optical coherence tomography (SD-OCT).
Methods: A total of 158 eyes were included in the study, comprising 58 eyes of 29 patients with POAG, 50 eyes of 25 patients with PEXG, and 50 eyes of 25 healthy individuals. The lamina cribrosa thickness (LCT) (at three locations), lamina cribrosa depth (LCD), RNFL thickness, and the macular thickness were measured using the EDI mode of the SD-OCT. The results were compared among the three groups.
Results: In both POAG and PEXG groups, the LCT was significantly thinner in the center, mid-superior, and mid-inferior areas in both eyes than in the control group (p < 0.001). However, no statistically significant difference was observed between the POAG and PEXG groups in terms of LCT at all three measurement locations in both eyes (p > 0.05). The LCD was significantly lower in the control group compared to the POAG and PEXG groups (p < 0.05), but there was no significant difference between the POAG and PEXG groups (p > 0.05). The RNFL thickness was significantly lower in both the POAG and PEXG groups compared to the control group in both eyes (p < 0.05).
Conclusion: The LCT and LCD of patients with POAG and PEXG were thinner than those of healthy individuals, but there was no significant difference between the patients with POAG and PEXG.
