PURPOSE
To assess changes in ganglion cell-inner plexiform layer (GCIPL) thickness after cataract surgery using spectral-domain optical coherence tomography (OCT). METHODS: Forty-three eyes of 33 patients, who underwent cataract surgery were imaged with spectral-domain OCT before and after surgery to measure peripapillary retinal nerve fiber layer (RNFL) and GCIPL thickness, signal strength (SS), quadrant, 12 clock-hour RNFL thickness and sectoral GCIPL thickness. RESULTS: The postoperative SS, RNFL and GCIPL thickness were higher than before surgery (p < 0.05). Multivariate analysis showed that endothelial cell count and preoperative SS were significantly correlated with SS changes in RNFL parameters and preoperative SS was significantly correlated with SS changes in GCIPL parameters. Univariate analysis indicated that age was significantly correlated with RNFL thickness changes in RNFL parameters and no factor was correlated with GCIPL thickness in GCIPL parameters (p < 0.05). CONCLUSIONS: Cataracts may decrease peripapillary RNFL and GCIPL thickness measurements and SS on OCT scans. Peripapillary RNFL and GCIPL thickness measurements should be interpreted with caution in eyes with significant cataracts. |
