    Visual Prognostic Value of the Optical Coherence Tomography and Photopic Negative Response in Chiasmal Compression
    Purpose. To investigate the potential of the optical coherence tomography (OCT) measurement of retinal nerve fiber layer (RNFL) thickness and ganglion cell complex (GCC) area and photopic negative response (PhNR) for predicting postoperative visual outcome in chiasmal compression, prospectively. Methods. Eighteen eyes of 18 patients undergoing chiasmal decompression surgery were prospectively assessed before, and 3 months after surgery with standard automated perimetry (SAP), OCT and PhNR. Preoperative measurements were compared with 20 eyes of 20 age matched controls. Spearman's correlation and regression analyses were conducted to evaluate the relationship between preoperative RNFL thickness, GCC area, PhNR/b-wave amplitude ratio ...
