Baseline characteristics of the patients.

PurposeTo investigate the factors affecting visual field recovery in patients with pituitary adenoma following surgical removal, both eyes of 35 patients with pituitary adenoma who had been followed up for > six months post-surgery were retrospectively analyzed.Material and methodsPre- and post-operative visual acuity, visual field test, retinal nerve fiber layer (RNFL), and ganglion cell inner plexiform layer (GCIPL) thickness were investigated. The average age of the 35 patients was 58.3 ± 11.5 years. Preoperatively, 30 eyes (mean average RNFL thickness, 99.73 ± 5.89 μm) and 40 eyes (mean average RNFL thickness, 77.55 ± 8.35 μm) were included in the thick (≥ 90 μm) and thin RNFL group (ResultsIn the thick RNFL group, pre- and post-operative mean deviation (MD) and pattern standard deviation (PSD) were favorable (all p 0.001), tumor volume (OR, 1.110, p = 0.002), higher preoperative MD values (OR, 0.858; p ConclusionsEyes with preoperative higher MD and thick temporal RNFL showed more improvement in their visual fields postoperative. Preoperative thick RNFL could be a potential predictor of visual field recovery following TSA-TR, while macular GCIPL thickness does not appear to be a reliable predictor.
