The compression of the optic pathway by the sellar masses can lead to visual dysfunction， with the most common lesion being pituitary adenoma. Tumor compression on different parts can cause different types of visual dysfunction， typically manifested as bilateral temporal visual field defects. Visual acuity and visual field examination are crucial in clinical evaluation， but are often limited by subjective and equipment factors. Optical coherence tomography（ OCT）， a non-contact， non-invasive imaging technique， provides an important basis for early diagnosis by assessing the thickness of the retinal nerve fiber layer（ RNFL） around the optic disc and the thickness changes of the macular ganglion cell complex（ GCC）. Optical coherence tomography angiography（ OCTA） further provides quantitative indexes by detecting the density of blood vessels at different levels of the retina. Also， it provides an important quantitative basis for early diagnosis and assessment of treatment effects， significantly improving the sensitivity and accuracy of visual function assessment. In recent years， the application value of OCT and OCTA techniques in the evaluation of visual function in patients with sellar mass has gradually emerged. This article mainly explores the latest progress of OCT and OCTA techniques in evaluating the visual function of patients with sellar masses， in order to provide clinicians with a more comprehensive visual function assessment plan， thereby improving the treatment effect and quality of life of patients.
