Inter-eye light sensitivity comparisons of the temporal and nasal hemifields between the left and right eyes were conducted in each patient to study left-right asymmetry. Upper-lower asymmetry was investigated by comparing the frequency of severe scotoma (light sensitivity 5 dB or less) in the upper and lower visual field quadrants in the temporal and nasal hemifields.Results: Left-right asymmetry was demonstrated in 61% of cases in the temporal hemifield and in 57% of cases in the nasal hemifield. Severe scotoma test points were investigated in the worse eye of each patient and were more frequent in the superotemporal quadrant of the visual field compared with the inferotemporal quadrant (P = 0.00029) and in the inferonasal quadrant compared to the superonasal quadrant (P = 0.00268).Conclusion: Asymmetric visual field defects between left and right eyes are common in patients with pituitary adenoma. Severe scotoma is more frequent in the upper quadrant of the temporal hemifield and in the lower quadrant of the nasal hemifield.Keywords: bitemporal hemianopsia, pituitary adenoma, asymmetry, Humphrey perimetry, light sensitivityKotoda YKotoda MOgiwara MKinouchi HIijima HDove Medical Pressarticlebitemporal hemianopsiapituitary adenomaasymmetryhumphrey perimetrylight sensitivityOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 317-324 (2020) |
