Abstract:
AIM: To observe the changes of macular retinal structure and microcirculation in patients with pituitary adenoma(PA)by optical coherence tomography(OCT)and optical coherence tomography angiography(OCTA).METHODS: Cross-sectional study. A total of 40 PA patients treated at the department of neurosurgery, Affiliated Hospital of Guangdong Medical University from September 2021 to March 2023 were included as PA group, and 42 age- and gender-matched healthy volunteers were selected as normal control group. All patients underwent visual field, OCT and OCTA examinations, and the correlation of ocular parameters in PA patients was analyzed.RESULTS:The vessel density(VD)of each retinal layer in the macular area of the PA group was lower than that of the normal control group, and the superficial vascular complex(SVC)-VD in the macular area was positively correlated with the thickness of the macular ganglion cell complex(mGCC)(except the nasal side of the inner ring and the lower part of the outer ring; P<0.05). The thickness of mGCC in each quadrant of the macular area and the thickness of the circumpapillary retinal nerve fiber layer(CP-RNFL)in each quadrant were negatively correlated with the mean defect(MD)value of the visual field(P<0.05), and the area of the foveal avascular zone(FAZ)was positively correlated with the MD value(P<0.05).CONCLUSION:The combination of OCT and OCTA can fully understand the microscopic changes of retinal structure and microcirculation function in PA patients, which is of great value in evaluating the preoperative visual function of PA patients.
