目的 :探讨垂体瘤CT结果与眼部表现的关系。方法 :对 5 2例垂体瘤患者进行视力、眼底和视野检查并与CT结果进行分析。结果 :CT结果显示 :肿瘤直径≤ 10mm 6例 ,11～ 2 0mm 13例 ,2 1～ 30mm 15例 ,31～4 0mm 11例 ,>4 0mm 7例。视力 <1.0的 72眼 (6 9.2 % ) ,眼底异常的 5 9眼 (5 6 .7% ) ,36例 6 6眼 (6 7.3% )出现视野缺损 ,其中 18例 (36 .7% )表现为典型的双颞侧偏盲 ,眼球运动障碍 2例 (1.9% )。 11例 (2 1.2 % )以眼部症状为首诊 ,4 0例 (76 .9% )有眼部异常表现 ,其中肿瘤直径≤ 10mm 2例 ,11～ 2 0mm 7例 ,2 1～ 30mm 13例 ,31～ 4 0mm 11例 ,>4 0mm 7例。结论 :垂体瘤可引起视力下降、视野缺损、视神经萎缩和眼球运动障碍 ,视力、视野损害的程度与肿瘤大小相对应。对不明原因视力下降者 ,应进行详细的眼底和视野检查 ,并结合CT扫描 ,防止垂体肿瘤误诊。
Objective: To investigate the relationship between CT findings and ocular manifestations in pituitary adenomas. Methods: Visual acuity, fundus and visual field were examined in 52 cases of pituitary adenomas and analyzed with CT results. Results: The results of CT showed that there were 6 cases of tumor diameter ≤ 10 mm, 13 cases of 11 ~ 20 mm, 15 cases of 21 ~ 30 mm, 11 cases of 31 ~ 40 mm, 7 cases> 40 mm. There were 72 eyes (62.2%) with visual acuity <1.0, 59 (5.6%) with fundus anomalies and 36 (66.3%) with visual field defects in 36 cases (36.3%), of which 18 As a typical double-temporal hemianopia, eye movement disorders in 2 cases (1.9%). Of the 11 eyes (21.2%) who were diagnosed with ocular symptoms, 40 (76.9%) had ocular abnormalities, including 2 cases with tumor diameter ≤ 10 mm, 7 cases with 11 ~ 20 mm and 13 cases with 21-30 mm , 31 ~ 4 0mm 11 cases,> 4 0mm 7 cases. Conclusion: Pituitary tumor can cause decreased visual acuity, visual field defect, optic atrophy and eye movement disorders, visual acuity, visual field damage extent corresponds with tumor size. For unexplained vision loss, should be detailed fundus and visual field examination, combined with CT scan to prevent misdiagnosis of pituitary tumors.
