黄斑区成病变重灾区 黄斑区位于眼底中央,是我们看清细节、辨别颜色的关键部位。 陆军特色医学中心眼科 宣杰 近年来,随着电子产品的普及,长时间、近距离用眼已成常态,高度近视的患病率显著上升。高度近视 者因眼球结构已发生改变,眼底病变风险显著增高,每年一次的专业眼底检查,是一项必要的预防性筛 查,是预防视力丧失的关键防线。 来自眼球深处的真正威胁 高度近视,通常是指近视度数≥600度。正常眼球近似球体,而高度近视的眼球因前后径拉长,形状更 像一枚被拉长的鸡蛋,这种形态变化带来的首要风险是视网膜被过度拉伸而变薄。视网膜就像一件被撑 大的毛衣,组织变薄、脆弱,甚至出现萎缩孔或裂孔。这些看似微小的破损,却是视网膜脱离的潜在起 点。 通过每年的定期眼底检查,医生可筛查出视网膜变性区及裂孔等致盲隐患,并通过门诊十分钟就可完成 的激光光凝术,避免视网膜脱离的风险。然而,视网膜脱离并非高度近视唯一的隐患。眼球变形还会改 变内部结构,导致眼压逐渐升高,进而诱发开角型青光眼。这种疾病进展缓慢且症状隐匿,许多患者在 视野严重受损时才察觉异常。 高度近视者一定要建立"眼底年检"意识,每年至少进行一次完整的眼底检查。 专家点评 陆军特色 ...

Core Viewpoint - The article highlights the increasing incidence of retinal detachment among young individuals, particularly those with high myopia, emphasizing the importance of regular eye examinations to prevent severe vision loss [1][7]. Group 1: Retinal Detachment in Young Patients - Young patients often exhibit no obvious symptoms in the early stages of retinal detachment, leading to delayed intervention and potentially severe outcomes [1][7]. - A case study of a 25-year-old male with 700 degrees of myopia illustrates how neglecting eye health can result in irreversible vision damage, requiring complex surgical procedures [4][6]. - The article stresses that early detection through routine eye exams can allow for simple laser treatments to prevent the progression to retinal detachment [7][8]. Group 2: Risk Factors and Prevention - High myopia, defined as exceeding 600 degrees, is identified as a significant risk factor for retinal detachment, with the condition being likened to a balloon that stretches and thins the retina [6][7]. - The article provides recommendations for eye care, particularly for high myopia patients, including annual dilated eye exams and immediate consultation if symptoms like sudden vision changes occur [9][10]. - The importance of comprehensive eye examinations is emphasized, as standard vision tests may not detect underlying retinal issues [9].
