  什么是麦粒肿

  麦粒肿即眼睑腺体的急性化脓性炎症。中医称为针眼。为葡萄球菌感染所致。屈光不正、糖尿病、消化功能紊乱、体质虚弱及不良卫生习,惯者易患此病。有内外之分,发生于睫毛、毛囊或周围的皮脂腺者,称为外麦粒肿;发生于睑板腺者,称为内麦粒肿。本病为常见病,多见于青少年,预后较好,无损于视力。但反复或多发者,日后可能影响眼睑外观或功能。

  麦粒肿的基本症状

  初起有眼睑痒、痛、胀等不适感觉,之后以疼痛为主,少数病例能自行消退,大多数患者逐渐加重。检查见患处皮肤红肿,触摸有绿豆至黄豆大小结节,并有压痛。如果病变发生在近外眼角处,肿胀和疼痛更加明显,并伴有附近球结膜水肿。部分患者在炎症高峰时伴有恶寒发热、头痛等症状。外麦粒肿3~5日后在皮肤面,内麦粒肿2~3日后在结膜面破溃流脓,炎症随即消退。也有部分麦粒肿既不消散,也不化脓破溃,硬结节长期遗留者。
