可怕！深圳一男子被蚊子"親了一口，眼睛卻看不清了！

2019-11-15 09:28來(lái)源：壹深圳

為何登革熱引起視力下降？陳主任認為，首先是因為感染登革熱后，人體免疫介導機制受影響，補體系統激活，進(jìn)而導致視網(wǎng)膜血管通透性增高，引起小血管擴張、黃斑水腫、視網(wǎng)膜血管炎、視網(wǎng)膜動(dòng)脈阻塞等；其次，登革熱引起的血小板及凝血功能障礙也會(huì )導致視網(wǎng)膜內深、淺層出血、結膜下出血及玻璃體后界膜下出血等，影響患者視力。

據了解，登革熱是由登革病毒引起、經(jīng)伊蚊叮咬傳播的一種急性傳染病。癥狀主要為：發(fā)熱、頭痛、肌肉和關(guān)節痛等，如進(jìn)一步惡化，可能出現休克，甚至危及生命。而登革熱相關(guān)眼病的眼部表現缺乏特異性，容易漏診、誤診。

專(zhuān)家提醒，前往登革熱高發(fā)地旅游時(shí)，要提高自我保護意識，做好個(gè)人防蚊保護措施。外出時(shí)可穿淺顏色的長(cháng)袖衣裳和長(cháng)褲，裸露皮膚涂抹驅蚊劑，特別是耳后、頸等部位。租住衛生條件好、最好有空調的賓館，避免因蚊蟲(chóng)叮咬而感染登革熱病毒。如出現發(fā)熱、皮疹等癥狀，應及時(shí)到正規醫療機構就診，并告知醫生流行區接觸史和蚊蟲(chóng)叮咬史，接受正規治療。如出現視力下降也要及時(shí)前往專(zhuān)科檢查治療。
