高度近視會導致真正的玻璃體變性或液化

現在生活變得越來越電子化,大多數人每天要麼在電腦前工作,要麼在手機前工作。雖然電子產品可以提高工作質量,但它對視力也非常有害。一直以來,對於這些電子產品來說,不僅輻射很大,還會造成近視,尤其是現在的孩子,每天玩手機,眼睛一大早就被破壞了。治療近視的方法有很多。讓我們來學習如何恢複近視視力。


小童近視問題越來越嚴重,處理不當有機會引起近視併發症。如近視突然飆升、飛蚊變多、視野有閃光等,應立即向眼科醫生求診,為兒童作近視評估,及早正視視力問題,減低產生眼睛健康風險。在放松狀態下,平行光線穿過眼睛的屈光系統,聚焦在視網膜的前部。這叫近視。近視也被稱為近視,因為他們只能看到近視和近視。當眼睛處於靜止狀態時,來自無窮遠處的平行光線通過眼睛的屈光系統折射,成為視網膜前面的焦點。在視網膜上,它形成一個模糊的圖像。遠視力明顯下降,近視力正常。遺傳性近視被認為是一種遺傳傾向,尤其是高度近視。但對於一般近視來說,這一趨勢就不那麼明顯了。如果有遺傳因素,發病年齡較早,且度數在600度以上。但也有高度近視,沒有家族史。高度近視屬於常染色體隱性遺傳,一般近視屬於多因素遺傳病。

作為家長,有甚麼方法可以緩解小朋友近視加深的問題呢?隨著眼軸的增加,青少年近視患者的眼球不斷擴張,這在眼球標本中可以看到,眼球標本比正常眼球大得多。在眼球放大過程中,鞏膜和脈絡膜可以根據眼睛內部信號的需要生長,但視網膜不能隨之生長。為了附著在擴大的鞏膜和脈絡膜上,視網膜周圍會有很多裂隙或晶格變性,這將導致未來視網膜脫離的前期病變。高度近視開角型青光眼的發病率是普通人的6到8倍,但由於青光眼臨床症狀不明顯,視功能下降往往被高度近視症狀掩蓋,容易被忽視。高度近視患者晶狀體後極部皮質混濁也很常見。由於高度近視患者色素上皮細胞的病理改變影響了視細胞光化學變化的反應過程,暗適應時間相對較長。

醫生建議近視控制眼藥水可用到完成發育後才停用,以達到近視控制最佳效果。高度近視會導致真正的玻璃體變性或液化,導致明顯的飛蚊。感覺到光線、火花、閃光或陰影在你眼前漂移。主要表現為眼球後極向後擴張,神經和黃斑周圍視網膜變性萎縮,矯正視力下降。近視程度越高,發病率越高。由於眼軸延長,眼球後部變薄,視網膜和脈絡膜萎縮退化,出現裂隙,導致不同區域的出血和視網膜脫離,導致失明。此外,黃斑變性也是高度近視的最大風險,其特征是視力扭曲、視力喪失,最終失明。高度近視因為並發症不能做劇烈運動,所以以後找工作、找對象都會受到限制。這也是青少年兒童患上真近視的原因,明知有些無法完全恢複,但仍需防控!
