我想問...

  • 本人30歲,左眼近視,右眼近視+弱視,請問仲有無得變好

    一般情況下在成人階段,視覺系統發展已完成,弱視問題應該不會有太大改善及變化。成人視覺訓練的成效要視乎視力及弱視的程度、且進展較慢。建議先接受全面眼科視光檢查,再評估視覺訓練的適用方案。

  • 小女4歲,左眼健康,但右眼225度散光,請問年齡愈大,在配帶合適眼鏡後,散光會否減少?

    大部份的散光是先天性,度數變化不大。另如眼皮過緊、經常摔眼有機會令散光加深。配戴合適眼鏡有助小朋友視物清晰及視覺發展,但較難大幅度減少散光。

  • 請問有腎病(在家中腹膜透析)的病人, 晚上瞓唔到, 日間才瞓. 睇嘢反白, 係乜原因? 除了睇腎科, 還可甚麼處理呢?請賜教.

    難以為閣下作判斷,建議看眼科專科醫生作詳細眼睛檢查以找出真正原因。

  • BB 一歲, 去studio 影相不斷用閃光燈, 有沒有問題?

    一般情況下,正常合理地使用閃光燈拍照是沒有問題的,只要不是過度頻密或超近距離地使用,基本上閃光燈是不會傷害到眼睛的。

  • 我每隔2-3個月就會出現看到閃亮波浪紋圈在逐漸擴散,即使閉上眼睛,那影像還是存在,還是在逐漸擴散,直到不在視線範圍內。請問這是什麼原因。

    根據閣下描述未能判斷。如看到的是頻密的閃光,則擔心有機會有視網膜病變或脫落的徵狀,建議閣下作詳細眼睛檢查,以查明真正原因。

  • 本人近兩星期來,眼前都有白霧,眼水很多,抹極都眼矇矇的,是否有問題?

    有機會是度數問題或眼乾等原因所致,但實際原因未明,建議找眼科視光師作全面眼科視光檢查。

  • 我雙眼近眼睫毛位經常覺得痕癢,有需要檢查嗎?

    可能與眼皮敏感、發炎、眼妝有關,如情況持續,建議約見眼科醫生找出原因及是否需要藥物處理。

  • 眼臉炎洗唔洗睇醫生?

    由於可能性太多,發炎可能與細菌感染或油脂分泌過剩有關,需多注意日常眼部清潔及護理。建議找眼科視光師或眼科醫生作詳細眼睛檢查,查明真正原因。

  • Eye Floater treatment

    The jelly-like substance filling the space between the crystalline lens and the retina is called “vitreous humour”. The vitreous humour degenerates and liquefies when we get older, at which time we start to see floaters. Floaters can be moving opacities of various shapes and sizes (dots, circles, lines or spider webs). Physiological floaters usually occur when we are looking at a bright homogenous background such as a white wall or the blue sky. The floating opacities are few in number and remain unchanged over time. They represent normal physiological changes of the vitreous humour. As we age, the vitreous humour undergoes the processes of synchysis (liquefying) and syneresis (dehydrating and shrinking). These are normal agerelated degenerations.

    Pathological floaters appear suddenly and may occur in great numbers. They may suggest bleeding within the vitreous humour, inflammation of the uvea or separation of the posterior vitreous humour from the retina. If the floaters are accompanied by flashes or visual field defects, it may indicate retinal tear or retinal detachment. When the vitreous humour contracts and detaches from the retina, it is called acute posterior vitreous detachment (acute PVD), at which time sudden onset of floaters and flashes occur. Floaters can be caused by vitreous opacities or haemorrhages, whereas flashes are caused by the vitreous humour pulling on the retina. An urgent dilated eye examination is essential to check for retinal tears, which should be repaired with laser as soon as possible, to prevent it from evolving into retinal detachment within a few hours.
