在光线比较充足的地方(例如自修室)便会看见中很多半透明黑色条状的物体在移动,程况只发生在眼球移动的时候。那些物体会随着眼球移动的方向移动.( 如由左边望向右边时,物体便由偏左移至偏右)本人只有十八岁,我很担心怕会影响日后视力甚至至盲,但又救助无援,翻查网上亦不见这案例。住所附近又没有眼睛专科,也不知一般诊所有否验眼服务。若可解答,实感激不尽!

据阁下描述,该半透明黑色条状怀疑是因玻璃体退化而产生的「飞蚊」(可呈粒或条状),通常深近视患者会出现较多「飞蚊」,但若短时间内突现大量,则担心有视网膜病变或脱落的问题,建议定期接受「全面眼科视光检查」,确保眼睛内外健康。

本中心提供的「全面眼科视光检查」主要为3至80岁以上的市民服务。

我弧度9.0带8.6大眼仔可以吗?

除角膜弧度外,隐形眼镜配戴者亦必须考虑其角膜健康、泪水分泌、隐形眼镜移动程度及湿润度、眼睛舒适度等。

建议先接受隐型眼镜验配检查,由眼科视光师建议合适的镜片、屈光度、厚薄及配戴模式

我两只眼有不少红筋,唔会消退,而且红筋尽头会有一点点紫色点,也不会消退,是有什么问题吗?有解决方法吗?我两眼本身有六百多度近视,有以上问题跟深近视有关吗?谢谢!

该「红筋」应该是属于眼球巩膜上的正常血管。巩膜位于透明结膜下,呈白色,其血管通常较结膜的血管为大、数量较少,亦含正常色素,如紫红。

眼睛一旦受到刺激,如眼干、长时间对电脑工作、感染、发炎等,结膜和巩膜的血管便会脤大充血。有时单靠照镜是难以分辨究竟是结膜、巩膜或两者的血管充血。

建议定期接受「全面眼科视光检查」,由眼科视光师详细检查眼睛内外健康。

Is there any cure for retina pigmentosa degeneration and macula degenaration? Is there any difference between the two? Can you recommend any expert doctors to me?

RP is the formation of pigments in the retinal layers, it is a hereditary disease and the development of the pigments usually starts from peripheral retina, so the visual field lost is from outside and gradually moves inwards/to central area. There is no cure for this disease and most cases will go blind in late stage of the disease.

MD is the degeneration of the macular area, affected eye has damages in central visual field as macula is responsible for central vision. As the damage is localized in central area, the peripheral field is usually

retained, except in a severe condition when a secondary retinal detachment occurs, the peripheral field could be affected too. The damage in visual function cannot be recovered, the current methods (lutein/beta-

carotene supplement/drug injection/photodynamic therapy) in management macular disease is preventive in nature, i.e. prevent any further deterioriation of the damage.

Sorry, there is no information about night blindness specialists.
