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。

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.

暂未有足够数据显示此类镜片能有效减慢近视加深，不过本中心亦不反对儿童配戴此类镜片，舒缓眼镜疲劳。

另中心有提供角膜矫形镜片供近视持续加深之学童配戴。

由于根据阁下提供资料难以断症，建议接受全面眼科视光检查，由眼科视光师详细检查是否晶状体、玻璃体或视网膜出现问题，再作出诊断及建议。
