該「紅筋」應該是屬於眼球鞏膜上的正常血管。鞏膜位於透明結膜下，呈白色，其血管通常較結膜的血管為大、數量較少，亦含正常色素，如紫紅。

眼睛一旦受到刺激，如眼乾、長時間對電腦工作、感染、發炎等，結膜和鞏膜的血管便會脤大充血。有時單靠照鏡是難以分辨究竟是結膜、鞏膜或兩者的血管充血。

建議定期接受「全面眼科視光檢查」，由眼科視光師詳細檢查眼睛內外健康。

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.

暫未有足夠數據顯示此類鏡片能有效減慢近視加深，不過本中心亦不反對兒童配戴此類鏡片，舒緩眼鏡疲勞。

另中心有提供角膜矯形鏡片供近視持續加深之學童配戴。

由於根據閣下提供資料難以斷症，建議接受全面眼科視光檢查，由眼科視光師詳細檢查是否晶狀體、玻璃體或視網膜出現問題，再作出診斷及建議。
