How is your retina?                                                                             
If you experience the following symptoms, your retina or macula might have problems:
  — Straight lines appear wavy or faces appear distorted
  — Doorways seem crooked
  — Objects look smaller or far away
  — A blurry or blind spot in the center of your vision  
  — More light is needed when looking at objects up close
  — Print begins to appear more blurry
  — Colors seem less bright
  — Hazy vision  

Where is the retina and macula? Image the structure of your eye like a traditional camera. Retina is in the back of your eye like the film inside of the camera. The center of the retina is the macula where the most  light-sensitive cells that allows you to see color and fine detail. Images received by retina are sent through optic to the brain for processing. Retina or macula, once damaged, can lead to irreversible vision loss. Age-related Macular Degeneration (AMD) is a leading cause of vision loss in Americans over the age of 60 and it occurs in 2 different forms. The dry AMD is more common when light-sensitive cells in the macula slowly break down, leading to a gradual blurring of central vision. Wet AMD occurs when abnormal blood vessels grow under the macula, often leaking blood and fluid, severely damage the macular, leading to a rapid loss of central vision.   How do you know if you have AMD? The most important way to detect AMD is to have Dr. C. K. Chan perform certain tests during a medical eye exam on you with the most advanced in-office specialized equipments such as OCT ( optical coherence tomography), fundus digital camera and slit-lamp bio-microscope. Please call for an appointment. 

Amsler Grid checks- using the grid to check your vision daily gives you an early warning of AMD. Before you perform the daily eye test, if you wear reading glasses, please make sure you have them on. Keep the grid 14 inches away from your face. Test one eye at the time. Cover one eye with your hand. Stare at the center dot. Do any lines look wavy to you? Are any lines or portion of the lines in the grid missing? Do any boxes look like they are of different sizes from the others? If so, call Dr. Chan for an appointment without delay.

你的視網膜健康嗎?

如果你發現眼睛看東西時有下列現象,那庅你的視網膜或黃斑部可能有問題:
  — 直線條看起來不直,呈波浪狀,或者看人臉,臉會变形歪扭
  — 門框看起來不直 — 東西看起來比較小而且離自已較逺
  — 中央視力糢糊或出現完全看不見的盲奌
  — 看近物時特別需要更強的光線
  — 書報上的文字特別糢糊 — 顏色看起來不鮮明
  — 視力朦朧  

視網膜和黃斑部是什庅? 如果把眼睛的結構当作一個傳統的照相機,視網膜便是相機內部的底片,底片正中心便是黃斑部,此處有最密集的感光細胞,讓你看到東西的顏色和其微小的細節。眼睛看到的事物形相,由此接收經視神經傳送至大腦解讀。

視網膜和黃斑部是極為重要而珍貴的組織,一失而不可復得. 有了病變,便可導至視力永久性損坯或失明, 此時配上再好的光學眼鏡也於事無補。 年老引起的黃斑退化症(AMD)是導至美國60歲以上人失明的主要病因,它又分乾性和濕性两種,前者為感光細胞逐漸退化;後者比較嚴重,不正常的微血管在黃斑部底下生長,造成血或血清渗出,破坯黃斑導至中央视力快速喪失。

你有黃斑部退化症或視網膜病变嗎? 發現病變需要依赖詳細的眼睛檢查,陳照光医師診所有最先進的儀器如OCT光頻断層掃瞄儀(檢查眼底黃斑部狀況),髙解析度数碼眼底攝影器(顯示眼底病徵)及裂隙灯,來做精確的診斷。如果感覺有上述任何8種症狀,請來电預約時間,作詳細的眼睛檢查。
                        
阿氏網格 (Amsler Grid)—每日用它自我测試視力,及早發現視網膜問題: 测試方法:(测試前請勿忘戴上平常用來讀書的眼鏡) 將網格放在臉正前方l4英吋處 輪流测試,先用手蓋住一支眼睛, 另一眼直視網格中央的黑奌,不可斜望. 如果發覺網格有直線條看起來不直,呈波狀,或者線條部份不見了,或者有些小方格與其他方格不一樣大小,請立刻來看陳照光医師,因為你的黃斑可能有問题.
