<p>現時香港有超過70萬病人，患病5年以上的病人有20%-30%機會出現糖尿病視網膜病變。醫學界認為因體內血糖長期高造成血管內壁損害，紅血細胞聚集並失去變形能力，以至血流減慢，毛細血管阻塞，引起視網膜缺血、缺氧，因而導致糖尿病視網膜病變。</p>





<h2 class="wp-block-heading" id="h-4">糖尿病視網膜病變4個階段</h2>



<figure class="wp-block-image size-large"><img decoding="async" loading="lazy" width="1000" height="667" src="https://metrohealthplus.hk/wp-content/uploads/2022/07/close-up-woman-hands-using-glucose-meter-finger-check-blood-sugar-level.jpg" alt="" class="wp-image-59005" srcset="https://metrohealthplus.hk/wp-content/uploads/2022/07/close-up-woman-hands-using-glucose-meter-finger-check-blood-sugar-level.jpg 1000w, https://metrohealthplus.hk/wp-content/uploads/2022/07/close-up-woman-hands-using-glucose-meter-finger-check-blood-sugar-level-300x200.jpg 300w, https://metrohealthplus.hk/wp-content/uploads/2022/07/close-up-woman-hands-using-glucose-meter-finger-check-blood-sugar-level-768x512.jpg 768w" sizes="(max-width: 1000px) 100vw, 1000px" /></figure>



<p>糖尿病性視網膜病變主要有四個階段：</p>



<p>1. 輕度非增殖性視網膜病變：<br>在這個最初階段，微血管瘤發生，它們是小面積的氣球樣腫脹視網膜的小血管。</p>



<p>2. 中度非增殖性視網膜病變：<br>隨著病情的發展，一些血管滋養視網膜被封鎖。</p>



<p><a href="https://bit.ly/3doYyXk"><strong><span class="has-inline-color has-luminous-vivid-orange-color">想預防糖尿上眼？ 糖友護眼須知</span></strong></a></p>





<p>3. 嚴重非增殖性視網膜病變：<br>許多血管阻塞，使一些地區的視網膜血液供應減少，引致視網膜缺氧。這些領域的視網膜發出信號，生長新血管，提供營養。</p>



<p>4. 增殖性視網膜病變：<br>這是最晚期糖尿病視網膜病變，如視網膜血液供應受到損害。該信號發出的視網膜營養觸發新血管生長。<br>新生之微血管會在視網膜表層增生，這些新的血管異常脆弱及增生紊亂，很容易出血，嚴重會使視力喪失，甚至可能導致失明；再加上其出現可帶有纖維細胞，可令視網膜纖維化，此種病變：<br>&#8211; 可導致玻璃狀體出血，使視力模糊<br>&#8211; 可導致繼發性視網膜脫落<br>&#8211; 可導致繼發性青光眼</p>

<h2 class="wp-block-heading"><strong><strong><strong><strong><strong>5大徵兆發現視力開始出現問題</strong></strong></strong></strong></strong></h2>

<p>糖尿上眼令視力開始惡化，影響日常生活。糖尿病患者可觀察自己是否出現以下5個徵兆，如有以下情況發生，請盡快去檢查視力。</p>





<h2 class="wp-block-heading" id="h-1">1. 眼前有黑點飄動</h2>



<figure class="wp-block-image size-large"><img decoding="async" loading="lazy" width="1000" height="667" src="https://metrohealthplus.hk/wp-content/uploads/2022/07/little-girl-covering-eyes-with-hands-t-shirt-looking-sleepy-front-view.jpg" alt="" class="wp-image-59009" srcset="https://metrohealthplus.hk/wp-content/uploads/2022/07/little-girl-covering-eyes-with-hands-t-shirt-looking-sleepy-front-view.jpg 1000w, https://metrohealthplus.hk/wp-content/uploads/2022/07/little-girl-covering-eyes-with-hands-t-shirt-looking-sleepy-front-view-300x200.jpg 300w, https://metrohealthplus.hk/wp-content/uploads/2022/07/little-girl-covering-eyes-with-hands-t-shirt-looking-sleepy-front-view-768x512.jpg 768w" sizes="(max-width: 1000px) 100vw, 1000px" /></figure>



<p>視野中，看到有一些移動物體，侈如小黑點﹑小蟲狀﹑塵埃等，這些都是「飛蚊症」的現象，由於眼波內的玻璃體弱化導致的。</p>



<p><a href="https://bit.ly/3doYyXk"><strong><span class="has-inline-color has-luminous-vivid-orange-color">想預防糖尿上眼？ 糖友護眼須知</span></strong></a></p>





<h2 class="wp-block-heading" id="h-2">2. 視力模糊</h2>

<p>視網膜是水晶體聚焦處，透過眼睛看到的訊息經由視神經傳送至腦部，當血管液體的釋出破壞或在網膜上結痂，傳送至腦部的影像就會變得模糊。</p>





<h2 class="wp-block-heading" id="h-3">3. 視野缺損</h2>



<figure class="wp-block-image size-large"><img decoding="async" loading="lazy" width="1000" height="667" src="https://metrohealthplus.hk/wp-content/uploads/2022/07/eye-strain-can-be-caused-by-disease-that-is-due-underlying-disease-such-as-rubbing-your-eyes-looking-screens-long-periods-time-wearing-glasses-with-incorrect-vision-values.jpg" alt="" class="wp-image-59011" srcset="https://metrohealthplus.hk/wp-content/uploads/2022/07/eye-strain-can-be-caused-by-disease-that-is-due-underlying-disease-such-as-rubbing-your-eyes-looking-screens-long-periods-time-wearing-glasses-with-incorrect-vision-values.jpg 1000w, https://metrohealthplus.hk/wp-content/uploads/2022/07/eye-strain-can-be-caused-by-disease-that-is-due-underlying-disease-such-as-rubbing-your-eyes-looking-screens-long-periods-time-wearing-glasses-with-incorrect-vision-values-300x200.jpg 300w, https://metrohealthplus.hk/wp-content/uploads/2022/07/eye-strain-can-be-caused-by-disease-that-is-due-underlying-disease-such-as-rubbing-your-eyes-looking-screens-long-periods-time-wearing-glasses-with-incorrect-vision-values-768x512.jpg 768w" sizes="(max-width: 1000px) 100vw, 1000px" /></figure>



<p>眼睛能看到的範圍比以前明顯縮，這是視網膜剝受損及黃斑部病變時，會出現中心視力驟降、視物變形或水波樣感，出現視野缺損。</p>



<p><a href="https://bit.ly/3doYyXk"><strong><span class="has-inline-color has-luminous-vivid-orange-color">想預防糖尿上眼？ 糖友護眼須知</span></strong></a></p>





<h2 class="wp-block-heading" id="h-4-1">4. 畏光</h2>



<figure class="wp-block-image size-large"><img decoding="async" loading="lazy" width="1000" height="667" src="https://metrohealthplus.hk/wp-content/uploads/2022/07/elderly-woman-uses-her-hand-massage-her-eyes-due-fatigue-have-blurred-vision.jpg" alt="" class="wp-image-59013" srcset="https://metrohealthplus.hk/wp-content/uploads/2022/07/elderly-woman-uses-her-hand-massage-her-eyes-due-fatigue-have-blurred-vision.jpg 1000w, https://metrohealthplus.hk/wp-content/uploads/2022/07/elderly-woman-uses-her-hand-massage-her-eyes-due-fatigue-have-blurred-vision-300x200.jpg 300w, https://metrohealthplus.hk/wp-content/uploads/2022/07/elderly-woman-uses-her-hand-massage-her-eyes-due-fatigue-have-blurred-vision-768x512.jpg 768w" sizes="(max-width: 1000px) 100vw, 1000px" /></figure>



<p>眼睛容易對燈光敏感，接觸到強光時更出現刺痛感。</p>





<h2 class="wp-block-heading" id="h-5">5. 出現重影</h2>



<figure class="wp-block-image size-large"><img decoding="async" loading="lazy" width="1000" height="667" src="https://metrohealthplus.hk/wp-content/uploads/2022/07/window-reflected-office-table.jpg" alt="" class="wp-image-59015" srcset="https://metrohealthplus.hk/wp-content/uploads/2022/07/window-reflected-office-table.jpg 1000w, https://metrohealthplus.hk/wp-content/uploads/2022/07/window-reflected-office-table-300x200.jpg 300w, https://metrohealthplus.hk/wp-content/uploads/2022/07/window-reflected-office-table-768x512.jpg 768w" sizes="(max-width: 1000px) 100vw, 1000px" /></figure>



<p>重影多數是由眼部疾病引起的。</p>
