干眼睛

Overview

Dry eye is a chronic condition in which you do not produce enough tears to keep your eyes healthy and comfortable, or the quality of tears that you do produce has been compromised.

结果,你的眼睛可能会感到烦躁。您可能会遇到燃烧,略微痛苦或邋ans的感觉。对于许多人来说,干眼液温和,可以通过定期使用在柜台人工泪滴下进行处理。但有时症状可能会变得更加严重,使得每一天活动都很难。可能会感觉到你眼中有沙子,并且掉落可能是无效的。没有治疗,慢性干眼液可以导致感染和视力受损。如果您正在遇到干眼症的症状,轻度或严重,可以看到您的OCB眼科医生可以帮助您有效地管理干眼症状态。

什么导致干眼睛?

随着年龄的增长和女性更容易受到影响,干眼症的风险会增加。有助于干眼症的其他因素可包括长期隐形眼镜使用和屈光程序,例如LASIK,这可能导致撕裂产生降低。

当构成撕裂膜的不同部件的平衡变得偏移时,有时会发生干眼。

Your tear film contains essentially two layers: an oily outer layer that seals in and prevents evaporation of an inner layer that is a mixture of water and mucin. The water cleanses the eye and washes away foreign particles and the mucin enables the watery layer to spread evenly over the surface of the eye and helps the eye remain moist. Without mucin, tears would not stick to the eye. When there is a disruption in the balance of oil, water and mucin, dry spots develop.

分泌油的管道的炎症是这可能发生的一个原因。某些自身免疫疾病以炎症为特征,如狼疮和类风湿性关节炎会导致撕裂分泌减少。

A wide variety of common medications, both prescription and over-the-counter, can cause dry eye by reducing tear secretion. Be sure to tell your OCB eye doctor the names of all of the medications that you are taking.

Exposure to a dry, windy climate, as well as smoke and air conditioning, which can speed tear evaporation, can exasperate the symptoms of dry eye.

Symptoms & Diagnosis

干眼症症状可包括:

  • 刺痛或灼热的眼睛
  • 掠夺
  • 在眼睛或眼睛周围的粘性粘液
  • 过度的撕裂或无法产生泪水
  • Discomfort wearing contact lenses

您的OCB眼科医生可以诊断干眼症。除了注意到你的症状和使用缝隙灯来检查你的眼睛,他或她可能会使用称为ShirmeR撕裂测试的测试来测量撕裂生产。干眼也可以诊断出特殊染料滴。您的OCB眼科医生将这些滴剂放在眼睛中,并观察干燥点在角膜上发展需要多长时间。

Treatment

虽然没有治愈的干眼症,但治疗可以有效地保持控制症状。较早治疗干燥的眼睛,而不是以后可以帮助保持眼睛的健康,并减慢任何进一步的病症进展。

治疗通常涉及某种类型的人造泪滴在柜台上销售。一个可以具有更多的油组分,另一个可以是更多的水基。适用于你的工作取决于你的眼泪缺失的东西。您的OCB眼科医生可以帮助您确定最适合您的东西。如果您发现您需要每天使用人工泪滴超过四次,这可能意味着您需要切换到防腐剂人工泪滴或可能受益于药物下降以治疗干燥的眼睛。如果是这种情况,您的OCB眼科医生可以测试炎症的存在,干眼症的常见原因,并规定可能降低炎症的滴。

另一种帮助保持眼睛润滑的另一种选择是保护自己的眼泪。通常,你的眼泪通过鼻子里的小通道排出眼睛。您的OCB眼科医生可以执行暂时关闭渠道的程序。通过这种方法,插头插入撕开管道并阻挡眼睛的排水系统。

LipiFlow

眼睛的睑板腺产生的油密封n and prevent evaporation of your tear film. If your dry eye is caused by problems with these glands, your OCB eye doctor may recommend a new procedure called LipiFlow. Performed in the doctor’s office, this procedure delivers warm pulsations to the eyelids, opening up the oil glands and helping them to secrete oils normally.

你在家里可以做些什么

To minimize the evaporation of tears, avoid exposure to dust, cigarette smoke, other irritating pollutants and try to avoid the wind. You could also try these remedies:

每天两次涂抹一个温暖的压缩

温暖的压缩将有助于降低油的厚度,并使眼睑油将在冬季更好地流动并保护您的泪膜。

使用冷雾加湿器

每天在家里和工作场所使用加湿器以保持空气潮湿。

Avoid sleeping with your ceiling fan on

天花板粉丝将热水吹向你的眼睛。这对那些在睡觉时不完全闭合盖子的人来说尤其恼火。您的OCB眼科医生可以在晚上拨出软膏,帮助您有助于不完整的关闭。

眨眼更多

Blinking spreads tears evenly over the surface of your eye. When you watch TV, drive or stare at a computer screen, you typically blink half as often as normal. Taking breaks from these activities and trying to blink more often can be helpful.

增加你的欧米茄3脂肪酸摄入量。

Studies show that consistently eating foods rich in omega-3 fats, such as salmon and other fatty fish, and certain nuts and seeds such as walnuts, flaxseeds, or chia seeds help improve dry eye. You could also take a fish or flax seed oil supplement daily.
