Glaucoma is sometimes referred to as the “Silent Thief of Vision”, and if left untreated, is one of the leading causes of blindness in Canada. Glaucoma is associated with elevated intraocular pressure, which consequently puts strain and pressure on the optic nerve. This excessive pressure will lead to optic nerve tissue damage, which could cause gradual vision loss. The peripheral vision is typically affected first, however could eventually lead to central vision loss if no treatment is initiated.
眼压升高可能是由以下两个主要问题造成的：
- 眼内产生的液体过多，这种液体被称为房水。
- 眼内产生的液体无法通过小梁网有效排出。
因此，青光眼的初始治疗包括使用作用于这两个解剖结构的局部用药。有时也需要进行手术干预来控制眼内高压。.
检测和诊断青光眼的最佳方法是每年定期进行眼科检查。这样可以监测视神经健康状况，并测量眼压以确保其稳定。如果家族中有青光眼病史，进行青光眼筛查尤为重要。.
