The leading causes of visual impairment in North Americans are age-related, but appropriate care can preserve useful vision for most older adults. Cataract surgery is highly successful. Early detection and treatment of glaucoma can prevent vision loss. Laser treatment is remarkably effective against diabetic retinopathy. Vision loss due to macular degeneration cannot be delayed in all patients, but low-vision rehabilitation can maximize the usefulness of remaining sight.
北美视力障碍的主要原因与年龄相关,但适当的护理可以为大多数老年人保留有用的视力。白内障手术非常成功。青光眼的早期检测和治疗可以预防视力丧失。激光治疗对糖尿病性视网膜病变非常有效。并非所有黄斑变性导致的视力丧失都能延缓,但低视力康复可以最大限度地提高剩余视力的效用。
