The progression of blindness due to ophthalmologic diseases may have different prognoses, for example, central retinal artery embolism may cause transient blurring of vision, and glaucoma may cause narrowing of the field of vision.
Many ophthalmic diseases may cause blindness in their terminal stages, and the prognosis varies with the type of disease.
Central retinal artery embolism may be preceded by vasospasm, resulting in transient blurred vision and other symptoms. It should be treated promptly with oral nitroglycerin and other medications to dilate the blood vessels and avoid embolism.
Glaucoma patients will have different precursor symptoms such as eye swelling and pain and narrowing of visual field before going blind, and they need to be treated by lowering the intraocular pressure to avoid blindness, such as ordering carteolol hydrochloride drops and brinzolamide drops in the eyes, or by doing composite trabeculectomy and other treatments.
Patients with ophthalmic diseases should go to the hospital in time, and be guided by the doctor after a clear diagnosis, so as to control the condition as soon as possible and avoid the development of blindness.
