Acute vision loss is a common emergency in ophthalmology. Prompt and accurate diagnosis and treatment are essential to restore or preserve vision. Abnormalities in any part of the visual pathway, from the refractive media to the occipital cortex, can cause vision loss. In this article, we present an emergency diagnostic and treatment plan for acute vision loss based on its etiology.

As a group of neurodegenerative disease with irreversibility and blindness, glaucoma is primarily evidenced by the deterioration of optic nerves and visual field impairments. With the continuous development of the aging population, the number of annual glaucoma patients in the world is increasing year by year and is expected to increase to 111.8 million by 2040. Minimally invasive glaucoma surgery (MIGS) has the advantages of light damage, few complications and good results. This article reviews the research progress in MIGS at home and abroad in recent years.
