Retinospasm mostly refers to retinal vasospasm, which occurs mainly because patients have pathologies such as hypertension, diabetes mellitus, hyperlipidemia, or because of high intraocular pressure. Retinal spasm can lead to transient ischemia and hypoxia in the retina, and patients may show transient visual impairment. Hypertension, diabetes mellitus, hyperlipidemia and other pathologies can lead to atherosclerosis of the blood vessels and insufficient blood supply to the cerebral blood vessels, which can manifest as retinal vasospasm in the early stages. High intraocular pressure is likely to affect retinal perfusion, leading to retinal vasospasm. Once retinal vasospasm occurs, it is necessary to consult a doctor in time and follow the doctor’s instructions.
