A retinal fissure is a full-length split in the retina, like a tear in a garment. It is usually due to an area of degeneration in the retina and the formation of a fissure due to pulling of the vitreous. The formation of a retinal fissure is the result of the combined effect of two types of tissue degeneration: the retina and the vitreous. The predilection for middle-aged and elderly people, especially highly myopic patients, is related to the frequent degeneration of vitreous and retina in the elderly or highly myopic. 1.What are the symptoms of retinal fissure caused by myopia When a partial detachment of the retina occurs, the patient has a fixed cloud-like shadow in the visual field on the opposite side of the detachment. In case of macular detachment, there is a large and sharp decrease in central vision. Detachment is often preceded by aura symptoms, with flashes of light during eye movements. Due to vitreous clouding, there are often dark shadows floating in the visual field. If the retina is completely detached, vision is reduced to light perception or completely lost. There are also often visual distortions before the vision loss, and the sensation of object tremors during eye movements. 2.How to treat retinal fissure caused by myopia The fissure requires laser treatment within 24-72 hours, condensation or scleral buckling treatment and vitrectomy treatment as soon as possible depending on the size and location of the fissure. Treatment is based on the individual circumstances of each case.
