Vitreous liquefaction retinal detachment should be treated immediately. Commonly used treatments include surgery and conservative treatment. 1. Surgery: The vitreous base is tightly adhered to the retina, and in the process of liquefaction, the area is easy to pull and produce retinal cracks or macular cracks, vitreomacular pulling syndrome, etc. Once the vitreous fluid drills into the subretina, it will cause subretinal fluid accumulation, proliferation, and detachment of retina. Once the crack is produced, the vitreous fluid will drill into the subretina, resulting in subretinal fluid accumulation, proliferation, and large retinal detachment, which requires vitrectomy surgery. 2. Conservative treatment: vitreous liquefaction is common among the elderly and highly myopic people. If complete posterior vitreous detachment occurs after liquefaction, the retinal pulling force will be weakened, and the fissure can be observed and followed up on a regular basis, and the fissure has the possibility of spontaneous closure. Medical attention should be sought as soon as occlusion of vision and loss of vision occurs. Retinal detachment caused by vitreous liquefaction should seek immediate medical attention to examine the retina, and treatment is mainly surgical.
