Non-compressive retinal whitening is a grayish-white area of the peripheral retina that can be found in the absence of external pressure on the sclera. It occurs, primarily due to thinning of the peripheral retina, and is most commonly seen clinically in patients with high myopia, where excessive growth of the eye axis may lead to thinning of the peripheral retina by pulling. Non-compressive retinal whitening belongs to retinal degeneration, which is mainly observed in the clinic. Because the area of non-compaction retinal whitening is relatively stable in most patients, it does not require much treatment. However, if lattice-like degeneration or frost-like degeneration is found in the peripheral retina, retinal laser lasering needs to be carried out in time to avoid the occurrence of lesions such as retinal tears and retinal detachment.
