Which of the following is a non-surgical treatment for retinal detachment?

Retinal detachment is a serious condition that necessitates prompt treatment to prevent permanent vision loss. Among the non-surgical treatments available, cryosurgery is designed to treat certain types of retinal detachments. It involves applying extreme cold to the area of the retina that has detached, creating a scar that helps to reattach the retina to the underlying tissue.

While scleral buckling is also a treatment for retinal detachment, it is considered a surgical procedure as it involves the placement of a band on the outside of the eye to support the detached retina. Cataract surgery does not address the detachment itself and is unrelated to its treatment. Retinal laser therapy, although often used in conjunction with other treatments for retinal issues, is typically a surgical intervention aimed at preventing further detachment rather than treating an existing detachment directly.

Thus, cryosurgery stands out as a recognized non-surgical option for managing retinal detachment by promoting the reattachment of the retina through non-invasive means.
