UBM-guided scleral buckling for Schwartz-Matsuo syndrome with tear of nonpigmented epithelium of the ciliary body: a case report.

Tear of the nonpigmented epithelium of the ciliary body is a rare condition associated with Schwartz-Matsuo syndrome. UBM plays a key role in detecting occult tears of the nonpigmented epithelium of the ciliary body, guiding scleral buckling surgery, and observing the closure of the tear postoperatively.
