DVCE procedure. (a) Drainage. Puncture and drainage of the scleral wall corresponding to the highest point of the retinal bulge. (b) Injection of the viscoelastic agent. After supplying the subretinal fluid, a puncture was made 4 mm behind the limbus of the cornea and into the vitreous cavity to inject the viscoelastic agent for increasing intraocular pressure. (c) External pressure (explant). A suitable silicon sponge block or silicone tape was placed at the position of the hole.
