Clinical characteristics and surgical options: scleral buckling surgery subretinal fluid, some of the tear will tend to open more anti-retinal detachment higher than before the release, the closure of this break is difficult. This is the “fish-mouth” hole. Clinical features First, preoperative: According to the following typical features, can often be identified in the preoperative “fish mouth type” hole: Such holes often large horseshoe shape, the trailing edge curling, cover flap off; if the blood vessels Across the break may have vitreous hemorrhage; break often located in the equator and with spherical retinal detachment; from the hole to the posterior pole often a radial retinal folds; out of the range of serrated edge than the ciliary body flat Especially in the quadrant where the breach is located; disease often grows rapidly even with broken holes and the detachment located above. Indirect ophthalmic microsurgery retreats from the scrotal indentation because it does not
