Surgical Treatment of Idiopathic Macular Hole Using Different Types of Tamponades and Different Postoperative Positioning Regimens

Table 2

Macular hole closure success rates after primary surgery in each individual group.

	Group 1 (SF6 + nonsupine reading position) (%)	Group 2 (air + nonsupine reading position) (%)	Group 3 (air + prone position) (%)	Group 4 (SF6 + prone position) (%)
MH closure success of whole sample	100	56.0	84.6	92.6
MH closure success of IMH ≤ 400 µm	100	88.9	100	100
Successful closure of IMH > 400 µm	100	37.5	71.4	77.8
