Result

Kim et al., 2014

91

Retrospective, interventional

Intravitreal anti-VEGF

1.38 (0.53)

0.96 (0.65), 6 months

Beneficial

Iacono et al., 2014

23

Prospective, interventional

Intravitreal anti-VEGF

0.82 (0.22)

0.68 (0.41), 12 months

Beneficial

Shin et al., 2015

82

Retrospective, comparative, interventional

(1) Intravitreal anti-VEGF

1.21 (0.71)

0.76 (0.59), 6 months

Both are beneficial. Combination therapy was better in thick submacular hemorrhage.

(2) Intravitreal anti-VEGF with pneumatic displacement

1.14 (0.63)

0.94 (0.61), 6 months

Cho et al., 2015

93

Retrospective, comparative, interventional

(1) Intravitreal anti-VEGF

1.18 (0.57)

0.96 (0.39), 12 months

Both are beneficial. No difference between them

(2) Intravitreal anti-VEGF with pneumatic displacement

1.20 (0.74)

0.95 (0.48), 12 months

Kitagawa et al., 2016

20

Prospective, interventional

Intravitreal t-PA, anti-VEGF, and gas tamponade

0.66 (0.40)

0.42 (0.45), 6 months

Beneficial

Kadonosono et al., 2015

13

Prospective, interventional

Subretinal surgery with t-PA and gas tamponade

1.21 (0.44)

0.70 (0.33), 3 months

Beneficial

Chang et al., 2014

101

Retrospective, comparative, interventional

(1) Subretinal surgery with t-PA, gas tamponade, and intravitreal anti-VEGF

1.92 (N/A)

1.74 (N/A), 6 months

Both are beneficial. Anti-VEGF may help maintain the visual acuity gains.

(2) Subretinal surgery with t-PA, gas tamponade

2.26 (N/A)

1.54 (N/A), 6 months

Jong et al., 2016

24

Prospective, comparative, interventional

(1) Intravitreal t-PA, anti-VEGF, and gas tamponade

0.91 (N/A)

0.63 (N/A), 12 weeks

Both are beneficial. No difference between them

(2) Subretinal surgery with t-PA, gas tamponade, and intravitreal anti-VEGF

0.75 (N/A)

0.72 (N/A), 12 weeks

Current study

236

Retrospective, comparative, interventional

(1) Observation

1.57 (0.74)

1.39 (0.84), 12 months

No differences among 4 treatment strageis. Intravitreal Anti-VEGF helped with visual recovery in the short term.

(2) Intravitreal anti-VEGF

1.09 (0.70)

0.90 (0.83), 12 months

(3) Intravitrea gas tamponade(± anti-VEGF or t-PA)

1.31 (0.83)

1.35 (0.88), 12 months

(4) Subretinal surgery with t-PA, gas tamponade (± anti-VEGF)

1.62 (0.77)

1.44 (0.91), 12 months

  1. LogMAR, logarithm of minimum angle resolution; SD, standard deviation; VEGF, vascular endothelial growth factor; t-PA, tissue plasminogen activator.
