Purpose:
This study aimed to assess the therapeutic effect of vitreous surgery in conjunction with photocoagulation for highly myopic retinal detachment resulting from a macular hole.
Methods:
Sixty-two consecutive highly myopic patients (65 eyes) with retinal detachment from macular holes underwent vitreous surgery. Gas tamponade in conjunction with laser photocoagulation was performed in 46 eyes (44 cases, group 1); gas tamponade only was performed in 12 eyes (11 cases, group 2); and silicone oil tamponade only was performed in seven eyes (seven cases, group 3). Additional laser photocoagulation was given in group 1 if necessary. The anatomical and functional success rates were compared between the groups.
Results:
Primary retinal reattachment was achieved in 43 eyes (93.5%) in group 1, seven eyes (58.3%) in group 2 and four eyes (57.1%) in group 3. Final visual acuity was 6/60 or more in 24 eyes (52.2%) in group 1, in six eyes (50.0%) in group 2 and in three eyes (42.9%) in group 3. The initial retinal reattachment rate was significantly higher in group 1 than in group 2 (P = 0.0075) and group 3 (P = 0.0248). The macular hole was completely closed in 18 eyes in group 1 and one eye in group 2 after 2 months or longer. A thin fibrous membrane and scar could be easily noticed beneath the macula in 15 eyes.
Conclusion:
Vitreous surgery in conjunction with laser photo-coagulation can improve the surgical success rate for highly myopic retinal detachment resulting from a macular hole.
