[Retinal detachment due to macular holes in highly myopic eyes. Prognostic factors].
OBJECTIVE
To evaluate the prognostic value of axial length and epiretinal membrane (ERM) separation during vitrectomy for retinal detachment due to macular hole in high myopia.


METHODS
Thirty-two consecutive highly myopic eyes (31 patients) with retinal detachment due to a macular hole were retrospectivly studied. All eyes underwent pars plana vitrectomy with gas tamponade (C3F8). An epiretinal membrane was removed in 9 cases. The 32 cases were divided into 3 groups: anatomical success after the initial surgery (group 1, 15 cases); anatomical success after two surgical procedures without silicone oil (group 2, 5 cases), and silicone oil tamponade (group 3, 12 cases).


RESULTS
Retinal reattachment occurred in 15 cases (46.8%) after the initial surgery. The difference of axial length between the 3 groups was not significant. The rate of anatomical success without silicone oil was 88.8% (8/9 cases) when an ERM was peeled and the number of peelings was significantly higher (p=0,04) in group 1 than in group 3.


CONCLUSIONS
The axial length was not a pronostic factor of silicone oil tamponade in this study. The success rate was higher when an ERM was peeled. However, considering the technical difficulty in removing the ERM completely, gas tamponade seems to be the better initial treatment.
