To determine the results of pars plana vitrectomy and silicone oil tamponade to treat retinal detachment caused by macular holes in highly myopic eyes.

Eighteen highly myopic patients with spontaneous retinal detachment due to macular holes underwent vitrectomy and primary silicone oil tamponade. Preoperative statuses and postoperative results were reviewed. All patients had high myopia with axial lengths longer than 28 mm or had definite staphyloma. The average follow-up period was 24 months.

Successful retinal attachment of the retina was achieved in 17 eyes, though 1 eye had redetached. Of the 17 eyes, 13 eyes achieved anatomical macular hole closure and 7 eyes showed improved visual acuity.

Vitrectomy and silicone oil tamponade for retinal detachment due to macular holes in highly myopic eyes produce good anatomical and functional results.
