The following were performed before the OCT scanning: (1) evaluation of refractive error without pupil dilation by optometry (AR-310A, NIDEK, Japan); (2) axial length measurement by IOLMaster (Carl Zeiss Meditec AG, Germany); (3) intraocular pressure measurement by noncontact tonometer (TX-20, Canon, Japan); (4) color fundus photography (retinal camera CR-DGi, Canon, Japan); (5) ultrasonography of the eye ball to exclude posterior staphyloma (B-scan CineScan, Quantel Medical, France); and (6) careful examination of the peripheral retina by a senior retinal specialist (Fenghua Wang) using an indirect ophthalmoscope to exclude peripheral degeneration, retinal tear, or retinal detachment.
showed significant associations between choroidal thickness, SE, CT, and posterior staphyloma height but not AL.19 The tessellated group in a study by Wang et al.
In this study, we present the outcomes of PPV, ILM peeling, MB, and perfluoropropane (C3F8) gas tamponade performed to treat MHRD in a patient with high myopia and posterior staphyloma.
On fundus examination, bilateral posterior staphyloma with myopic degenerative changes were observed, as well as a shallow RD associated with the posterior staphyloma in the right eye.
(8,9,10) However, although PPV with ILM peeling and gas tamponade is the primary surgical approach for such cases, it may not be adequate to address certain pathophysiological factors such as the tension created by the posterior staphyloma. The presence of posterior staphyloma in these patients may lead to complications such as foveoschisis, foveal detachment, and MHRD.
(14,15) These high rates of reported anatomical success in high-myopic MHRD patients have led to MB gaining prominence, especially when treating patients with posterior staphyloma.

Highly myopic eyes are often accompanied by pathologic fundus changes, such as posterior pole chorioretinal atrophy and posterior staphyloma [2].
All the recurrent cases had open MH, high myopia more than 12 diopters, and posterior staphyloma.
Silicone oil reinjection is a simple technique and can be done by all vitreoretinal surgeons but it has the disadvantages of the possibility of recurrent RD after silicone oil removal (especially in the presence of high myopia, posterior staphyloma, and open and large macular hole) and complications may occur as emulsification of silicone oil and increase of intraocular pressure.
We found that the risk factors for Re RD were open flat holes, high myopia, and posterior staphyloma. Five of the recurrent cases had a resurgery and silicone oil reinjection.
Most common abnormality was retinal detachment (39%), followed by vitreous opacities (31%), eye ball size abnormalities (12%), intraocular foreign body (4%), posterior staphyloma (3%) and retinal detachment with vitreous opacities (2%).
