Conclusions-The wide range in OCT appearance of macular holes and associated prefoveal opacities suggests that, in at least some cases, a significant amount of retinal tissue is torn from the foveal area during macular hole formation. OCT imaging provides additional information on macular hole pathogenesis and is valuable in the planning of surgical intervention.

Aims-To determine whether it is necessary to support inferior retinal breaks with a scleral explant during pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RD). Methods-A prospective study was carried out on nine eyes of nine consecutive patients undergoing PPV for primary RD with associated inferior retinal breaks and no significant proliferative vitreoretinopathy. Results-Eight eyes were successfully reattached with a single operation. No cases presented with redetachment because of failed closure of the original inferior breaks. Conclusions-It is not necessary to support inferior retinal breaks with a scleral explant during PPV for primary RD repair in selected cases. (Br J Ophthalmol 2001;85:480-482) The use of pars plana vitrectomy (PPV) in the treatment of rhegmatogenous retinal detachment (RD) has gained increasing popularity over the past 20 years and is often combined with the use of a scleral explant.
