Retinal dialyses cause slowly progressive retinal detachments occurring in young, emmetropic males with no history of preceding trauma. They originate at the ora errate and are asymptomatic until macular involvement occurs and are not associated with posterior vitreous detachment (PVD).  These retinal detachments can be successfully managed in the majority of cases with an external surgical approach in the form of cryotherapy and buckling without recourse to vitrectomy.  In contrast, giant retinal tears (GRTs) are found equally in both sexes and are associated with an abnormally anterior PVD that extends to the ora errate.  They are frequently associated with collagen disorders and may occur bilaterally in up to 80%. Management of GRTs necessitates vitrectomy and internal tamponade due to independent mobility of the posterior flap. Differentiation of these two distinct types of retinal detachment is therefore essential if optimal management is to be implemented. We present an interesting case of a retinal dialysis secondary to direct trauma in a 21-year-old, myopic (-1.75D) male.  The extensive oral break combined features of both retinal dialysis and GRT with avulsion of the pars plana epithelium, which was seen as an irregular ribbon within the vitreous cavity.  Independent mobility of the posterior flap precluded the standard external approach to retinal dialysis surgery and therefore a combination of both external buckling, vitrectomy and internal tamponade was employed. This case illustrates how the importance of careful preoperative assessment and the recognition of clinical signs, combined with an understanding of the pathological classification of rhegmatogenous retinal detachment enables the best chance of successful repair.
