APMPPE associated with adenovirusSPS Thomson and STD Roxburgh542Kaiser et al5 have described images of the vitreoretinalinterface in the context of a clinically evident TTPHshowing a partial posterior vitreous separation on OCT,apparently indicating vitreoretinal traction. Theyhypothesise that vitrectomy may be beneficial in thisgroup of patients because it relieves traction and allowsresolution of a shallow traction retinal detachment.Duguid et al8 and Patel et al7 have reported patients witha similar pattern on OCT without a clinically evidentTTPH. The patient that we present has responded well tovitrectomy. Preoperatively there was no clinicallydetectable TTPH, and OCT revealed a dome-shapedelevation with partial vitreoretinal separation (whitearrows), suggesting that this OCT pattern may be usefulin identifying patients who will potentially benefit fromsurgery regardless of the clinical appearance of thepremacular posterior hyaloid.Vitrectomy for macular oedema is not universallyefficacious, and further investigation is clearly requiredinto the efficacy of surgery in patients with DDMO. Weare currently conducting a randomised controlled trial toevaluate the benefit of surgery in such patients. This caseshows that patients with no clinical evidence of a TTPHmay achieve and sustain anatomical and visualimprovement following surgery. Further investigationinto the OCT vitreoretinal interface pattern as a potentialpredictor of surgical outcome is warranted.AcknowledgementProprietary interests: None.References1 Gandorfer A, Messmer EM, Ulbig MW, Kampik A.Resolution of diabetic macular edema after surgical removal
