Cystoid macular oedema (CMO) is a major cause of reduced vision following intraocular surgery. Although the aetiology of CMO is not completely clarified, intraocular inflammation is known to play a major role in its development. The macula may develop cytotoxic oedema when the primary lesion and fluid accumulation occur in the parenchymatous cells (intracellular oedema) or vasogenic oedema when the primary defect occurs in the blood-retinal barrier and leads to extracellular fluid accumulation (extracellular oedema). We report on the mechanisms of CMO formation after pars plana vitrectomy and associated surgical procedures and discuss possible therapeutic approaches.

IntroductionDiabetic retinopathy (DR) is the main cause of adult visual impairment worldwide. Severe non-proliferative DR (sNPDR) is an important clinical intervention stage. Currently, panretinal photocoagulation (PRP) is the standard treatment for sNPDR. However, PRP alone cannot completely prevent NPDR progression. One explanation might be that PRP does not remove the detrimental vitreous that plays an important role in DR progression. Microinvasive pars plana vitrectomy (PPV) was shown to be a safe and effective method to treat late-stage proliferative DR (PDR) by completely removing the pathological vitreous. However, whether PPV is effective in controlling sNPDR remains unknown. In this trial, we aim to compare the effectiveness of microinvasive PPV with that of PRP for sNPDR progression control.Methods and analysisThis single centre, parallel group, randomised controlled trial aims to evaluate the clinical efficacy of microinvasive PPV in preventing the progression of sNPDR compared with PRP. A total of 272 adults diagnosed with sNPDR will be randomised 1:1 to the microinvasive PPV and PRP groups. The primary outcome is the disease progression rate, calculated as the rate of sNPDR progressed to PDR from baseline to 12 months after treatment. The secondary outcomes include the change in best-corrected visual acuity, re-treatment rate, diabetic macular oedema occurrence, change in central retinal thickness, change in the visual field, cataract occurrence and change in the quality of life.Ethics and disseminationThe Ethics Committee of Zhongshan Ophthalmic Center approved this study (2019KYPJ108). The results will be presented at scientific meetings and submitted for publication to peer-reviewed journals.Trial registration numberNCT04103671.

AbstractMacular surgery has become an increasingly atraumatic procedure for the eye with the surgical methods that have been further developed in recent years. The most common complications include cystoid macular oedema and retinal detachment, more rarely endophthalmitis. The aim of this retrospective study is to record the number of retinal detachments following elective macular surgery. In this study we included all patients who underwent pars plana vitrectomy (ppV, 20 or 25 gauge) in the years 2009 – 2016. We then identified the patients who were hospitalised again because of retinal detachment. For the affected patients, the rate of retinal detachment, functional outcomes and possible risk factors were recorded. A total of 904 eyes were identified, of which 667 had surgery for epiretinal membrane, 188 for macular hole, and 49 for vitreomacular traction with a 20 or 25 gauge ppV. Of these 904, retinal detachment occurred in 17 (1.88%) cases. The mean time between first ppV and second ppV with retinal detachment was 248 days (3 – 1837 days). Two of the 17 patients had at least one retinal break before or during surgery. The retinal break was located inferior in six cases, superior in four; in four cases PVR retinal detachment and in three cases the foramina were distributed. Mean visual acuity was 0.27 (decimal) before macular surgery and 0.28 at the time of last presentation. Modern vitrectomy techniques reduce the complications in elective macular surgery, but do not replace the surgeonʼs experience.
