Abstract

Purpose : To investigate outcome of proliferative vitreoretinopathy PVR associated retinal detachment repair between patients using conventional pars-plana vitrectomy PPV alone and using endoscopy assisted PPV

Methods : This is a retrospective cohort study. Medical records of patients who had PVR associated retinal detachment repair since 2009 were reviewed. Inclusion criteria include retinal detachment with PVR. Exclusion criteria include abscence of PVR, and non-compliance with postoperative follow up. Data collection included gender, previous retina surgeries, intraocular pressure (IOP), macula status on presentation (attached or detached), type of surgery performed (PPV alone or endoscopy assisted PPV), PVR location (anterior or posterior to the equator), number of retinectomy quadrants, anatomical outcome and IOP at one year

Results : 69 patients met the inclusion criteria. 43 patients had conventional PPV (16 females, 27 males), and 26 patients under went endoscopy assisted PPV (8 females, 18 males). In the PPV only group, 25 patients remained attached at one year follow up (success rate 58.2%). In the endoscopy assisted group, 17 patients remained attached at one year (success rate 65.4%), there was no significant difference between both groups outcome at 1 year (p value=0.55). Multifactorial logistic regression analysis of 1 year results showed an odd ratio of 4.5 (p-value= 0.012) with number of previous retina surgeries. Mean IOP on presentation was 10.7±0.7 mmHg in the PPV group, and 10.6±1.1 mmHg in the endoscopy group (p value= 0.95, CI 95%). When retina remained attached at 1 year, regression analysis showed a 0.49 correlation between preoperative and final IOP (p value= 0.005)

Conclusions : Endoscopy assisted pars-plana vitrectomy may have surgical advantages and facilitate treating hard to visualize anteriorly located PVR lesions. In this retrospective study, number of previous retina surgeries showed a statistically significant odd ratio with the anatomical success at the one year. Furthermore, in this sample, IOP measurement on presentation may help predict IOP outcome at 1 year point when retina remains attached. Further studies are warranted to help interpret the role of endoscopy in PVR associated retinal detachments
