Abstract Background To evaluate the rate, risk factors, functional outcome and prognosis in eyes with retinal detachment after post-operative endophthalmitis treated with 23G Pars Plana Vitrectomy. Methods Electronic patient files from 2009 until 2018 were screened for the presence of an endophthalmitis. Included were 116 eyes of 116 patients. This population was evaluated for the rate of retinal detachment after 23G Pars Plana Vitrectomy for endophthalmitis following cataract surgery or intravitreal injection. The main outcome measures were retinal detachment and visual acuity. Results The reasons for endophthalmitis were previous cataract surgery in 78 patients and following intravitreal injection in 38 patients. The first clinical evidence of endophthalmitis was present in median 5 days after the triggering intervention. Twenty-five eyes (21.55%) developed a retinal detachment an average of 25 days after endophthalmitis. RD is significantly associated with preoperative visual acuity (p = 0.001). Conclusions We emphasize the prognostic role of preoperative visual acuity in RD development of the endophthalmitis treated with 23G Pars Plana Vitrectomy.

Conclusions Modern 23G vitrectomy technique seems not to lower the rate of retinal detachment after vitrectomy for endophthalmitis. And we also emphasize the prognostic role of preoperative visual acuity in RD development of the endophthalmitis treated with 23G pars plana vitrectomy.

Purpose To report on the use of perfluorohexyloctane as a heavy liquid to temporarily tamponade the fovea for the prevention of recurrent massive subfoveal hemorrhage in patients with exudative age-related macular degeneration (ARMD). Methods The case series comprised seven patients with acute massive subfoveal hemorrhage due to exudative ARMD. The patients underwent pars plana vitrectomy, drainage of the subretinal blood, and foveal endotamponade with perfluorohexyloctane. The perfluorohexyloctane was removed 80.4 ± 38.1 days (median 98 days; range 22–118 days) after the primary surgery in a second pars plana intervention. Results In six patients (85.7%) the subretinal hemorrhage removed during the first pars plana vitrectomy did not recur after removal of perfluorohexyloctane. In the seventh, however, a subretinal hemorrhage re-developed five days after release of perfluorohexyloctane. No large epiretinal membranes were observed. In six eyes (85.7%), the retina remained attached after removal of perfluorohexyloctane but in one eye proliferative vitreoretinopathy developed, with central retinal detachment. After the first pars plana vitrectomy, visual acuity increased slightly but not significantly (p=0.25), from 0.03 ± 0.03 to 0.05 ± 0.07. Intraocular pressure rose from 15.0 ± 1.9 mm Hg to 24.9 ± 16.9 mm Hg. After a follow-up of 69.7 ± 121.0 days after removal of the perfluorohexyloctane, final visual acuity was 0.02 ± 0.04. Conclusions Perfluorohexyloctane may be a useful additional tool for preventing the recurrence of subfoveal re-bleeding in exudative ARMD.

Abstract Purpose The purpose of this study is to report the safety and efficacy of pars plana glaucoma drainage devices with pars plana vitrectomy using one of the vitrectomy sclerotomy sites for tube placement in patients with refractory glaucoma. Methods Retrospective case series of 28 eyes of 28 patients who underwent combined pars plana glaucoma drainage device and pars plana vitrectomy between November 2016 and September 2019 at Massachusetts Eye and Ear. Main outcome measures were intraocular pressure (IOP), glaucoma medication burden, best corrected visual acuity, and complications. Statistical tests were performed with R and included Kaplan-Meier analyses, Wilcoxon paired signed-rank tests, and Fisher tests. Results Mean IOP decreased from 22.8 mmHg to 11.8 mmHg at 1.5 years (p = 0.002), and mean medication burden decreased from 4.3 to 2.1 at 1.5 years (p = 0.004). Both IOP and medication burden were significantly lower at all follow-up time points. The probability of achieving 5 < IOP ≤ 18 mmHg with at least 20% IOP reduction from preoperative levels was 86.4% at 1 year and 59.8% at 1.5 years. At their last visit, three eyes (10.7%) achieved complete success with IOP reduction as above without medications, and 14 eyes (50.0%) achieved qualified success with medications. Hypotony was observed in 1 eye (3.6%) prior to 3 months postoperatively and 0 eyes after 3 months. Visual acuity was unchanged or improved in 23 eyes (82.1%) at their last follow-up. Two patients had a visual acuity decrease of > 2 lines. Two eyes required subsequent pars plana vitrectomies for tube obstruction, and one eye had transient hypotony. Conclusions The results of pars plana glaucoma drainage device and pars plana vitrectomy using one of the vitrectomy sclerotomy sites for tube placement are promising, resulting in significant IOP and medication-burden reductions through postoperative year 1.5 without additional risk of postoperative complications. Inserting glaucoma drainage devices into an existing vitrectomy sclerotomy site may potentially save surgical time by obviating the need to create another sclerotomy for tube placement and suture one of the vitrectomy ports.

Purpose. We aimed at reminding that X-linked retinoschisis may also be seen in female patients and share our vitreoretinal surgical experience. Methods. The patient underwent pars plana vitrectomy including the closure of the macular holes with inverted ILM flap technique bilaterally. Lens extractions were performed by phacoemulsification during the removal of silicone oil endotamponade. Patient. An 18-year-old girl with X-linked retinoschisis and large macular holes in both eyes presented to the clinic of ophthalmology. It was confirmed that the patient had RS1 mutation Results. Nine-month-follow-up was uneventful for retinal findings. Significant improvement in visual acuity was achieved, and macular holes were remained closed. Conclusion. In cases with large macular holes due to XLR, an inverted ILM flap technique might be safe and effective. Four-month-silicone-endotamponade might be sufficient.

The present paper reports our first results after pars plana vitrectomy in patients with diabetic retinopathy and hemodialysis with a follow-up of 6 to 24 months. Between January 1992 and October 1994 we performed vitreoretinal surgery with silicone oil tamponade in nine eyes of seven patients with diabetic nephropathy on hemodialysis. All patients had had type I diabetes for 19–32 years. Over the observation period the retina was completely attached in eight eyes. Final visual acuity of 0.1 - 0.7 was attained in four eyes, 0.06 two, hand movements in one eye. Two eyes had no useful final visual acuity because of redetachment of the retina or secondary glaucoma with rubeosis iridis. The small number of complications shows that pars plana vitrectomy can be done in diabetic patients with nephropathy on hemodialysis. This significantly improves their quality of life

Purpose. To evaluate visual outcomes and identify prognostic factors after pars plana vitrectomy (PPV) surgery for traumatic endophthalmitis. Methods. Medical records of 121 consecutive patients (121 eyes) diagnosed with traumatic endophthalmitis that had undergone pars plana vitrectomy were retrospectively reviewed. Results. 121 patients, aged from 6 to 71 years, all underwent PPV surgery. 113 cases had improved best corrected visual acuity (BCVA) after surgery and 60% of them obtained BCVA better than fingers counting (FC). Good final visual prognosis was significantly associated with time between trauma and initial treatment less than 12 hrs (40% versus 98%; P<0.001), time between trauma and PPV treatment less than 24 hrs (62% versus 98%; P<0.001), laceration length less than 10 mm (63% versus 96%; P<0.001), and presenting VA better than LP (42% versus 96%; P<0.001), while gender, type of laceration, presence of IOFB or retinal detachment, and the use of silicone oil tamponade were not significant factors resulting in better BCVA. Bacteria were identified in 43.8% of specimens and most of the microorganisms were identified as nonvirulent ones. Conclusions. Pars plana vitrectomy surgery was preferred as a primary treatment option for traumatic endophthalmitis. A good final visual prognosis was significantly associated with timely treatment, prompt vitrectomy surgery, shorter length of laceration, and better presenting visual acuity.

Purpose: Lasers can be sight damaging, because they can produce severe and permanent retinal damage. Methods: This paper reports two cases of subinternal limiting membrane (sub-ILM) hemorrhage related to laser exposure. Results: The first patient was only observed for the reason that the retinal localization was extramacular; for the second patient, we decided to perform ultraspeed (7500 cuts per minute) 27-gauge pars plana vitrectomy (PPV) because of the foveal position of the hemorrhage and because of the nonimprovement of his clinical condition. The first patient recovered 20/20 Snellen after 10 days without intervention, whereas the second patient recovered 15/20 Snellen the day after surgery; 15 days later, his visual acuity was 20/20 Snellen. Conclusions: Sub-ILM hemorrhage after exposure to lasers can be treated using an ultraspeed 27-gauge PPV. This tool can be considered safe and effective on non–self-resolving sub-ILM hemorrhage.
