Purpose. To determine the feasibility of using 25-gauge microincision vitrectomy surgery (25GMIVS) to treat vitreoretinal disease in glaucomatous eyes which have previously undergone trabeculectomy (TLE).Methods. A consecutive, interventional case series. We performed 25GMIVS in 15 glaucomatous eyes that had undergone TLE. Follow-up period was 11.5 months.Results. 25GMIVS was successfully used and led to improvement in visual acuity (P<0.01). We performed 25GMIVS for proliferative diabetic retinopathy with neovascular glaucoma in 53% of eyes (8 of 15). Although 3 eyes needed further TLE following 25GMIVS, final IOP was below 21 mmHg in all eyes except one eye (93%) and was comparable to pre-25GMIVS IOP (P=0.20) without an increase in the number of glaucoma medications (P=0.14).Conclusions. 25GMIVS is a feasible treatment for vitreoretinal disease in eyes with preexisting TLE, effective in both significantly improving BCVA and preserving the filtering bleb, while not excluding further glaucoma surgery.

Filtration Device

Background: The prognosis of conventional filtration surgery in eyes with neovascular glaucoma (NVG) is limited due to increased fibrovascular proliferation or bleeding. This study aims to evaluate the safety and efficacy of the EX-PRESS filtration device in the management of NVG associated with proliferative diabetic retinopathy (PDR). Methods: In this retrospective case series, we reviewed the medical records of patients diagnosed as having NVG associated with PDR who underwent EX-PRESS filtration surgery. The main outcome measures were: postoperative intraocular pressure (IOP), the percent of IOP drop, the number of glaucoma medications, visual acuity, and complications of surgery. Successful surgery was defined as an IOP <22 mm Hg and >5 mm Hg with or without additional glaucoma surgery, and no loss of light perception or less than a 2-line decrease on the Snellen chart of the best corrected visual acuity (BCVA). Results: Five patients (5 eyes) were included in this study. The mean preoperative IOP was 33.4 ± 5.9 mm Hg compared to an IOP of 17.0 ± 3.0 mm Hg at the last follow-up (p = 0.003). The mean number of preoperative anti-glaucoma medications was 3.8 ± 0.4 compared to 2.2 ± 1.5 (p = 0.06) at the last follow-up visit. Final visual acuity improved or stabilized within 1 Snellen line in all 5 patients. Three patients had a “hypertensive phase” (defined as an IOP >21 mm Hg during the first 6 postoperative months) which resolved within 2 months. Two patients developed a hyphema that resolved spontaneously. None of the patients experienced any serious complications. Conclusion: EX-PRESS filtration device has a good IOP-lowering effect and a low rate of complications in patients with advanced NVG associated with PDR. In addition, there was no loss of light perception or no line decrease of the BCVA.

Objective: We combined heads-up 3-dimensional (3D) 27-gauge microincision vitrectomy surgery (27GMIVS) with a very low-intensity illumination system. Methods: This study was based on a retrospective, interventional case series of 6 eyes of 6 patients with macular disease. All patients underwent heads-up 3D 27GMIVS and the power of the intraocular illuminator was set to its minimum level, 1% (approximately 0.1 lm), throughout the surgery. Results: We found that the procedure was easy when the heads-up 3D system was used, but not through the eyepiece of a microscope. All surgeries were successfully finished without any complications. Postoperative visual acuity was restored or maintained in all eyes during the follow-up period. Conclusion: Heads-up, 3D system-assisted 27GMIVS with minimal illumination enabled excellent intraoperative visualization of retinal tissues, caused minimal phototoxicity to the macular retinal cells, and might therefore represent the next step in the development of an ideal, minimally invasive method of treating macular disease.

Purpose.To determine the efficacy and safety of preoperative intravitreal conbercept (IVC) injection before vitrectomy for proliferative diabetic retinopathy (PDR).Methods.107 eyes of 88 patients that underwent pars plana vitrectomy (PPV) for active PDR were enrolled. All patients were assigned randomly to either preoperative IVC group or control group. Follow-up examinations were performed for three months after surgery. The primary bioactivity measures were severity of intraoperative bleeding, incidence of early and late recurrent VH, vitreous clear-up time, and best-corrected visual acuity (BCVA) levels. The secondary safety measures included intraocular pressure, endophthalmitis, rubeosis, tractional retinal detachment, and systemic adverse events.Results.The incidence and severity of intraoperative bleeding were significantly lower in IVC group than in the control group. The average vitreous clear-up time of early recurrent VH was significantly shorter in IVC group compared with that in control group. There was no significant difference in vitreous clear-up time of late recurrent VH between the two groups. Patients that received pretreatment of conbercept had much better BCVA at 3 days, 1 week, and 1 month after surgery than control group. Moreover, both patients with improved BCVA were greater in IVC group than in control group at each follow-up.Conclusions.Conbercept pretreatment could be an effective adjunct to vitrectomy in accelerating postoperative vitreous clear-up and acquiring stable visual acuity restoration for PDR.

Purpose. To evaluate efficacy of intravitreal triamcinolone (IVT) and bevacizumab (IVB) as adjunctive treatments to panretinal photocoagulation (PRP) in proliferative diabetic retinopathy (PDR). Methods. In 60 eyes of 45 patients with PDR, PRP (PRP group), PRP with IVT (IVT group), or PRP with IVB (IVB group) was performed. Regression of new vessels (NV), changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and contrast sensitivity at 1,2, and 6 months were evaluated. Results. Initial mean numbers of active NV and BCVA were 3.45 and 67.35 in the PRP group, 4.35 and 76.65 in the IVT group, and 4.79 and 75.53 in the IVB group. At the 6-month follow-up, numbers of active NV were 2.5 (P=0.064), 1.11 (P=0.000), and 1.11 (P=0.002), and there was a mean loss of 2,6 (P=0.055), 3.9 (P=0.011), and 0.9 letters (P=0.628) in the PRP, IVT, and IVB groups, respectively. Changes in CMT in the PRP and IVT groups were not significant, but significantly increased in the IVB group (P=0.032). Contrast sensitivity remained stable in PRP and IVB groups and slightly decreased in IVT group. Conclusions. Adjunctive use of both triamcinolone and bevacizumab with PRP lead to a greater reduction of active NV than PRP alone in PDR, although no differences were seen between the two of them.

Introduction: To report the 10 - year rate of vitrectomies and the associated factors in people with proliferative diabetic retinopathy (PDR) from a multicentric cohort of people with diabetes mellitus. Methods: Ten centres in India with established vitreoretinal services for over 10 years were invited to provide long-term data on PDR. People with Type 1 or 2 diabetes with a clinical diagnosis of active PDR in one or both eyes were included. Baseline data collected included age, sex, duration of diabetes, source of referral and best-corrected visual acuity and diabetic retinopathy status in both eyes. Available follow-up data included the numbers of panretinal photocoagulation (PRP) sessions, cataract surgery, treatment of diabetic macular edema, use of anti- vascular endothelial growth factor therapy, vitrectomy with or without retinal surgeries over 10 years. Results: Over 10 years, 89 % needed supplemental PRP after initial complete PRP. One – third required retinal surgery, 16 % needed intravitreal injection. Men (74.5%) had significant higher risk for vitreous surgery. Of the group with low risk PDR, 56.8% did not require vitreoretinal surgery, p <0.001. Of the patients who underwent cataract surgery and had intravitreal anti-VEGF injections, 78.5% and 28.2% needed subsequent vitreous surgery (VR), p=0.006 and <0.0001 respectively. Independent predictors of need for vitreo-retinal surgery included those who underwent cataract surgery and those with poor baseline visual acuity (logMAR). Eyes at lower risk for VR surgery included the eyes previously treated with PRP and low-risk PDR at baseline. Conclusion: Despite initial ‘complete’ PRP, one third of our study cohort needed vitrectomies over 10 years, highlighting that these patients require regular follow-up for a long period of time.

We describe a new technique for removing a large intraocular foreign body by 25-gauge microincision vitrectomy surgery (25G-MIVS). Noncomparative interventional case series were performed at a single centre. Two patients with a long smooth intraocular vitreal foreign body underwent phacoemulsification and aspiration, intraocular lens implantation, 25G-MIVS, and extraction of the foreign body. The foreign body was removed through a posterior capsulorhexis, anterior continuous curvilinear capsulorhexis, and a corneal incision. In both cases, the foreign body was safely removed through the corneal incision, and IOL was implanted and well positioned. The surgical incision did not require suturing. No postoperative complications associated with this technique were found. The corneal endothelial cell density was maintained over 2000 cells/mm2in both cases during recent follow-up examinations. Our findings indicate that 25G-MIVS with this technique can be used to extract a long slender smooth foreign body. It is safe, without complications, and can be performed without enlarging the 25-gauge sclerotomy.

Vitrectomy surgery in proliferative diabetic retinopathy improves the vision-related quality of life. However, there is lack of data on the duration of maintenance of visual gains post vitrectomy. This study thus aimed to determine the survival time of visual gains and the prognostic factors of vision loss after vitrectomy surgery for complications of proliferative diabetic retinopathy. A retrospective cohort study was conducted in an ophthalmology clinic in Malaysia. We included 134 patients with type 2 diabetes mellitus on follow-up after vitrectomy for proliferative diabetic retinopathy. Visual acuity was measured using the log of minimum angle of resolution (LogMar). A gain of ≥0.3 LogMar sustained on two subsequent visits was considered evidence of visual improvement post vitrectomy. Subjects were considered to have vision loss when their post-operative visual acuity subsequently dropped by ≥0.3 LogMar. Kaplan–Meier analysis was used to determine the survival time of visual gains. Cox Proportional Hazard regression was used to determine the prognostic factors of vision loss. The median age of patients was 56.00 years (IQR ± 10.00). The median duration of diabetes mellitus was 14.00 years (IQR ± 10.00). Approximately 50% of patients with initial improvement post vitrectomy subsequently experienced vision loss. The survival time, i.e., the median time from surgery until the number of patients with vision loss formed half of the original cohort, was 14.63 months (95% CI: 9.95, 19.32). Ischemic heart disease was a significant prognostic factor of vision loss. Patients with underlying ischemic heart disease (adjusted HR: 1.97, 95% CI: 1.18, 3.33) had a higher risk of vision loss post vitrectomy, after adjusting for other factors. Approximately half the patients with initial visual gains post vitrectomy maintained their vision for at least one year. Ischemic heart disease was a poor prognostic factor for preservation of visual gains post vitrectomy.

Abstract Background To evaluate the efficacy and outcomes following one-way surgical technique for the treatment of vitreous hemorrhage post vitrectomy in proliferative diabetic retinopathy (PDR) patients. Methods Those PDR patients who had vitrectomy with balance saline tamponade and then developed vitreous hemorrhage post vitrectomy were included in this study. 47 patients underwent the one-way air-fluid exchange surgical procedure with a 10 ml syringe used to exchange between 4.5–5.5 ml of fluid in the treatment room. After the air-fluid surgical exchange procedure, additional treatments were administered when needed. Best corrected visual acuity (BCVA) and occurrence of intra-procedural and post-procedural complications were collected and analyzed. Results A total of 47 eyes of 47 PDR patients with a mean age of 50.8 ± 12.0 years were reviewed. All 47 eyes had undergone vitrectomy with balance saline tamponade because of PDR. 4 of them were diagnosed with type 1 diabetes mellitus (T1DM), and 43 of them were diagnosed with type 2 diabetes mellitus (T2DM). All the 47 eyes were given the one-way air-fluid exchange procedure in the treatment room. In 4 cases the procedure was administered twice, and in 1 case the procedure was administered three times, followed by additional retinal photocoagulation and one intravitreal injection of Conbercept. The BCVA at the final follow-up was significantly improved from the initial acuity baseline in all cases. No complications were observed during the follow-ups. Conclusion This one-way air-fluid exchange procedure could effectively exchange the vitreous hemorrhage and improve visual acuity without obvious complications in treating vitreous hemorrhage post vitrectomy.

Proliferative diabetic retinopathy (PDR) is the most severe case of diabetic retinopathy that can cause visual impairment. This study aimed to reveal the factors correlated with better postoperative visual acuity after a long follow-up in patients who underwent vitrectomy for PDR. We retrospectively analyzed the data set including systemic findings, ocular findings, and surgical factors from registered patients who could be completely followed up for 2 or 4 years after vitrectomy. We ultimately enrolled 128 eyes from 100 patients who underwent vitrectomy for PDR between January 2008 and September 2012 and were followed up for >2 years. Among them, 91 eyes from 70 patients could be followed up for 4 years. Factors related to the postoperative visual acuity of ≥20/40 and ≥20/30 after 2 and 4 years were investigated by logistic regression analysis. Better postoperative visual acuity correlated with the following factors: no rubeosis iridis ([≥20/40 at 2 years; odds ratio {OR}, 0.068; 95% confidence interval {CI}, 0.012–0.39; P = 0.003], [≥20/30 at 2 years; OR, 0.07; 95% CI, 0.01–0.40; P = 0.03], [≥20/30 at 4 years; OR, 0.078; 95% CI, 0.006–0.96; P = 0.04]), no fibrovascular membrane [(≥20/40 at 2 years; OR, 0.22; 95% CI, 0.061–0.81; P = 0.02), (≥20/40 at 4 years; OR, 0.26; 95% CI, 0.07–0.94; P = 0.04), (≥20/30 at 4 years; OR, 0.14; 95% CI, 0.04–0.52; P = 0.004)], existing vitreous hemorrhage (≥20/30 at 2 years; OR, 9.55; 95% CI, 1.03–95.27; P = 0.04), and no reoperation ([≥20/40 at 4 years; OR, 0.15; 95% CI, 0.03–0.78; P = 0.02], [≥20/30 at 4 years; OR, 0.06; 95% CI, 0.07–0.54; P = 0.01]). Treatment provision before disease severity and treatment without complications were associated with good postoperative visual acuity.

Purpose: Pediatric macular holes occur often related to trauma and rarely require surgical intervention. The purpose of the present study was to evaluate outcomes of microincisional vitrectomy surgery. Methods: A multicenter retrospective consecutive case series was conducted of pediatric patients undergoing surgery for macular hole repair. Results: A total of 31 eyes from 8 centers were included in this study. The mechanism of macular hole development was blunt trauma in 30 eyes (97%) and industrial laser in 1 eye (3%). The rate of anatomic closure after primary vitrectomy was 81% (25 eyes); the final anatomic closure rate after a secondary vitrectomy was 94% (29 eyes). There was a statistically significant improvement in visual acuity from initial presentation (20/164) to final follow-up (20/100) ( P = .009). Conclusions: Microincisional vitrectomy surgery for pediatric macular holes results in substantial anatomic success and modest improvement in visual acuity.
