Background/Aim: To evaluate the efficacy of trabeculectomy with mitomycin C (MMC) for lowering intraocular pressure (IOP) in patients with open angle glaucoma (OAG) secondary to emulsified silicone oil (SO) after pars plana vitrectomy. Methods: A single-center, prospective study was conducted, from December 2014 to December 2019, on 56 consecutive patients with an uncontrolled elevation of IOP after SO removal. The primary end-point was the IOP at the three-years follow-up visit. Complete surgical success was defined as an IOP ranging from 7 mmHg to 18 mmHg without glaucoma medication. Qualified success was defined as IOP ? 21 mmHg with one or two topical medications. Results: Fifty-six patients with mean (standard deviation) age of 56.6 (13.1) years had a mean baseline IOP of 42.3 (39.3 to 45.3) mmHg, which reduced to 18.6 (17.9 to 19.3) mmHg at 3 years after surgery (P < 0.0001). 17 (30.4%) eyes were classified as complete success, 21 (37,5%) as qualified success, and 18 (32.1%) as failure. In all treated patients, the number of antiglaucoma medications was significantly reduced from 2.85 (0.77) to 1.63 (0.62), p<0.0001. Conclusion: Trabeculectomy with MMC may be an option for lowering IOP in patients with OAG secondary to emulsified SO which was not controlled with maximum antiglaucomatous medical treatment.

The Right

A 36-year-old patient presented to the hospital with recurrent dislocation of the intraocular lens (IOL). The patient with the diagnosis of familial ectopia lentis was first operated on for crystalline lens subluxation in the left eye in 2007 and in the right eye in 2009. In both eyes, lens extraction with anterior vitrectomy and transscleral fixation of a rigid IOL was performed. In 2011, the IOL in the right eye luxated into the vitreous cavity due to ocular trauma. The patient underwent a pars plana vitrectomy with the IOL resuturation to the sclera. Seven years later, a spontaneous vision loss in the right eye was caused by a retinal detachment. The pars plana vitrectomy with silicone oil tamponade and a consequential oil removal three months later were performed in 2018. The follow-up examination revealed recurrent IOL dislocation in the same eye. Due to a history of previous suture-related complications a decision was made to remove the subluxated rigid polymethyl-methacrylate (PMMA) IOL and fixate to sclera a sutureless SOLEKO FIL SSF Carlevale lens. The purpose of this report is to present a single case of a 36-year-old patient who was presented to the hospital with recurrent dislocation of the intraocular lens. In a three-month follow-up period, a good anatomical and functional outcome was finally obtained with transscleral sutureless intraocular lens. This lens is an option worth considering especially in a young patient with a long life expectancy and physically active.

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.

Background. To investigate the efficacy of selective laser trabeculoplasty (SLT) for lowering intraocular pressure (IOP) in patients with open angle glaucoma (OAG) secondary to emulsified silicone oil (SO).Methodology/Principal Findings. Prospective, interventional, consecutive case series of 11 eyes with sustained elevation of IOP after SO removal. The mean IOP at baseline, week 1, month 1, month 3, and month 6 was evaluated. The mean baseline IOP was significantly decreased from 25 ± 2.7 mmHg to 18.4 ± 5.5 mmHg at week 1(P=0.01), 17.9 ± 3.1 mmHg at month 1(P=0.008), 15.8 ± 3.9 mmHg at month 3(P=0.003), and 16.2 ± 4.7 mmHg at month 6(P=0.004). IOP < 21 mmHg was achieved in 91% of the eyes without a significant complication at month 6.Conclusion/Significance. SLT may be successful for lowering IOP in patients with OAG secondary to emulsified SO which was not controlled with maximum antiglaucomatous medical treatment.

PurposeTo review a series of highly myopic eyes with retinal detachment undergoing pars plana vitrectomy with autologous internal limiting membrane (ILM) flap placed over posterior retinal breaks located in areas of choroidal atrophy.MethodsRetrospective review of 13 consecutive patients receiving pars plana vitrectomy with ILM flap over causative breaks, compared with 19 controls receiving the same surgery with ILM peeling but no ILM flap. Main outcome measures included anatomical success rate, visual acuity, number of surgeries and the rate of silicone oil removal.ResultsPatients in the ILM group required 2.08±0.37 interventions versus 2.58±0.75 in the control group (p=0.037). One (1/13; 7.6%) patient in the ILM group required additional unplanned surgery versus 8/19 (42.10%) in the control group (p=0.038). Final anatomical success rate defined as attached retina after silicone oil (SiO) removal was 13/13 in the I-ILM group and 14/19 (73.6%) in the control group (p=0.052). No patients (0/13) in the I-ILM group retained SiO at the end of follow-up versus 4/19 (21.1%) patients in the control group (p=0.061). Best-corrected visual acuity at the end of follow-up was logMAR 0.65±0.36 (20/91 Snellen) in the ILM group and logMAR 0.89±0.44 (20/158 Snellen) in the control group (p=0.20).ConclusionAutologous ILM may help seal posterior retinal breaks and improve the surgical prognosis of retinal detachment due to breaks located over areas of choroidal atrophy within the myopic staphyloma.

Pars plana vitrectomy (PPV) with silicone oil implantation (SOI) was performed for advanced proliferative diabetic retinopathy (PDR) in 110 eyes of 98 diabetic patients. In, 77 eyes (70%) it was a primary SOI as part of the initial operation; in 33 eyes (30%) it was a secondary SOI in reoperations. Indications for SOI were traction retinal detachment of the posterior pole, combined traction and rhegmatogenous detachment, vitreous haemorrhage with florid vascularised fibrous proliferations, and recurrent vitreous haemorrhage after PPV. The patients were followed up for 24 to 72 months, with a mean of 53 months. At the end of follow-up, anatomical success was achieved in 63 eyes (57%), and functional success with visual acuity 0.01 and better in 35 eyes (32%). Functional failures were caused by retinal redetachment in 47 eyes (43%), by secondary glaucoma in 10 eyes (9%), retinal ischemia in 15 eyes (13%) and keratopathy in three eyes (3%). The functional success rate decreased with follow-up from 67% after six months to 50% by 60 months after SOI. Silicone oil bubble in the anterior chamber, rubeosis iridis, cataract, and glaucoma were the most frequent postoperative complications. PPV with SOI was highly effective in many serious complications of advanced PDR. Functional success was mostly lasting and markedly improved the quality of life of these patients.

Boston Type 1 Keratoprosthesis

Purpose. To identify the incidence of endophthalmitis and visual outcomes in eyes with Boston type 1 keratoprosthesis combined with pars plana vitrectomy and silicone oil insertion (KPro + PPV + SOI) as compared to eyes receiving Boston type 1 keratoprosthesis (KPro) alone. Patients and Methods. Retrospective chart review of 29 eyes of 27 patients with KPro having at least 12-month follow-up. Thirteen of these eyes had hypotony and/or retinal detachment in addition to corneal pathology and thus received KPro + PPV + SOI. Polymyxin-trimethoprim with a quinolone was used as chronic topical antibiotic prophylaxis in both groups after the first postoperative month. Outcome measures recorded at the 1-, 3-, 6-, 12-, and 24-month follow-up visits included best-corrected visual acuity (BCVA) and rates of postoperative complications. Results. All the patients had completed 24-month follow-up except one case in the KPro group who lost to follow-up after 12-month visit. In the KPro + PPV + SOI group, no eyes had developed endophthalmitis by the 24-month follow-up visit versus 5 eyes of 5 patients in the uncombined KPro group (P=0.048). The 2-year cumulative endophthalmitis incidence was 31.2% in the KPro group versus zero in the KPro + PPV + SOI group (P=0.030). Four of these 5 eyes had vitreous taps with positive cultures; 2 were positive with Staphylococcus aureus, 1 with coagulase-negative staphylococci, and 1 with Streptococcus pneumoniae. Other complications included KPro extrusion (1 in each group), retinal detachment (2 in the KPro and 1 in the KPro + PPV + SOI group), newly developed glaucoma (2 in each group), and retroprosthetic membrane (9 in the KPro and 5 in the KPro + PPV + SOI group). The KPro group had better average preoperative BCVA compared to those of the KPro + PPV + SOI group (−2.29 ± 0.72 LogMAR, versus −2.95 ± 0.30 LogMAR; P=0.004). No statistically significant difference in BCVA was noted in subsequent follow-up visits. Conclusion. The addition of PPV and SOI to the KPro implantation in the eyes with corneal pathology, as well as hypotony and/or retinal detachment, is a safe and effective procedure for visual rehabilitation. Pars plana vitrectomy and silicone oil insertion may have a protective effect against the development of postoperative endophthalmitis in eyes receiving KPro.

Purpose. To evaluate the effectiveness and safety of perfluorohexyloctane (F6H8) for intraoperative flattening of the retina and of F6H8/silicone oil (SO) 1000 cSt as a postoperative tamponade for inferior retinal detachment with inferior proliferative vitreoretinopathy.Methods. This is a retrospective review of 22 patients who underwent pars plana vitrectomy using F6H8 as an intraoperative tool to flatten the retina. At the end of the surgery a direct partial exchange between F6H8 and SO 1000 cSt was performed, tamponing the eye with different ratios of F6H8/SO (70/30, 60/40, 50/50, 40/30, and 30/70). Anatomical and functional results and complications were evaluated over the follow-up period (mean 22.63 months).Results. F6H8 was efficacious for intraoperative flattening of the retina. Twenty-one of the 22 patients achieved a complete retinal reattachment. Postoperative visual acuity (VA) ranged from light perception to 20/70, with 72% of patients obtaining VA better than 20/400. No emulsification/inflammation was observed whatever the ratio of F6H8/SO used. With higher ratios of F6H8/SO (70/30 and 60/40) cloudiness of the tamponade was observed. A transparent mixture was present with all the other ratios.Conclusions. The surgical technique adopted is very simple and safe. The optimal F6H8/SO ratio seems to be between 50/50 and 30/70.

Purpose: Choroidal coloboma (CC) eyes are associated with a high risk of retinal detachment (RD), which are challenging to repair. Methods: We retrospectively evaluated medical records of 30 patients with CC associated with RD who underwent pars plana vitrectomy at our tertiary care center. Data recorded were age, CC and RD morphology, breaks, resurgeries performed, and final outcome. Results: Patients’ ages ranged from 2 to 49 years. CC was present in 53 of 60 eyes (88%), with 41 of 60 eyes (68.3%) associated with iris coloboma. RD was present in 36 of 53 CC eyes (67.9%), with 10 of 53 (18.9%) having bilateral RD. Thirty-one eyes with RD underwent 23-gauge pars plana vitrectomy. Colobomatous region breaks were detected in 5 of 31 eyes (16.1%), peripheral breaks only in 12 of 31 (38.7%), and both types in 3 of 31 eyes (9.7%). Silicone oil endotamponade was used in 29 of 31 eyes (93.5%) and perfluoropropane (C3F8) in 2 of 31 eyes (6.45%). Median postoperative follow-up duration was 31.5 months. Fourteen of 31 eyes (45.2%) developed redetachment requiring resurgery, with 50% developing within 6 months. Eighteen of 31 eyes (58.1%) maintained retinal attachment at last follow-up without endotamponade, whereas the rest were oil filled. Final visual outcome between macula-involved and macula-spared CC eyes was not significantly different; however, best visual acuity achieved any time during follow-up was significantly better in macula-spared eyes. Conclusions: RD surgery in CC eyes has a risk of frequent redetachments and subnormal gain of vision over the long term, especially in colobomas involving the macula. Endolaser in 360° peripheries in addition to barrage of the margin of the coloboma may be considered to help maintain the attached retina.

Purpose: The purpose of this study was to compare rates of clinically significant complications between 23- and 25-gauge pars plana vitrectomy (PPV) in vitreoretinal surgery. Methods: Demographics, PPV indication, and surgical complications were reviewed. Patients with prior PPV or other retina surgery; cases requiring silicone oil removal, keratoplasty, or glaucoma valve implant; patients <18 years old; or patients with <4 months of follow-up were excluded. Comparative and descriptive statistics were used to evaluate the data. Results: A total of 579 eyes met inclusion criteria, and their charts were reviewed. Demographics, PPV indication, follow-up time, and lens status were similar ( P > .05). A 23-gauge PPV was performed more frequently than a 25-gauge PPV (328 vs 251 eyes, respectively). Although rates of eyes with a clinically significant postoperative complication requiring surgical intervention were higher in 23-gauge PPV (112/325, 34.4%) than in 25-gauge PPV (54/250, 21.6%), PPVs indicated by rhegmatogenous retinal detachment were more common with 23-gauge PPVs (155/325, 47.7%) than with 25-gauge PPVs (37/250, 14.8%; P <.001) and were more likely to have postoperative complications; however, rates of recurrent retinal detachments were not different in the 2 cohorts ( P = .862). When controlling for differences in indication, there was a moderately higher rate of postoperative complications following 23-gauge PPV ( P = .063). Conclusions: This retrospective review suggests that clinically significant complications are moderately more likely following 23-gauge PPV compared with 25-gauge PPV, even when the differences in surgical indication are considered.
