Purpose: To evaluate the surgical outcome of deep or full-thickness suture penetration during combined pars plana vitrectomy and scleral buckle (PPV/SB) surgery. Methods: Clinical data of patients who underwent PPV/SB for retinal detachment in our practice between June 2017 and April 2019 were reviewed. Cases with full-thickness scleral penetration were identified. Data including initial presentation, intraoperative complications, and management were collected. Long-term surgical outcome, complications, and recurrent detachment were determined. Results: Twenty-three cases with evidence of suture penetration were identified. In none of the cases the penetrated suture was visible in the subretinal space. The suture was replaced in cases with persistent leakage through the penetration site or when the surgical plan involved silicone oil insertion. Subretinal hemorrhage was noted during vitrectomy in 7 (30%) patients. The subretinal hemorrhage migrated to the macula in 2 (9%) cases and was drained through a posterior retinotomy. Retinal incarceration was noted in 4 (17%) cases and was released using a focal retinotomy in 2 (9%)cases to reattach the retina. Late complications included epiretinal membrane in 6 (26%) and recurrent detachment occurred in 2 (9%) patients. Final anatomical success was achieved in all patients. Conclusions: We propose new principles in the management of suture penetration during combined PPV/SB surgery. In the absence of a visible penetrated suture, suture replacement is required when there is profuse leakage through the penetration site or if silicone oil is used as tamponade. We recommend removal of submacular hemorrhage through a posterior retinotomy. The incarcerated retina can be flattened using release retinotomies.

Abstract Background To investigate the long-term outcomes and complications of scleral-fixated intraocular lens (SFIOL) implantation without conjunctival peritomies and sclerotomy in patients with a history of ocular trauma with inadequate capsular support during primary pars plana vitrectomy or silicone oil removal. Methods Records of ocular trauma patients who underwent implantation of SFIOL without conjunctival peritomies and sclerotomy during primary pars plana vitrectomy or silicone oil removal. Results Sixty-nine eyes of 69 patients were included in this study. The median follow-up period was 34 months (range, 6-99 months). The average patient age at the time of surgery was 44 years old (range, 4-80 years). At the end of follow-up, the preoperative mean of best corrected visual acuity (BCVA) was 0.79 ± 0.86 log of the minimum angle of resolution (logMAR), which improved 0.20 ± 0.26 logMAR postoperatively (P = 0.01). BCVA improved or remained unchanged in 64 eyes (92.8%), VA decreased two lines in five eyes (7.2%). Early postoperative complications included transient corneal edema in seven eyes (10.1%), minor vitreous hemorrhage in four eyes (5.8%), transient elevated intraocular pressure (IOP) in one eye (1.4%), and hypotony in three eyes (4.3%). Late postoperative complications included persistent elevated IOP in five eyes (7.2%), epiretinal membrane formation in three eyes (4.3%), and cystoid macular edema noted in one eye (1.4%). Conclusion Use of a scleral-fixated intraocular lens implantation without conjunctival peritomies and sclerotomy in ocular trauma patients during either primary pars plana vitrectomy or second silicone oil removal is a valuable approach for the management of traumatic aphakia in the absence of capsular support.

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.

Introduction: Perfluorocarbon (PFCL) is an essential adjunct of retinal detachment surgery. Subfoveal migration of PFCL is a rare and vision threatening complication of its use. Various techniques have been described for its removal. However, no consensual technique of its removal has been established. We present a nova, relatively atraumatic and cost effective way of PFCL removal using a widely available 26G spinal anesthesia needle. Case: An 18 years old myopic patient who had undergone left eye pars plana vitrectomy (PPV) for myopic Rhegmatogenous Retinal Detatchment (RRD) in the past presented after 1 month with retained subfoveal PFCL. Its subretinal location was confirmed by Optical Coherence Tomography (OCT). He was taken up for early Silicone Oil Removal (SOR) along with removal of retained subfoveal PFCL under high magnification by using a surgical disposable contact macula lens. A 26G spinal anesthesia needle tip was used to dissect a small separation parallel to the nerve fibers at the temporal edge of tense cystic PFCL bleb. Silicone tipped flute cannula was used to passively aspirate the sub retinal PFCL under fluid with no additional intervention. No barrage LASER was done. Observation: Anatomical restoration of the retina was noted both intraoperatively and post-operatively. SD-OCT showed complete restoration of anatomical layers with no presence of intraretinal cystic cleft both at day 1 and 30 days postoperatively. Conclusion: Safe removal of subfoveal PFCL can be done with 26G spinal anesthesia needle which is atraumatic, inexpensive and readily available. However, long term validity of this process needs to be established in a case series.

Aims. To compare the surgical outcome of pars plana vitrectomy (PPV) for full-thickness macular hole (FTMH) with and without lamellar hole-associated epiretinal proliferation (LHEP). Methods. This retrospective study included 158 eyes of 158 patients with FTMH treated with PPV. The following variables were analyzed: sex, age, preoperative best corrected visual acuity (pre-BCVA), BCVA 6 months after the surgery (6M-BCVA), the axial length of eye, the minimum diameter of FTMH, the diameter of basal side of FTMH, postoperative continuity of subfoveal ellipsoid zone (EZ) and external limiting membrane (ELM), and the preoperative presence of LHEP. Results. Twenty-eight eyes had FTMH with LHEP and 130 without LHEP. The mean ± SD age (years) was 72.6 ± 7.9 and 68.6 ± 8.7, respectively (p=0.02). 6M-BCVA was 0.38 ± 0.30 and 0.26 ± 0.25, respectively (p=0.03). The diameter of basal side of FTMH (μm) was 901.5 ± 404.9 and 658.9 ± 288.1, respectively (p=0.00027). EZ was disrupted in 24 eyes and 63 eyes, respectively (p=0.00071). ELM was disrupted in 15 eyes and 23 eyes, respectively (p=0.00015). The FTMH diameters and the presence of LHEP were inversely correlated with the continuity of EZ and ELM. Conclusion. The preoperative appearance of LHEP could be one of the prognostic factor for the treatment of FTMH.

Purpose To compare the intraoperative complications between 23-G and 20-G instrumentation in patients undergoing pars plana vitrectomy (PPV). Methods This was a retrospective comparative study of 4,274 PPV procedures by the same surgical team between 1998 and 2016. A total of 2,648 operations were carried out with 20-G surgery and 1,626 operations with 23-G surgery. Main outcome measures were the incidence of choroidal haemorrhage, iatrogenic retinal break, and lens touch. Results The most frequent surgical indication in both 20-G and 23-G was rhegmatogenous retinal detachment (RRD), 38.7% (1,026/2,648) and 45.9% (746/1,626), respectively. The frequency of choroidal haemorrhage was 1.0% with 20-G surgery (26/2,648) vs 0.6% with 23-G (9/1,626, p = 0.16). Subgroup analysis showed the increased risk was present in RRD surgery, 1.6% (16/1,026) vs 0.1% (1/746, p = 0.002), but not in all other indications combined, 20-G with 0.6% (10/1,622) and 23-G 0.9% (8/88, p = 0.46). This increased risk was also true for RRD when excluding combined scleral buckle surgery. There was an increased risk of iatrogenic retinal break in RRD cases undergoing 20-G, 5.8% (60/1,026), compared to 23-G vitrectomy, 1.9% (14/746, p<0.0001). There was no difference in rates of lens touch between 20-G and 23-G. Conclusions 23-G microincisional PPV has a lower risk of choroidal haemorrhage and iatrogenic retinal tears than 20-G vitrectomy particularly for eyes with RRD.

Introduction. Choroidal coloboma is a congenital defect caused by an inadequate closure of embryonic fissure. About 40% of the eyes with the choroidal coloboma (CHC) develop the retinal detachment (RD). It is extremely difficult to manage these cases due to the lack of pigmentation at the site of choroidal coloboma. Outline of Cases. This is a case series of five patients with CHC and RD who were successfully operated using one of two different surgical techniques: pars plana vitrectomy (PPV) + silicone oil internal tamponade and/or scleral buckle with encircling band with laser photocoagulation (SB+EB+LPC) around the coloboma. The purpose of this paper is to present how to successfully handle patients with CHC, who have concurrent retinal detachment in the same eye and to compare two different techniques and indications for the predominant use of one of them in a specific case. Conclusion. Both surgical techniques can be applied with equal success in the operation of retinal detachment in eyes with the chorioidal coloboma. Which one will be used depends only of the posterior segment of eye findings. We use scleral buckling in cases with RD accompanied by CHC when the peripheral break is evident and there are no breaks in the coloboma itself. We also perform, 2-3 days after surgery, laser burns around the coloboma, which is our modification of this technique. In all other cases it is indicated to perform PPV+silicon oil internal tamponade.

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.

Abstract Background Treatment of recurrent retinal detachment (re-RD) following vitrectomy (post-gas/air tamponade and post-silicone oil removal) is challenging. Previously reported treatment is commonly revision pars plana vitrectomy (PPV) combined with tamponade, which is invasive and a burden both economically and emotionally when compared with scleral buckling (SB). The purpose of this study is to report anatomical and functional outcomes of SB with or without gas tamponade in eyes with recurrent retinal detachment (re-RD) that previously underwent PPV at least once. Methods We retrospectively reviewed the medical records of 14 patients (14 eyes) who underwent PPV at least once and were treated with SB after re-RD. Preoperative characteristics, intraoperative complications, and postoperative data were assessed. The final anatomical and functional outcomes were analyzed. Results The original PPV was performed for primary rhegmatogenous retinal detachment in 11 eyes, macular hole retinal detachment in 2 eyes, and myopic foveoschisis in 1 eye. Previously, 3 eyes underwent one PPV with gas tamponade, and the remaining 11 (79%) eyes underwent 2–5 operations. Seven eyes underwent the procedure with gas injection. At the last follow-up, 13 eyes achieved total retinal attachment and 1 eye had re-RD. The postoperative intraocular pressure was within the normal range, except in 1 eye (6 mmHg). The finest postoperative best-corrected visual acuity (BCVA) was 20/25. There was a significant improvement in BCVA from 20/160 ± 20/63 at baseline to 20/80 ± 20/50 at the last visit in the 13 successfully treated eyes (P = 0.025). Conclusions SB can be effective for re-RD after PPV in specific cases.
