Purpose: To evaluate common indications and anatomical outcomes of PPV for posterior segment ocular diseases in patients presenting at private retina clinic in Lahore Study design: Cross sectional survey Methods and materials: Over the period of three years, from 1st April 2017 to 3oth April 2020, all patients fulfilling inclusion criterion, were included in study after approval from hospital ethical committee. After taking history and detailed ocular examination, diagnosis was confirmed by B scan or OCT, Hepatitis B & C screening done. The patient age, gender, laterality of eye, lens status, macular status, type of retinal pathology, type of anesthesia, procedure done and type of vitreous tamponade if used were noted. All procedures were performed by a single surgical team and patients were followed for six months for anatomical success or any complication. Data was analyzed by SPSS 25. Results: Out of 266 total patients, 168 (63.2%) were males and 98 (36.8%) were females. Right eye was involved in 125 (47%) and left in 141 (53%). Age range was from 2 years to 83years, mean age for males was 47.30, for females 48.07 years, median age was 50 years, mean age for GA was 30.62 years and 51.71 for LA patients. The highest incidences of posterior segment ocular problems were observed in patients with age range 51 to 60 years. The commonest indication for posterior segment surgery were RRD seen in 107 (40.23%), ROSO in 51 (19.17%) and vitreous hemorrhage 33 (12.41%). Endophthalmitis was indication in 20 (7.52%), dropped nucleus in 11 (4.13%), Macular hole in 7 (2.63%) and ERM in 3 (1.13%). Asteroid hyalosis, intraocular IOFB and diagnostic vitrectomy were least common indication, each seen in 1 (0.5%) patient. Silicon oil was most commonly used Endo tamponade used in 138 (51.88%) patients. All patients were followed for 6 months with vision and retinal status. All patients who underwent pars plana vitrectomy surgery were stable with anatomical success rate till 6 months postoperatively except 10 (3.76%) who required re do operation for retinal detachment or some other complications. Conclusion: Current practice in ophthalmology shows increased frequencies of internal approach (PPV) for vitreoretinal diseases rather external approach (SB). Silicon oil was most common internal tamponade used. Diabetic retinopathy was important cause of vitreous hemorrhage and TRD. Patients should be educated regarding regular fundoscopy and good systemic control of diabetes. Higher incidence of retinal detachment among all age groups needs awareness and education about its warning ocular symptoms. Key words: PPV (Pars plana vitrectomy), RRD (Rhegmatogenous retinal detachment), SB (Scleral buckling), TRD (Tractional retinal detachment), ROSO (removal of silicon oil), GA (general anesthesia), LA (local anesthesia)

Objective:  To report our experience with 27 gauge (27G) pars plana vitrectomy (PPV) system for a variety of simple to complex posterior segment disorders Methods: Single center, Retrospective, Cohort study. Data of 665 eyes of 574 patients that underwent 27G PPV for a variety of indications from July 2015 to June 2019 at a tertiary care hospital was analyzed. Results: Common surgical indications included; Diabetic tractional retinal detachment (196, 29.5%), vitreous haemorrhage (191, 28.7%), full thickness macular hole (80, 12%), epiretinal membrane (66, 9.9%), endophthalmitis (26, 3.9%), tractional diabetic macular edema (14, 2.1%), ectopia lentis (11, 1.7%), dropped lens matter (13, 2%) and others (68, 10.2%). Mean operating time was 62 ± 37 minutes. With the exception of 2 cases where 20G fragmatome was utilized, no case required conversion to 20 gauge system while a 25G trocar was used for the silicon oil injection. Per-operative complications included; iatrogenic retinal tear (2 eyes, 0.3%) and supra choroidal silicon oil migration (1 eye, 0.15%). Post-operative complications were raised IOP (7 eyes, 1%), endophthalmitis (1 eye, 0.15%), hemorrhagic occlusive retinal vasculitis (1 eye, 0.15%) and retinal detachment (2 eyes, 0.3%). Mean Visual Acuity improved from 1.62 ± 0.68 logarithm of minimum angle of resolution (logMAR) to 0.4 ± 0.38 logMAR (P <0.001). Conclusion: With 3 months follow up time, 27 G PPV has proved to be a safe and effective system for both simpler and complex retinal pathologies requiring significant surgical manipulation.

Purpose To assess the occurrence of peripheral vitreoschisis-induced vitreous cortex remnants (p-VCRs) in primary rhegmatogenous retinal detachment (RD) and investigate whether the presence of p-VCRs results in a greater risk of RD recurrence, secondary to Proliferative Vitreoretinopathy (PVR) development after pars plana vitrectomy (PPV). Methods Patients who underwent PPV for primary rhegmatogenous RD between January 2016 and December 2018 were included. The presence of residual p-VCRs was confirmed intraoperatively using triamcinolone acetonide (TA). Patients with p-VCRs were divided into two groups: Group A comprised of patients who underwent PPV without p-VCR removal, while Group B included patients who underwent PPV with p-VCR removal. Results Four hundred-thirteen eyes with evidence of p-VCR were analyzed. Two-hundred-twenty-three eyes underwent PPV without VCR removal (Group A), while 190 eyes underwent PPV with p-VCR removal (Group B). Primary anatomical success was 91.5% in the Group A and 95.4% in the group B. Retinal re-detachment due to PVR occurred in 17 (7.6%) eyes in Group A and in four (2.1%) eyes in Group B within the first 3 months (p  =  0.01). Among group A, in 11 eyes, there was a diffuse posterior PVR grade C, while six eyes were focal PVR grade C. In Group B, we observed four retinal re-detachment due to focal PVR grade C. Conclusion The presence of p-VCRs seems to be associated with a higher incidence of PVR development and might also result in more complex RD recurrence, this suggests the need for more aggressive VCRs removal during the first surgery.

The Early Treatment Diabetic Retinopathy Study (ETDRS) was a randomized clinical trial involving nearly four thousand diabetic patients with early proliferative retinopathy, moderate to severe nonproliferative retinopathy, and/or diabetic macular edema in each eye. This paper (ETDRS report number 17) describes the baseline previtrectomy characteristics, initial treatment assignments, indications for vitrectomy, and visual outcomes in the subgroup of patients in the ETDRS who had pars plana vitrectomy (PPV). The study showed that pars plana vitrectomy could improve visual outcomes in patients with complications from proliferative diabetic retinopathy such as vitreous hemorrhage and retinal detachment. PPV continues to play an important role in the management of complications from proliferative diabetic retinopathy.

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.

Background. With the advances in surgical tools, simultaneous removal of cataract associated with vitreoretinal disorders is gaining popularity. This combined surgery offers several advantages besides limitations. The aim of this study is to assess the outcome and complications of phacoemulsification combined with pars plana vitrectomy (PPV). Patients and Methods. In this retrospective review, medical charts of patients undergoing phacovitrectomy for coexisting cataract and various vitreoretinal disorders were analyzed. Patient demographics, retinal diagnosis, visual acuities (VA) in logMAR, intraocular pressure (IOP), intraoperative and postoperative complications were assessed. Clear corneal phacoemulsification and 23-gauge transconjunctival PPV were administered in all cases. Results. Eighty-four eyes of 64 (76.2%) males and 20 (23.8%) females were enrolled. The average age of patients was 59.5 ± 13.8 (18–81). The average period of follow-up was 7.2 ± 7.5 months (1–36). The vitreoretinal diagnoses were as follows: 28 (33.3%) rhegmatogenous retinal detachment, 23 (27.4%) vitreous hemorrhage, 12 (14.3%) intraocular foreign body, 12 (14.3%) epiretinal membrane, 4 (4.8%) macular hole, 4 (4.8%) tractional retinal detachment, and 1 (1.2%) vitreomacular traction. The most common intraoperative complications were miosis and rupture of the posterior capsule (92.9% and 8.3%, respectively). In 8 (9.5%) cases, there was fibrin in the anterior chamber. Posterior synechia developed in 7 (8.3%) of cases. No severe increase in intraocular pressure was evident. Conclusion. Phacoemulsification combined with PPV is a safe and efficient way of management in cases where cataract coexists with vitreoretinal pathologies.

Introduction: Vitreous hemorrhage is the presence of blood in the vitreous cavity. This condition could impair the visual function and hindered the clinician’s ability to examine the posterior segment of the eye.  Pars plana vitrectomy (PPV) not only act as a surgical treatment of choice but also diagnostic procedure. Immediate PPV has the advantage to optimalize visual acuity Methods: Retrospective descriptive study of vitreous hemorrhage patients underwent pars plana vitrectomy in Ciptomangunkusumo Hospital, Indonesia from January to December 2018 Result: There were 160 cases of vitreous hemorrhage cases undergoes pars plana vitrectomy in 2018. Most frequent etiology was proliferative diabetic retinopathy (49.4%). Rebleeding was found only in 8 cases within the period of three months follow up. Final visual acuity was improved in majority of the cases and found to be related to timing of the surgery. Conclusion: Early vitrectomy along with systemic control of underlying factors lead to improvement of visual acuity in vitreous hemorrhage.

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.

Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability of well trained vitreo retina surgeons are the basic need to accomplish this work.  Encircling band provide permanent 360° support to close the anterior retinal break and prevent traction on the retina. The objective of this study is to analyse the clinical characteristics and predictors of the final visual outcome and survival of the globe in cases of retained IOFB in the posterior eye segment. Materials and methods: A hospital based retrospective observational study was conducted. All the patients of retained IOFB in the posterior segment presented from January 2016 to June 2019 were enrolled. Patients presented with visual acuity of NPL were excluded. Statistical analysis was performed using a variety of tests using SPSS version 21.   Results: Forty eyes of 40 patients were included. The mean age was 27.08±10.68 years (range 5-66). 95% of our patients were male. Most of them (52.5%) worked on the farm. 26(65%) of 40 eyes had Zone I injury. The median time spent before presentation was 13.5 day. Retinal detachment, vitreous hemorrhage, and endophthalmitis were present in 15, 23 and 5 eyes, respectively, before IOFB removal. The mean LogMAR visual acuity was improved significantly from 2.50±0.87 to 1.33± 1.01 (p=0.003). Poor presenting visual acuity, retinal detachment and large diameter of IOFB were found as the predictor of poor final visual acuity. Conclusion:  Pars plana vitrectomy by a vitreo retinal surgeon can give encouraging results in the cases of retained posterior segment IOFB. Poor presenting visual acuity, large diameter of IOFB and RD before IOFB removal are predictors of poor visual outcome.

Purpose: To describe a surgical technique and report visual and anatomical outcomes after primary combined pars plana vitrectomy (PPV) and phacoemulsification in patients with posterior segment intraocular foreign bodies (IOFBs) removed via the anterior chamber without enlarging preexisting sclerotomies. Posterior IOFBs are generally managed in a stepwise surgery consisting of phacoemulsification/lensectomy for traumatic cataract removal then PPV and removal of IOFB through enlarged sclerotomies. Enlarged sclerotomies may carry a significant risk of hypotony, vitreous hemorrhage, vitreous and retinal incarceration, and rhegmatogenous retinal detachment with proliferative vitreoretinopathy. Limited studies exist on long-term results of primary anterior segment removal of posterior IOFB combined with primary phacoemulsification. Methods: Medical records of consecutive patients who had ocular lacerations and posterior segment IOFB between October 2003 and June 2017 in a university hospital were reviewed. Patients who received a combined primary IOFB removal and phacoemulsification were included in the study. The postoperative evolution including visual acuity and complications were all recorded. Results: Thirteen patients (13 eyes) were included in the study. All patients were men, and the average age at presentation was 38 years. All IOFB were metallic, and their size ranged from 2 to 7 mm. All patients were operated within 24 hours of presentation. Six (46%) of the 13 lacerations were corneal, and 7 (54%) were scleral. Overall, 9 of 13 (69%) had a final postoperative best-corrected visual acuity equal to or better than 20 of 25. There were 3 (23%) postoperative complications of recurrent rhegmatogenous retinal detachment that occurred within the first postoperative year. Conclusion: Primary combined PPV and phacoemulsification with the removal of IOFB via the anterior segment is a safe and promising approach for repairing open globe injuries. Our results demonstrate the favorable prognostic benefit of this technique, which is recommended in cases with small corneal laceration and posterior segment pathology resulting from IOFB.
