Retinal Complications

Tube shunt complications of the retina and vitreous can threaten vision. It is important to understand how to recognize, prevent, and manage these complications. While many retrospective studies regarding retinal complications of tube shunts are in the literature, there are now 2 major prospective studies that can be looked to for the incidence of retinal complications. In the Tube Versus Trabeculectomy (TVT) Study, at 3 years of follow-up, 4 eyes out of 107 total eyes (4%) with tube shunts had required pars plana vitrectomies due to a retinal complication (e.g., vitreous occlusion of the tube, retinal detachment, choroidal detachment). Drainage of a choroidal effusion was performed in 2 patients. Early postoperative retinal complications (onset at 1 month or less after tube shunt implantation) included choroidal effusion (15 eyes; 14%), suprachoroidal hemorrhage (2 eyes; 2%), and vitreous hemorrhage (1 eye; 1%). Late postoperative retinal complications (onset more than 1 month after tube shunt implantation) included choroidal effusion (2 eyes; 2%) and retinal detachment (1 eye; 1%). In the Ahmed Baerveldt Comparison (ABC) Study, at one year of follow-up, one eye of 276 total eyes (0.4%) required a pars plana vitrectomy to clear a postoperative hemorrhage and one eye (0.4%) required reoperation for drainage of a suprachoroidal hemorrhage. Early postoperative retinal complications (3 months of less after implantation of the tube shunt) reported included choroidal effusion (34 eyes; 12%), suprachoroidal hemorrhage (2 eyes; 1%), endophthalmitis (1 eye; 0.4%), and vitreous hemorrhage (5 eyes; 2%). Late retinal postoperative complications (more than 3 months after tube shunt implantation) included choroidal effusion (3 eyes; 1%), endophthalmitis (2 eyes; 1%), vitreous hemorrhage (3 eyes; 1%), and retinal detachment (2 eyes; 1%). Both of these studies indicate a similar incidence of retinal complications after tube shunt implantation. Tube shunt surgery is performed in cases of uncontrolled glaucoma where medications are inadequate. A pars plana tube is most often indicated for anatomic reasons, such as a small eye, or an eye that already has coexisting corneal disease.

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.

The migration of an encircling silicone band through a rectus muscle is a rare postoperative complication associated with scleral buckling surgery for retinal detachment. In this present study, we describe what we believe to be the first reported case of a patient who experienced postoperative migration of an encircling silicone band through the rectus muscle, despite the band being surgically secured to the sclera in a scleral tunnel. A 58-year-old man presented with a rhegmatogenous retinal detachment in his left eye. Pars plana vitrectomy was performed with the placement of an encircling silicone band, and the patient’s retina was successfully reattached. One year postoperatively, the encircling band became exposed on the nasal side of the conjunctiva next to the limbus without any symptoms. Two weeks later, the exposed encircling band was surgically removed without any complications. The findings of this study show that even when an encircling silicone band is surgically secured around the eye, periodic and careful postoperative follow-up examinations should be performed to ensure no migration of the band.

Silicone tube shunt operations to drain the aqueous from the anterior chamber to thesuprachoroidal space were performed in 12 different types of refractory glaucomas inwhich the intraocular pressure ranged from 25 mmHg to 80 mmHg (mean 45.75 mmHg)even after maximally tolerated medical treatment or after conventional glaucomasurgery. The post-silicone tube shunt intraocular pressure ranged from 7 mmHg to 34mmHg (mean 15. 83 mmHg) after a follow-up period ranging 2 months in some casesto 24 months in others. The intraocular pressure was controlled in all casespostoperatively either with the operation alone or with medical treatment or afterrepeat operation. The complications were very few except in one case in which therewas hyphema as well as vitreous hemorrhage prior to operation because of trauma forwhich pars plana vitrectomy followed by second silicone tube shunt operation wereperformed and at the end enucleation had to be done.Key Words: Artificial Drainage, Shunt Operation, Recalcitrant Glaucomas.

<b><i>Background:</i></b> Endoscopic third ventriculostomy (ETV) is currently considered as an alternative to cerebrospinal fluid (CSF) shunt systems in the treatment of obstructive hydrocephalus. This procedure allows the CSF to drain in the basal cisterns and reabsorbed by arachnoid granulations, and avoiding implantation of exogenous material. <b><i>Aims and Objectives:</i></b> The purpose of this study was to assess the success rate of ETV in infants less than 1 year of age with congenital noncommunicating hydrocephalus. <b><i>Material and Methods:</i></b> This study was a 2-year prospective study from August 2017 to July 2019. ETVs were performed in 14 patients younger than 1 year with diagnosis of noncommunicating hydrocephalous. A failure was defined as the need for shunt implantation after ETV. Phase-contrast MRI of the brain was done after 6 months to see patency of ETV fenestration and CSF flow through ventriculostomy. <b><i>Results:</i></b> ETV was tried in 18 patients and successfully performed in 14 patients. Out of the 14 patients, shunt implantation after ETV was performed in 3 patients (failed ETV). In the successful cases, etiology was idiopathic aqueductal stenosis in 8, shunt complications in 2, and 1 case was a follow-up case of occipital encephalocele; the mean age was 7.7 months (range 3–12). In the 3 failed cases, etiology was aqueductal stenosis, mean age was 7.6 months (range 3–11). In all ETVs, failed patients MPVP shunting was done. Follow-up of nonshunted patients was done from 6 to 24 months (mean 15 months). There was no mortality or permanent morbidity noted following ETV. <b><i>Conclusion:</i></b> ETV is a good surgical procedure for less than 1-year-old children.

Purpose. To quantify the frequency of visual loss after successful retinal detachment (RD) surgery in macula-on patients in a multicentric, prospective series of RD.Methods. Clinical variables from consecutive macula-on RD patients were collected in a prospective multicentric study. Visual loss was defined as at least a reduction in one line in best corrected visual acuity (VA) with Snellen chart. The series were divided into 4 subgroups: (1) all macula-on eyes (n=357); (2) macula-on patients with visual loss at the third month of follow-up (n=53) which were further subdivided in (3) phakic eyes (n=39); and (4) pseudophakic eyes (n=14).Results. Fifty-three eyes (14.9%) had visual loss three months after surgery (n=39phakic eyes;n=14pseudophakic eyes). There were no statistically significant differences between them regarding their clinical characteristics. Pars plana vitrectomy (PPV) was used in 67.2% of cases, scleral buckle in 57.7%, and scleral explant in 11.9% (36.1% were combined procedures).Conclusions. Around 15% of macula-on RD eyes lose VA after successful surgery. Development of cataracts may be one cause in phakic eyes, but vision loss in pseudophakic eyes could have other explanations such as the effect of released factors produced by retinal ischemia on the macula area. Further investigations are necessary to elucidate this hypothesis.

Aim: To assess long-term anatomic and functional outcomes of early lens-sparing vitrectomy (LSV) for stage 4A retinopathy of prematurity (ROP) in infants with aggressive-posterior ROP (AP-ROP) which progressed to retinal detachment despite laser treatment. Methods: Chart review of infants who underwent early 25-gage LSV for stage 4A ROP. Outcomes were anatomic success, mean visual acuity (VA), development of postoperative complications, and refractive changes. Follow-up examinations were performed at 1, 3, 6, 12, and then every 6 months. Results: Ten eyes of seven preterm infants who underwent LSV were included. Mean follow-up was 36 ± 13.4 months and mean postmenstrual age (PMA) at last follow-up was 37 ± 13.7 months. Mean gestational age (GA) and weight at birth was 26 ± 1.4 weeks and 639 ± 180 g. Two eyes had vitreous hemorrhage 4 and 14 days after surgery, respectively. At last follow-up anatomic success was 100%, mean VA was 20/80 and eight eyes (80%) had high myopic refractive correction (mean spherical equivalent –11.25 D). Conclusion: Early LSV for stage 4A ROP with AP-ROP and progression to retinal detachment is efficacious in terms of anatomic and functional outcomes. Anatomic success is associated with visual improvement despite possible myopic refraction changes during follow-up.

Purpose: This article reports the clinical features, associations, and outcomes of patients with full-thickness macular hole (MH) formation after pars plana vitrectomy for retinal detachment (RD). Methods: A retrospective, interventional case series is presented of consecutive patients undergoing surgical repair of MH following prior tractional or rhegmatogenous retinal detachment repair from September 2014 to October 2018 at a single vitreoretinal surgery practice. The size of the MH, presence of epiretinal membrane (ERM), rate of MH closure, and visual outcome following repair were evaluated. Results: A total of 996 cases of rhegmatogenous and tractional retinal detachment repair were identified. The average time from the RD surgery to MH diagnosis was 72 days. The incidence of subsequent MH formation in patients who underwent surgery was 0.8% (8/996). The presence of ERM prior to MH repair was noted in 50% of these cases (4/8). In cases with at least 3 months of postoperative follow-up, MH closure was achieved in 100% of eyes after a single surgery. The mean preoperative visual acuity (VA) was 2.06 logMAR (logarithm of the minimum angle of resolution) units (Snellen equivalent, 20/2296) and significantly improved to 0.72 logMAR units (Snellen, 20/104; P = .017) at the last follow-up after MH repair. All patients had improvement in VA at the final postoperative visit, with a VA of 20/200 or better achieved in 87.5% of cases. Conclusions: Although MH formation after successful RD repair is uncommon, favorable visual and anatomic results can be obtained.

Abstract Background The recurrence of retinal detachment (RD) following rhegmatogenous retinal detachment (RRD) is a relatively common complication that threatens vision and needs further surgery. The purpose of this study is to investigate the risk factors and visual outcomes of recurrent RD following pars plana vitrectomy (PPV) for primary RRD.Methods This was a retrospective follow-up of 343 eyes that underwent initial PPV surgery for primary RRD. Patients were divided into a recurrence group and a reattachment group. The main outcome measures included the causative factors, visual outcomes of RD recurrence, and the perioperative factors most affecting the recurrence of RD.Results After retinal reattachment, we observed recurrence of RD after PPV for primary RRD in 42 out of 343 eyes (12.2%) during the follow-up period. Most recurrence (69%) occurred within 6 months after surgery. Univariate analysis showed that the primary risk factor significantly associated with recurrent RD was the presence of proliferative vitreoretinopathy (PVR) ≥ Grade C ( P = 0.003). Logistic regression analysis showed that a PVR ≥ Grade C (odds ration [OR]: 9.421, 95% confidence interval [CI]: 2.432 - 56.39; P =0.020) was a significant predictor for the development of recurrent RD. The recurrence of RD resulted in a significant decline in best-corrected visual acuity (BCVA) at the last follow-up visit compared with the reattachment group ( P =0.000). Eyes with PVR prior to primary surgery or at the diagnosis of re-detachment showed a worse final BCVA.Conclusions The presence of PVR ≥ Grade C was the predominant risk factor for the recurrence of RD. PVR prior to primary surgery, or at the diagnosis of re-detachment, limited the recovery of final visual acuity.

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.
