SURGICAL OUTCOMES IN CONCURRENT SICKLE CELL AND DIABETIC RETINOPATHY.

PURPOSE: To report the clinical features and outcomes in eyes that underwent vitreoretinal surgery for complications of concurrent sickle cell retinopathy and diabetic retinopathy. METHODS: Retrospective, consecutive case series of all eyes that underwent vitreoretinal surgery for complications secondary to concurrent sickle cell retinopathy and diabetic retinopathy between January 01, 2014, and December 31, 2021. RESULTS: The study included 20 eyes of 14 patients. Indications for surgery included tractional retinal detachment in 12 eyes (60%), combined tractional retinal detachment/rhegmatogenous retinal detachment in 6 eyes (30%), and vitreous hemorrhage in 2 eyes (10%). Pars plana vitrectomy was performed in all eyes. One eye received a scleral buckle at the same time as pars plana vitrectomy. There was no change in mean best-corrected visual acuity at the last follow-up examination (1.5 [20/678]) when compared with mean preoperative best-corrected visual acuity (1.6 [20/762], P = 0.83). Preoperative best-corrected visual acuity correlated with postoperative best-corrected visual acuity at the last follow-up examination in eyes with retinal detachment (r = 0.49, P = 0.04). Single operation anatomic success was achieved in 11 of 17 eyes (65%) with retinal detachment. CONCLUSION: Functional and anatomic outcomes after surgery in eyes with concurrent sickle cell retinopathy and diabetic retinopathy are relatively poor.

Comparison in Retreatments between Bevacizumab and Ranibizumab Intravitreal Injections for Retinopathy of Prematurity: A Multicenter Study.

PURPOSE: To compare the types and dosages of anti-vascular endothelial growth factors (VEGFs) to ascertain whether specific dosages or types of injection were associated with retreatment in clinical practice in the United States. DESIGN: Multicenter, retrospective, consecutive series. PARTICIPANTS: Patients with retinopathy of prematurity (ROP) treated with anti-VEGF injections from 2007 to 2021. METHODS: Sixteen sites from the United States participated. Data collected included demographics, birth characteristics, examination findings, type and dose of anti-VEGF treatment, retreatment rates, and time to retreatment. Comparisons of retreatment rates between bevacizumab and ranibizumab intravitreal injections were made. MAIN OUTCOME MEASURES: Relative rate of retreatment between varying types of anti-VEGF therapy, including bevacizumab and ranibizumab, and the various dosages used for each. RESULTS: Data from 873 eyes of 661 patients (61% male and 39% female) were collected. After exclusion of 40 eyes treated with laser before anti-VEGF injection and 266 eyes re-treated with laser at or beyond 8 weeks after the initial anti-VEGF treatment, 567 eyes of 307 patients (63% male and 37% female) remained and were included in the primary analysis. There was no difference between the no retreatment and retreatment groups in terms of birthweight, gestational age, age at first injection, ROP stages, or number of involved clock hours. The retreatment group had a larger percentage of aggressive ROP (34% vs. 18%, P < 0.001) and greater percentage of zone 1 ROP (49 vs. 34%, P = 0.001) than the no retreatment group. Ranibizumab use was associated with a higher rate of retreatment than bevacizumab use (58% vs. 37%, P < 0.001), whereas the rate of retreatment was not associated with a specific dose of ranibizumab (R2 = 0.67, P = 0.32). Meanwhile, lower doses of bevacizumab were associated with higher rates of retreatment compared with the higher doses (R2 = 0.84, P = 0.01). There was a dose-specific trend with higher doses trending toward lower retreatments for bevacizumab. CONCLUSIONS: In a multicenter study of ROP patients initially treated with anti-VEGF therapy, ranibizumab and lower-dose bevacizumab use were associated with an increased rate of retreatment when compared with higher-dose bevacizumab.

27-GAUGE PARS PLANA/PLICATA VITRECTOMY FOR PEDIATRIC VITREORETINAL SURGERY.

PURPOSE: To report on the feasibility of 27-gauge (G) vitrectomy for pediatric patients. METHODS: This study is an international, multicenter, retrospective, interventional case series. Participants were patients 17 years or younger who underwent 27-G vitrectomy for various indications. RESULTS: The records of 56 eyes from 47 patients were reviewed. Mean age was 5.7 ± 5.2 years. Diagnoses included retinopathy of prematurity (Stages 3 with vitreous hemorrhage, 4A, 4B, and 5), Terson's syndrome, traumatic macular hole, posterior capsular opacification, endophthalmitis, and others. Instruments used were the 27-G infusion, 27-G vitreous cutter, 27-G light pipe, and 27-G internal limiting membrane forceps. Instrument bending was noted in one (1.8%) case. There were no cases with intraoperative complications, infusion issues, or postoperative endophthalmitis. There were 67/145 (46%) sclerotomies that required suturing, of which most (51/145) were sutured out of precaution. There were four cases (7.1%) that required conversion to a larger gauge and three cases (5.3%) that developed postoperative hypotony. Mean visual acuity improved from logarithm of the minimum angle of resolution 1.32 (20/420) to 0.72 (20/105), after a mean follow-up of 125.1 days (P = 0.01). Anatomic success was achieved in 96.4% of eyes after a single surgery. CONCLUSION: Twenty-seven-gauge vitrectomy was safe and feasible in selected pediatric vitreoretinopathies. Further studies are warranted to examine indications and outcomes.

Practice Patterns and Outcomes of Intravitreal Anti-VEGF Injection for Retinopathy of Prematurity: An International Multicenter Study.

PURPOSE: To report practice patterns of intravitreal injections of anti-VEGF for retinopathy of prematurity (ROP) and outcomes data with a focus on retreatments and complications. DESIGN: Multicenter, international, retrospective, consecutive series. SUBJECTS: Patients with ROP treated with anti-VEGF injections from 2007 to 2021. METHODS: Twenfty-three sites (16 United States [US] and 7 non-US) participated. Data collected included demographics, birth characteristics, examination findings, and methods of injections. Comparisons between US and non-US sites were made. MAIN OUTCOME MEASURES: Primary outcomes included number and types of retreatments as well as complications. Secondary outcomes included specifics of the injection protocols, including types of medication, doses, distance from limbus, use of antibiotics, and quadrants where injections were delivered. RESULTS: A total of 1677 eyes of 918 patients (43% female, 57% male) were included. Mean gestational age was 25.7 weeks (range, 21.2-41.5 weeks), and mean birth weight was 787 g (range, 300-2700 g). Overall, a 30-gauge needle was most commonly used (51%), and the quadrant injected was most frequently the inferior-temporal (51.3%). The distance from the limbus ranged from 0.75 to 2 mm, with 1 mm being the most common (65%). Bevacizumab was the most common anti-VEGF (71.4%), with a dose of 0.625 mg in 64% of cases. Overall, 604 (36%) eyes required retreatment. Of those, 79.8% were retreated with laser alone, 10.6% with anti-VEGF injection alone, and 9.6% with combined laser and injection. Complications after anti-VEGF injections occurred in 15 (0.9%) eyes, and no cases of endophthalmitis were reported. Patients in the United States had lower birth weights and gestational ages (665.6 g and 24.5 weeks, respectively) compared with non-US patients (912.7 g and 26.9 weeks, respectively) (P < 0.0001). Retreatment with reinjection and laser was significantly more common in the US compared with the non-US group (8.5% vs. 4.7% [P = 0.0016] and 55% vs. 7.2% [P < 0.001], respectively). There was no difference in the incidence of complications between the 2 geographic subgroups. CONCLUSIONS: Anti-VEGF injections for ROP were safe and well tolerated despite a variance in practice patterns. Infants with ROP receiving injections in the US tended to be younger and smaller, and they were treated earlier with more retreatments than non-US neonates with ROP.

GENDER DIFFERENCES IN SELF-REPORTED PROCEDURAL VOLUME AMONG VITREORETINAL FELLOWS.

PURPOSE: A prior study revealed discrepancies in self-reported surgical numbers between male and female ophthalmology residents. This study further investigates the gender differences in self-reported procedural volume among vitreoretinal surgery fellows and examines the differences for surgical, medical, and total self-reported procedural volume between male and female vitreoretinal fellows. METHODS: A retrospective review of case logs submitted to the American Society of Retina Specialists by first-year and second-year vitreoretinal fellows from July 1, 2018, to June 30, 2019, was performed. Fellows who reported fewer than 100 pars plana vitrectomies were excluded. A total of 133 fellows were included. RESULTS: Overall, 37 of 57 (65%) first-year fellows and 59 of 76 (78%) second-year fellows were male. An average of 1,120 procedures were self-reported among all vitreoretinal fellows. In the group of second-year fellows at the completion of fellowship, men reported more total procedures (1,171 [864-1,600] vs. 1,005 [719-1,257]; P = 0.072). Women reported statistically significant fewer endolaser (P = 0.018), internal limiting membrane peel (P = 0.042), and cryoretinopexy (P = 0.002) procedures compared with men. When splitting the data by total surgical versus medical procedures, men reported more procedures than women both surgically (1,077 [799-1,490] vs. 925 [622-1,208]; P = 0.085) and medically (72 [41-116] vs. 56 [20-94]; P = 0.141), although these differences were not statistically significant. CONCLUSION: There is a trend for female vitreoretinal fellows to report fewer surgical procedures than their male counterparts, raising concerns for gender gaps in vitreoretinal surgical training. Further research is needed to verify this discrepancy and identify potential barriers that female vitreoretinal surgeons are facing in training.

Case Series: Small Full-thickness Macular Hole Treated with Topical Dorzolamide and Bevacizumab Intravitreal Injections.

SIGNIFICANCE: This article reports two cases reported of combined treatment with topical dorzolamide and intravitreal bevacizumab injections, successfully treating small full-thickness macular hole without the need for traditional macular hole surgery. PURPOSE: This study aimed to report the potential effectiveness of combination treatment with topical dorzolamide and bevacizumab intravitreal injection therapy for small macular holes. CASE REPORTS: Case 1 was a 68-year-old woman presented with distorted and decreased vision in her right eye for 9 months. Fundus examination showed a full-thickness macular hole, which was confirmed with spectral domain optical coherence tomography measuring 96 µm. Treatment with topical dorzolamide and intravitreal bevacizumab 1.25 mg/0.05 mL injections was initiated. Spectral domain optical coherence tomography showed gradual improvement of the full-thickness macular hole with complete hole closure and visual improvement in just 1 month. Case 2 was a 73-year-old woman who presented with distorted and decreased vision in her right eye for 8 months. Fundus examination showed a full-thickness macular hole in the right eye, confirmed with spectral domain optical coherence tomography, measuring 76 µm. Treatment with topical dorzolamide and intravitreal bevacizumab 1.25 mg/0.05 mL injections was initiated. Spectral domain optical coherence tomography showed gradual improvement of the full-thickness macular hole with complete closure at 2 months and improvement in visual acuity. CONCLUSIONS: The combination of topical dorzolamide and bevacizumab intravitreal injection is a reasonable consideration for small macular holes with vascular components before considering surgery. Both cases had early macular closure in less than 3 months.

Case Report: Endogenous Candida Endophthalmitis in Cornelia de Lange Syndrome: Atypical Stellate Neuroretinitis.

SIGNIFICANCE: This study aimed to highlight the association of stellate neuroretinitis occurring secondary to endogenous candidemia. PURPOSE: We report an unusual presentation of endogenous Candida endophthalmitis as a stellate neuroretinitis in the setting of Cornelia de Lange syndrome. CASE REPORT: A 34-month-old girl with severe Cornelia de Lange syndrome and a history of parenteral nutrition dependence requiring a chronic central venous catheter presented with bilateral endophthalmitis secondary to candidemia. In one eye, the endophthalmitis had the atypical presentation as a stellate neuroretinitis. CONCLUSIONS: This case represents a unique association of stellate neuroretinitis secondary to Candida infection in a patient with Cornelia de Lange syndrome.

ANALYSIS OF THE VITREORETINAL SURGICAL FELLOWSHIP APPLICANT POOL: Publication Misrepresentations and Predictors of Future Academic Output.

PURPOSE: To evaluate characteristics associated with misrepresentation of publication record, future career placement, and subsequent academic output among vitreoretinal surgical fellowship applicants. METHODS: A retrospective review of 337 vitreoretinal surgical applicants between 2015 and 2018 was conducted. Publications reported in the applications were verified using PubMed, Google, and Google Scholar. Applications were considered misrepresented if there was no record of the publication or if there was an inconsistency in authorship. Applicants were followed after graduation and their employment position and postgraduation publications were recorded. The main outcome measures were the number of unverifiable publications, postfellowship job placement, and postgraduate peer-reviewed publications. RESULTS: Of the 377 applicants, 309 (82.0%) listed peer-reviewed publications. Of those with a publication, 32 (10.4%) had misrepresentations. A reported desire to pursue an academic career was associated with a future career in academic medicine, whereas Alpha Omega Alpha status was correlated with a future career in private practice. Alpha Omega Alpha status, a reported desire to pursue an academic career, and the number of peer-reviewed publications before fellowship were positively correlated with higher numbers of peer-reviewed publications after fellowship. CONCLUSION: Unverifiable authorship among vitreoretinal surgical fellowship applicants is significant, affecting nearly one in 10 applicants with peer-reviewed publications. A reported desire to pursue academic medicine as listed on the fellowship application is a useful indicator for a future career in academics, and for increased number of peer-reviewed publications after fellowship.

Acute Orbital Compromise after Intra-Arterial Chemotherapy in a Complex Retinoblastoma Associated with 13q Deletion Syndrome.

INTRODUCTION: The intra-arterial chemotherapy (IAC) is increasingly used as a first-line therapy for retinoblastoma. The IAC has proved to be relatively safe. However, many local side effects of IAC have been described. CASE PRESENTATION: This case report describes a local side effect presenting as proptosis and myositis with vascular access difficulty of the middle meningeal artery, in a 2-year-old male with left eye diffuse multifocal stage Vb retinoblastoma complicated with retinal detachment. DISCUSSION/CONCLUSION: IAC is assured to provide as efficient results in eliminating the tumor as the systemic chemotherapy, without causing the systemic side effects. It has become an alternative to systemic chemotherapy. A better understanding of the local side effects is required.

Impact of Total Pars Plana Vitrectomy on Postoperative Complications in Aphakic, Snap-On, Type 1 Boston Keratoprosthesis.

PURPOSE: To determine the impact of total pars plana vitrectomies (PPVs) with peripheral shaving of the vitreous base on the rates of postoperative complications in patients with aphakic, snap-on type I Boston keratoprostheses (KPros). DESIGN: Retrospective, consecutive case series. PARTICIPANTS: A total of 48 eyes in 46 patients with implantation of aphakic, snap-on type 1 Boston KPros performed at a tertiary care facility between January 1, 2007, and December 31, 2013, were included. METHODS: The cumulative incidences of postoperative complications were compared between patients who underwent total PPVs with shaving of the vitreous base (n = 22) and those who had partial PPVs or anterior vitrectomies (AVs) at the time of KPro implantation (n = 26). MAIN OUTCOME MEASURES: Rates of complications between patients who underwent total PPVs and partial PPVs or AVs. RESULTS: The rate of total postoperative complications was lower in the total PPV group (P = 0.018, log-rank test). In particular, eyes that underwent total PPVs had lower rates of retroprosthetic membranes (RPMs) requiring intervention (P = 0.049) and less vision loss due to glaucoma progression (P = 0.046). There was also a trend for fewer corneal melts (P = 0.060) and less sight-threatening complications (P = 0.051) in the total vitrectomy group. There was no difference in the rates of KPro extrusion (P = 0.41), endophthalmitis or vitritis (P = 0.15), retinal detachments (P = 0.76), cystoid macular edema (P = 0.83), or timing of complications between the 2 groups. The mean preoperative and postoperative visual acuities were similar between the 2 groups (P = 0.97). The mean follow-up was 49±22 months. CONCLUSIONS: Eyes that underwent total PPVs during implantation of aphakic, snap-on, type I Boston KPros had less postoperative complications than eyes with partial PPVs or AVs during the average 4 years of follow-up.

Immediate Sequential Bilateral Pediatric Vitreoretinal Surgery: An International Multicenter Study.

PURPOSE: To determine the feasibility and safety of bilateral simultaneous vitreoretinal surgery in pediatric patients. DESIGN: International, multicenter, interventional, retrospective case series. PARTICIPANTS: Patients 17 years of age or younger from 24 centers worldwide who underwent immediate sequential bilateral vitreoretinal surgery (ISBVS)-defined as vitrectomy, scleral buckle, or lensectomy using the vitreous cutter-performed in both eyes sequentially during the same anesthesia session. METHODS: Clinical history, surgical details and indications, time under anesthesia, and intraoperative and postoperative ophthalmic and systemic adverse events were reviewed. MAIN OUTCOME MEASURES: Ocular and systemic adverse events. RESULTS: A total of 344 surgeries from 172 ISBVS procedures in 167 patients were included in the study. The mean age of the cohort was 1.3±2.6 years. Nonexclusive indications for ISBVS were rapidly progressive disease (74.6%), systemic morbidity placing the child at high anesthesia risk (76.0%), and residence remote from surgery location (30.2%). The most common diagnoses were retinopathy of prematurity (ROP; 72.7% [P < 0.01]; stage 3, 4.8%; stage 4A, 44.4%; stage 4B, 22.4%; stage 5, 26.4%), familial exudative vitreoretinopathy (7.0%), abusive head trauma (4.1%), persistent fetal vasculature (3.5%), congenital cataract (1.7%), posterior capsular opacification (1.7%), rhegmatogenous retinal detachment (1.7%), congenital X-linked retinoschisis (1.2%), Norrie disease (2.3%), and viral retinitis (1.2%). Mean surgical time was 143±59 minutes for both eyes. Higher ROP stage correlated with longer surgical time (P = 0.02). There were no reported intraoperative ocular complications. During the immediate postoperative period, 2 eyes from different patients demonstrated unilateral vitreous hemorrhage (0.6%). No cases of endophthalmitis, choroidal hemorrhage, or hypotony occurred. Mean total anesthesia time was 203±87 minutes. There were no cases of anesthesia-related death, malignant hyperthermia, anaphylaxis, or cardiac event. There was 1 case of reintubation (0.6%) and 1 case of prolonged oxygen desaturation (0.6%). Mean follow-up after surgery was 103 weeks, and anatomic success and globe salvage rates were 89.8% and 98.0%, respectively. CONCLUSIONS: This study found ISBVS to be a feasible and safe treatment paradigm for pediatric patients with bilateral vitreoretinal pathologic features when repeated general anesthesia is undesirable or impractical.

Terson's Syndrome in a Patient with von Hippel-Lindau Disease.

PURPOSE: Terson's syndrome is a condition where a preretinal hemorrhage forms as a result of increased intracranial pressure. The elevated intracranial pressure is thought to be transmitted through the veins and the optic nerve sheath to the optic disc and retina, causing the thin capillary walls to rupture. The authors present a unique case of Terson's syndrome in a patient who underwent recent surgical management for cerebellar hemangioblastomas related to von Hippel-Lindau disease. CASE REPORT: A 17-year-old African American female patient with a history of von Hippel-Lindau disease presented with pain in her right eye. She had recently undergone surgery to remove cerebellar hemangioblastomas. Preliminary fundus imaging was performed, but before formal ophthalmic testing could be conducted, the patient seized and was taken directly to the emergency room. When the patient returned for a formal evaluation 3 weeks later, a new preretinal "boat-shaped" hemorrhage was now present. Additionally, reports from the emergency room suggested that she had bled into the cavity where the previous cerebellar resection had taken place. This hemorrhage likely led to an increase in intracranial pressure, causing a Terson's-like event. CONCLUSIONS: A Terson's event may be caused by high intracranial pressure secondary to the surgical removal of von Hippel-Lindau syndrome-associated cerebellar tumors and should be included as a possible complication of surgical management.

Influence of Fluorescein Angiography on the Diagnosis and Management of Retinopathy of Prematurity.

PURPOSE: To examine the influence of fluorescein angiography (FA) on the diagnosis and management of retinopathy of prematurity (ROP). DESIGN: Prospective cohort study. PARTICIPANTS: Nine recognized ROP experts (3 pediatric ophthalmologists and 6 retina specialists) interpreted 32 sets (16 color fundus photographs and 16 color fundus photographs paired with the corresponding FA images) of wide-angle retinal images from infants with ROP. METHODS: All experts independently reviewed the 32 image sets on a secure website and provided a diagnosis and management plan for the case presented, first based on color fundus photographs alone, and then based on color fundus photographs and corresponding FA images. MAIN OUTCOME MEASURES: Sensitivity and specificity of the ROP diagnosis (zone, stage, plus disease, and category, i.e., no ROP, mild ROP, type 2 ROP, and ROP requiring treatment) were calculated using a consensus reference standard diagnosis, determined from the diagnosis of the color fundus photographs by 3 experienced readers in combination with the clinical diagnosis based on ophthalmoscopic examination. The κ statistic was used to analyze the average intergrader agreement among experts for the diagnosis of zone, stage, plus disease, and category. RESULTS: Addition of FA to color fundus photography resulted in a significant improvement in sensitivity for diagnosis of stage 3 or worse disease (39.8% vs. 74.1%; P = 0.008), type 2 or worse ROP (69.4% vs. 86.8%; P = 0.013), and pre-plus or worse disease (50.5 vs. 62.6%; P = 0.031). There was a nonsignificant trend toward improved sensitivity for diagnosis of ROP requiring treatment (22.2% vs. 40.3%; P = 0.063). Using the κ statistic, addition of FA to color fundus photography significantly improved intergrader agreement for diagnosis of ROP requiring treatment. Addition of FA to color fundus photography did not affect intergrader agreement significantly for the diagnosis of stage, zone, or plus disease. CONCLUSIONS: Compared with color fundus photography alone, FA may improve the sensitivity of diagnosis of ROP by experts, particularly for stage 3 disease. In addition, intergrader agreement for diagnosis of ROP requiring treatment may improve with FA interpretation.

EPITHELIAL DOWNGROWTH IN THE VITREOUS CAVITY AND ON THE RETINA IN ENUCLEATED SPECIMENS AND IN EYES WITH VISUAL POTENTIAL.

PURPOSE: To report clinical course and visual and anatomical outcomes of six eyes with histopathologically confirmed vitreous cavity and retina epithelial downgrowth. METHODS: This is a retrospective 15-year review of archived pathologic slides and corresponding medical records of patients with vitreous cavity and retina epithelial downgrowth. Posterior segment epithelial downgrowth was defined as epithelial or goblet cells in the vitreous cavity or on the surface of the retina. RESULTS: Histopathologic diagnosis of epithelial downgrowth was made in 122 patients. Of those, 6 patients (5%) had vitreous cavity and retina epithelial downgrowth. Three patients developed blind painful eye, and epithelial downgrowth was identified in enucleated specimens. The other three eyes with visual potential presented with tractional retinal detachments. Epithelial downgrowth was identified in epiretinal membranes obtained during pars plana vitrectomy. The latter group had more previous surgeries (P = 0.03), and all had keratoprosthesis implantation as their last surgery. All three had pathologic specimens obtained at the time of the keratoprosthesis implantation; no anterior segment epithelial downgrowth was noted in two patients, and one patient had involvement of corneal button, iris, and posterior capsule. Final visual acuity ranged from hand motion to light perception. CONCLUSION: In the current study, vitreous cavity and retina epithelial downgrowth occurred after multiple intraocular surgeries, including repair of the open globe injuries both in enucleated specimens and in eyes with visual potential. In eyes with visual potential, keratoprosthesis implantation seems to predispose the development of posterior segment epithelial downgrowth.

Peripheral retinal vasculopathy in childhood glaucoma.

PURPOSE: To report wide-field fluorescein angiography findings in the peripheral retina of eyes with childhood glaucoma. METHODS: Fluorescein angiograms were examined retrospectively in 12 patients with childhood glaucoma who underwent wide-field fluorescein angiography after surgical or medical treatment of glaucoma. This series included 12 eyes of 6 patients with primary congenital glaucoma, 5 eyes of 3 patients with glaucoma associated with congenital cataract surgery, 4 eyes of 2 patients with glaucoma associated with a systemic condition, and 1 eye of 1 patient with phakomatosis pigmentovascularis Type II. RetCam fundus photography images and digital fluorescein angiography were performed under general anesthesia. RESULTS: The most common finding observed in our series was peripheral retinal nonperfusion, which affected 20 eyes (91%). Other notable features seen were circumferential branching of the retinal vessels parallel to the ora serrata (77%), venous shunts (50%), and abnormal capillary branching patterns, including capillary dilatation (41%) and tortuous capillary tangles (18%). Leakage at the junction of vascular and avascular retina was not commonly seen (13.6%). None of the eyes had evidence of retinal neovascularization or fibrovascular proliferation. CONCLUSION: Retinal vascular abnormalities and peripheral nonperfusion are novel findings in childhood glaucoma. Further studies are needed to understand the significance and possible long-term consequences of these findings.

Exudative retinal detachment following photocoagulation in older premature infants for retinopathy of prematurity: description and management.

PURPOSE: To describe exudative retinal detachment following laser photocoagulation after 40 weeks of postmenstrual age (PMA) for retinopathy of prematurity in premature infants, its medical management, and outcomes. METHODS: Two pediatric vitreoretinal surgeons at 2 different quaternary care institutions retrospectively identified children who received laser photocoagulation after 40 weeks of PMA and subsequently developed exudative detachment. Hospital course, management, and outcomes were identified. RESULTS: Three infants were identified that developed exudative retinal detachments following laser photocoagulation for retinopathy of prematurity after 40 weeks of PMA. The average gestational age was 25 weeks with an average birth weight of 650 g. All babies were Zone II at initial examination and developed Stage 3 with pre-plus or plus disease after 40 weeks of PMA (average 42 weeks of PMA). Therapy consisted of topical cyclogyl (0.5%) and topical prednisolone acetate (1%) to the affected eyes and intravenous dexamethasone in all cases. The exudative retinal detachments resolved by 50 weeks of PMA in all infants. Hard exudates following resolution were found in all eyes. Two eyes demonstrated temporal macular dragging. CONCLUSION: Premature infants who require laser photocoagulation for retinopathy of prematurity at >40 weeks of PMA may be predisposed to develop exudative retinal detachments. In the absence of identifiable traction, systemic corticosteroid use can be considered to achieve favorable anatomic outcomes.

Endophthalmitis caused by Achromobacter xylosoxidans after cataract surgery.

PURPOSE: To report Achromobacter xylosoxidans as a cause of both acute-onset and delayed-onset postoperative endophthalmitis after cataract surgery. METHODS: A noncomparative consecutive case series of patients with culture-proven A. xylosoxidans endophthalmitis between 1970 and 2012. Cataract surgery and intraocular lens placement were performed in all patients before endophthalmitis. Positive cultures were obtained from the vitreous, capsular bag, and/or the removed intraocular lens. RESULTS: The clinical diagnosis was confirmed in four patients with positive cultures. Two patients with endophthalmitis had a preliminary culture report of Pseudomonas species. In addition to receiving intravitreal antibiotics, all patients underwent capsulectomy and intraocular lens removal at the time of pars plana vitrectomy. Visual acuity at last follow-up was 20/40 or better in 2 (50%) of the 4 patients, but the remaining 2 patients were 20/200 or worse. CONCLUSION: A. xylosoxidans may be a cause of acute, recurrent, and delayed-onset postoperative endophthalmitis after cataract surgery. Complete capsulectomy and intraocular lens removal can be considered in recurrent and recalcitrant patients.
