LONG-TERM USE OF ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY FOR NEOVASCULAR AGE-RELATED MACULAR DEGENERATION.

PURPOSE: Although pivotal trials have demonstrated efficacy of anti-vascular endothelial growth factor therapy in neovascular age-related macular degeneration, there is a paucity of clinical data about the long-term (>5 years) treatment. METHODS: Retrospective analysis of all patients with neovascular age-related macular degeneration who were actively treated, had received >40 anti-vascular endothelial growth factor injections, and were followed for ≥5 years. Snellen-corrected visual acuity, initial drug choice, and times elapsed between treatments were collected. Rates of endophthalmitis and outcomes of submacular hemorrhage were also evaluated. RESULTS: A total of 88 patients (162 eyes) met the inclusion criteria: the average patient age was 86.3 years with an average follow-up period of 7.6 years. The average total number of injections per eye was 69 (18.0 SD); a total of 11,208 injections were given throughout the study period, and 6 cases (0.05%) of endophthalmitis were observed. Overall, there was a clinical and statistical difference in average Snellen-corrected visual acuity at Injections #2,#3, #4, #5, #6, #10, and #20, as compared with baseline ( P = 0.03, P < 0.01, P = 0.02, P < 0.01, P = 0.01, P = 0.01, P < 0.01, respectively). Patients in the Snellen-corrected visual acuity subgroup 20/20 to 20/40 maintained vision until injection #30. Seven eyes experienced a visually significant submacular hemorrhage. CONCLUSION: This neovascular age-related macular degeneration cohort received on average eight anti-vascular endothelial growth factor injections per year for approximately 8 years; eyes with good (≥20/40) initial baseline vision maintained their visual acuity, whereas those with worse Snellen-corrected visual acuity (≤20/50) had a robust initial improvement that diminished with time. Most patients were maintained on the same initial drug of choice and the rate of endophthalmitis was low.

SEVERE RETINAL ISCHEMIA IN INFANT WITH NEUROFIBROMATOSIS TYPE 1.

PURPOSE: To report a case of severe retinal ischemia in an infant with neurofibromatosis type 1. METHODS: Chart review, analysis of imaging studies, and review of literature. RESULTS: A boy born at 37 weeks postmenstrual age with neurofibromatosis type 1 was noted to have a large plexiform neurofibroma with left-sided involvement of the cavernous sinus, internal carotid artery, orbit, and optic nerve. He was managed for left eye glaucoma with anti-hypertensive eye drops, and at 8 months of age, he was referred for retinal evaluation. Fluorescein angiography showed striking nonperfusion of the left retina with only a small area of perfused vessels in the posterior pole. A large frond of neovascularization extended anteriorly from the posterior pole. The right eye had a crescent of retinal nonperfusion in the far periphery but otherwise normal retinal vessels. CONCLUSION: This case demonstrates a severe form of retinal ischemia in the setting of a large neurofibroma because of neurofibromatosis type 1. We hypothesize that vascular compression from the tumor led to disruption of the neurovascular bundle with resultant severe nonperfusion, neovascularization, and retinal maldevelopment.

Outcomes in Retinal Detachment Repair and Laser Prophylaxis for Syndromes with Optically Empty Vitreous.

PURPOSE: To evaluate and compare surgical outcomes for syndromes with optically empty vitreous (SOEV)-associated rhegmatogenous retinal detachments. DESIGN: A retrospective, cross-sectional, 2-arm study of a single pediatric vitreoretinal surgeon's patients from a quaternary referral center with SOEV was performed to examine visual and anatomical outcomes of rhegmatogenous retinal detachment and laser prophylaxis. SUBJECTS: Patients identified either through slit-lamp examination (presence of an optically empty or void space in the vitreous gel structure) or genetic testing. Fifty-six eyes of 49 patients were identified in the retinal detachment arm. Sixty eyes of 48 patients were identified in the laser prophylaxis arm. METHODS: Comparison of initial retinal detachment (RD) surgical repair via pars plana vitrectomy (PPV), scleral buckle (SB), or PPV-SB with final anatomical success, best-corrected visual acuity (BCVA), and number of surgical procedures. Secondary analysis was performed looking at eyes failing their initial SB, eyes with a giant retinal tear at presentation, eyes failing RD repair within specific time intervals, and eyes where hyaloid was elevated during initial vitrectomy. An additional study arm examined the outcomes of final BCVA and the presence and timing of developing a retinal tear or RD in eyes who received laser prophylaxis. MAIN OUTCOME MEASURES: Visual acuity, surgical repair techniques (PPV, SB, PPV-SB), number of surgeries, anatomical retinal reattachment success. RESULTS: Initial SB had statistically significant better final BCVA (P < 0.01) and better final anatomical success (P < 0.01). No statistical difference in the number of surgeries needed to achieve anatomical success between the initial SB versus initial PPV-SB/PPV. Hyaloidal elevation during the initial vitrectomy was associated with improved final BCVA and higher final anatomical success without the use of silicone oil (P < 0.01 and 0.04 respectively). Lastly, eyes that developed RDs after laser prophylaxis had better final BCVA than untreated eyes (P < 0.05). CONCLUSION: Initial SB yields better overall outcomes in SOEV presenting with rhegmatogenous retinal detachment. Stickler Type-1 patients had similar outcomes compared with other SOEV, suggesting both populations should be treated with similar approaches.

Case Series of Progressive Retinal Detachments in Persistent Fetal Vasculature.

PURPOSE: Persistent fetal vasculature (PFV) may be associated with tractional retinal detachment due to tractional contraction of the fibrovascular stalk. PFV is often thought to be congenital and non-progressive. A rhegmatogenous component is far less common and is typically identified as a post-operative complication and has not been spontaneously reported. We present five cases illustrating potential progressive changes and complications that may arise in non-operated PFV. METHODS: A retrospective case series of five patients who presented with progressive retinal detachments from persistent fetal vasculature. RESULTS: Five unique cases of persistent fetal vasculature with significant progression from time of initial presentation, four of which included development of rhegmatogenous components. CONCLUSION: Patients with PFV and a seemingly stable tractional detachment should undergo evaluation with a retina specialist for risk stratification and management, as rhegmatogenous detachments may occur due to ocular growth and stretch breaks, and tractional detachments can continue to progress over time.

Variation in Perioperative Care Practices Among Vitreoretinal Surgeons in the United States.

OBJECTIVE: To describe perioperative practice patterns among retinal surgeons managing retinal detachment (RD) repair. METHODS: This was a cross-sectional pilot survey of vitreoretinal surgeons in the United States (US), identified by a previously published web-based search and cross-referencing names from the American Society of Retina Specialists. Self-reported peri-operative practices and subgroups were analyzed. RESULTS: Of the 298 surgical retina specialists who completed the survey, 115 (39%) were in practice for ≤ 5 years, 102 (34%) were in practice for 6 to 20 years, and 81 (27%) were in practice for > 20 years; 60%, 23%, and 16% were in private, academic, and hybrid practice, respectively. Fifty-nine percent reported operating with trainees. For ocular blocks, 59% perform retrobulbar, 21% peribulbar, and 20% subtenon's (ST). Use of ST block varied significantly by years in practice and presence of trainees (P < 0.0001, P = 0.004, respectively). Sixty percent perform primary scleral buckles (SB), 55% combined SB/pars plana vitrectomy (PPV), and 11% primary PPVs under general anesthesia. Use of general anesthesia for primary SB varied significantly by years in practice (P = 0.007). Surgeons with fewer years in practice were more likely to recommend facedown positioning for macula-off RDs (P < 0.0001). Forty-six percent of surgeons do not advise stopping blood thinners before surgery and this varied significantly by years in practice (P = 0.006). CONCLUSIONS: Variation exists among US vitreoretinal surgeons in relation to anesthesia, postoperative positioning, and blood thinners restrictions. Preferences are influenced by years in practice and less by trainees and practice setting. These results serve as a basis for larger, targeted US-based surveys on perioperative care and correlation with surgical outcomes. [Ophthalmic Surg Lasers Imaging Retina 2022;53:681-690.].

Clinical characteristics and ophthalmic management of a rare disease cohort of patients with trisomy 13.

Trisomy 13 is associated with a variety of ocular findings. As more children with trisomy 13 survive beyond their first year of life, early identification and awareness of associated ocular manifestations is increasingly important. This retrospective case series of 5 patients with trisomy 13 expands on what is known about the complex ocular findings associated with the condition and describes their clinical management, with a mean follow-up of 2 years. All 5 patients had microphthalmos and colobomas of the iris, 4 had corneal opacities, and 2 had kerato-irido-lenticular dysgenesis associated with glaucoma. In addition, these patients were found to have recurrent eyelid infections, congenital glaucoma, cataracts, and persistent fetal vasculature. All 5 patients had cerebral visual impairment.

Application of the Postnatal Growth and Retinopathy of Prematurity (G-ROP) criteria at a tertiary referral hospital.

BACKGROUND: Application of current retinopathy of prematurity (ROP) screening criteria results in many unnecessary examinations, because only 5%-10% of infants screened require treatment. Application of screening criteria established by the Postnatal Growth and Retinopathy of Prematurity Study could significantly reduce unnecessary examinations without sacrificing sensitivity to detect treatment-requiring ROP. We evaluated the performance of the G-ROP criteria in a population of high-risk, outborn infants. METHODS: The medical records of consecutive infants screened and/or treated for ROP at Children's Health Care of Atlanta Hospitals from May 1, 2013, to September 6, 2019, were reviewed retrospectively. The sensitivity of the G-ROP birthweight and gestational age screening criteria to detect treatment-requiring ROP was calculated. RESULTS: During the study period, 901 children underwent examinations for ROP; of these, 5 were excluded from the analysis because birth weight (BW) data was lacking. Of the 896 remaining patients, 120 patients were treated for ROP. Application of G-ROP birth weight and gestational age (GA) criteria alone resulted in a sensitivity of 99.2% to detect infants requiring treatment. Application of weight gain criteria was problematic, because many patients were transferred into our institutions after the specified intervals of 10-19, 20-29, and 30-39 days. CONCLUSIONS: G-ROP BW and GA screening criteria were highly sensitive in detecting treatment-requiring ROP. Applying weight gain criteria in referral centers can be problematic. Intake procedures at referral centers should include documentation of weight gain during 10-19, 20-29, and 30-39 days of life.

Risk Factors for Retinal Detachment in Acute Retinal Necrosis.

PURPOSE: Retinal detachment (RD) is associated with poor visual outcomes in patients with acute retinal necrosis (ARN). This research was undertaken to assess the risk factors for RD in ARN. DESIGN: Retrospective cohort study. SUBJECTS: Patients diagnosed with ARN at a tertiary referral center from 2010 to 2020. METHODS: A chart review was performed for all clinical and surgical encounters. Univariate and multivariate logistic analyses of demographic and clinical variables associated with RD were performed. Survival analyses with Kaplan-Meier estimates were performed to compare the time to RD in herpes simplex virus (HSV)- and varicella zoster virus (VZV)-associated ARN. MAIN OUTCOME MEASURES: Demographic information, clinical information (including visual acuity [VA]), intraocular pressure (IOP), intraocular inflammation level, the extent of retinitis, incidence and timing of retinal detachment, date of diagnosis, and treatments performed (including intravitreal injections of antiviral medications). RESULTS: Fifty-four eyes of 47 patients who were diagnosed with ARN were included, with equal proportions of eyes (n = 27; 50%) with VZV-ARN and HSV-ARN. Patients with VZV-ARN were, on average, older, more likely to be men, and more likely to be immunosuppressed compared with patients with HSV-ARN. The clinical characteristics, including the initial VA, initial IOP, anterior segment inflammation, clock hours, and posterior extent of retinitis, were similar between eyes with VZV- and HSV-ARN. In the univariate analysis of clinical and demographic variables associated with the development of RD, initial VA (P = 0.0083) and greater clock hours of retinitis (P = 0.009) were significantly associated with RD. These 2 variables remained significant in the multivariate logistic regression; worse VA at presentation had an odds ratio of 2.34 (95% confidence interval [CI], 1.01-5.44; P = 0.042), and greater clock hours of retinitis had an odds ratio of 1.23 (95% CI, 1.02-1.47; P = 0.025). A Kaplan-Meier survival analysis demonstrated no statistical difference in RD-free survival between HSV- and VZV-ARN. CONCLUSIONS: Patients with VZV-ARN were more likely to be older, male, and immunosuppressed compared with those with HSV-ARN, although no clear difference was observed in RD by viral etiology. Poor initial VA and clock hours of retinitis were significantly associated with RD development and may be relevant for patient counseling and prognosis.

Etiology, Treatment Patterns, and Outcomes for Choroidal Neovascularization in the Pediatric Population: An Intelligent Research in Sight (IRIS®) Registry Study.

OBJECTIVE: Choroidal neovascularization (CNV) is a rare, but devastating, cause of vision loss in children, with most current publications limited to small case series. Using a large clinical registry allowed us to understand the most common causes of this disease and the visual outcomes. DESIGN: Retrospective analysis. PARTICIPANTS: Patients younger than 18 years in the Intelligent Research in Sight Registry diagnosed with CNV between 2013 and 2019. METHODS: Cases were identified based on International Classification of Diseases, Ninth and Tenth Revisions, diagnosis codes for CNV or CNV-related etiology and Current Procedural Terminology treatment codes. MAIN OUTCOME MEASURES: Etiology of CNV, treatment patterns, and visual outcomes. RESULTS: Two thousand three hundred fifty-three eyes with pediatric CNV were identified. The most common identifiable causes of pediatric CNV were posterior uveitis or inflammatory chorioretinal disease (19.4%), myopia (18.4%), hereditary dystrophy (5.4%), chorioretinal scar (4.2%), choroidal rupture (3.5%), optic nerve drusen (3.2%), osteoma (1.9%), and solar retinopathy (0.2%). In 38.2% of eyes, CNV was idiopathic, and in 5.7% of eyes, multiple causes were coded. One thousand forty-one eyes (44.4%) underwent treatment. The mean age of mean age of patients whose eyes received treatment 13.6 ± 3.5 years compared with 12.4 ± 4.1 years for the untreated group (P < 0.001). In 88.9% of eyes, anti-vascular endothelial growth factor (VEGF) injections were administered, 7.9% of eyes received laser therapy, 0.3% of eyes received photodynamic therapy, and 2.9% of eyes received combination therapy. In the eyes receiving anti-VEGF agents, 68.4% required 3 injections or fewer (P < 0.0001). Eyes undergoing treatment exhibited worse baseline visual acuity (VA) than eyes that did not undergo treatment (0.62 ± 0.50 logarithm of the minimum angle of resolution [logMAR] vs. 0.44 ± 0.50 logMAR; P < 0.0001). Visual acuity in the treatment group improved significantly from 0.62 ± 0.50 logMAR at baseline to 0.39 ± 0.43 logMAR at year 1 (P < 0.0001). Visual acuity in the untreated group improved significantly from 0.44 ± 0.50 logMAR at baseline to 0.34 ± 0.44 logMAR at year 1 (P < 0.001). Treated eyes showed a statistically significant higher odds of exhibiting a 2-line vision improvement or better compared with the untreated group at 12 months regardless of treatment type and after controlling for baseline VA (odds ratio, 2.4; P < 0.0001). CONCLUSIONS: CNV is a rare, sight-threatening condition in children, with the most common causes being idiopathic, inflammatory chorioretinal disease, and myopia. Eyes undergoing treatment tended to be in older patients and showed worse baseline VA compared with eyes that did not undergo treatment. Those that were treated experienced significant improvement in vision that was maintained in the long term.

Management of Type 2 Retinopathy of Prematurity or Less in Infants Aged 45 Weeks Postmenstrual Age or Older.

BACKGROUND AND OBJECTIVE: This study aimed to identify the degree of concordance between fluorescein angiograms (FA) and fundus photographs (FP) in assessing the severity and potential need for treatment in infants 45 weeks or older postmenstrual age (PMA) with type 2 or less retinopathy of prematurity (ROP). PATIENTS AND METHODS: An observational retrospective case series performed at Associated Retinal Consultants, William Beaumont Hospital in Royal Oak, Michigan. All infants born between 2006 and 2016 with stage 1 to 3 ROP that did not meet type 1 ROP criteria (type 2 or less) who received ablative laser therapy during or after age 45 weeks PMA. Pretreatment FP and FA images were randomized and sent to nine expert retina specialist graders to assess severity and inter-grader variability. RESULTS: A total of 10 babies (19 eyes) were enrolled in this study, and 53 FAs and 27 FPs of these 19 eyes were selected to be interpreted by the nine graders. The number of eyes deemed to be abnormal and warranted for treatment was higher with FA, whereas more eyes were deemed "normal" with FP. CONCLUSION: Although still controversial, knowledge of these findings may encourage retina specialists to closely examine infants with mild ROP older than age 45 weeks PMA and consider ablative laser therapy under certain conditions (even if not meeting type 1 Early Treatment for ROP criteria).

Atypical Late-Onset Exudative Retinal Detachment in a Treatment-Naïve Infant With Retinopathy of Prematurity.

A male infant born at 23 weeks gestation with a birthweight of 660 grams presented with retinopathy of prematurity (ROP) that began progressing at 44 weeks. He subsequently developed Zone III, Stage 3, pre-plus disease in both eyes (OU), as well as scattered exudates in the macula, dragged vessels temporally, and an exudative retinal detachment temporally in the left eye after a period of regressing and stable ROP. After bilateral laser photocoagulation, there was regression of the neovascularization, resolution of the exudative detachment, and eventual stabilization of disease OU by 12 months postmenstrual age.

Adult retinopathy of prematurity: treatment implications, long term sequelae, and management.

PURPOSE OF REVIEW: Classically, ROP has been considered a neonatal disease only; however, pediatric ophthalmologists and retinal specialists worldwide are recently facing a new paradigm shift. retinopathy of prematurity (ROP) is now considered a lifelong disease that extends well into adulthood. The purpose of this review is to describe the adult ROP anatomy and discuss the late sequelae and management of this disease. RECENT FINDINGS: Neonatal ROP treatments affect both anterior and posterior segment anatomy. Anterior segment changes secondary to inflammation and posterior ciliary nerve ablation range from acute to chronic pathology, including cataract, secondary glaucoma, and corneal decompensation. Persistent avascular retina can be present in previously treated Type 1 ROP eyes after anti-vascular endothelial growth factor or in 'normal' untreated eyes that did not previously meet Type 1 ROP criteria. Persistent avascular retina is associated with lattice-like changes, retinal tears, and detachments. The location and extent of the ridge, posterior hyaloidal contraction and adhesion, and persistent avascular retina all contribute to a spectrum of findings ranging from reactivation of neovascularization, tractional, rhegmatogenous, or exudative detachments. SUMMARY: Understanding Adult ROP anatomy is critical in identification of retinal pathology and treatment choice. ROP patients require lifelong monitoring.

CLINICAL FEATURES AND OUTCOMES OF INFANTS WITH RETINOPATHY OF PREMATURITY WHO FAIL ANTIVASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY.

PURPOSE: To describe characteristics and outcomes of patients with retinopathy of prematurity who failed intravitreal antivascular endothelial growth factor. METHODS: A retrospective case series of 211 eyes (112 patients) treated with antivascular endothelial growth factor as initial therapy for retinopathy of prematurity at a single academic institution between 2011 and 2019 and an additional 6 eyes (3 patients) referred to us for management of failed antivascular endothelial growth factor. RESULTS: Among the 211 eyes receiving initial treatment at our institution, 17 eyes (11%) failed. Of the 23 total eyes managed by us for failure, 3 eyes (13%) failed after 50-week postmenstrual age. Failure manifested as recurrent plus in 14 eyes (58%), recurrent Stage 3 in 13 eyes (54%) and retinal detachment in 5 eyes (21%). Treatment failures were managed with laser (13 eyes), repeat injection (4 eyes), vitrectomy (2 eyes), or a combination of modalities (4 eyes). Follow-up of ≥6 months was available for 18 of the 23 eyes. The retina was fully attached in 17 eyes, and fixation behavior was present in 10 eyes. CONCLUSION: The most common manifestations of treatment failure were recurrent plus and Stage 3. The failure rate at our institution was 11.0%. A significant proportion of failures occurred after 50-week postmenstrual age. Most failed eyes had favorable anatomical outcomes and over half demonstrated fixation behavior.

Very late-onset reactivation of retinopathy of prematurity post anti-VEGF bevacizumab treatment for type 1 ROP: a case report.

We report the case of 10-year-old girl who developed retinal neovascularization and vitreous hemorrhage 10 years after successful treatment of type 1 retinopathy of prematurity infant with intravitreal bevacizumab without laser ablation therapy.

PERIPHERAL RETINAL ANGIOGRAPHIC FINDINGS IN MACULAR TELANGIECTASIS TYPE 2.

PURPOSE: To evaluate the retinal periphery in patients with idiopathic juxtafoveal telangiectasis or macular telangiectasis Type 2 (MacTel2), using widefield fluorescein angiography. METHODS: Single-center, retrospective, observational case series of 50 eyes of 50 patients with MacTel2 and 50 eyes of 50 age-matched controls. RESULTS: Thirty-seven eyes in the MacTel2 group (74%) showed peripheral capillary nonperfusion or dropout, compared with 37 eyes in the control group (74%, P = 1.0). Morphologically, the MacTel2 group trended toward having a higher proportion of pruning-type capillary dropout (44%) compared with controls (28%), but this was not statistically significant (P = 0.12). Patients with MacTel2 had a higher incidence of microaneurysms compared with controls (MacTel2 56%; controls 42%; P = 0.048), independent of age or systemic risk factors. There was no difference in the incidence of venous-venous shunts (MacTel2 10%; controls 10%; P = 1.0), arteriovenous shunts (MacTel2 14%; controls 18%; P = 0.60), venous tortuosity (MacTel2 60%; controls 66%; P = 0.58), or arterial tortuosity (MacTel2 54%; controls 68%; P = 0.20), which was mild in most cases. CONCLUSION: We note a high incidence of peripheral vascular and retinal findings in both patients with MacTel2 and age-matched controls, using widefield fluorescein angiography. Patients with MacTel2 had significantly more microaneurysms, independent of age or other systemic risk factors.

Reoperation Rates of Patients Undergoing Primary Noncomplex Retinal Detachment Surgery in a Cohort of the IRIS Registry.

PURPOSE: To present the reoperation rates of patients who underwent a primary noncomplex RD repair in a cohort of the American Academy of Ophthalmology IRIS Registry. DESIGN: Retrospective, nonrandomized comparative clinical study. METHODS: This was a retrospective, nonrandomized cohort study of patients who underwent a primary noncomplex RD repair with either a scleral buckle (SB) or vitrectomy with or without scleral buckle (PPV±SB) between 2013 and 2016. The primary outcome was the odds of reoperation within 12 months. RESULTS: Of 24,068 patients, 2,937 patients (12.2%) underwent an SB and 21,131 patients (87.8%) a PPV ± SB. The overall reoperation rate was 12.2% for SB and 11.6% for PPV ± SB. After multivariate adjustment for age and initial RD diagnosis, the PPV ± SB group exhibited a lower odds of reoperation within 12 months compared with SB only (OR 0.84, 95% CI 0.75-0.96, P = .007). However, there was an age interaction. Patients ≤50 years old with PPV ± SB exhibited a higher odds of reoperation (OR 1.46, 95% CI 1.14-1.88, P = .003) compared to SB only. Patients >50 years with PPV ± SB had a lower odds of reoperation (OR 0.73, 95% CI 0.63-0.84, P < .0001). CONCLUSION: The odds of reoperation of PPV ± SB compared with SB only varies depending on the patient's age. Further subset analyses are required to determine if there are clinically relevant differences with respect to RD configuration or other RD repair types (PPV only vs PPV with SB).

Outcomes of Infectious Endophthalmitis in Patients with Systemic Antibiotic Allergies to Penicillins, Cephalosporins, or Vancomycin.

PURPOSE: The mainstay empiric treatments of bacterial endophthalmitis are intravitreal vancomycin and ceftazidime. In the United States, up to 10% of the general population has a reported penicillin (PCN) allergy. Despite low cross-reactivity between PCN and later-generation cephalosporins, some providers alter the intravitreal antibiotic choice for endophthalmitis because of concern for allergic reactions. We evaluated the management strategies of infectious endophthalmitis in the setting of self-reported systemic antibiotic allergies and the association with adverse reactions after standard intravitreal antibiotic administration. DESIGN: Single-center, retrospective cohort study. PARTICIPANTS: All patients with endophthalmitis between 2005 and 2019 and documented PCN, PCN-analog, cephalosporin, or vancomycin allergy who received intravitreal antibiotics on the basis of International Classification of Diseases 9th and 10th Revisions, and Current Procedural Terminology codes. METHODS: Retrospective chart review. MAIN OUTCOME MEASURES: Any allergic reaction after intravitreal injection, additional surgical interventions required for treatment, and visual function at last recorded visit. RESULTS: Of the 65 patients included in this cohort, the most common causes of endophthalmitis were postcataract extraction surgery (n = 23, 35.4%) and postintravitreal injection (n = 11, 16.9%). All patients (65/65) received intravitreal vancomycin, and 81.5% (53/65) received intravitreal ceftazidime. Of the 53 patients who received intravitreal ceftazidime, 46 (86.8%) had allergies to PCNs alone, 5 (9.4%) had a cephalosporin allergy alone, and 2 (3.8%) had reported allergies to both PCN and cephalosporin antibiotics. Two patients (3.1%) with a documented vancomycin allergy received intravitreal vancomycin without complication. No patients exhibited any systemic or local allergic reactions or complications after intravitreal injection. CONCLUSIONS: There were no documented allergic reactions in this cohort of patients with systemic antibiotic allergies who were treated for infectious endophthalmitis. Our findings are consistent with previous reports of a low allergic cross-reactivity between PCN and later-generation cephalosporins. Ophthalmologists should use evidence-based practices and a careful informed consent process when choosing intravitreal antibiotics for patients with specific antibiotic allergies. In the routine patient with suspected bacterial endophthalmitis, PCN allergy may not be an absolute contraindication to intravitreal cephalosporin use.

Visual and Anatomic Outcomes of Premacular Hemorrhage in Non-Accidental Trauma Infants Managed With Observation or Vitrectomy.

BACKGROUND AND OBJECTIVE: The management of premacular hemorrhage secondary to non-accidental trauma (NAT) is unclear. The authors describe the outcomes of NAT infants referred for surgical evaluation of premacular hemorrhage. PATIENTS AND METHODS: Retrospective institutional review board-approved case series between 2000 and 2019 of vision-threatening premacular hemorrhage (sub-hyaloid or sub-internal limiting membrane hemorrhage without vitreous hemorrhage) in NAT infants. Time to hemorrhage resolution, vision, and comorbidities were collected. RESULTS: Thirty-six patients (62 eyes) with mean age of 5.4 months (range: 2-10 months) were included. Nine eyes (14.5%) underwent vitrectomy. Median time to hemorrhage resolution by observation was 75 days (interquartile range [IQR]: 60-120 days), and time to vitrectomy was 54.5 days (IQR: 47.8-58.5 days). Eight eyes (12.9%) had amblyopia, which was not significantly different between groups. Despite hemorrhage clearance, a higher proportion of eyes in the vitrectomy group had pigmentary changes (P = .04) and strabismus (P = .002) at follow-up. CONCLUSIONS: Most cases of NAT-related premacular hemorrhage resolve within 3 months without surgical intervention. Comorbidities may limit visual prognosis.

Reactivation of Retinopathy of Prematurity in Adults and Adolescents.

PURPOSE: To review the clinical features, treatment outcomes, and prevalence within our clinic population of adolescents and adults with previously regressed retinopathy of prematurity (ROP) who demonstrate late-onset exudation and vasoproliferative changes. DESIGN: Retrospective review of consecutive patients at a single center. PARTICIPANTS: Five patients (5 eyes) with a history of ROP who showed new exudates or worsening fibrovascular proliferation diagnosed after 10 years of age. METHODS: Patients were identified by a computerized search of the Emory Eye Center billing records. Data extracted from charts included baseline ROP information, visual acuity and other examination findings, imaging, and treatments. MAIN OUTCOME MEASURES: Status of exudation and vasoproliferation. RESULTS: Among 138 patients older than 10 years with ROP seen at our tertiary referral center from 2000 through 2018, 5 (3.6%) demonstrated late-onset exudation or vasoproliferation. Three patients were female and 3 underwent ROP treatment as neonates. Mean age at onset of late reactivation was 25.6 years (range, 13-43 years). Previous treatments for neonatal ROP included peripheral laser ablation (n = 3), scleral buckle (n = 2), pars plicata vitrectomy (n = 2), and no treatment (n = 2). Management strategies for late reactivation included observation (n = 1), intravitreal anti-vascular endothelial growth factor agents (n = 4), vitrectomy (n = 2), and cryotherapy (n = 1). With mean follow-up of 4.8 years (range, 1-7 years), outcomes were resolution of exudation or proliferation with return to baseline vision (n = 2), stable mild exudation (n = 1), and progressive vasoproliferation with traction leading to phthisis (n = 2). CONCLUSIONS: Late-onset exudation and fibrovascular proliferation in adolescents and adults with ROP can occur rarely with previously regressed ROP. Two of 5 patients were refractory to all treatments and demonstrated phthisis bulbi. One patient showed reactivation in the form of a reactive retinal astrocytic tumor. Our findings highlight the importance continued monitoring with regular fundus examination in adolescents and adults with regressed ROP.
