TOWARD AN IMAGING-CENTRIC DEFINITION OF NONPARANEOPLASTIC AUTOIMMUNE RETINOPATHY.

PURPOSE: To explore characteristic imaging features of nonparaneoplastic autoimmune retinopathy (npAIR) to augment diagnostic criteria. METHODS: This is a retrospective cohort study of patients with npAIR evaluated at the Emory Eye Center between 2013 and 2019. Multimodal fundus images were evaluated to characterize the evolution of the disease. RESULTS: Twenty-one eyes of 12 patients were classified as having npAIR. Five patients (42%) were female, with median (range) age of 59 years (45-85 years). Median baseline visual acuity was 20/30 (20/20 to hand motions). Disease was asymmetric in 11 patients (92%). Common imaging findings included absence of bone spicules (86% of affected eyes), presence of attenuated vessels (86%), and speckled hypoautofluorescence in perimacular and perivenular regions. Three eyes were noted to present early with subtle splotchy fundus autofluorescence abnormality, ultimately developing characteristic speckled perimacular hypoautofluorescence. On optical coherence tomography, 18 eyes (86%) had loss of outer retinal bands with relative foveal sparing and a tapered transition zone. CONCLUSION: Many eyes with npAIR exhibit a subacute, asymmetric, generalized photoreceptor degeneration featuring outer retinal atrophy with relative foveal sparing, retinal vascular attenuation, absence of bone spicules, and speckled hypoautofluorescence often in a perimacular and perivenular distribution. Findings of this study augment diagnostic criteria to improve specificity and accessibility of testing for npAIR.

Correlation of gene expression with magnetic resonance imaging features of retinoblastoma: a multi-center radiogenomics validation study.

OBJECTIVES: To validate associations between MRI features and gene expression profiles in retinoblastoma, thereby evaluating the repeatability of radiogenomics in retinoblastoma. METHODS: In this retrospective multicenter cohort study, retinoblastoma patients with gene expression data and MRI were included. MRI features (scored blinded for clinical data) and matched genome-wide gene expression data were used to perform radiogenomic analysis. Expression data from each center were first separately processed and analyzed. The end product normalized expression values from different sites were subsequently merged by their Z-score to permit cross-sites validation analysis. The MRI features were non-parametrically correlated with expression of photoreceptorness (radiogenomic analysis), a gene expression signature informing on disease progression. Outcomes were compared to outcomes in a previous described cohort. RESULTS: Thirty-six retinoblastoma patients were included, 15 were female (42%), and mean age was 24 (SD 18) months. Similar to the prior evaluation, this validation study showed that low photoreceptorness gene expression was associated with advanced stage imaging features. Validated imaging features associated with low photoreceptorness were multifocality, a tumor encompassing the entire retina or entire globe, and a diffuse growth pattern (all p < 0.05). There were a number of radiogenomic associations that were also not validated. CONCLUSIONS: A part of the radiogenomic associations could not be validated, underlining the importance of validation studies. Nevertheless, cross-center validation of imaging features associated with photoreceptorness gene expression highlighted the capability radiogenomics to non-invasively inform on molecular subtypes in retinoblastoma. CLINICAL RELEVANCE STATEMENT: Radiogenomics may serve as a surrogate for molecular subtyping based on histopathology material in an era of eye-sparing retinoblastoma treatment strategies. KEY POINTS: • Since retinoblastoma is increasingly treated using eye-sparing methods, MRI features informing on molecular subtypes that do not rely on histopathology material are important. • A part of the associations between retinoblastoma MRI features and gene expression profiles (radiogenomics) were validated. • Radiogenomics could be a non-invasive technique providing information on the molecular make-up of retinoblastoma.

IODINE-125 PLAQUE BRACHYTHERAPY FOR DIFFUSE CHOROIDAL HEMANGIOMA.

PURPOSE: To report 6 cases of diffuse choroidal hemangioma in children treated with iodine-125 plaque brachytherapy at a single tertiary care center. METHODS: Retrospective case series. RESULTS: Six pediatric patients diagnosed with diffuse choroidal hemangioma were included in the study. Preplaque visual acuity ranged from 20/150 to no light perception. All patients had extensive serous retinal detachment at presentation. An iodine-125 radioactive plaque was placed on the affected eye to administer a dose of 34.2-42.1 Gy to the tumor apex over a median of 4 days. Tumor regression and subretinal fluid resolution were observed in all eyes within 17 months of treatment. Visual acuity improved in two patients. Radiation-induced cataract and subretinal fibrosis were documented in one case, and one patient developed radiation retinopathy. No patients developed neovascular glaucoma within the follow-up time of 12-65 months. CONCLUSION: Iodine-125 plaque radiotherapy is an effective option for diffuse choroidal hemangioma, although there is a risk for radiation-induced complications.

Cancer awareness in Australian adolescents.

BACKGROUND: Over one-third of cancer cases are attributable to modifiable risk factors. Because health-related behaviors are often established at adolescence, it is important that adolescents understand the risks and lifestyle decisions that may reduce their chances of developing cancer. This study aims to identify the levels of cancer awareness of adolescents in Australia. METHODS: Paper questionnaires were used to collect information about baseline levels of cancer awareness. These questionnaires included socio-demographic questions and the Cancer Awareness Measure (CAM) with slight modifications to ensure their suitability for the Australian adolescent population. Students aged 11 to 19 years were recruited from 13 Australian high schools between 2016 and 2019. RESULTS: A total of 766 adolescents (58% female, mean age = 14.5 years) completed the questionnaires. Adolescents' cancer awareness was low. Adolescents who knew someone with cancer recognized significantly more cancer risk factors and cancer warning signs than those who did not know someone with cancer (t (756) = 2.35, p = .019; t (747) = 5.57, p = .001). Those from high Index of Community Socio-Educational Advantage (ICSEA) schools significantly recognized more cancer risk factors than those from low ICSEA schools (t (764) = 2.42, p = .016). Females recognized significantly more warning signs than males (t (583) = 3.11, p = .002) and students from senior high school grades recognized more warning signs than those from junior grades (t (754) = 2.24, p = .02). Most adolescents (78%) were aware of skin cancer as one of the most common cancers in Australia, however half or less were aware of other common cancers. Although most adolescents would seek medical help in the presence of possible cancer symptoms as soon as possible, approximately 20% of them would not see a doctor promptly. Emotional barriers were the most common reasons to delay seeing a doctor (56%), for example "being worried about hearing bad news" (27%). CONCLUSIONS: Australian adolescents show poor awareness of cancer risk factors and cancer warning signs. A number of demographic and experience factors were found to be related to lower cancer awareness. Education is essential to raise cancer awareness, promote healthy lifestyles from adolescence and avoid a preventable cancer diagnosis.

Transversus abdominis plane blocks in laparoscopic inguinal hernia repair: a review.

INTRODUCTION: Throughout its history, there have been significant advances in pain control of inguinal hernia repairs. One of the most recent developments is locoregional pain blocks. There is a multitude of literature available on laparoscopic inguinal hernia repair and transversus abdominis plane (TAP) blocks. OBJECTIVES: This paper seeks to provide a thorough and systematic literature review on the role of TAP blocks in laparoscopic inguinal hernia repairs. METHODS: PubMed and Google Scholar were searched for relevant literature using predetermined medical subject heading (MeSH) terms: "(TAP block)" AND "(Laparoscopic inguinal hernia repair)". RESULTS: A total of 166 publications were identified, from which 18 publications were included in the final review after eligibility criteria were applied. CONCLUSION: The majority of studies conclude that TAP blocks performed in the setting of laparoscopic inguinal hernia repair improve post-operative pain and mobility, decrease opiate analgesic usage, and are superior in pain control compared to other modalities of regional anesthesia. Thus, to improve post-operative outcomes and patient satisfaction, TAP blocks should be heavily considered for routine use in surgical practice for laparoscopic inguinal hernia repair.

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.

MRI Features for Identifying MYCN-amplified RB1 Wild-type Retinoblastoma.

Background MYCN-amplified RB1 wild-type (MYCNARB1+/+) retinoblastoma is a rare but clinically important subtype of retinoblastoma due to its aggressive character and relative resistance to typical therapeutic approaches. Because biopsy is not indicated in retinoblastoma, specific MRI features might be valuable to identify children with this genetic subtype. Purpose To define the MRI phenotype of MYCNARB1+/+ retinoblastoma and evaluate the ability of qualitative MRI features to help identify this specific genetic subtype. Materials and Methods In this retrospective, multicenter, case-control study, MRI scans in children with MYCNARB1+/+ retinoblastoma and age-matched children with RB1-/- subtype retinoblastoma were included (case-control ratio, 1:4; scans acquired from June 2001 to February 2021; scans collected from May 2018 to October 2021). Patients with histopathologically confirmed unilateral retinoblastoma, genetic testing (RB1/MYCN status), and MRI scans were included. Associations between radiologist-scored imaging features and diagnosis were assessed with the Fisher exact test or Fisher-Freeman-Halton test, and Bonferroni-corrected P values were calculated. Results A total of 110 patients from 10 retinoblastoma referral centers were included: 22 children with MYCNARB1+/+ retinoblastoma and 88 control children with RB1-/- retinoblastoma. Children in the MYCNARB1+/+ group had a median age of 7.0 months (IQR, 5.0-9.0 months) (13 boys), while children in the RB1-/- group had a median age of 9.0 months (IQR, 4.6-13.4 months) (46 boys). MYCNARB1+/+ retinoblastomas were typically peripherally located (in 10 of 17 children; specificity, 97%; P < .001) and exhibited plaque or pleomorphic shape (in 20 of 22 children; specificity, 51%; P = .011) with irregular margins (in 16 of 22 children; specificity, 70%; P = .008) and extensive retina folding with vitreous enclosure (specificity, 94%; P < .001). MYCNARB1+/+ retinoblastomas showed peritumoral hemorrhage (in 17 of 21 children; specificity, 88%; P < .001), subretinal hemorrhage with a fluid-fluid level (in eight of 22 children; specificity, 95%; P = .005), and strong anterior chamber enhancement (in 13 of 21 children; specificity, 80%; P = .008). Conclusion MYCNARB1+/+ retinoblastomas show distinct MRI features that could enable early identification of these tumors. This may improve patient selection for tailored treatment in the future. © RSNA, 2023 Supplemental material is available for this article. See also the editorial by Rollins in this issue.

A Multicenter Analysis of Nucleic Acid Quantification Using Aqueous Humor Liquid Biopsy in Retinoblastoma: Implications for Clinical Testing.

Purpose: Retinoblastoma (RB) is most often diagnosed with clinical features and not diagnosed with tumor biopsy. This study describes tumor-derived analyte concentrations from aqueous humor (AH) liquid biopsy and its use in clinical assays. Design: Case series study. Participants: Sixty-two RB eyes from 55 children and 14 control eyes from 12 children from 4 medical centers. Methods: This study included 128 RB AH samples including: diagnostic (DX) samples, samples from eyes undergoing treatment (TX), samples after completing treatment (END), and during bevacizumab injection for radiation therapy after completing RB treatment (BEV). Fourteen-control AH were analyzed for unprocessed analytes (double-stranded DNA [dsDNA], single-stranded DNA [ssDNA], micro-RNA [miRNA], RNA, and protein) with Qubit fluorescence assays. Double-stranded DNA from 2 RB AH samples underwent low-pass whole-genome sequencing to detect somatic copy number alterations. Logistic regression was used to predict disease burden given analyte concentrations. Main Outcome Measures: Unprocessed analyte (dsDNA, ssDNA, miRNA, RNA and protein) concentrations. Results: Results revealed dsDNA, ssDNA, miRNA, and proteins, but not RNA, were quantifiable in most samples (up to 98%) with Qubit fluorescence assays. Median dsDNA concentration was significantly higher in DX (3.08 ng/µl) compared to TX (0.18 ng/µl; P < 0.0001) at an order of 17 times greater and 20 times greater than END samples (0.15 ng/µl; P = 0.001). Using logistic regression, nucleic acid concentrations were useful in predicting higher versus lower RB disease burden. Retinoblastoma somatic copy number alterations were identified in a TX, but not in a BEV sample, indicating the correlation with RB activity. Conclusions: Aqueous humor liquid biopsy in RB is a high-yield source of dsDNA, ssDNA, miRNA, and protein. Diagnostic samples are most useful for RB 1 gene mutational analyses. Genomic analysis may be more informative of tumor activity status than quantification alone and can be performed even with smaller analyte concentrations obtained from TX samples.

A Novel Approach to Subretinal Fluid Drainage in Coats'-Related Exudative Retinal Detachment.

Laser is effective at treating exudative retinal detachment (ERD) in Coats' disease. However, with severe ERD, the retina may be in contact with the lens. In such cases, laser can result in cataract formation. This case report of two patients treated at an academic medical center for Coats'-related ERD describes a technique of minimally invasive subretinal fluid drainage to create space between the lens and retina to avoid cataract. Transconjunctival unguarded needle drainage allowed for complete treatment of telangiectatic vessels and resulted in favorable anatomical outcomes in the patients. Transconjunctival unguarded needle drainage is a useful technique for treating severe, Coats'-related ERD, when a bullously detached retina is in contact with the lens.

Low- and Very Low-Dose Bevacizumab for Retinopathy of Prematurity: Reactivations, Additional Treatments, and 12-Month Outcomes.

PURPOSE: Low-dose and very low-dose intravitreal bevacizumab (IVB) have been reported to be successful in short-term treatment of type 1 retinopathy of prematurity (ROP), down to an initial dose of 0.004 mg. We now report 12-month outcomes for these infants. DESIGN: Masked, multicenter, dose de-escalation study. PARTICIPANTS: One hundred twenty prematurely born infants with type 1 ROP. METHODS: A cohort of 120 infants with type 1 ROP in at least 1 eye from 2 sequential dose de-escalation studies of low-dose IVB (0.25 mg, 0.125 mg, 0.063 mg, and 0.031 mg) or very low-dose IVB (0.016 mg, 0.008 mg, 0.004 mg, and 0.002 mg) to the study eye; the fellow eye (if also type 1) received 1 dose level higher of IVB. After primary success or failure at 4 weeks, clinical management was at investigator discretion, including all additional treatment. MAIN OUTCOME MEASURES: Reactivation of severe ROP by 6 months corrected age, additional treatments, retinal and other ocular structural outcomes, and refractive error at 12 months corrected age. RESULTS: Sixty-two of 113 study eyes (55%) and 55 of 98 fellow eyes (56%) received additional treatment. Of the study eyes, 31 (27%) received additional ROP treatment, and 31 (27%) received prophylactic laser therapy for persistent avascular retina. No trend toward a higher risk of additional ROP treatment related to initial IVB doses was found. However, time to reactivation among study eyes was shorter in eyes that received very low-dose IVB (mean, 76.4 days) than in those that received low-dose IVB (mean, 85.7 days). At 12 months, poor retinal outcomes and anterior segment abnormalities both were uncommon (3% and 5%, respectively), optic atrophy was noted in 10%, median refraction was mildly myopic (-0.31 diopter), and strabismus was present in 29% of infants. CONCLUSIONS: Retinal structural outcomes were very good after low- and very low-dose IVB as initial treatment for type 1 ROP, although many eyes received additional treatment. The rate of reactivation of severe ROP was not associated with dose; however, a post hoc data-driven analysis suggested that reactivation was sooner with very low doses.

The Prevalence of Retinal Disease and Associated CNS Disease in Young Patients with Incontinentia Pigmenti.

PURPOSE: To evaluate the prevalence of retinal disease on fluorescein angiography (FA) in patients with incontinentia pigmenti (IP) and to compare the severity of retinal disease in those with and without known central nervous system (CNS) disease. DESIGN: Multi-institutional consecutive retrospective case series. SUBJECTS: New patients with a diagnosis of IP were seen at the Casey Eye Institute at the Oregon Health and Science University (OHSU), Moran Eye Center, University of Utah, or Bascom Palmer Eye Institute, University of Miami from December 2011 to September 2018. METHODS: Detailed ophthalmoscopic examination and FA were recommended for all new patients and performed on every patient who had parental consent. Ophthalmoscopic findings and FA images were graded for severity by 2 masked graders on a 3-point scale: 0 = no disease, 1 = vascular abnormalities without leakage, 2 = leakage or neovascularization, and 3 = retinal detachment. The presence of known CNS disease was documented. Additional cases were obtained from a pediatric retina listserv for examples of phenotypic variation. MAIN OUTCOME MEASURES: The proportion of eyes noted to have disease on ophthalmoscopy compared with FA and the severity of retinal disease in those with and without known CNS disease. RESULTS: Retinal pathology was detected in 18 of 35 patients (51%) by indirect ophthalmoscopy and 26 of 35 patients (74%) by FA (P = 0.048) in a predominantly pediatric population (median age, 9 months). Ten patients (29%) had known CNS disease at the time of the eye examination. A Wilcoxon rank-sum test indicated that the retinal severity scores for patients with CNS disease (median, 2) were significantly higher than the retinal severity scores for patients without CNS disease (median, 1), z = -2.12, P = 0.034. CONCLUSIONS: Retinal disease is present in the majority of patients with IP, and ophthalmoscopic examination is less sensitive than FA for detection of disease. There may be a correlation between the severity of retinal and CNS disease.

Unilateral Xanthocoria and Retinal Vascular Anomalies in a 3-Year-Old Boy: Retinoblastoma or Coats Disease?

The authors describe a challenging case of unilateral retinoblastoma in a patient referred for xanthocoria. A 3-year-old boy was referred for unilateral xanthocoria and disordered retinal vasculature, suggestive of Coats disease. Further investigation revealed diffuse subretinal tumor seeding and areas of calcification, consistent with retinoblastoma. Enucleation was performed and histopathology confirmed exophytic retinoblastoma. This case highlights that xanthocoria, although often encountered in patients with Coats disease, can sometimes be associated with retinoblastoma. As such, retinoblastoma should be considered in the differential diagnosis for children with both leukocoria and xanthocoria. [J Pediatr Ophthalmol Strabismus. 2022;59(X):e32-e34.].

Surgical Outcomes of Progressive Retinoschisis-Related Retinal Detachments: A 17-Year Survey From a Large Academic Center.

BACKGROUND AND OBJECTIVE: To provide an overview of progressive retinoschisis-related retinal detachment (RSRD) management at a tertiary referral center. MATERIALS AND METHODS: Single-institution retrospective case series from January 1, 2003, to May 1, 2020. RESULTS: Progressive RSRD occurred in 0.9% of patients with retinoschisis. Mean (range) age at time of surgery was 58.7 years (40.0 to 74.0). Ten eyes were initially treated with scleral buckle, three eyes with vitrectomy, and three eyes with combined scleral buckle and vitrectomy. Overall reattachment rate was 100.0%; single-surgery success was 56.2%. Proliferative vitreoretinopathy developed in 10.0% of scleral buckles, 33.3% of vitrectomies, and 33.3% of combined surgeries. CONCLUSIONS: Progressive RSRD is rare and poses surgical management challenges. Final retinal attachment can be achieved successfully but often requires secondary and staged surgeries. Localization of outer retinal breaks may help guide surgical management. Further research-such as a large-scale, prospective, multicenter, randomized trial-would be needed to determine the optimal surgical technique.

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.

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.

Referable Macular Hemorrhage-A Clinically Meaningful Screening Target in Newborn Infants. Position Statement of the Association of Pediatric Retina Surgeons.

Universal newborn eye screening facilitates early diagnosis of ocular abnormalities and mitigates vision loss. "Referral warranted" eye disease is present at birth in about 5.5% of term infants, with "macular hemorrhage impinging on the fovea" representing about 50% of referral warranted disease. The Association of Pediatric Retina Surgeons held a symposium on February 9, 2021 that culminated in a position statement on "referable macular hemorrhage" (RMH) in newborn infants. RMH is meaningful in that in can cause amblyopia through deprivation, can be readily captured with wide-angle photography in a safe and efficient manner, and may lead to early intervention with mitigation of vision loss.

PROLIFERATIVE RETINOPATHY IN A 13-YEAR-OLD WITH ADAMS-OLIVER SYNDROME.

PURPOSE: Adams-Oliver syndrome is a rare, inherited disorder of embryologic development that affects multiple systems. Ocular manifestations have been poorly characterized because of the low prevalence and high mortality of the disease when it is associated with internal organ and/or ophthalmic manifestations. We present a case of Adams-Oliver syndrome in a 13-year-old patient whose multimodal retinal imaging findings helped direct management. METHODS: Single patient case report reviewing medical records and imaging. RESULTS: Visual acuity upon presentation was 20/40 in each eye. Ultra-widefield fluorescein angiography revealed peripheral nonperfusion with terminal vascular bulbs, and leakage from a temporal fibrovascular complex in the left eye. Fundus autofluorescence imaging showed hyperautofluorescence associated with optic disc drusen and the fibrovascular complex. Treatment with targeted laser photocoagulation was associated with regression of the neovascularization. CONCLUSION: Retinal manifestations of Adams-Oliver syndrome as observed with ultra-widefield fundus imaging may resemble those of familial exudative vitreoretinopathy and retinopathy of prematurity. Treatment of avascular retina with panretinal photocoagulation can be considered.

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.

Complications of retinopathy of prematurity treatment.

PURPOSE OF REVIEW: The purpose of this review is to summarize complications of treatment for retinopathy of prematurity (ROP) and to compare complications of laser and intravitreal antivascular endothelial growth factor (VEGF) injections. RECENT FINDINGS: Poor structural outcomes and myopia are more common with laser for severe ROP than with anti-VEGF. Clinical trial data show unfavourable outcomes in 9.1-9.5% of laser treated, and 1.4-3.6% of anti-VEGF treated eyes. Additional randomized trial data show risk for very high myopia (≥-8.00D) to be 3.8 and 51.4% for zone I eyes treated with bevacizumab and laser, respectively. However, anti-VEGF may be complicated by late recurrence and is more likely to require retreatment than laser. Laser often necessitates general anaesthesia with its attendant risks, including worse short-term respiratory outcomes. Neurodevelopmental complications have been reported with anti-VEGF, but existing studies are subject to bias. SUMMARY: Treatment complications are substantially different for the two modalities in common use today. In more severe cases, risk of poor structural outcome and myopia favour treatment with anti-VEGF. In less severe ROP, risk of recurrence and the need for additional treatments may favour laser. Additional data are needed to establish comparative risks of neurodevelopmental complications.
