Spontaneous Resolution of a Combined Hamartoma in a One-Year-Old Child.

The combined hamartoma of the retina and the retinal pigment epithelium (CHR-RPE) is a rare but histologically benign tumor of which no clear consensus exists regarding its appropriate management. Most commonly CHR-RPE presents unilaterally in children as an elevated, pigmented lesion associated with vascular tortuosity and an epiretinal membrane (ERM). Patients may have decreased visual acuity (VA) in the affected eye, notably if the overlying ERM extends into the macula. For this reason, surgical intervention in the form of ERM removal has been pursued with notable success. Still, those who pursue observation cite the interwoven nature of the overlying glial membrane within the dysplastic retina, complicating surgery and accounting for variability in post-operative VA success. Given the rarity of the tumor coupled with the scarcity of data on its natural evolution, clinicians who pursue observation cannot know for sure whether withholding surgical management is predisposing their patients to worse visual outcomes as compared to those patients who undergo ERM peel as first-line therapy. This case report will discuss an infant with clinically diagnosed CHR-RPE whose lesion showed significant regression after 6 months of observation. This success story should cause Ophthalmologists to reconsider the management options at their disposal when faced with a case of CHR-RPE, and to call for further research to better define the risks of observation over surgical intervention.

Bilateral Combined Rhegmatogenous and Tractional Retinal Detachments Due to Persistent High-Titer Syphilis.

A 23-year-old man developed bilateral rhegmatogenous retinal detachments secondary to high-titer ocular syphilis. The patient's titer increased four-fold after completing a 14-day course of intravenous penicillin (IVP). He underwent bilateral pars plana vitrectomy with silicone oil fill in both eyes. In this article, the authors propose an updated treatment method for patients with advanced ocular syphilis that includes oral doxycycline for 30 days following 14 days of IVP to optimally minimize the patient's infectious burden. Following surgery and this new treatment regime, this patient's best-corrected visual acuity 10 weeks postoperatively measured 20/50 in the right eye and 20/30 in the left eye. This case highlights a rare but devastating complication of ocular syphilis. We suggest the addition of oral doxycycline to IVP for patients with syphilis titers ≥ 1:256, HIV co-infection, and presence of posterior retinitis.

Choroidal measurements in decision making for retinopathy of prematurity: a decision tree analysis.

BACKGROUND: To compare the choroidal thickness and vascular profile of premature infants with ROP (retinopathy of prematurity) using a handheld SD-OCT device. METHODS: We performed horizontal SD-OCT scans through the fovea in 115 eyes of 66 premature infants. Premature infants included 2 groups [infants with ROP requiring treatment (as treatment group) vs. infants without ROP or with ROP not- requiring treatment (as no-treatment group)] Choroidal thicknesses (CT) were measured at 5 points, including the fovea, 250 µm, and 500 µm mm nasal and temporal to the fovea. The choroidal vascularity index (CVI) and choroidal stromal index (CSI) were also calculated. The classification and regression tree (CRT) algorithm was used to predict the need for treatment based on all OCT characteristics. RESULTS: Mean CT was higher in 500 µm nasal to the fovea compared to temporal CT (275.8 ± 64.8 and 257.1 ± 57.07, P value < 0.03). No statistically significant difference was found regarding CVI, corrected CVI, and temporal and nasal CT in the treatment group versus the no-treatment group. The foveal CT was significantly lower in ROP patients with the plus disease compared to not-plus ROP (P value = 0.03. ANOVA, Bonferroni posthoc test). CT was not significantly different between plus and pre-plus patients (P-value = 0.9, ANOVA, Bonferroni posthoc test). No significant relationship was found between the stage of ROP and choroidal thickness (P value > 0.05, GEE). The decision tree analysis showed that in infants with ROP, the most important predictor for the need for treatment is CSI. CONCLUSION: This study delineated the possible effectiveness of choroidal measurements as an additive to decision-making for ROP. We also demonstrated that choroidal involution is associated with the presence of plus disease, not with the stage of ROP. We demonstrated that choroidal measurements are very sensitive but not specific tools for assessing the need for treatment in ROP patients.

Potential application of foveal structural measurements in treatment decision for retinopathy of prematurity: an OCT-based study.

PURPOSE: To investigate foveal changes in infants with ROP not requiring treatment(nROP) and ROP infants needing treatment (tROP) using a handheld SD-OCT device. METHOD: We performed horizontal SD-OCT scans through the fovea in 156 eyes of 81 infants diagnosed with ROP. Foveal immaturity indices including the presence of inner retinal layers (IRL), absence of foveal outer nuclear layers widening (ONL) and attenuation of hyperreflective outer segment layers (OS), presence and type of cystoid macular edema (CME), epiretinal membrane (ERM), foveal pit depth (FPD), foveal pit width (FPW) and central foveal thickness (CFT) were calculated. The multivariate logistic regression model was used to predict the need for treatment based on OCT measurements. RESULTS: The shape of the foveolar pit was not significantly different among tROP and nROP groups (P-value = 0.287, Chi-square test). IRL extrusion was incomplete in both tROP and nROP groups (P-value = 0.0.41, Chi-square test). Nevertheless, the presence of thicker IRL was more frequent in the nROP group in comparison with the tROP group (100% vs.64.8%, P-value = 0.001). CME was observed in 29% of eyes in the tROP group and 40% of eyes in the nROP group; however, this difference was not statistically significant (P-value = 0.32, Chi-square test). ERM was detected in 15 (75%) and 84 (65.6%) eyes in the nROP and tROP groups, respectively (P-value = 0.39, Chi-square test). Multivariate logistic regression analyses showed that the need for treatment was significantly associated with gestational age (GA), CFT and FPD (P-values 0.001 and 0.002 respectively). CONCLUSIONS: This study demonstrated GA, foveal pit depth and the central foveal thickness could accurately predict the need for treatment with sensitivity, specificity, and diagnostic accuracy of 97%, 65% and 91.7% respectively.

The impact of the COVID-19 lockdown on retinopathy of prematurity screening and management in the United States: a multicenter study.

PURPOSE: To study the effect of the pandemic-related lockdown (physical distance measures and movement restrictions) on the characteristics and management of retinopathy of prematurity (ROP). METHODS: In this controlled, multicenter cohort study, the medical records of patients born prematurely and screened for ROP in the neonatal intensive care unit during four time periods were reviewed retrospectively: (1) November 1, 2018, to March 15, 2019; (2) March 16, 2019, to August 2, 2019 (lockdown control period); (3) November 1, 2019, to March 15, 2020; and (4) March 16, 2020-August 2, 2020. RESULTS: A total of 1,645 patients met inclusion criteria. Among the 1,633 patients with complete data, mean gestational age (GA) at birth was 28.2, 28.4, 28.0, and 28.3 weeks across time periods 1 to 4, respectively (P = 0.16). The mean birth weight of all patients was 1079.1 ± 378.60 g, with no significant variation across time periods (P = 0.08). There were fewer patients screened during the lockdown period (n = 411) compared with the period immediately before (n = 491) and the same period in the prior year (n = 533). Significantly more patients were screened using indirect ophthalmoscopy, compared to digital imaging (telemedicine), during the lockdown (P < 0.01). There were 11.7%, 7.7%, 9.0%, and 8.8% of patients requiring treatment in each time period, respectively (P = 0.42), with a median postmenstrual age at initial treatment of 37.2, 36.45, 37.1, and 36.3 weeks, respectively (P = 0.32). CONCLUSIONS: We recorded a decrease in the number of infants meeting criteria for ROP screening during the lockdown. The GA at birth and birth weight did not differ. Significantly more infants were screened with indirect ophthalmoscopy, compared to digital imaging, during the lockdown.

Retinopathy of Prematurity in the 21st Century and the Complex Impact of Supplemental Oxygen.

Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. Not only do the epidemiologic determinants and distributions of patients with ROP vary worldwide, but clinical differences have also been described. The Third Edition of the International Classification of ROP (ICROP3) acknowledges that aggressive ROP (AROP) can occur in larger preterm infants and involve areas of the more anterior retina, particularly in low-resource settings with unmonitored oxygen supplementation. As sub-specialty training programs are underway to address an epidemic of ROP in sub-Saharan Africa, recognizing characteristic retinal pathology in preterm infants exposed to unmonitored supplemental oxygen is important to proper diagnosis and treatment. This paper describes specific features associated with various ROP presentations: oxygen-induced retinopathy in animal models, traditional ROP seen in high-income countries with modern oxygen management, and ROP related to excessive oxygen supplementation in low- and middle-income countries: oxygen-associated ROP (OA-ROP).

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.

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.

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.

Retinopathy of Prematurity Screening Examination and Changes in Vital Signs.

BACKGROUND AND OBJECTIVE: Dilation and examination during retinopathy of prematurity (ROP) screening can cause systemic complications and even life-threatening adverse events (AEs). The main objective of this study is to assess the prevalence and significance of AEs and changes in vital signs during ROP screenings, and to correlate birth weight, gestational age, and length of exam as possible predictors of these changes. PATIENTS AND METHODS: This is a prospective, observational study that includes 1,360 screening exams from 680 premature infants in two neonatal intensive care units. Systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, and oxygen saturation were monitored from the time that dilating drops were administered until 4 hours after the examination was completed. Any clinical deterioration or complication was documented. RESULTS: Of 1,360 infant screening exams, 153 (11%) screening exams resulted in at least one change in vital sign that alerted the monitor. There was one serious AE requiring bag valve mask resuscitation 30 minutes after dilating drops were placed. Gestational age, birth weight, and length of ROP exam were not significant predictors of AEs. There were statistically significant changes when comparing pre- and post-vital signs following dilation and funduscopy exam. CONCLUSIONS: Although ROP screening exams are essential for at-risk neonates, mydriatic drops and retinal exams can result in changes to vital signs and AEs. It is important to closely monitor neonates during these examinations. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:458-463.].

Self-Induced Bilateral Retinal Detachments and Traumatic Cataracts in a Patient With Bohring-Opitz Syndrome.

A 9-year-old female with a history of Bohring-Opitz syndrome (BOS), Down syndrome, and autism initially presented with bilateral cataracts and a total retinal detachment in her left eye secondary to chronic self-injurious behavior. The authors report the first case of self-induced retinal detachment and traumatic cataracts in a patient with BOS. For patients who present with self-injurious behavior, the authors advocate for behavioral modifications at home, including the use of "no-no's," supplemental medication if necessary, and behavioral therapy to reduce the risk of self-induced visual injury. The authors also suggest the use of 25-gauge vitrectomy with silicone oil for retinal detachment repair. Finally, given the high risk of irreversible vision loss from amblyopia and recurrent retinal detachments in children with BOS and self-injurious behavior, the authors recommend regular 2-month interval ophthalmic follow-up.

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.

CHOROIDAL NEOVASCULARIZATION AND CHORIORETINAL ATROPHY IN A PATIENT WITH MELANOMA-ASSOCIATED RETINOPATHY AFTER IPILIMUMAB/NIVOLUMAB COMBINATION THERAPY.

PURPOSE: To describe a case of choroidal neovascularization (CNV) and chorioretinal scarring in a patient with melanoma-associated retinopathy after ipilimumab/nivolumab combination immune therapy for malignant melanoma. METHODS: Retrospective case report with fundus photography, fluorescein angiography, optical coherence tomography, and electroretinography. RESULTS: A 65-year-old woman presented with symptoms of photopsia and visual field loss. She had previously undergone ipilimumab/nivolumab combination chemotherapy treatment for malignant melanoma 14 months earlier coinciding with the onset of her visual symptoms. Fundus photography showed bilateral atrophic chorioretinal lesions and peripheral retinal pigment epithelial changes. Fluorescein angiography revealed retinovascular leakage in both eyes with CNV in the right eye. Optical coherence tomography showed a pigment epithelial detachment with subretinal fluid and subretinal hyperreflective material consistent with occult CNV. Visual field testing showed generalized visual field loss in both eyes. Bloodwork discovered an elevated angiotensin-converting enzyme. Electroretinography revealed abnormal peripheral rod and cone function with impairment of the photoreceptor and inner nuclear layer. Serum Western blot was positive for 60 kDa antiretinal autoantibody. After a single bevacizumab injection in the right eye, CNV resolved and visual acuity improved from 20/50 before the injection to 20/25 3 months after the injection. Visual acuity in the left eye deteriorated for months to counting fingers but then improved to 20/100 on follow-up examinations. CONCLUSION: Ipilimumab and nivolumab have been associated with immune-related ocular adverse effects. We report a case of combination therapy presenting with chorioretinal scarring and subsequent CNV in a patient with melanoma-associated retinopathy, a rare yet important adverse effect.

Traumatic Retinal Detachment in Patients with Self-Injurious Behavior: An International Multicenter Study.

PURPOSE: To describe the clinical characteristics, surgical outcomes, and management recommendations in patients with traumatic rhegmatogenous retinal detachment (RRD) resulting from self-injurious behavior (SIB). DESIGN: International, multicenter, retrospective, interventional case series. PARTICIPANTS: Patients with SIB from 23 centers with RRD in at least 1 eye. METHODS: Clinical histories, preoperative assessment, surgical details, postoperative management, behavioral intervention, and follow-up examination findings were reviewed. MAIN OUTCOME MEASURES: The rate of single-surgery anatomic success (SSAS) was the primary outcome. Other outcomes included new RRD in formerly attached eyes, final retinal reattachment, and final visual acuity. RESULTS: One hundred seven eyes with RRDs were included from 78 patients. Fifty-four percent of patients had bilateral RRD or phthisis bulbi in the fellow eye at final follow-up. The most common systemic diagnoses were autism spectrum disorder (35.9%) and trisomy 21 (21.8%) and the most common behavior was face hitting (74.4%). The average follow-up time was 3.3 ± 2.8 years, and surgical outcomes for operable eyes were restricted to patients with at least 3 months of follow-up (81 eyes). Primary initial surgeries were vitrectomy alone (33.3%), primary scleral buckle (SB; 26.9%), and vitrectomy with SB (39.7%), and 5 prophylactic SBs were placed. Twenty-three eyes (21.5%) with RRDs were inoperable. The SSAS was 23.1% without tamponade (37.2% if including silicone oil), and final reattachment was attained in 80% (36.3% without silicone oil tamponade). Funnel-configured RRD (P = 0.006) and the presence of grade C proliferative vitreoretinopathy (P = 0.002) correlated with re-detachment. The use of an SB predicted the final attachment rate during the initial surgery (P = 0.005) or at any surgery (P = 0.008. These associations held if restricting to 64 patients with ≥12 months followup. Anatomic reattachment correlated with better visual acuity (P < 0.001). CONCLUSIONS: RRD resulting from SIB poses therapeutic challenges because of limited patient cooperation, bilateral involvement, chronicity, and ongoing trauma in vulnerable and neglected patients. The surgical success rates were some of the lowest in the modern retinal detachment literature. The use of an SB may result in better outcomes, and visual function can be restored in some patients.

Retinal detachment repair with perfluoro-N-octane endotamponade in an infant with juvenile X-linked retinoschisis.

PURPOSE: We present a case of successful surgical management of an infant with X-linked retinoschisis with a giant retinal tear and retinal detachment of the right eye. OBSERVATIONS: A 10-month-old male presented with retinoschisis of both eyes and a retinal detachment of the right eye. The patient underwent two-stage pars plana vitrectomy utilizing perfluoro-N-octane to stabilize the detached retina and facilitate posterior hyaloid separation. Retained perfluoro-N-octane tamponade was later exchanged with silicone oil. The retina remained attached at last follow up. CONCLUSIONS AND IMPORTANCE: Retinal detachment repair in infants presents unique challenges. This is a safe and effective strategy for complex retinal detachment repair in the infant population.

Playing With Fire.

The authors present their concerns surrounding data presented in studies from 2018 and 2020 regarding very low dose bevacizumab for the treatment of retinopathy of prematurity. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:542-544.].

SAFER-ROP: Updated Protocol for Anti-VEGF Injections for Retinopathy of Prematurity.

BACKGROUND AND OBJECTIVE: To describe a safe and dependable protocol for intravitreal injections for the treatment of retinopathy of prematurity (ROP). MATERIALS AND METHODS: SAFER is an acronym used to describe the injection protocol and includes (S)hort needle (4-mm length), (A)ntiseptic/antibiotic (5% to 10% topical betadine), (F)ollowup (48 to 72 hours post-injection), (E)xtra attention to detail (clean environment, injection site 0.75 mm to 1.0 mm posterior to limbus), and (R)echeck (1 to 2 weeks following injection and until mature vascularization or laser). RESULTS: No cases of cataract formation, endophthalmitis, or vitreous hemorrhage using this technique were reported in a recent retrospective chart review. CONCLUSION: This protocol is a safe way to inject anti-vascular endothelial growth factor and to monitor ROP progression following injection.

Late-Onset Retinal Findings and Complications in Untreated Retinopathy of Prematurity.

PURPOSE: To investigate late retinal findings and complications of eyes with a history of retinopathy of prematurity (ROP) that did not meet treatment criteria and did not receive treatment during infancy. DESIGN: Retrospective, nonconsecutive, noncomparative, multicenter case series. PARTICIPANTS: Three hundred sixty-three eyes of 186 patients. METHODS: Data were requested from multiple providers on premature patients with a history of ROP and no treatment during infancy who demonstrated late retinal findings or complications and included age, gender, gestational age and weight, zone and stage at infancy, visual acuity, current retina vascularization status, vitreous character, presence of peripheral retinal findings such as lattice retinal tears and detachments (RDs), retinoschisis, and fluorescein findings. MAIN OUTCOME MEASURES: Rate of RDs and factors conferring a higher risk of RDs. RESULTS: The average age was 34.5 years (range, 7-76 years), average gestational age was 26.6 weeks (range, 23-34 weeks), and average birth weight was 875 g (range, 425-1590 g). Findings included lattice in 196 eyes (54.0%), atrophic holes in 126 eyes (34.7%), retinal tears in 111 eyes (30.6%), RDs in 140 eyes (38.6 %), tractional retinoschisis in 44 eyes (11.9%), and visible vitreous condensation ridge-like interface in 112 eyes (30.5%). Fluorescein angiography (FA) was performed in 113 eyes, of which 59 eyes (52.2%) showed leakage and 16 eyes (14.2%) showed neovascularization. Incomplete vascularization posterior to zone 3 was common (71.6% of eyes). Retinal detachments were more likely in patients with a gestational age of 29 weeks or less (P < 0.05) and in eyes with furthest vascularization to posterior zone 2 eyes compared with zone 3 eyes (P = 0.009). CONCLUSIONS: Eyes with ROP not meeting the treatment threshold during infancy showed various late retinal findings and complications, of which RDs were the most concerning. Complications were seen in all age groups, including patients born after the Early Treatment for Retinopathy of Prematurity Study. Contributing factors to RDs included atrophic holes within peripheral avascular retina, visible vitreous condensation ridge-like interface with residual traction, and premature vitreous syneresis. We recommend regular examinations and consideration of ultra-widefield FA examinations. Prospective studies are needed to explore the frequency of complications and benefit of prophylactic treatment and if eyes treated with anti-vascular endothelial growth factor therapy are at risk of similar findings and complications.
