ABSTRACT
PURPOSE: To evaluate the incidence of surgical intervention in pediatric intracranial hypertension (IH), evaluate the visual outcomes of surgically managed patients, and identify potential predictors for surgical intervention. METHODS: The medical records of patients with primary and secondary IH at Nationwide Children's Hospital from 2010 to 2017 were reviewed retrospectively. Presenting characteristics of medically and surgically managed patients were compared, and the clinical courses of surgically managed patients were reviewed. RESULTS: A total of 129 medically and 14 surgically managed patients were included. The surgical incidence was 9.8%. Final visual acuity in 27 of 28 surgically managed eyes was 20/25 or better. In combined primary and secondary IH patients, elevations in body mass index (BMI; OR = 1.06; 95% CI, 1.01-1.11; P = 0.022) and lumbar puncture opening pressures ≥52 cm H2O (OR = 6.17; 95% CI, 1.93-19.67; P = 0.002) were significantly associated with the likelihood of surgical intervention when assessed by univariate logistic regression; grade of papilledema >2 was of marginal significance. After controlling for BMI, a lumbar puncture opening pressure of ≥52 cm H2O was more likely to result in surgery (adjusted OR = 4.69; 95% CI = 1.39-15.98; P = 0.013). CONCLUSIONS: Most pediatric IH can be treated medically. Patients with lumbar puncture opening pressures ≥52 cm H2O at the time of diagnosis are at a higher risk of surgical intervention and should be monitored closely. Elevations in presenting BMI and grade of papilledema may also increase the odds of surgery.

PURPOSE: Intravitreal bevacizumab is increasingly used to treat severe retinopathy of prematurity (ROP), but it enters the bloodstream, and there is concern that it may alter development of other organs. Previously we reported short-term outcomes of 61 infants enrolled in a dose de-escalation study, and we report the late recurrences and additional treatments. DESIGN: Masked, multicenter, dose de-escalation study. PARTICIPANTS: A total of 61 premature infants with type 1 ROP. METHODS: If type 1 ROP was bilateral at enrollment, then the study eye was randomly selected. In the study eye, bevacizumab intravitreal injections were given at de-escalating doses of 0.25 mg, 0.125 mg, 0.063 mg, or 0.031 mg; if needed, fellow eyes received 1 dose level higher: 0.625 mg, 0.25 mg, 0.125 mg, or 0.063 mg, respectively. After 4 weeks, additional treatment was at the discretion of the investigator. MAIN OUTCOME MEASURES: Early and late ROP recurrences, additional treatments, and structural outcomes after 6 months. RESULTS: Of 61 study eyes, 25 (41%; 95% confidence interval [CI], 29%-54%) received additional treatment: 3 (5%; 95% CI, 1%-14%) for early failure (within 4 weeks), 11 (18%; 95% CI, 9%-30%) for late recurrence of ROP (after 4 weeks), and 11 (18%; 95% CI, 9%-30%) for persistent avascular retina. Re-treatment for early failure or late recurrence occurred in 2 of 11 eyes (18%; 95% CI, 2%-52%) treated with 0.25 mg, 4 of 16 eyes (25%; 95% CI, 7%-52%) treated with 0.125 mg, 8 of 24 eyes (33%; 95% CI, 16%-55%) treated with 0.063 mg, and 0 (0%; 95% CI, 0%-31%) of 10 eyes treated with 0.031 mg. By 6 months corrected age, 56 of 61 study eyes had regression of ROP with normal posterior poles, 1 study eye had developed a Stage 5 retinal detachment, and 4 infants had died of preexisting medical conditions. CONCLUSIONS: Retinal structural outcomes are very good after low-dose bevacizumab treatment for ROP, although many eyes received additional treatment.

Importance: There is a lack of literature describing the incidence of pediatric acute ocular injury and associated likelihood of vision loss in the United States. Understanding national pediatric eye injury trends may inform future efforts to prevent ocular trauma. Objective: To characterize pediatric acute ocular injury in the United States using data from a stratified, national sample of emergency department (ED) visits. Design, Setting, and Participants: A retrospective cohort study was conducted. Study participants received care at EDs included in the 2006 to 2014 Nationwide Emergency Department Sample, comprising 376â¯040 children aged 0 to 17 years with acute traumatic ocular injuries. Data were analyzed from June 2016 to March 2018. Exposures: International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes and external-cause-of-injury codes identified children with acute ocular injuries. Main Outcomes and Measures: Demographic and clinical characteristics of children with acute traumatic ocular injuries were collected and temporal trends in the incidence of ocular injuries by age, risk of vision loss, and mechanism of injury were explored. Results: In 2014, there were an estimated 163â¯431 (95% CI, 151â¯235-175â¯627) ED visits for pediatric acute ocular injury. Injured children were more often male (63.0%; 95% CI, 62.5-63.5) and in the youngest age category (birth to 4 years, 35.3%; 95% CI, 34.4-36.2; vs 10-14 years, 20.6%; 95% CI, 20.1-21.1). Injuries commonly resulted from a strike to the eye (22.5%; 95% CI, 21.3-23.8) and affected the adnexa (43.7%; 95% CI, 42.7-44.8). Most injuries had a low risk for vision loss (84.2%; 95% CI, 83.5-85.0), with only 1.3% (95% CI, 1.1-1.5) of injuries being high risk. Between 2006 and 2014, pediatric acute ocular injuries decreased by 26.1% (95% CI, -27.0 to -25.0). This decline existed across all patient demographic characteristics, injury patterns, and vision loss categories and for most mechanisms of injury. There were increases during the study in injuries related to sports (12.8%; 95% CI, 5.4-20.2) and household/domestic activities (20.7%; 95% CI, 16.2-25.2). The greatest decrease in high-risk injuries occurred with motor vehicle crashes (-79.8%; 95% CI, -85.8 to -74.9) and guns (-68.5%; 95% CI, -73.5 to -63.6). Conclusions and Relevance: This study demonstrated a decline in pediatric acute ocular injuries in the United States between 2006 and 2014. However, pediatric acute ocular injuries continue to be prevalent, and understanding these trends can help establish future prevention strategies.

BACKGROUND: The modified Dandy criteria and the newer diagnostic criteria for pseudotumor cerebri syndrome (PTCS) are both used to diagnose intracranial hypertension (IH). In comparison to the modified Dandy criteria, the PTCS criteria stratify the IH diagnosis into definite, probable, and suggested categories, exclude clinical symptoms, and use radiologic evidence for diagnosis. There is a lack of consensus on which criteria should be used in the pediatric population. The purpose of this study was to compare the diagnostic criteria for PTCS to the modified Dandy criteria and to identify limitations within both sets of criteria. METHODS: The PTCS criteria were retrospectively applied to 50 patients originally diagnosed with IH under the modified Dandy criteria. RESULTS: Of the 50 patients, 31 (62%) met diagnostic criteria for definite PTCS, 10 (20%) met criteria for probable PTCS, and 9 patients (18%) failed to meet sufficient PTCS criteria for diagnosis. CONCLUSIONS: Although the PTCS criteria use objective data to make the IH diagnosis, we found subjective symptoms to be useful indicators of disease in this group of patients. Additionally, distinguishing probable from definite IH may not have clinical relevance, because both groups were treated similarly. The absence of radiographic evidence of IH should not preclude a diagnosis of the condition, as it was present in a minority of patients included in this study. Further research is needed to clarify the disease process in patients who present with signs and symptoms of elevated intracranial pressure but lack ocular pathology.

There is no standard meaning of the term "vision therapy", and for this reason it is often a controversial topic between some members of the ophthalmic and optometric community. Most pediatric ophthalmologists avoid using the term because it is nonspecific. Convergence Insufficiency (CI) is a binocular visual problem that causes problems and symptoms with near fixation. There is consensus among eye care professionals that convergence therapy is effective in treating CI. Convergence therapy is not effective in treating learning disabilities, but can sometimes relieve symptoms that might be a barrier to reading.

PURPOSE: To investigate the effectiveness of 3 surgical preparation techniques in decreasing bacterial contamination of needles and suture material during strabismus surgery. METHODS: Consecutive patients requiring 2-muscle strabismus surgery were randomized into 1 of 3 groups. In Group A, patients' periocular skin and bulbar conjunctivae underwent preparation with 5% povidone-iodine; the drape was placed without regard to eyebrows; and an open wire-loop lid speculum was used. Group B patients underwent the same preparation as Group A patients; however, the eyelashes and eyebrows were scrubbed with 5% povidone-iodine on cotton tip applicators, and the drape was placed to exclude the eyebrows from the surgical field. Group C patients underwent the same preparation as Group B patients; however, a bladed lid speculum was used during surgery to exclude some of the eyelashes from the surgical field. After the procedure, all needles and suture materials were sent separately for aerobic culture. The data were analyzed for differences in contamination rates between the groups. RESULTS: Of 77 patients, 24 (31.4%) had either a needle and/or suture contaminant. Groups A, B, and C had mean contamination rates of 29.6%, 34.6%, and 29.2%, respectively. There was no significant statistical variation in contamination among the 3 groups. The most common organism identified was a coagulase-negative staphylococcus strain. CONCLUSIONS: More meticulous sterile preparation of the surgical field did not result in a meaningful reduction in suture or needle contamination rates during strabismus surgery.

PURPOSE: To determine the efficacy of a home-based computer orthoptic program to treat symptomatic convergence insufficiency. METHODS: A retrospective review of consecutive patients with symptomatic convergence insufficiency treated with a home-based computer orthoptic program was performed. Symptomatic convergence insufficiency was defined as: near point of convergence (NPC) >6 cm, decreased positive fusional vergence, exophoria at near at least 4(Δ) greater than at far, and documented complaints of asthenopia, diplopia, or headaches with reading or near work. The Computer Orthoptics CVS program was used for this study. Before beginning the computer orthoptic program, patients with an NPC >50 cm were given 4 base-in prisms and push-up exercises (NPC exercises with an accommodative target) for 2 weeks. RESULTS: A total of 42 patients were included. Mean treatment duration was 12.6 weeks; mean follow-up, 8.5 months. Of the 42 patients, 35 were treated with the home-based computer orthoptic program and push-up exercises; the remaining 7 only used the computer orthoptic program. Because of a remote NPC, 5 patients were given base-in Fresnel prism before starting treatment. Baseline mean NPC was 24.2 cm; posttreatment mean NPC improved to 5.6 cm: 39 patients (92.8%) achieved an NPC of ≤6 cm (p < 0.001). Positive fusional vergence improved in 39 patients (92.8%). Fourteen patients reduced their near exophoria by ≥5(Δ). A total of 27 patients (64.2%) reported resolution of symptoms after treatment. CONCLUSIONS: In our study, home-based computer orthoptic exercises reduced symptoms and improved NPC and fusional amplitudes. The computer orthoptic program is an effective option for treating symptomatic convergence insufficiency.

Patients with cystinosis have risk factors known to be associated with secondary increased intracranial pressure. The authors report a series of patients with cystinosis and describe their experience in the diagnosis and management of increased intracranial pressure in this population. The ophthalmologist should be aware of this vision-threatening association.

PURPOSE: To compare keratometry measurements on a fixating patient with readings from the same nonfixating patient intraoperatively using the Nidek KM-500 handheld keratometer. METHODS: Consecutive patients who were scheduled for strabismus or nasolacrimal surgery between 5 and 11 years of age were included in the study. Handheld keratometry was performed preoperatively on both eyes with the child fixating and intraoperatively with the child anesthetized. Three readings were taken on each eye. The steepest and flattest corneal meridians were recorded. Intraclass correlation coefficients were calculated to assess reliability, and interchangeability was assessed by the use of the Bland-Altman method. RESULTS: Included in the study were 55 eyes of 28 patients. The average fixating keratometry reading was 44.10 +/- 1.45 D for right eyes and 44.12 +/- 1.42 D for left eyes. The average nonfixating keratometry reading was 44.06 +/- 1.62 D for right eyes and 44.02 +/- 1.54 D for left eyes. The intraclass correlation coefficient for the average keratometry obtained fixating versus nonfixating was 0.96 for right eyes and 0.95 for left eyes. The Bland-Altman analysis showed fairly large limits of agreement between readings, but most readings fall within the limits of variability. The mean time to obtain the intraoperative measurements was 4.26 minutes. CONCLUSIONS: In our study the Nidek KM-500 handheld keratometer provided reliable readings when used intraoperatively on anesthetized nonfixating children and required minimal time to perform.

OBJECTIVE: To determine whether regional cerebral parenchymal injury patterns correlate with the distribution of retinal hemorrhages after inflicted head injury. STUDY DESIGN: Retrospective case series of funduscopic photographs and serial computerized tomographic imaging of 14 children with confirmed inflicted head injury. MAIN OUTCOME MEASURES: Retinal Hemorrhage Score per eye and per subject, visual field examination, regional patterns of parenchymal injury on computerized tomographic scans and necropsy, and retinal/optic nerve sheath hemorrhage distribution at necropsy. RESULTS: Ten of 14 children had retinal hemorrhages (71%); 90% were asymmetric (mean retinal score, 4.89 vs 2.56; P=.006). Retinal hemorrhages were maximal on the side of greatest cerebral injury in seven of 10 children initially. Subsequent imaging asymmetry predicted retinal hemorrhage distribution in all eight survivors. Children's Coma Scores, apnea or cardiorespiratory arrest, initial hemoglobin, and plasma glucose concentration did not predict laterality. Asymmetry was greatest if dilated ophthalmoscopy was performed during the first 24 hours (P=.03). Visual outcome was poor; three had homonymous hemianopia and four had cortical visual loss, all correlating with parenchymal atrophy patterns. CONCLUSION: The distribution of retinal hemorrhages after inflicted head injury correlates with acute and evolving regional cerebral parenchymal injury patterns.

OBJECTIVES: To determine the rate of progression from prethreshold to threshold retinopathy of prematurity (ROP) in infants excluded from Supplemental Therapeutic Oxygen for Prethreshold Retinopathy of Prematurity (STOP-ROP) because their median arterial oxygen saturation by pulse oximetry (SpO2) values were >94% in room air at the time of prethreshold diagnosis and to compare them with infants who were enrolled in STOP-ROP and had median SpO2 < or =94% in room air. METHODS: Fifteen of the 30 centers that participated in STOP-ROP elected to participate in the High Oxygen Percentage in Retinopathy of Prematurity study (HOPE-ROP) from January 1996 to March 1999. Infants were followed prospectively from the time prethreshold ROP was diagnosed until ROP either progressed to threshold in at least 1 study eye (adverse outcome) or resolved (favorable outcome). RESULTS: A total of 136 HOPE-ROP infants were compared with 229 STOP-ROP infants enrolled during the same time period from the same 15 hospitals. HOPE-ROP infants were of greater gestational age at birth (26.2 +/- 1.8 vs 25.2 +/- 1.4 weeks) and greater postmenstrual age at the time of prethreshold ROP diagnosis (36.7 +/- 2.5 vs 35.4 +/- 2.5 weeks). HOPE-ROP infants progressed to threshold ROP 25% of the time compared with 46% of STOP-ROP infants. After gestational age, race, postmenstrual age at prethreshold diagnosis, zone 1 disease, and plus disease at prethreshold diagnosis were controlled for, logistic regression analysis showed that HOPE-ROP infants progressed from prethreshold to threshold ROP less often than STOP-ROP infants (odds ratio: 0.607; 95% confidence interval: 0.359-1.026). CONCLUSIONS: The mechanisms that result in better ROP outcome for HOPE-ROP versus STOP-ROP are not fully understood. It seems that an infant's SpO2 value at the time of prethreshold diagnosis is a prognostic indicator for which infants may progress to severe ROP. When other known prognostic indicators are factored in, the SpO2 is of borderline significance.
