Retrospective evaluation of Postnatal Growth and Retinopathy of Prematurity (G-ROP) and Colorado Retinopathy of Prematurity (CO-ROP) screening algorithms in University of Pittsburgh Medical Centers cohort.

Of the 70,000 infants screened for retinopathy of prematurity (ROP) each year in the United States, only 43% develop any ROP, and <10% develop treatment-requiring ROP. Investigators have tried to develop new methods for determining more specific screening criteria, including the Postnatal Growth and Retinopathy of Prematurity (G-ROP) and Colorado Retinopathy of Prematurity (CO-ROP), to reduce the number of infants being screened while maintaining a high degree of sensitivity. We evaluated the records of 138 premature infants who received treatment for ROP between 2010 and 2021 with respect to G-ROP (129 infants) and CO-ROP (102 infants) to test the sensitivity of each. Using the G-ROP criteria, 0.8% (1/129) of treated infants had type 1 ROP that would have been missed and 3.1% (4/129) of total infants treated were missed. These infants would not have been screened or received treatment if G-ROP guidelines were followed. Using the CO-ROP criteria, 2% (2/102) of treated infants had type 1 ROP that would have been missed and 4.9% (5/102) of total infants treated were missed. In our study cohort, both sets of criteria proved less sensitive than our current screening guidelines.

The Relationship between Pinguecula and Diabetes Mellitus: A Comparative Cross-Sectional Study.

Purpose: To assess the relationship between diabetes mellitus (DM) and the presence of pinguecula and to identify other risk factors associated with pinguecula in patients attending the eye clinic at two tertiary university hospitals in Jordan. Methods: This was a comparative cross-sectional hospital-based study of 241 consecutive patients (122 patients with DM and 119 patients with no diabetes). All patients underwent complete ophthalmic examination, and data were collected regarding age, sex, occupational activity, presence and grade of pinguecula, glycosylated hemoglobin (HbA1c), and presence of diabetic retinopathy. Results: The mean (standard deviation, SD) ages of the DM and non-DM groups were 59.5 (10.8) years and 59.0 (11.6) years (p-value = 0.729), respectively. There was no significant difference in the prevalence of pinguecula between the diabetic and nondiabetic groups (66.4% vs. 66.5%, p = 0.998). Multivariate logistic regression analysis revealed that only outdoor occupational activity (OR = 5.16, 95% CI: 1.98-13.44, p = 0.001) was associated with increased prevalence of pinguecula. DM was not significantly associated with pinguecula (OR = 0.96, 95% confidence interval (CI): 0.55-1.67, p = 0.873). Neither age nor sex were significantly associated with pinguecula (p-value = 0.808, p-value = 0.390), respectively. Conclusion: DM was not significantly associated with the development of pinguecula in this Jordanian population. The prevalence of pinguecula was significantly associated with an outdoor occupational activity.

Thygeson's superficial punctate keratitis in children.

OBJECTIVE: To describe the first paediatric case series of Thygesons' superficial punctate keratitis (TSPK) with management outcomes. METHODS: A retrospective chart review was done for all children either diagnosed at initial presentation or referred with TSPK from 01/2012 to 08/2021 at a tertiary children's hospital. Records were assessed for signs, symptoms, diagnosis, steroid and cyclosporine 0.05% use. The main outcome measures were visual acuity, treatment response and total steroid exposure. RESULTS: Fifteen children (7 females), mean age at presentation 8 ± 4 years were included. All had bilateral disease and a BCVA of >20/40 in the better eye. All patients received topical fluorometholone 0.1%, (FML) initially. 80% had a good response to FML. Corneal scraping was done to exclude infectious causes in four cases due to poor initial response or clinical suspicion. All 4 needed EUA for scraping and anterior segment OCT, after which 2 had molecularly confirmed TGFBI-related stromal dystrophy. For the rest, slow steroid taper was done every 4-6 weeks and recurrences were treated by increasing steroid frequency. Cyclosporine 0.05% was started in nine patients (69%), 8 ± 6 months after initial presentation. The decrease in total steroid exposure per week after starting cyclosporine was statistically significant (p < 0.05). CONCLUSION: Children with TSPK respond quickly to steroids, however, recurrences are common, necessitating a slow taper. Non-response to steroid needs careful reconsideration of the diagnosis and may necessitate the use of an EUA. Using cyclosporine 0.05% reduces the total steroid exposure in TSPK.

Pediatric oral fluorescein angiography: a retrospective review from a single institution.

PURPOSE: To describe our experience with locally developed evidence-based guidelines for oral fluorescein angiography (FA) for retinal imaging in children. METHODS: The medical records of consecutive pediatric patients (≤18 years of age) at University of Pittsburgh Medical Center Children's Hospital Eye Center who underwent oral FA between November 1, 2018, and April 1, 2022, were reviewed retrospectively. Adherence to or deviation from the guidelines was noted at the time of testing. RESULTS: A total of 55 patients aged 3-18 with 79 examinations were included. No patient was excluded from the retrospective case review because of lack of recorded data. The main indications for oral FA included uveitis, retinal vasculopathy, disk pathology, and retinal lesions. Three children had transient side effects, and 1 had delayed urticaria 4 hours after examination. No child had anaphylaxis. One patient had suboptimal imaging due to nonadherence to the guidelines-recommended fasting protocol. All other examinations (78/79), where guidelines were followed, provided images adequate for clinical decision making. CONCLUSIONS: Based on our experience, we recommend that oral FA be considered, especially in children where intravenous access is less well tolerated while awake. Informed consent that includes the possibility of delayed side effects is advisable.

Safety of apraclonidine eye drops in diagnosis of Horner syndrome in an outpatient pediatric ophthalmology clinic.

PURPOSE: To describe the efficacy and systemic side effects of apraclonidine drops 0.5% in children clinically suspected of having Horner syndrome. METHODS: The medical records of patients with clinically suspected Horner syndrome who underwent testing with apraclonidine 0.5% eyedrops were reviewed retrospectively. The following data were retrieved from the record: allergic reactions, somnolence, shallow respiration, pallor, or excessive fussiness noted by the examiner or parents. RESULTS: A total of 46 patients presenting with anisocoria and tested with apraclonidine 0.5% were included. Of these, 15 had a positive result, with reversal of anisocoria. The mean age of patients was 3.2 years (median, 0.91; mode, 0.25 years). Twenty-four patients were ≤1 year of age; 19 were ≤6 months. No systemic side effects were noted during the examination or reported by parents in any patients. CONCLUSIONS: The use of topical apraclonidine eyedrops has been described as an effective test for Horner syndrome. However, concerns have been raised regarding the potential systemic side effects in children, especially those under the age of 6 months. In our cohort, no systemic side effects were reported, including in those under 6 months of age.

Traumatic Brain Injury in Children: Sport-related Concussions in Children.

Concussion is a worldwide health concern among children and adolescents. Over the decades concussion has been gradually better recognized as an entity that accounts for a significant disability post head trauma in patients. Patients present with cognitive, somatic and oculo-vestibular symptoms that can be incapacitating. Most concussion symptoms are transient and resolve within 1-2 weeks but can persist for years. Concussion pathophysiology is complex and may not be fully understood but it involves numerous mechanisms including cellular metabolic derangements, cerebral blood inflow, and axonal disruption. With no associated objective biomarkers or visible pathologic brain changes, diagnosis of concussion can be challenging. Many organizations and collaborative groups have suggested numerous definitions and diagnostic criteria for concussion in an attempt to improve the evidence-based clinical assessments and therapies for concussion. Proper assessment and evaluation is crucial starting from counseling of the patient, gradual return to cognitive and physical activity in an individualized treatment plan to ensure a timely return to daily activities and full sport participation. This report provides a grasp over the current state of sport-related concussion knowledge, diagnosis, and clinical evaluation in children and adolescent, with a focus on the ocular symptoms and signs.

The predictive value of magnetic resonance imaging of retinoblastoma for the likelihood of high-risk pathologic features.

PURPOSE:: To evaluate the predictive value of magnetic resonance imaging in retinoblastoma for the likelihood of high-risk pathologic features. METHODS:: A retrospective study of 64 eyes enucleated from 60 retinoblastoma patients. Contrast-enhanced magnetic resonance imaging was performed before enucleation. Main outcome measures included demographics, laterality, accuracy, sensitivity, and specificity of magnetic resonance imaging in detecting high-risk pathologic features. RESULTS:: Optic nerve invasion and choroidal invasion were seen microscopically in 34 (53%) and 28 (44%) eyes, respectively, while they were detected in magnetic resonance imaging in 22 (34%) and 15 (23%) eyes, respectively. The accuracy of magnetic resonance imaging in detecting prelaminar invasion was 77% (sensitivity 89%, specificity 98%), 56% for laminar invasion (sensitivity 27%, specificity 94%), 84% for postlaminar invasion (sensitivity 42%, specificity 98%), and 100% for optic cut edge invasion (sensitivity100%, specificity 100%). The accuracy of magnetic resonance imaging in detecting focal choroidal invasion was 48% (sensitivity 33%, specificity 97%), and 84% for massive choroidal invasion (sensitivity 53%, specificity 98%), and the accuracy in detecting extrascleral extension was 96% (sensitivity 67%, specificity 98%). CONCLUSIONS AND RELEVANCE:: Magnetic resonance imaging should not be the only method to stratify patients at high risk from those who are not, eventhough it can predict with high accuracy extensive postlaminar optic nerve invasion, massive choroidal invasion, and extrascleral tumor extension.
