RESUMEN

PURPOSE: To identify pediatric patient and appointment characteristics associated with no-show status at a tertiary care pediatric ophthalmology clinic within a U.S. academic ophthalmology department. METHODS: A cross-sectional retrospective chart review was performed for all pediatric patients with a scheduled ophthalmology appointment at the Penn State Eye Center between April 1, 2022 and March 31, 2023. A multivariate logistic regression analysis assessed associations between appointment nonattendance and patient characteristics. RESULTS: Of 8,083 scheduled visits, 1,445 (17.9%) were no-shows. Factors associated with no-show status included appointment type (new vs return odds ratio [OR]: 1.43, 95% CI: 1.26 to 1.63, P < .001); lower median household income (< $41,374 vs > $68,957 OR: 1.89, 95% CI: 1.40 to 2.55, P < .001; $41,374 to $68,957 vs > $68,957 OR: 1.27, 95% CI: 1.12 to 1.44, P < .001); non-private insurance (self-pay vs private: OR: 5.65, 95% CI: 3.87 to 8.24, P < .001, Medicaid vs private: OR: 2.17, 95% CI: 2.32 to 3.16, P < .001); commute distance 10 to 30 miles vs < 5 miles (OR: 1.49, 95% CI: 1.11 to 1.99, P = .008); race: unavailable vs White (OR: 2.18, 95% CI: 1.66 to 2.85, P < .001), Black vs White (OR: 1.86, 95% CI:1.53 to 2.27, P < .001), Other vs White (OR: 1.47, 95% CI: 1.27 to 1.70, P < .001); ethnicity: Hispanic vs non-Hispanic (OR: 1.92, 95% CI: 1.62 to 2.27, P < .001); and language preference: Spanish vs English (OR: 1.86, 95% CI: 1.49 to 2.32, P < .001), Nepali vs English (OR: 1.60, 95% CI: 1.06 to 2.43, P = .027), other vs English (OR: 1.83, 95% CI: 1.35 to 2.49, P < .001). Appointment reminders (phone call, P = .013); text message, P < .001; other, P = .013) all resulted in a greater propensity to show, but email communication alone did not (P = .674). CONCLUSIONS: Certain patient and appointment characteristics that are linked to a higher rate of no-show status can inform targeted initiatives to improve health care outcomes, resource utilization, and clinical efficiency in the pediatric ophthalmology community.

RESUMEN

PURPOSE: To assess pediatric ophthalmology-related information on TikTok (ByteDance). METHODS: The 12 most commonly searched terms from the American Association for Pediatric Ophthalmology and Strabismus website were queried as TikTok hashtags. The top 20 videos for each hashtag were analyzed for views, likes, comments, saves, shares, author status and gender, content, and engagement level ratio (ELR). Subanalysis of the educational videos for quality, understandability and actionability, and medical accuracy using the modified DISCERN (mDISCERN), Patient Education Materials Assessment Tool (PEMAT), and modified Medical Information and Content Index (mMICI) was performed. RESULTS: Analysis of 222 videos revealed a cumulative 191,337,973 views. Patients/families created the most videos (60.4%), followed by optometrists (14.4%), other (laypeople/unknown) (9.0%), ophthalmologists (7.7%), non-ophthalmology physicians (4.5%), and nurses (4.1%). Content was predominantly patient experience (56.8%), followed by educational (25.2%), humor (11.7%), self-promotional (3.6%), procedures (0.9%), other (0.9%), advertisements (0.5%), and career (0.5%). Educational videos had a lower ELR than humorous (3.3 vs 8.2, P < .001) and patient experience (3.3 vs 5.3, P < .001) videos, but more saves than patient experience videos (74 vs 25, P = .009). The mDISCERN scores were greater for videos authored by ophthalmologists (3, P < .001) and optometrists (2.5, P < .001) compared to lay-people (1.5). Ophthalmologist PEMAT understandability scores were greater than non-ophthalmology providers' (95.5% vs 67.4%, P = .002). There was no difference in PEMAT actionability (P = .743) or mMICI scores among the author subgroups (P = .206). CONCLUSIONS: Pediatric ophthalmology content on Tik-Tok ranges in quality and understandability. Additional research is needed to help promote posts created by eyecare providers to ensure evidence-based medical content reaches pediatric patients and their families.

RESUMEN

We present a novel approach for performing an Nd:YAG laser posterior capsulotomy under general anesthesia with the patent in a seated position. We illustrate this approach in 2 cases, a young child and an adult patient with developmental delay. This technique may facilitate YAG capsulotomy in patients who cannot sit for the procedure.

RESUMEN

BACKGROUND: The Pediatric Examination Assessment Rubric (PEAR) toolkit consists of an examination sheet and rubric designed to assess ophthalmology residents' performance on the pediatric eye examination. The purpose of this study was to evaluate the reliability of the PEAR toolkit. METHODS: Six ophthalmology residents (2 PGY-2, 4 PGY-3) at a single ACGME-accredited US program participated in 11 video-recorded pediatric ophthalmology patient encounters. Two pediatric ophthalmologists reviewed the videos and the residents' examination sheets to complete a PEAR evaluation. The inter-rater reliability of the rating for each of the 12 examination skills evaluated using PEAR was determined using kappa statistics, and reliability strength was categorized based on published guidelines (≤0, poor; 0-0.20, slight; 0.21-0.40, fair; 0.41-0.60, moderate; 0.41-0.60, substantial; 0.81-1.00, almost perfect). RESULTS: Eleven video encounters were completed. Of the 12 examination skills evaluated using PEAR, 9 had kappa scores with strengths of moderate to almost perfect reliability. Two examination skills, Worth 4-Dot and alignment, showed fair reliability. A kappa score could not be calculated for stereoacuity because of the lack of variability among the evaluators' raw scores. CONCLUSIONS: In our small sample of residents from a single institution, the PEAR toolkit showed inter-rater reliability.

RESUMEN

PURPOSE: The purpose of this study was to report a case of Propionibacterium acnes endophthalmitis in a patient with a Baerveldt glaucoma implant. PATIENTS AND METHODS: An 8-year-old boy presented with left eye pain, extreme photophobia, and acute anterior uveitis >6 months after Baerveldt glaucoma implantation. A diagnosis of P. acnes endophthalmitis was made after a positive culture of the explanted Baerveldt device. RESULTS: Initially, the patient was treated with intravitreal vancomycin and ceftazidime which led to mild early clinical improvement followed by deterioration of findings with recurrence of fibrin at the Baerveldt tube ostium within the anterior chamber. Repeat intravitreal injections were given to include antifungal coverage, along with intracameral moxifloxacin and subconjunctival vancomycin around the Baerveldt reservoir. Symptoms and findings again recurred, ultimately leading to the decision for complete removal of the glaucoma implant along with irrigation of the scleral bed with moxifloxacin. P. acnes was cultured from the extracted implant. The endophthalmitis resolved completely after implant removal. CONCLUSIONS: Despite the introduction of antibiotics into the intravitreal, intracameral, and subconjunctival space surrounding the Baerveldt implant, infection persisted until complete explantation of the device. Early explantation should be considered in glaucoma drainage device endophthamitis secondary to P. acnes.

RESUMEN

We report a case exhibiting the coexistence of anterior and posterior segment pathology in the same eye secondary to a congenital disorder of glycosylation resulting from a DPAGT1 gene mutation. This case details a novel gene mutation in a male infant found to have bilateral congenital cataracts, removed at 6 and 7 weeks of life, only to uncover bilateral retinal and optic atrophy. Our report highlights issues of surgical timing for syndrome-related pediatric cataracts, given the risks related to secondary glaucoma versus deprivation amblyopia, in an infant born with both cataracts and vision-limiting posterior segment pathology.

RESUMEN

BACKGROUND: Tonometry in the anesthetized child, vital for evaluating known or suspected glaucoma, remains limited to tonometers capable of supine recording. The Icare PRO measures intraocular pressure (IOP) in the sitting or supine patient. The purpose of this study was to compare Icare PRO and Tono-Pen tonometry during examination under anesthesia in eyes of supine children with normal eyes and glaucoma and/or corneal pathology. METHODS: In this prospective study of children undergoing examination under anesthesia, IOP was recorded in both eyes with Icare PRO and Tono-Pen immediately after mask anesthesia induction, with instrument order randomized. RESULTS: A total of 100 eyes of 50 children (median age, 58 months) were included. IOP range was 6-50 mm Hg by Icare PRO and 6-53 mm Hg by Tono-Pen. Mean IOP measured by Tono-Pen (18.9 ± 7.5) was higher than that measured by Icare PRO (16.7 ± 7.1 mm Hg) by 2.2 mm Hg (P < 0.001). The presence of corneal edema was associated with IOP measurements higher by Tono-Pen than by Icare PRO (mean difference, 8.4 mm Hg). When eyes with corneal edema were excluded from analysis, there was no correlation between central corneal thickness and the difference in IOP between the two instruments. CONCLUSIONS: IOP in eyes of supine children under anesthesia measured approximately 2 mm Hg higher by Tono-Pen than Icare PRO and this difference was greater in eyes with frank corneal edema. Icare PRO may become a valuable tool for tonometry in supine infants and children, but a confirmatory test should be considered in eyes with corneal edema.

RESUMEN

PURPOSE: To determine whether objective visual function, measured by swept-parameter visual evoked potential (sVEP), is preferentially degraded by neutral density filtration (NDF) in normal control and fellow eyes compared to amblyopic eyes, and to determine whether the response to NDF is a function of stimulus type, using grating and vernier stimuli. METHODS: Monocular Snellen acuity and both grating and vernier sVEP responses were measured in each eye of 23 children or adolescents with amblyopia and 21 visually and neurologically normal children or adolescents. Acuity and sVEP responses were measured with and without a 2.0 log unit neutral density filter before the viewing eye. RESULTS: Suprathreshold sVEP grating responses were more sensitive than vernier to degradation by amblyopia in the unfiltered state and to NDF-induced preferential degradation of responses from fellow and normal control eyes. For threshold measurements, on the other hand, vernier responses were more sensitive to degradation by amblyopia in the unfiltered state and to NDF-induced preferential depression. Threshold vernier responses of amblyopic eyes were paradoxically enhanced by NDF. CONCLUSIONS: Neutral density filtration causes preferential degradation of both threshold and suprathreshold sVEP responses in normal control eyes and fellow eyes of amblyopes, compared to amblyopic eyes. The degradation is stimulus specific and dependent upon whether threshold or suprathreshold responses are measured. Grating responses are more likely to identify suprathreshold abnormalities, while vernier stimuli are more likely to detect threshold abnormalities. These findings may be used to optimize the stimulus parameters and design of future studies utilizing evoked potential techniques in amblyopic subjects.

RESUMEN

PURPOSE: To identify optic nerve head (ONH) cupping reversal and associated optical coherence tomography (OCT) and Humphrey visual field changes in pediatric glaucoma. DESIGN: Retrospective observational case series. METHODS: Sequential surgical cases of juvenile open-angle glaucoma (OAG) or primary congenital glaucoma (PCG) with sustained postoperative intraocular pressure (IOP) reduction. Group 1 had preoperative and postoperative ONH photographs and OCT; Group 2 had preoperative clinical ONH assessment and postoperative imaging. Cupping evaluation was confirmed by masked glaucoma and neuro-ophthalmology specialists. RESULTS: Of 80 cases, 9 eyes (9 children) met criteria for Group 1; 24 eyes (19 children) met criteria for Group 2. Group 1: Five of 9 eyes (56%) demonstrated cupping reversal, with preoperative vs postoperative mean IOP 34.2 ± 6.6 mm Hg vs 10.6 ± 4.1 mm Hg (P < .00001) and mean average retinal nerve fiber layer (RNFL) 71.0 ± 30 µm vs 62.8 ± 24 µm (P = .4), respectively. RNFL was stable in 4 of 5 eyes (all juvenile OAG), but thinned (Δ = -41 µm) in 1 eye with PCG. Humphrey visual fields (reliable in 2 of 3 eyes) showed no significant change. Group 2: Fourteen of 24 PCG eyes (58%) demonstrated cupping reversal, with preoperative vs postoperative mean IOP 36.1 ± 8.9 mm Hg vs 13.3 ± 2.1 mm Hg (P < .00001). Two eyes had thin RNFL postoperatively despite healthy-appearing ONH. Postoperative RNFL showed statistically significant linear correlation with preoperative (but not postoperative) cup-to-disc ratio. Limitations include small numbers, few reliable Humphrey visual fields, and absent preoperative imaging (Group 2). CONCLUSION: Some eyes with IOP reduction and ONH cupping reversal show continued RNFL thinning postoperatively. The preoperative ONH cup-to-disc ratio predicted the postoperative RNFL better than the postoperative "reversed and smaller" cup-to-disc ratio. Cupping reversal in pediatric glaucoma may not predict improved ONH health and deserves further study.

RESUMEN

PURPOSE: To evaluate the SureSight autorefractor and compare it to the plusoptiX A09 photoscreener in the detection of amblyopia risk factors in a cohort of Honduran children examined during medical mission work and to assess the utility of both devices in the rural setting. METHODS: The medical records of patients who had undergone SureSight autorefractor screening, plusoptiX photoscreening, and a gold standard pediatric ophthalmology examination, including cycloplegic refraction, during a recent medical mission trip to Honduras were retrospectively reviewed. RESULTS: A total of 216 children were examined. Of these, 9 (4%) were found to have amblyopia risk factors based on the current referral criteria of the American Association for Pediatric Ophthalmology and Strabismus on ophthalmological examination. The plusoptiX was found to have 89% sensitivity and 80% specificity; the SureSight, using manufacturer's referral criteria, was found to have sensitivity of 89% and specificity of 71%. CONCLUSIONS: Both devices were found to be reliable vision screening devices when used on the general population of remote villages in Honduras, although the specificity of the plusoptiX A09 was higher.
