Purpose: To evaluate the quality, reliability, and readability of online patient educational materials on leukocoria.

Methods: In this cross-sectional study, the Google search engine was searched for the terms "leukocoria" and "white pupil." The first 50 search outcomes were evaluated for each search term based on predefined inclusion criteria, excluding duplicates, peer-reviewed papers, forum posts, paywalled content, and multimedia links. Sources were categorized as "institutional" or "private." Three independent raters assessed each web-site for quality and reliability using DISCERN, Health on the Net Code of Conduct (HONcode), and JAMA criteria. Readability was evaluated using seven formulas: Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG) Index, Automated Readability Index (ARI), Linsear Write (LW), Gunning Fog Index (GFI), and Coleman-Liau Index (CLI).

Results: A total of 51 websites were included. Quality, assessed by the DISCERN tool, showed a median score of 4, denoting moderate to high quality, with no significant differences between institutional and private sites or search terms. HONcode scores indicated variable reliability and trustworthiness (median: 10, range: 3 to 16), with institutional sites excelling in financial disclosure and ad differentiation. Additionally, institutional and private sites performed well in reliability and accountability, as measured by the JAMA Benchmark criteria (median: 3; range: 1 to 4). Readability, averaging an 11.3 ± 3.7 grade level, did not differ significantly between site types or search terms, consistently falling short of the recommended sixth-grade level for patient educational materials.

Conclusions: The patient educational materials on leukocoria demonstrated moderate to high quality, commendable reliability, and accountability. However, the readability scores were above the recommended level for the layperson. [J Pediatr Ophthalmol Strabismus. 2024;61(5):332-338.].

Purpose: To evaluate the incidence, risk factors, and development of retinopathy of prematurity (ROP) in midpreterm and late-preterm infants born at 32 to 36 6/7 weeks of gestational age.

Methods: The ophthalmic examination findings and risk factors of 5,477 preterm infants who underwent ophthalmological examination were evaluated retrospectively. The rates of any stage and severe ROP (requiring treatment) development and treatment options were recorded. The risk factors were analyzed by using logistic regression analysis.

Results: A total of 5,477 infants were included in the study, of whom 2,715 (49.57%) were mid-preterm and 2,762 (50.43%) were late-preterm. The rates of any stage and severe ROP were 8.2% (n = 223) and 0.6% (n = 15) in mid-preterm infants, respectively. In late-preterm infants, the rate of any stage ROP was 2.1% (n = 59), and no severe ROP was detected. There was no significant difference in mean birth weight in mid-preterm infants between infants with any stage ROP and severe ROP (P = .104). Of the 15 infants (0.3%) who required treatment, 14 (0.2%) infants had laser photocoagulation, 1 (0.01%) had intravitreal bevacizumab, and 2 (0.03%) had additional therapy (laser photocoagulation and intravitreal bevacizumab). In logistic regression analysis, a significant association was found between treatment requirement and transport from an external center (P < .001, ß = 0.04).

Conclusions: Although ROP development rates decrease as birth weight and gestational age increase, late-preterm infants should be examined for ROP at least once, especially those born in low-income countries because ROP development can still be observed.

Purpose: To evaluate the efficacy and safety of oral azithromycin treatment combined with topical antibiotic and anti-inflammatory agents in pediatric patients with chronic severe bilateral blepharokeratoconjunctivitis.

Methods: Patients younger than 14 years with chronic and severe bilateral blepharokeratoconjunctivitis were reviewed retrospectively. Consecutive patients receiving oral azithromycin treatment were included. All patients received oral azithromycin (5 mg/kg/single dose daily) for at least 4 weeks combined with topical antibiotic and anti-inflammatory agents. Before and after the treatment, clinical symptoms were noted, and corneal and conjunctival fluorescein staining and corneal neovascularization were graded. Meibomian gland secretion and meibomian gland plugging were also assessed. All patients completed at least 3 months of follow-up after completion of the oral azithromycin treatment. Patients' clinical data at the time of diagnosis and last follow-up visit were statistically compared.

Results: Twenty-nine children (58 eyes, mean age of 6.51 years) were included. The mean time of oral azithromycin use was 5.87 weeks (range: 4 to 10 weeks). Clinical symptoms and signs and visual acuity were significantly improved after treatment. The mean fluorescein staining and corneal neovascularization grades and meibomian gland secretion and meibomian gland plugging scores also improved after treatment (P < .001). Eyelid distortion or fornix shortening was not observed. At the last follow-up visit, all patients were stable with treatment only with daily eyelid hygiene, topical cyclosporine, and artificial tears.

Conclusions: Long-term, low-dose oral azithromycin combined with topical antibiotic and anti-inflammatory agents is an effective treatment option for pediatric patients with chronic severe bilateral blepharokeratoconjunctivitis. [J Pediatr Ophthalmol Strabismus. 2024;61(5):358-364.].

Purpose: To evaluate the effect of botulinum toxin A injection on the frequency of horizontal nystagmus in children.

Methods: This was a non-randomized before-and-after clinical trial evaluating a cohort of children with horizontal nystagmus before and after treatment with botulinum toxin A. The toxin was injected under general anesthesia with spontaneous ventilation without intubation using the Mendonça forceps and the effect was evaluated by analyzing the frequency of the oscillation in Hertz (Hz) on video registrations before and after treatment.

Results: The current study found a statistically significant difference on the frequency of the nystagmus in children before and after the injection of botulinum toxin A, with the mean frequency decreasing from 1.55 ± 0.94 Hz before treatment to 1.04 ± 0.87 Hz at 1 month post-injection (P < .001) and to 1.27 ± 0.87 Hz at 6 months post-injection (P = .002). When comparing the data 1 and 6 months post-injection, this study found a significant increase (P = .001) in the frequency of the nystagmus.

Conclusions: The injection of botulinum toxin A is effective in reducing the frequency of oscillations in children with horizontal nystagmus both 1 and 6 months after the procedure, and can be used as a first-line, less invasive treatment aiming to decrease the frequency of oscillation.

The authors report a case of bilateral cataract in a 9-year-old girl after being treated with a combination of the targeted therapy drugs dabrafenib and trametinib. Although adverse effects have been reported with this treatment, this report is the first documented case of cataract as a complication. [J Pediatr Ophthalmol Strabismus. 2024;61(5):e47-e49.].

Patients with keratoconus may lack sufficient understanding of their illness. The authors assessed the accuracy and readability of ChatGPT (OpenAI) responses to common questions regarding keratoconus and found that the provided data are precise, with minor inaccuracies. The complexity of responses requires a high reading level, which may be unsuitable for many patients. [J Pediatr Ophthalmol Strabismus. 2024;61(5):e43-e46.].

Purpose: To analyze the motor and sensory outcomes of strabismus surgery in children born preterm (premature group) and full-term (control group).

Methods: The study was performed at a tertiary university hospital. Children who underwent strabismus surgery between 2012 and 2019 were retrospectively reviewed. The success of surgery, postoperative over-correction and undercorrection rates, and stereopsis and fusion test results were compared between the premature and control groups.

Results: There were 70 patients in the premature group (mean gestational age: 31.25 weeks; range: 24 to 35 weeks) and 242 patients in the control group. The amounts of preoperative and postoperative deviations and overcorrection, undercorrection, and success rates were similar between the premature and control groups (P > .05). Stereopsis improved from 560 to 300 arc/sec postoperatively in the premature group (P = .066) and from 1,156 to 685 arc/sec in the control group (P < .001). The rate of fusion increased from 12.5% to 25% in the premature group (P = .50) and from 17% to 47% in the control group (P < .001). The analysis of strabismus subgroups revealed significant improvement of fusion in full-term patients (P < .001) and not in preterm patients (P = .50) with esotropia. Preoperative amount of deviation was the only risk factor for surgical success (P < .001). Age, sex, history of prematurity, and spherical equivalent refraction were not correlated with undercorrection (P > .05).

Conclusions: Regardless of the type of strabismus, although the functional results after strabismus surgery were similar in preterm and full-term patients, the gain of stereopsis and central fusion was significantly higher in full-term patients compared to preterm patients.
