Purpose To evaluate the quality, reliability, and safety-related content of Instagram videos on common ophthalmic emergencies. Methods This cross-sectional content analysis included 175 publicly available English-language Instagram videos across eight ophthalmic emergency topics. Two ophthalmologists independently assessed videos using the Journal of the American Medical Association (JAMA) Benchmark Criteria, Global Quality Score (GQS), and a study-specific exploratory Eye Safety Score (ESS). Misinformation, harmful advice, emergency referral guidance, red-flag information, creator type, and engagement were recorded. Adjusted ordinal regression evaluated associations between engagement and ESS while accounting for topic, creator category, and repeated creators. Results Mean JAMA, GQS, and ESS values were 2.55 ± 0.52, 2.96 ± 0.77, and 3.07 ± 1.18. Misinformation occurred in 10.9% of videos, harmful advice in 9.7%, emergency referral guidance in 64.0%, and red-flag information in 63.4%. Ophthalmologist-authored videos had higher reliability and quality scores and no detected misinformation in this sample. Views and likes showed weak inverse correlations with ESS; adjusted associations remained significant (views: adjusted odds ratio [aOR] = 0.47, 95% confidence interval [CI] 0.29–0.75; likes: aOR = 0.38, 95% CI 0.22–0.66). Conclusion In this cross-sectional sample of English-language Instagram videos on ophthalmic emergencies, safety-related omissions were common. Higher engagement was associated with lower ESS, but the cross-sectional design precludes causal inference.
Background To report intraocular pressure (IOP) changes after non-primary (NPR) and primary retinectomy (PR), to assess a correlation between final IOP and the length of retinectomy. Methods Retrospective cohort study: 99 consecutive patients who underwent retinectomies for rhegmatogenous retinal detachment complicated by proliferative vitreoretinopathy between 2014–2021. Results Mean final IOP was 13.79 ± 6.60 and 15.18 ± 9.62 mmHg among NPRs and PRs respectively, the difference with mean preoperative IOPs (16.64 ± 8.99 mmHg and 12.22 ± 4.54 mmHg among NPRs and PRs respectively) was significant among NPRs (p = 0.013). No differences were found between mean final IOP of eyes without SO and with SO in situ in both groups (p = 0.333, p = 0.123). The mean retinectomy extent was 5.06 ± 2.11 clock hours among NPRs and 7.36 ± 3.28 clock hours among PRs, the difference was significant (p < 0.001) . A significant inverse correlation was found between retinectomy length and final IOP in cases which underwent successful removal of silicone oil (ROSO) post-retinectomy (p = 0.038), in cases with oil in situ at last follow-up (p = 0.035) and among NPRs (p = 0.022). Conclusion final IOP significantly diminished after NPR. Retinectomy length was shorter among NPRs, and significantly inversely correlated with final IOP in cases that underwent successful ROSO, with oil in situ at final follow-up and in NPRs.
Purpose To describe a novel technique for repositioning dislocated rigid C-loop polymethyl methacrylate (PMMA) intraocular lenses (IOLs) without eyelets using a double-rectangle 10–0 prolene suture configuration. Methods This retrospective observational study included six eyes of patients with dislocated rigid C-loop PMMA IOLs in the vitreous cavity. All eyes underwent pars plana vitrectomy and repositioning of the existing IOL using a double-rectangle 10–0 prolene suture configuration, securing the IOL between the suture and the iris. Postoperative evaluation included best-corrected visual acuity (BCVA), slit-lamp biomicroscopy, fundoscopy, anterior segment optical coherence tomography (AS-OCT), and posterior segment OCT. IOL tilt and postoperative complications were assessed during follow-up. Results At 12 months follow up all six IOLs were successfully repositioned intraoperatively. No complete IOL redislocation occurred during the available follow-up. Final BCVA was 0.14 ± 0.08 logMAR, and the mean IOL tilt was 2.43° ± 1.58°. A myopic refractive shift of 1.75 ± 0.22 D was observed compared with the pre-dislocation refraction. One eye (16.7%) developed partial inferior IOL subluxation, without associated visual or refractive deterioration, and two eyes (33.3%) developed cystoid macular edema, resolved with treatment. Conclusion In this small proof-of-concept series, the double-rectangle 10–0 prolene suture technique allowed repositioning of dislocated rigid C-loop PMMA IOLs while avoiding a large corneal incision and was associated with favorable short-term anatomical outcomes. The occurrence of CME and partial IOL subluxation highlights the need for careful postoperative monitoring. Larger studies with longer follow-up are required to determine the long-term stability, safety, and reproducibility of the technique.
Background Myopia is an increasing global public health concern, particularly in East Asia. Cylindrical Annular Refractive Element (CARE) spectacle lenses aim to slow myopia progression by inducing peripheral myopic defocus. This meta-analysis evaluates the efficacy and safety of CARE lenses versus single-vision spectacle lenses in children. Methods We conducted a systematic search for randomized controlled trials comparing CARE spectacle lenses to single-vision lenses in children with myopia. Primary outcomes were mean change in spherical equivalent refraction and axial length. All analyses were performed using R software. Pooled mean differences and risk ratios with 95% confidence intervals were calculated using a random-effects model. Results At 12 months, CARE lenses significantly reduced myopia progression compared to single-vision lenses. The treatment effect increased with longer follow-up, with one study reporting sustained benefit at 24 months. CARE lenses were associated with a significantly lower risk of fast progression. No significant differences were observed between groups in visual acuity change or discontinuation rates. Conclusion CARE spectacle lenses may be a well-tolerated, non-invasive option for slowing myopia progression in children, with modest benefits observed over one to two years. Larger, longer-term RCTs in diverse populations are needed to confirm these findings and establish sustained efficacy.
