Abstract
Background
The vitreous evolves from birth over lifetime. Little is known about the appearance of the healthy vitreous during childhood. We aimed to characterise posterior vitreous features in healthy children using spectral domain optical coherence tomography (SD-OCT).
Methods
Retrospective cohort study including healthy eyes of 78 children aged 2–12 years and 39 healthy adults. Patients diagnosed with intraocular inflammation or vitreoretinal pathology were excluded.
Main Outcome: Proportion of eyes with presence of punctate hyperreflective vitreous opacities (PHVO). Percentage of B-scans demonstrating PHVO within an OCT volume scan, correlation between presence of PHVO and patients’ age group, retinal measurements, and presence of premacular bursa were analysed.
Results
154 paediatric eyes (median age 9.08 (IQR 5.17–9.75) years) and 76 adult eyes (30.75 (IQR 26.42–38.08) years) were included; 12244 OCT images were reviewed. All eyes (100%) in the paediatric group and 73% in the adult group presented PHVO. The median percentage of OCT images showing PHVO was 77.05% (IQR 51.23–88.52) in children and 8.0% (IQR 0–16.03) in adults (p < 0.001). Separate analysis of right and left eyes confirmed the results (p < 0001). Premacular bursa appeared in 20.5% of paediatric and 31.6% of adult eyes (p = 0.103). Mean central subfield thickness was significantly lower in children (257 ± 21 µm vs. 276 ± 18 µm, p < 0.001), while median total macular volume was similar (8.59 (IQR 8.25–8.86) mm3 vs. 8.62 (IQR 8.39–8.96) mm3, p = 0.145).
Conclusions
This study demonstrates that PHVO are ubiquitous physiologic vitreous findings in healthy children beyond infancy. These findings enhance the understanding of the development of the posterior segment of the eye and might improve paediatric OCT interpretation, potentially avoiding misdiagnoses and unnecessary interventions in children.
