Insights
Tessellated fundus occurs in over 30% of preschool children, even in those without myopia. This finding in young children is linked to longer axial length and larger corneal curvature radius.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Ocular Imaging
Background:
- Tessellated fundus, characterized by visible choroidal vessels, can be present in healthy eyes.
- Its prevalence and associated factors in young children require further investigation.
Purpose of the Study:
- To determine the occurrence of tessellated fundus in preschool children aged 3-6 years.
- To identify factors influencing the presence of tessellated fundus in this age group.
Main Methods:
- A cross-sectional study involving 1716 preschool children (3-6 years old).
- Comprehensive eye examinations and questionnaires were administered.
- Fundus photographs were used to grade peripapillary tessellation based on optic disc involvement.
Main Results:
- Peripapillary tessellation was observed in 35.0% of the children.
- The prevalence was 33.0% in hyperopia, 38.0% in pre-myopia, and 50.7% in myopia.
- In non-myopic children, tessellated fundus correlated with longer axial length and larger corneal radius of curvature.
Conclusions:
- Over 30% of preschool children exhibit peripapillary tessellated fundus.
- Tessellated fundus is not exclusive to myopic children and is associated with axial length and corneal curvature.
- Findings highlight the importance of considering ocular biometry in the assessment of tessellated fundus in young children.
Background/Objectives:
Tessellated fundus can exist in normal healthy eyes. This study aims to evaluate the occurrence and influencing factors of tessellated fundus in preschool children aged 3-6 years.
Subjects/Methods:
This kindergarten-based cross-sectional study included 1716 children with an age range of 3-6 years. All participants underwent a comprehensive eye examination and a questionnaire. According to the number of quadrants occupied by tessellated fundus around the optic disc in fundus photographs, it was divided into four grades.
Results:
600 (35.0%) children had peripapillary tessellation. According to the spherical equivalent (SE), the subjects were divided into three groups: Hyperopia group (SE > + 0.75D, n = 1194)；Pre-myopia group (-0.50D < SE ≤ + 0.75D, n = 455); Myopia group (SE ≤ -0.50D, n = 67). The proportion of peripapillary tessellated fundus was 33.0%, 38.0%, 50.7% respectively. According to the regression analysis, in the non-myopia group (Pre-myopia group and Hyperopia group), the occurrence of peripapillary tessellated fundus was associated with longer axial length (OR, 1.566; 95% CI: 1.229-1.996, p < 0.001) and larger corneal radius of curvature (OR, 1.837; 95% CI: 1.006-3.354, p = 0.048). However, in Pre-myopia group, the corneal radius of curvature was not associated with the occurrence of peripapillary tessellated fundus (p = 0.830). In Hyperopia group, the corneal radius of curvature was associated with the occurrence of peripapillary tessellated fundus (OR, 2.438; 95% CI: 1.160-5.122, p = 0.019).
Conclusions:
The occurrence of peripapillary tessellated fundus is more than 30% in 3-6 year old preschool children. Tessellated fundus can also occur in non-myopic children, and is related to the length of axial length and large radius of corneal curvature.
