Excessive hypermetropia: review and case report documented by echography
Annals of Ophthalmology
|January 1, 1982
Summary
This report details an 11-year-old boy with extreme hypermetropia (+22.0D) and a short axial length (14.8mm). This rare case, termed posterior microphthalmos, presents unique ocular dimensions and associated findings.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Ocular Anatomy
Background:
- Hypermetropia, or farsightedness, is a refractive error where the eye focuses images in front of the retina.
- Extreme hypermetropia is rare, particularly in pediatric cases, and often associated with specific ocular structural variations.
Observation:
- An 11-year-old boy presented with severe hypermetropia (+22.0 diopters).
- Ocular measurements revealed an axial length of 14.8 mm, significantly shorter than typical.
- Anterior segment dimensions were within normal limits, while vitreous length was reduced.
Findings:
- The condition was diagnosed as posterior microphthalmos without microcornea, highlighting a rare globe shape variation.
- Associated findings included pseudopapilledema and choroidal folds.
- Echographic measurements provided detailed dimensional analysis compared to adult emmetropic eyes.
Implications:
- This case expands understanding of extreme refractive errors and ocular development.
- The findings contribute to the literature on rare pediatric ocular conditions.
- Further research into the etiology and management of posterior microphthalmos is warranted.
