A rare genetic corneal disorder, posterior amorphous corneal dystrophy (PACD), presents with stromal opacities and flattening. This case reveals novel 12q21.33 chromosomal breakpoints associated with PACD, identified through advanced imaging and genetic analysis.
Area of Science:
- Ophthalmology
- Genetics
- Corneal Imaging
Background:
- Posterior amorphous corneal dystrophy (PACD) is a rare genetic disorder affecting corneal transparency.
- Characterized by posterior stromal opacification and corneal flattening, its genetic basis is not fully understood.
