Axenfeld-Rieger spectrum is a range of anterior segment dysgenesis (ASD) phenotypes often related to heterozygous pathogenic variants in the ocular transcription factor genes or . Microcornea with myopic chorioretinal atrophy, a less common ASD, is distinct, recognizable, and secondary to biallelic pathogenic variants in the metalloproteinase gene . This report describes the case of a boy with -related ASD that was mistaken for Axenfeld-Rieger syndrome and highlights distinguishing features.

A 31-year-old male patient presented with the complaint of progressive vision loss in his left eye. Slit-lamp examination showed posterior embryotoxon, iris hypoplasia, and iridocorneal adhesion in both eyes, corectopia in the right, and peripheral inferior thinning and ectasia in the left eye. Corneal topography showed slightly asymmetric bowtie pattern in the right eye and crab-claw pattern in the left eye.

The phenotype of lens-ablated Mexican tetra (Astyanax mexicanus) compared to wild-type surface fish has been described and includes, among other effects, eye degeneration, changes in tooth number and cranial bone changes. Here, we investigate the spatiotemporal expression patterns of several key genes involved in the development of these structures. Specifically, we show that the expression of pitx2, bmp4 and shh is altered in the eye, oral jaw, nasal pit and forebrain in these lens-ablated fish.
