Avellino (combined granular-lattice corneal) dystrophy
This case has been published in the Digital Journal of Ophthalmology.

A 35-year-old woman presented with a 6-month history of glare and painless diminution of vision in both eyes. On examination, her best-corrected visual acuity was 20/20 in the right eye and 20/60 in the left eye.

White “bread crumb” opacities with “moth-eaten” centers were observed in the superficial and mid-corneal stroma (A, B). These were interspersed with star-shaped, spiny, or icicle-shaped deposits as seen in anterior segment optical coherence tomography (C, D).

These features are consistent with Avellino dystrophy, also known as combined granular-lattice dystrophy, or granular corneal dystrophy, type 2 (GCD2). It is caused by a mutation in the TGFBI (transforming growth factor beta-induced) gene and is characterized by both amyloid and hyaline deposits in the corneal stroma.

Patients are treated with phototherapeutic keratectomy or with penetrating keratoplasty. Because this patient had good vision, only spectacle correction was advised, and she continued to be followed for disease progression.
