Abstract Details

Purpose:

We describe two cases of posterior polychromatic corneal dystrophy, a pre-Descemet dystrophy, poorly described in world literature, characterized by diffuse polychromatic points on the posterior corneal stroma, without visual impairment.

Setting:

IOBH (Eye Institute of Belo Horizonte), Minas Gerais, Brazil.

Methods:

Two women, 30 years old and 23 years old respectively, unrelated, without comorbidities and without familial history of ocular diseases, underwent complete ophthalmologic examination, corneal topography, pachymetry, noncontact specular microscopy and anterior segment optical coherence tomography (OCT) in both eyes.

Results:

At biomicroscopy, both patients presented transparent corneas with fine opacities, uniforms, polychromatic and diffusely distributed on the posterior corneal stroma bilaterally. Visual acuity and remaining ophthalmological examination were normal in both patients. Corneal topography and pachymetry were normal bilaterally. Noncontact specular microscopy showed normal cellular density, without significant polymegathism and/or pleomorphism and numerous bright spots corresponding to the posterior stromal opacities in both eyes of both patients. Anterior segment OCT showed hyperreflective dots on the posterior corneal stroma, without other changes, in both patients. Patients were instructed to maintain periodic ophthalmological follow-up.

Conclusions:

Pre-Descemet dystrophies are not yet a well-defined clinical entity and do not have a clarified pattern of genetic inheritance. Although it appears to do not require treatment over time, it is important to recognize this dystrophy, avoiding confusion with other clinical conditions that require specific care and treatment. Studies that elucidate the responsible gene for this condition and its form of genetic inheritance are still needed in order to polychromatic corneal dystrophy recognition as a well-defined corneal dystrophy.
