[Fuchs heterochromic iridocyclitis and pellucid corneal marginal degeneration: a co-incidence or a developmental defect?]

ABSTRACT

To report a patient with Fuchs' heterochromic iridocyclitis and pellucid corneal marginal degeneration. A 37-year-old woman referred to Poostchi Eye Clinic, Shiraz, Iran with complaint of low vision in both eyes especially in the left side since many years ago. On ophthalmologic examination, best-corrected visual acuity was 20/50 in right eye with refraction of -6.50-7.5@90 and 20/80 in left eye with refraction of -8.50-11.00x90. Slitlamp examination revealed inferior thinning of cornea in both eyes and diffuse keratic precipitates on corneal endothelium, 1+ cell and flare in the anterior chamber and posterior subcapsular cataract in left eye. There was a moderate iris hetererchromia between the eyes which beside other findings was suggestive of Fuchs' heterochromic iridocyclitis. Corneal topography was in favor of pellucid marginal degeneration. To our knowledge this is the first case of pellucid marginal degeneration associated with Fuchs' heterochromic iridocyclitis in the literature. This may be a co-incidence or might have occurred due to a defect in embryonic ocular development
