Dermochondral corneal dystrophy (of François) has been reported rarely in the literature. It consists of a triad of findings characterised by the development of skin nodules, acquired deformities of the extremities, and a corneal dystrophy. The corneal dystrophy is central and superficial with whitish subepithelial opacities. We present two brothers who display previously unreported ocular find...

The term corneal dystrophy embraces a heterogenous group of bilateral genetically determined non-inflammatory corneal diseases that are restricted to the cornea. The designation is imprecise but remains in vogue because of its clinical value. Clinically, the corneal dystrophies can be divided into three groups based on the sole or predominant anatomical location of the abnormalities. Some affec...

Clinical Features (Fig. 1, overleaf) The condition appears to be asymptomatic and presents as a chance clinical finding. The corneal lesions are round, discrete dense opacities 0 5 mm. or less in diameter. They lie at the level of Bowman's membrane and usually extend just into the superficial stroma. The typical lesion has a striking white or creamy, rather porous-looking centre, and this is su...

PURPOSE This study aimed to evaluate the effectiveness of phototherapeutic keratectomy (PTK) as an alternative treatment to keratoplasty using the Pentacam to assess depth of dense opacities. METHODOLOGY PTK was performed in eleven eyes of ten patients with superficial corneal opacities after assessment by Scheimpflug images of the Pentacam for central corneal thickness (CCT) and opacity leve...

Forty cases of clear corneal grafts in 2 groups of patients who developed corneal opacities either before or after 5 years of age were investigated for the pattern of amblyopia and fixation. A severe irreversible form of amblyopia with eccentric fixation was observed in cases of unilateral corneal opacity when the anomaly occurred before the age of 5 years and corneal grafting was delayed until...

BACKGROUND Pre-Descemet corneal dystrophy (PDCD) is characterized by the presence of numerous, tiny, polymorphic opacities immediately anterior to Descemet membrane, which is a rare form of corneal stromal dystrophy and hard to be diagnosed. In vivo confocal microscopy (IVCM) is a useful tool to examine the minimal lesions of the cornea at the cellular level. In this article, we report a rare c...

BACKGROUND Peters anomaly is a rare developmental abnormality of the anterior segment of the eye and is one of the main causes of congenital corneal opacities. Typically, histopathology of Peters anomaly shows immature or absent Descemet's membrane and attenuated endothelial cells in the area of the corneal opacity, in addition to thinning or absence of Bowman's membrane and defects in the post...
