purpose: to study the effect of phototherapeutic keratectomy (ptk) in the treatment of various superficial corneal pathologies. methods: we performed a nonrandomized, prospective study on patients who presented with superficial corneal disease and/or poor vision. fifty eyes were included recurrent corneal erosion (rce): 25 eyes, salzmann’s nodular degeneration: 9 eyes, spheroidal degeneration: ...

Classification of trachoma by site rather than density of opacities is better related to visual prognosis and helps in selection for graft surgery. The cases are divided into 3 groups: peripheral corneal opacities, central corneal opacities, and diffuse corneal opacities (ground-glass cornea). A central lesion has the poorest prognosis, especially in children.

PURPOSE To describe etiologies and clinical characteristics of corneal opacities leading patients to seek cosmetic treatments. METHODS The medical records of 401 patients who presented for cosmetic improvement in corneal opacities between May 2004 and July 2007 were retrospectively reviewed. The following parameters were analyzed: age, gender, cause of corneal opacity, time course of the corn...

An infant with trisomy 8 mosaicism had bilateral corneal opacities and multiple systemic anomalies. A review of the literature suggests that corneal opacities are a prominent feature of the syndrome and may have substantial clinical and diagnostic importance.

Spontaneously occurring anterior corneal opacities were present in related, juvenile American Dutch belted rabbits. Slit lamp biomicroscopy revealed focal opacities of epithelium, basement membrane, and subepithelial corneal stroma. Lesions were characterized histologically by thin and disorganized surface epithelium, thickened and intensely staining epithelial basement membrane, fimbriated and...

PURPOSE We report a case of Terrien's marginal degeneration (TMD) with a unilaterally typical narrow band of peripheral corneal stroma thinning, accompanied by the presence of an unusual network of opacities diffusing throughout the anterior stroma layers. CASE REPORT A 43-year-old woman presented with superior nasal peripheral corneal thinning and an unusual network of polygonal stromal opac...
