What is posterior polymorphous dystrophy?
What is posterior polymorphous dystrophy?
Posterior Polymorphous Corneal Dystrophy (PPMD, PPCD), also known as Schlichting dystrophy, is an autosomal dominant disorder of the corneal endothelium and Descemet’s membrane, producing a wide variability in clinical presentation.
What is POG dystrophy?
First described by Koeppe, posterior polymorphous corneal dystrophy (PPMD) is a dominantly inherited condition characterized by particular alterations of the Descemet membrane and the corneal endothelium. Typically, the corneal changes are either slowly progressive or nonprogressive.
Can you get Lasik with posterior polymorphous dystrophy?
LASIK can be a safe procedure in patients with posterior polymorphous dystrophy and proper selection criteria.
What is polymorphous dystrophy?
Posterior polymorphous corneal dystrophy (PPMD, PPCD) is a rare, bilateral, autosomal dominant inherited corneal dystrophy. The corneal abnormality in PPMD occurs at the level of Descemet’s membrane and endothelium, and rarely will result in corneal edema or elevated intraocular pressure.
What is posterior Embryotoxon?
Posterior embryotoxon (PE) is a corneal abnormality that is visible with slit-lamp biomicroscopy as a thin grey-white, arcuate ridge on the inner surface of the cornea, adjacent to the limbus. It is an anteriorly displaced Schwalbes line, the junction of Descemets membrane and the uveal trabecular meshwork.
What is granular corneal dystrophy?
Granular corneal dystrophy is the slow forming of deposits in the middle layer of the cornea, which can lead to vision impairment and discomfort. Symptoms include decreased vision and eye discomfort or pain.
Can you get Lasik with corneal dystrophy?
PRK and laser-assisted in situ keratomileusis (LASIK) have been associated with exacerbation of combined granular-lattice corneal dystrophy. LASIK and PRK appear to be safe in mild forms of posterior polymorphous corneal dystrophy, whereas LASIK should be avoided in Fuchs dystrophy.
What is PPD of the eyes?
Posterior polymorphous dystrophy (PPD) is a bilateral, inherited condition affecting the corneal endothelium and Descemet’s membrane. The common features of iridocorneal endothelial syndrome (ICE) and PPD have been reported to co-exist.
What causes posterior Embryotoxon?
Posterior embryotoxon is caused by a gene mutation that is passed down in families.
