What is Reis Buckler corneal dystrophy?

Reis-Bücklers corneal dystrophy (RBCD) is an inherited corneal disorder that was first described by Reis1 in 1917 and later by Bücklers2 in 1949. Affected individuals have an onset early in life and have frequently recurring, painful corneal erosions, superficial corneal opacities, and significant visual impairment.

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 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 is map dot dystrophy?

Map-dot-fingerprint-dystrophy occurs when the bottom, or basement layer, of cells in the cornea thickens or become folded. The folds create grey shapes that look like continents on a map, as well as opaque dots. In some cases, these folds may form concentrically, and look like fingerprints.

What is Cogan’s dystrophy?

Cogan’s Dystrophy is a disease that affects the cornea. It is commonly called Map-Dot-Fingerprint Dystrophy because of microscopic dot and fingerprint-like patterns that form within the layers of the cornea. The cornea is comprised of five layers. Cogan’s affects the superficial cornea layer called the epithelium.

What’s better LASIK or PRK?

LASIK takes a few days or less to see clearly while PRK takes about a month. The final results won’t differ between the two if the procedure is done properly by a licensed, experienced surgeon. Overall, PRK is considered to be safer and more effective in the long term because it doesn’t leave a flap in your cornea.

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.

Is map dot dystrophy painful?

Patients with map-dot-fingerprint dystrophy may be asymptomatic. Others experience painful recurrent erosions, decreased vision, or both.

Which is the most common corneal dystrophy?

LATTICE CORNEAL DYSTROPHY. Lattice corneal dystrophy (LCD) is the most common of the corneal epithelial-stromal dystrophies. It is typically an autosomal dominant, bilateral disease that typically presents toward the end of the first decade of life with symptoms of recurrent corneal erosions and decreased vision.

What kind of corneal dystrophy is posterior polymorphous?

Posterior Polymorphous Corneal Dystrophy (PPMD) 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 are the signs of corneal dystrophy ( PPMD )?

Usually bilateral, but sometimes asymmetric, diffuse corneal opacification on physical examination along with corneal edema and thickening are indicative of PPMD. Other corneal findings include endothelial vesicular changes, band lesions, opacities, and possibly a peripheral ring.

What do vesicle-like lesions look like in PPMD?

Figure 1: Vesicle-like lesions in PPMD. Vesicle-like lesions at the level of Descemet’s membrane and endothelium are the hallmark lesions of PPMD. They appear as transparent cystic lesions surrounded by gray halos and commonly occur in lines or clusters.

Is there a family history of corneal dystrophy?

No other known family history of eye disease or corneal dystrophies. Diffusely scattered, well-circumscribed areas of stromal haze localized to the posterior 1/3 of the stroma. Most measure about 0.5 mm in size with intervening clear spaces. No associated neovascularization. No epithelial breakdown or erosions. (Fig. 1)
