Background: Excimer laser-assisted phototherapeutic keratectomy (PTK) has become established as the gold standard in treatment of epithelial basement membrane dystrophy (EBMD), commonly also known as map-dot-fingerprint dystrophy (MDF). At the Department of Ophthalmology, Saarland University Medical Center in Homburg/Saar, systems from Zeiss Meditec and Schwind have been used. The outcomes of both were compared in this study.

Hospital Clínico Universitario de Valencia, Valencia, Spain.

Introduction: A case of dual corneal involvement due to Fuchs endothelial corneal dystrophy and epithelial basement membrane corneal dystrophy in a patient with Steinert's myotonic dystrophy type 1 is described, and a literature review on the triple association is made.

Case Description: A 52-year-old male diagnosed with myotonic dystrophy type 1 presented due to progressive bilateral vision loss during the past year.

Department of Ophthalmology, Mayo Clinic, Jacksonville, FL 32224, USA,

Purpose: To comprehensively review the literature regarding recurrent corneal erosion (RCE) and to present treatment options and recommendations for management.

Overview: RCE usually presents with sharp, unilateral pain upon awakening, in an eye with an underlying basement membrane dystrophy, prior ocular trauma, stromal dystrophy or degeneration, or prior surgery for refractive errors, cataracts, or corneal transplantation. Making the correct diagnosis requires a careful slit-lamp examination of both eyes coupled with a high degree of suspicion. Read More

Dev Ophthalmol 2011 26;48:116-153. Epub 2011 Apr 26.

Corneal dystrophies typically result in a gradual bilateral loss of vision in a primary 'white eye' - often in conjunction with epithelial defects in later stages. Treatment of corneal dystrophies needs to be stage-related. To ensure a stage-related therapeutic approach, an adequate classification based on clinical, histopathological and genetic knowledge is indispensable. Read More

Department of Ophthalmology, Linköping University Hospital, Linköping, Sweden.

Purpose: To examine the role of Bowman's layer (BL) on the nature of anterior corneal regeneration after excimer laser phototherapeutic keratectomy (PTK).

Methods: A cohort of 13 patients underwent PTK to remove either 7 mum of BL for treatment of primary recurrent corneal erosions (RCE; six patients) or complete BL removal (15-mum ablation) to treat RCE or poor vision secondary to map-dot-fingerprint (MDF) dystrophy (seven patients). Clinical examinations and laser-scanning in vivo confocal microscopy (IVCM) were conducted before surgery and at a mean of 4 and 8 months after surgery. Read More

Epithelial basement membrane corneal dystrophy (EBMD), also known as Cogan microcystic epithelial dystrophy or map-dot-fingerprint dystrophy, is a common bilateral epithelial dystrophy. Usually, this disease is not considered to be inherited although several families with autosomal dominant inheritance have been described. We report the analysis of two families with an autosomal dominant pattern of inheritance as well as the analysis of single affected individuals; we identified two different point mutations in the TGFBI/BIGH3 genes, genes known to be associated with other corneal dystrophies.

Acta Ophthalmol Scand 2003 Feb;81(1):19-32

Department of Ophthalmology, University Hospital, SE-581 85 Linköping, Sweden.

Background: Phototherapeutic keratectomy (PTK) has been employed as a surgical tool to treat corneal disease for more than 10 years. The laser has made it possible to remove superficial corneal opacities and thereby restore vision. The 193 nm ultraviolet light separates molecules and splits molecules in biological tissue, thereby ablating it. Read More

Cornea 2001 Apr;20(3):309-16

Department of Surgery, Burns & Allen Research Institute, Cedars-Sinai Medical Center, University of California at Los Angeles Medical School Affiliate, 90048, USA.

Purpose: Activated myofibroblasts and macrophages are often found in corneal wound models. The current study was performed to determine whether human diseased corneas that had active tissue remodeling and enzyme activities also possessed myofibroblasts, macrophages, major histocompatibility complex class II cells, and/or CD-68-positive cells.

Methods: Normal, keratoconus, keratoconus with hydrops, bullous keratopathy, map-dot-fingerprint dystrophy, failed grafts, and acid burn/neovascularized corneas were collected, frozen in OCT, sectioned, and stained with antibodies to alpha smooth muscle actin (myofibroblast marker), CD14 (macrophage marker), CD68 (lysosomal membrane marker), and HLA-DR (major histocompatibility complex class II cells).

Purpose: To evaluate the excimer laser as a surgical instrument to treat map-dot-fingerprint (MDF) dystrophies.

Methods: Thirty eyes (24 patients) with MDF dystrophy were treated with phototherapeutic keratectomy (PTK). The treatment goal was either to improve vision (24 eyes) or to heal recurrent corneal erosions or both (10 eyes). Read More

J Refract Surg 1998 Mar-Apr;14(2):129-35

St. Erik Eye Hospital and Karolinska Institutet, Stockholm, Sweden.

Purpose: To evaluate the excimer laser as a surgical instrument for treatment of corneal dystrophies.

Methods: Excimer laser photoablation was performed with the Summit UV 200 and VISX 20/20 excimer lasers on 30 eyes of 21 patients with different types of corneal dystrophies; phototherapeutic keratectomy (PTK) on 28 eyes (20 patients) and photorefractive keratectomy (PRK) on two eyes (one patient). The treatment goals were to improve visual acuity (26 eyes of 18 patients), heal recurrent corneal erosions (eight eyes of five patients), and treat fluctuating refraction and visual acuity (three eyes of two patients).

A series of recurrent corneal erosions secondary to map-dot-fingerprint dystrophy is presented. Erosions were closely related to the Hudson-Stahli line, and this may be a factor in pathogenesis. Traumatic abrasions did not demonstrate such localisation, evidence that trauma is not a primary cause. Read More

Can J Ophthalmol 1984 Oct;19(6):266-8

Irregular astigmatism, the clinical manifestation of corneal warpage, was evaluated as a cause of decreased visual acuity in 24 patients with anterior membrane dystrophy (map-dot-fingerprint type). Qualitative ophthalmometry demonstrated corneal warpage in 20 of the patients. The best corrected visual acuity was improved with contact lenses over that achieved with spectacles in 14 of the 20.

Ann Ophthalmol 1984 Jun;16(6):567, 570-1

A scalloped line of tear film thinning (corneal valance), running horizontally across the top third of the cornea, was readily seen with slit lamp, fluorescein, and blue filter in 25 patients. Careful retrospective examination of these patients revealed barely discernible map and fingerprint lines corresponding to the areas of tear film irregularity. A corneascope photograph suggests that the tear film thinning in corneal valance is caused by localized elevations of the epithelial surface. Read More

We have observed the following complications with radial keratotomy which require further evaluation: missing the visual axis while marking the central cornea, regression of myopic flattening, epithelial defects, recurrent erosions, stromal overgrowth, Cogan's map-dot fingerprint corneal dystrophy with Moncreiff iron lines, blood in the incisions, vascular ingrowth, perforation of the anterior chamber, induction of astigmatic errors, epithelial ingrowth, glare complaints and decreased night vision, pain, fluctuating vision from morning to evening, overcorrection and unpredictable results, contact lens refitting difficulties, endothelial cell loss, and corneal scarring. We feel these complications require extensive further study before the relative safety and long-term efficacy of this experimental procedure may be determined. Read More

Ann Ophthalmol 1979 Mar;11(3):341-6

A 31-year-old woman with subepithelial corneal opacification and numerous clear round or oval areas of epithelial edema confined to the palpebral fissure underwent a penetrating keratoplasty. The clinical appearance was similar to that of a severe Meesmann or Stocker-Holt dystrophy. The prominent histopathologic features were thickening and excrescences of the epithelial basement membrane, intense basal cell edema, but no intraepithelial cysts. Read More
