What Is Reis-B?cklers Dystrophy?

Reis B?cklers dystrophy is a rare inherited corneal dystrophy that primarily affects Bowman layer and the superficial stroma. Abnormal deposits replace the normal tissue in this zone, leading to recurrent corneal erosions and progressive surface irregularity. Children often present with painful episodes when the epithelial surface breaks down. Over time, central corneal opacities can blur vision and cause glare. The condition usually affects both eyes and follows an autosomal dominant pattern.

Clinical Features and Course

Early in life, patients experience episodes of sudden eye pain, tearing, and light sensitivity due to recurrent erosions. Between attacks, the cornea shows fine gray white opacities in the central region that gradually coalesce. As the dystrophy progresses, the surface becomes more irregular, and visual acuity declines. The epithelium may appear slightly elevated over the deposits. Peripheral cornea is often clearer than the center.

Genetics and Pathology

Reis B?cklers dystrophy is linked to mutations in the TGFBI gene, which also underlies several other anterior corneal dystrophies. Histologic studies show replacement of Bowman layer by a fibrous or granular material that extends into the superficial stroma. The abnormal matrix disrupts normal epithelial adhesion and smoothness. Family history often reveals other affected relatives with similar symptoms or prior corneal surgery. Genetic counseling can help families understand inheritance patterns.

Diagnosis and Differential

Diagnosis is based on characteristic clinical appearance, recurrent erosion history, and often supportive imaging. In vivo confocal microscopy and optical coherence tomography can highlight anterior corneal changes and the depth of deposits. The dystrophy must be distinguished from granular, lattice, and Thiel Behnke dystrophies, which have overlapping features. Genetic testing for TGFBI mutations can confirm the diagnosis in uncertain cases. Corneal specialists may review family members to clarify the pattern.

Management and Prognosis

Management focuses on reducing erosion episodes and improving optical quality. Lubricating drops and ointments, hypertonic saline, and bandage contact lenses are used for surface protection. For persistent erosions, anterior stromal puncture or phototherapeutic keratectomy can help by improving epithelial adhesion. In advanced cases with significant scarring, superficial keratectomy or lamellar keratoplasty is considered. Vision often improves after surface procedures, but recurrence on grafts or residual cornea can occur, so long term follow up is needed.

FAQs About Reis B?cklers Dystrophy

Is this dystrophy present at birth?

The genetic change is present from birth, but symptoms often appear in early childhood rather than in newborns.

Will both eyes be affected the same way?

Both eyes are usually involved, but severity can differ between them.

Can glasses fix the vision problems from this dystrophy?

Glasses can correct refractive error, but they cannot remove corneal opacities or irregularity.

Does corneal transplantation cure Reis B?cklers dystrophy?

Transplant or surface laser procedures can improve vision, but dystrophic changes can recur over time.
