RISPOSTE
- What is your diagnosis?
Answer: Reis-Bucklers' superficial corneal dystrophy, also known as
the superficial variant of granular dystrophy.
- What are the symptoms?
Answer: Frequent recurrent corneal epithelial erosion leading to
marked visual loss.
- What is the usual presentation for this condition?
Answer: The disease is diagnosed in the first years of life,
symptoms become prominent in the first decade, leading to progressing to
scarring and visual loss in the second, third, and fourth decades.
- What is the pathophysiology of this condition?
Answer: Disruption and loss of Bowman's membrane with replacement
by fiberous scar tissue resulting in superficial corneal opacification.
- What is the inheritance pattern of this condition?
Answer: Autosomal dominant.
- What treatment would you recommend?
Answer: In the early stages of Reis-Bucklers' dystrophy treatment
focuses on factors which control recurrent erosive episodes. These
modalities include copious lubrication, patching, or bandage contact
lenses. When visual acuity is limited by superficial scarring, excimer
phototherapeutic keratectomy is the initial treatment of choice.
- Does this condition recur?
Answer: Yes, Reis-Bucklers' dystrophy recurs after excimer
phototherapeutic keratectomy or corneal transplant.
