ABSTRACT

Three eyes of three patients with grave alkali burns (n-2) and with Coats disease after retinal detachment surgery (n-1). All of the cases presented a total limbal stem cells deficiency. Cases 1 and 2 had an burning evolution of 2 years and 8 months respectively, and the case 3 an evolution of 8 months before surgery. All patients underwent the same operation: Peritomy 360º, keratectomy of corneal fibrovascular membrane, limbo-conjuntival autograft from the healthy fellow eye and implantation of amniotic membrane. Case number 1 with preoperatory visual acuity of light perception and projection improved to 0,3 his visual acuity after 12 months and with +1,50-0,50 x 90 a visual acuity 0,9 after 12 years. Case 2 with preoperatory visual acuity of counter finger at 20 centimeters improved his visual acuity 0,6 after two years, and case 3 with preoperatory visual acuity of light perception improved to 0,05 (20/500). In all cases, limbal-conjunctival autograft of the healthy fellow eye with amniotic membrane transplantation resulted an excellent option for improving visual acuity and laborer rehabilitation in cases 1 and 2 (achieving case 1 excellent visual acuity). Case 3 had a total corneal epithelization and an evident improvement in corneal transparency, but visual acuity had a little improvement due to base disease.
