Manejo del estrabismo asociado al glaucoma de la infancia: serie de casos

Abstract

Objective To evaluate the different modalities of treatment of the strabismus related to infantile glaucoma, its complications, and results. Methods The clinical history of 7 patients with infantile glaucoma which required strabismus surgical treatment were analyzed. Age at onset of glaucoma, type of glaucoma, glaucoma surgeries, type of strabismus, strabismus surgical treatment and postoperative results were studied. Results Four patients required strabismus surgery, two were treated with botulinum toxin and one required both. Primary congenital glaucoma was the most common (71,42%), 14,28% had an anterior segment dysgenesis and 14,28% had secondary glaucoma. Regarding strabismus, 4 patients had exotropia and 3 had esotropia. The main difficulty involved the management of the conjunctiva and the filtering blebs. Conclusion Strabismus is a frequent complication in infantile glaucoma. The management of these patients should be individualized. In our case series, treatment of strabismus improved eye alignment. Surgery should be the mainstay of treatment while preserving the conjunctiva and interfere the less with glaucoma surgeries. Botulinum toxin is a reasonable option when conservative treatment is needed.
