Bilateral inferotemporal retinal dialysis in siblings

Purpose: Two siblings, a brother and a sister, had extensive retinal dialysis in both eyes and in similar locations. One patient was asymptomatic and his bilateral dialysis was noted on routine examination for refraction. His sister noted progressive blurring in one eye and was found to have bilateral dialysis. Both children wore low myopic correction. The female presented at age 11 years and her brother presented at age 12 years, 5 years later. Methods: Both children underwent bilateral scleral buckling procedures with several months between the procedures on each eye. Results: Both retinae of both children have remained attached with stabilization in visual acuity in 3 eyes at 6/9 and improvement in one eye from Hand Movements to 6/24 (this was the only eye in which the macula was detached). Conclusions: Retinal detachment associated with inferotemporal dialysis occurs in only 10% of all retinal detachments. We report one family in which bilateral inferotemporal dialysis are found in siblings indicating a possible genetic predisposition to this condition in some families.
