Axial length and refractive error in X-linked retinoschisis

PURPOSE: To examine the relationship between axial length and refractive er ror in patients with X-Iinked retinoschisis. DESIGN: To determine whether the hypermetropia frequently found in patients with X-linked retinoschisis is axial hypermetropia. METHODS: The axial length and refractive error were measured in 29 right ey es of 29 patients. The patients were divided into two groups: a juvenile gr oup with ages <13 years (12 eyes) and an adult group with ages <greater tha n or equal to>13 years (17 eyes). The axial length of the right eye of 30 a dult men without eye diseases whose refractive error ranged from +/- 1.0 di opter served as controls. RESULTS: Ln the adult patient group, the refractive error was significantly more hypermetropic and the axial length was significantly shorter than was the normal adult group (P < .001). CONCLUSION: These results strongly suggest that the hypermetropia in patien ts with X-linked retinoschisis is axial hypermetropia, (Am J Ophthalmol 200 1;131: 812-814, (C) 2001 by Elsevier Science Inc.
