Axial length and refractive error in X-linked retinoschisis.

PURPOSE: To examine the relationship between axial length and refractive error in patients with X-linked 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 eyes of 29 patients. The patients were divided into two groups: a juvenile group with ages <13 years (12 eyes) and an adult group with ages > or =13 years (17 eyes). The axial length of the right eye of 30 adult men without eye diseases whose refractive error ranged from +/- 1.0 diopter served as controls.

RESULTS

In 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 patients with X-linked retinoschisis is axial hypermetropia.
