Large-segment superior oblique tendon expanders in the management of severe congenital Brown syndrome.

Purpose: To report the effectiveness of large-segment superior oblique tendon expanders for severe congenital Brown syndrome.

Methods: Medical records of 12 consecutive patients with severe congenital Brown syndrome were evaluated retrospectively. All patients had a hypotropia > 20 prism diopters in primary position.

Restoration of binocular single vision after long-term fusion disruption.

Background: One of the most difficult situations faced by orthoptists and pediatric ophthalmologists is attempting to restore binocular single vision to a patient who has experienced a long-term disruption of fusion. Initial poor results with standard treatment modalities, including prisms and strabismus surgery, may lead to a diagnosis of intractable diplopia.

Methods: We examined, treated, and followed up 5 patients with strabismus after an extended period of monocular vision loss.
