Presence of Fusion in Albinism after Strabismus Surgery Augmented with Botulinum Toxin (Type A) Injection
Case 2 was a 16-year-old boy with refraction in his right and left eye of +3.5 / -1.75 × 20° and +3.25 / -2.0 × 155° and a BCVA 2 / 10 and 3 / 10, respectively. He had 50Δ left exotropia and no fusion. He underwent 9 mm bilateral lateral rectus recession, augmented with intraoperative bilateral 12.5 U BTA (Dysport) injection, with no complications. On week 2 and month 1 follow-ups, he had 10Δ left esotropia which decreased to 6Δ left exotropia from the 4th month postoperative follow-up onwards; fusion in the Bagolini test was also observed at 4 months after surgery ().
