Clinical Analysis of Strabismus between Siblings

ABSTRACT

To investigate the clinical similarity between the siblings, we retrospectively studied the medical records of 64 patients, 32 pairs. 31 pairs showed the similar entity of strabismus between siblings. There was exotropia in 22 pairs, esotropia in 5 pairs, bilateral superior obliqre palsy in 2 pairs, exotropia, esotropia and Duane`s retraction syndrome in 1 pair. One was exotropia and the other was exotropia and Duane`s retraction syndrome in one pair. One pair was bilateral supperior obliqre palsy and esotropia and the other was right gypertropia and exotropia. The difference in the amount of deviation was less than 10 prism diopter in 23 pairs. There was no association between the strabismic siblings in refractive anomaly, amblyopia, and anisometropea. The surgical results were similar in 7 pairs of siblings among 8 pairs who underwent corrective operations.
