ABSTRACT

ABSTRACT: Introduction/Objective: Although different ophthalmological complications have been reported after in vitro fertilization, up to now there is no data available concerning strabismus. We present 7 patients with different types of strabismus and the pathogenesis will be discussed. Materials and methods: Patients 1 and 2 had Bilateral Duane Syndrome. Patient n° 3 had an Infantile Esotropia, Patients 4 trough 6 had acquired esotropia and patient n° 7 had an intermittent exotropia. Results: Multiple factors have been described as possible pathogenic factors in other ocular or systemic complications as: genetic (due to manipulation, to ovarian stimulation or to pathologic oocytes), vascular (abortion menace), the use of progesterone and antiabortive products and children of very low weight at birth (multiple deliveries, prematurity, mother age at pregnancy). Conclusions: Strabismus may appear after in vitro fertilization. Although different mechanisms may be the cause, we do not think our cases were due to the technique it self, but rather to the complicated characteristics of the women, who went through in vitro fertilization or to the multiple deliveries.
