Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this prospective study, entitled "The Long-Term Efficacy of Overminus Lens Therapy in Intermittent Exotropia",the investigators examined the long-term impact of overminus lenses on the management of intermittent exotropia (IXT), treatment effect after overminus treatment has been discontinued and also investigated if overminus lenses cause myopia in long-term.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Purpose: To evaluate the long-term impact of overminus lenses in intermittent exotropia (IXT), to determine if the treatment effect would persist after overminus minus lenses are discontinued and also to investigate if overminus lenses cause myopia.

Materials and Method: Sixty-five consecutive cases of IXT followed for at least 48 months were included. Patients with a history of previous surgery, ocular pathology, convergence insufficiency, severe myopia (\>-5.0 D), severe hyperopia (\>+5.0 D), moderate or severe amblyopia and poor compliance with spectacles were excluded. Data was collected including near stereoacuity, AC/A ratio, control of IXT measured with Newcastle Control Score (NCS) at baseline and in all follow-up visits. Baseline values without overminus threapy were compared with postintervention values at every visit.
