简要总结
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.
详细描述
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.

结局指标
主要结局
The long-term effect of overminus lenses in fusional capacity of patients with intermittent exotropia.
时间窗: 4 years
Overminus lenses were prescribed on the treatment of intermittent exotropia as the first choice. To investigate the effect of overminus lenses on treatment, progress in fusional capability of the patients evaluated with Newcastle control score system were investigated.
The long-term effect of overminus lenses on stereopsis of patients with intermittent exotropia.
时间窗: 4 years
Changes in stereopsis values (arcsec) evaluated with TNO test were observed.
The long-term effect of prescribing overminus lenses on refractive changes.
时间窗: 4 years
Refractive data of the patients in terms of dioptri were measured with autorefractometer during the long-term follow-up period to observe presence of any myopic shift.
