Abstract
Aim: To describe the ease of a 21-year-old woman who presented with a constant esotropia with diplopia following the onset of anorexia nervosa, in whom the control of her strabismus and diplopia improved as body weight was regained.
Method: The orthoptic findings are presented and the outcome of treatment with botulinum toxin injection is reported.
Results: Botulinum toxin injection reduced the angle of deviation from 50Δ base-out (BO) for distance and 45Δ BO for near, to 30Δ BO for distance and 25Δ BO for near. After the injection the patient reported a marked improvement in symptoms and experienced diplopia only when tired. Over time and in conjunction with weight gain the deviation was controlled to a microtropia with an associated latent component with demonstrable anomalous binocular vision.
Conclusion: This case shows the possible effects of anorexia on the balance of the oculomotor system, with the onset of a convergent squint at a time of severe weight loss. Botulinum toxin injection under local anaesthetic may be the wisest and least invasive therapeutic choice in these patients, thereby avoiding a surgical procedure under general anaesthesia, which may be unsuitable in cases of anorexia.
