During a 5-month period, four patients developed contracture of the inferior rectus muscle following local anesthesia for cataract surgery in the practice of one ophthalmologist. Two anesthesiologists administered retrobulbar anesthesia. All patients had persistent vertical diplopia caused by a large hypotropia of the operated eye. Forced duction testing revealed marked restriction to elevation of the eye. In two patients, MRI demonstrated segmental thickening of the inferior rectus muscle, just posterior to the globe. All patients had normal thyroid function tests. No patient had a previous history of strabismus. Three of the four have had strabismus surgery consisting of recession of the markedly restricted inferior rectus muscle on an adjustable suture. These three patients have regained fusion and are now asymptomatic.

We describe a case of disintegration of the inferior rectus muscle during routine strabismus surgery for restrictive hypotropia after cataract surgery. We used this surgical approach to repair the complete infraduction deficit incurred from the injury.

We present yet another case of apparent inferior rectus paralysis following retrobulbar anesthesia for cataract surgery. He initially had a typical course but, unusually, after developing hypotropia and presumed contracture, went on to spontaneously recover. We are unaware of any other such case described in the literature. Methods to enhance this more desirable course are considered.

The purpose of this study was to demonstrate two cases of vertical diplopia after cataract surgery and to discuss the mechanism and types of strabismus caused by the local anesthesia with retrobulbar injection. Two cases of vertical diplopia after cataract surgeries were reported. They were operated by the same surgeon and both happened to the left eye and both presented with marked left hypotropia. The clinical findings consisted of overacting left inferior rectus (LIR) in case 1 and mixed overacting and restrictive LIR in case 2. The diplopia and left hypotropia were eliminated after muscle operation. Retrobulbar injection is a basic technique in ophthalmic practice. Although it is generally safe, complications do happen in certain cases including diplopia and strabismus. Ophthalmologists should know about the orbital anatomy and learn to prevent any accidental insult to extraocular muscles.

A 56-year-old woman with pseudophakia and glaucoma was referred because of left eye hypotropia and esotropia noted following superotemporal Ahmed glaucoma valve implantation in that eye. Examination suggested left heavy eye syndrome, and it was confirmed the patient had high axial myopia before her cataract surgeries. Both nasal displacement of the left superior rectus muscle and inferior displacement of the left lateral rectus muscle were noted intraoperatively. Removal of the glaucoma drainage device, posterior loop myopexy of the superior rectus muscle to the lateral rectus muscle, and implantation of a new glaucoma drainage device inferonasally improved the strabismus.
