Strabismus is a disorder in which the eyes are incorrectly lined up with each other. Either eye is always or infrequently looking inward (esotropia) or outward (exotropia). A 19-year-old male patient came to the Ophthalmology Outpatient Department (OPD) with complaints of outward deviation of the left eye for five years. It was associated with a diminution of vision in the left eye for three years. The patient reported a history of a road traffic accident (RTA) five years ago before the development of deviation of the left eye. On examination, the Hirschberg test showed a corneal light reflex falling beyond the limbus. After obtaining due consent for anesthesia risk and medicine fitness, the patient underwent squint correction surgery (medial rectus resection) and was started on oral and topical antibiotics with a 15-day follow-up period. Postoperative orthophoria was achieved.

“…Sensory deficits resulting from the trauma (such as traumatic cataracts, visual field defects, traumatic optic neuropathy or a central loss of fusion) or preexisting conditions (such as amblyopia, suppression or anomalous correspondence from a childhood onset strabismus) may confound the results of standard motor testing. 1 …”

“…A severely limited eye may not be able to move into the primary position to take up fixation, and it is easy to underestimate traumatic strabismus. 1 In some patients measurement using Krimsky light reflex testing may be necessary. Both the primary and secondary deviations are important.…”

An approach to some aspects of strabismus from ocular and orbital trauma

Strabismus caused by ocular or orbital trauma can be the result of localized acute soft tissue swelling or may follow orbital fractures, partial or complete loss of extraocular muscle (EOM) and/or cranial nerve function, or damage to surrounding tissues causing mechanical restriction. The strabismus is frequently incomitant and can be difficult, if not impossible to completely correct. The resulting diplopia can affect the individual's ability to function at work, in sports and in common tasks of daily living like driving. The preoperative evaluation should include an assessment of the degree of limitation, muscle function and the condition of the surrounding tissue. In most cases, high resolution computed tomography and/or surface coil dynamic magnetic resonance imaging are required to determine the extent and nature of suspected bony or EOM injury, as well as muscle contractility. If the scan reveals an intact but paretic muscle or only minor muscle injury, surgical intervention is based on the degree of muscle recovery 6 months after the initial insult. If a rectus muscle has been lacerated, and the proximal stump is functional, retrieval should be attempted, either by a direct conjunctival approach if located anteriorly, or by an anterior medial orbitotomy if located deep in the orbit. If a damaged muscle cannot be found, recovered or repaired at any time, then muscle transposition should be considered. If multiple muscles are damaged or scar tissue is excessive, a tether procedure may be indicated. This paper will present an approach to some aspects of strabismus in this setting.

“…A detailed sensorimotor exam should be performed, with attention to versions, ductions, saccades, pursuit, vergence, and near reflex, along with alignment in multiple gaze positions with attention to primary and secondary deviations. 178 Forced duction and forced generation testing may help distinguish restriction from paresis of the extraocular muscles. 179 Double Maddox rod, Lancaster red-green, Hess screen, or synoptophore (especially if there is concern for disrupted central fusion) may also be helpful.…”

The Adult Strabismus PPP was then sent for review to additional internal and external groups and individuals in August 2019. All those returning comments were required to provide disclosure of relevant relationships with industry to have their comments considered. Members of the Pediatric Ophthalmology/Strabismus Preferred Practice Pattern Panel reviewed and discussed these comments and determined revisions to the document. The following organizations and individuals returned comments.
