  • Title: Evaluation of ocular changes secondary to blowout fractures.
    Author: Mazock JB, Schow SR, Triplett RG.
    Journal: J Oral Maxillofac Surg; 2004 Oct; 62(10):1298-302. PubMed ID: 15452819.
    Abstract:
    There has been extensive debate over the standard of care of orbital fractures. Entrapment, diplopia, and hypoglobus, with or without enophthalmos, are the most common clinical indications for surgical intervention. Evaluation of these injuries is often limited in the early postinjury period because of edema. In assessing the severity of the injury, the clinician often uses parameters such as changes in visual acuity, patient-reported diplopia, gross changes in globe position, and an evaluation of the extraocular muscles. Many of these parameters are only grossly assessed and therefore are not specifically documented and tracked. The decision to proceed with surgical intervention may be based only on these gross clinical findings. The purpose of this article is to present a reliable and repeatable method for evaluating the degree of diplopia and the globe position of the orbital trauma patient by describing the use of the double Maddox rod test (Wilson Ophthalmic, Mustang, OK) and Hertel exophthalmometer (Wilson Ophthalmic). These methods can provide sequential documentation of the progression of the injury and help better define the need for surgical intervention and to follow the postoperative course.
