Abstract

OBJECTIVE: Functional outcomes following facial and ocular trauma are time-sensitive and require prompt evaluation to minimise long-term vision loss, yet few studies have systematically evaluated disparities in the management of these cases. This study investigates whether a patient's race/ethnicity, primary language, insurance status, gender or age affects receipt of ophthalmology consultation for facial trauma.METHODS AND ANALYSIS: This study was a retrospective cohort analysis of patients from the Elmhurst City Hospital Trauma Registry in Queens, New York who were seen for facial trauma including open globe injuries and orbital fractures between January 2014 and May 2016.RESULTS: Of the 264 patients included, 43% reported as Hispanic, 23% white, 11% Asian, 8% black and 15% other/unknown. After controlling for confounding variables by multivariable logistic regression, neither race/ethnicity, gender, nor primary language were significantly associated with the likelihood of receiving an ophthalmology consult. However, patients with private insurance had 2.57 times greater odds of receiving an ophthalmology consultation than those with Medicaid or state corrections insurance (95%CI 1.37 to 4.95). As age increased, the likelihood of receiving an ophthalmology consultation decreased (p=0.009); patients 60 years of age and older had one-third the odds of ophthalmology consultation as younger patients (OR 0.33; 95%CI 0.16 to 0.68).CONCLUSIONS: This study highlights that lack of ophthalmology consultation in patients with facial trauma is linked to age and underinsurance. Extra attention must be paid during primary assessments to ensure elderly patients and those with public insurance have equitable access to timely and appropriate care for facial trauma.

Abstract

The cornea is critical for vision, and corneal healing after trauma is fundamental in maintaining its transparency and function. Through the study of corneal injury models, researchers aim to enhance their understanding of how the cornea heals and develop strategies to prevent and manage corneal opacities. Chemical injury is one of the most popular injury models that has extensively been studied on mice. Most previous investigators have used a flat paper soaked in sodium hydroxide to induce corneal injury. However, inducing corneal and limbal injury using flat filter paper is unreliable, since the mouse cornea is highly curved. Here, we present a new instrument, a modified biopsy punch, that enables the researchers to create a well-circumscribed, localized, and evenly distributed alkali injury to the murine cornea and limbus. This punch-trephine method enables researchers to induce an accurate and reproducible chemical burn to the entire murine cornea and limbus while leaving other structures, such as the eyelids, unaffected by the chemical. Moreover, this study introduces an enucleation technique that preserves the medial caruncle as a landmark for identifying the nasal side of the globe. The bulbar and palpebral conjunctiva, and lacrimal gland are also kept intact using this technique. Ophthalmologic examinations were performed via slit lamp biomicroscope and fluorescein staining on days 0, 1, 2, 6, 8, and 14 post-injury. Clinical, histological, and immunohistochemical findings confirmed limbal stem cell deficiency and ocular surface regeneration failure in all experimental mice. The presented alkali corneal injury model is ideal for studying limbal stem cell deficiency, corneal inflammation, and fibrosis. This method is also suitable for investigating pre-clinical and clinical efficacies of topical ophthalmologic medications on the murine corneal surface.

Abstract

To characterize the epidemiology, associated complications, and risk factors of orbital floor fractures in a nationwide longitudinal health insurance database.Claims data from a million randomly selected registered residents from the Taiwan National Health Insurance Research Database were analyzed between 2001 and 2011 as part of a retrospective cohort review. Patients were identified using the International Classification of Disease-9 diagnosis codes for orbital floor fracture (closed: 802.6; open: 802.7). The cases were categorized as surgical or nonsurgical based on the procedure codes and compared statistically.From 2001 to 2011, 663 patients were diagnosed with orbital floor fractures out of a total population at risk of 9,836,431 person-years (average incidence: 6.78 persons/100,000/year) with overall increasing incidence. Surgical treatments were performed in 213 (32%) patients. Patients who received surgical treatment were younger than those who did not (mean age 25.3 ± 13.6 years vs. 34.2 ± 18.6 years, P < 0.001). The diagnosis with diplopia was a significantly associated factor for surgical treatment (2.2% in nonsurgery group vs. 6.6% in surgery group, P = 0.007). Male gender (adjusted hazard ratios [aHR] = 2.1, 95% confidence interval [CI]: 1.79-2.49) and low monthly income (aHR = 1.76, 95% CI: 1.16-2.67) were the risk factors for orbital floor fracture.The incidence of orbital floor fractures increased in the Taiwanese population between 2001 and 2011. Men and low income patients were at increased risk of orbital floor fracture. More research is necessary to clarify what factors are driving the escalating incidence of orbital fractures in this national population.
