Implementation of Diabetic Retinopathy Screening in Adult Patients With Type 2 Diabetes in a Primary Care Setting.

Diabetic retinopathy (DR) is a microvascular complication of type 2 diabetes and the leading cause of blindness globally. Although diabetes-related eye exams are widely recognized as an effective method for early detection of DR, which can help to prevent eventual vision loss, adherence to screening exams in the United States is suboptimal. This article describes a quality improvement project to increase DR screening rates and increase knowledge and awareness of DR in adults with type 2 diabetes in a primary care setting using mobile DR screening units. This project addressed gaps of care and demonstrated that primary care settings can increase access to DR screening through a patient-centered process and thereby help to prevent irreversible outcomes of DR and improve quality of life.

Acute Abducens Nerve Palsy in a Patient who Sustained Mechanical Trauma to the Orbit.

BACKGROUND: Abducens nerve (Cranial Nerve VI) innervates the lateral rectus (LR) muscle. Head trauma is one of the most common causes of abducens nerve palsy. Orbital and/or facial injuries could also affect the LR muscle directly or the orbital course of abducens nerve and lead to palsy. We present a case of a young man with multiple orbital fractures and an impingement of the LR muscle resulting in a complete loss of abduction. CASE REPORT: A 29-year-old male reported falling 15 feet. He presented with diplopia and had complete abduction deficit of the left eye. Orbital CT imaging revealed a bony spur from his left zygomatic bone impinging on the lateral rectus muscle. In view of -4 abduction deficit, he was operated upon to remove the bony spur. This led to a gradual, but complete recovery of his abduction. DISCUSSION: The abducens nerve has a tortuous course and as a result is commonly injured during head trauma, in particular due to its vulnerability as it passes into Dorello's canal, or its journey through the cavernous sinus. The case report highlights orbital causes such as direct muscle avulsion or injury to the orbital portion of the abducens nerve, as reasons for how LR weakness could be easily overlooked, unless specifically examined with high-resolution orbital imaging. CONCLUSION: Orbital mechanical causes can be overlooked in LR palsy. We emphasise the role of orbital imaging in any patient with abducens nerve or LR Palsy and reaffirm that not all cases are associated with an intracranial cause.
