This study determined whether retinal degeneration during diabetes includes retinal neural cell apoptosis. Image analysis of retinal sections from streptozotocin (STZ) diabetic rats after 7.5 months of STZ diabetes identified 22% and 14% reductions in the thickness of the inner plexiform and inner nuclear layers, respectively ( P Ͻ 0.001). The number of surviving ganglion cells was also reduced by 10% compared to controls ( P Ͻ 0.001). In situ end labeling of DNA terminal dUTP nick end labeling (TUNEL) identified a 10-fold increase in the frequency of retinal apoptosis in wholemounted rat retinas after 1, 3, 6, and 12 months of diabetes ( P Ͻ 0.001, P Ͻ 0.001, P Ͻ 0.01, and P Ͻ 0.01, respectively).

The orbicularis oculi muscle fusion to the maxilla below the arcus marginalis defines the junction between the eyelid and the cheek, and it provides an anchor for the tear trough. The eyelid-cheek interface is significantly elevated with our surgical technique of fat repositioning in the supraperiosteal plane. Elevation of the orbicularis muscle edge may contribute to improved blepharoplasty results in treating the aging midface.

Anterior filler displacement is a potential complication of orbital volume augmentation with injectable calcium hydroxylapatite. Patients should be counseled regarding this possibility when considering options for the treatment of anophthalmic enophthalmos. A history of multiple prior orbital surgeries, with associated tissue disruption and scarring, may be a risk factor for filler displacement.

Evaluation and management of eye trauma is daunting to many practitioners. For general medical emergencies, the familiar ABCs mnemonic serves to both recompose the provider as well as provide a logical order for evaluation and action. We recently adapted an ABCs mnemonic to provide non-ophthalmologists with a familiar method for systematically evaluating and managing eye trauma. A = ACUITY. Visual acuity is the most importance piece of information in eye trauma. B = BEST exam of BOTH eyes. Starting with acuity, examination proceeds from the front to the rear of the eye. Examine the uninjured eye first. C = CONTIGUOUS STRUCTURES and CONTACT LENSES. Examine structures contiguous to the apparent injury. Inspect for contact lens wear. D = DRUGS, DIAGNOSTIC IMAGING, and the DON’TS. Start antibiotics, antiemetics, and analgesics. Administer tetanus. Obtain computerized tomography if available. Do not attempt ocular ultrasound or magnetic resonance imaging. Do not apply pressure to the eye. Do not patch the eye or apply any medication. E = EYE SHIELD and EVACUATE. Shield and ship to ophthalmology. The mnemonic was adapted to reflect current Joint Trauma Services and Tactical Combat Casualty Care practice guidelines. We believe this familiar mnemonic will serve as a useful tool in allowing non-ophthalmologists to comfortably and safely evaluate an eye for trauma.
