Diabetic retinopathy (DR) is the leading cause of legal blindness in the United States, and with the growing epidemic of diabetes, a global increase in the incidence of DR is inevitable, so it is of utmost importance to identify the most costeffective tools for DR screening. Emerging technology may provide advancements to offset the burden of care, simplify the process, and provide financially responsible methods to safely and effectively optimize care for patients with diabetes mellitus (DM). We review here currently available technology, both in production and under development, for DR screening. Preliminary results of smartphone-based devices, "all-in-one" devices, and alternative technologies are encouraging, but are largely pending verification of utility when used by nonophthalmic personnel. Further research comparing these devices to current nonportable telemedicine strategies and clinical fundus examination is necessary to validate these techniques and to potentially overcome the poor compliance around the globe of current strategies for DR screening.

Nocardial conjunctivitis associated with silicone tubing is an extremely rare finding. The authors present a case of a 52-year-old woman with previous dacryocystorhinostomy and silicone tube placement 3 years prior who presented with OD redness and discharge for 1 week. On examination, the patient was noted to have mucoid discharge and crusting surrounding the silicone tube. The tube debris was sampled, and the culture was positive for Nocardia nova complex sensitive to trimethoprim/sulfamethoxazole and amikacin. Silicone tube colonization and N. nova complex conjunctivitis are both rare but should be considered in the differential diagnosis of patients with indwelling silicone tubes presenting with chronic conjunctivitis resistant to fluoroquinolones and tobramycin.

IMPORTANCE Rear-facing sideview mirrors are a potentially reducible source of ocular morbidity following motor vehicle crashes.OBJECTIVE To report cases highlighting shattered glass from sideview mirrors as a potential cause of ocular trauma in motor vehicle crashes.DESIGN, SETTING, AND PARTICIPANTS Case series of 3 patients who presented to Grady Memorial Hospital, a level 1 trauma center and tertiary hospital, between May 5, 2017, and July 10, 2017, with ocular trauma as a result of shattered glass from sideview mirrors during motor vehicle crashes. A review of the literature was also conducted. Data were analyzed between July 2017 and August 2017. INTERVENTIONS OR EXPOSURES Operation for exploration and repair of open globe in all 3 cases. MAIN OUTCOMES AND MEASURES Visual prognosis and ocular morbidity postoperatively.RESULTS All patients were white men in the age range of 26 to 43 years. This was a retrospective review of 3 of 208 patients who presented to Grady Memorial Hospital after motor vehicle crashes from May 5, 2017, to July 10, 2017. From the time of presentation of the 3 reported patients from Grady Memorial Hospital, all 3 had 2 surgeries inclusive of the initial open globe repair. Patients with this mechanism of injury experienced ocular morbidity, with all 3 cases resulting in uveal prolapse and 2 of 3 resulting in retinal detachments. Among the 3 patients, visual acuities after the second surgery within the first year were hand motion, 20/100, and 20/150.CONCLUSIONS AND RELEVANCE Sideview mirrors can be a cause of serious ocular injuries in motor vehicle crashes. These 3 reported cases, combined with cases previously reported, suggest that this mechanism of ocular injury does occur. Further studies seem warranted to investigate the frequency of these findings and whether any design modifications may help reduce the frequency.

In-the-bag intraocular lens (IOL) dislocation is a well-known complication after cataract surgery. As the number of cataract surgeries performed annually continues to increase, so will the incidence of IOL dislocations requiring surgical correction. Described is a new technique for rescue and refixation of a single-piece acrylic IOL. In this method, a new instrument called the IOL punch is used to create a hole at the optic–haptic junction or along the border of the optic, which acts as an anchor point for centration and subsequent scleral fixation of a dislocated IOL. The IOL punch allows for precise intraocular manipulation of the IOL and is less invasive compared with popular scleral fixation methods. This innovative technique may decrease the risk for postoperative complications and allows patients to maintain or recover previous uncorrected visual acuity by circumventing the need for IOL explantation or exchange.
