ABSTRACT

Background. Intraocular gas bubbles are commonly used in retinal surgery. There are specific management guidelines that need to be followed to ensure surgical success, and there are also unique ophthalmic and systemic complications that can occur in such patients. Objective. To educate emergency department personnel about important issues in the management of patients who have a gas-filled eye following retinal surgery. Case Report. A patient with a gas-filled eye developed several complications including pain, severe vision loss, high-grade atrioventricular (AV) block, and pneumocephalus. Conclusion. Awareness of potential problems that may arise in patients with gas-filled eyes who present to the emergency department may help minimize morbidity for such patients.

ABSTRACT

IMPORTANCE: The diagnostic accuracy of computer detection programs has been reported to be comparable to that of specialists and expert readers, but no computer detection programs have been validated in an independent cohort using an internationally recognized diabetic retinopathy (DR) standard. OBJECTIVE: To determine the sensitivity and specificity of the Iowa Detection Program (IDP) to detect referable diabetic retinopathy (RDR). DESIGN AND SETTING: In primary care DR clinics in France, from January 1, 2005, through December 31, 2010, patients were photographed consecutively, and retinal color images were graded for retinopathy severity according to the International Clinical Diabetic Retinopathy scale and macular edema by 3 masked independent retinal specialists and regraded with adjudication until consensus. The IDP analyzed the same images at a predetermined and fixed set point. We defined RDR as more than mild nonproliferative retinopathy and/or macular edema. PARTICIPANTS: A total of 874 people with diabetes at risk for DR. MAIN OUTCOME MEASURES: Sensitivity and specificity of the IDP to detect RDR, area under the receiver operating characteristic curve, sensitivity and specificity of the retinal specialists' readings, and mean interobserver difference (κ). RESULTS: The RDR prevalence was 21.7% (95% CI, 19.0%-24.5%). The IDP sensitivity was 96.8% (95% CI, 94.4%-99.3%) and specificity was 59.4% (95% CI, 55.7%-63.0%), corresponding to 6 of 874 false-negative results (none met treatment criteria). The area under the receiver operating characteristic curve was 0.937 (95% CI, 0.916-0.959). Before adjudication and consensus, the sensitivity/specificity of the retinal specialists were 0.80/0.98, 0.71/1.00, and 0.91/0.95, and the mean intergrader κ was 0.822. CONCLUSIONS: The IDP has high sensitivity and specificity to detect RDR. Computer analysis of retinal photographs for DR and automated detection of RDR can be implemented safely into the DR screening pipeline, potentially improving access to screening and health care productivity and reducing visual loss through early treatment.

ABSTRACT

BACKGROUND: For many new dental school graduates, working as an associate may be an attractive option. To provide practical information for new job-seeking dentists, the authors conducted a survey to assess dentists' preferences with regard to hiring an associate. METHODS: The authors mailed surveys to a random sample of 3,875 general dentists in four states that asked questions about the characteristics they preferred when hiring an associate. Five hundred seventy-four dentists (14.8 percent) responded to the survey. RESULTS: The results of this survey showed a wide variation in the characteristics dentists prefer when hiring an associate, but interpersonal skills appear to be at least as important as technical skills for new dentists' success. CONCLUSIONS: Opportunities for associate positions appear to be available to new dentists who have a range of skills, experience and training. Practical Implications. These results provide new dentists with information regarding the variety of career opportunities available for associates.

ABSTRACT

BACKGROUND: Ophthalmologists may be the first to hear about formed visual hallucinations in the setting of visual loss. Although such hallucinations are likely benign and occur in association with the Charles Bonnet syndrome, it is important to be aware of the strong association of hallucinations with dementia with Lewy bodies because the latter diagnosis is associated with significant prognostic and therapeutic implications for the patient. METHODS: Single case report. RESULTS: A patient with macular disease was presumed to have formed hallucinations due to the Charles Bonnet syndrome and was subsequently diagnosed with dementia with Lewy bodies after being admitted to a psychiatric facility. CONCLUSION: Both patients with the Charles Bonnet syndrome and patients with dementia with Lewy bodies can present with formed visual hallucinations. Ophthalmologists and retina specialists, in particular, should be familiar with the features of dementia with Lewy bodies because the diagnosis of this condition can allow appropriate intervention and help prevent drug-related side effects. If there is any suspicion of early dementia in such patients, they may benefit from neuropsychiatric evaluation.

ABSTRACT

PURPOSE OF REVIEW: Corticosteroids are traditionally used for inflammatory disorders because of their ability to diminish neutrophil transmigration, limit access to sites of inflammation, and decrease cytokine production. More recently, however, investigators have focused on the angiostatic and antipermeability properties of corticosteroids for posterior segment diseases such as age-related macular degeneration (AMD), diabetic retinopathy, and macular edema. Both new angiostatic and traditional corticosteroids are currently undergoing evaluation as new delivery techniques such as intravitreal injection and intraocular sustained-release devices facilitate high local angiostatic and antipermeability concentrations while minimizing extraocular toxicity. The purpose of this review is to discuss recent work concerning both the mechanism and effectiveness of these newer treatments. RECENT FINDINGS: Steroids may exert a beneficial effect in AMD-related choroidal neovascular membranes (CNVM) through inhibition of CNVM-promoting macrophages and direct inhibition of angiogenic growth factors. They may also alter extracellular matrix turnover and inhibit matrix metalloproteinases involved in CNVM formation. Intravitreal steroid injections potently inhibit experimental CNVM in primates and rats and have shown promise in some early human pilot trials. In proliferative diabetic retinopathy, steroids may directly inhibit growth factors such as vascular endothelial derived growth factor and inhibit leukocytes that play an important role in early microvascular alterations. Intravitreal steroid injections inhibit experimental preretinal neovascularization in pigs and rats, and rubeosis in some early human studies. In addition, the effect of steroids on vascular permeability has led to their use for macular edema from many causes such as diabetes and venous occlusive disease. SUMMARY: The use of steroids to treat a number of retinal diseases is gaining wide spread acceptance. The apparent short-term success must be balanced by the fact that the long-term safety and efficacy have yet to be determined for any of these approaches. A number of large randomized prospective clinical trials of steroid compounds and new delivery systems are currently under way for AMD, diabetic retinopathy, uveitis, and other retinovascular diseases, and hopefully these studies will provide guidance about the use of these new modalities.
