ABSTRACT

PURPOSE: To assess whether publication of Comparison of Age-related macular degeneration Treatment Trial (CATT) results and introduction of aflibercept to the marketplace affected intravitreal bevacizumab and ranibizumab utilization. DESIGN: Retrospective analysis of treatment patterns. METHODS: We calculated weekly bevacizumab and ranibizumab utilization during 3 timeframes: (1) before CATT publication, (2) between CATT publication (April 28, 2011) and assignment of a unique aflibercept billing code (January 1, 2013), and (3) afterward for 164,188 Medicare beneficiaries with neovascular macular degeneration receiving ≥1 anti-vascular endothelial growth factor injection(s) from January 1, 2008 to December 31, 2014. We identified ophthalmologists who predominantly (≥80%) administered bevacizumab or ranibizumab and evaluated changes in preferences over the 3 periods. We replicated analyses on 881,381 commercially insured beneficiaries. RESULTS: Among 317 ophthalmologists administering predominantly ranibizumab to Medicare beneficiaries pre-CATT, 221 (69.7%) reduced ranibizumab use post-CATT, whereas 96 (30.3%) continued using ranibizumab ≥80% of the time. Findings were reversed among 1041 ophthalmologists who predominantly administered bevacizumab pre-CATT-777 (74.6%) continued bevacizumab-predominant use while 264 (25.4%) reduced bevacizumab use post-CATT. Among the 145 ophthalmologists who predominantly administered ranibizumab before aflibercept's availability, 77 (53.1%) reduced ranibizumab utilization and 68 (46.9%) continued using ranibizumab ≥80% of the time after aflibercept became available. Corresponding numbers among the 909 ophthalmologists who predominantly administered bevacizumab pre-aflibercept were 381 (41.9%) reducing and 528 (58.1%) continuing bevacizumab-predominant use. Similar results were observed for commercially insured patients. CONCLUSIONS: Many ophthalmologists who favored ranibizumab switched to bevacizumab after CATT publication, while most who favored bevacizumab before CATT publication continued favoring it afterward. Aflibercept's introduction had little impact on preferences for ranibizumab or bevacizumab.

ABSTRACT

PURPOSE: To analyze predictors of image quality for a handheld nonmydriatic fundus camera used for screening of vision-threatening diabetic retinopathy. METHODS: An ophthalmic photographer at an Aravind Eye Hospital obtained nonmydriatic and mydriatic fundus images from 3 fields in 275 eyes of 155 participants over 13 months using a Smartscope camera (Optomed, Oulu, Finland) and a Topcon tabletop fundus camera (Topcon, Tokyo, Japan). Two fellowship-trained retina specialists graded the images. Repeated-measures logistic regression assessed predictors of the main outcome measure: gradability of the fundus images. RESULTS: Of 2,475 images, 76.2% of the Smartscope nonmydriatic images, 90.1% of the Smartscope mydriatic images, and 92.0% of the Topcon mydriatic images were gradable. Eyes with vitreous hemorrhage (OR = 0.24, p < 0.0001) or advanced cataract (OR = 0.08, p < 0.0001) had decreased odds of image gradability. Excluding eyes with cataract or vitreous hemorrhage, nonmydriatic macular image gradability improved from 68.4% in the first set of 55 eyes to 94.6% in the final set of 55 eyes. CONCLUSION: With sufficient training, paraprofessional health care staff can obtain high-quality images with a portable nonmydriatic fundus camera, particularly in patients with clear lenses and clear ocular media.

ABSTRACT

Adult-onset opsoclonus-myoclonus syndrome (OMS) has been associated with multiple cancers, most commonly small-cell lung carcinoma and breast adenocarcinoma. A 53-year-old woman who presented with OMS was found to have primary central nervous system (CNS) diffuse large B-cell lymphoma. OMS has been described in only 5 cases with non-Hodgkin lymphoma (NHL), and this is only the third reported case of OMS in NHL limited to the CNS. Although the paraneoplastic antibody panel was negative, we presume that the OMS was a paraneoplastic manifestation. Antineoplastic and anti-immune therapy had no effect on the neurologic manifestations.

ABSTRACT

PURPOSE: Dry eye disease (DED) is a common ocular disease that can have adverse effects on quality of life. Our aim was to develop a single-item questionnaire that is reliable, patient-driven, and clinic friendly to assess DED symptoms and their effect on quality of life to help support the management of patients with DED. METHODS: An initial dry eye questionnaire was created and administered to 18 patients with DED followed by a 15-minute cognitive interviewing session. This questionnaire was then refined using feedback obtained from the cognitive interview and was termed the University of North Carolina Dry Eye Management Scale (UNC DEMS). Field testing was then performed on 66 patients (46 with DED and 20 without DED) to determine the validity and test-retest reliability of the UNC DEMS compared with the current gold standard, the Ocular Surface Disease Index (OSDI). Pearson correlation coefficients were calculated between the UNC DEMS, OSDI, and other DED measures to assess criterion-related validity. Reliability coefficients were estimated for test-retest reliability. RESULTS: Comparing the UNC DEMS with the OSDI across all study participants, the correlation coefficient was 0.80 (P < 0.001). Comparing the UNC DEMS with the OSDI in the DED group, the correlation coefficient was 0.69 (P < 0.001). The test-retest reliability coefficient of the UNC DEMS was estimated to be 0.90. CONCLUSIONS: The UNC DEMS is a valid, reliable questionnaire that can be efficiently administered in a busy clinical practice and can be used to support the management of patients with DED.

ABSTRACT

Dry eye is a chronic corneal disease that impacts the quality of life of many older adults. Keratoconjunctivitis sicca (KCS), a form of aqueous-deficient dry eye, is frequently associated with Sjögren's syndrome and mechanisms of autoimmunity. For KCS and other forms of dry eye, current treatments are limited, with many medications providing only symptomatic relief rather than targeting the pathophysiology of disease. Here, we review proposed mechanisms in the pathogenesis of autoimmune-based KCS: genetic susceptibility and disruptions in antigen recognition, immune response, and immune regulation. By understanding the mechanisms of immune dysfunction through basic science and translational research, potential drug targets can be identified. Finally, we discuss current dry eye therapies as well as promising new treatment options and drug therapy targets.

ABSTRACT

PURPOSE: Dry eye disease (DED) is an ocular disease that affects 5% to 17% of the US population. Because of the negative effects of DED on patients' quality of life (QOL), disease-specific questionnaires that assess QOL in patients with dry eyes are essential in the monitoring and management of this chronic ocular condition. This review provides clinicians and researchers with a summary of the current questionnaires available for assessing QOL in patients with dry eyes. METHODS: A systematic review of the literature was performed in March 2013. RESULTS: There are only 2 validated, reliable dry eye questionnaires with QOL measures currently available for clinic use: the Ocular Surface Disease Index (OSDI) and the Impact of Dry Eye on Everyday Life questionnaire (IDEEL). Multiple other dry eye questionnaires assess some degree of QOL, but they have either not been tested for validity and reliability or are limited in QOL measures they assess. CONCLUSIONS: The OSDI and IDEEL are validated, reliable disease-specific questionnaires that assess QOL measures in patients with DED. Because of its extensive development process and multiple QOL measures, the IDEEL offers a more thorough assessment of the effect of DED on QOL for clinical trials, whereas the OSDI may be the more convenient option for clinical use as a result of its shorter completion time. Other questionnaires used to assess QOL in DED (eg, 25-item National Eye Institute Visual Function Questionnaire and Texas Eye Research and Technology Center DEQ) are fairly limited in this assessment. Finally, because of the negative effects of DED on QOL, this review emphasizes the importance of including QOL measures in future questionnaires for the monitoring and management of DED.
