    Abstract Purpose: Studies on age-related macular degeneration often use rod-mediated dark adaptation (RMDA) to evaluate macular functional health, studying eyes with cataract and pseudophakic eyes within the same sample. We examine a poorly understood issue-whether rod intercept time (RIT), a measure of RMDA, changes after cataract surgery and intraocular lens (IOL) insertion as compared to RIT before cataract surgery. Cataract may serve as a filter reducing photo-bleach magnitude prior to surgery, biasing RMDA interpretation.
    Methods: A pre-/post-cataract surgery design was used. Persons with nuclear sclerotic and/or cortical cataract per the electronic health record were enrolled. Prior to cataract surgery, visual acuity, RMDA, and the LOCS III classification documenting cataract presence/severity were measured. Thirty days after surgery (mean), visual acuity and RMDA were repeated, followed by fundus photos to document macular health.
    Results: Twenty-four participants (mean age 72.7 years, standard deviation 5.6) enrolled. All eyes had nuclear sclerotic and nuclear color cataract; 68% had cortical cataract. All IOLs were monofocal with 21 having blue blocking characteristics and 3 had clear IOLs. Most eyes had higher RIT post-surgery (15.6 min, SD 6.7) as compared to pre-surgery (13.7 min, SD 6.4),
    Conclusion: RMDA was significantly slower (RIT was greater) following cataract surgery, with the greatest impact on RIT in older eyes after surgery for more advanced cataract. These findings suggest that persons with more advanced cataract may bias results when evaluating RMDA using RIT.

    Abstract Importance: Little is known regarding eye care use among low-income persons with diabetes mellitus, especially African Americans.
    Objective: To investigate eye care use among patients with diabetes who were seen in a county hospital clinic that primarily serves high-risk, low-income, non-Hispanic African American patients.
    Design, setting, and participants: A retrospective cohort study with 2 years of follow-up examined eye care use among adult patients with diabetes seen in 2007 in an outpatient medical clinic of a large, urban county hospital that primarily serves low-income, non-Hispanic African American patients. Patients with a history of retinopathy and macular edema or a current diagnosis indicating ophthalmic complications were excluded. Eye care use was defined dichotomously as whether or not patients had a visit to the eye clinic for any eye care examination or procedure. We estimated crude and adjusted rate ratios (aRRs) and 95% CIs for the association between eye care use and selected clinical and demographic characteristics.
    Results: There were 867 patients with diabetes identified: 61.9% were women, 76.2% were non-Hispanic African American, and 61.4% were indigent, with a mean age of 51.8 years. Eye care utilization rates were 33.2% within 1 and 45.0% within 2 years. For patients aged 19 to 39 years compared with those aged 65 years or older, significantly decreased eye care utilization rates were observed within 1 year (aRR, 0.48; 95% CI, 0.27-0.84) and within 2 years (aRR, 0.61; 95% CI, 0.38-0.99).
    Conclusions and relevance: Overall eye care utilization rates were low. Additional education efforts to increase the perception of need among urban minority populations may be enhanced if focused on younger persons with diabetes.
