<p>Considers the effects of incorporating mortality risk, a potentially important factor to consider when deciding whether to initiate therapy for ocular hypertensives, into estimates of 5-year glaucoma risk.</p>

<p>To examine the association between severity of visual field loss (VFL) and self-reported health-related quality of life (HRQOL) in a population-based sample.</p>

<p>Overall performance of the NEI VFQ in Latino populations is adequate.</p>

<p>To assess the impact of unilateral and bilateral visual impairment (VI) and its severity on health-related quality of life (HRQOL) in Latinos 40 years and older.</p>

<p>Many eye care patients prefer to be treated by specialists with expertise in their conditions.</p>

<p>This study suggests that, in many respects, patients with POAG are receiving care that is consistent with the PPP. However, care is falling short on several key aspects, and POAG may be undertreated relative to standards for IOP control established in recent clinical trials.</p>

<p>The similarity of problems mentioned across refractive error type and correction method suggests it will be possible to develop a single questionnaire with adequate content validity to compare the impact of different modes of correction in vision-targeted, health-related quality of life.</p>

<p>The NEI-RQL is responsive to changes in vision-targeted health-related quality of life resulting from keratorefractive surgery.</p>

<p>Evaluates the associations of presbyopia and its correction, particularly monovision optical correction, with vision-targeted health-related quality of life.</p>

<p>To better inform study design decisions when sampling patients within health plans and physician practices with multiple analysis goals.</p>

<p>These results provide evidence supporting the validity of the RAND-UCLA method to assess the appropriateness of surgery.</p>

<p>These results support the reliability and construct validity of the NEI-RQL.</p>

<p>The reliability and validity of the NEI VFQ-25 are comparable to those of the 51-item NEI VFQ field test version of the survey. This shorter version will be more feasible in settings such as clinical trials where interview length is a critical consideration.</p>

<p>Visual and hearing impairment appear to have a significant relationship to overall functioning in the oldest old. By confirming these findings across income and household wealth groups in a nationally representative population of Americans age 70 years or older, this study provides a powerful added impetus to efforts for improving vision and hearing for all other Americans, including the oldest old.</p>

http://www.rand.org/pubs/external_publications/EP19980904.html Dec 31, 1997 Dec 31, 1997

<p>This study aimed to determine the relationship between visual function impairment in 776 patients who had extracapsular cataract extraction with posterior chamber intraocular lens implantation and gender, age, preoperative visual acuity of both the operative and the contralateral eye, and presence of other ocular disease in the operative eye.</p>

<p>Little has been published that directly assesses the effect of structures for providing managed care or the effects of capitated, prepaid financing on the cost and quality of eye care services.</p>

http://www.rand.org/pubs/external_publications/EP19970039.html Dec 31, 1996 Dec 31, 1996

<p>Examines variation in the use of procedures e.g. cataract extraction in Medicare prepaid and fee-for-service (FFS) settings. The study was based on a cross-sectional analysis using 1993 Medicare claims and encounter files. The main outcome was age and risk-adjusted rates of cataract extraction per 1,000 beneficiary-years. After controlling for age, sex, and diabetes status, the authors found that FFS beneficiaries were twice as likely to undergo cataract extraction as were prepaid beneficiaries, and that female FFS beneficiaries were nearly twice as likely to undergo the procedure as were male FFS beneficiaries.</p>

<p>The authors examine the use of eye care services among the 1991 Medicare population based on claims from a representative 5% sample of Medicare beneficiaries.</p>
