ReviewPatient expectations for medical and surgical care: a review of the literature and applications to ophthalmology.
Over the past several decades, emphasis on patient-centered care, the dramatic growth of refractive surgery in the United States, and increasing competition in the eye care marketplace have made patient expectations increasingly important in the field of ophthalmology. Patient-centered care recognizes the obligation to understand and meet patient's expectations. Despite increasing patient expectations for refractive surgery and eye care in general, however, there has been limited research on patient expectations within the field of ophthalmology. ⋯ Using elements of the taxonomy developed by Kravitz (Kravitz RL: Patients' expectations for medical care: an expanded formulation based on review of the literature. Med Care Res Rev 53:3-27, 1996), this article reviews the existing literature on patient expectations and draws attention to the limited research in specialty and surgical fields. This article has the following objectives: 1) provide a context for understanding what patient expectations are, 2) review the different ways that patient expectations are measured, 3) illustrate the content of patient expectations from empirical research, 4) outline potential determinants of patient expectations, and 5) discuss the role of patient expectations in ophthalmology.

Health care economic analyses are becoming increasingly important in the evaluation of health care interventions, including many within ophthalmology. Encompassed with the realm of health care economic studies are cost-benefit analysis, cost-effectiveness analysis, cost-minimization analysis, and cost-utility analysis. Cost-utility analysis is the most sophisticated form of economic analysis and typically incorporates utility values. ⋯ This improvement in value can then be amalgamated with discounted costs to yield expenditures per quality-adjusted life-year ($/QALY) gained. $/QALY gained is a measure that allows a comparison of the patient-perceived value of virtually all health care interventions for the dollars expended. A review of the literature on health care economic analyses, with particular emphasis on cost-utility analysis, is included in the present review. It is anticipated that cost-utility analysis will play a major role in health care within the coming decade.

Review Case ReportsTwo discrete choroidal melanomas in an eye with ocular melanocytosis.
We report a case of multifocal choroidal melanoma arising in an eye with ocular melanocytosis and review the pertinent literature. A 63-year-old Caucasian male with ocular melanocytosis in the left eye was found to have two discrete choroidal melanomas in the same eye. ⋯ On the basis of random chance, patients with two melanomas in the same eye would be expected to have approximately 1000-fold greater likelihood of underlying ocular melanocytosis than the general Caucasian population. In conclusion, multifocal choroidal melanoma is rare and may be related to underlying ocular melanocytosis.

ReviewClostridium botulinum and the ophthalmologist: a review of botulism, including biological warfare ramifications of botulinum toxin.
The anaerobic bacterium Clostridium botulinum causes disease by elaborating an extremely potent neurotoxin that inhibits release of acetylcholine at presynaptic nerve endings, thereby resulting in a descending flaccid paralysis and autonomic nervous system dysfunction. Possible ophthalmological effects of this neurotoxin are many and typically constitute the earliest manifestations of botulism. ⋯ Ophthalmological findings of botulism are tabulated and their frequencies are provided. Finally, the bioterrorism/biologic warfare ramifications of botulinum toxin are briefly discussed.

Every year in the USA, 100-150 people die and 1000-1500 others are injured by lightning strikes. Ophthalmic and neurologic injuries from lightning strike are common. ⋯ Prompt evaluation by an ophthalmologist is imperative for maximizing outcomes. Incidence and mechanisms of lightning strike injury are summarized, with special emphasis on the treatment of ocular injuries.
