Content and boundaries of medicine in long-term care: physicians talk about stroke.

Twenty physicians were interviewed about roles, treatments, goals, and relationships with older patients, especially stroke patients. Findings from this descriptive, anthropological investigation address the problem of congruence between needs and existing services, and in doing so, recast the ongoing debate about the medicalization of long-term care. This study emphasized the nonmedical features of geriatric medicine in general and stroke care in particular. In many instances, these physicians attempt to bridge gaps between medical and emotional needs and clinical and social services with social and psychotherapeutic as well as biomedical interventions. Because we found physicians' activities with stroke patients to be so broadly construed, treatment and management of stroke may be seen as paradigmatic for the role of physicians in long-term care.

Laser treatment of diffuse retinal pigment epitheliopathy.

The Authors report laser treatment of 18 eyes (14 patients) with a variant of central serous chorioretinopathy associated with widespread decompensation of the retinal pigment epithelium (RPE) in the macula, diffuse retinal pigment epitheliopathy (DRPE). All eighteen eyes with DRPE were treated with Krypton red laser photocoagulation in a grid pattern to leaking RPE in areas of neurosensory retinal detachment. All eyes showed anatomic improvement with resolution of the serous macular detachment and lipid exudation. The visual acuity was stabilized in 15 eyes (83%) at 6 months' follow-up, but only 3 eyes (17%) demonstrated improved visual acuity in the same time interval. At eighteen months, 2 of 15 eyes (13%) retained improved visual acuity, 11 eyes (74%) remained unchanged, and 2 eyes (13%) had visual loss. In this series of patients with DRPE, grid laser photocoagulation treatment was uniformly successful in producing an anatomic improvement in the exudative manifestations of the macula and in preventing or slowing progression of vision loss.

The effects of distraction on smooth pursuit in normal subjects.

Smooth pursuit eye movements made in response to 5 and 20% targets were studied in young and old subjects. Tracking of a target was carried out both with no competing stimuli and while auditory and visual distractions were presented. Only tracking the target against a projected background significantly impaired pursuit. It did so in both age groups, by reducing pursuit gain and also by eliciting 'anticipatory saccades', which took the eyes ahead of the target to a new fixation point for 0.5 s or longer. Elderly subjects showed a significantly greater number of such interruptions, however, suggesting that continuous performance of the tracking task could be more readily disrupted in this group. These findings may arise from changes in the way in which elderly individuals process incoming sensory information.
