[Teleconsultation network for ophthalmology--experiences and results].

MOTIVATION: Telemedical services for ophthalmology are developed within the OPHTEL project, which has been funded by the European Union and by the Bavarian government in the Bavaria-online initiative. METHODS: Seven private ophthalmologists, one university eye clinic, one clinical Diabetes center and an informatics research institute are connected within a teleconsultation network. Asynchronous (based on Internet E-Mail) and synchronous (based on ISDN-mediated videoconferencing tools) types of teleconsultations are realized. RESULTS: 86 teleconsultations (62 asynchronous, 23 synchronous) took place within the first 10 months. Complex and rare eye diseases as well as interdisciplinary questions (ophthalmology--diabetology) are the main area of medical communication interest. Legal and security problems are discussed. CONCLUSIONS: Telemedical services must be understood as a complete process of medical care on the basis of modern communication technologies, which influences also the management of this process.

Testing two elements of spirituality in depressed and non-depressed elders.

Depression is a common source of morbidity and mortality among elders in North America and has a significant impact on their quality of life. Meaning in life and self transcendence, indicators of spirituality, have been linked to the experience of well-being in the elderly. Nurses are challenged to find ways to tap these natural resources as a means of addressing the serious problem of depression in the aged. The purpose of this study was to compare patterns of depression, meaning in life and self-transcendence as measured in three instruments in a group of elders 75 years of age and older. The Geriatric Depression Scale, Purpose in Life Test and Self-Transcendence Scale were completed by 77 elders residing independently or semi-independently in one of three retirement communities. Significant negative relationships were found between depression and meaning in life, and between depression and self-transcendence. A significant positive relationship was found between meaning in life and self-transcendence. Demographic data further contributed to patterns of depression and well-being in this group. The study conclusions support the importance of meaning in life and self-transcendence for well-being in the elderly. Based on the study results, suggestions are offered about ways to enhance health and well-being in this cohort.

[Concentration of ampicillin in the vitreous after photocoagulation of the retina (author's transl)].

After photocoagulation of the retina a higher amount of ampicillin was found in the vitreous of the coagulated eyes, as our tests have shown. The reached concentrations of ampicillin were in the therapeutical region for sensitive germs. The highest concentration of ampicillin was reached when the ampicillin was injected in the edema stage of the coagulation effects. Therapeutical effective concentrations in the vitreous could be kept with this method up to five days after photocoagulation.

[Early alterations of the conjunctiva after alkali-burning (author's transl)].

Early alterations of the conjunctiva after alkaliburning (with 0.25 N NaOH) are described. After chemical damage, there is a nearly total loss of conjunctival epithelium, with simultaneous marked edema in the lower conjunctival parts. Alterations of the surface are examined by scanning electronic microscopy (SEM). Within 24 h marked infiltration of round cells into the conjunctival stroma takes place. After burning, we find a rapid decrease in the ATP level in the conjunctiva to about one-tenth of the normal value, whereas glucose and lactate showed only small alterations before and after chemical injury.
