Eye care when using video display terminals.

OBJECTIVE: To examine the scientific data in the literature regarding eye problems and possible damage during the use of computer video display terminals. DATA SOURCES: Medline and non-Medline literature search and personal experience. STUDY SELECTION: Studies that provided evidence-based information about eye damage and eye care during the use of video display terminals were selected. DATA EXTRACTION: Data were extracted independently by multiple observers. DATA SYNTHESIS: Most studies have shown that the levels of ionizing and non-ionizing radiation that are emitted by video display terminals are not harmful to the human eye. Eye complaints associated with the use of video display terminals include the McCollough effect, accommodative spasm, 'dry eyes', and eye strain. Ergonomic considerations and good visual hygiene can help alleviate symptoms. CONCLUSION: There is currently no convincing evidence that shows that using video display terminals is harmful to the eye.

OphthWeb---cost-effective telemedicine for ophthalmology.

'OphthWeb' is an ophthalmic electronic medical record that can be accessed locally and globally via the Internet. OphthWeb can provide secure multimedia patient data to doctors, patients, and health care providers at any time and in any place. Patients have secured access to their own records in the convenience of their homes or during any emergency at any time or place around the world. OphthWeb provides interactive educational information and answers frequently asked questions by way of multimedia images on the Worldwide Web. A data transmission trial was conducted between the Xiamen Eye Centre in the Fujian province in southern China and Singapore. Clinical records, voice messages, and fundus and slit-lamp images were transmitted from Xiamen, and an off-line dialogue by e-mail and Internet-relay chat was conducted. The time delay from transmission to receipt was 30 minutes, which would be adequate to respond to most ophthalmic emergencies. This pilot project will promote computer literacy among doctors, and inter-institutional interaction in the health care profession. OphthWeb can provide telemedicine and electronic medical records at a low cost and great convenience.

Epidemiology of severe childhood eye injuries that required hospitalisation.

We conducted a retrospective study of all paediatric ocular injuries that were treated at the Prince of Wales Hospital between October 1991 and January 1997. Of the 60 injuries reviewed, eight (13.3%) resulted in some degree of visual deficit. The mean age was 5.5 years and the average male to female ratio was 2.75:1. The distribution of injuries was as follows: contusions, 29 (48.3%); non-penetrating lacerations, 14 (23.3%); penetrating lacerations, six (10.0%); chemical burns, six (10%) and superficial foreign bodies, five (8.3%). Thirteen (21.7%) ocular injuries were associated with common household items, seven (11.7%) injuries were due to toy gun pellets, and five (8.3%) injuries were sports-related. A total of 28 operations were performed on 21 patients, and the mean duration of hospital stay was 3.6 days. The visual outcome depended mainly on the type and severity of the injury. Some childhood eye injuries are preventable by means of more public education, improved safety measures, and closer adult supervision.
