Most eye infections appear to originate from contact lens cases. This paper reiterates the importance of contact lens case care with the following conclusion:
"Contact lens case contamination is a significant public health concern and may contribute significantly to the development of bacterial eye disease in contact lens wearers. Patients should be reminded that they must clean and disinfect their lens cases daily, should avoid the use of tap water for rinsing them, must not top up their solutions, must take into careful consideration where and how the cases are stored during the time that lenses are being worn and that they must be replaced regularly. The adoption of these methods will substantially reduce the levels of contamination of cases with pathogenic microbes."

Patients with an average change in pressure between sitting up and laying down of 3.2mm Hg had less visual field damage than those patients with an average change in pressure of 4.5 mm Hg.
Conclusions: More advanced visual field damage was observed in eyes with greater increase in pressure with lying down. Therefore, there may be value in measuring the pressure in the supine position at the time of first diagnosis in patients with normal pressure ranges.
Clinical appraisal of tafluprost in the reduction of elevated intraocu
Purpose: The objective of this review was to assess the effectiveness of acupuncture as a treatment option for treating the condition of dry eye.
6 comparison studies were done. Three compared the effects of acupuncture with artificial tears in patients with dry eye. An analysis of the data showed that acupuncture improved signs of dry eye significantly more than artificial tears did. The other three studies compared the effects of acupuncture plus artificial tears with artificial tears alone. Two of these studies failed to show significant effects of acupuncture, while one reported significant effects. Two studies reported superior effects of acupuncture plus artificial tears, while one study failed to do so.
Conclusion: These results provide limited evidence for the effectiveness of acupuncture for treating dry eye. However, the total number of studies, the total sample size and the methodological quality were too low to draw firm conclusions.
