Slowing the progression of myopia has become a considerable concern for parents of myopic children. At the same time, clinical science is rapidly advancing the knowledge about methods to slow myopia progression. This article reviews the peer-reviewed literature regarding several modalities attempting to control myopia progression. ⋯ However, low-concentration atropine has been shown to provide effective myopia control with far fewer side effects than 1.0% atropine. Finally, two agents, low-concentration atropine and outdoor time have been shown to reduce the likelihood of myopia onset. Over the past few years, much has been learned about how to slow the progression of nearsightedness in children, but we still have a lot to learn.

Randomized Controlled Trial
Propofol and dexmedetomidine for monitored anesthesia care during laser in situ keratomileusis.
The safety and efficacy of dexmedetomidine during laser in situ keratomileusis (LASIK) in stressed patients under topical anesthesia has not been fully investigated. ⋯ Dexmedetomidine in conjunction with topical anesthesia offered better conscious sedation for nervous patients during LASIK, but these patients required a longer recovery period.

To evaluate the resolutions of slit-lamp microscopy photography using various cameras. ⋯ Several cameras can be adapted with slit-lamp microscopy for ophthalmic imaging, yielding various display and image spatial resolutions. However, the resolution seemed to not be as good as ocular viewing through the slit-lamp biomicroscope.

To examine the effectiveness of heating contact lens cases after disinfection on reducing microbial contamination. ⋯ Using a warming device for contact lens cases after a disinfection cycle with an MPDS during drying for 3 hours results in substantial kill of biofilms of P. aeruginosa and S. aureus that have been formed in the wells of the cases.

ReNu with MoistureLoc (ReNuML), containing the antimicrobial agent alexidine 0.00045%, was associated with the Fusarium keratitis epidemic of 2004 to 2006. Although a single-point source contamination was ruled out, only Fusarium organisms were reported during the outbreak. This study investigated whether the reported loss of antimicrobial effectiveness toward Fusarium of ReNuML after exposure to heat in high-density polyethylene (HDPE) plastic containers could also be demonstrated with other common fungal and bacterial agents of keratitis. ⋯ Heating of an alexidine solution in ReNu HDPE plastic (but not glass) containers results in the same loss of anti-Fusarium activity as reported when testing the original ReNuML solution. This loss of inhibitory activity is not specific to Fusarium and occurs with other fungi and bacteria that cause keratitis. The reasons for the lack of reports of bacterial and/or non-Fusarium fungal keratitis during the original Fusarium keratitis epidemic remain unclear at this time.
