Purpose: To investigate the relation between intraocular pressure (IOP) and the idiopathic long anterior zonule (LAZ) trait. Methods: Patients presenting for primary eye care were examined for LAZ, identified as radially oriented zonular fibers with central extension >1.0 mm beyond the normal anterior lens insertion zone (estimated via slit lamp beam length). Ocular, systemic health, and lifestyle data were collected via comprehensive exam and questionnaire. Multivariate regression was used to assess the relationship between IOP (Goldmann) and LAZ...

REVIEW
Darren Shu Jeng Ting, Sathish Srinivasan, Jean-Pierre Danjoux
The number of laser in situ keratomileusis (LASIK) procedures is continuing to rise. Since its first application for correcting simple refractive errors over 25 years ago, the role of LASIK has extended to treat other conditions, including postkeratoplasty astigmatism/ametropia, postcataract surgery refractive error and presbyopia, among others. The long-term effectiveness, predictability and safety have been well established by many large studies. However, due to the creation of a potential interface between the flap and the underlying stroma, interface complications such as infectious keratitis, diffuse lamellar keratitis and epithelial ingrowth may occur...

Objective: Ready-made spectacles have been suggested as a less resource-intensive treatment for the millions of people living with uncorrected refractive error (URE) in low-income environments. In spite of this interest, there have been no published economic evaluations examining the cost-effectiveness of ready-made spectacles. This study aims to determine the relative cost-effectiveness of offering ready-made spectacles (RMS) relative to no intervention as well as the relative cost-effectiveness of custom-made spectacles (CS) relative to RMS to treat URE...

During postnatal refractive development, an emmetropization mechanism uses refractive error to modulate the growth rate of the eye. Hyperopia (image focused behind the retina) produces what has been described as "GO" signaling that increases growth. Myopia (image focused in front of the retina) produces "STOP" signaling that slows growth. The interaction between GO and STOP conditions is non-linear; brief daily exposure to STOP counteracts long periods of GO. In young tree shrews, long-wavelength (red) light, presented 14 h per day, also appears to produce STOP signals...
