Randomized Controlled Trial Comparative Study Clinical Trial
Myopic astigmatism and presbyopia trial.
No prospective double-masked study has evaluated whether low astigmatism benefits or harms patients with presbyopia, whose intermediate and near vision might theoretically benefit from enhanced depth of focus provided by astigmatism. The purpose of the first Myopic Astigmatism and Presbyopia (MAP I) study was to determine whether low myopic astigmatism enhances or harms the visual acuity, stereopsis, or quality of life in patients with presbyopia. ⋯ This study has demonstrated that intermediate distance acuity and refractive quality of life are slightly better with spherical low myopic refractive error vs either astigmatic arm. Near and far distance acuity were unaffected by low myopic astigmatism compared with spherical low myopia. Near stereopsis was best in the ATR arms, but this did not produce better near visual acuity or RSVP quality of life.

Case Reports
Increased periocular pigmentation with ocular hypotensive lipid use in African Americans.
To report increased eyelid pigmentation as an adverse side effect associated with topical ocular hypotensive lipids in African Americans. ⋯ An increase in eyelid pigmentation and eyelash growth is a possible complication of topical ocular hypotensive lipid therapy, even in African-American patients. The changes seems to present earlier after bimatoprost treatment then after latanoprost treatment. Cessation of these medications may lead to loss of induced pigmentation.
