Comparative Study
Comparison of measurements of refractive errors between the hand-held Retinomax and on-table autorefractors in cyclopleged and noncyclopleged children.
To compare the measurement of refractive errors (sphere, cylinder, and axis) between the hand-held Retinomax and on-table Topcon autorefractors in cyclopleged and noncyclopleged young children. The average bias and measurement agreement were assessed. ⋯ The data by the Retinomax were consistent with those by the Topcon. The Retinomax is a useful instrument to screen refractive errors in young children.

To present two cases of uveal melanoma presenting as acute angle-closure glaucoma. ⋯ Although acute angle-closure as the initial presentation of uveal melanoma is rare, the presence of a uveal melanoma should be suspected in eyes unresponsive to medical therapy, especially in unilateral cases in which the view of the posterior segment is obscured.

Randomized Controlled Trial Multicenter Study Clinical Trial
Outcomes of surgery for retinal detachment associated with proliferative vitreoretinopathy using perfluoro-n-octane: a multicenter study.
To report visual acuity and anatomical outcomes, as well as complications, of management of complex retinal detachment with proliferative vitreoretinopathy using pars plana vitrectomy and intraoperative perfluoro-n-octane (PFO), and to investigate clinical features associated with anatomical and visual acuity outcomes. ⋯ In the management of complex retinal detachment associated with proliferative vitreoretinopathy, pars plana vitrectomy and use of intraoperative PFO was associated with retinal reattachment and preserved visual acuity in most eyes.

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.
