Purpose: To evaluate the correlation between tear film lipid layer thickness and other objective measurements such as tear film break-up time (TBUT), upper and lower meibomian gland losses, and Schirmer 1 test in patients with obstructive meibomian gland dysfunction (MGD) and normal controls.Design: Cross-sectional study.Methods: Thirty eyes of 30 patients with obstructive MGD and 25 eyes of 25 normal controls were enrolled. Lipid layer thickness was measured using an interferometer. Tear film stability and tear production were evaluated by TBUT and Schirmer 1 test. Upper and lower meibomian gland losses were evaluated using noncontact meibography. The correlations among variables were (Read more...)
Management of Submacular Hemorrhage Secondary to Neovascular Age-Related Macular Degeneration With Anti–Vascular Endothelial Growth Factor Monotherapy – Corrected Proof
Purpose: To report the visual and anatomic outcomes of anti–vascular endothelial growth factor (VEGF) monotherapy in the management of marked submacular hemorrhage secondary to neovascular age-related macular degeneration (AMD).Design: Retrospective,…
Toward Zero Effective Phacoemulsification Time Using Femtosecond Laser Pretreatment – Corrected Proof
Objective:
To compare effective phacoemulsification time after femtosecond laser pretreatment with conventional phacoemulsification and the associated effect on visual outcomes and endothelial cell loss.
Design:
Prospective, consecutive, single-surgeon case-control study.
Controls:
Controls underwent phacoemulsification cataract extraction plus insertion of an intraocular lens (IOL). Cases underwent pretreatment with the femtosecond laser followed by phacoemulsification cataract extraction and IOL insertion.
Methods:
Two hundred one eyes underwent cataract surgery between April 2012 and July 2012. Data collected included patient demographics, preoperative characteristics, femtosecond lens fragmentation method, effective phacoemulsification time (EPT), intraoperative complications, and postoperative outcomes.
Main Outcome Measures:
Effective phacoemulsification time, intraoperative complications, (Read more...)

Decreasing macular thickness may correspond with visual hemifield defects
Macular retinal thickness measurements diminished as visual hemifield defects increased, according to a study.The study authors said that this implies measuring macular thickness by optical coherence tomography may help predict central visual function …

Abnormal visual evoked potentials seen in infants exposed to methadone in utero
Newborns exposed to methadone in utero demonstrated abnormal visual evoked potentials, suggesting delayed visual maturation, according to a study.Such infants should be considered for early clinical visual assessment, the study authors said.
