Self-application of single-use eyedrop containers in an elderly population: comparisons with standard eyedrop bottle and with younger patients.

Purpose: To test whether patients aged >or=80 years can safely and successfully apply eyedrops from a single-use eyedrop container without support, and to compare the results with those of younger patients using single-use containers and older patients using standard eyedrop bottles.

Methods: Patients aged >or=80 years who had no physical or mental conditions hindering self-application of eyedrops and actually did so because of glaucoma or dry eyes were included consecutively in the study group (n = 44) in order to perform self-application of eyedrops from single-use eyedrop containers. Patients were observed meticulously by two investigators, who documented practical problems during the procedure in a checklist.

Signal quality of biometry in silicone oil-filled eyes using partial coherence laser interferometry.

Purpose: To assess the practical feasibility and signal quality of axial length measurements by partial coherence laser interferometry in silicone oil-filled eyes with previous complicated vitreoretinal surgery.

Settings: Department of Ophthalmology, University Cologne, Cologne, Germany.

Methods: Using a Zeiss IOLMaster, axial length measurements and signal-to-noise ratios of optical biometry in silicone oil-filled eyes (n=45) and contralateral eyes without tamponade (n=41) were analyzed.

Neodymium:YAG laser capsulotomy in vitrectomized pseudophakic eyes with persistent endotamponade.

Purpose: To evaluate the feasibility and limits of neodymium:YAG (Nd:YAG) laser capsulotomy in eyes with persistent endotamponade.

Setting: Department of Ophthalmology, University Cologne, Cologne, Germany.

Methods: In this consecutive series, an Nd:YAG laser capsulotomy was performed by 1 surgeon in 6 eyes with posterior capsule opacification (PCO) and persistent endotamponade caused by proliferative vitreoretinopathy.

The short-term effect of latanoprost on intraocular pressure and pulsatile ocular blood flow.

Purpose: There is evidence that ocular blood flow plays a critical role in the clinical course of glaucoma. Any reduction in ocular blood flow due to topical antiglaucoma treatment should therefore be avoided. This study aimed to evaluate the short-term effect of local latanoprost application on ocular hemodynamics.
