Changes in corneal endothelium cell characteristics after cataract surgery with and without use of viscoelastic substances during intraocular lens implantation.

Purpose: To evaluate whether the use of balanced salt solution (BSS) or an ophthalmic viscoelastic device (OVD) during hydrophilic acrylic intraocular lens (IOL) implantation variously impacts corneal endothelial cell characteristics in eyes undergoing uneventful phacoemulsifications.

Methods: Prospective nonrandomized observational clinical trial. Patients were assigned either to the BSS plus(®) or to the OVD Z-Celcoat™ group depending on the substance used during IOL implantation.

[Retinal detachment in Ehlers-Danlos syndrome. Treatment by pars plana vitrectomy].

Unlabelled: Ehlers-Danlos syndrome (EDS) is an hereditary connective tissue disorder caused by defective collagen synthesis, the main features being hyperelasticity and vulnerability of the skin, recurrent bleeding from fragile blood vessels, and secondary deformities of the joints. Ocular involvement is a rare occurrence, e.g.

Low-dose radiation therapy for age-related macular degeneration.

Background: The study was carried out to evaluate the effect of low-dose radiation therapy in patients with age-related macular degeneration.

Methods: One hundred eyes of 78 patients (mean age 72 years) with different forms of age-related macular degeneration were treated with external beam radiotherapy between 1971 and 1989. In four fractions a total dose of 2 Gy was administered over 7 days.

Silicone oil for recurrent vitreous hemorrhage in previously vitrectomized diabetic eyes.

Aims: To investigate the clinical course of vitrectomized patients with recurrent diabetic vitreous hemorrhage who were treated by revitrectomy with silicone oil (SO) as a hemostyptic tamponade.

Patients And Methods: Fifteen patients with recurrent vitreous hemorrhage due to proliferative diabetic vitreoretinopathy were included in this retrospective study. All eyes had had at least one vitrectomy prior to use of SO and the retina was completely attached at any time before revitrectomy with SO instillation.
