New multifocal phase designs aiming at expanding depth of focus in the presbyopic eye are presented. The designs consist of multiple radial or angular zones of different powers or of combined low- and high-order aberrations. Multifocal performance was evaluated in terms of the dioptric range for which the optical quality is above an appropriate threshold, as well as in terms of the area under t...

The breast-conserving treatment, in essence, implies not only providing breast-conserving surgery (BCS), but also adjuvant radiation therapy, that significantly reduces the risk of disease loco-regional and distant recurrence and is considered as an integral part of breast cancer conservative treatment [1,2]. Traditionally, appearance of more than one malignant tumor, in one or several breast q...

Purpose: The aim of this study is to explore the role of multifocal ERG in the management of patients with dry AMD and to assess the therapeutic role of oral antioxidants in dry AMD using multifocal ERG. Methods: A prospective, non randomized study was conducted in patients with dry AMD. Patients were treated with antioxidants. Ophthalmoscopic examination with multifocal ERG was performed at ba...

We report the case of a patient with multifocal motor neuropathy. Electrophysiological studies showed typical multifocal conduction blocks, but the search for anti-GM1 antibodies was negative. This case provide the heterogeneity of this clinical entity.
