Pharmacologic vitreolysis.

The vitreoretinal interface is involved in a wide range of vitreoretinal disorders and separation of the posterior vitreous face from the retinal surface is an essential part of vitrectomy surgeries. A diverse range of enzymatic and non-enzymatic agents are being studied as an adjunct before or during vitrectomy to facilitate the induction of posterior vitreous detachment. There is a significant body of knowledge in the literature about different vitreolytic agents under investigation for a variety of pathologies involving the vitreoretinal interface which will be summarized in this review.

Retinoblastoma in Iran: outcomes in terms of patients' survival and globe survival.

Background/aims: Retinoblastoma is a highly malignant eye tumour in children with different survival rates across the world. The aims of this study are to determine the globe and patient survival in children with retinoblastoma in a major referral centre in Iran.

Methods: 156 eyes of 105 consecutive patients with retinoblastoma were enrolled from 2001 to 2007.

A Neuro-behavioral Test and Algorithms for Screening and Evaluating Therapy in ADHD.

A new neuro-behavioral test with analysis algorithms has been developed for use in screening individuals for attention deficit hyperactivity disorder (ADHD) and for the quantitative evaluation of ADHD medication/therapy in diagnosed patients. This technique combines a 15 minute auditory-based test of attention with simultaneous EEG monitoring by a wireless, portable data acquisition device. This system acquires both behavioral response (i.

A Neuro-behavioral test and algorithms for quantification of sleepiness and characterization of wake-sleep transitions.

A neuro-behavioral test has been developed that quantifies sleepiness by means of a convenient and relatively short-duration (15 minute) protocol, and using a class of algorithms that track wake to sleep transitions. Utilizing an ambulatory EEG monitoring combined with an auditory-based vigilance test, this method acquires both behavioral response (i.e.
