CONTRIBUTION FACTORS OF EFFECTIVE LENS POSITION, TILT, AND DECENTRATION DURING FLANGED SCLERAL FIXATION OF INTRAOCULAR LENS: A Model Eye Study.

Purpose: The authors aimed to elucidate the factors related to effective lens position, tilt, and decentration of scleral fixed intraocular lenses (IOLs) with a flanged haptic technique in an artificial eye model using anterior segment optical coherence tomography.

Methods: Two bent 27-gauge needles were passed through a 1.0- or 2.

A discrete parasubthalamic nucleus subpopulation plays a critical role in appetite suppression.

Food intake behavior is regulated by a network of appetite-inducing and appetite-suppressing neuronal populations throughout the brain. The parasubthalamic nucleus (PSTN), a relatively unexplored population of neurons in the posterior hypothalamus, has been hypothesized to regulate appetite due to its connectivity with other anorexigenic neuronal populations and because these neurons express Fos, a marker of neuronal activation, following a meal. However, the individual cell types that make up the PSTN are not well characterized, nor are their functional roles in food intake behavior.

Lichen planus confined to a radiation therapy site.

We report the case of a 58-year-old man with lichen planus localized to a radiation site. To our knowledge, this is the first reported case of radiation-induced lichen planus in the English-language literature.
