Skryté šilhání : Kdy může škodit

Skryté šilhání navzdory své incidenci není v laické populaci známým termínem. Autor si klade za cíl tuto skutečnost pomocí článku alespoň částečně napravit.Skryté šilhání navzdory své incidenci není v laické populaci známým termínem. Autor si klade za cíl tuto skutečnost pomocí článku alespoň částečně napravit.The term "latent strabismus" or "heterophoria" is not very known in the non-professional population. Author's purpose is to explain this dilemma to the general public in an easy-to-understand form

Binocular Refraction in Patients with Age-Related Macular Degeneration

We’ve been finding possible association of central vision damage with binocular vision disorders in our clients suffering from age-related macular degeneration (ARMD), but whose visual acuity still allowed us to examine their binocular vision. Our findings show that there is a significant number of patients with heterophoria in horizontal, as well as vertical direction. The clients rate the vision with prismatic correction as more comfortable, clearer and long-term tolerable. Getting used to prismatic correction was spontaneous and non-problematic. Based on these results we expect to find possibly the most effective rehabilitation of vision in patients suffering from ARMD

The saturation of decaying counterflow turbulence in helium II

We are concerned with the problem of the decay of a tangle of quantized vortices in He II generated by a heat current. Direct application of Vinen's equation yields the temporal scaling of vortex line density $L \sim t^{-1}$. Schwarz and Rozen [Phys. Rev. Lett. {\bf 66}, 1898 (1991); Phys. Rev. B {\bf 44}, 7563 (1991)] observed a faster decay followed by a slower decay. More recently, Skrbek and collaborators [Phys. Rev. E {\bf 67}, 047302 (2003)] found an initial transient followed by the same classical $t^{-3/2}$ scaling observed in the decay of grid-generated turbulence. We present a simple theoretical model which, we argue, contains the essential physical ingredients, and accounts for these apparently contradictory results.Comment: 19 pages, 5 figure
