Retinal laser treatment has a success rate of around 90 to 95 percent. Most retinal tears are effectively treated and don’t require re-retreatment. Some people experience retinal tear enlargement (despite surgery). Between 1011 and 1021 CE, Ibn Al-Haytham published numerous experiments demonstrating that sight occurs from light reflecting from objects into the eye. This is consistent with intromission theory and against emission theory, the theory that sight occurs from rays emitted by the eyes. However, Ibn Al-Haytham decided that the retina could not be responsible for the beginnings of vision because the image formed on it was inverted. Instead he decided it must begin at the surface of the lens. [78] Recovery time after surgery for a detached retina varies. But as a general guide, for 2 to 6 weeks after surgery: The photoreceptor connecting cilia which bridge the inner and outer segments of the photoreceptor cells.Dowling, John (2007). "Retina".

S2CID 4415311. The energy requirements of the retina are even greater than that of the brain. [4] This is due to the additional energy needed to continuously renew the photoreceptor outer segments, of which 10% are shed daily. [4] Energy demands are greatest during dark adaptation when its sensitivity is most enhanced. [42] The choroid supplies about 75% of these nutrients to the retina and the retinal vasculature only 25%. [5] Steve Jobs painted Apple into something of a corner when he described the pixels in the iPhone 4 as imperceptible to the human eye. Where do you go from there? How do you describe a screen that’s even better? Apple’s answer has been to borrow terminology from the video and broadcast industries.So, for example,theiPhone 4, 5, 6, 7 and 8 all have screens with a pixel density of 326ppi, while Plus versions have a higher density of 401ppi. The iPhone X, XS and XS Maxhave pixel densities of 458ppi.
