There is a wide variety of retina problems, conditions and diseases. Here is a short list of the more common retina problems: pre-proliferative retinopathy – more severe and widespread changes affect the blood vessels, including more significant bleeding into the eye

Macular edema is a condition that occurs due to fluids building up in the macula, causing it to swell. Use prescribed magnifiers. A variety of magnifying devices prescribed by a low-vision specialist can help you with reading and close-up work, such as sewing. Such devices include hand-held lenses or magnifying lenses you wear like glasses. You may also use a closed-circuit television system that uses a video camera to magnify reading material and project it on a video screen. Over-the-counter magnifiers may not work as well. The medical laser burns the retinal tissue around the tear (this creates scar tissue that seals the tear and prevents retinal detachment) Many Windows-based Ultrabook models have offered 1080p (FHD) screens standard since 2012 and often QHD or QHD+ as optional upgrade displays.

According to the American Cancer Society, around 200–300 children in the U.S. receive a diagnosis of the condition every year.Eye surgery is the most common treatment for a torn or detached retina. There are two main types of surgery, and both are outpatient procedures. Laser Treatment (Photocoagulation) Apple says it’s the most colour-accurate LCD screen on any phone, and it has a high brightness and contrast ratio which allows it to display a wide colour gamut for HDR video and photos. Injecting medicine into the eye. Your doctor may suggest injecting medication into the vitreous in the eye. This technique may be effective in treating people with wet macular degeneration, diabetic retinopathy or broken blood vessels within the eye.

Macular degeneration (AMD)– age-related deterioration of the macula – a small part of the retina with a high concentration of cone cells, responsible for central colour vision. They will then perform a comprehensive eye exam with a particular focus on the retina and the macula. They will use a special instrument called an ophthalmoscope to investigate the inside of the eye. Hutchinson, Lee (28 October 2014). "The Retina iMac and its 5K display... as a gaming machine? [Updated]". Ars Technica . Retrieved 9 July 2015. Injecting air or gas into your eye. This technique, called pneumatic retinopexy (RET-ih-no-pek-see), is used to help repair certain types of retinal detachment. It can be used in combination with cryopexy or laser photocoagulation.

Amsler grid test. Your doctor may use an Amsler grid to test the clarity of your central vision. He or she will ask you if the lines of the grid seem faded, broken or distorted and will note where the distortion occurs on the grid to better understand the extent of retinal damage. If you have macular degeneration, he or she might also ask you to use this test to self-monitor your condition at home.

Instead, excess blue light gets scattered to the surrounding rods.This optimization is such that color vision during the day is enhanced, while night-time vision suffers very little".
