Retinal Disorders | Common Symptoms of Retinal Disorders

The retina is the third and inner coat of the eye which is a light-sensitive layer of tissue. The optics of the eye create an image of the visual world on the retina (through the cornea and lens), which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centres of the brain through the fibres of the optic nerve.<br><br>

  1. Retinal Disorders | Common Symptoms of RetinalDisorders • The retina is the third and inner coat of the eye which is a light-sensitive layer of tissue. The optics of the eye create an image of the visual world on the retina (through the cornea and lens), which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centres of the brain through the fibres of the opticnerve. • Retinal detachment itself is painless. But warning signs almost always appear before it occurs or has advanced, such as: • The sudden appearance of many floaters — tiny specks that seem to drift through your field ofvision • Flashes of light in one or both eyes • Blurred vision • Gradually reduced side (peripheral)vision • A curtain-like shadow over your visualfield • Visual distortions, such as straight lines seemingbent • Reduced central vision in one or botheyes • Decreased intensity or brightness ofcolors • A well-defined blurry spot or blind spot in your fieldof vision • A general haziness in your overallvision.
