5.3 Retinal Detachments
The retina is one of the three layers of the human eye. The innermost layer
is a complex and delicate layer (0.4mm in thickness) which lines the innerside
of 2/3rds of eyeball. There are a number of sub-layers to this tissue which
comprise the neural layers and photoreceptors necessary for vision.
Detachment of the retina is a separation of the neural retina from the pigment
epithelium; a layer of pigment cells providing nutrients to the photreceptors
and attaching the retina to the next outermost layer - the choroid. As a
result of the separation there is a loss of function in the photoreceptors,
vision is affected.
The accompanying symptoms of a retinal detachment include; blurring of vision,
sensation of "flashing lights", loss of vision like a shade or curtain moving
across the field of vision. The presence of a retinal detachment is a serious
visual problem and should be thoroughly investigated by an eyecare professional.
Retinal detachment occurs in some hereditary conditions, e.g Stickler
Syndrome. More information is available on the Web at
