Blind Spots In Vision

A specific blind spot known as the physiological blind spot, “blind point”, or punctum caecum in medical literature, is the place in the visual field that represents the absence of light-detecting photoreceptor cells on the optic disc of the retina where the optic nerve travels through the optic disc. Due to the fact that there are no cells to discover light on the optic disc, the corresponding part of the field of view is invisible. Some process in our brains inserts the blind spot based upon surrounding information and information from the other eye, so we do not normally view the blind spot.

    I have the very same thing. 2 large blind spots in my left eye. The greatest is on the bottom left and the other is the leading right (they appear when I am doing visual field tests but I see them during daily activities also.).
    No headaches, I am not obese, I have no other health problems.
    When they dilate my eyes and look in, they can see that my optic nerve as well as my retina has a little thinning that could contribute to this, however MRIs end up normal. Nothing had actually altered in practically 6 years till a couple months ago and I had a day that whatever through that eye appeared like I didn’t have a contact in or glasses or anything. EXTREMELY blurred, but the right eye wasn’t. Lastly it cleaned up, but my blind spots had aggravated. However at the same time, I experienced a 14 pound weight gain over 4 weeks. Not exactly sure if this relates or not however everything happened about the very same time.
