People often assume they would notice a serious eye problem because their vision would blur or hurt, but glaucoma usually does not work that way. The damage tends to creep in from the edges of vision first, and by the time a person recognizes the change, some of the loss may already be permanent. That is why glaucoma screening matt
The Science Behind OCT Scan Glaucoma Detection in Optometry
Glaucoma rarely announces itself in a dramatic way. Most patients walk into a glaucoma eye exam feeling fine, seeing well, and assuming that “no symptoms” means “no problem.” That assumption is exactly why modern optometry relies so heavily on imaging and functional testing. Among those tools, the OCT scan has become one of the most valuable ways to detect structural change long before a patient notices a field defect or a drop in vision. What makes OCT scan glaucoma ass
