Glaucoma and retinal disorders

Glaucoma is a group of progressive eye diseases in which the optic nerve degenerates over time, most often driven by elevated intraocular pressure that damages the retinal ganglion cells responsible for transmitting visual signals to the brain. Left undetected or undertreated, it is one of the leading causes of irreversible blindness worldwide, making early diagnosis and long-term monitoring critical clinical priorities. Researchers are working to understand why some patients lose vision despite well-controlled pressure while others tolerate high pressure without apparent harm, pointing to complex interactions among vascular, genetic, and neurodegenerative factors that current models do not fully explain. Advances in optical coherence tomography now allow clinicians to detect structural changes in the optic nerve and retinal layers before patients notice any vision loss, and ongoing work aims to translate that structural data into better predictions of who will progress and how quickly.
