Excerpt: Glaucoma is often called the “silent thief of sight.” In primary open-angle glaucoma (POAG) – the most common form worldwide – patients usually notice nothing at all until the disease is advanced (). In fact, eye doctors warn that POAG is essentially asymptomatic in early stages. The optic nerve slowly deteriorates over years, chipping away at peripheral vision without causing any pain or obvious change in sharpness. Imagine bumping into objects at the edges of your vision, missing curb steps, or failing to see people approaching from the side – these subtle clues can appear, but often go unnoticed for so long that about 40% of retinal nerve fibers are already lost before patients report any “tunnel vision” or vision loss (). By then, glaucoma’s real symptom is finally felt: the absence of any warning at all. As POAG progresses, symptoms emerge only gradually. Patients may describe difficulty discriminating contrast, or an unusual glare or halo around lights – especially when driving at night. In fact, research shows many people with glaucoma have trouble with glare and low-contrast vision (). Bright headlights or sunlit road signs may seem to wash out, and vision transition from dark to light can become jarring. These symptoms are often dismissed as normal aging or unrecognized cataracts. Over time, the visual field continues to constrict like tunnel vision, and central vision can slowly be affected. Reading small print, recognizing faces, or navigating unfamiliar routes then become more challenging. By the late stages of POAG, even straight-ahead vision can blur, greatly impacting daily activities. Acute Angle-Closure Glaucoma Unlike POAG’s silent course, acute angle-closure glaucoma presents suddenly and dramatically. This is a true emergency. Patients develop a sprinter’s warning sign of symptoms: intense eye pain, severe headache, and visual disturbances all at once. The affected eye turns red and feels very hard. Vision blurs and patients often see colored halos around lights. The episode may trigger nausea, vomiting, and even abdominal pain. In fact, one eye care protocol notes that acute angle-closure can mimic a neurological or gastrointestinal emergency: patients can be misdiagnosed with migraine, sinus headache or severe stomach sickness (). This is dangerous – without immediate treatment (often within hours) to lower the eye’s pressure, permanent vision loss can result (). In short, sudden eye pain plus headache and nausea demands an immediate emergency response. Subacute (“Intermittent”) Angle-Closure Glaucoma Some people experience intermittent angle-closure attacks – shorter, milder episodes that come and go. These attacks can cause dull brow or eye ache, foggy/blurry vision, and exploitable haloes around lights, especially after activities that dim the pupil (for example, moving into a dark room). Each episode may resolve on its own, so patients often ignore it or think it was just a bad headache. Indeed, studies found that many people with subacute angle-closure glaucoma first complain of recurring headaches and are mistakenly treated for migraines (). Because each attack is brief, it’s easy to blame them on stress or sinus troubles instead of underlying eye pressure spikes. Over time, however, these repeated IOP surges cause adhesions in the angle and l Support the show (https://www.buzzsprout.com/2563091/su...)
