Morphology
The lexical parts are transparent—'normal' + 'tension' + 'glaucoma' suggests a type of glaucoma related to (normal) tension—so a learner could guess it's a glaucoma subtype involving 'normal tension'. However, the phrase relies on a medical, domain-specific sense of 'tension' (intraocular pressure) and the key paradox (optic nerve damage despite normal pressure) is not predictable from general meanings, making full understanding unlikely without medical knowledge.
Etymology
Normal tension glaucoma is a medical name that comes from doctors seeing the usual damage of glaucoma even though the eye's tension, or 'pressure', was normal. So, the name means 'glaucoma' that happens when eye pressure is normal.
