[1] It affects nearly 1 in 2 Americans and remains as a ...
Ocular hypertension. Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [1] [2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3] [4] Elevated intraocular pressure is an important risk ...

[2] The main symptoms are headache, vision problems, ringing in the ears, and shoulder pain.
These changes make certain tasks, including reading and driving, particularly difficult, but macular degeneration rarely impairs mobility because it doesn’t affect peripheral vision, Diaconita says.
