Glaucoma is a group of eye diseases that lead to damage of the optic nerve, which transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. [ 5]
Pilocarpine is a drug that acts as a muscarinic receptor agonist. It acts on a subtype of muscarinic receptor ( M 3) found on the iris sphincter muscle, causing the muscle to contract - resulting in pupil constriction ( miosis ). Pilocarpine also acts on the ciliary muscle and causes it to contract. When the ciliary muscle contracts, it opens ...
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 ...
Now you do not need to go and do the most high-intensity workout. In fact, research found that 30 to 45 minutes of brisk aerobic exercises (like walking, swimming, biking, etc.) can increase blood ...
Glaucoma surgery. Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular ...
Blurred vision is an ocular symptom where vision becomes less precise and there is added difficulty to resolve fine details. Temporary blurred vision may involve dry eyes, eye infections, alcohol poisoning, hypoglycemia, or low blood pressure. Other medical conditions may include refractive errors such as myopia, high hypermetropia, and ...
Humphrey field analyser ( HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field. [1] The results of the analyser identify the type of vision defect. Therefore, it provides information regarding the location of any disease ...
Tunnel vision can be caused by: Glaucoma, a disease of the eye. [ 2] Retinitis pigmentosa, a disease of the eye. [ 3] Blood loss ( hypovolemia) Alcohol consumption. [ 4] In addition, the vision becomes blurred or double since eye muscles lose their precision causing them to be unable to focus on the same object.
