Concept
Open-Angle Glaucoma is a chronic eye condition characterized by gradual damage to the optic nerve, often due to increased intraocular pressure, leading to irreversible vision loss if untreated. It is the most common form of glaucoma and progresses slowly, often without noticeable symptoms until significant vision loss has occurred.
Relevant Fields:
Concept
Intraocular pressure (IOP) is the fluid pressure inside the eye, crucial for maintaining the eye's shape and proper function. Abnormal IOP levels can lead to conditions like glaucoma, potentially causing vision loss if not managed effectively.
Concept
Optic nerve damage refers to harm inflicted on the optic nerve, which can lead to vision loss or blindness, often resulting from conditions like glaucoma, trauma, or inflammation. Early detection and treatment are crucial to prevent irreversible damage and preserve vision.
Concept
Visual field loss refers to a partial or complete loss of vision in a specific area of the visual field, often resulting from damage to the optic nerve, retina, or brain. It can significantly impact daily activities and quality of life, necessitating early diagnosis and tailored management strategies to address the underlying cause and mitigate its effects.
Concept
Tonometry is a diagnostic procedure used to measure intraocular pressure, which is crucial for assessing the risk of glaucoma. Accurate measurement of intraocular pressure helps in the early detection and management of glaucoma, potentially preventing vision loss.
Concept
Ophthalmology is the branch of medicine and surgery that deals with the diagnosis and treatment of eye disorders. It encompasses a wide range of conditions from common vision problems to complex diseases like glaucoma and macular degeneration.
Concept
The trabecular meshwork is a crucial structure in the eye's anterior chamber that regulates intraocular pressure by controlling the outflow of aqueous humor. Dysfunction or blockage of this meshwork can lead to increased intraocular pressure, contributing to conditions such as glaucoma.
Concept
Concept
Concept
Angle-closure glaucoma is a critical eye condition where the drainage angle formed by the cornea and iris closes, leading to a rapid increase in intraocular pressure. Immediate medical intervention is necessary to prevent permanent vision loss due to optic nerve damage.
Concept
Ocular hypertension refers to higher-than-normal pressure inside the eye, which can increase the risk of developing glaucoma, a leading cause of blindness. Regular monitoring and treatment are crucial to prevent damage to the optic nerve and preserve vision.
Concept
Perimetry is a diagnostic procedure used to assess the visual field, helping to detect and monitor diseases that affect peripheral vision, such as glaucoma. It involves the systematic measurement of the scope and sensitivity of vision, providing crucial data for eye health evaluation and management.
Concept
Gonioscopy is a diagnostic procedure used by ophthalmologists to visualize the anterior chamber angle of the eye, which is crucial for diagnosing and managing glaucoma. It involves the use of a special lens to overcome the optical limitations of the cornea, allowing for the assessment of the drainage angle and identification of any abnormalities.
Concept
Retinal ganglion cells are crucial neurons in the retina that transmit visual information from photoreceptors to the brain via the optic nerve. They play a vital role in processing visual signals and are involved in various aspects of vision, including contrast sensitivity, motion detection, and circadian rhythm regulation.
Concept
Neuroprotection refers to strategies and interventions that aim to preserve neuronal structure and function in the central nervous system following acute injuries or in chronic neurodegenerative diseases. It encompasses a variety of approaches including pharmacological treatments, lifestyle modifications, and therapeutic interventions to prevent or halt neuronal damage and promote recovery.
Concept
Glaucoma treatment primarily aims to lower intraocular pressure to prevent damage to the optic nerve and preserve vision. This can be achieved through medications, laser therapy, or surgery, depending on the severity and type of glaucoma.
Concept
Laser Trabeculoplasty is a medical procedure used to treat open-angle glaucoma by improving the drainage of aqueous humor through the trabecular meshwork, thereby reducing intraocular pressure. It is a minimally invasive option that can be performed multiple times and is often used when medications are insufficient or not tolerated by the patient.
Concept
The anterior chamber angle is a critical structure in the eye where the cornea and iris meet, playing a vital role in the drainage of aqueous humor through the trabecular meshwork to maintain intraocular pressure. Proper functioning of this angle is essential for preventing conditions like glaucoma, which can lead to vision loss if left untreated.
Trabecular Meshwork Dysfunction is a condition affecting the eye's drainage system, leading to increased intraocular pressure and potentially resulting in glaucoma. It involves the impairment or blockage of the trabecular meshwork, which can be due to genetic, environmental, or age-related factors, disrupting the outflow of aqueous humor.
Selective Laser Trabeculoplasty (SLT) is a non-invasive laser treatment used to lower intraocular pressure in patients with open-angle glaucoma by targeting the trabecular meshwork. It utilizes a low-energy laser to selectively stimulate the natural drainage pathways of the eye, improving aqueous outflow without causing thermal damage to surrounding tissues.
Concept
Argon Laser Trabeculoplasty (ALT) is a medical procedure used to treat open-angle glaucoma by improving the drainage of aqueous humor through the trabecular meshwork, thereby reducing intraocular pressure. It is a non-invasive outpatient procedure that utilizes an Argon Laser to create controlled burns in the eye's drainage system, enhancing fluid outflow and helping to preserve vision.
Concept
Glaucoma is a group of eye conditions characterized by damage to the optic nerve, often associated with increased intraocular pressure, leading to progressive vision loss. The pathophysiology involves impaired aqueous humor drainage, resulting in pressure buildup that damages retinal ganglion cells and their axons.
Concept
Glaucoma is a group of eye conditions that damage the optic nerve, often linked to high intraocular pressure, and is one of the leading causes of irreversible blindness worldwide. Early detection and treatment are crucial to prevent vision loss, as the disease often progresses without noticeable symptoms until significant damage has occurred.
Concept
Glaucoma risk assessment involves evaluating various factors such as intraocular pressure, optic nerve health, and family history to determine an individual's likelihood of developing glaucoma, a group of eye conditions that can lead to vision loss. Early identification of high-risk individuals enables timely intervention to prevent or slow the progression of the disease.
