What is cerumen impaction?
Cerumen impaction is a condition in which earwax has become tightly packed in the external ear canal to the point that the canal is blocked.
What happens if the canal of schlemm is blocked such as by tumor or clot?
The canal of schlemm normally transfers 2-3 micro liters of aqueous humor per minute. If the schlemm is blocked by clot or tumor, it results in ocular hypertension.
How will the obstruction of the canal of Schlemm will result?
Obstruction of the canal of Schlemm can lead to increased intraocular pressure, which may result in glaucoma. Glaucoma can cause damage to the optic nerve and potentially lead to vision loss if left untreated. Treatment may include medications, laser therapy, or surgery to reduce intraocular pressure and prevent further vision loss.
Types of Glaucoma?
The 2 main types of Glaucoma are Open-Angle and Angle-Closure. Apart from the two usual types, there are 8 additional types of Glaucoma, most of which are variations of Open-Angle and Angle-Closure. These variations can affect both eyes. a. Open-Angle Glaucoma This is the most common form of Glaucoma and affects the patient for life. It is caused when the eye’s drainage canal get blocked thus damaging the optic nerve. It accounts for over 90% of all Glaucoma cases. b. Angle-Closure Glaucoma Angle-Closure Glaucoma, also known as Narrow-Angle Glaucoma is the second most common type of Glaucoma. In this type, pressure in the eye is increased due to the fluid drainage because the angle in most areas between the iris and the retina are closed. Acute Angle-Closure Glaucoma is a medical emergency that requires immediate medical attention. c. Normal Tension Glaucoma Normal-Tension Glaucoma or Low-Tension Glaucoma happens when the optic nerve is damaged even when the pressure on the eye isn’t too high. The cause of Normal Tension Glaucoma is not fully known. d. Secondary Glaucoma When the increase in eye pressure leading to a damaged optic nerve has an identifiable cause like eye injury, inflammation or drugs, it is categorised as Secondary Glaucoma. Secondary Glaucoma Includes: Pigmentary Glaucoma: tiny pigment granules on the back of the iris break off into the eye liquid (aqueous humor) and become trapped in the eye’s drainage system leading to an increase in eye pressure damaging the optic nerve Congenital Glaucoma: this type is found in babies. Congenital Glaucoma occurs due to incorrect or incomplete development of the eye’s drainage canals before birth leading to increased eye pressure that damages the optic nerve Exfoliative Glaucoma: When flakes peel off the outer layer of the lens, collecting in the angle between the cornea and iris, it block the drainage system of the eye increasing eye pressure. This type of Open-Angle Glaucoma is known for causing more episodes of high pressure, fluctuations, and higher peak pressures than other types of glaucoma. Neovascular Glaucoma: This type of Glaucoma occurs due to abnormal formation of new blood vessels on the Iris that block the eye’s drainage thus increasing pressure on the eye and affecting the Optic Nerve Uvetic Glaucoma: This type of Glaucoma is caused due to an inflammation around the iris or a steroid used to treat the inflammation. The inflammation disrupts the fluid drainage leading to increased eye pressure. Traumatic Glaucoma: When an injury to the eye blocks the eye’s drainage canal, it leads to increased pressure on the eye, in turn damaging the optic nerve. It is important to stay vigilant as most forms of Glaucoma do not have any warning signs and it gets worse with age. It is recommended to get regular eye exams and pressure tests to ensure the health of your eyes. Sanjeevan Netralaya Ayurvedic treatment works on strengthening the damaged optic nerve in order to improve vision and prevent future degeneration as well as manage pain effectively and without any painful side effects.
What would happen to osteocytes if havesian canal is blocked?
If the Haversian canal is blocked, osteocytes may face nutrient and waste removal issues due to their reliance on the canal for the diffusion of essential substances. This could lead to impaired cellular function, reduced bone maintenance, and overall bone health deterioration. Ultimately, the affected osteocytes might undergo apoptosis, contributing to weakened bone structure.
What is ear wax impaction?
Impaction-- A condition in which earwax has become tightly packed in the outer ear to the point that the external ear canal is blocked.
What is the canal of schlemm in the eye?
The canal of Schlemm is a circular lymphatic-like vessel located at the anterior chamber angle of the eye, specifically where the cornea and sclera meet. It plays a crucial role in the drainage of aqueous humor, the fluid that maintains intraocular pressure and provides nutrients to the eye. Proper functioning of the canal is essential for maintaining eye health, and blockages can contribute to conditions such as glaucoma.
What is ear lavage?
Ear lavage is rinsing of the ear canal. It's a favorite way of removing impacted cerumen (blocked-up ear wax).
What are cloacogenic carcinomas?
These tumors develop in the transitional zone, or cloaca, which is a ring of tissue between the anal canal and the rectum.
Where do cattle develops the embryo?
They develop in the uterine horn, as the fetus grows, it will move into the uterus and then through the birthing canal at parturition.
What is glucoma?
Glaucoma is a group of diseases of the optic nerve involving loss of retinal ganglion cells in a characteristic pattern of optic neuropathy. Although raised intraocular pressure is a significant risk factor for developing glaucoma, there is no set threshold for intraocular pressure that causes glaucoma. One person may develop nerve damage at a relatively low pressure, while another person may have high eye pressures for years and yet never develop damage. Untreated glaucoma leads to permanent damage of the optic nerve and resultant visual field loss, which can progress to blindness.
The aqueous humor of the eye is reabsorbed into venous blood through the?
The aqueous humor of the eye is reabsorbed into venous blood through the trabecular meshwork and Schlemm's canal. This process helps maintain the appropriate pressure within the eye, known as intraocular pressure. Imbalance in the production and drainage of aqueous humor can lead to conditions like glaucoma.
