Dendritic Cell Life Cycle

Dendritic cells are mainly found in tissue that has contact with the outside environment such as the skin and the lining of the nose, lungs, stomach and intestines. The cells are also found in an immature state in the blood.

Types of Dendritic Cells

Dendritic cells are antigen presenting cells that play a key role in the immune system. Dendritic cells possess numerous long outgrowths called dendrites that give them a very large surface area of contact with their surroundings in the detection of pathogens such as bacteria and viruses. Dendritic cells have a very large contact surface area relative to their overall cell volume.

Glaucoma Management

Glaucoma needs to be detected as early as possible to prevent damage to vision. The treatment aims to reduce the pressure within the affected eye. Treatment includes medications in the form of eye drops and oral pills and surgical methods.

Glaucoma Diagnosis

Diagnosis of glaucoma is difficult based on symptoms alone. Usually the condition is diagnosed in early stages by regular screening. This is because glaucoma takes a slow course and if detected late may have already damaged the vision to a large extent. It is therefore important to have regular eye tests and screening so that problems can be detected and treated as early as possible.

Glaucoma Causes

Glaucoma results from raised intraocular pressure. The pressure usually builds up due to blockage in the drainage of the aqueous humor from the anterior chamber of the eyes.

Glaucoma Pathophysiology

The main problem or pathology in glaucoma is caused by raised intraocular pressure. It is this raised pressure that compresses and damages the optic nerve. Once the optic nerve is damaged, it fails to carry visual information to the brain and this results in loss of vision.
