Study Notes
Glaucoma Overview
- Defined as an eye condition that can lead to vision loss, characterized by damage to the optic nerve.
- Two primary types: open-angle glaucoma and angle-closure glaucoma.
Open-Angle Glaucoma
- Pretrabecular issues involve factors before the trabecular meshwork, affecting aqueous humor drainage.
- Trabecular problems directly impact the trabecular meshwork, leading to impaired outflow.
- Consequences include loss of retinal fibers, optic neuropathy, and visual field defects.
Angle-Closure Glaucoma
- Condition features the drainage angle closure, but sometimes occurs without pupillary block.
- Secondary glaucoma refers to increased intraocular pressure (IOP) due to other ocular conditions.
Pathophysiology
- Neurotrophic Transport Block: Disruption in the transport of neurotrophins from the brain to retinal ganglion cells (RGCs).
- Apoptosis Activation: Series of processes leading to programmed cell death of RGCs.
- RGC Death: Apoptosis results in the loss of retinal ganglion cells and subsequent vision impairment.
Key Takeaways
- Understanding both types of glaucoma is crucial for diagnosing and treating the condition effectively.
- Awareness of the underlying pathophysiological mechanisms can guide interventions to prevent vision loss.
