Study Notes
Glaucoma MCQ Study Notes
- Glaucoma Cause: Increased intraocular pressure (IOP) is the primary cause.
- Glaucoma Risk Factors: Family history is a major risk factor.
- Most Common Glaucoma Type: Primary open-angle glaucoma.
- Glaucoma Diagnosis: Tonometry (measuring IOP) is the best diagnostic method.
- Eye Part Affected: Optic nerve is primarily affected.
- Aqueous Humor Production Reduction Drugs: Beta-blockers are commonly used.
- Prostaglandin Analog: Latanoprost is a prostaglandin analog.
- Prostaglandin Analog Mechanism: Increases aqueous humor outflow.
- Acute Angle-Closure Glaucoma Symptoms: Sudden eye pain and blurred vision.
- Carbonic Anhydrase Inhibitor: Acetazolamide.
- Medical Emergency Glaucoma: Acute angle-closure glaucoma.
- Primary Open-Angle Glaucoma First-Line Treatment: Prostaglandin analogs.
- Glaucoma Surgical Procedure: Trabeculectomy.
- Cholinergic Drug Neurotransmitter: Acetylcholine.
- Cholinergic Agonist: Pilocarpine.
- Beta-Blocker Glaucoma Mechanism: Decreases aqueous humor production.
- Normal IOP Range: 10-21 mmHg.
