Approaches to lowering intraocular pressure, including medications, laser therapy, and surgical procedures.
The primary goal is to lower intraocular pressure (IOP) to prevent or slow optic nerve damage and preserve visual function. |
| Think of IOP as the pressure that needs to be controlled to protect the optic nerve. |
| 2 | Name the main classes of medications used to lower intraocular pressure in glaucoma. | Prostaglandin analogs, beta-blockers, alpha-adrenergic agonists, carbonic anhydrase inhibitors, and cholinergic agents (miotics). | Consider the different mechanisms like increasing outflow or decreasing production. |
| 3 | How do prostaglandin analogs lower intraocular pressure? | They increase uveoscleral outflow of aqueous humor, thereby reducing IOP. | Think 'Prostaglandins promote outflow.' |
| 4 | Which medication class is often the first-line therapy for glaucoma? | Prostaglandin analogs, due to their efficacy and once-daily dosing with minimal systemic side effects. | Remember 'First-line' starts with P for Prostaglandin. |
| 5 | What is the mechanism of action of beta-blockers in glaucoma treatment? | They decrease aqueous humor production by blocking beta-adrenergic receptors in the ciliary body. | Beta-blockers reduce 'production' of fluid. |
| 6 | Name a common topical carbonic anhydrase inhibitor used in glaucoma. | Dorzolamide or brinzolamide. | Think 'CO₂' inhibitors reducing aqueous humor production. |
| 7 | What is the role of laser trabeculoplasty in glaucoma management? | It enhances aqueous outflow through the trabecular meshwork by applying laser energy, often used as initial or adjunctive treatment in open-angle glaucoma. | Laser increases outflow pathway efficiency. |
| 8 | Which type of laser is commonly used for laser trabeculoplasty? | Argon laser or selective laser trabeculoplasty (SLT). | SLT is a preferred, less destructive option. |
| 9 | What is the main indication for laser iridotomy in glaucoma? | To treat or prevent angle-closure glaucoma by creating an opening in the iris to facilitate aqueous flow between the posterior and anterior chambers. | Think 'Iridotomy opens the iris.' |
| 10 | Describe a key feature differentiating primary angle-closure glaucoma from primary open-angle glaucoma. | Primary angle-closure glaucoma involves a physically narrowed or closed angle impeding aqueous outflow, often with a sudden onset; open-angle glaucoma has an open anterior chamber angle with gradual IOP increase. | Angle status distinguishes the two types. |
| 11 | What surgical procedure is typically performed when medical and laser therapies fail in glaucoma management? | Trabeculectomy, which creates a new drainage pathway to lower IOP. | Think 'trabeculectomy = new drainage route.' |
| 12 | What are the main risks associated with trabeculectomy? | Potential risks include hypotony, infection, bleb leaks, and scarring leading to failure of the procedure. | Risks relate to the new drainage pathway. |
| 13 | Name a minimally invasive glaucoma surgery (MIGS) device or procedure. | iStent, Trabectome, or Gonioscopy-assisted transluminal trabeculotomy (GATT). | MIGS are less invasive options with quicker recovery. |
| 14 | How does glaucoma drainage device (tube shunt) surgery differ from trabeculectomy? | It involves implanting a tube to divert aqueous humor to a reservoir, suitable for refractory cases or when trabeculectomy is contraindicated. | Tube shunts provide an alternative pathway via an implant. |
| 15 | What is the typical post-operative care after glaucoma surgery? | Use of topical antibiotics and steroids, monitoring for hypotony or infection, and regular IOP assessments. | Post-op care aims to prevent complications and ensure healing. |
| 16 | Which medication class is contraindicated in patients with active ocular infections or inflammations? | Certain topical steroids or immunosuppressive agents; caution is needed to avoid masking infections. | Always assess for active eye infections before immunosuppressive therapy. |
| 17 | What is the purpose of combination therapy in glaucoma treatment? | To achieve greater IOP reduction by using medications with different mechanisms, often allowing lower doses and reducing side effects. | Think 'combining forces' for better control. |
| 18 | Which factor influences the choice between medical versus surgical treatment in glaucoma? | Severity of disease, IOP level, response to medications, patient compliance, and presence of contraindications or side effects. | Tailor treatment to individual patient factors. |
| 19 | What is the significance of target IOP in glaucoma management? | It is the individualized IOP level aimed to prevent or slow optic nerve damage, often set based on baseline damage and risk factors. | Target IOP is the goal for effective treatment. |
| 20 | How does the use of prostaglandin analogs compare to beta-blockers in efficacy? | Prostaglandin analogs generally lower IOP more effectively with once-daily dosing and fewer systemic side effects compared to beta-blockers. | Prostaglandins are often first choice for efficacy. |
