| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What is the primary goal in the management of glaucoma? | 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. |
