Which of the following is NOT a typical glaucomatous visual field defect:* a. Nasal step b. Temporal defect c. Proximal arcuate defect d. Distal arcuate defect 2. Which of the following is NOT consistent with a diagnosis of glaucoma:* a. Vertical elongation of cup b. Elevated intraocular pressure c. RNFL thinning on OCT d. Neuro retinal rim pallor 3. Which of the following tests can be helpful in the diagnosis of glaucoma:* a. 10-2 Visual field b. 24-2c Sita Faster visual field c. Intraocular pressure measurement d. OCT Ganglion cell analysis e. All of the above 4. The SLT:MED study specifically studied prostaglandins vs. SLT as first line therapy in the United States. Its findings were:* a. SLT was superior to prostaglandins in terms of IOP reduction and therefore SLT should now be first line therapy over prostaglandins b. Prostaglandins were superior to SLT in terms of IOP reduction and therefore SLT remains only a secondary therapy after drops have been tried first c. SLT and prostaglandins were statistically equal in terms of IOP reduction and number of treatment steps d. SLT was superior to prostaglandins in terms of IOP reduction but the SLT had to be repeated every 3 months to maintain IOP reduction 5. Which of the following is NOT a type of glaucoma where an ALT or SLT is usually indicated?* a. POAG b. Low-tension glaucoma c. Angle-recession glaucoma d. Pigment dispersion glaucoma 6. The LiGHT study released in 2019 found which of the following conclusions:* a. Approximately 75% of subjects that received SLT as primary/initial therapy were drop free after 3 years b. SLT subjects had 5x less adverse events compared to initial drop therapy c. Zero subjects in the SLT arm, and 11 subjects patients in the drop arm required further surgery during the study d. SLT should be offered as primary therapy in POAG and ocular HTN, supporting a change in clinical practice e. All of the above 7. The mechanism of action by which the Selective Laser Trabeculoplasty (SLT) works is:* a. Biologic activation of macrophages and phagocytes which clean up the targeted melanin containing cells in the TM b. Mechanical photocoagulation burns which open up adjacent areas of the TM c. Burning a hole in the TM through which aqueous flows more easily d. Photodisruption laser pulses which open up areas of the TM for aqueous to flow through 8. Anytime laser energy is put into the eye, the two most commonly encountered side effects are:* a. Floaters and retinal detachment b. Inflammation and IOP spike c. Eye pain and permanent vision loss d. Corneal ulcers and macular edema 9. The energy setting that is most often initially used when performing a YAG laser PI is:* a. 0.5 mJ b. 1.3 mJ c. 3.5 mJ d. 500 mW 10. Post-laser IOP spikes are most likely to arise within which time frame?* a. 1-5 hours post-treatment b. 24-36 hours post-treatment c. 72 hours post-treatment d. 5-10 days post-treatment 11. The most common cause of narrow angles/narrow angle glaucoma is:* a. Phacomorphic glaucoma b. Malignant glaucoma c. Plateau iris syndrome d. Pupillary block 12. Which of the following is a contraindication for performing a laser peripheral iridotomy?* a. Anatomically narrow angles b. Angle closure glaucoma c. Inflammatory glaucoma d. Plateau iris configuration 13. Traditionally speaking, where are laser peripheral iridotomy (PI) holes most often placed when doing the procedure?* a. 3:00 b. 6:00 c. 11:00 d. 12:00 14. Approximately how many treatment spots/burns should be performed on 180 degrees of an eye when performing an SLT?* a. 25-30 b. 50-60 c. 100-120 d. 180-200 15. What is the tissue endpoint that the doctor usually sees while performing an SLT?* a. Charring of the tissue with champagne bubble formation b. Blanching of the tissue with champagne bubble formation c. Champagne bubble formation only d. A hole forming in the TM through which aqueous flows through 16. Which of the following drops is not recommended to be used during the post-operative period of an SLT?* a. Any glaucoma drops the patient was using before the SLT b. Alphagan c. Topical NSAID (Nevanac) d. Topical Steroid (Durezol) q2h 17. On average, how much does ALT and SLT lower intraocular pressure (IOP)? Assume the laser was done as primary therapy in a patient with POAG and 1+ pigmentation in the TM.* a. 10-15% b. 20-35% c. 40-50% d. 60-70% 18. On average, how long does it take to see the full effect of how well the SLT or ALT laser works?* a. 1 day b. 1-2 weeks c. 4-6 weeks d. 3-4 months 19. SLT has numerous advantages over ALT. They include all of the following except:* a. SLT is considered an easier laser to perform due to its mechanism of action and the fact that treatment spacing is less difficult b. SLT has been shown scientifically and clinically to be more repeatable over time c. SLT induces much less structural damage to the TM d. The SLT effect does not wear off over time whereas the ALT effect does 20. Which of the following types of glaucoma is the SLT most likely to be effective, while at the same time the energy needs to turned down to minimize potential complications?* a. POAG b. Low-tension glaucoma c. Pseudoexfoliative glaucoma d.
