This patient couldn’t catch a break—post-LPI dysphotopsias led to suture closure, then a hyphema.

What can we learn?
Temporal > superior for fewer dysphotopsias.

200–400 µm—enough for patency, less light scatter.

Symptoms: 2–5%, reduced by lid coverage & smaller/temporal PIs.

The lens power in the vertical meridian is -1.00 D. The patient is reading 10 mm below the distance optical center. Using Prentice’s rule, PD = 1 D x 1 cm = 1 PD. Because the patient is viewing through the bottom half of the minus lens, the prism direction is BD.

A patient wears SRx +1.00 DS -2.00 DC x 180 with a +3.00 D round 28 bifocal segment. If the top of the segment is 5 mm below the distance optical center, and the patient reads 5 mm below the top of the segment, calculate the image displacement due to the distance prescription.

Ciprofloxacin and clarithromycin interfere with the metabolism of warfarin, and ceftriaxone destroys the normal intestinal flora, leading to a reduction in vitamin K absorption and a higher risk of bleeding. Tetracycline does not interfere with warfarin.

Patients with a chronic dry mouth and dry eye should be evaluated for Sjogren’s syndrome with a salivary gland biopsy. ACE and chest x-ray are indicated for suspected sarcoidosis. Syphilis IgG is indicated for syphilis. ELISA and Western blot aid in the diagnosis of HIV.

A 45-year-old female complains of bilateral burning, tearing, and foreign body sensation that worsens throughout the day OU. She also has a history of chronic dry mouth. Which test(s) is/are MOST appropriate to further evaluate this patient’s condition?

Approximately 5% of patients with myasthenia gravis also have thyroid disease; thus T3, T4, and TSH testing is most appropriate to perform. A chest CT scan may also be indicated, as 10% of patients with MG have a thymoma.

Your patient presents with unilateral eyelid ptosis that worsens at the end of the day and improves with the ice pack test. Which of the following tests is MOST appropriate to further evaluate the patient?

An FA is not indicated. Patients with retinal emboli, acute RAOs, or amaurosis fugax are at a greater risk for strokes. They should be referred immediately for a CT or MRI. A carotid ultrasound and cardiac studies are also warranted to determine the source of the embolus.

[KMK Optometry @KMKOptometry]

A patient presents with symptoms of amaurosis fugax and a Hollenhorst plaque causing a BRAO OS. All of the following tests are indicated EXCEPT:

The thinnest area of the sclera (0.3 mm) is located underneath the recti tendons and is thus most vulnerable to inadvertent globe penetration. The thickest area of the sclera is located at the posterior pole (1.0 mm). The lamina cribrosa is the weakest area of the sclera.

[KMK Optometry @KMKOptometry]

Damage to which area of the sclera during strabismus surgery is MOST likely to result in globe penetration?

Parasympathetic fibers travel with the greater petrosal nerve of CN VII before synapsing at the pterygopalatine ganglion. Postganglionic parasympathetic fibers join the zygomatic branch of V2, then join the lacrimal nerve of V1 to innervate the lacrimal gland.

[KMK Optometry @KMKOptometry]

Which of the following ganglia provide parasympathetic innervation to the lacrimal gland to stimulate aqueous secretion?
