Patient 1: The patient initially has poor responses and is moving all around. You decide to do a Hirschberg/Kappa. The results are below, through your cyclo trial frame (the patient is best corrected):

Hirschberg: OD: -1.0 mm OS: -0.5 mm

Kappa: OD: +0.5 mm OS: -0.5 mm

Choose the correct interpretation

Patient 1: The child calms down. You do a full cover test:

Cyclo ret:

OD: +2.50 DS (20/40 PHNI)

OS: +1.75 DS (20/20)

PD: 55 mm

Cover test sc distance:

UCT: cover right eye, left eye doesn't move. cover left eye, right eye doesn't move

ACT: Movement out by 15 PD

Cover test sc near:

UCT: cover right eye, left eye moves out. cover left eye, right eye moves out.

ACT: Movement out by 35 PD

Cover test with cyclo ret distance:

UCT: cover right eye, left eye doesn't move. cover left eye, right eye doesn't move

ACT: Movement out by 8 PD

Cover test with cyclo ret near:

UCT: cover right eye, left eye moves out. cover left eye, right eye moves out.

ACT: Movement out by 20 PD

Based off this data alone, what is the likely diagnosis?

Patient 1: Assuming this patient has a partially accommodative ET with a comitant deviation, what would be the most likely findings on Hess Lancaster?

Patient 1: You perform Bagolini on your patient. Here are the findings, assuming glasses are put on as described in lecture:

Two lines, two lights. Lights are located above the cross.

Fusion response with 20 BO

UCT: Movement in ~ 10 PD

What is their correspondence status?

Patient 1: You use the Major amblyoscope. When measuring angle S, the patient reports that the fish is never in the tank. Without any other information, what could be happening?

Patient 1: You do a worth 4 dot on the patient. Red lens over right. These are the findings:

6 m: Light: 2 red dots. 4 dots with 12 BO. Movement out on UCT.

6 m: Dark: 5 dots, 2 red to the right. 4 dots with 12 BO. Movement out on UCT.

40 cm: 5 dots, 2 red to the right of the green dots. stable 4 dots with 15 BO. Movement out on UCT

Which of the following best describes the patient's profile?

Patient 1: You do a 4 BO test on this patient, but you forget to complete the entire procedure because you only practiced this once in lab years ago.

Prism over the right eye - right eye moves in, left eye doesn't move

Interpret the findings:

Patient 2: Your 15 year old patient comes in for their first eye exam. Their mother tells you they noticed their child may have an recent eye turn, but she seems to be a poor historian and the child says this is something that they've had all their life.

Your entrance testing shows restriction of the left eye in patient's left lateral gaze. Full and unrestricted in all other gazes.

Select all the differentials that could be possible for this patient.

Patient 2: How would you differentiate between Duane Type 1 OS and CN VI palsy OS? (Select all that apply)

Patient 3: Your 6 year old patient comes in for an eye exam because they failed a school screening.

VA: OD 20/80 distance and near

OS: 20/20 distance and near

Cyclo refraction:

OD: +0.50 DS

OS: -1.00 -0.50 x 175

Ocular health: No abnormal findings OD/OS

Cover test Dist: Ortho

Cover test Near: Ortho

With only this information, what are the most likely differential diagnoses? Select all that apply.

Patient 3:

BCVA OD: 20/80

OS: 20/20

CT: Ortho distance and near

What other data would confirm that your patient has microtropia with identity?

Patient 4: Your 6 year old patient is brought in because his mom says that his right eye turns out occasionally. Your patient has no complaints.

Cyclo ret: OD: +5.00 DS (20/100 D/N, PHNI)

OS: +3.25 DS (20/20)

Distance UCT cc: Cover left eye, right eye moves in 100% of time. Cover right eye, left eye doesn't move

Distance ACT cc: Right eye fixating 18 BI, Left eye fixating, 16 BI

Near UCT: cc Cover left eye, right eye moves in 25% of the time. Cover right eye, left eye doesn't move.

Near ACT cc: Right eye fixating: 10 BI, left eye fixating, 8 BI

Is there amblyogenic factor here? And if there is, what is the cause? (select all that apply)

Patient 4: Your 6 year old patient is brought in because his mom says that his right eye turns out occasionally. Your patient has no complaints.

Cyclo ret: OD: +5.00 DS (20/100 D/N, PHNI)

OS: +3.25 DS (20/20)

What kind of deviation does this patient have?

Patient 4: You perform Hering Bielchowsky on your patient. Initially you do it incorrectly - uncorrected. Then you do it corrected. Choose ALL the correct statements.

Patient 4: You do visuoscopy on this patient and find the following findings:

OD: See picture

OS: Steady, central fixation

Major Amblyoscope findings:

Objective angle: 25 BI

Subjective angle: 18 BI

Douse: Movement in

What type of AC does this patient have?

Patient 4: You perform Haidinger's Brush and After Image transfer on this patient. These are your results. Interpret your findings.

Patient 4: You explain to your patient that they have an intermittent exotropia. Which of the following are true that you could inform your patient/their mother. (Select all)
