Explanation:
The Krimsky test uses a prism to center the corneal reflex when assessing ocular alignment. By observing the position of the corneal light reflex relative to the center of the pupil, the examiner can determine the presence and magnitude of strabismus or misalignment of the eyes.
Explanation:
When interviewing a patient with a chief complaint of headaches, ethnicity is typically not pertinent to the assessment of the headache. Instead, aspects such as the duration, cause, and date of onset of the headache are more relevant for diagnosis and treatment planning.
Explanation:
When a patient complains of a "red eye," it's essential to ask about associated symptoms like blurred vision, as it could indicate more serious underlying conditions such as corneal inflammation, uveitis, or glaucoma.
Explanation:
Sudden loss of vision is a symptom that requires prompt attention because it can indicate a serious condition that needs immediate medical intervention. While the other symptoms are concerning, sudden vision loss is most urgent.
Explanation:
"Primary" is not a classification of fixation. Central, steady, and maintained fixation refer to different aspects of how the eyes focus on an object. Central fixation refers to focusing on the central point of an object, steady fixation means maintaining focus without wandering, and maintained fixation implies continued focus over time.
Explanation:
Patient history is obtained by asking specific questions in an orderly sequence to gather information about the patient's symptoms, medical history, and any relevant factors that may impact their eye health. This step is crucial in understanding the patient's condition and guiding further examination and treatment. Refraction, tonometry, and visual field testing are important components of the eye examination, but they do not involve asking specific questions to gather patient history.
Explanation:
A chief complaint is the primary symptom or concern that brings a patient to seek medical attention. "Eye fatigue" is a symptom described by the patient, making it a chief complaint. The other options are clinical findings or medical history details.
Explanation:
The Mallett unit (MA) is used to quantify the magnitude and direction of phorias in both vertical and horizontal planes at distance and near. Therefore, option A is incorrect; the test can be used to measure both vertical and horizontal phorias at a distance and near.
Explanation:
Keratoconus is a common familial ocular disorder that affects the shape of the cornea and should be recorded during a patient's history. The other conditions listed are not primarily ocular disorders.
Explanation:
"Intraversion" is indeed not a designation of a version. The prefix "intra-" typically denotes movement inward or within. In the context of eye movements, "intra-" usually refers to convergence, the inward movement of both eyes toward each other.
Explanation:
The chief complaint or reason for the patient's visit. This is a crucial step in history-taking as it helps prioritize the patient's concerns and guides the examination.
