The examination of the angle of the anterior chamber of the eye with a magnifying device known as

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2024

Explanation

Gonioscopy is the specific diagnostic procedure used to visualize the iridocorneal angle, which is the angle at the junction of the cornea and iris.
This examination is performed using a special lens called a gonioscope, which is placed on the patient's cornea.
It is essential for diagnosing and managing glaucoma by determining if the angle is open or closed, which dictates the treatment approach.

Option A: Ophthalmoscopy is used to examine the back of the eye (fundus), including the retina and optic nerve, not the anterior chamber angle.
Option B: An otoscope is a medical device used to look into the ears, not the eyes.
Option D: A probe is a general, non-optical instrument used for exploring body cavities or wounds. It is not used for magnifying and examining the structures of the eye.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Diagnostic Procedures for Eye Examination as background academic context rather than a clinical decision trigger.
Differentiating between open-angle and angle-closure glaucoma is a critical nursing assessment point, as the management and urgency differ significantly. Gonioscopy is the definitive test for this.
A nurse assisting in an ophthalmology clinic must be able to prepare the patient for gonioscopy, which includes explaining the procedure and administering topical anesthetic eye drops.
What if? If a patient presents to the emergency department with sudden, severe eye pain, nausea, and blurred vision with halos around lights, the nurse should suspect acute angle-closure glaucoma. The priority is to facilitate an urgent ophthalmology consult for IOP measurement and gonioscopy, as this is a sight-threatening emergency.

How to Approach the Question

First, identify the key terms in the question: 'examination', 'angle of the anterior chamber', and 'eye'. This points to a specific diagnostic procedure in ophthalmology.
Next, evaluate each option based on its known medical function.
Eliminate 'Otoscope' immediately, as it is used for the ear.
Eliminate 'Probe' as it is a general, non-specific term and not a magnifying device for the eye.
Differentiate between the remaining two eye-specific options: 'Ophthalmoscopy' and 'Gonioscopy'. Recall that ophthalmoscopy is for the back of the eye (fundus), while gonioscopy is specifically for the anterior angle.
Conclude that 'Gonioscopy' is the correct term that matches the specific anatomical location mentioned in the question.
