MCQ Options:
a. Lights off; narrow beam; below eye level; 30 degrees; low mag
b. Lights on; wide beam; at eye level; 45 degrees; high mag
c. Lights on; narrow beam; above eye level; 60 degrees; medium mag
d. Lights off; wide beam; at eye level; 90 degrees; high mag

Answer 1

The correct setup for examining the Anterior Chamber involves room lights off, a narrow beam, a beam height at pupil level, a 30-60 degree lamp angle to the microscope, and low to medium magnification.

Step-by-step explanation:

When examining the Anterior Chamber of the eye using a slit lamp microscope, the correct setup would involve having the room lights off to enhance contrast, using a narrow beam to form a thin optical section or parallelpiped through the cornea and anterior chamber, setting the beam height to intersect the eye at or just below pupil level. The angle of the slit lamp should be set at around 30 to 60 degrees to the microscope for optimal visualization of structures like the cornea, iris, lens, and their relationships. Frequently, a low to medium magnification is employed to provide a suitable overview and adequate detail without sacrificing depth of field.Adjust the beam height to a level that allows you to see the desired structures effectively. Set the lamp to a 30-degree angle to the microscope to avoid glare. Use a lower magnification for a wider field of view and better overall examination.
