|1. Check set
up of machine.
2. Observe the patient before examination. Obvious signs
may be missed on
slit-lamp such as different corneal
diameter or heterochromia.
3. Position the patient comfortably.
4. Examine the anterior segments and then the posterior segments
5. Remember to examine the fornix (scars, adrenochrome
etc) and superior
bulbar conjunctiva for abeculectomy.
6. Special note:
Learn direct, diffuse illumination, scleral scatter, specular
Look for iris transillumination
If asked, formal AC depth measure:
set slit beam mounting at 60 degrees to microscope
use horizontal slit beam
adjust slit beam to join corneal and iris reflections measure
slit length and multiply by 1.4 for AC depth in mm.
Clinical signs which may be easily missed:
pigmented lesions of the bulbar conjunctiva
deposits on cornea such as ferritin line or
pigments on the endothelium
small corneal scar
