During Scleral Indentation,
Keep your ___________ in your dominate hand and the ___________ in the non-dominate hand. |
Lens in DOMINATE
Indenter in NON-DOMINATE |
|
|
Where should you place the indenter?
|
Just BEYOND the TARSAL PLATE - do not put ON the tarsal plate.
|
|
|
The indenter should be place approximately ___________ to indent the ORA.
What about to indent the EQUATOR? |
7mm POSTERIOR to the LIMBUS
6-7 mm beyond the above (so about 14 mm) |
|
|
The end of your indenter is approximately ___________ long.
If orbital anatomy prevents placement for example, with a prominent brow, what should you do? What is the only type of pressure required? |
7 mm
Tip the head Tangential |
|
|
What 4 components of the optical system must be perfectly on axis t observe the indented retina?
|
1) Indented region of the fundus
2) Patient's pupil 3) Condensing Lens 4) Examiner's pupils |
|
|
6 of the most Common Errors in Scleral Indentation
|
1) "Scanning" while indenting
2) Go to your most peripheral view 3) Not getting the most anterior portion of the retina in view 4) Not placing the indenter far enough posterior 5) Indenting on brow or tarsal plate 6) Misaligned optical system |
|
|
What is GOAL 1 of Scleral Indentation?
What does this allows us to do? |
GOAL 1 : Visualize the movement of the retina
Differentiate between RETINAL HOLES and BREAKS --> Refer to RETINA SPECIALIST |
|
|
What is GOAL 2 of Scleral Indentation?
|
GOAL 2 : Have the indented area far enough into the lens that on can visualize non-indented retina around it
|
|
|
Do not indent patients with :
|
1) Penetrating OCULAR or ORBITAL injury
2) Recent intraocular surgery less than 3-4 weeks post-op 3) Be careful with IOLs and even more if they are ANTERIOR or IRIS attached IOLs. 4) For patient with HIGH IOP, it may be painful. |
