Fundus Regions

Indirect Ophthalmoscope+

Scleral Indentation

· 9 Regions ± Scleral depression

Once a lesion is found

Is it elevated ? Is it colored ? Is it distortion of normal anatomy ?

Elevated ?

1- Border

2- Blood vessels

3- Light reflection.

4- Light Focus

Double vessel effect = shallow RD
