Aim of this presentation
· To present a method of systematic thinking for identification of fundus lesions .
Fundus Regions
90 D Biomiocroscope
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
Elevated Lesions
Color Level
retinoblastoma
Nevus
hemangioma
hamartoma
· Morphology
· Movement
· Multiplicity and extent

Cause ?
Color code
Black lesions
Yellow lesions
Hard drusen
Soft drusen
Stargartd disease
Best disease
Choroidal rupture
Red Lesions
· Red
· Remote
· Raised distinct edges
· Revealed by indentation
White lesions
Cilioretinal artery occlusion
Berlin edema
Distorted anatomy
· Optic disc lesions
· Blood vessel abnormalities
