2. Purpose
*Permanent, universally acceptable
records of the disease process
*Useful reference at the time of surgery
*Comparison
*In clinical research & review

3. Basic Materials
*Examination table
*Indirect Ophthalmoscope
*Condensing lenses
*Scleral Depressor
*Coloured pencils
*Clipboard
*Fundus drawing charts

13. TIPS FOR DRAWING FUNDUS
DIAGRAM
•Whatever appears closer to the observer in the
condensing lens is peripheral (anterior)
•Observe the disc and trace a vessel to the periphery
•Observe the macula last for best patient’s
cooperation

16. Draw As U See

21. RED
Solid
•Retinal arterioles
•Neovascularization (flat-blue,
raised-green outline)
•Vascular anomalies
•Attached retina
•Haemorrhages
(pre/intra/subretinal)
•Open,interior portion of retinal
breaks
•Open, interior portion of outer
layer holes in retinoschisis
•Normal foveola ( drawn as a
red dot)
Crosslined
•Open portion of giant tears or
dialyses
•Inner portion of CRA
•Open portion of retinal holes in
inner layer of retinoschisis
•Inner portion of thin areas of
retina.

23. BLUE
Solid
•Detached retina
•Retinal veins
•Outlines of retinal breaks
•Outline of ora serrata
•Meridional,radial, fixed &
circumferential folds
•Retinal tags and tufts
•Outline of lattice
•Outline of thin areas of retina
•Outline of flat neo-
vascularization
•Intra-retinal cysts
Crosslined
•Inner layer of retinoschisis
•White with or without pressure
•Detached pars plana epithelium
•Rolled edges of retinal
tears/inverted flaps of GRT
Circled : cystoid degeneration
Interruped lines
•Outline of change in area of
detached retina because of
shifting fluid

25. GREEN
Solid
•Media Opacities
•Vitreous Haemorrhage
•Vitreous Membranes
•Weiss Ring
•IOFB
•Retinal Opercula
•Cotton wool patches
•Silicone oil
•Outline of raised NVE
Stippled or dotted
•Asteroid hyalosis
•Frosting or snowflakes on
cystoid, retinoschisis or
lattice degeneration

27. BROWN
Solid
•Pars plana cysts
•Ciliary Processes
•Pigment beneath detached
retina
•Pigment Epithelial
Detachment
•Outline of posterior
staphyloma
•Choroidal naevi
•Malignant choroidal
melanoma
•Other choroidal tumors
•Choroidal Detachment
Outline
•CRA beneath detached retina
•Posterior staphyloma
•Edge of buckle beneath
detached retina

30. Colour Coding-Yellow-solid
~ I\R oedema
~ I\R, S\R hard yellow exudate
~ Deposits in the RPE
~ Detached maculae in some retinal
seperations
~ Post-PHC retinal edema
~ Substance of long & short ciliary nerves
Yellow –stippled-
~ Drusen

32. BLACK
Solid
•Choroidal pigmentation in
attached retina
•Pigment in choroid or
pigmented epithelial
hyperpigmentation in areas of
attached retina
•Pigmented demarcation lines
at attached margin of detached
retina or within detached retina
•Hyperpigmentation due to
previous cryo/phc/diathermy
•Sheathed retinal vessels
Outline
•Edge of buckle beneath
attached retina
•Outline of Chorioretinal
atrophy
•Outline of Long & Short Post
Ciliary vein & nerve
