Normal variants of ora serrata

a	b	c	a. Meridional fold
			• Small radial fold in line with
			a dentate process
			• Occasionally small hole at base

b. Enclosed oral bay

• May be mistaken for retinal hole

c. Granular tissue

• Multiple, tiny, white opacities

• May be mistaken for small opercula

Anatomy of vitreous base

Pars

Plicata

Pars

Plana

Vitreous base

•3-4 mm wide zone straddling ora serrata

•Strong adhesion of cortical vitreous

•Anterior limit of posterior vitreous detachment

Indirect ophthalmology

Condensing lenses

Technique

• The higher the power, the less the	•	Keep lens parallel to patient’s iris plane
magnification, the shorter the working	•	Avoid tendency to move towards patient
distance but the greater the field of view	•	Ask the patient to move eyes and head
	•	Ask the patient to move eyes and head
		into optimal positions for examination

Slitlamp biomicroscopy

Goldmann triple-mirror lens

View of peripheral fundus

• Equatorial mirror (largest and	• Image is upside down
oblong) - from 30 to equator

•Peripheral mirror (square) - from equator to ora serrata

•Gonioscopic (smallest)

Primary retinal break

It is responsible for RD and determines configuration of SRF

Quadratic distribution of breaks in eyes with RD

Configuration of SRF in relation to primary break

PATHOGENESIS AND SIGNS OF

RETINAL DETACHMENT (RD)

1.Rhegmatogenous RD

•Fresh

•Longstanding

•Proliferative vitreoretinopathy (PVR)

2.Diabetic tractional RD

3.Exudative RD

4.Differential diagnosis RD

Pathogenesis of rhegmatogenous RD

Two components for retinal break formation

•Acute posterior vitreous detachment (PVD)

•Predisposing peripheral retinal degeneration

Possible sequelae of acute PVD


Uncomplicated PVD (85%)	Retinal tear formation and	Avulsion of retinal vessel and
	haemorrhage (10-15%)	haemorrhage (uncommon)

Predisposing peripheral degenerations
