•
•
•
•
Presence of FB
Distorted eye lashes- trichiasis, entropion
Conjunctival concretion, calcification
Contact lenses
Black spots in front of eyes
• 1) Stationary
K scars, lens opacity
• 2) Mobile- Vitreous opacities
Headache
• Refractive errors
• Improperly corrected refractive errors
• Zoster
Haloes around light
• 1) Early ACG
• 2) Acute mucopurulent conjunctivitis
• 3) Early stages of cataract
Photopsiae
• Irritative lesions of retina
• Impending RD
Diplopia
• 1) Unioccular- high K astigmatism,
subluxated or dislocated lens
• 2) Binocular- Squint
Nyctalopia
•
•
•
•
Vitamin A deficiency
Retinitis pigmentosa
Pathological myopia
Glaucoma
Occupation
• Welders
• Black smiths- foreign body in the eye
• Farmers- fungal keratitis
Medication
• 1) Gentamicin, miotics, Atropin- follicular
response
• 2) Topical anasthetics for long timesevere corneal reactions
• 3) Topical and systemic steroids- K
disease, cataract, glaucoma
• 4) Thiomersal- allergic conjunctivitis,
epithelial Keratitis
• 5) Benzalkonium- toxic papillary reaction
Past history
• Systemic diseases- diabetis mellitus
• Arjuna-HT
• Iritis- ankylosing spondylitis
History of previous ocular disease
• Childhood squint- lazy eye
• Blunt injury- traumatic mydriasis ( could be
confused with partial third nerve palsy)
Family history
• Chronic glaucoma- the incidence nearly 5
times greater in siblings and children of
affected patients
Examination of the function of eye

• 1) Head postureParalytic squint.
Face
•
•
•
•
Look for
Asymmetry
Signs of paralysis
Obvious skin changes
Orbit
• Inspection and palpation
Eye brows
• Look for loss of hair- lepromatous leprosy,
myxoedema
• Depigmentation
Eye lid
•
1) Position of the lid
margin in relation to
cornea- drooping of lids
•
•
2) Thickness of the lid
3) Swelling
a)
b)

chalazion
GeneralisedOedema,ecchymosis

Matting- conjunctivitis
Shuklamandal (conjunctiva &
sclera)

b) Chemosisc) Subconjunctival haemorrhage
d) Pigmentation
e) Nodule
Upper tarsal conjunctiva
• Congestion
• Alteration of normal vertical vascular
pattern
• Follicle/papilla
•
•
•
•
Scarring
Membrane formation
Granuloma
Foreign body
Lower tarsal conjunctiva
• As above + any sign of symblepheron
Staining
• 2% fluorescein- raw area- green
• 1% rose bengal- conjunctiva- pinkish red
Sclera
• Colour change
• Pigmentation
• Protrusion of uveal
tissue
• Congestion
• Nodule formation
Krishnamndal (cornea & iris)
• Cornea
• 1) Size- normal (12 to 13 mm)
• 2) Curvature-conical / globular / flat
• Surface- examine by window reflex /
placido disc / slit lamp
• Irregular surface- corneal ulcer, scarring
• Depression / corneal facets
• Elevation- epithelial bulla
•
•
•
•
Opacity
1) density- nebula / macula / leucoma
2) Situation and extent in relation to pupil
3) Iris adhesion
• Pannus
(sirashuklam)• Keratic precipitates
• Corneal sensations
Diminished sensation• Herpes
• 5th nerve paralysis
• ACG and absolute glaucoma
• Leprosy
• Prolonged use of contact lens
• Post surgery
