• Synonymous with the term ablephary
8. Cryptophthalmos
* A condition
characterized
by the
presence of an
eyelid without a
palpebral
fissure
9. ANKYLOBLEPHARON

• It is characterized by an adhesion between the
upper and lower lid margins
• The horizontal diameter of the palpebral
fissure is lesser than normal
10. SYMBLEPHARON
* This is an
adhesion between
palpebral and bulbar
conjunctiva
15. BLEPHAROPHIMOSIS
It is a condition
characterized by a
decreased size of the
palpebral fissure both
vertical and horizontal
16. EPICANTHUS
* It is the most
common congenital
abnormalities and is
present among infants
It is characterized by
the presence of a
vertical skin fold in the
medial canthal region
that covers the medial
angle and caruncle
It is also known as
palpebranasal fold
28. Symptoms of Entropion
• Foreign body sensation
• Watering
• Redness
• Pain
• Photophobia
These symptoms are due to rubbing of ocular
surface by misdirected eyelashes
48. Cicatricial Ectropion
• Is out-rolling of lid marging due to contraction
of scar tissue on skin side. Commonly results
from lid trauma, burns, chemical injuries and
chronic inflammations of lid skin. Due to
contraction of scar the lid skin shortens pulling
the eyelid away from the eyeball
51. Paralytic Ectropion
• This condition is due to paralysis of the facial nerve due to
Bell palsy, surgery on parotid gland and trauma
• Characterized by presence of other signs of facial palsy
• Initially treated by conservative treatment by taping of lids,
lubricating eye drops, till there is recovery
• Lateral tarsorrhaphy, by suturing freshened upper and lower
lids at outer canthus
• Lagophthalmos due to weakness of superior orbicularis may
be treated by taping
53. Ectropion
• Ectropion, or eversion of the lid margin, may be
congenital or acquired
• The acquired forms are the result of
– Ageing changes (involutional)
– Lumps (mechanical)
– Scarring of the anterior lamella of the lid (cicatricial)
• Burn
• Infection/ inflammation
• Trauma
– Weakness of the orbicularis muscle (paralytic)
68. Marcus Gunn Jaw-Winking
syndrome
- Also called Trigemino-oculomotor Synkineses
- Autosomal dominant
- In this congenital ptosis there is miswiring of the
nerve supply to the pterygoid muscle of the jaw
and the levator of the eye so that the eyelid
moves in conjugation with movements of the
jaw.
Treatment
Treatment is usually unnecessary but in severe
cases, surgery with a bilateral levator excision
and frontalis brow suspension may be used.
74. BLEPHAROSPASM

207. Entropion
- It is an inturning, usually of the lower lid towards the
globe.
- Patients present with irritation caused by eyelashes
rubbing on the cornea.
- more common in elderly, because orbcularis muscle
become spasm.
- it may also caused by Conjuctival scarring distorting
the lid (cicatrical entropion)
Treatment:

eye or taping of the eyelid.
Permenant :surgery
208. Lower lid retractors
a. Inferior lid retractors:
1. The inferior tarsal aponeurosis – capsulo-
palpabral expansion of the inferior rectus
muscle and is analogous to the levator
aponeurosis
2. Inferior tarsal muscle is analogous to
muller muscle
209. Entropion
Entropion is in-rolling of eye lid margin.
Normal position of sharp posterior border of inter-
marginal strip is essential for interigrity of the tear
film and for maintenance of healthy ocular surface
Entropion is caused by disparity of length and tone of
anterior skin muscle layer and posterior tarso-
conjunctival layer of the eyelid
210. Symptoms of Entropion
• Foreign body sensation
• Watering
• Redness
• Pain
• Photophobia
These symptoms are due to rubbing of ocular
surface by misdirected eyelashes
211. Involutional Entropion
This condition is due to old age, due to
instability of lid structures
There occurs:
a. Weakness of the posterior retractor of the
lid
b. Laxity of medial and lateral canthal
ligaments
c. Atrophy of orbital pad of fat leading to
enophthalmos
212. Involutional Entropion
• There occurs of over-ridding of preseptal
orbicularis muscle over pretarsal orbicularis,
that leads to forward rotation of tarsal plate
• Seen in lower lids
213. Treatment of Involutional Entropion
Principles of surgery
2. Reattachment of the retractor to tarsal plate
3. Shortening of horizontal width of lid
4. To induce scarring between the pre-tarsal
and pre-septal parts of orbicularis muscle
214. Surgical Procedures
1. Catgut suture application through
2. Modified Bick operation: Horrizontal
shortening of lower lid with fixation to
lateral canthal ligament and periosteum
3. Tucking of inferior lid retractors

217. Spastic Entropion
• This condition is due to spasm of orbicularis in
presence of degeneration of the palpabral
connective tissue separating orbicularis fibres. The
spasm is induced by local irritation in inflammatory
and traumatic conditions.
• Factors that prevent in-rolling of lid margin:
a. intact inferior lid aponeurosis which maintains
orbicularis in position that it presses against lower
tarsus
b. contraction of palpabral head of inferior rectus
218. Mechanism
• Degeneration of aponeurosis, the strong
contraction of orbicularis is associated with
turning inwards of lid margin
• Senile degeneration of tarsal muscle of Muller
fails to anchor the lower border of tarsal plate
to bony orbit
• Orbicularis rides up on tarsal plate towards lid
margin
• Horizontal lid laxity
219. Clinical picture

irritation, tight bandaging
• Treatment of surface disorder by artificial
tears and control of conjunctival infection and
lid inflammation with antibiotic
• Fixing of lower lid after everting it with
adhesive tape
• Injection of Botulinum toxin into pre-tarsal
orbicularis to weaken it
221. Surgical treatment
• Producing a ridge of fibrous tissue in the
orbicularis to prevent its fibres from sliding in
vertical direction
222. Congenital Entropion
• This condition is due to dysgenesis of lower lid
retractor or due to abnormal development of
tarsal plate.
• This condition must be differentiated from
epiblepharon (due to anomalous fold of skin
pushing lashes upwards onto the eyeball)
• Treatment of abnormality
224. Lower lid retractors

251. Involutional Ectropion
Stages:
2. Early stage: in mild cases on looking up the
puncta is not apposed to bulbar conjunctiva
3. Progresses to moderate stage puncta are
not apposed to bulbar conjunctiva even in
primary gaze and entire lid margin fall away
from the globe
252. Involutional Ectropion
3. In severe case lower lids are rolled out and palpabral
conjunctiva (including tarso-conjunctiva and fornix
are exposed)
Chronic exposure of lower puncta on everted lid leads
to phimosis of puncta
Tears are no longer drained into nose and overflow
onto the cheek
In long standing cases keratinization of the lid margin
and palpabral conjunctiva takes place
253. Signs
• Signs as described with three stages earlier
• In ling standing cases the exposed conjunctiva
becomes dry, thickened, red , un-sightly. Cornea may
suffer from imperfect closure of the lids
• Diagnosis is confirmed if lower lids does not snap
back into position after pulling it 6-7 mm away from
globe. If canthal displacement is more than 2 mm on
pulling lower lid laterally or medially , canthal laxity is
diagnosed
• There is horizontal lengthening of the lids
254. Treatment
• Surgical treatment:
in mild to moderate cases, excision of 7 – 8 mm long
x 4 mm high conjunctival exicion 5 mm below lid
margin (puncta), this puts back puncta in its normal
position
In more marked cases 5 mm full thickness
shortening/ resection of lid 5 mm from puncta, by
giving inverted house shaped incision (modified
Kuhnt Szymanowski operation at lateral canthus or
modified Lazy T operation at medial canthus)
255. Treatment
• Principle of surgery:
release and relaxation of the scar tissue and
restoration (elongation) of skin by
blepharoplasty
Localized small scar may be treated by V-Y
operation
Large scar requires excision of scar tissue and
application of matching (whole or spilt) skin
graft
256. Ectropion
• Treatment
– Lubrication
– Horizontal lid shortening or tightening
– Punctal inversion
261. dermatochalasis
- excessive and lax eyelid skin and muscle is known as dermatochalasis. Gravity,
loss of elastic tissue in the skin, and weakening of the connective tissues of the
eyelid frequently contribute to this lax and redundant eyelid tissue. These
findings are more common in the upper eyelids but can be seen in the lower
eyelids as well.
- The patients who complain of dermatochalasis frequently complain of visual
difficulties
- Causes:
- The most common cause of dermatochalasis is the normal aging phenomenon
- Patients with severe periorbital edema may develop dermatochalasis
- Trauma can be associated with dermatochalasis
- Chronic dermatitis
- Thyroid eye disease
- Chronic renal insufficiency
- Amyloidosis
- Genetics may play a role in some patients who develop dermatochalasis
- Treatment:
- Blepharoplasty is the procedure of choice for upper and/or lower eyelid
dermatochalasis
262. ptosis
This is an abnormally low position of the upper eyelid.
PATHOGENESIS
It may be caused by:
Mechanical factors:
(a) Large lid lesions pulling down the lid.
(b) Lid oedema.
(c) Tethering of the lid by conjunctival scarring.
(d) Structural abnormalities including a disinsertion of
the aponeurosis of the levator muscle, usually in
elderly patients.
263. 2.Neurological factors:
(a)Third nerve palsy
(b)Horner’s syndrome, due to a sympathetic
nerve lesion
(c)Marcus–Gunn jaw-winking syndrome.
3.Myogenic factors:
(a)Myasthenia gravis
(b)Some forms of muscular dystrophy.
(c)Chronic external ophthalmoplegia.
264. SYMPTOMS
Patients present because:
they object to the cosmetic effect;
vision may be impaired;
there are symptoms and signs associated
with the underlying cause
(e.g. asymmetric pupils in Horner’s syndrome,
diplopia and reduced eye movements in a
third nerve palsy).
265. Ptosis
• Pseudoptosis
– Orbital volume deficiency
– Exophthalmos
– Excess lid skin
– Hypotropia
267. Ptosis
• Treatment
– Ptosis crutch
– Taping of the lid
– Surgical
• Levator advancement
• Muller’s muscle resection
• Frontalis suspension
268. Signs :
There is a reduction in size of the interpalpebral aperture.
The upper lid margin, which usually overlaps the upper
limbus by 1–2imm, may be partially covering the pupil.
The function of the levator muscle can be tested by
measuring the maximum travel of the upper lid from
upgaze to downgaze (normally 15–18imm). Pressure on
the brow (frontalis muscle) during this test will prevent its
contribution to lid elevation.
If myasthenia is suspected the ptosis should be observed
during repeated lid movement. Increasing ptosis after
repeated elevation and depression of the lid is suggestive
of myasthenia
269. MANAGMENT
It is important to exclude an underlying cause
whose treatment could resolve the problem
(e.g. myasthenia gravis). Ptosis otherwise
requires surgical correction
In very young children this is usually deferred
but may be expedited if pupil cover threatens
to induce amblyopia.
270. Ectropion
- Eversion of the lid away from the globe.
- Causes:-
-age related orbicularis muscle laxity.
-facial nerve palsy.
-scarring of periorbital skin.
- initial complaint of watery eye, because the mal
position of the lids everts the puncta and
prevents drainge of the tears leading to
epiphora(overflow of the tears over the cheeks )
-it also exposes the conjuctiva leading to irratable
eye.
- treatment: surgical
271. Ectropion
• Ectropion is out-rolling of lid margin
• Symptoms are:
Watering (due to eversion of punta)
Foreign body sensation
Pain
Redness
Photophobia (Due to involvement of cornea)
Symptoms are due to eversion of punta, and
exposure of ocular surface, chronic conjunctivitis
caused by exposure and drying of surface
272. Sequelae of Ulcerative Blepharitis
• Chronic course and associated chronic
conjunctivitis
• Madarosis (Scanty eyelashes) due to falling of
eyelashes
• Trichiasis (misdirected eyelashes) due to
contraction of scar tissue
• Cicatrization of lid margins causing thickening
and hypertrophy of tissue and drooping of lids
(Tylosis)
273. Sequelae of Ulcerative Blepharitis
• Cicatrization of lid margin may drag
conjunctiva on posterior border of
intermarginal strip disturbing angle of
posterior edge leading to epiphora , eversion
of puncta
• Epiphora leads to eczematous condition of
skin, scarring of skin leads to ectropion . This
further aggravate epiphora
274. Blepharitis
Blepharitis is an inflammation of the eyelids and occurs in two forms, anterior
(outside of the eyelid) and posterior (inner eyelid). Both types of blepharitis can
cause a burning or foreign body sensation, excessive tearing, itching, sensitivity to
light, red and swollen eyelids, redness of the eye, blurred vision, frothy tears, dry
eye, flaking at the base of the lashes, or crusting of the eyelashes upon awakening.
Common causes for anterior blepharitis are bacteria (Staphylococcus) and scalp
dandruff while posterior forms are caused by problems with the oil glands in the
eyelid. Treatment for both forms involves keeping eyelids clean and free of crusts.
Warm compresses should be applied to loosen crusts, followed by a light scrubbing
with a cotton swab and a mixture of water and baby shampoo.
Because blepharitis rarely goes away completely, most patients must maintain
an eyelid hygiene routine for life. If the blepharitis is severe, an eye-care
professional may also prescribe antibiotics or steroid eyedrops.
275. Posterior Blepharitis
• Posterior blepharitis i.e. inflammation of meibomian
duct opening at intermarginal strip and posterior
border may cause tear film instability and inferior
punctate keratitis
• It occurs in two clinical forms
a. Meibomian seborrhoea – characteristic
appearance of oil droplet at the opening of
meibomian duct opening at intermarginal strip. Tear
film is oily and foamy. Frothy discharge accumulate
on the lid margin. Foam like discharge can be
expressed from these lesions
276. Posterior Blepharitis
b. Meibomianitis – There is inflammation and
obstruction of meibomian glands.
Characterized by diffuse thickening of
posterior border of lid margin which becomes
rounded. On lid massage toothpaste like thick
material can be expressed out. Due to duct
blockade cyst formation may be present
278. Treatment
• Warm compresses
• Systemic - Doxycycline 100 mgm twice x 1
week then once daily for 6 -12 weeks or
Tetracycline 250 mgm 4 times x 1 week then
twice for 6 -12 weeks
• Associated tear film abnormality is treated
with artificial tear drops
279. Blepharitis
Inflammation of the eyelid margins.
It is a chronic disease.
Symptoms:
- tired, itchy, sore eye, worse in the morning.
- Crusting of the lid margin.
Classified into: anterior and posterior .
Both forms are strongly associated with
seborrhoeic dermatitis, atopic eczema and acne
rosacea.
280.
281. Anterior Blepharitis
Is when the inflammation is located in the outside surface
the lid margin, specifically in lash line.
Signs are:
-Redness and scaling of the lid margin.
-Debris in the form of a collarette around the eyelashes.
-Reduction in the number of eyelashes.
-Some lash bases may ulcerated- sign of staphylococcal
infection.
In severe diseasesthe cornea is affected (blepharokeratitis)
Small infiltrate ulcers may form in the peripheral cornea
(marginal teratitis)due to immune complex response to
staphlococcal exotoxins .
282. Posterior blepharitis
Have another name which is meibomian gland
dysunction.
Signs are:
- Obstruction and plugging of the meibomian
orifices.
- Thickened , cloudy, expressed meibomian
secretion.
- Injection of the lid margin and conjuctiva.
- Tear film abnormalities and punctate keratitis.
283.
284.
285. Treatment
Anterior blepharitis:
• Cleaning with a cotton bud wetted with bicarbonate or diluted baby
shampoo to remove squamous debris from lash line .
• Topical steroid: used infrequently.
• Topical (fusidic acid) +- systemic antibioticin staphylococcal lid
disease .
Posterior blepharitis:
• Hot compressors and lid massage.
• Oral tetracycline.
• Artificial tears to prevent dryness
288. Etiology
• Usually caused by staphylococcus aureus
• There is infection of hair follicle of eyelash.
• It may complicate Acne Vulgeris in young
adults.
290. Clinical Picture
• Stye are frequently recurrent, appearing in
crops.
• Recurrent lesion is particularly seen in cases of
debility, focal infections and diabetics.
291. Symptoms
• Severe pain which is sharp throbbing , feeling
of fullness or heaviness and feeling of heat
• Tenderness (increase in pain on touching
swelling/ affected area)
• Pain subsides on escape of pus
292. Signs
• Starts usually as edema
of the lids with
chemosis
• Yellow pus point
appears on the lid
margin around the root
of a lash at the most
prominent part of the
swelling
293. Signs … contd
• Skin gives way and pus
drains with sloughing
• Swelling subsides and
cicatrix form
• Spread of infection to
neighbouring lashes
opposite lid margin and
conjunctival sac
• Subsidence of inflammation
may leave area of
induration
295. Complications
• Cellulitis (particularly in cases of lesion at
inner canthus)
• Orbital thrombophebitis (leading to cavernous
sinus thrombosis and its complications)
296. Treatment
I. Systemic
a. Antibiotic
b. Anti-inflammatory analgesic
c. Supportive
d Treatment of associated systemic
predisposing cause
297. Treatment
II. Local
a. Hot fomentation
b. Local broad spectrum antibiotic drop and
ointment
c. Evacuation of pus when pus points,
sometimes epilation may be required before
evacuation of pus (lid margin/ lesion should
never be squeezed)
299. Hordeolum Internum
• Hordeolum Internum is a suppurative
inflammation of meibomian gland.
• It may be due to secondary infection of
meibomian gland or it may start to begin with
as suppurative infection of meibomian gland.
• This condition is more symptomatic than stye,
the gland is larger and is located in fibrous
tarsal plate
300. Symptoms
• Pain, which may be severe throbbing
• Swelling , which is away from lid margin
• Pus pointing either at the lid margin or on the
palpabral conjunctiva
301. Signs
• Swelling of affected lid, due to associated
cellulitis
• Swelling is more marked about 4-5 mm from
lid margin
• Tenderness
• Palpabral conjunctiva over the swelling is
congested a pus point may be visible
• Pus point may be visible at the lid margin
302. Treatment of Hordeolum Internum
• Medical treatment is similar to treatment of
Hordeoulm externum i.e.
Systemic
a. Antibiotic
b. Anti-inflammatory analgesic
Local
a. Hot fomentation
b. Local broad spectrum antibiotic drop and
ointment
303. Possible outcome of Treatment
• It may resolve with evacuation of pus at the lid
margin
• It may burst on palpabral conjunctiva, leading to
infective bacterial conjunctivitis and persistence of
growth on palpabral conjunctiva, resembling
papilloma. It due to fungating mass of granulation
tissue sprouting through opening. It causes irritation
and conjunctival discharge
• It turns into chronic granuloma i.e. Chalazion
304. Chalazion (Eyelid Cyst)
A chalazion is a tiny lump of the upper or lower eyelid caused by
inflammation of a gland of the lid. It may be soft and fluid-filled or firmer. A
chalazion is also referred to as a meibomian cyst, tarsal cyst, or conjunctival
granuloma.
The narrow opening through which a meibomian gland secretes its material
can become clogged from narrowing of the opening or hardening of the
sebaceous liquid near the opening. If this occurs, the gland will have a backup
of the material it secretes and it will swell.
Most chalazions are treated with warm compresses to the eyelid to promote
healing and circulation of blood to the inflamed area. Doctors may prescribe
an antibiotic drop or ointment to be used immediately after the compresses. If
the chalazion persists and is causing an unsightly lump, it can be removed
surgically through the inside of the lid.
306. Chalazion
• Chalazion is also called tarsal cyst or meibomian cyst
• Chalazion is chronic inflammatory inflammatory granuloma of
meibomian gland
• Seen in adults more often as multiple lesions occurring in
crops
• The glandular tissue is replaced by granulation tissue
consisting of gaint cells, polymorphonuclear cell, plasma cells
and histiocytes, indicating reaction to chronic irritation. The
opening of meibomian gland is occluded leading to retention
which acts as cause of chronic irritation
307. Chalazion
Symptoms:
Hard painless swelling little away from lid
margin
Swelling increases gradually in size without pain
Small chalazia are better felt than seen
Multiple lesions and large chalazion may be
associated with inability to open eye fully
308. Chalazion
• Signs:
Painless swelling 4-5 mm away from lid margin. Swelling is
hard
On conjunctival side it appears red or purple. In long standing
lesions it appears grey. In old lesion granulation tissue turns
into jelly-like mass.
Chalazion may become smaller over the period of time , but
complete resolution may occur only rarely
Sometimes the granulation tissue is formed in the duct and
project at the intermarginal strip as a reddish grey nodule
309. Treatment of Chalazion
• Intralesional injection of Triamcinolone
Acetonide may help in resolution of chalazion
• Incision & curette of chalazion is indicated in
cases when it causes disfigurement and
mechanical ptosis due to its weight
310. Steps of operation
• Explain about condition and operation
• Informed consent
• Topical anaesthesia and sub-muscular
infiltration of 2% Lignocaine
• Application of chalazion clamp around the
nodule (this will provide field for bloodless
operation, hard base and protect deeper soft
structures). Lid is everted
• Infiltration of lignocaine around swelling
312. Steps
• Vertical incision on most prominent point/
point of greatest discolouration with sharp
scalpel blade
• Semi-fluid/ cheesy contents are taken out
with small chalazion scoop (Curette)
• Pseudocapsule/ cavity is excised or the cavity
is cauterized with pure carbolic acid or
10-20% trichloracetic acid
313. Steps
• Clamp is removed, and pressure is applied on
lid to stop bleeding or pressure bandage is
applied for few hours
• Swelling remains for few days after surgery as
the cavity is filled by blood
• Post-operatively analgesic may be needed
systemically. Local antibiotic drop and
ointment for one to two weeks
314. Chalazion
• Very hard chalazion near canthi may be
adenoma of gland and requires excision
• Recurrent lesion particularly in elderly
patients should be investigated for meibomian
gland carcinoma (by biopsy)
