Keratoconus is a non-inflammatory, progressive thinning and protrusion of the cornea that results in irregular astigmatism and decreased vision. It typically presents after puberty with no gender or racial predilection. Diagnosis is made based on corneal thinning, Fleischer ring, Vogt's striae, and irregular astigmatism seen on keratometry and topography. Mild cases are managed with spectacles while more severe cases require rigid gas permeable contact lenses, Intacs, or corneal transplantation.
This document discusses dry eyes, also known as aqueous tear deficiency. It defines dry eyes as a non-infectious ocular surface disorder caused by a lack of tear fluid. The three layers of the normal tear film are described: the lipid layer from meibomian glands, the aqueous layer from lacrimal glands, and the mucin layer from goblet cells. Various causes of dry eyes are classified, including deficiencies in the aqueous, lipid, or mucin layers. Signs, symptoms, and diagnostic tests are outlined. Management involves tear supplementation, preservation, treatment of underlying conditions, punctal plugs, anti-inflammatories, and surgery in severe cases.
Peripheral corneal diseases can be congenital, inflammatory, degenerative or neoplastic. Rheumatoid arthritis commonly causes peripheral keratitis like marginal keratitis and phlyctenular keratoconjunctivitis due to rheumatoid vasculitis affecting peripheral cornea. Wegener's granulomatosis can also involve peripheral cornea with necrotizing scleritis and peripheral keratitis. Treatment involves controlling the underlying systemic disease with immunosuppressants and managing ocular inflammation with corticosteroids.
Keratoconus is a progressive thinning disorder of the cornea that causes it to take on a conical shape and leads to irregular astigmatism. It was first described in the 1700s but was named keratoconus in 1869. The exact cause is unknown but genetic and environmental factors are thought to play a role. Asians have a higher incidence possibly due to consanguineous marriages. Symptoms include blurred vision and photophobia. Signs include corneal thinning, scissoring on retinoscopy, Fleischer's ring, and Vogt's striae seen on slit lamp. Diagnosis involves topography showing inferior steepening and uneven ring spacing on photokeratoscopy.

- Symptoms include burning, grittiness, dryness, and worsening in the morning. Signs include scales, debris, hyp
This document summarizes different types of lesions associated with abnormal dyskeratosis. It describes two main types: benign and malignant dyskeratosis. Under benign dyskeratosis it discusses hereditary benign intraepithelial dyskeratosis, dyskeratosis congenita, keratoacanthoma, Darrier's disease, and warty dyskeratoma. For malignant dyskeratosis it notes it can be found in premalignant conditions like leukoplakia. It provides details on the clinical features, histopathology, treatment and prognosis for each condition.
Dry eye is a common disease caused by insufficient tear production or increased tear evaporation. It affects 10-15% of the population and prevalence is higher in females and older individuals. The tear film consists of an outer lipid layer, middle aqueous layer, and inner mucus layer which together form a smooth optical surface and nourish the cornea. Dry eye is diagnosed based on symptoms, tear film breakup time, Schirmer's test, and ocular surface staining. Treatment involves artificial tears, punctal plugs, anti-inflammatories, and managing underlying conditions. Advanced cases may require punctal occlusion, contact lenses, or autologous serum tears.
This document discusses ocular involvement in leprosy. It notes that 70-75% of leprosy patients experience ocular involvement, with 10-50% experiencing severe symptoms and 5% becoming blind. The major parts of the eye affected include the eyelids, cornea, iris, ciliary body, conjunctiva, and nerves. Common complications include blepharochalasis, madarosis, trichiasis, lagophthalmos, dacryocystitis, punctate keratitis, pannus, iridocyclitis, glaucoma, and cataract. Modes of infection include direct invasion via blood or nerves. Management involves antibiotics, steroids, surgery, and
This document discusses several metabolic keratopathies and congenital anomalies of the cornea and globe. It describes cystinosis, mucopolysaccharidoses, Wilson's disease, and other lysosomal storage disorders that can cause corneal deposition and opacification. It also covers microcornea, microphthalmos, nanophthalmos, anophthalmos, and megalocornea - congenital anomalies where the cornea and/or globe are abnormally small or large. Complications, clinical features, inheritance patterns and treatment approaches are provided for each condition.
Pathological myopia, also known as degenerative myopia, is a vision condition characterized by excessive elongation of the eyeball and degenerative changes to the retina and choroid. It is most commonly caused by high amounts of near work like reading combined with a genetic predisposition. Complications can include retinal detachment, cataract, hemorrhage, and vision loss from conditions such as macular atrophy. Treatment focuses on slowing progression with low-dose atropine and managing complications through regular screening.

Thyroid eye disease (TED), also known as Graves' ophthalmopathy, is an autoimmune condition that affects the eyes and eyelids. It is commonly seen in patients with thyroid disease. The presentation can range from mild eyelid retraction to severe proptosis and optic neuropathy. The pathophysiology involves autoantibodies activating orbital fibroblasts and infiltrating lymphocytes, leading to inflammation and deposition of glycosaminoglycans in orbital tissues. Risk factors include smoking, female sex, and radioiodine treatment for hyperthyroidism. Clinical features depend on the stage of disease and can include dry eyes, eyelid swelling, proptosis, diplopia, and optic neuropathy. Classification systems consider soft tissue
Nasolacrimal duct obstruction can be congenital or acquired. It results in a blockage of the lacrimal drainage system which transports tears from the eye to the nose. The document describes the anatomy of the lacrimal drainage system and classifications of NLDO. Causes include infections, inflammation, tumors, trauma, and mechanical obstruction. Diagnosis involves history, examination, Jones dye testing, and imaging. Treatment depends on the type and includes massage, probing, dacryocystorhinostomy, and occasionally intubation or stenting. Surgical treatment aims to re-establish drainage from the lacrimal sac into the nose.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

3. INTRODUCTION/DEFINITION
• Blepharitis is an inflammatory condition of the
eyelid margin
• common cause of ocular discomfort and irritation
in all age and ethnic groups
• generally not sight-threatening, but can lead to
permanent alterations in the eyelid margin or
vision loss
4. BRIEF ANATOMY OF THE LID
MARGIN
• It is about 2mm broad and divided into 2 parts by the
punctum(medial and lateral)
• Lacrimal portion(medial)- is devoid of lashes
• Ciliary portion (lateral)- consists of rounded anterior border
and sharp posterior border with an intermarginal strip
between them (the 2 borders)
• The grey line divides the intermarginal strip into
• Anterior strip bearing 2-3 rows of lashes
• Posterior strip on which openings of the meibomian
glands are arranged in a row
• SPLITTING OF THE EYELID IS DONE AT THE GREY LINE IN
SURGERIES
9. • staphylococcal blepharitis may be an abnormal cell-
mediated response to components of the cell wall
of S. aureus, which may also be responsible for the
red eyes and peripheral corneal infiltrates
• More common and marked in patients with atopic
dermatitis.
• Seborrhoeic blepharitis is strongly associated with
generalized seborrhoeic dermatitis that
characteristically involves the scalp, nasolabial
folds, skin behind the ears and the sternum.
11. EPIDEMIOLOGY
• FREQUECY; Common eye disorder worldwide. 86% of
patient with dry eye have concomitant blepharitis
• Mortality/Morbidity; loss of visual function, well-being,
and ability to carry out daily life activities.
• lids with trichiasis, notching, entropion, and
ectropion.
• Corneal scaring, irregularity(astigmatism),
perforation
• mortality, such as in systemic lupus erythematosus,
may have blepharitis as part of their constellation of
findings
12. Epidemiology; Race
• No known studies demonstrate racial differences in
the incidence, of blepharitis, although Rosacea may
be more common in fair-skinned individuals
13. EPIDEMIOLOGY contd
• SEX:
• no difference in incidence
• Age
• Seborrheic blepharitis is more common in an older
age group. The apparent mean age is 50 years.
14. Pathophysiology
. The exact pathogenesis of blepharitis is unknown,
but suspected to be multifactorial.
. bacterial colonizes the eyelids.
. direct microbial invasion of tissues, immune
system–mediated damage, or damage caused by the
production of bacterial toxins, waste products, and
enzymes.
. Colonization of the lid margin is increased in the
presence of seborrheic dermatitis or meibomian
gland dysfunction
15. PATHOPHYSIOLOGY CONTD
• Meibomian gland dysfunction
• functional abnormalities of the meibomian
glands and altered secretion of meibum (slows
evaporation of tear film and smoothing the tear
film to provide an even optical surfa)
• Both quantitative and quantitative deficiencies in
meibum contributes to symptoms in MGD
blepharitis.
16. PATHOPHYSIOLOGY CONTD
• Bacterial lipases may result in the formation of free fatty acids.
This increases the melting point of the meibum, preventing its
expression from the glands, contributing to ocular surface
irritation and possibly enabling growth of S.
• MGD leads to meibomian waxlike secretions and blockage of
gland orificees
• Stagnant material becomes a growth medium for bacteria
• deeper eyelid tissue layers become affected causing
inflammation.
• Leads to M gland plugging, inspissated lipid secretory material,
inflamed orifices, and formation of hordeola and chalazia.
17. RISK FACTORS
• Dry Eye
• present in 50% of patients with staphylococcal
blepharitis. ; a decrease in local lysozyme and
immunoglobulin levels associated with tear deficiency
may alter resistance to bacteria, predisposing patients
to the development of staphylococcal
• 25% to 40% of patients with seborrheic blepharitis and
MGD also have dry eye.; may result from increased
tear film evaporation due to a deficiency in the lipid
component of the tears as well as reduced ocular
surface sensation.[4]
18. RISK FACTORS-DERMATOLOGICAL
CONDITIONS
• Acne rosacea
• has been reported in 20% to 42% of patients with
all types of blepharitis
• Characterized by facial skin erythema,
telangiectasias, papules, pustules, and prominent
sebaceous glands.
• Seborrheic dermatitis, characterized by flaking and
greasy skin on the scalp, retroauricular area,
glabella, and nasolabial folds,--reported in 33% to
46% of patients with blepharitis

• inflammatory response
• Demodex folliculorum longus in anterior blepharitis
and Demodex folliculorum brevis in posterior
blepharitis
