Dermoid

- Smoothy fleshy, cystic tumor

- Made up of hair, skin, teeth,

- Remove if it block the cornea and causes irritation and poor wetting

Dermoids are usually found in the

Lateral Canthus

Unilateral

Isolated

Dermoid can Cause Dellen

Thinning of the Cornea adjacent to a raised lesion causing bridging of the eyelid

Does not stain well with Fl

How to differentiate a dermoid from an ulcer

Dermoids dont stain with FL

Pinguecula

- Yellow Nodule of hyaline-elastic tissue

- Does not involve cornea

- Usually bilateral

- Usually leads to pterygium or Pingueculitis

Treat Piguecula with

Mild - lubricants, decongestants

Moderate - NSAIDs (itis)

Hot - site specific steroids

Pterygium

- Thin transperent fold of fibrovascular conj tissue over the cornea epithelium and bowmans membrane

- Usually occurs nasally

In Pterygium _______________ becomes______________

Vascularized Conj Epithelium

Becomes

Corneal Epithelium

Psuedopterygium

Ulcer on the limbus, the conj will grow towards the ulcer

Sequella of trauma or burn

When to do surgery for Pterygium

Halfway between the limbus and pupilary border

Beta irradiation with strontium 90 decreases reoccurrence

Conjunctival Concretions

- Calcium deposits, yellowish-white particles, like grains of salt.

- May require lube or removal if irritation

- Found in the fornix and cul-de-sac

Conjunctival Papilloma

Benign, Abnormal Epithelial Grown

Not a Cyst

Pyogenic Granuloma

- Not an inflammation but the result of inflammation

- Granulamatous growh

- Usually on Palp conj

- Must be removed to make sure its granuloma

Telengiectasia

- Dialation of Conjunctival vessels

- Swirl like appearance - spider veins

- NOT neovscularization

Hemangioma

Benign Conjunctival Blood Tumor

Non-Pigmented Tumors of the Conjunctiva

- Dyskeratosis

- Conjunctival Papilloma

- Lymphagiectasis

- Ademona

- Neurofibroma

Dyskeratosis

- V-shaped translucent lesion by the limbus

- Not malignant, elevated, or symetrical

- When in doubt take a picture

Conjunctival Papilloma

- Arises from conjunctival mucous membrane

- If irritation you can remove

- Not imflamed

- Very little vascularization

Lymphangiectasis

- Looks like water blister

- Found during allergy season

- Clear localized Cysts

- DIALTED LYMPH VESSLES

Malignant Tumors on Conj

Bowmans Disease

Squamous Cell Carcinoma

Kaposi Sarcoma

Bowmans Disease

- Cancer Cells that have yet to organize into a tumor

- Very Rare, more common in old

- Irregular Surface

- Large feeder vessels

Squamous cell carcinoma

- Epitheloma

- Can metastasize

- Large feeder vessels

- May be mistaken for CL over wear,

Kaposi Sarcoma

- Nodular Diffuse lessions

- Common in AIDs

Pigment Abnormalities

- Freckles

- Nevi

- Congenital Melanosis

- Aquired Melanosis

- Malignant Melanomas

Exogenous Black Deposits

- Discreate black deposits due to prolonged use of epinephrine

- GLC px and Eye liner use

Benign Melanosis

- Concentration of pigment cell by the perilimbal plica

- More common in blacks

- Salt and pepper look

- R/O malignant melanoma, and dont need to do anythin

Acquired Melanosis

- need to know where its coming from, trauma, injury or infection

- Shows up in 40s

Nevus

- Pre-cancerous mole

- Cystic appearance

- Need to do excision to be safe

Malignant Melanoma

- Elevated area that grows rapidly

- Leading cause of death with skin cancer

- Seen in 40-60s

- Rapid diagnosis and aggressive treatment

Belpharochalasis

- Rare Autoimmune condition

- Loss of tone and stretch to lids due to constant edema around the eye lids

- Seen in young people

- Treat with blepharoplasty

Dermatochalasis

- Loss of tension in the lids

- And herniation of orbital fat through the orbital septum

- Aging process and is bilateral

- Look for px with raised eyebrows and treat with blepharoplasty

Entropion

- Most common cause aging

- Rolling of the lid into the margins (irritating lashes)

Distichiasis

Additional row of lashes

- Accessory cilia grow from meibomian gland orfice

- Treat with bandage cl

- Surgery - crypoepilation

Trichiasis

Inward turning of lashes

-Sequella of chronic blepharitis

- Chronic FB, scratchy, mild abrasions

- Treat by epilation
