Q

Capillary Hemangioma
Complications
Management

A

Amblyopia due to refractive error or visual deprivation

Q

Epidermoid Cysts (Epidermal inclusion cyst)

  • What is it

A

Superficial cyst filled with keratin
Caused when surface skin cells move deeper into the skin and multiply, forming a wall. They secrete keratin which fills the cysts. Likely due to skin trauma.

A

Benign epidermal tumor that can develop anywhere on the skin. Typically between skin folds- neck, eyelids.

Proliferation of squamous epithelial cells overlying a fibrovascular core. Variable degrees of hyperkeratosis.
May be a response to viral infection (HPV)

Secondary open angle glaucoma due to pigment blocking TM

45
Q 
Oculodermal Melanocytosis (Nevus of Ota) 
Management
A

Monitor for glaucoma
-IOP, gonio, ON pics, ON OCT, GCC, VF

Monitor for melanoma- SL exam, A seg photos.

Symptomatic- refer out for laser therapy. May cause scarring. Hyperpigmentation may recur.

46
Q

Oculodermal Melanocytosis (Nevus of Ota) but only the sclera and urea are involved

A

Ocular Melanocystosis.

Same risk for glaucoma and transformation into uveal melanoma.

47

Typically bilateral, small patches of slate grey pigmentation.
Benign
Common in black and asians

  • Cause
A

Benign epidermal/dermal tumor that can occur anywhere on the skin.
Proliferation of melanocytes. Associated with UV exposure.

Junctional- Melanocytes clump at epidermal/dermal junction.

Compound- Melanocytes extend from epidermis to the dermis

Intradermal- Melanocytes clump within dermis. Most common.
