True or False. Primary melanomas of the eyelid skin are extremely rare.
Diseases that increase orbital contents therefore displace the eye forward, a condition known as __________ .
Which neoplasm of the eyelid is going to have a tendency to metastasize and is therefore a serious and potentially life-threatening condition?
Infection with __________ may produce significant conjunctival scarring.
Malignant neoplasms arising in the eyelid and conjunctiva tend to spread to ________ and ______ Lymph nodes.
_________ is the part of the conjunctiva that contains a lot of lymphatics.
Pinguecula and pterygium appear as submucosal elevations on the conjunctiva. Which one is going to typically originate in the conjunctiva astride the limbus?
Which one will not penetrate the cornea and shows up as a small, yellowish submucosal elevation?
Which structure is the major refractive surface of the eye?
Cornea (NOT the lens)
________ is an example of a condition that destroys the contour of the cornea and alters its refractive surface.
Corneal dystrophies are typically _________, while corneal degenerations are typically ________ .
2. Not inherited
Describe the anatomy of the anterior segment.
The anterior chamber is bound anteriorly by the cornea, laterally by the trabecular meshwork and porsteriorly by the iris
________ describes lenticular opacities that may be congenital or acquired.
Which part of the eye is going to contain cataracts?
Advanced age, smoking, sun exposure, atopic dermatitis, Diabetes mellitus, Wilson disease, Galactosemia and certain drugs are all risk factors for ___________ .
Age, Race, Family History, Diabetes, Trauma, Prolonged corticosteroid use and eye abnormalities are all risk factors for __________ .
In ___________ , the aqueous humor has complete physical access to the trabecular meshwork, and the elevation in intraocular pressure results from an increased resistance to aqueous outflow.
In _______. the peripheral zone of the iris adheres to the trabecular meshwork and physically impedes the egress of aqueous humor from the eye.
__________ glaucoma typically develops in eyes with shallow anterior chambers, often found in individuals with hyperopia.
__________ glaucoma has many causes.
_______ is an example of a systemic condition that may produce granulomatous uveitis and sympathetic opthalmia may produce bilateral granulomatous inflammation as a possible consequence of penetrating injury to one eye.

3. Ciliary Body
__________ retinal detachment is associated with a full-thickness retinal defect.
_________ is retinal detachment without a retinal break.
Malignant Hypertension and Choroidal tumors are examples of _________ retinal detachment.
In ________, blood vessels in the eye may appear narrowed, and the color of the blood column may change from bright red to copper and to silver depending on the degree of vascular wall thickness.
