Condition/keywords: Morgagni's cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Morgagnian cataract. Clinical picture shows the nucleus floating in a bag of water.

Condition/keywords: Morgagni's cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Senile cataract (trichrome stain x 16). A hypermature lens is shown with a dense nucleus, an almost liquified cortex, and a wrinkled capsule. Some of the fluid has been lost (Scheie Eye Institute, No. 1596.)

Condition/keywords: hypermature lens, senile cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Posterior subcapsular cataract. Histologic section through the posterior pole of the lens, showing large bladder cells (x40). (Scheie Eye Institute, No. 34042.)

Condition/keywords: posterior subcapsular cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Posterior subcapsular cataract secondary to retinitis pigmentosa ( x40). (Scheie Eye Institute, No. 3968.)

Condition/keywords: posterior subcapsular cataract, retinitis pigmentosa

Feb 26 2019 by Lancaster Course in Ophthalmology

Anterior subcapsular cataract. Plaque of tissue beneath the anterior capsule replacing epithelium (PAS x21).

Condition/keywords: anterior subcapsular polar cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Anterior subcapsular cataract. The tissue stains as collagen. This pro­cess is an example of metaplasia of epithelial cells to connective tissue cells (trichrome stain x28). (Scheie Eye Institute, No. 5753.)

Condition/keywords: anterior subcapsular polar cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Anterior subcapsular cataract associated with severe inflammation of the anterior segment and an inflammatory pupillary membrane ( x40). (Scheie Eye Institute, No. 3952.)

Condition/keywords: anterior subcapsular polar cataract, pupillary membranes

Feb 26 2019 by Lancaster Course in Ophthalmology

Anterior subcapsular cataract associated with morgagnian degenera­tion of the underlying cortex ( x 40). (Scheie Eye Institute, No. 4076.)

Condition/keywords: anterior subcapsular polar cataract, Morgagni's cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Regeneration cataract with Elschnig's pearls ( X 16). Similar bladder cells (Wedl cells) are seen beneath the posterior capsule in a posterior subcapsular cataract. These are found after extracapsular extraction. (Scheie Eye Institute, No. 4083.)

Condition/keywords: cataract, Elschnig's spots, Wedl cells

Feb 26 2019 by Lancaster Course in Ophthalmology

Soemmering ring cataract ( x 16). The other limb would be found be­neath the iris on the opposite side. Adhesions of the iris to the regenerating lens protein have led to iris born be and closure of the anterior chamber angle. (Scheie Eye Institute, No. 4083.)

Condition/keywords: Soemmering's ring

Feb 26 2019 by Lancaster Course in Ophthalmology

Angle-closure glaucoma produced by pupillary block in an eye with an intumescent cataract. Gross appearance.

Condition/keywords: angle-closure glaucoma interval, cataract

Feb 26 2019 by Lancaster Course in Ophthalmology

Angle-closure glaucoma. Histologic section ( x 16). The lens is exces­sively large and presses against the pupil, resulting in pupillary block, iris bombe, and angle closure. (Scheie Eye Institute, No. 5879.)

Condition/keywords: angle-closure glaucoma interval

Pseudoexfoliation of the lens capsule. Clinical appearance of an ab­normal deposit on the surface of the lens. (Courtesy of H. G. Scheie, M.D.)

Condition/keywords: pseudoexfoliation syndrome

Feb 26 2019 by Lancaster Course in Ophthalmology

Pseudoexfoliation of the lens capsule. Central lens capsule (PAS x252).

Condition/keywords: pseudoexfoliation syndrome

Feb 26 2019 by Lancaster Course in Ophthalmology

Pseudoexfoliation of the lens capsule. Peripheral lens capsule (PAS x252).

Condition/keywords: pseudoexfoliation syndrome

Feb 26 2019 by Lancaster Course in Ophthalmology

Pseudoexfoliation of the lens capsule showing deposition of snowflake material on the vitreous face in an aphakic eye. The material has continued to accu­mulate, suggesting that it is an abnormal basement membrane from epithelium other than the lens epithelium.

Condition/keywords: aphakic eye, pseudoexfoliation syndrome

Feb 26 2019 by Lancaster Course in Ophthalmology

Phacolytic glaucoma. Clinical picture shows the anterior chamber filled with a milky lens cortex. A small hemorrhage is also present.

Condition/keywords: hemorrhage, phacolytic glaucoma

Morgagnian cataract after removal from the eye shown in Slide 10-21.

Condition/keywords: Morgagni's cataract

Condition/keywords: phacolytic glaucoma

Feb 26 2019 by Lancaster Course in Ophthalmology

Condition/keywords: epithelium, phacolytic glaucoma

Feb 26 2019 by Lancaster Course in Ophthalmology

Phacoanaphylactic endophthalmitis ( x 16). This eye was punctured by a knitting needle 3 weeks before enucleation. The area of inflammation is limited and the eye might have been saved had the cataract been removed. (Scheie Eye Institute, No. 1294.)
