APRIL 2010 I CATARACT & REFRACTIVE SURGERY TODAY EUROPE I 31 T he incidence of wound gape or iris prolapse after cataract extraction reportedly ranges from 0% to 1.6% with phacoemulsification and 0% to 3% with extracapsular cataract extraction.1 Contemporary cataract surgery is most commonly performed through sutureless clear corneal incisions with a wound width of 3.2 mm or less. These small w...

We report an unusual case of iris rubeosis and hyphema caused by chemical injury due to household detergent. A 74-year-old man with a 15-year history of diabetes mellitus was refilling a container with household detergent at home. He splashed the detergent in his eyes. Slit-lamp examination revealed extensive epithelial damage to the left eye, leading to a persistent corneal epithelial defect. ...

Cystic disease of the spleen is a relatively rare disease. It is classified either as a true primary cyst or as a secondary pseudocyst. Most splenic cysts are pseudocysts, which have non-epithelial lining, and are caused by previous abdominal blunt trauma. Conversely, primary splenic cysts have epithelial lining and are subdivided into parasitic and non-parasitic cyst. Non-parasitic primary spl...

Cysts, a common abnormality of kidneys, are collections of urine-like fluid enclosed by a continuous layer of epithelial cells. Renal cysts derive from nephrons and collecting ducts and progressively enlarge as a consequence of epithelial proliferation and transepithelial fluid secretion. The initiation of cyst formation and the factors that control cyst enlargement are unknown. We used an in v...

I In continuation of an electron microscopic study of pseudo-exfoliation of the lens capsule, this paper reports the changes found in the iris and ciliary body. The possible significance of all findings in the investigation are then discussed. The deposition of exfoliative material occurs predominantly in the posterior chamber and was found in the internal limiting membranes of the iris and cil...

The patient was a 72-year-old man with a mass in his right axilla for 1 year. The tumor was painless, mobile, and slowly increasing in size; at its largest it measured 3 cm in diameter and was in a subcutaneous location. The clinical presumptive diagnosis was epidermoid cyst, mucocele, adnexial tumor, and nodule. The lesion was excised under local anesthesia. The resected specimen consisted of ...

1. A strain of pure epithelial cells was obtained from the part of the iris which adheres to the extirpated lens. 2. The optimum condition under which epithelial cells grow in vitro is on the free surface of the plasma clot under a film of embryonic tissue juice. 3. The epithelial cells did not dedifferentiate. Although the strain is 3 months old, they grow as a pavement membrane and have kept ...

Odontogenic cysts are pathological cavities enclosed by fibrous connective tissue and lined with epithelial that develops from odontogenic tissues in the maxilla mandible's tooth-bearing regions. Trauma or tooth caries is main cause of radicular periapical cysts. Pulp necrosis outcome dental irritating pulp cavity. Once infection has reached root's tip, it causes periodontitis, which may lead t...

Renal cyst enlargement is increased by adenosine cAMP, which is produced within mural epithelial cells. In a search for modulators of cAMP synthesis cyst fluids from 18 patients with autosomal dominant or recessive polycystic kidney disease (PKD) were analyzed, and in 15 of them, a stable lipophilic molecule that increased cAMP levels, stimulated transepithelial chloride and fluid secretion, an...
