The authors reported clinical review of 85 cases of benign tumors of the eye and its adnexa diagnosed histopathologically for last 15 years at Department of Ophthalmology, Busan National University Hospital. The followings were summarized. 1. The occurence of benign tumors of the eye and its adnexa by age was frequent under 3rd decade but no sexual differences were found. 2. The benign tumors in the eye and its adnexa were frequently involved eye lids (33 cases, 38.8%), orbit (25 cases, 29.4%) and conjunctiva (19 cases, 22.4%) in erder. 3. The frequency of occurence of benign tumors in the eye and its adnexa was dermoid cyst (18 cases, 21.2%), hemangioma (12 cases, 14.1%), cysticercosis and nevus (9 cases, 10.6% in each) and pseudotumor (5 cases, 5.9 %) in order. In addition, 3 rare benign tumors in the ocular adnexa, such as an epibulbar osseous choristoma in the subconjunctiva, a benign mixed tumor originated from medial canthal eccrine gland and hemangioendothelioma located in the eye lid were presented.

Ultrasonograms were obtained from 27 cases of intraocular and 10 cases of orbital diseases with S.K.L containing a general transducer(A-mode), 1~3 MHz in its frequency and 15mm in its diameter. The authors summerized that these ultrasonograms would provide some benefits in supplementary clinical diagnosis, especially in confirming the presence of intraocular tumors, differential diagnosis of primary and secondary retinal detachment and deciding the location and surgical procedure preoperatively in the orbital tumors.

We electron-microscopically studied 15 specimens of upper limbal conjunctiva obtained from 14 patients with exfoliation syndrome and clinical evidence of glaucoma. Of 15 specimens, four(three patients) contained exfoliation materials in the stroma of the stroma of the conjunctiva. These exfoliation materials of immature, intermediate, and mature forms were composed of abnormal microfibrils lying adjacent to the fibroblasts and located in close proximity to the elastic and collagen fibers. These observations suggest a sequence of events by which microfibrils develop into exfoliation materials.

The authors observed retinal vascular patterns of the blind eyes surgically removed on account of pain, high intraocular pressure and global rupture by injury. Material for the study was 10 eyes which were 4 eyes of long standing absolute glaucoma, late stage of chronic simple glaucoma (3 eyes) and chronic angle closure glaucoma (1 eye). aphakic glaucoma (1 eye) and an eye of chronic simple glaucoma with traumatic global rupture. The technique of preparation of the slides was made of flat preparations of retinal vessels that all nonvascular components were digested with tris-buffered 3% trypsin solution and stained with PAS-hematoxylin and Wilder's reticulin stain. RESULTS OBTAINED AS FOLLOWS; 1. it is possible that diffuse acellularity (predominant loss of endothelium) in the capillaries of the equatorial and posterior portion of retina results from the arterial occlusion. 2. Solitary microaneurysm in the peripheral retinal capillary was found in the early stage and numerous saccular and fusiform aneurysms (rows of bead-like aneurysms) on the venules, and arteriolar and venular capillaries are related to the degree and duration of the venous occlusion. 3. The majority have had venous occlusion initially, on which distal venule there are found rows of bead-like outpouchings, and the occlusive arterioles show fibrinous appearence, accllularity and increasing PAS staining. 4. It is possible that abnormal A-V shunts and venous collaterals result from the venous occlusion and rows of bead-like microaneuysms in the capillaries will be switched over to shunts and collaterals.

The authors report the result of cryo-extraction of the lens in 50 eyes (44 cases) which were operated in B.N.D. Hospital from January 1978 to April 1980. The results are as follows: 1. The incidences of complication during operation were hyphema(8%), vitreous loss and rupture of the lens capsule(2%). Hyphema was the most common complication during operation. 2. The incidences of early postoperative complication were striate keratitis(26%), hyphema (2%), shallow anterior chamber(2%) and uveitis. 3. The incidences of late postoperative complication were vitreous prolapse into anterior chamber (6%), updrawn pupil(6%), macular edema(4%) and posterior synechia (2%), corneal degeneration with abnormal tissue growth into anterior chamber (2%), iris atrophy (2%) and vitreous opacity (2%). 4. The postoperative final visual acuity more than 0.5 were 37 eyes(74%) and less than 0.1 were 2 eyes(4%).

The authors studied the retinal vascular patterns of human eye suffered from complicated endophthalmitis following by perforating injury and corneal ulcer. The technique of preparing slides to study the retinal vascular patterns were same as previously noted Part I report. A lot of microorganisms, such as cocci, bacilli and fungi are found in the inflamed foci(with or without filaments) around the retinal vessels unless the vessels were completely occluded. Focal and diffuse exudative vasculitis is related to the species of microorganisms and cbserved stage but almost all retinal vessel waIls show diffuse loss of perivascular argyrophilic fibers, socalled "moth eaten" appearance. In the later stage of vasculitis microorganisms are not found in the inflamed focus("punched out" lesion) of the occluded vessels which show as "bark-stripped-dead tree" appearance in reticulin stain.

Prirnary sclerosing cholangitis, a chronic progressive cholestatic hepatobiliary disorder of unknown etiology, is characterized by inflammation, scarring and obliteration of bile duct leading to biliary cirrhosis and liver failure. Because histologic finding has only a limited role in the diagnosis, the gold standard for establishing the diagnosis is cholangiographic demonstration of typical diffuse biliary stricutre or beading. The natural history is extremely variable. We report two cases of primary sclerosing cholangitis diagnosed by repeated endoscopic retrograde cholangiographies. They were followed up for 7 and 2 years, respectively.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography(ERCP) or operative cholangiography is the procedure to demonstrate and remove stones of the biliary tree in patients undergoing laparoscopic cholecystectomy(LC) due to cholelithiasis. However, ERCP or operative cholangiography is an invasive procedure. The next question then is when and for what indication should ERCP or operative cholangiography be performed. The aims of this study were to assess whether prediction of common bile duct(CBD) stones by the noninvasive method such as liver function test and/or clinical findings is possible, and to investigate which method is more adequate for removal of CBD stones found on ERCP or operative cholangiography. METHODS: A total 207 patients with symptomatic cholelithiasis scheduled for LC were enrolled from September 1993 to August 1996. Patients who were already found to have either extrahepatic or intrahepatic biliary stones on sonogram were excluded. Patients were classified into risk group and non-risk group. Patients who belong to the risk group were those having CBD dilatation by ultrasonography, history of jaundice or cholangitis, gallstone pancreatitis, or elevated transaminases. RESULTS: 54 cases were confirmed to have CBD stones by preoperative ERCP(49 cases) and operative cholangiography(5 cases). Detection rate of CBD stones in risk group was 26.8%(22.2% in CBD dilatation, 50.0% in jaundice, 42.9% in history of cholangitis, and 0% in history gallstone pancreatitis or elevated transaminase). Detection rate of CBD stones in non-risk group was 7.7%. All of 12 patients who had CBD stones were successfully removed(10 with preoperative endoscopic removal, 1 with postoperative endoscopic removal, and 1 with CBD exploration). CONCLUSIONS: Jaundice or cholangitis need the preoperative ERCP and, if stones are found, they can be revoved endoscopically. CBD dilatation may be an indication for operative cholangiography rather than preoperative ERCP, and, if CBD stones were found, they can be revoved by laparoscopic CBD exploration or postoperative ERCP. But history of gallstone pancreatitis, elevated transaminases, or patients with no risk factors may not need preoperative ERCP or operative cholangiography considering the cost-effectiveness or possible morbidity.

An association of hepatolithiasis and cholangiocarcinoma is thought to be rare, with a rate reported to be 2.36%-10%. Most of the cholangiocarcinomas concurrent with intrahepatic stones are found in the vicinity of the hepatolithiasis, and the diagnosis of intrahepatic cholangiocarcinoma in cases with hepatolithiasis is very difficult to detect preoperatively in spite of recent developments in techniques of imaging studies. Recently, the development of cholangiocarcinoma was reportd even after the complete removal of the hepatic stones. Thus, bile stasis and bacterial infecton appear to be important causative factors causing cholangiocarcinoma rather than the stone itself. A rare case is reported on intrahepatic cholangiocarcinoma developed in a remote region from the site of the hepatolithiasis. Therefore, the possible presence of cholangiocarcinoma should always be considered and sought during the diagnosis and treatment of hepatolithiasis.
