[Heterochromia complicata Fuchs, crystalline iridopathy and increased immunoglobulin G in aqueous humor. A case report].

We report on a 35 year old patient suffering from heterochromia complicata Fuchs with a mature cataract. Multiple small whitish-yellowish crystal-lines on the iris at the 7 and 12 o'clock position were interpreted as Russell bodies and correlated with an elevated concentration of 7.2 mg/dl IgG in the aqueous humor analysis. IgA und IgM could not be detected (less than 1.1 mg/dl). Three months after an unremarkable extracapsular cataract extraction and posterior chamber lens implantation a positive Tyndall phenomenon and Russell bodies were found at just the same locations on the iris.

Blood velocity in the ophthalmic artery in normal subjects and patients with endophthalmitis.

Some ocular diseases lead to temporary changes in the ocular blood circulation. This study was undertaken to evaluate changes in the blood-flow velocity of the ophthalmic artery in patients with endophthalmitis. With pulsed Doppler sonography the blood velocity of the ophthalmic artery was measured in 50 normal subjects and in ten patients with bacterial endophthalmitis. In normal subjects blood velocity decreased with increasing age, and the average systolic/diastolic blood velocity in cm/sec were 38.8 +/- 6.3/11.6 +/- 4.7 in the 18-50-year-old age group and 28.3 +/- 4.6/6.7 +/- 3.3 in the 51-88-year-old age group. Endophthalmitis produced increased systolic/diastolic blood velocity in the ophthalmic artery in the affected eyes in cm/sec (99.7 +/- 15.5/26.6 +/- 10.5 in the 16-50-year-old age group; 60.4 +/- 8.8/16.6 +/- 4.8 in the 51-83-year-old age group). Some patients showed similar changes in the unaffected fellow eyes. The noted elevation of the blood velocity in unaffected eyes may be due to the bilaterally projected parasympathetic fibers of the oculomotor nerve.

[Blood flow velocity in the ophthalmic artery measured using transbulbar Doppler sonography].

Blood-flow velocity in the ophthalmic artery was examined at different orbital depths by pulsed ultrasound (4 MHz). Blood-flow velocity was influenced by patient age and showed a decrease in the vicinity of the eye. Forty-one normal subjects had an average systolic and diastolic blood-flow velocity of 36.5 and 10.9 cm/s at a 36 mm depth.

[Retained cholelithiasis--a risk factor after endoscopic papillotomy?].

Endoscopic papillotomy (EPT) today is in well defined indications an accepted procedure for the therapy of common bile duct stones. In patients with stone gallbladder in situ and bile duct stones it has been recommended to remove the gallbladder after papillotomy in order to prevent late complications. The present study shows that the gallbladder in situ is not necessarily a significant risk factor. On an average of 34,9 months (16-84) after EPT of 223 patients with a follow up, 83,7% were free of symptoms or significantly improved. Cholecystectomy was performed in 43 patients (18,9%): in 24 (11,6%) within an interval , in 13 (6,3%) as an emergency operation following a complication of EPT and in 2 (1%) months later because of recurrent cholecystitis. In patients over 70 years of age with increased risk for surgery therefore a gallbladder with stones after EPT must not absolutely be removed. A wait and see attitude may be justified.
