Purpose: To measure normal retinal nerve fiber layer thickness (RNFLT) in the peripapillary region of Koreans using a scanning laser polarimeter, the nerve fiber analyzer (GDx VCC). Methods: Two hundred ninety-nine eyes of 299 healthy subjects (156 men, 143 women) were recruited for this study. No subject had diabetes mellitus, hypertension, or any other neurologic disorders. All subjects were normal at ophthalmologic examination, which was assessed by slit-lamp biomicroscopy using a 90-diopter lens, Goldmann applanation tonometry, and Humphrey visual field analysis. Using the GDx VCC, we analyzed the mean value of each parameter in GDx VCC (average at global, superior, inferior, superior maximum and inferior maximum) and evaluated the difference between men and women and each decade of age. Results: Mean RNFLT parameters in GDx VCC were global 56.42±6.84?m, superior 70.51±8.70?m, inferior 67.55±9.04?m, superior maximum 83.52±12.38?m, and inferior maximum 82.64±12.70?m. The parameters which showed a difference between men and women were superior average and superior and inferior maximum average RNFLT. The superior RNFLT was thicker than the inferior ones. RNFLT was not statistically different in each decade of age. Conclusions: We can make good use of the normal parameters of GDx VCC in Koreans for early diagnosis and follow-up of glaucoma.
Anterior Lens Capsule Abnormalities in Alport Syndrome

Alport syndrome is a hereditary, progressive disease characterized by progressive nephritis, sensorineural deafness, and ocular abnormalities, including anterior lenticonus. The ultrastructure of the lens capsule abnormalities in Alport syndrome is reported. Four anterior lens capsules from 31-year-old patient and 26-year-old patient with lenticonus who were affected by the Alport syndrome were obtained at capsulectomy. And all four anterior lens capsules were examined by transmission electron microscopy. The histopathologic findings showed that the thickness of the anterior lens capsules was decreased (4~13 μm) and that there were many vascular dehiscences localized at the inner part of the lens capsule. There were large numbers of capsular dehiscences containing fibrillar materials and vacuoles. The anterior capsules were clearly fragile in this disease, forming the basis for the progressive lenticonus and anterior polar cataract.

Pyogenic liver abscess is a serious clinical disease with severe complications in 10-20% of the cases. Metastatic septic endophthalmitis is a rare complication associated with liver abscess. Despite appropriate treatment, the outcome is devastating. We experienced a case of pyogenic liver abscess complicated with endophthalmitis. The bacterial organism cultured from liver abscess was Klebsiella pneumoniae. Treatment of this patient was composed of percutaneous drainage under ultrasonographic guidance, systemic and intravitreal antibiotic therapy. After treatment for 6 weeks, the liver abscess was resolved completely, but the visual outcome was very poor despite intensive treatment. We report a case of pyogenic liver abscess complicated with endophthalmitis. (Korean J Gastroenterol 2001;38:120-123)
