1.Ophthalmologic manifestation of Behcet's disease.
Yonsei Medical Journal 1997;38(6):390-394
Loss of vision in Behcet's disease is one of the most common, as well as one of the most serious, of its varied manifestations. Total blindness may often be the eventual outcome. The underlying problem in the eye, as well as in other organ systems, is an occlusive vasculitis. Although the most common ocular symptom is that of iridocyclitis, the presence of retinovascular lesions, especially necrotizing retinitis, is well known but often obscured by the severity of the anterior reaction, which precludes a good view of the retina. While Behcet's disease is characterized by spontaneous remissions and relapses, no external factors have been found to explain the length of remissions. Blindness, which occurs in up to 25% of patients, is one of the major causes of permanent disability.

PURPOSE: To evaluate and compare the efficacy and safety of cyclosporine 0.05% (Cyporin N eye drops 0.05%) to an active comparator (Restasis®) in moderate to severe dry eye patients. METHODS: This is a multicenter, randomized, double-blind, parallel, active control, non-inferiority, phase III study. Patients had a 2-week run-in period (during the run-in period, patients used artificial tears, if applicable), and afterward 158 patients were randomly assigned treatment for 12 weeks with cyclosporine 0.05% (with artificial tears, if applicable), in which the efficacy and safety were evaluated every four weeks. RESULTS: Corneal staining tests showed that in the per protocol set group, the study group was not inferior to the control group; the results for the full analysis set analytic group were the same. The number of adverse events reported from the 158 patients was not significantly different between groups (p = 0.1107). Additionally, other evaluations, including tolerability evaluations, clinical pathology examinations, and vital signs, show that there is no difference in terms of safety between the groups. CONCLUSIONS: Cyclosporine A 0.05% (Cyporin N eye drops 0.05%) is considered to have the same efficacy and safety compared to the active comparator.

Objective: This study correlated the patterns of ocular B- and A-scans of intraocular retinoblastoma (RB) with corresponding histopathology sections. It aimed to establish a more objective basis for determining intraocular retinoblastoma by ultrasonography (UTZ) and to determine the degree of malignancy and viability of the tumor cells.
Methods: New cases of retinoblastoma seen at the University of the Philippines-Philippine General Hospital (UP-PGH) from January 1994 to December 2003 were reviewed. Included were patients who underwent enucleation and whose eyeballs were processed at the UP Institute of Ophthalmology. Those with good quality ocular ultrasonographs (UTZ) and clear matching histopathologic sections were finally selected. Findings were correlated and analyzed.Results: Retinoblastoma (RB) showed multiplicity of lesions on UTZ corresponding to multiple lesions on histopathology. The following characteristic patterns were seen:
Very malignant RB or pseudorosettes: fine, grainy densities on B-scan with short to medium broad spikes on A-scan ("V-W" pattern).
Moderate differentiation with moderate necrosis and early calcific plaques: fine, dense grainy opacities on B-scan with multiple thin, high spikes admixed with tall, broad spikes of calcium deposits on A-scan.
Well-differentiated RB with compact viable cells and no necrosis: large, white densities on B-scan with an initial high spike and high internal reflectivity, sometimes "plateauing," on A-scan with no calcific deposits.
Complete tumor necrosis with calcific plaques: echolucent space with dense, white, plaque-like opacities on B-scan; flat or low spikes mixed with tall, broad spikes corresponding to calcium plaques on A-scan.
Normal vitreous, serous subretinal fluid, or recent hemorrhage: echolucent area on B-scan with flat or low spikes on A-scan.
Conclusion: The three most frequent findings in intraocular retinoblastoma were calcific plaques with liquefaction necrosis, multiplicity of lesions, and pseudorosettes. Ocular ultrasound of retinoblastoma showed good histopathologic correlation.

There are irreversible eyeball structural changes in high myopic patients. These changes include axial length, corneal radius, anterior chamber depth, fundus degeneration, macula thickness, etc. There is a close relationship between the damage degree of visual function and these changes. The incidence of complications, such as vitreous opacity, posterior vitreous detachment, cataract, glaucoma, posterior staphyloma and retina detachment, is also highly related to the myopia diopter. More and more researches have indicated that the myopia diopter and the level of visual function are affected by multiple factors. It is promising to detect all of these changes by different kinds of methods, and to assess visual function through these changes. By clarifying these changes, it is also useful to distinguish traumatic damage from disease to provide evidence for forensic assessment of eye injuries.

OBJECTIVETo study the pathological features of uveal melanoma and to evaluate their influence on patients' prognosis.
METHODSParaffin embedded uveal melanoma tissues of 115 cases were examined using routine pathologic methods. Three histological types were classified according to the modified Callender system and patients were followed clinically. The data were done regression and survival analysis by SPSS statistic soft.
RESULTSThe patient with epithelial cell type, mixed type, and spindle cell type uveal melanoma have different life times, the average life time is 35.6 +/- 21.5 months, 63.7 +/- 37.0 months, 69.5 +/- 36.5 months in turn, patients with epithelial uveal melanoma had shorter survival time than other two types. The survival time was negatively related to the largest diameter of contact area with the sclera, the largest height and the depth of tumor invasion to the sclera.
CONCLUSIONSEpithelial uveal melanoma is more malignant than the other two types. Histological classification of this tumor combined with other pathologic features can indicate the patient's prognosis.

7.Adenoma of nonpigmented epithelium in ciliary body: literature review and case report.
Journal of Zhejiang University. Science. B 2007;8(9):612-615
Adenomas of the nonpigmented ciliary epithelium (NPCE) are often clinically indistinguishable from amelanotic malignant melanomas of the ciliary body or metastatic carcinomas. This paper reports a case study of a distinctive variant of adenoma of the NPCE, which clinically appears as epiretinal membrane in the macular region. Histopathologic studies have revealed this is an adenoma of the NPCE. Identification of this clinic feature is important because it will miss the diagnosis of the adenoma of the NPCE. In this case study, B-scan ultrasonography as well as computerized tomography (CT) has been used to provide help in diagnosing the ciliary body tumor. Because of their anterior location in the ciliary body, partial lamellar sclerouvectomy is an effective method of treatment.

Pseudoexfoliation syndrome is characterized by the presence of gray-white flakes on the pupillary borders and anterior lens capsule, increased trabecular meshwork pigmentation, and association with glaucoma. We describe 3 patients with this syndrome seen at Asan Meidcal Center Department of Ophthalmology in 1989, and we focus on their clinical features and management. We believe that patients with this syndrome are not as rare in Korea as has been thought, judging by scant report of cases in the past.

10.Sixty cases with eyes injuries degree in forensic medicine.
Journal of Forensic Medicine 2009;25(5):368-369
OBJECTIVE:
To discuss the characteristics and main problems of eye injuries in forensic identification.
METHODS:
Sixty cases of eye injury in forensic expertise were retrospectively analyzed according to sex, age, employment, trauma-causing instrument and injury type, respectively.
RESULTS:
Of the 60 cases there are 61.7% being peasants and workers, 85.0% suffering from blunt trauma and 63.3% suffering from simple contusion.
CONCLUSION
Eyes injuries was mostly caused by blunt trauma. Pathological change of fundus was an important factor affecting the vision function. The injury-causing instruments, injury sites and medical history of eyes should be considered while evaluating the vision.
