Sclerosing pseudotumor of the orbit is a unique clinico-pathological entity which is characterized by an insidious, chronic and progressive fibrosing process damaging orbital structures.As this entity forms immunologically mediated fibrosis even in early phase and frequently involves orbital apex and adjacent intracranial structures, it can cause severe ocular symptoms, visual impairments and even can threaten the life. We report clinical characteristics of nine biopsy-proven cases of sclerosing pseudotumor of the orbit.Five cases out of them have shown clinical improvement with combined therapeutic approach of surgical debulking, systemic steroids therapy, radiation therapy, and immunosuppressive therapy. We believe that prompt diagnosis through biopsy, early introduction of radiation therapy and immunosuppressive therapy are the most rational, currently available treatment for sclerosing pseudotumor of the orbit.

OBJECTIVES: To study the virtual reality-pattern visual evoked potential (VR-PVEP) P100 waveform characteristics of monocular visual impairment with different impaired degrees under simultaneous binocular perception and monocular stimulations. METHODS: A total of 55 young volunteers with normal vision (using decimal recording method, far vision ≥0.8 and near vision ≥0.5) were selected to simulate three groups of monocular refractive visual impairment by interpolation method. The sum of near and far vision ≤0.2 was Group A, the severe visual impairment group; the sum of near and far vision <0.8 was Group B, the moderate visual impairment group; and the sum of near and far vision ≥0.8 was Group C, the mild visual impairment group. The volunteers' binocular normal visions were set as the control group. The VR-PVEP P100 peak times measured by simultaneous binocular perception and monocular stimulation were compared at four spatial frequencies 16×16, 24×24, 32×32 and 64×64. RESULTS: In Group A, the differences between P100 peak times of simulant visual impairment eyes and simultaneous binocular perception at 24×24, 32×32 and 64×64 spatial frequencies were statistically significant (P<0.05); and the P100 peak time of normal vision eyes at 64×64 spatial frequency was significantly different from the simulant visual impairment eyes (P<0.05). In Group B, the differences between P100 peak times of simulant visual impairment eyes and simultaneous binocular perception at 16×16, 24×24 and 64×64 spatial frequencies were statistically significant (P<0.05); and the P100 peak time of normal vision eyes at 64×64 spatial frequency was significantly different from the simulant visual impairment eyes (P<0.05). In Group C, there was no significant difference between P100 peak times of simulant visual impairment eyes and simultaneous binocular perception at all spatial frequencies (P>0.05). There was no significant difference in the P100 peak times measured at all spatial frequencies between simulant visual impairment eyes and simultaneous binocular perception in the control group (P>0.05). CONCLUSIONS VR-PVEP can be used for visual acuity evaluation of patients with severe and moderate monocular visual impairment, which can reflect the visual impairment degree caused by ametropia. VR-PVEP has application value in the objective evaluation of visual function and forensic clinical identification.

In 2004, the University of the Philippines Manila published the Philippine Guidelines on Periodic Health Examination (PHEX): Effective Screening for Diseases among Apparently Healthy Filipinos. 1 The document was envisioned to “contribute… to the quality and efficiency of health care and health maintenance for all Filipinos… It was an appeal for rational medical decision-making, and an important step toward “equitable distribution of health and health resources.” The guidelines were prepared by designated task forces, with vision disorders, specifically vision impairment, and glaucoma identified as areas of interest. PHEX recommendations were drafted using standardized principles and a common protocol, with each statement undergoing four phases of development: (1) preparation of the evidence- based draft; (2) en banc meeting that gave panelists a chance to assess and revise the draft, where issues of feasibility, resource limitations, value judgment, and experts’ opinions were taken into account. A consensus was declared when at least 75% agreed on a recommendation; (3) for unresolved issues, modified Delphi technique was employed by correspondence until a consensus was reached or a maximum of three circulations were accomplished. If still unresolved, the issue was labeled as such and included in the final draft; (4) lastly, a public forum was conducted before the final draft was written. In this manner, the recommendations for Screening for Visual Impairment were written by the Task Force for Vision Disorders.

PURPOSE: To investigate the efficacy of a computerized visual acuity test, the SNU visual acuity test for children. METHODS: Fifty-six children, ranging from 1 to 5 years of age, were included. In a dark room, children gazed at and followed a circular dot with 50% contrast moving at a fixed velocity of 10 pixels/sec on a computer monitor. Eye movement was captured using a charge coupled device camera and was expressed as coordinates on a graph. Movements of the eye and dot were superimposed on a graph and analyzed. Minimum visualized dot diameters were compared to the Teller visual acuity. RESULTS: Ten eyes (8.9%) of six children failed to perform the Teller visual acuity test, and two eyes (1.8%) of one patient failed to perform the SNU visual acuity test. The observed Teller visual acuity and SNU visual acuity were significantly correlated (p < 0.001). Visual angle degrees converted from the Teller visual acuity and SNU visual acuity were also significantly correlated (p < 0.001). CONCLUSION: The SNU visual acuity using moving targets correlated well with Teller visual acuity and was more applicable than the Teller acuity test. Therefore, the SNU visual acuity test has potential clinical applications for children.

This guideline is developed to provide criteria for evaluating permanent impairment of the visual system as it affects an individual's ability to perform activities of daily living. This new assessment system is based on the 5th and 6th edition of American Medical Association and McBride impairment assessment system but revised on the consideration of Korean culture and simple application. This evaluation of impairment is based on an assessment of visual acuity and visual field. Especially it weighs binocular vision and binocular visual fields and the binocular vision and binocular visual fields provide 50% of weight and the right and left eye each contribute 25%. A further adjustment of the impairment rating is included at the final step of this evaluation. Functional deficits for individual adjustments include diplopia, problem of accommodation, abnormality of eyelids, tearing, cosmetic problems from cornea opacity, glare, aphakia, and dark-adaptation. The adjustment can be added to impairment rating up to 15%. Further study is necessary to revise and update of this disability evaluation that have potential problems in actual application.

OBJECTIVE: Memory Impairment has been proposed as the first sign in preclinical and early Alzheimer's disease (AD). This study aims to assess the utility of a new memory test based on Free and Cued Selective Reminding Test using pattern cue that seems useful for detecting memory impairments associated with AD. METHODS: Twenty-six patients with mild cognitive impairment, 24 AD patients at a mild stage, 35 normal controls and 8 Lewybody dementia (LBD) patients at a mild stage took part in the study. A newly devised Pattern Cued Recall Test (PCRT) was compared with established memory test, the word list recall from the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD-K). To assess the ability of the PCRT subtests and CERAD-K to screen dementia, receiver operating characteristic curves were plotted. RESULTS: The distinctive feature of the PCRT was that encoding specificity was increased by adding an immediate cued recall stage at the encoding phase. PCRT was confirmed as having sufficient validity to diagnose dementias. Compared to CERAD-K, the PCRT had similar accuracy of discriminating AD. But the analysis showed better diagnostic validity of PCRT than CERAD-K in LBD. Therefore, this test appears to be, especially, well suited for the diagnosis of mild LBD. CONCLUSION: This study showed that a memory test based on controlled encoding and retrieval condition and especially using pattern cue could be effective methodology for mild AD and LBD from normal control. PCRT could be an alternative to diagnose LBD by testing visual impairments, which is a hallmark symptom of LBD. Therefore, a further clinical study should be promising.

A 2-year-old intact female Bengal cat was presented with a 6-month history of visual impairment. The cat manifested bilateral negative menace responses and dazzle reflexes and sluggish pupillary light reflexes. Bilateral fundus changes included generalized tapetal hyperreflectivity, advanced retinal vascular attenuation, and increased pallor of the optic disc. A diagnosis of bilateral retinal degeneration was made. The clinical findings suggest that the investigated Bengal cat was most likely to have an inherited retinal degeneration. Further studies of the Bengal cat breed are needed to determine the prevalence of inherited retinal degeneration in this breed in Korea.

BACKGROUND: It has been known that the prevalence of depression is increasing and depressive mood is accompanied with various physical symptoms in the elderly. In this research, we studied various physical symptoms of the elderly patients and how many of those symptoms were associated to depressive mood. We also investigated how much their doctors were concerned about depressive symptoms of the patients. METHODS: The subjects were 135 patients over 60 years old, who visited geriatric center and department of family medicine in a university hospital from December 2002 to May 2003. Individual interviews were conducted among the subjects and all symptoms who suffered from within a month from the time of inter view, depression score, stress score, functional status and their sociodemographic factors were assessed. Finally, doctor's diagnosis or comments on depressive mood were assessed based on the medical documents of the elderly patients with depression. RESULTS: 56% of the subjects had depressive mood. Common symptoms of subjects were memory impairment, visual disturbance, fatigue, arthralgia, and thirsty sense. The more depressive mood the elderly have, the more physical symptoms they have. The physician paid their attention to depressive mood in 13% of the cases among the elderly with depressive mood. Depressive mood was affected by whom they lived together with, regular exercise and stress. CONCLUSION: This study shows that most of the elderly patients had depressive mood and their common symptoms were associated to depressive mood. The stress and living together with their children were risk factors for depression of the elderly. However, depressive mood was less found among those patients who had spouse and who exercised regularly. Though physicians more likely recognize the depressive mood of the elderly as depression was severer, still little attention was paid to depressive mood in the elderly.

In the present study, we have evaluated the mutations of the TIGR[Trabecular meshwork Inducible Glucocorticoid Response] gene, which has been reported to be associated with the glaucoma, in primary open angle glaucoma[POAG], normal tension glaucoma[NTG], and steroid-induced glaucoma[SIG]. We have analyzed the TIGR gene in 18 members of 3 families affected with POAG, 28 familially unrelated patients with POAG, 32 patients with NTG, 30 patients with SIG, and 45 normal subjects.DNA was extracted from the blood samples of each patient, exon 2 and exon 3 of the TIGR gene were amplified by PCR and DNA sequencing was performed.No mutation was found in familially unrelated patients with POAG.Two kinds of mutation[Ser341Pro, Gly367Arg]were found in 3 families affected with POAG.Another mutations, located in exon 3, were detected in one NTG patient and in one SIG patient, but they were silent substitution.Identification of TIGR gene mutation will provide early diagnosis of POAG before irreversible visual impairment develops in cases of positive family history of glaucoma.
