A Study for Viral Identification of Acute Viral Conjunctivitis

Acute viral conjunctivitis was known as an infectious disease affected by various viruses and characterized seasonal variation, prevalent especially in summer. In Korea, the clinic loepidemiologic study of AVC was not conclusive. Therefore, further research should be conducted to improve the primary health care and the application of diffrential diagnosis and its therapy. Clinical symptoms and signs of 131 patients who was confirmed viral conjunctivitis among 237 patients was evaluated at the Chung-Ang University Hospital in 1987, 1989 and 1990. Along with physical examination, specimens from the conjunctival swab were cultured and isolated, and a sereologic test-Neutralizing test for enterovirus 70, and complement fixation test for adenovirus-was performed. As a result, acute hemorrhagic conjunctivitis was relatively epidemic in 1987 and 1990 (67.7 and 47.1 %), and epidemic keratoconjunctivitis in 1989 (91.8%).

The Investigeation of the Influneces of Ocular Symptoms on Environmetal Factors of VDT Workers

VDT syndrome is the disease entity that affects many workers on the various visual function as well as on some general health conditions including neurologic, circulatory and musculoskeletal system and it tends to increase day by day. We performed a series of investigation to evaluate the influences of VDT work on the subjective symptoms by means of questionnaire application with the control of non-VDT workers. It revealed that the susceptibility in occurrence of impairment of ocular functions like asthenopia as well as the disturbances of musculoskeletal circulatory, gastrointestinal, and nervous systems were more pronounced in the VDT workers' group than the control group, and the environmental factors like working hours, air pollution, and noise also contributed for the worsening of the ocular and systemic symptoms. It is suggested that the improvement of operating environment by the implementation of comprehensive epidemiological study in association with the improvemental task of working situations and working times in long term advocated would decrease the VDT syndrome among VDT workers.

The Investigation of the Changes of Ocular Function in VDT Workers

VDT syndrome has been understood as the outocme of the computerized socio-economic cultures in this modern age. It affects many workers on larious visual functions as well as affecting some general health conditions including neurologic, circulatory, and musculosckeletal system. We conducted series of investigations to evaluate the influence of VDT work on the physiologic functions using objective ocular examinations on VDT workers with non-VDT workers as controls. Prolongation of near point decreased accommodation amplitude, myopic shift of refractive condition, and decreased amout of tear formation were significantly indicative in the VDT workers' group. The above functional disturbances can significahtly, deteriorate not only working effeciency but general physical condition if appropriate measures are not provided quickly. Therefore, it is firmly suggested that a comprehensive epidemiological study should be implemented aimed at ImprovIng working situations for VDT workers.

Corneal Complication after 3M(R) Style 78E Anterior Chamber Intraocular Lenses Implantations

Anterior chamber intraocular lenges(IOLs) are important roles in visual rehabilitation in patients with vitreous loss during cataract surgery and secondary IOLs implantations. We examined three patients among 21 cases had implanted 3M(R) style 78E ACLs, which was closed loop, semiflexible and they experienced decreased vision due to bullous Keratopathy. ACLs were removed immediately, and then scanning electron microscopy(SEM) was performed. This study shows that fibrous tissues and inflammatory cells were precipitated around loop-optic junction. So, we expect this ACLs must be avoid especially secondary ACL implantations.
