Objectives : This study is aimed to investigate acupuncture treatments for blurred vision, tinnitus, difficulty in urination and bi-syndrome caused by aging process through oriental medical documents. methods : We researched 21 oriental medical classics for the acupuncture treatments of blurred vision, tinnitus, difficulty in urination and bi-syndrome caused by aging or deficiency. Results & conclusions : 1. Disharmony between yin and yang, disharmony between organs, disharmony of essence, qi, spirit, blood and body fluid are the main features of aging. 2. ST36, BL18, BL10, CV24, ST1, BL23 have been most frequently used for acupuncture to treat blurred vision caused by aging. For moxibustion, ST36 has been most frequently used. 3. GB2, TE21, TE17, SI19, TE3 are the mainly used points for acupuncture to treat tinnitus and deafness caused by aging. For moxibustion, LI1 and BL15 have been most frequently used. 4. CV3, CV7, CV4, BL67, LR8, LR4 have been most frequently used to treat difficulty in urination caused by aging. 5. LI11, GB34, GB30, LI4, ST36, TE10, TE5, Sama (extra point) have been most frequently used to treat numbness, paralysis and bi syndrome caused by aging.

Ocular toxoplasmosis is a disease caused by the infection with Toxoplasma gondii through congenital or acquired routes. Once the parasite reaches the retina, it proliferates within host cells followed by rupture of the host cells and invasion into neighboring cells to make primary lesions. Sometimes the restricted parasite by the host immunity in the first scar is activated to infect another lesion nearby the scar. Blurred vision is the main complaint of ocular toxoplasmic patients and can be diagnosed by detection of antibodies or parasite DNA. Ocular toxoplasmosis needs therapy with several combinations of drugs to eliminate the parasite and accompanying inflammation; if not treated it sometimes leads to loss of vision. We describe here clinical features and currently available chemotherapy of ocular toxoplasmosis.

컴퓨터 비전에서 흐릿한 영상은 영상 인식률을 저하시키는 중요한 요인이다. 이것은 주로 카메라가 불안정하게 초점을 맞추지 못하거나, 노출시간동안 장면의 물체가 빠르게 움직일 때 발생한다. 흐릿한 영상은 시각적 품질을 크게 저하시켜 가시성을 약화시키며, 이러한 현상은 디지털카메라의 기술이 지속적으로 발전하고 있음에도 불구하고 빈번하게 일어난다. 본 논문에서는 합성곱 신경망으로 설계된 심층 멀티 패치 계층 네트워크(Deep multi patch hierarchical network)를 기반으로 수정된 빌딩 모듈을 대체하여 입력 영상의 디테일을 잡고 주의 집중 기법을 도입하여 흐릿한 영상 속 물체에 대한 초점을 다방면으로 맞추어 영상을 강화한다. 이것은 서로 다른 스케일에서 각각의 가중치를 측정 및 부여하여 흐림의 변화를 차별적으로 처리하고 영상의 거친 수준에서 미세한 수준까지 순차적으로 복원하여 글로벌한 영역과 로컬 영역 모두 조정한다. 이러한 과정을 통해 저하된 화질을 복구하고 효율적인 객체 인식 및 특징을 추출하며 색 항상성을 보완하는 우수한 결과를 보여준다.

The process of detecting edge in an image is an important component of many Pattern Recognition and Computer Vision applications. In many practical cases, there exist blurred images due to defocussing, movement of an object and so on. In addition, local perturbation noise can be added to the images. We propose the edge detection technique in blurred and noisy image. For this, we use Fuzzy pyramid linking mothod to remove noise and enhance the edge in images. We develop contrast intensifier using the concept of Fuzzy sets as a postprocessing.

Purpose: The purpose is to study the effects of the vision training, as a non-surgically treated vision therapy, on the objective and the subjective symptoms of the patients with intermittent exotropia combined with vertical deviation. Method: For the boys at the age of eight with intermittent exotropia, who report a long-distance blurred vision, dazzling, and intermittent diplopia more than ten times a day, the vision training had been practiced for seven weeks. The objective and subjective symptoms have been examined after six months from the end of the training. Results: The objective and the subjective symptoms have been improved after the seven weeks training and the improvements lasted after six months from the end of the treatment. Conclusion: Non-surgical treatment for the patients with intermittent exotropia, including intermittent exotropia combined with vertical deviation like this case, should be considered as an auxiliary treatment and on the preferential basis.

Certain parts of shellfish contain poisonous substances and cause intoxication. Tetramine toxin is found in the salivary gland of Neptunea. Three family members were admitted to the hospital with chief complaints of dizziness and blurred vision, gait disturbance, and spasms of the lower extremities after ingesting Neptunea. Physical examination revealed sluggish pupil light reflexes, but laboratory studies were normal. Symptoms were completely resolved within 24 hours after injection of atropine. We report a case of three patients with dizziness and blurred vision, gait disturbance, and spasms of the lower extremities due to Neptunea tetramine toxin.

Background: Opioid analgesics are widely used to reduce postoperative pain and to enhance post-operative recovery. However, orthostatic intolerance (OI) induced by opioid containing intravenous patient controlled analgesia (IPCA) may hinder postoperative recovery. This study investigated factors that affect OI in patients receiving IPCA for postoperative pain control. Methods: OI was instantly evaluated at the time of first ambulation in 175 patients taking opioid containing IPCA after open and laparoscopic subtotal gastrectomies. Patients were classified as having OI if they experienced dizziness, nausea/vomiting, blurred vision, headache, somnolence and syncope. Factors contributing to OI were assessed with logistic regression analysis. Results: Out of 175 patients, 61 (52.6%) male and 44 (74.6%) female patients experienced OI at the time of first ambulation. The frequency of OI related symptoms were dizziness (97, 55.4%), nausea (46, 26.3%), headache (9, 5.1%), blurred vision (3, 1.7%) and vomiting (2, 1.1%). Significant risk factors for OI were gender (P=0.002) and total amount of opioids administered (P=0.033). Conclusions: The incidence of OI is significantly higher in male than in female patients and is influenced by the opioid dose.

Ophthalmic complications after tooth extraction are rare but discomforting events. This paper reports the rare complications of a 20-year-old male patient who presented with transient blurring of vision after surgical extraction of several teeth under general anesthesia. Additional diagnostic tests were performed to discern the reason for the pseudomyopia. A literature review was carried out by searching for articles published from 1936 to 2019 using the keywords "dental," "ophthalmic," "complication," "blurring of vision," and "accommodation disturbance" in PubMed. Only six patients with detailed ophthalmic symptoms similar to those of our patient have been reported. If blurred vision or a myopic shift in refraction is present, pseudomyopia should be suspected, and cycloplegic refraction is essential for diagnosis. The condition improves spontaneously

Though the increment of using computer vision system in modern industry, there are lots of difficulties to measure precisely because of measurement error distortion phenomenon. Among these reasons, the distortion of edge is dominant reason which is occurred by the blurred image. The blurred image is happened when camera can not discriminate its precise focus. To calibrate and generalize distortion phenomenon is important. Thus, we must fix the discrimination criteria which is collected by image recognition of precise focus. Also, radial distortion causes an inward or outward displacement of a given image point from its ideal location. This type of distortion is mainly caused by flawed radial curvature curve of the elements. Thus, we were analyzed the distortion in terms of the changed with lens magnification.

In computer vision system of modern industry precise measuring has lots of dfficulties because of measurement error due to distortion phenomenon. Among the difficulties, the distortion of edge is regraded as a dominent problem. which is caused by the vlurred image. The blurred image apperar when camera can not discriminate its precise focus. So. it is very important to decide focus of lens and to develop algorithm in order to correct distortion phenomenon. Thus. discrimination criteria obtained by image information of precise focus must be fixed in advance. The gray level histogram of image acquired from blurred edge tends to show a uniform distribution. Bimodal intensity histogram is related with condition of focus, and it is possible to find good condition of focus by using bimodal histogram of entropy.
