The open Hospital Attending Physician System has been discussed and operated for developing the efficiency and the substitutes for an increase in medical expenses, for overlapping investment in medical resources, and for normalization of medical delivery system. This study assessed the related factors to the acceptance and introduction of Attending Physicians on ophthalmologist. Data was collected mail response to 179 ophthalmologists in 2005. Applying multilevel logistic regression, we examined the relationship between their acknowledgment, attitude and acceptance of the open Hospital Attending Physicians System. The percentage of participation in Hospital Attending was indicated to be 3.9%. The 44.7% of all participants agreed to adopting the Hospital Attending, 33.5% of doctors are willing to participate in the future. The positive and normal attitude of physician toward the Hospital Attending is 6.6 times (95%CI 1.315, 33.138) and 55.2 times(95%CI 11.352, 268.347) more than that of negative after adjustment for other variables. Attitude was found to be the important factor influencing physicians' participation in the Attending Hospital. Thus, it is need to development and implication for the strategies that lead the practical necessity and positive attitude toward the Attending Hospital.

Retinopathy of prematurity (ROP) is a major cause of blindness that affects premature infants. With advances in neonatology, ROP is likely to emerge as the most serious problem of vision loss in children even in developed countries; such a situation could be called the third epidemic of ROP. However, controversy and uncertainty still surround favorable outcomes of ROP. For successfully controlling ROP, timely and accurate screening is crucial because early treatment leads to favorable outcomes. Standard guidelines, including ROP classification, have provided satisfactory instructions for the screening and treatment of ROP. To improve the structural and functional outcomes of ROP, optimizing the timing of surgical interventions including cryotherapy, laser-photocoagulation, encircling, and vitrectomy is essential; these interventions can prevent the sequelae of ROP. It is essential for the neonatologist and the ophthalmologist to cooperate extensively for the successful treatment of ROP.

안저 출혈은 망막 조직과 혈관의 이상을 의미한다. 따라서 안과 의사는 안저의 출혈성 변화가 발생하면 이에 따른 치료 계획을 수립하기 위해 치료 전과 치료 중간, 치료 이후 등 병변의 진행상황을 파악하기 위해 여러 가지 안과 검사의 출혈 성 정도의 평가를 위해 오더를 지시한다. 현재 가장 유용하고 보편적인 안저검사에는 빛간섭단층촬영(OCT), 안저촬영(FP), 형광안저혈관조영술(FAG) 등이 있다. 중증 안저 출혈에 대한 치료 계획을 수립하기 위한 기존의 형광안저혈관조영술 검사에는 한계가 있다. 저자들은 광각형광혈관조영술을 이용하여 동공주위촬영과 5-quadrant 방법을 수행할 것을 제안한다. 이 방법을 사용하면 신속히 검사 부위를 결정하고 최대한 출혈의 반경을 피해 안과 의사에게 손상된 조직과 이상 혈관의 범위를 제공할 수 있다. 그런데도 불구하고 안과 의사가 안저 출혈이 매우 심각하여 광각형광혈관조영술이 무의미하다고 판단하는 경우가 있다. 이런 경우 대체검사로 안과초음파 및 망막전위도의 오더가 발생한다. 따라서 우리는 안 초음파 및 망막전위도 검사 필요성에 대해 당위성을 인정해야 하고, 정확하게 수행해야 한다.

The paper presents a technique to identify the boundary of the optic disc in infant retinal digital images using an approach based on active contours (snakes). The technique can be used to be develop a automate system in order to help the ophthalmologist's diagnosis the retinopathy of prematurity (ROP) disease which may occurred on preterm infant,. The optic disc detection is one of the fundamental step which could help to create an automate diagnose system for the doctors we use a new kind of active contour (snake) method has been developed by Chenyang et. al. [1], based on a new type of external force field, called gradient vector flow, or GVF. GVF is computed as a diffusion of the gradient vectors of a gray-level or binary edge map derived from the image. The testing results on a set of infant retinal ROP images verify the effectiveness of the proposed methods. We show that GVF has a large capture range and it's able to move snakes into boundary concavities of optic disc and finally the optic disk boundary was determined.

Accurate and reliable Information improves decision making, reduces costs, and saves time. The ophthalmic Libraries supply quality ophthalmic information to the ophthalmologists to serve the patients in a better way and stimulate the growth of ophthalmic field. This paper aims to study the usage of library collection, services and assistance among the Ophthalmologists - Eye Doctors in India. A survey method is used to obtain the ophthalmologists' usage of library collection, services and assistance. Through convenient sampling method, a structured questionnaire is circulated to the ophthalmologists in India and 633 ophthalmologists are responded. Among the 633 ophthalmologist, 82.15% of the ophthalmologists use the library collection - book. 73.46% of the ophthalmologists use the online data / journals. 89.73% of the ophthalmologists seek assistance to locate books/articles/documents. There exists a significant difference between the ophthalmologists use of Library Service and gender (p value 0.001**). There exists a significant difference between the ophthalmologists use of Library Assistance / help and designation category (p value 0.000**). There exists a significant difference between the ophthalmologists use of Library Assistance / help and working experience (p value 0.017**). There exists a significant difference between Library Services (p value 0.009**), Library Assistance / help (p value 0.000**) and institution type.

Trochlear nerve palsy associated with spontaneous subarachnoid hemorrhage (SAH) is known to be a rare malady. We report here on a patient who suffered with left trochlear nerve palsy following rupture of a right posterior communicating artery aneurysm. A 56-year-woman visited our emergency department with stuporous mental change. Her Hunt-and-Hess grade was 3 and the Fisher grade was 4. Cerebral angiography revealed a ruptured aneurysm of the right posterior communicating artery. The aneurysm was clipped via a right pterional approach on the day of admission. The patient complained of diplopia when she gazed to the left side, and the ophthalmologist found limited left inferolateral side gazing due to left superior oblique muscle palsy on day 3. Elevated intracranial pressure, intraventricular hemorrhage or a dense clot in the basal cisterns might have caused this trochlear nerve palsy.

Aneurysmal bone cyst (ABC) is benign vascular lesion destructing the cortical bone by the expansion of the vascular channel in the diploic space that usually involve long bone and spine. Orbital ABC is rare and the clinical symptoms deteriorate rapidly after initial slow-progression period for a few months. A 12-year-old female patient visited ophthalmologist due to proptosis and upward gaze limitation of the right eye, and orbital mass was noted in the upper part of right eye on orbital MRI. Five months later, exophthalmos was worsened rapidly with other features of ophthalmoplegia. Orbital mass was enlarged on MRI with intracranial extension. Surgery was done through frontal craniotomy and intracranial portion of the tumor was removed. Destructed orbital roof and mass in the orbit was also removed, and surrounding bone which was suspected to have lesion was resected as much as possible. Histopathological diagnosis was aneurysmal bone cyst. Postoperative course was satisfactory and the patient's eye symptoms improved. Authors report a rare case of orbital ABC with review of the literature. Exact diagnosis by imaging studies is important and it is recommended to perform surgical resection before rapid-progressing period and to resect the mass completely to prevent recurrence.

Spinal intradural cysticercosis is a rare manifestation of neurocysticercosis. We report a unique patient who showed visual symptoms and normal imaging of the brain caused by isolated spinal neurocysticercosis. A 59-year-old male patient was admitted to the emergency unit with a history of severe headache and progressive blurred vision. Brain computed tomographic scanning and magnetic resonance imaging showed normal cerebral anatomy without hydrocephalus. The fundoscopic evaluation by an ophthalmologist showed bilateral papilledema. Perimetry studies revealed visual field defects in both eyes. With the diagnosis of pseudotumor cerebri, a lumbar tap was attempted; however, we could not drain the cerebrospinal fluid in spite of appropriate attempts. Lumbar magnetic resonance imaging revealed multilevel intraspinal lesions that were confirmed histologically to be neurocysticercosis. An intraoperative lumbar puncture revealed an increased opening pressure and cytochemical analysis showed elevated cerebrospinal fluid protein level. The headache resolved immediately after surgery. However, the visual symptoms remained and recovered only marginally despite antihelminthic medications after six months of operation.

Treatment of paraclinoid aneurysms weather by surgery, or endovascular embolization has a risk of visual loss due to optic neuropathy, or diplopia due to cranial nerve palsies. Visual complications occur immediately after the clipping, whereas they can occur variable time after endovascular coiling. Recently, endovascular coiling for paraclinoid aneurysm is regarded as a safe and feasible treatment. But it still has risks of acute thromboembolic complication, or cranial nerve palsies. A 45-year-old woman was referred from local hospital to our hospital due to ruptured large ICA dorsal wall aneurysm. A total of 12 coils (195 cm) were used for obliteration of aneurysm. Postoperative diffusion weighted image showed no abnormal signal intensity lesion and magnetic resonance angiography demonstrated no sign of vasospasm, or vessel narrowing. But, she complained visual problem 23 days after coil embolization. Ophthalmologist confirmed the left optic disc atrophy on fundoscopy. Although steroid was started, but monocular blindness did not recover completely. The endovascular embolization of paraclinoid aneurysm, especially projecting superiorly with large irregular shape, has the risk of progressive visual loss because of the proximity to optic nerve.
