Methotrexate (MTX) is a folate analog with anti-proliferative, anti-inflammatory and immunomodulatory effects.It is widely used in clinical practice to treat various diseases, including malignant tumors and autoimmune diseases.MTX is used for treating eye diseases by local injection or whole-body administration. Its safety and efficacy have been confirmed. The intravitreal injection can reduce the whole-body use of glucocorticoids and immunosuppressive agents, so it is applied in ophthalmology increasingly. The specificity of MTX has been found in its application in special patients, such as men and women in pregnancy preparation period, pregnant women, lactating women, children, adolescents and the elderly. The dosage varies from patient to patient. Common adverse reactions to low-dose MTX include gastrointestinal symptoms, liver dysfunction, etc. Serious adverse reactions are relatively rare, but pharmaceutical monitoring is still necessarily needed. This review summaries the usage and adverse reactions of MTX in clinical practice, to provide reference for its application in clinical practice in ophthalmology.

目前Wetlab眼科手术教学采用猪眼球作为教学模型，与实际手术差别较大，且无法满足外眼手术教学的需求。通过使用带有眼球、眼外肌、眶组织、眶骨及眼睑结构的全眼模型，可高度模拟真实手术场景，覆盖更多眼科手术教学需求。基于全眼模型构建多个眼科手术教学平台，依照培养阶段设计手术课程，创建新的评价体系，改变传统将“内眼”“外眼”分开的教学理念，可使年轻医师从一开始就建立眼科“分科而不分割”的整体思维，从而使眼科手术培训更加规范和完善。
Porcine eyes have been used as animal model in ophthalmic surgery training. However, it differs greatly from real surgery and cannot meet the needs of external eye surgery teaching. Porcine orbit model with eyeball, extraocular muscles, orbital tissue, bones and eyelids can be more realistic simulation of real surgeries and cover more needs for ophthalmic surgery teaching. By setting up ophthalmic surgery teaching platforms, designing staged course and creating new assessment methods based on porcine orbit model, the traditional concept about separation of internal and external eye is changed. This helps young doctors to establish a holistic view from the very beginning,that ophthalmic surgeries should not be split because of subspeciality. In this way, ophthalmic surgery training will become more standardized and perfected.
近些年来，眼科疾病的临床诊断治疗及其病理发展的研究对医学影像学技术的要求日益增高，磁共振技术已广泛应用于研究眼科疾病的发病机制、治疗和分析预后。基于体素的形态学分析(voxel-based morphometry，VBM)作为一种新型的磁共振图像的分析方式，VBM可以对活体脑进行无创的形态学研究，定量分析磁共振图像中每一个单独体素内的白质、灰质的密度和体积的变化，从而反映对应区域的解剖学结构差异，能发现常规MRI不能检测到的灰质和白质结构的细微改变。不同于那些只作用于预设的感兴趣区域的分析方法，VBM完全没有偏向性，它探测全脑的异常变化，无需对感兴趣区的先验性假设，不会被研究人员的主观思维影响。这提供了一种全新的方法来探索眼科疾病中的神经病理变化，尤其在青光眼和弱视的研究中应用最多。
With the increasing requirements for medical imaging technologies in clinical diagnosis, treatment and pathological basis research of ophthalmic diseases, magnetic resonance imaging (MRI) has been broadly used in the diagnosis and prognostic evaluation of ophthalmic diseases. As a novel analytic method of MR images, voxel-based morphometry (VBM) quantitatively analyzes the changes in brain gray, white matter density and volume in each individual voxel in MR images to reflect the differences of anatomical structures in the corresponding areas, and it provides a novel way to reveal the neuronal pathological changes in ophthalmic diseases.
