BACKGROUND AND OBJECTIVES

The global pandemic caused by Coronavirus Disease 2019 (COVID-19) has affected millions, with growing evidence of the potential role of ocular tissues in viral transmission. At the time of writing, local data regarding the phenomenon was limited. This study investigated external ocular manifestations in patients with COVID-19 at a referral center in the Philippines, examined correlations between demographics, systemic manifestations, and laboratory results with ocular manifestations, and determined their timing relative to systemic symptoms.

METHODS

This single-center, descriptive cross-sectional study was carried out from December 8 to 18, 2020 at the adult COVID-19 wards of the Philippine General Hospital involving 72 participants. Data collection involved relevant clinical history taking and performing gross eye examination. The prevalence of ocular manifestations was described with 95% confidence intervals. Correlations between ocular manifestations and quantitative variables were analyzed with point-biserial correlation, and associations with qualitative variables were tested using chi-square or Fisher’s exact tests.

RESULTS

Among participants, 31.9% presented with ocular manifestations with foreign body sensation as the most prevalent ocular symptom (11.1%) and conjunctival hyperemia as the most prevalent ocular finding (19.4%). The median age of patients with ocular manifestations was 41 years old with a higher prevalence in the male population (73.9%, CI=95%, p=0.001). No significant correlation was observed between presence of external ocular manifestations and the different systemic and ocular co-morbidities as well as with COVID-19 clinical classification. Among those who experienced symptoms, majority (29.2%) of the patients experienced systemic symptoms prior to the onset of ocular symptoms. Ocular complaints may present as the sole manifestation (13.9%). Several laboratory parameters were measured and only temperature and AST levels showed a low positive correlation with the presence of ocular manifestations. 

CONCLUSION

Ocular manifestations occur in roughly one third of patients with COVID-19 based on this study population. With some individuals presenting with ocular signs or symptoms as the initial and sole manifestation, healthcare practitioners must exercise caution and remain vigilant in managing patients who present as such. At the time of writing, this is the first local study investigating the different external ocular manifestations in patients with COVID-19. There is a need to pursue more robust studies and conduct more local investigations which will guide both ophthalmologists and other practitioners in strengthening existing guidelines regarding precautionary practices, clinical diagnosis, and management of COVID-19 patients.

The paper introduces Professor SUN Shentian's experience in clinical practice of Ningshen (tranquilizing the mind) point. This point is an empirical point discovered by Professor SUN on the basis of meridian differentiation, nerve function and anatomic location, and in association with the years of clinical practice. The point is located in the prefrontal area, jointed with the distribution of the governor vessel, and responded to the body surface projection area of the frontal pole. It works on regulating the mind, regaining consciousness, improving cognition, alleviating depression, mutually treating physical and mental disorders, as well as unblocking collaterals, regulating the tendons and relieving spasm. This point is widely used in treatment of mental disorders, stroke and extrapyramidal diseases and obtains the reliable therapeutic effect in clinical practice.

In Weisheng Baojian (Treasures on Health), the compatibility of Qihai (CV6) and Zusanli (ST36) was widely used in the medical cases treated with acupuncture and moxibustion. Through analyzing the medical cases and summarizing the rules of acupoint compatibility, it is found that LUO Tianyi's idea of moxibustion at these two acupoints was different from the other medical masters. He combined these two acupoints in line with "spleen and stomach theory", rather than from the perspective of the direct relationship of acupoints with syndromes and zangfu organs. It reflects the diversity in the understanding of the human body and diseases among medical masters. Therefore, in order to analyze the representative understandings of ancient medical masters on the connotation and rules of acupuncture and moxibustion, we cannot simply focus on the summary from acupuncture-moxibustion masters. It is suggested that the analysis should be expended in the entire field of traditional Chinese medicine to explore the general rules of treatment with acupuncture and moxibustion, investigate the differences, and deepen the basic reasons of the distinction.

This paper summarizes Professor SUN Yuanzheng's academic thought and clinical experience in treating diabetic retinopathy (DR) with yuan-primary and luo-connecting meridian-regulating acupuncture. Professor SUN considers that the fundamental cause of DR lies in visceral dysfunction, with stagnation in the ocular collateral vessels and impairment of the mysterious orifices being the core pathogenesis. He proposes the treatment model of "regulating viscera, unblocking ocular collaterals, and opening mysterious orifices" based on yuan-primary and luo-connecting meridian-regulating acupuncture. Yuan-primary and luo-connecting points are used to balance qi, blood, yin, and yang of the viscera. Baihui (GV20) is stimulated with transcranial repetitive acupuncture to activate the yang qi of the governor vessel and invigorate qi in the twelve meridians, improving systemic microcirculation. Combining this with stimulation of ocular areas, Fengchi (GB20), and periocular points, the stasis in the ocular collaterals are cleared and the mysterious orifices are unblocked, addressing both the root and manifestations of DR.

Zangxiang Jingmai Yuanliu Zeyin (Exploration of Origin and Development of Visceral Manifestations and Meridians) traces the historical origin for the development of the theories of visceral manifestation and meridians and in terms of the guiding principles and cultural background of these theories structured by the ancients. It chains the clues of the related knowledge development in Huangdi Neijing (the Yellow Emperor's Inner Classic) based on the rich historic literature. By interpreting the classics through history and in view of the specific humanistic perspective, the book exhibits the non-linear evolution track of the theoretical knowledge of visceral manifestation and meridians in the pre-Qin and Han dynasties. It is an important works in the field of acupuncture and humanities, and enlightens the cross-exploration of acupuncture, even in the circle of academic study of TCM and the humanities.

Zangxiang Jingmai Yuanliu Zeyin (Exploration of Origin and Development of Visceral Manifestation and Meridians) reveals that the theory of visceral manifestation and meridians of TCM is evolved with Tiandao (way of heaven) in different periods of ancient times. In the Warring States period, the "way of heaven" referred to yinyang and four directions, based on which, the manifestation of four viscera was developed. During the Qin and Han dynasties, six meridians were developed on the basis of six types of qi. In terms of "six types of qi and five elements", five zang, six fu and eleven meridians were structured in TCM. Corresponding to the twelve cycles of the ecliptic and celestial sphere, twelve meridians were composed. The book displays a particular style of research with rich quotations, and provides a new way of thinking for the study of ancient TCM books.

The paper introduces the investigation on the versions, herbal composition, indications and treatment of Taiyi Shenzhen (Taiyi Miraculous Pressing Moxibustion Technique with Herbal Moxa Stick). Taiyi Shenzhen Xinfa, written by HAN Yifeng in the Qing Dynasty, is the special book with this moxibustion technique recorded in the earliest time. But this book did not record the related herbal composition. In Taiyi Shenzhen, written by FAN Yuyi in the later time of the same dynasty, the herbal composition and the preparation of moxa stick were described in detail. There are many versions of this book, with various content contained. Nowadays, there are at least 4 versions of Taiyi Shenzhen, named, the re-carved version of the original block-printed edition of Taiyi Shenzhen of Yinxiang bookstore version; ZHOU Yonghe's block-printed edition, with the greatest influence and the most widely spread. In terms of the herbal composition, indications and treatment, this version is greatly different from those of Yinxiang bookstore version; and the reprinted version of Guansheng Pavilion in the 19th year of Jiaqing Emperor (1814) and the block-printed version of Hanmo hall in the 12th year of Tongzhi Emperor (1873). These two versions were less spread, and the herbal composition, indications and treatment were very close to those in the version of Yinxiang bookstore.

With the technological innovation and the advances in information technology, acupuncture-moxibustion is on the path of modernization and high-quality development. The research on ancient acupuncture-moxibustion literature has been gradually transformed from traditional sorting and digital research to intelligent knowledge services, so as to realize the deep integration of ancient acupuncture-moxibustion knowledge with the needs of modern clinical practice and scientific research. Guided by the characteristics of acupuncture-moxibustion knowledge and based on the knowledge meta-theory, the in-depth analytical indexing and knowledge organization are conducted on more than 400 kinds of ancient acupuncture-moxibustion literature. Taking ancient literature of meridian symptoms/manifestations as an example, thematic literature research and database construction are carried out. Integrated with database, cloud platform, knowledge domain mapping and other technologies, the sharing service platform of ancient acupuncture-moxibustion knowledge is constructed. As a result, the research and development achievements can be adopted by the researchers in the field of basic theory, clinical practice and research of acupuncture-moxibustion. Finally, through the way of "digital reconstruction + intelligent application", the path and paradigm of digital research of ancient acupuncture-moxibustion literature are explored to provide the references for the innovative utilization of ancient acupuncture-moxibustion literature.

The international dissemination of Chinese acupuncture represents a successful model of medical and cultural exchange between the East and the West, as well as an exemplary case of Chinese culture going global. In 1971, following the announcement by Xinhua News Agency that "acupuncture anesthesia technology had achieved success", American medical educator Professor Edmunds Grey Dimond became the first foreign doctor to visit China for an investigation of acupuncture anesthesia. His efforts significantly contributed to the promotion of Chinese acupuncture within western medical communities. From the perspective of acupuncture humanities, this article reviews and analyzes Dimond's academic background, his journey to study acupuncture anesthesia in China, and his unique insights into acupuncture, exploring how his open-minded and objective approach facilitated the acceptance and dissemination of acupuncture anesthesia and acupuncture techniques in the West.

The paper introduces 5 books written by WANG Mengying, including Suixiju Chongding Huoluan Lun, Guiyan Lu, Wenre Jingwei, Wang Mengying Yi'an and Suixiju Yinshipu; and analyzes the ideas of diagnosis and treatment of cholera and the academic thoughts in treatment with acupuncture-moxibustion therapy. In pathogenesis, cholera is classified into cold and heat types. Cholera of heat type roots on qi and blood. If the pathogenic factors are mild and located shallowly, the sneezing method, followed by scraping method, is adopted to open meridians and collaterals, as well as the qi level, so as to eliminate pathogens. When the pathogens go deeply, the bloodletting technique is used to clean the toxic heat in blood level and reduce the reversed qi. For cholera of cold type, warm ironing moxibustion is delivered to promote qi circulation and disperse cold, and improve qi movement. If spasm and syncope occur in cholera, no matter of cold or heat identification, the emergent measure is operated with the external application of pungent, warm and salty herbal plaster at Yongquan (KI1). When the pathogens are almost eliminated, the herbal medicines are combined to treat the symptoms and remove the causative factors of the disease.
