In addition to its role as a sex hormone, estrogen aff ects the struc ture and function of many other systems such as the bone, the cardiovascular and the nervous system. Here, we review the most recent supporting evidence for es trogen as an important player in ocular fundus diseases, focusing particularly o n the effects of estrogen on these diseases and the underlying mechanisms. Base d on this, we also discuss the clinical applicability of estrogen in treating va rious agerelated disorders including agerelated macular degeneration and ret in al neurodegeneration. Our growing understanding of estrogenmediated action at a molecular level will provide insight into the controversies surrounding hormon e replacement therapy.
Chronic disease is a major threat to human health. Fundus disease has become a major ophthalmic disease affecting daily life. Although great breakthroughs have been made in the treatment, compared with other chronic disease management, the management of patients with fundus disease is still in its infancy. To strengthen the management exploration of patients with fundus diseases, establish a management model of fundus diseases and strive to improve patients' awareness of fundus diseases and adherence to treatment and follow-up are the great challenges at present. All ophthalmic centers should strengthen patient education, establish a regional cooperation network, support the construction of grassroots medical capacity, cultivate talents, enhance training, promote the standardized treatment of fundus diseases, standardize fundus imaging inspection and diagnosis, and promote the homogeneous construction of diagnosis and treatment of chronic fundus diseases. We will accelerate the construction of a hierarchical diagnosis and treatment system and the ability to link consultation and referral. Through systematic management and intervention of fundus diseases, a large number of patients with fundus diseases will receive early screening, diagnosis, standardized continuous treatment and systematic management, and improve the quality of life of patients with fundus diseases.
Objective Observation on the characteristics of choroidal melanomas with indocyanine green angiography (ICGA) and fundus fluorescsin angiography(FFA). Methods Both ICGA and FFA were used in 16 cases of choroidal melanoma for comparison and analysis. Results 81.2% of tumors showed hypofluorescence all the way or faint fluorescence in later stage．62.6% of tumors had characteristic intrinsic tumor vassels with ICGA,while 12.5% of tumors had intrinsic vessels with FFA．Those tumors that can't be diagnosed owing to whole hyperfluorescence in later stage with FFA may be diagnosed by visibility of intrinsic tumor vessels with ICGA. Conclusion ICGA is helpful in the diagnosis of choroidal melanoma. (Chin J Ocul Fundus Dis, 2000，16：3-5)
Based on the current situation of patients with retinal diseases in China and the clear requirements of the "14th Five-Year Plan for Eye Health (2021-2025)" to strengthen the construction of the prevention and control system for retinal diseases, experts in the field of retinal diseases in China have conducted in-depth and comprehensive thematic discussions, and used the modified Delphi method for collective decision-making and opinion solicitation, ultimately forming consensus and consistent guidance suggestions for the management of chronic diseases of retinal diseases that are in line with China's national conditions. This consensus includes key content such as definitions, treatment plans, and follow-up frequency for the management of chronic diseases of the fundus. It clearly proposes relevant measures to improve the management process of chronic diseases of the fundus, and elaborates on the advantages and feasibility of establishing an online remote platform for the management of chronic diseases of the fundus, in order to assist doctors in formulating personalized treatment plans and ensure that patients receive standardized treatment and follow-up. This consensus will provide guidance and reference for the management of chronic diseases and long-term standardized diagnosis and treatment of major fundus diseases in China.
