The improvement of diagnostic levels for fundus diseases depend on the advancements of fundus imaging technology. Different fundus imaging technologies allow doctors to inspect ocular fundus from different aspects such as morphological or functional changes of retina. As a basic fundus examination method, optical coherence tomography provides highresolution and crosssectional retinal images coupled with noninvasive advantages. Fully understanding of the advantages and disadvantages of each fundus imaging technique, appropriate choosing one or combining several imaging techniques, and optimizing diagnostic procedures for each fundus disease are crucial steps to improve our diagnostic levels of ocular fundus diseases.
We have studied retrospectively 13 eyes with postoperative choroidal detachment of retinal detachment surgery in 126 cases(129 eyes).The frequency of choroidal detachment in this series is 10.1%(13/129).And we found that the middle-aged patients were more common sufferers,and drainaging the subretinal fluid,the extent of retinal degeneration and the buckling procedure might be the related factors to the occurence of postoperative choroidal detachment of retinal detachment surgery. （Chin J Ocul Fundus Dis,1993,9:210-213）
The treatment for retinoblastoma (RB) has been reached the stage of life-saving and vision-saving care. It is necessary to improve the survival rate and prolong the life time of RB children, retaining the eyeball and improving the quality of life. If the diagnosis is not timely and the treatment is inappropriate, the tumor recurrence, extraocular spread and metastasis of retinoblastoma will occur. The rate of eye protection and the survival chance of RB children will be reduced. With the continuous exploration of RB therapy and the emergence of new treatment methods, how to correctly select and evaluate these treatment methods and to adopt the most safe and effective treatment for RB children, to achieve long-term cure effect, is an important problem which clinicians need to consider.
In the research process of uveal melanoma (UM), the Collaborative Ocular Melanoma Study (COMS) is a landmark and outstanding clinical study. Its research conclusions are the foundation for today's UM clinical work and guidelines. COMS is the first and largest randomized clinical trials conducted to date, comparing the survival outcomes of two or more treatment regimens for primary malignant intraocular tumors with high reliability. Its research design, methods, and conclusions are still widely cited in this day. Learning from the research experience of COMS, summarizing research data based on Asian populations, and studying treatment methods suitable for Asian UM patients is a powerful supplement to COMS data, but also an expansion of this global research, further improving the level of UM diagnosis and treatment in China.
Immunogammopathy maculopathy is a newly discovered retinopathy associated with macroglobulinemia in recent years. The main manifestations were retinal vein convulsion and dilation caused by high blood viscosity, retinal interlaminar effusion and macular serous detachment. With the prolongation of the course of disease, the photoreceptor layer and RPE layer in the detachment area showed atrophic changes. The pathogenesis of ophthalmopathy is still unknown. Understanding the clinical features, diagnosis, differential diagnosis and treatment of ophthalmopathy is of great significance for understanding this kind of disease and improving the level of diagnosis and treatment of ophthalmopathy.
