Fundus hemorrhage is not an independent eye disease, but a feature shared by many eye diseases and certain systemic diseases. It is commonly seen in retinopathy due to hypertensive retinopathy, diabetes mellitus and nephropathy. Retinal perivasculitis, retinal vein obstruction, optic disc vasculitis, and hematologic diseases cause retinopathy, and fundus hemorrhage from ocular trauma. Due to various etiologies leading to the same pathological damage, such as retinal hemorrhage, exudation, microangioma, neovascularization, etc. This disease has a long course and is prone to recurrent attacks because of its complex etiology, which seriously affects vision and causes many serious complications. Such as macular lesion (macular cystoid edema, macular degeneration), neovascular glaucoma, vitreous hemorrhage, optic nerve atrophy, proliferative retinopathy, retinal detachment, if not timely and effective treatment, can often lead to blindness. (1) mechanical obstruction, such as thrombosis; (2) inflammatory disease or immune complex invasion of the vessel wall, such as retinal perivasculitis, optic disc vasculitis, etc.; (3) systemic vascular disease and hematologic disease, such as hypertension, diabetes mellitus, etc. retinopathy; (4) retinal vascular abnormalities, various causes lead to the same pathological damage, such as retinal hemorrhage, exudation, microangioma, neovascularization, etc. (5) The eye is affected by external forces. Presentation of fundus hemorrhage (1) Sudden darkness in front of the eyes, with only manual or light perception. (2) Suddenly, there is a round black shadow in front of the eye, which does not float with the eye rotation, and the object is completely missing in the direction of the center, while the objects on the sides are blurred and visible. (3) Suddenly, there is a black shadow like a line in the eye that shoots straight in a certain direction, progressing rapidly and gradually increasing in number, finally covering the front of the eye and blurring the vision, unable to distinguish. (4) Suddenly there is a flash of red light in front of the eyes, which gradually increases, resulting in red light all over the eyes and unclear vision. (5) The onset of the disease is usually preceded by a feeling of eye swelling and eye fluttering. (6) Most of them have recurrent attacks, and each attack also has some of the above symptoms, and even if the accumulated blood does not subside, when the bleeding continues, there may be some of the above sensations. The prognosis and the impact on the patient’s vision are different due to the different causes and locations of fundus bleeding. If the hemorrhage is small and located in the optic papilla and the peripheral part of the retina, there may be no obvious symptoms. If the hemorrhage is large, the patient may feel a black shadow floating in front of his eyes and his vision is partially or completely blocked, leaving only a sense of light vision. If the hemorrhage is located in the center of the retina (macular area) the patient loses central vision, i.e., the central area has dark shadows obscuring the vision, and the periphery still has partial vision. Treatment At present, the treatment of this disease in western medicine mainly adopts laser therapy, fibrinolytic and anti-platelet coagulant. These can treat the existing neovascularization and control the disease, but cannot prevent the formation of new neovascularization, further absorption of stagnant blood, restore vision, and prevent recurrence of the disease, which is far less desirable than Chinese medicine. It is possible to use laser and western medicine at the same time, as well as in the process of disease recovery, to strive for more opportunities to use Chinese medicine to achieve the effect of both the symptoms and the root cause.
