Disease Analysis: Subretinal hemorrhage is a serious eye disease. Due to the absence of any visible symptoms, it is often overlooked and delayed in treatment, potentially leading to blindness. The treatment course is usually long, and patients must take medication patiently to achieve healing or improvement.Clinical symptoms of subretinal hemorrhage:
1. Gradual blurring of vision, or the sensation of black shadows floating in the eyes, or sudden visual dimness upon waking up in the morning.
2. Normal external eye appearance, but fundus examination reveals vitreous opacity and bleeding in the retina.
3. The patient may have a history of myopia, hypertension, diabetes, retinal vascular occlusion, or trauma.
Advice: Subretinal hemorrhage is not an independent eye disease but rather a symptom shared by many eye diseases and certain systemic conditions. Clinically, it is generally referred to as retinal hemorrhage. The most common cause of retinal hemorrhage is capillary disease, primarily due to damage to the inner lining of capillaries, increased permeability, and blood leakage. The second most common cause is bleeding from veins, often occurring in localized or systemic conditions, such as delayed or stagnant venous blood flow, changes in blood viscosity, venous thrombosis, or inflammation of the venous walls. Bleeding from arteries is relatively rare and is usually associated with atherosclerosis or vascular embolism.
Many eye diseases can cause retinal hemorrhage. Common examples include retinal periphlebitis, retinal vein occlusion, senile disciform macular degeneration, optic disc vasculitis (venous occlusion type), traumatic retinal hemorrhage, hypertensive retinal arteriosclerosis, nephrotic retinal disease, diabetic retinal disease, leukemia, and changes in blood composition. Due to the varying causes of retinal hemorrhage, the prognosis and impact on vision differ.
A small amount of bleeding may fully absorb without affecting vision or causing other complications (e.g., hypertensive retinal hemorrhage, branch vein occlusion). If the bleeding is significant or recurrent, and blood enters the vitreous humor, causing vitreous opacity and the formation of proliferative vitreoretinopathy (e.g., diabetic retinal hemorrhage), vision will be severely impaired, potentially leading to blindness.
Treatment: If bleeding is substantial, early rest is recommended. The underlying disease should be treated, and medications to promote blood absorption should be taken. If the blood cannot fully absorb and leads to vitreous proliferation, vitrectomy may be necessary.
Prognosis and Care: If pain, dryness, itching, blurred vision, or prolonged congestion occurs, seek medical attention promptly. If only bleeding symptoms are present, apply cold or warm compresses to the eyes for the first two days after bleeding. Use eye drops that constrict blood vessels. Maintain regular bowel movements. Rest with closed eyes and reduce computer use. Avoid staying up late. Significant improvement should be observed within three days, with the congested area shrinking from bright red to dark red, and recovery can typically occur within a week.
