Vitreous hemorrhage loss of vision to light perception may be caused by factors such as ocular trauma, fundus lesions, and ocular tumors.
The vitreous itself is not vascularized and does not bleed. However, patients with ocular trauma may bleed intraocularly due to damage to blood vessels within the choroid, retina, and other intraocular tissues, and when blood enters the vitreous body, the patient may develop vitreous hemorrhage. Patients with vitreous hemorrhage may experience vision loss because the hemorrhage blocks light from entering the retina.
Vitreous hemorrhage can also occur in patients with retinopathy because of damage to the retinal blood vessels, such as central retinal vein occlusion, retinal vein periphlebitis, and proliferative diabetic retinopathy. In addition, vitreous hemorrhage can also occur in patients with ocular tumors, such as retinal hemangioma and choroidal melanoma.
It is recommended that patients with vitreous hemorrhage seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
