How long it takes to perform fundus hemorrhage surgery depends on the cause, location, amount and duration of bleeding and the skill of the surgeon, and can take several hours in severe cases. There are many causes that can lead to fundus hemorrhage, not all of them need to be treated surgically, and their severity varies with the difficulty of the surgery, so it is difficult to standardize the exact time needed for the surgery. If a patient with diabetic retinopathy in the proliferative stage has a large amount of hemorrhage, if the patient’s fundus proliferation and other conditions are mild, the operation time for removing the accumulated blood photocoagulation or freezing the bleeding point to stop the bleeding will be shorter, and it may take about one or two hours. If the occurrence of macular membrane pull or large area of retinal detachment pull and other causes of fundus hemorrhage, for the fragile broken retina and its cleanup time photocoagulation freezing and other scope is greater, the operation time can reach four or five hours and above. It is recommended that patients with fundus hemorrhage seek prompt medical attention to evaluate their condition and follow medical advice.
