The main purpose of funduscopic examination is to detect the condition of vitreous, retina and choroid, so that early detection and treatment can be avoided. Fundus examination usually uses fundoscopy, fundus fluorescence angiography to understand the condition of the patient’s retina, vitreous body and choroid, and to observe whether there are any abnormalities occurring. Only through a detailed fundus examination to confirm the diagnosis of the current fundus disease, can we take the appropriate treatment to promote the recovery of the disease. Patients with vitreous hemorrhage, retinal degeneration, macular degeneration, retinal detachment and other eye diseases need to undergo a fundus examination to assess the severity of the patient’s condition and determine the treatment plan. It is recommended that patients with fundus lesions seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
