Fundus lesions mainly include retinal vascular disease, macular degeneration and retinal detachment, etc. They can be treated by surgery, and the degree of recovery from surgery depends on many factors, including the location of the lesion and the duration of the lesion.
1. Retinal vascular disease: retinal artery or vein obstruction causes fundus hemorrhage, for the vitreous volume of blood is large and not absorbed for more than 3-6 months, vitrectomy can be considered. The degree of vision recovery after surgery is related to the amount and location of the hemorrhage, and if it does not involve the macula, the patient’s eyesight can be more significantly improved.
2. Macular degeneration: patients with macular degeneration may suffer from obvious vision loss, visual distortion and visual field defects, etc. Patients can be treated by vitrectomy combined with macular endocardiectomy, after which the patients’ visual acuity can be improved to a certain extent, but complications such as secondary glaucoma and cataracts may occur.
3. Retinal detachment: retinal detachment is related to lattice-like degeneration, cystic degeneration and vitreous liquefaction and pulling in the peripheral part of the retina, etc. Patients may have black shadow in front of their eyes, blocked vision and sharp decrease in visual acuity, etc. Patients can be treated by surgery to reset the detached retina, and their visual acuity can be improved if they are treated in time. However, if the patient delays treatment, the surgical effect is generally poor.
It is recommended that patients with fundus lesions seek timely medical attention to assess their condition and follow medical advice.
