Neovascular glaucoma (NVG) is a refractory disease, and it would be wrong to treat it simply as glaucoma. This article gives help from etiology, pathology, pathogenesis, early diagnosis and treatment. The main causes of neovascular glaucoma are diabetic retinopathy, ischemic central venous obstruction and ocular ischemic syndrome. Treatment first requires treatment of the cause, and then medication and surgery are available depending on the situation. Our own management: Follow-up examinations every 2-3 weeks for 8 months after the onset of the disease to check the anterior segment condition and intraocular pressure condition and atrial angle condition. Complete ocular evaluation and visual field examination every two months. We give different management depending on the situation. For the treatment of advanced patients with no light perception and unbearable ocular pain: we just perform postbulbar injections of chlorpromazine and lidocaine, which provide complete relief in more than 80% of patients, with some patients requiring repeat injections. We have not done cryosurgery or ocular removal for this disease for many years. Conclusion: The above treatments are generally manageable, although of course there are patients who cannot be controlled and eventually go blind. Usually patients have a gradual remission of the disease after 8 months and the whole treatment process takes 1-3 years.
