The only consistent method of antibioprophylaxis in this instance is a solution of povidone-iodine applied pre-injection. Treatment
The patient needs urgent examination by an ophthalmologist, preferably a vitreoretinal specialist who will usually decide for urgent intervention to provide intravitreal injection of potent antibiotics. Injections of vancomycin (to kill Gram-positive bacteria) and ceftazidime (to kill Gram-negative bacteria) are routine. Even though antibiotics can have negative impacts on the retina in high concentrations, the facts that visual acuity worsens in 65% of endophthalmitis patients and prognosis gets poorer the longer an infection goes untreated make immediate intervention necessary. Endophthalmitis patients may also require an urgent surgery (pars plana vitrectomy), and evisceration may be necessary to remove a severe and intractable infection which could result in a blind and painful eye. Steroids may be injected intravitreally if the cause is allergic. In patients with acute endophthalmitis, combined steroid treatment with antibiotics have been found to improve visual outcomes, versus patients only treated with antibiotics, but any improvements on the resolution acute endophthalmitis is unknown.

A hypertensive emergency is very high blood pressure with potentially life-threatening symptoms and signs of acute damage to one or more organ systems (especially brain, eyes, heart, aorta, or kidneys). It is different from a hypertensive urgency by this additional evidence for impending irreversible hypertension-mediated organ damage (HMOD). Blood pressure is often above 200/120 mmHg, however there are no universally accepted cutoff values. Signs of organ damage will be discussed below. Signs and symptoms
Symptoms may include headache, nausea, or vomiting. Chest pain may occur due to increased workload on the heart resulting in inadequate delivery of oxygen to meet the heart muscles metabolic needs. The kidneys may be affected, resulting in blood or protein in the urine, and acute kidney failure. People can have decreased urine production, fluid retention, and confusion.Other signs and symptoms can include:
Chest pain
Abnormal heart rhythms
Headache
Nosebleeds that are difficult to stop
Dyspnea
Fainting or the sensation of the world spinning around them (vertigo)
Severe anxiety
Agitation
Altered mental status
Abnormal sensationsThe most common presentations of hypertensive emergencies are cerebral infarction (24.5%), pulmonary edema (22.5%), hypertensive encephalopathy (16.3%), and congestive heart failure (12%). Less common presentations include intracranial bleeding, aortic dissection, and  pre-eclampsia or eclampsia.Massive, rapid elevations in blood pressure can trigger any of these symptoms, and warrant further work-up by physicians. Physical exam would include measurement of blood pressure in both arms.
