Endogenous endophthalmitis is an uncommon secondary infection caused by prostatic abscess. We present a case of a 37-year-old male patient presenting with left endophthalmitis whose source being a prostatic abscess.

A 37-year-old Asian man with no known medical history visited our hospital with left eye vision loss. The patient had been suffering from fever and micturition difficulty for a week. Computed tomography (CT) detected severe inflammation in the anterior chamber of the left eye and pulmonary embolism in the lung. The ophthalmology department diagnosed endophthalmitis with a retinal white lesion in the fundus. A urine test showed pyuria and bacteriuria. CT also showed a prostatic abscess. Klebsiella pneumoniae was detected in the blood and urine cultures. The patient was referred to the urology department and systemic antibiotic treatment with ceftriaxone was started. His lower urinary tract symptoms had improved and no residual urine was confirmed. The treatment included the addition of levofloxacin, considering the prostatic abscess. CT scan findings on the 16th day of his hospitalization showed both endophthalmitis and the prostatic abscess had improved. Although his eyesight did not recover, his general condition was good and discharged on the 31st day of his hospitalization.

Prostatic abscess commonly occurs as a complication of poorly treated bacterial prostatitis. The most common organism causing prostatic abscesses is Escherichia Coli, followed by Klebsiella pneumoniae. Prostatic abscesses can cause secondary infection through the bloodstream. There are few reports of concurrent endophthalmitis and prostatic abscess, however, former reports of endophthalmitis with a prostatic abscess show vision loss after treatment. In this case, incision, drainage, and antibiotics injection into the eyeball was performed, however, the patient’s vision did not recover.

We presented a case report of a patient who had a prostatic abscess which is causative for endophthalmitis and pulmonary embolism through bloodstream. The prognosis for vision recovery in cases of prostatic abscess complicated by endophthalmitis is extremely poor, therefore it is important to provide prompt and appropriate treatment for prostatitis and prevent the development of prostate abscesses.
