Cytomegalovirus-related uncontrolled glaucoma in an immunocompetent patient: a case report and systematic review.

backgroundCytomegalovirus can cause ocular anterior uveitis with ocular hypertension. Basis on the therapy, ocular pressure usually can be controlled. We report a case of a man who had unilateral cytomegalovirus anterior uveitis with refractory glaucoma during the process of treatment. CASE PRESENTATION: A 57-year-old man who was diagnosed Posner-Schlossman syndrome and was admitted for repeatly attacks of raised IOP in left eye for 4 months. We found the cytomegalovirus -DNA was high (1800 copies/ml) in his aqueous. After systemic used of antiviral drug accompany with topical used of anti-inflammation, anti-glaucoma agents and genciclovir gel, the ocular pressure was dropped to normal. While the pressure elevated again in a month after stopping systemic antiviral treatment. Furthermore, the second test showed cytomegalovirus in aqueous humor decreased to 526 copies/ml. Intravenous drugs to antiviral, anti-inflammatory and anti-glaucoma were applied, but the ocular pressure was still high. In the progression of glaucomatous damage in the eye, glaucoma surgery was operated with no cytomegalovirus was detected. At last, the postoperative ocular pressure has been controlled.

conclusionsCMV infection is not rare. Patients have unilateral mild anterior inflammation with relapsed attacks of elevated intraocular pressure should be considered for CMV infection. We found that concurrent use of systemic and topical ganciclovir in a short period could reduce ocular CMV significantly, while ocular hypertension recurred. The antiviral treatment should be individualized. Glaucoma surgery could be offered to protect CEC loss and glaucomatous damage.
