Cytomegalovirus (CMV) retinitis usually affects severely immunosuppressed individuals. We report two immunocompetent patients who developed CMV retinitis.
Case 1 was a 65-year-old man who was referred to us with blurred vision and floaters of 2 weeks duration in his left eye. Slit-lamp biomicroscopy showed keratic precipitates, aqueous cells, and vitreous opacity in his left eye. Funduscopic examination revealed yellow-white retinal lesions with arterial sheathing in the superotemporal midperiphery. Case 2 was a 63-year-old man who presented with a 2-week history of blurred vision in his left eye. Ophthalmologic examination of the left eye showed keratic precipitates, aqueous cells, vitreous opacity, and yellow-white lesions in the superotemporal peripheral retina. In both cases, CMV DNA was detected in the aqueous humor and therefore the diagnosis was CMV retinitis. CMV retinitis in both cases was indolent and was resolved in one month without treatment with antiviral drugs. Although both patients had diabetes mellitus, the results of their laboratory examinations were unremarkable and they were immunocompetent.
Unlike CMV retinitis in immunocompromised patients, CMV retinitis in immunocompetent patients had significant anterior and vitreous inflammation but did not require antiviral treatment. A possible association between CMV retinitis and diabetes mellitus was suggested.

    • "According to previous reports, the ocular prognosis of CMV retinitis in immunocompetent patients is not serious, and the retinitis can usually be treated successfully by administration of ganciclovir and/or valganciclovir.2–5,7 There have also been reports of some cases that did not require antiviral treatment and others in which retinitis has resolved spontaneously with steroid eye drops.6,8 Our patient had undergone an intensive course of antiviral treatment with intravitreous ganciclovir and oral valganciclovir, but the retinitis did not resolve, and 14 months after his initial ocular symptoms, colon cancer metastasis to the liver was detected.

    ABSTRACT: We report a case of cytomegalovirus (CMV) retinitis in an immunocompetent patient who was resistant to antiviral treatment, and in whom fatal metastatic liver cancer was later detected. A 74-year-old Japanese man visited our ophthalmology clinic in May 2011. He had a history of well controlled type 2 diabetes and colon cancer, and underwent successful surgical treatment in 2008. In April 2011, he was diagnosed with uveitis affecting his left eye and received posterior sub-Tenon injection of triamcinolone acetonide. He was referred to us because of aggravation of the retinal lesion. Funduscopic examination of the left eye revealed arcuate, whitish, necrotizing retinitis with hemorrhage along the temporal arcade of the retina. Polymerase chain reaction of the aqueous fluid was positive for CMV DNA. Because of diagnosis of CMV retinitis in his left eye, he was referred to an internist and investigated for systemic CMV infection or any serious disease which could cause immunocompromise, but neither was detected. Despite an intensive course of intravitreous ganciclovir and oral valganciclovir, the retinitis did not resolve. In June 2012, 14 months after the initial ocular symptoms, metastatic liver cancer was found and the patient passed away. When CMV retinitis is resistant to antiviral treatment or recurs in an immunocompetent patient, it is important that ophthalmologists undertake systemic investigation for occult malignancy.

    ABSTRACT: To assess corneal scrapings and aqueous humor samples analyzed by polymerase chain reaction (PCR) that were positive for cytomegalovirus (CMV) in patients with keratitis of unknown origin and to investigate their clinical manifestations. Retrospective, interventional case series. Seventy-eight patients with epithelial (n=37), stromal (n=12), or endothelial keratitis (n=29) of unknown origin examined at the Osaka University Medical Hospital. Clinical examination and tears, corneal scrapings, and aqueous humor specimens were evaluated by real-time PCR for CMV. Quantification of CMV DNA at the diagnosis of each type of keratitis with unknown origin and monitoring during the therapeutic course for CMV-positive cases. No cases of epithelial or stromal keratitis had CMV DNA. Seven of 29 corneal endotheliitis cases (24.1%) were positive for CMV. Cytomegalovirus-positive cases of corneal endotheliitis characterized by localized corneal edema and keratic precipitates included 4 patients who had undergone penetrating keratoplasty and were refractory to the treatment for graft rejection and 3 patients with idiopathic endotheliitis. Cytomegalovirus DNA copy numbers were estimated and ranged from 6.3x10(4) to 3.6x10(6)/ml. In all positive cases, the numbers of CMV DNA copies decreased within weeks during treatment with systemic and topical ganciclovir (GCV) combined with a topical steroid. Five eyes (62.5%) had clinical improvement. In cases of endothelial keratitis, diabetes mellitus was significantly higher in patients positive for CMV (71.4%) than in patients negative for CMV (18.2%, P=0.016, chi-square test). A total of 24.1% of cases with corneal edema of unknown origin were CMV positive and should be included in the differential diagnosis of idiopathic corneal endotheliitis or graft edema after penetrating keratoplasty, especially for bullous keratopathy. Real-time PCR for CMV, based on the diagnosis and monitoring of the clinical course, may be useful. Cytomegalovirus corneal endotheliitis requires early appropriate treatment using GCV. Because clinical remission after GCV may depend on the area of normal endothelium, early diagnosis and therapy are important for CMV corneal endotheliitis.

    ABSTRACT: determined. 5 Although the prognosis of Nocardia-associated endogenous endophthalmitis is generally considered to be relatively poor, our case showed that a prompt diagnosis followed by appropriate treatment can improve the ocular outcome as well as reduce the associated morbidity and mortality.
