PURPOSE: We report a case of cytomegalovirus (CMV) retinitis following placement of an intravitreal dexamethasone implant in an immunocompetent patient diagnosed with non-infectious uveitis. CASE SUMMARY: A 60-year-old woman was referred to our hospital for recurrent anterior uveitis. Fundus examination and fluorescein angiography showed dense vitritis, but no definite retinal infiltration. After laboratory examinations, the patient was diagnosed with non-infectious panuveitis. Uveitis was much improved after the patient started taking oral steroid medication. However, the patient complained of systemic side effects from the oral steroids. Medication was stopped, and an intravitreal dexamethasone implant was fitted to address worsening inflammation. Two months later, perivascular retinal infiltration developed and vitritis recurred. Viral retinitis was suspected, and the patient underwent diagnostic vitrectomy adjunctive with intravitreal ganciclovir injection. Polymerase chain reaction of vitreous fluid confirmed the diagnosis of CMV retinitis. The patient has remained inflammation-free for more than 20 months after vitrectomy, single ganciclovir injection, and 2 months of oral valganciclovir medication. CONCLUSIONS: This is a case report of CMV retinitis following placement of an intravitreal dexamethasone implant in an immunocompetent patient without any risk factors or previous history of immunosuppression. Potential risk factors for CMV retinitis should be evaluated and careful follow-up should be performed when intravitreal dexamethasone injections are unavoidable for the treatment of non-infectious uveitis.

A 14 year-old boy with acute lymphoblastic leukemia (ALL) on maintenance chemotherapy presented with vision-threatening cytomegalovirus (CMV) retinitis. Treatment with intavitreal ganciclovir injection (2 mg/0.1 mL) followed by oral ganciclovir resulted in successful resolution of CMV retinitis. Another 13 year-old boy with ALL on maintenance chemotherapy presented with prolonged fever with no response to antibiotics administration. CMV and real-time PCR revealed positive result and a titer of 2,618,700 copies/mL, respectively. Ganciclovir was used for more than the approved duration of treatment, but viral titer frequently recurred with elevated liver enzymes and fever. In these 2 cases of CMV infection, a high index of suspicion and prompt management is important in children receiving ALL chemotherapy.

Cytomegalovirus (CMV) infection is one of the most common congenital infections. The first case of discordant congenital CMV infection in twins occurred in Korea. A 31-year-old woman became pregnant with twins (dichorionic-diamniotic). An elective caesarean section was performed at 37 weeks. The first baby was male, weighing 2,410 g with an Apgar score of 8/9. The second baby was female, weighing 1,380 g with an Apgar score of 5/8. She had experienced intrauterine growth retardation, and presented with microcephaly, micrognathia, and joint stiffness. During the work-up for discordant twins, the second baby's serum test was positive for CMV immunoglobulin M. Her urine, blood, and cerebrospinal fluid (CSF) were CMV polymerase chain reaction positive. The first baby's CMV tests were negative. Ophthalmologic exam and audiometry performed on the second baby showed CMV retinitis and bilateral sensorineural hearing loss. She was treated with intravenous ganciclovir. Currently, she is bed-ridden and has significant developmental delay. Although the causes of discordant congenital CMV infection in twins are unclear, this case shows that discordant congenital CMV infection should be considered in twins with significant differences in intrauterine growth or clinical symptoms after birth.

PURPOSE: To study the treatment outcomes in patients who were administered multiple intravitreal ganciclovir injections more than 10 times alone without systemic anti-cytomegalovirus therapy for cytomegalovirus retinitis. CASE SUMMARY: A 64-year-old man who underwent immunosuppressive therapy after thymectomy due to an invasive thymoma and pure red-cell aplasia, a 60-year-old woman who underwent chemotherapy after diagnosis of diffuse large B-cell lymphoma, a 49-year-old man with a history of bone marrow transplantation due to acute myeloid leukemia, a 29-year-old woman with dermatomyositis treated with oral steroids and cyclosporine, and a 47-year-old woman who received intravitreal dexamethasone implant injections, intravitreal and subtenon steroid injections due to Behcet's disease were diagnosed with cytomegalovirus retinitis. All patients showed systemic complications such as pancytopenia after systemic anti-cytomegalovirus therapy, and therefore, they were administered multiple intravitreal ganciclovir injections alone. Best-corrected visual acuities improved in all patients, except in one case, where viral lesions were observed in the fovea. Retinal hemorrhaging and infiltrative lesions decreased in all patients. No severe complication was observed during the injection and in the follow-up period. CONCLUSIONS: Multiple intravitreal ganciclovir injections alone can be used as a treatment modality for cytomegalovirus retinitis to avoid the systemic side effects of systemic anti-cytomegalovirus therapy.

BACKGROUND/AIMS: Cytomegalovirus (CMV) surveillance and preemptive therapy is a widely-used strategy for preventing CMV disease in transplant recipients. However, there are limited data on the incidence and patterns of CMV disease during the preemptive period. Thus, we investigated the incidence and pattern of tissue-invasive CMV disease in CMV seropositive kidney transplantation (KT) and hematopoietic stem cell transplantation (HCT) recipients during preemptive therapy. METHODS: We prospectively identified patients with tissue-invasive CMV disease among 664 KT (90%) and 496 HCT (96%) recipients who were D+/R+ (both donor and recipient seropositive) during a 4-year period. RESULTS: The incidence rates of CMV disease were 4.1/100 person-years (4%, 27/664) in KT recipients and 5.0/100 person-years (4%, 21/496) in HCT recipients. Twenty-six (96%) of the KT recipients with CMV disease had gastrointestinal CMV, whereas 17 (81%) of the HCT recipients had gastrointestinal CMV and 4 (19%) had CMV retinitis. Thus, CMV retinitis was more common among HCT recipients (p = 0.03). All 27 KT recipients with CMV disease suffered abrupt onset of CMV disease before or during preemptive therapy; 10 (48%) of the 21 HCT recipients with CMV disease were also classified in this way but the other 11 (52%) were classified as CMV disease following successful ganciclovir preemptive therapy (p < 0.001). CONCLUSIONS: The incidence of CMV disease was about 4% in both KT and HCT recipients during preemptive therapy. However, CMV retinitis and CMV disease as a relapsed infection were more frequently found among HCT recipients.

Systemic infections that are caused by various types of pathogenic organisms can be spread to the eyes as well as to other solid organs. Bacteria, parasites, and viruses can invade the eyes via the bloodstream. Despite advances in the diagnosis and treatment of systemic infections, many patients still suffer from endogenous ocular infections; this is particularly due to an increase in the number of immunosuppressed patients such as those with human immunodeficiency virus infection, those who have had organ transplantations, and those being administered systemic chemotherapeutic and immunomodulating agents, which may increase the chance of ocular involvement. In this review, we clinically evaluated posterior segment manifestations in the eye caused by hematogenous penetration of systemic infections. We focused on the conditions that ophthalmologists encounter most often and that require cooperation with other medical specialists. Posterior segment manifestations and clinical characteristics of cytomegalovirus retinitis, endogenous endophthalmitis, toxoplasmosis, toxocariasis, and ocular syphilis are included in this brief review.

Cytomegalovirus (CMV) retinitis occurs predominantly in Human Immunodeficiency Virus (HIV) -infected patients. It was also reported in HIV-seronegative patients with systemic autoimmune disorder requiring systemic immunosuppression, organ or bone marrow transplantation, haematological or breast malignancy receiving chemotherapy, ocular diseases following intraocular or periocular corticosteroid injection, diabetes mellitus and Good syndrome. However, CMV retinitis in patients with concurrent dermatomyositis and malignancy has not been previously reported. It has not been reported in cancer other than haematological or breast malignancy, or in cancer patient prior to chemotherapy. We report a case of 40-year-old HIV-seronegative woman with underlying dermatomyositis and lung malignancy who developed right CMV retinitis which relapsed after recommencement of immunosuppressant. Both episodes of CMV retinitis were successfully treated after taken her immunocompromised state into consideration.
