Abstract
Purpose: To assess the long-term safety and clinical outcomes of a ganciclovir intravitreal implant in patients with cytomegalovirus (CMV) retinitis. Methods: A retrospective study was performed of patients with CMV retinitis treated with a ganciclovir intravitreal implant. Results: The study included 13 patients (16 eyes) previously treated with a ganciclovir intravitreal implant. The mean time since the last implant placement was 21.3 years and the mean total duration of follow-up, 22.7 years. Visual acuity (VA) ranged from 20/25 to light perception, with 56% of eyes maintaining a VA of 20/60 or better at the most recent follow-up examination. Common ocular complications included epiretinal membrane (38%), macular fibrosis/scarring (25%), retinal detachment (RD) (25%), implant dislocation (25%), and immune reactivation uveitis (19%). Intraocular surgery was required in 10 eyes (63%), with the most frequent being cataract extraction (31%), pars plana vitrectomy (PPV) for implant removal (19%), and PPV for RD (13%). Conclusions: Results show the long-term safety of the ganciclovir intravitreal implant despite its residual inactive inert shell. Complication rates are consistent with those expected from infectious sequelae.

Abstract
BACKGROUND Viral retinitis composes a group of infectious ocular diseases with poor prognoses. With the advent of antivirals and HAART, the treatment of these diseases has evolved and ocular outcomes have improved. However, even with prompt medical treatment, a significant number of patients will experience complications that require surgical intervention. While there has been an abundance of research examining the medical treatment of CMV retinitis and acute retinal necrosis, the research examining surgical outcomes of complications such as retinitis-associated retinal detachment is comparatively limited. METHODS Literature review. RESULTS In this review, we discuss the current literature examining treatment of CMV retinitis and acute retinal necrosis, with a focus on surgical management of complications such as retinal detachment. CONCLUSIONS Despite significant improvements in the medical treatment of CMV retinitis and ARN over the last three decades, vision-threatening complications such as retinal detachment are relatively common and require surgical management via PPV, laser photocoagulation, and intraocular gas or silicone oil tamponade.

Abstract
Since the introduction of combination antiretroviral therapy (cART) in Japan in 2008, the spectrum of ocular manifestations in patients with human immunodeficiency virus (HIV) has changed. This study, conducted at Tokyo Medical and Dental University Hospital between January 2012 and August 2023, aimed to understand the epidemiology and clinical features of ocular manifestations in patients with HIV during the cART era. Of the 218 patients diagnosed with HIV, 23 (10.55%) exhibited ocular manifestations; all were male, aged 32-73. The most prevalent ocular complication was uveitis (60.67%). Notably, the prevalence of uveitis in this cART era has surged compared to earlier Japanese studies. Our data also suggest a potential direct link between uveitis and HIV, particularly in patients who have not yet undergone cART. However, cytomegalovirus retinitis, another prevalent ocular disease in our study, appeared more strongly associated with patients who commenced cART. Neither ocular condition was significantly correlated with CD4+ T-cell count. Importantly, our observed ocular manifestation prevalence (10.55%) was lower than that in previous studies, emphasizing the potential influence of cART and national healthcare support. These findings provide unique insights into the evolution of ocular manifestations in patients with HIV in Japan amidst cART availability.

Abstract
PURPOSE To clarify the cut off value of blood CMV load to indicate CMV retinitis and its relationships with ocular features. METHODS Patients were divided into non-CMV and CMV retinitis groups. A logistic regression model was applied to estimate the association of each variable with CMV retinitis. Spearman correlation was used to estimate the correlation between the blood and aqueous CMV load. RESULTS Blood CMV load higher than 4log10 (OR, 6.897; CI: 2.813-16.910; P < .001) was the major predictor of CMV retinitis. Blood CMV load wasn't different between the initial and early stage (P = .066). No correlation was observed between the blood and aqueous CMV load (P = .083, r = 0.228). CONCLUSIONS Blood CMV load higher than 4log10 is an important predictor for CMV retinitis in HIV/AIDS patients, but it couldn't indicate the ocular features. Ophthalmologic screening is still necessary.Abbreviations: CMV: Cytomegalovirus; CMVR: Cytomegalovirus retinitis; HIV: Human Immunodeficiency Virus; AIDS: Acquired Immune Deficiency Syndrome; ART: Antiretroviral therapy; EOD: End-organ diseases; PCR: Polymerase Chain Reaction; OR: Odds Ratio; CI: 95% Confidence Interval; IQR: Interquartile range.

Abstract
While socioeconomic disparities impact clinical care and patient outcomes, their impact on the anatomic and visual outcomes of retinal detachment in patients with viral retinitis is unstudied. This case series included 18 eyes in 18 patients from a single academic institution between January 1, 2008 and December 31, 2018. Patient characteristics including age, sex, race, ethnicity, insurance, immunosuppression, viral retinitis, retinal detachment, retinal detachment repair, visual and anatomic outcomes, missed appointments, and Area Deprivation Index [ADI] were collected. The low-ADI group, indicating less socioeconomic disadvantage, was comprised of twelve patients with national ADIs less than 38, and the high-ADI group of six patients with national ADIs greater than 38. High-ADI patients tended to be younger (average age 38.0 versus 51.3; P = 0.06), of female sex (P = 0.03), and had more missed appointments (median 11.0 vs 0; P = 0.002). A similar number of patients in both the high-ADI and low-ADI groups underwent pars plana vitrectomy alone or pars plana vitrectomy with scleral buckle. Visual acuity was similar in the high-ADI group than in the low-ADI group at baseline, but worse at the final follow-up visit (P = 0.004). Post-operative and final visit ocular hypotony were more common in the high-ADI group (P = 0.02). In our series, socioeconomic disadvantage negatively affects the visual outcomes in patients with viral retinitis associated-retinal detachments. These factors should be considered by ophthalmologists when treating these patients.

Abstract
Cytomegalovirus (CMV) retinitis is an opportunistic infection that has traditionally affected those who have HIV/AIDS or immunosuppressed individuals. CMV retinitis previously infected one-third of AIDS patients in the pre-highly active antiretroviral therapy (HAART) era, but since HAART, Western countries have seen an 80% decrease in the incidence of the disease. More recently, CMV retinitis has been reported in patients who are immunosuppressed, often due to chemotherapy or immunomodulatory medications. The diagnosis of CMV retinitis is often suspected based on clinical findings, with polymerase chain reaction for confirmation of CMV, especially in atypical cases. Highly active antiretroviral therapy and anti-CMV medications (systemic or local) remain the mainstay of treatment. However, for those who are not responsive to HAART, CMV retinitis remains a challenge, and can still lead to significant vision loss. Moreover, a regimen of anti-CMV medications can sometimes lead to viral resistance or organ toxicity. Complications such as immune recovery retinitis and rhegmatogenous retinal detachments continue to threaten the vision of patients who develop CMV retinitis. These complications can arise following initiation of treatment or if patients show disease progression. Proper vision screening for CMV retinitis in immunosuppressed patients at-risk is necessary for early detection and treatment.

Abstract
Purpose The aim of this study was to describe the clinical features, course, and clinical outcomes of eyes with cytomegalovirus (CMV) retinitis in immunosuppressed patients of different etiologies. Methods This was a retrospective observational study from a single ophthalmic tertiary care center. The patients included referrals from the nodal cancer center and the local human immunodeficiency virus (HIV) treatment clinic. Demographics, history, visual acuity, ocular features, treatment protocol, and final visual outcome of patients who were diagnosed with CMV retinitis in the period of five years from 2014 to 2019 were studied. Results CMV retinitis was diagnosed in 25 eyes of 14 patients. Age of the patients ranged from 11-54 years. Ten (71.43%) patients were male and four (29.57%) were female. Eight of them had acute lymphoblastic leukemia (ALL), four were suffering from HIV infection and one patient each had lymphoma and history of a kidney transplant. The treatment for CMV retinitis ranged from two to sixty weeks depending on disease activity and systemic condition. Three of the patients were on maintenance therapy for ALL at the time of reactivation. Conclusion Duration of treatment for CMV retinitis in patients of ALL was longer as compared to the other etiologies, and in recurrences, it needed to be continued till the completion of maintenance therapy for ALL. It is prudent to advise regular ophthalmic screening of all immunocompromised patients, as they are at a high risk of developing CMV retinitis. Patients of ALL, especially while on maintenance therapy, should be monitored for possible development or reactivation of CMV retinitis.

Abstract
AimsTo determine if early dilated fundus examination for cytomegalovirus (CMV) retinitis leads to better visual outcomes in areas with limited HIV care, where patients may have long-standing retinitis before they are diagnosed with HIV.MethodsTwenty-four eyes of 17 patients with CMV retinitis who were seen at an urban HIV clinic in Chiang Mai, Thailand, were included in this retrospective cohort study. Participants were divided into two groups based on the amount of time from the first documented CD4 count below 100 cells/mm3 to the first eye examination for CMV retinitis. Average visual acuity in each group was calculated at the time CMV retinitis was first detected, and then at 3, 6 and 12 months after diagnosis.ResultsThe group of patients who received an eye examination within approximately 4 months of the initial low CD4 count measurement had better baseline visual acuity (median 20/30,IQR 20/20 to 20/60) compared with patients who presented later (median 20/80, 20/60 to hand motion); p=0.03). Visual acuity did not change significantly during the 12-month study period in either the early group (p=0.69) or late group (p=0.17).ConclusionIn this study, patients who were examined sooner after a low CD4 count had better vision than patients who were examined later. Routine early screening of patients with CD4 counts under below 100 cells/mm3 may detect earlier disease and prevent vision loss.

Abstract
PURPOSE OF REVIEW Ophthalmologic conditions were among the earliest described findings in patients with the acquired immunodeficiency syndrome (AIDS). The purpose of this review is to highlight recent changes in the pathophysiology and management of ophthalmologic conditions in patients infected with the human immunodeficiency virus (HIV). RECENT FINDINGS The introduction of highly active antiretroviral therapy (HAART) in 1996 changed ophthalmologic findings from predominantly acute infectious diseases to chronic, slowly progressive, debilitating conditions. HIV-associated neuroretinal disorder infrequently leads to blindness, but it causes visual disability in a large percentage of patients. Cytomegalovirus retinitis is now seen less commonly in the USA, but it remains an important cause of blindness in HIV-infected patients from developing countries. Immune recovery uveitis has emerged as a major cause of visual disability in the USA. As HIV has become a chronic disease, visual disability due to chronic noninfectious diseases have become increasingly important.

Abstract
BACKGROUND Retinal cytomegalovirus (CMV) infection is a common opportunistic infection and remains a significant contributor to visual loss in patients with AIDS. We highlight the poor outcomes of CMV retinitis in three HIV-infected patients who were initiated on antiretroviral therapy (ART). We conducted a retrospective chart review of advanced stage HIV-infected patients with known CMV retinitis.Case 1. A 37-year-old man, with a CD4+ cell count of 35 cells/µL, presented for ART initiation with a 5-month history of visual loss in his left eye. Fundoscopy showed left eye CMV retinitis and right eye HIV retinopathy. ART and 5 months of weekly intravitreal ganciclovir injections (left eye) were commenced. Six-month outcomes included virological suppression, and visual acuity in the right eye of 6/6 and in the left eye of 3/60.Case 2. A 31-year-old woman, with a CD4+ cell count of 39 cells/µL and on tuberculosis therapy, presented for ART initiation. She presented with a 2-month history of decreased visual acuity. Fundoscopy showed bilateral CMV retinitis, which was more pronounced in the left eye. ART and 8 months of intravitreal ganciclovir injections were commenced. Six-month outcomes included virological suppression and visual acuity in the right eye of 6/9, and in the left eye of 6/24.Case 3. A 29-year-old woman, with a CD4+ cell count of 24 cells/µL, who was on tuberculosis therapy and ART, complained of blurred vision at her 2-month ART follow-up visit. Fundoscopy showed bilateral retinal detachment secondary to CMV retinitis. While silicone oil tamponade and subsequent retinectomy successfully repaired the right eye, extensive damage rendered the left eye irreparable. Six-month outcomes included virological suppression, with 6/120 visual acuity in the right eye and complete blindness in the left eye. CONCLUSION CMV retinitis causes debilitating, permanent sequelae, which is preventable by ART initiation at higher CD4+ cell counts. Despite achieving virological suppression, vision could not be completely restored in these patients, irrespective of the severity of CMV retinitis.

Abstract
PURPOSE To identify determinants of adverse outcomes in acute retinal necrosis (ARN), presenting characteristics and incidence rates of vision loss and ocular complications in a cohort of polymerase chain reaction (PCR)-positive eyes were analyzed. DESIGN Retrospective observational cohort study. METHODS Forty-one eyes of 36 patients with clinically diagnosed ARN, PCR-positive for herpes simplex virus or varicella zoster virus and evaluated between January 2002 and June 2013, were included. Main outcome measures included incidence rates of vision loss and retinal detachment (RD). RESULTS Presenting visual acuity was generally poor (20/50 to >20/200 in 27%; 20/200 or worse in 56%). The incidence rate of ≤20/200 was 0.66/eye-year (EY), (95% confidence interval [CI], 0.32/EY to 1.22/EY); the rate of light perception or no light perception vision was 0.07/EY (95% CI, 0.02/EY to 0.16/EY). During follow-up, 59% of eyes developed at least 1 RD (rate = 0.40/EY, 95% CI, 0.19/EY to 0.58/EY). Eyes with retinitis involving ≥25% of the retina at presentation detached at nearly 12 times the rate, as compared to those with <25% retinal involvement (0.70/EY vs 0.06/EY; P = .001). Development of an RD was the greatest determinant of adverse visual outcomes, with 4% of eyes, that had experienced at least 1 RD, achieving a best-corrected visual acuity of ≥20/40 compared to 53% of eyes that never detached (P = .0003). CONCLUSIONS Poor outcomes in ARN were common in this cohort. RD confers the greatest risk of incident vision loss, and once 25% or more of the retina is involved the risk of RD and visual loss increases significantly.

Abstract
As CMVR continues to affect HIV-positive and non-HIV immunosuppressed patients, ophthalmologists must continue to tailor diagnostics and therapeutics to individual cases. In HIV-related disease, ocular fluid sampling and intravitreal drug delivery are considerations, but systemic antiviral therapy is paramount in the initial management from both ophthalmic and systemic morbidity standpoints. Non-HIV-related disease should be approached with a multidisciplinary team, including an ophthalmologist/vitreoretinal/uveitis specialist for consideration of intravitreal antiviral therapy with qualitative and quantitative aqueous PCR monitoring, and consideration of PCR genome sequencing for CMV strains that may become resistant to antiviral therapies from long-term antiviral prophylactic exposure. Hematologists or oncologists may help with patients who remain bone marrow-suppressed following transplantation or systemic chemotherapy. Because of related toxicities of the anti-CMV medications and immunosuppressive medications (eg, bone marrow suppression and cytopenias), infectious disease consultation can help in the treatment and monitoring of side effects.

Abstract
Human cytomegalovirus (HCMV) resides in a latent form in hematopoietic progenitors and undifferentiated cells within the myeloid lineage. Maturation and differentiation along the myeloid lineage triggers lytic replication. Here, we used peripheral blood monocytes and the monocytic cell line THP-1 to investigate the effects of 1,25-dihydroxyvitamin D3 on HCMV replication. Interestingly, 1,25-dihydroxyvitamin D3 induces lytic replication marked by upregulation of HCMV gene expression and production of infectious virus. Moreover, we demonstrate that the effects of 1,25-dihydroxyvitamin D3 correlate with maturation/differentiation of the monocytes and not by directly stimulating the MIEP. These results are somewhat surprising as 1,25-dihydroxyvitamin D3 typically boosts immunity to bacteria and viruses rather than driving the infectious life cycle as it does for HCMV. Defining the signaling pathways kindled by 1,25-dihydroxyvitamin D3 will lead to a better understanding of the underlying molecular mechanisms that determine the fate of HCMV once it infects cells in the myeloid lineage.

A role for 3-O-sulfated heparan sulfate in promoting human cytomegalovirus infection in human iris cells. J Virol 2015; 89:5185-92. [PMID: 25717110 DOI: 10.1128/jvi.00109-15] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Accepted: 02/18/2015] [Indexed: 01/17/2023] Open
Abstract
Human cytomegalovirus (HCMV) has emerged as a clinically opportunistic pathogen that targets multiple types of ocular cells and tissues, including the iris region of the uveal tract during anterior uveitis. In this report, we used primary cultures of human iris stroma (HIS) cells derived from human eye donors to investigate HCMV entry. The following lines of evidence suggested the role of 3-O-sulfated heparan sulfate (3-OS HS) during HCMV-mediated entry and cell-to-cell fusion in HIS cells. First, 3-O-sulfotransferase-3 (3-OST-3) expression in HIS cells promoted HCMV internalization, while pretreatment of HIS cells with heparinase enzyme or with anti-3-OS HS (G2) peptide significantly reduced the HCMV-mediated formation of plaques/foci. Second, coculture of the HCMV-infected HIS cells with CHO-K1 cells expressing 3-OS HS significantly enhanced cell fusion. Finally, a similar trend of enhanced fusion was observed with cells expressing HCMV glycoproteins (gB, gO, and gH-gL) cocultured with 3-OS HS cells. Taken together, these results highlight the role of 3-OS HS during HCMV plaque formation and cell-to-cell fusion and identify a novel target for future therapeutic interventions.
