Cytomegalovirus Retinitis in the Modern Era of Solid Organ Transplantation

BackgroundCytomegalovirus retinitis (CMVR) is a well-described complication of CMV disease in immunocompromised hosts. While robust data exists for CMVR in patients with acquired immunodeficiency syndrome (AIDS), the incidence and risk factors for CMVR in solid organ transplant recipients (SOTR) with CMV viremia are less defined. MethodsWe performed a retrospective cohort study of SOTR who had CMV viremia and underwent routine ophthalmologic examination between 1/1/2018 and 3/16/2022. Univariate statistics were performed to evaluate risk factors for development of CMVR. ResultsOverall, 38 patients were included, primarily kidney (78.9%), heart (7.9%), and liver (7.9%) transplant recipients. Five patients (13.2%) developed CMVR during the study period. CMVR was diagnosed an average 281 days after index transplantation, 84 days from the most recent rejection episode, and 69 days from onset of viremia. Only 1 patient (20%) had symptoms at the time of CMVR diagnosis. CMVR was associated with preceding allograft rejection as well as transplanted organ type. ConclusionWhile CMV tissue disease more commonly manifests in other organs, CMVR occurred relatively frequently in this group of high-risk SOTR with CMV viremia. As most of the patients in our study did not have ocular symptoms at the time of diagnosis, routine ophthalmologic screening should be considered in SOTR with CMV viremia.

Organ involvement in newly diagnosed sarcoidosis patients in the Netherlands: The first large European multicentre prospective study

BackgroundClinical presentation and prevalence of organ involvement is highly variable in sarcoidosis and depends on ethnic, genetic and geographical factors. These data are not extensively studied in a Dutch population. AimTo determine the prevalence of organ involvement and the indication for systemic immunosuppressive therapy in newly diagnosed sarcoidosis patients in the Netherlands. MethodsTwo large Dutch teaching hospitals participated in this prospective cohort study. All adult patients with newly diagnosed sarcoidosis were prospectively included and a standardized work-up was performed. Organ involvement was defined using the WASOG instrument. ResultsBetween 2015 and 2020, a total of 330 patients were included, 55% were male, mean age was 46 (SD 14) years. Most of them were white (76%). Pulmonary involvement including thoracic lymph node enlargement was present in 316 patients (96%). Pulmonary parenchymal disease was present in 156 patients (47%). Ten patients (3%) had radiological signs of pulmonary fibrosis. Cutaneous sarcoidosis was present in 74 patients (23%). Routine ophthalmological screening revealed uveitis in 29 patients (12%, n = 256)). Cardiac and neurosarcoidosis were diagnosed in respectively five (2%) and six patients (2%). Renal involvement was observed in 11 (3%) patients. Hypercalcaemia and hypercalciuria were observed in 29 (10%) and 48 (26%, n = 182) patients, respectively. Hepatic involvement was found in 6 patients (2%). In 30% of the patients, systemic immunosuppressive treatment was started at diagnosis. ConclusionsHigh–risk organ involvement in sarcoidosis is uncommon at diagnosis. Indication for systemic immunosuppressive therapy was present in a minority of patients.

Ocular Effects of MEK Inhibitor Therapy: Literature Review, Clinical Presentation, and Best Practices for Mitigation.

MEK signaling pathway targeting has emerged as a valuable addition to the options available for the treatment of advanced cancers including melanoma and non-small cell lung cancer. Ophthalmologic monitoring of patients taking part in clinical trials of MEK inhibitors has shown that while ocular effects are common, generally emerging during the first days to weeks of treatment, the majority are either asymptomatic or have minimal visual impact and are benign, resolving without intervention or the need to reduce or stop MEK inhibitor therapy. However rare cases of serious, potentially vision-threatening ocular toxicities have been reported during MEK inhibitor therapy. There is currently no recommendation for routine ophthalmologic screening or monitoring of patients with advanced cancer who are initiating MEK inhibitor therapy. However, baseline ophthalmologic examination may be useful for all patients initiating MEK inhibitor therapy to allow the differentiation of preexisting pathology versus the development of MEK inhibitor-associated retinopathy in the event of the emergence of symptomatic ocular events. Regular ophthalmologic examination may be appropriate for patients at increased risk for ocular events, such as patients with a history of ocular inflammation, infection, or underlying macular/retinal disease. All patients reporting visual disturbance should be referred for prompt ophthalmologic review to determine the potential seriousness of any underlying abnormalities and whether there is a need for treatment modification or specific intervention. Understanding the potential consequences of ocular toxicities is of particular importance in the context of decision-making for the continuation of potentially life-prolonging medications such as MEK inhibitors.

An Eye for A Foot: Alarming Unawareness of Diabetic Retinopathy Among Diabetic Foot Patients.

This study aims to determine the awareness of diabetic retinopathy in patients hospitalized for diabetic foot ulcers, examine their clinical and demographic characteristics, and evaluate their treatment needs. In this prospective study, 62 consequent patients with diabetic foot ulcers who were hospitalized for further treatment in Diabetic Foot Department between June and August 2023 were subjected to ophthalmological examinations. Detailed anterior and posterior segment examinations were performed. Clinical and demographic characteristics and HbA1c levels were recorded. Thirty-nine patients (62.9%) were male and 23 (37.1%) were female. The mean age was 61 ± 11.4 years. The patients had diabetes mellitus (DM) for an average of 19.2 ± 9.6 years. The average HbA1c value of the patients was 9 ± 2.3%. Minor amputation was performed in 35 of 62 patients (56.5%) during treatment. Thirty-one patients (50%) were unaware of the risk of diabetic retinopathy. Of those "unaware" 31 patients, 26 (83.9%) had diabetic retinopathy. Diabetic retinopathy was detected in 57 patients (91.9%) and 3-month interval ophthalmological follow-up screening was recommended for 77 eyes. Eighty percent of the patients never had ophthalmological examination. Intravitreal (IV) injection was performed in 44 eyes, panretinal photocoagulation (PRP) in 2 eyes, and intravenous injection + PRP + vitreoretinal surgery in one eye. Diabetic foot ulcers and diabetic retinopathy are often accompanied by each other. Patients should be informed about this and strongly encouraged to undergo routine ophthalmological examinations, especially when they have advanced diabetic foot disease. Diabetic foot surgeons should keep in mind that a poor eye cannot detect diabetic foot problems.

Dermatologists' and Rheumatologists' Adherence to the Latest Recommendations for Screening of Hydroxychloroquine Retinopathy in Saudi Arabia: A Cross-Sectional Study.

Hydroxychloroquine (HCQ) is used to manage the symptoms of inflammatory rheumatic and dermatologic disorders. However, HCQ retinopathy is aserious side effect becauseeven after the drug is discontinued, irreversible vision loss may occur and may continue to progress.According to the American Academy of Ophthalmology (AAO),the recent recommendation for HCQ dosing is ≤5 mg/kg of real body weight, with baseline ophthalmologic screening during the first year of HCQ treatment and yearly screening after five years of continuous use of HCQ medication, unless the patient is at high risk or symptoms have developed.Nonetheless, this study aims to assess dermatologists' and rheumatologists' adherence in Saudi Arabia to the 2016 AAO HCQ retinal toxicity guidelines. A questionnaire-based cross-sectional study was conducted on dermatologists and rheumatologists in Saudi Arabia. It was conducted between August and September 2022 and questionnaires were sent to dermatologists and rheumatologists via their professional emails or accounts. The collected sample consisted of 635 participants; males and females represented 54% and 46%, respectively; 47.6% were consultants; 50.1% were rheumatologists; and 49.9% were dermatologists. Approximately 28.2% of the participants reported treating one to three patients with HCQ in the previous year. Only 45.4% of the respondents stated that the ideal recommended HCQ dose for reducing the risk of retinopathy is "≤ 5 mg/kg of the real body weight." More than 50% of the respondents stated that systemic lupus erythematosus was the most common disease for which they used HCQ. Additionally, 36.5% of the physicians screened patients during the first year of HCQ treatment. We found significant associations between practice levels and specialty practice-related questions with a p-value of less than 0.05, except for the specialty practice-related question, "What is the most common disease for which you use HCQ?" with a p-value of 0.074. Also, we found significant associations between all demographic variables and screening-related variables with a p-value of less than 0.05, with two exceptions: no significant associations were found between specialty area and the screening-related question, "Do you recommend screening tests for all patients starting treatment with HCQ?" at p = 0.270, and gender and the screening-related question, "When would you recommend screening tests for a patient without risk?" at p = 0.142. Dermatologists and rheumatologists in Saudi Arabia have shown poor adherence to the most recent AAO recommendations. Educating physicians and patients about the AAO guidelines is needed for HCQ to be used in a way that is both effective and safe.

T1D and T2D predispose to higher Nd:YAG capsulotomy rates following cataract surgery: analysis of 53,471 consecutive cases

PurposeTo assess the effect of diabetes type on Nd:YAG capsulotomy rates following cataract surgery. DesignA retrospective cohort study. MethodsAll patients who underwent cataract extraction at the Department of Ophthalmology, Bristol Eye Hospital, Bristol, UK, between 2003 and 2017 were included. The Nd:YAG capsulotomy rate following cataract surgery was assessed and compared between nondiabetic, type 1 diabetes (T1D), and type 2 diabetes (T2D) patients. Multivariate Cox regression analysis controlling for age and sex was used to estimate hazard ratios for Nd:YAG laser capsulotomies. ResultsIncluded were 53,471 consecutive cataract surgeries. Overall, 42,651 eyes (79.8%) were in nondiabetic patients, 823 eyes (1.5%) were in T1D patients, and 9,997 eyes (18.7%) were in T2D patients. The mean follow-up time was 6.8 ± 4.2 years. In univariate analysis, the eyes of T1D patients (p < 0.001) and T2D patients (p = 0.003) had significantly higher Nd:YAG laser capsulotomy rates than the eyes of nondiabetic patients. In Cox regression analysis adjusted for the patient's age and sex, DM1 (HR 1.692, 95%CI 1.390-2.059, P<0.001) and DM2 (HR 1.157, 95%CI 1.075-1.244, P<0.001) remained significantly predictive for higher Nd:YAG laser capsulotomy rates. ConclusionIn our large cohort study, patients with T1D and T2D were predisposed to high risk for Nd:YAG capsulotomy following cataract surgery. This study may be beneficial and raise awareness regarding the assessment of posterior capsular opacification development in pseudophakic diabetic patients, particularly those with T1D. The significance of ophthalmology screening for diabetes individuals is further supported by this issue.

ZEISS PLEX Elite 9000 Widefield Optical Coherence Tomography Angiography as Screening Method for Early Detection of Retinal Hemangioblastomas in von Hippel-Lindau Disease.

To evaluate early detection of retinal hemangioblastomas (RHs) in von Hippel-Lindau disease (VHLD) with widefield optical coherence tomography angiography (wOCTA) compared to the standard of care in ophthalmologic VHLD screening in a routine clinical setting. We conducted prospective comparisons of three screening methods: wOCTA, standard ophthalmoscopy, and fluorescein angiography (FA), which was performed only in uncertain cases. The numbers of detected RHs were compared among the three screening methods. The underlying causes for the lack of detection were investigated. In 91 eyes (48 patients), 67 RHs were observed (mean, 0.74 ± 1.59 RH per eye). FA was performed in eight eyes. Ophthalmoscopy overlooked 25 of the 35 RHs detected by wOCTA (71.4%) due to the background color of the choroid (n = 5), small tumor size (n = 13), masking by a bright fundus reflex (n = 2), and masking by surrounding retinal scars (n = 5). However, wOCTA missed 29 RHs due to peripheral location (43.3%). The overall detection rates were up to 37% on the basis of ophthalmoscopy alone, up to 52% for wOCTA, and 89% for FA. Within the retinal area covered by wOCTA, the detection rates were up to 46.7% for ophthalmoscopy alone, up to 92.1% for wOCTA, and 73.3% for FA. The overall low detection rate of RHs using wOCTA is almost exclusively caused by its inability to visualize the entire peripheral retina. Therefore, in unclear cases, FA is necessary after ophthalmoscopy. Within the imageable retinal area, wOCTA shows a high detection rate of RHs and therefore may be suitable to improve screening for RHs in VHLD.

Comparative Analysis of Retinal Structural and Angiographic Parameters in Diabetic Patients, Alzheimer's Disease Patients, and Healthy Controls: An OCT-Based Study.

Objective: This study aimed to investigate the potential connections between Alzheimer's Disease (AD) and diabetes. Methods: This is a cross-sectional study in which AD and diabetes patients sent by the Psychiatry and Diabetes Departments for ophthalmological screening were observed for inclusion/exclusion criteria. Patients were divided into two comparison groups. The first group (n=3) consisted of the age-matched normal and diabetic patient of the stage 3 AD disease participant. The second group (n=3) was for the stage 5 AD patient with diabetes and normal age-matched controls. Each patient underwent a full ophthalmological examination and SS-OCT (Swept Source-Ocular Computer Tomography) for retinal evaluation. Results: A total of 6 patients (12 eyes) were obtained, three men and three women. In the early AD group, the patient with diabetes showed lower macular thickness compared to other groups. In the nasal-inferior (NI) and temporal-superior (TS) ganglion cell layer (GCL), the AD patient showed statistically significant lower values compared to the other patients. In the moderately severe AD group, we found that the AD patient had lower retinal nerve fiber layer (RNFL) thickness on the temporal side compared to the rest of the patients and both the AD patient and diabetes patient showed lower RNFL thickness in the nasal-superior (NS) quadrant. Also, the foveal avascular zone (FAZ) area was statistically significantly lower for both the diabetes and AD patients compared to the healthy control. Conclusions: In conclusion, distinct retinal findings associated with AD and diabetes in young and elderly patients were revealed in our study. The clinical implications and potential interplay between these conditions need to be elucidated by further research. Abbreviations: AD = Alzheimer's Disease, SS-OCT = Swept Source - Ocular Computer Tomography, GCL = Ganglion cell layer, RNFL = Retinal nerve fiber layer, FAZ = foveal avascular zone.

Diagnosis of Congenital Toxoplasmosis: Challenges and Management Outcomes.

Introduction Congenital toxoplasmosis (CT), despite being mostly subclinical at birth, can cause disabling disease in the fetus and lead to long-term sequelae. It is an important cause of chorioretinitis in infants and adolescents. Data on postnatal treatment are controversial, and there is a lack of universal guidelines. Methods A cross-sectional study of newborns with suspected CT was conducted between January 2007 and December 2021. Results Seventy-one patients with suspected CT were included. During pregnancy, 64 (90.1%) of the mothers underwent therapy, of which59 (83.1%) with spiramycin. Amniocentesis identified one positive polymerase chain reaction assay. Most newborns were asymptomatic with normal laboratory, ophthalmological, and hearing screening. There was one case of hyperproteinorrachia. Fifty-seven patients (80.3%) started treatment: 42 (73.7%) with spiramycin, seven (12.3%) with pyrimethamine, sulfadiazine, and folinic acid (P+S+FA), and eight (14%) with P+S+FA intercalated with spiramycin. Adverse effects were found in 11 (19.3%) cases, mainly neutropenia.After investigation, we found three confirmed CT cases corresponding to 4.2% of suspected cases and an incidence of 0.4 per 10,000 births. All had normal clinical and laboratory exams in the neonatal period and started P+S+FA, fulfilling 12 months of therapy. During the follow-up, all presented normal psychomotor development without any long-term sequelae. Conclusion The lower incidence in our study, compared to the incidence in Europe, may be related to the decline in the prevalence of toxoplasmosis as well as the effectiveness of measures to prevent primary infection and a well-established program of antenatal screening, followed by the early initiation of treatment during pregnancy to prevent vertical transmission.

Impact of COVID-19 restrictions on diabetes mellitus management in Qatari primary care settings

IntroductionIn 2019, Coronavirus Diseases 2019 (COVID-19) emerged as a pandemic making diabetic patients among the most vulnerable to this virus. Previous studies showed contradicting evidence for the impact of “lockdown” on the management of diabetic patients. New models of service delivery were introduced in Primary Health Care Corporation (PHCC) (Qatar’s largest primary care provider) to ameliorate the risk of infection to both patients and health care workers including converting face to face chronic disease appointments (NCD, antenatal, and preventive visits) to telephone and video consultations. This study aimed to compare access and outcomes of PHCC registered diabetics pre-COVID and during the COVID-19 lockdown period.MethodsThe study was conducted as a 3 year historic cohort using PHCC’s electronic health record system. Individuals with an established diagnosis of diabetes mellitus (DM) before January 2019 and having at least one clinical encounter per year in a PHCC health center during the study period starting Jan 2019 to Dec 2021 were recruited. Pre-COVID-19 period was defined as the interval between January 2019 and February 2020, while the COVID-19 lockdown period was defined as the interval between February 2020 to December 2021. The study used a paired observation approach on selected process indicators on delivery of health services in line with PHCC’s diabetes management guidelines (at least two HbA1C tests done per year and at least one each of the following per year—low-density lipids (LDL) test, ophthalmology screening, podiatry assessment, health education and dietetics clinic consultations) and outcome indicators (blood pressure readings and the results of two laboratory tests: blood HbA1c and serum LDL level).ResultsCOVID-19 was associated with an overall mean reduction of 0.9 per year of consultations. Similarly, the delivery of annual assessments as per guidelines were also impacted. Of these, the probability of achieving the designed target for two HbA1C tests per year was reduced by almost a half (paired OR=0.47) during COVID-19 compared to pre- COVID-19 period. Conversely, a significant increase in the probability of having at least one each of LDL test, ophthalmology screening and dietetics consultation was observed (paired OR=1.84, 1.62 and 1.94 respectively) during COVID-19. The probability of having inadequate glycemic control (HbA1C > =7%) was significantly increased by 32% during COVID-19 period. Likewise, the probability of experiencing inadequately controlled blood pressure was significantly increased by 47% during the pandemic. Conversely, the probability of having Inadequately controlled blood lipids (LDL 2.6 mmol/L+) was significantly reduced by 9%.ConclusionsThe impact of the COVID-19 pandemic on the primary health care services in Qatar has highlighted PHCC’s resilience by the introduction of virtual consultations during COVID-19 restrictions. Only one process indicator was significantly impacted during COVID-19 restrictions, namely having at least two HbA1C tests per individual with diabetes per year. However, the control of the disease according to HbA1c and blood pressure measurements showed a noticeable deterioration during COVID-19.

Artificial intelligence enhanced ophthalmological screening in children: insights from a cohort study in Lubelskie Voivodeship

This study aims to investigate the prevalence of visual impairments, such as myopia, hyperopia, and astigmatism, among school-age children (7–9 years) in Lubelskie Voivodeship (Republic of Poland) and apply artificial intelligence (AI) in the detection of severe ocular diseases. A total of 1049 participants (1.7% of the total child population in the region) were examined through a combination of standardized visual acuity tests, autorefraction, and assessment of fundus images by a convolutional neural network (CNN) model. The results from this artificial intelligence (AI) model were juxtaposed with assessments conducted by two experienced ophthalmologists to gauge the model's accuracy. The results demonstrated myopia, hyperopia, and astigmatism prevalences of 3.7%, 16.9%, and 7.8%, respectively, with myopia showing a significant age-related increase and hyperopia decreasing with age. The AI model performance was evaluated using the Dice coefficient, reaching 93.3%, indicating that the CNN model was highly accurate. The study underscores the utility of AI in the early detection and diagnosis of severe ocular diseases, providing a foundation for future research to improve paediatric ophthalmic screening and treatment outcomes.

Comprehensive Analysis of Diabetes Mellitus-Associated Visual Impairment: Insights from Ophthalmological Screening Program in Libya

Clinical manifestations and associated factors of uveitis in patients with pulmonary sarcoidosis: a case control study

Sarcoidosis, an idiopathic and inflammatory disease, affects various organs and can manifest as uveitis. Due to limited evidence, researchers investigated the risk factors associated with uveitis in patients with pulmonary sarcoidosis. A retrospective study was conducted on 71 pulmonary sarcoidosis patients, including 19 with uveitis and 52 without. Data on involved organs, imaging findings, spirometry, and analyses from blood and bronchoalveolar lavage fluid were collected. Logistic regression models were used for multivariate analysis. Among the 71 newly diagnosed pulmonary sarcoidosis patients, uveitis was observed in 19 patients (26.8%). No significant differences were found in clinical characteristics between patients with and without uveitis. Fewer patients with uveitis presented lung parenchymal lesions (P = 0.043). In multivariate analysis, skin lesions (aOR 7.619, 95% CI 1.277–45.472, P = 0.026) and ophthalmic symptoms (aOR 4.065, 95% CI 1.192–13.863, P = 0.025) were associated with uveitis. Absence of uveitis was related to lung parenchymal lesions (aOR 0.233, 95% CI 0.062–0.883, P = 0.032). Approximately one-quarter of patients with an initial diagnosis of pulmonary sarcoidosis were diagnosed with uveitis. Presence of skin lesions, ophthalmic symptoms, and absence of lung parenchymal lesions were related to uveitis. These results need to be clarified by further studies to confirm the clinical role of early ophthalmologic screening for pulmonary sarcoidosis patients with these factors.

Risk Factors and Outcomes of Delayed Presentation of Diabetic Retinopathy Patients to a County Hospital.

To identify risk factors and evaluate outcomes of patients with delayed presentation and advanced diabetic retinopathy in our safety-net county hospital population. A retrospective study was performed on 562 patients who presented with a new diagnosis of diabetic retinopathy (DR). Delayed presentation was defined as moderate or severe nonproliferative diabetic retinopathy (NPDR) or proliferative diabetic retinopathy (PDR) at the initial visit. Comparisons between patient groups were performed with chi-square or Fisher's exact test for categorical variables and multinomial logistic regression for multivariable analysis. Linear and logistic regression modeling with general estimating equations to account for patients having two eyes was used to compare eye-level outcomes. Lack of a primary care provider (PCP) was highest in patients who presented initially with PDR (28.8%), compared to 14.3% in moderate/severe NPDR, 12.4% in mild NPDR, and 7.6% in no DR groups (P < 0.001). Only 69.4% of patients with a PCP had an ophthalmology screening referral. Highest lack of referral (47.2%) was seen in the PDR group (P = 0.002). Patients with PDR were more likely to be uninsured (19.2%) compared to no and mild DR groups, with rates of 7.6% and 9.0%, respectively (P = 0.001). The PDR group had worse initial and final visual acuities (P < 0.001). Several risk factors were noted for delayed DR presentation, including lack of PCP, lack of screening referral, and uninsured/underinsured status. Patients with advanced DR at presentation had worse final visual outcomes despite aggressive treatment. Screening programs targeting populations with identified risk factors are essential for improving outcomes.

Associations between fatty acid intake and diabetic retinopathy in a Japanese population

Residents of Chikusei City, aged 40–74 years, underwent systemic and ophthalmological screening, and participants with diabetes were included in this analysis. Dietary intake was assessed using a food frequency questionnaire and calculated as a percentage of the total energy. The presence of diabetic retinopathy (DR) was defined as Early Treatment Diabetic Retinopathy Study levels ≥ 20 in either eye. The association between dietary fatty acid intake and DR has been examined in a cross-sectional study. Among the 647 diabetic participants, 100 had DR. The mean total fat and saturated fatty acid (SFA) intakes were 22.0% and 7.3% of the total energy intake, respectively. After adjusting for potential confounders, the highest quartiles of total fat and SFA intake were positively associated with the presence of DR compared with the lowest quartiles (odds ratios (95% confidence intervals), 2.61 (1.07–6.39), p for trend = 0.025, and 2.40 (1.12–5.17), p for trend = 0.013, respectively). No significant associations were found between DR prevalence and monounsaturated or unsaturated fatty acid intake. These results suggest that a high intake of fat and SFA may affect the development of DR, even in individuals whose total fat intake is generally much lower than that of Westerners.

Is there room for prompt routine ophthalmic examination in neonates with congenital cytomegalovirus (CMV) infection during the neonatal period?

To establish the clinical necessity of routine targeted ophthalmic examination of newborns with congenital cytomegalovirus (CMV) infection during the neonatal period. This retrospective study included consecutive neonates that were referred for ophthalmological screening within the context of a proven congenital CMV infection. The presence of CMV-related ocular and systemic findings was determined. Among the 91 patients included in this study, 72 (79.12%) were symptomatic with one or more of the following manifestations: abnormal brain ultrasound (42; 46.15%), small for gestational age (29; 31.87%), microcephaly (23; 25.27%), thrombocytopenia (14; 15.38%), sensory neural hearing loss (13; 14.29%), neutropenia (12; 13.19%), anemia (4; 4.4%), skin lesions (4; 4.4%), hepatomegaly (3; 3.3%), splenomegaly (3; 3.3%), direct hyperbilirubinemia (2; 2.2%). Not one single neonate in this cohort had any of the ocular findings surveyed. The presence of ophthalmological findings among neonates with congenital CMV infection during the neonatal period is infrequent, suggesting that routine ophthalmological screening may be safely deferred for the post-neonatal period.

Ocular candidiasis in a tertiary hospital in Japan: A 10-year single-center retrospective study

Ocular candidiasis is a major complication of candidemia that is sometimes sight-threatening. Although prompt ophthalmologic consultation and antifungal medication have been emphasized, recent changes in the causative species and drug susceptibilities make the picture unclear. This study aimed to determine whether there are trends among patients with ocular candidiasis and included 80 patients with candidemia who underwent ophthalmological screening at our hospital between 2010 and 2020. Data on the clinical characteristics, comorbidities, biochemical test results, causative Candida species, treatment, outcomes, visual acuity, and antifungal susceptibility were collected and analyzed. Statistical analyses were performed by comparing two groups, namely, the ocular candidiasis (n = 29) and non-ocular candidiasis (n = 51) groups. In the ocular candidiasis group, there were significantly more cases of central venous catheter insertion (82.8%, p = 0.026) and Candida albicans candidemia (72.4%, p < 0.001). Regarding ocular involvement, the majority of patients were asymptomatic. Most cases improved with antifungal therapy, but one case underwent vitrectomy. Between 2016 and 2020, there was a diversification of species, with a decrease in Candida parapsilosis and the emergence of Candida glabrata and Candida tropicalis. Regarding drug susceptibility, the minimum inhibitory concentrations of echinocandin and 5-fluorocytosine against Candida albicans, Candida parapsilosis, and Candida glabrata were slightly increased. In conclusion, in addition to appropriately performing ophthalmologic examinations, it is beneficial to select antifungal agents according to the diversity of species and drug susceptibilities.

Awareness of diabectic retinopathy among diabetics in urban population of Hyderabad, South India

Diabetes Mellitus (DM) is a significant public health burden in India. Focus on Diabetes and its complications is important to prevent mortality and morbidity due to this disease. Lack of awareness is one of the main barrier for detection of DM and its complications. Diabetic retinopathy (DR) is one of the most common complication of DM which causes of blindness and visual impairment. The purpose of this study was to assess knowledge and attitude of diabetic patients towards eye care and DR in urban south Indian population.Cross-sectional study was done on 537 patients with Type 2 Diabetes Mellitus. All patients underwent complete ocular examination including visual acuity, anterior segment and fundus examination using slit-lamp biomicroscope by attending Ophthalmologist. They were administered questionnaire to test their knowledge and attitude. Their answers were documented. Statistical analysis was done using SPSS software (IBM).Out of 537 patients (50.9%) patients knew that there was relationship between Diabetes and Retinopathy while (49.1%) patients were not aware of. 60.4% of patients were of the opinion that there was no need of regular screening if vision in both eyes are good and 39.6% of patients were of the opinion that they should undergo a routine ophthalmology screening every year despite of good vision in both the eyes. 69.6% of patients said that good control of DM might prevent DR. The level of knowledge of DR was found to be significantly associated with patients’ educational level (p=0.038). Patients with relatively higher educational level were more aware of DR occurring as a consequence of diabetes. Patients with longer duration of Diabetes had more knowledge on DR (p=0.001).In our study there was an association between educational qualification and knowledge regarding Diabetic retinopathy. (p value=0.04). This stresses on the importance of health education amongst rural and illiterate population.

Viral-specific T cells for Cytomegalovirus retinitis following hematopoietic stem cell transplantation: A success story.

Cytomegalovirus retinitis (CMVR) following hematopoietic stem cell transplantation (HCT) for a primary immunodeficiency is a rare but highly morbid condition with potential irreversible consequences despite optimal antiviral pharmacotherapy. Viral-specific T cells (VSTs) pose a promising and safe approach eradicating intractable viral disease. We describe the case of a 21-month-old male with Wiskott-Aldrich syndrome (WAS) and CMVR post HCT with sustained long-term virologic and clinical response after CMV-specific T-cell therapy. This case highlights the need to consider VST as an adjunct upfront strategy in refractory CMVR and for routine ophthalmologic screening and surveillance in high-risk patients post HCT.
