Fundus findings in patients admitted with post COVID-19 sepsis in an intensive care unit.

Purpose: COVID-19 infection is being increasingly identified as a risk factor for the development of ocular infections, especially endogenous endophthalmitis. Current studies primarily report cases among survivors, and the overall prevalence, especially amongst patients admitted with active sepsis is unknown. We report on the fundus and systemic findings of inpatients who were being treated for post-COVID-19 systemic secondary infections in a tertiary intensive care unit. Methods: Retrospective observational study based on chart review. Results: A total of 24 patients were identified. These included 21 (87.5%) males and 3 (12.5%) females with ages ranging from 33 to 72 years (mean 54.1 years). Pre-existing risk factors included type 2 diabetes mellitus, systemic hypertension, chronic kidney disease, multiple myeloma, and patients on long-term corticosteroid/immunosuppressive treatment. Nine patients (37.5%) died and 15 (62.5%) survived. Of a total of 48 eyes, observed fundus lesions included endogenous endophthalmitis (4 eyes of 2 patients, 8.3%), preretinal hemorrhages (4 eyes of 2 patients, 8.3%), optic disc pallor (2 eyes of 1 patient, 4.1%), moderate non-proliferative diabetic retinopathy (4 eyes of 2 patients, 8.3%), Roth spots (2 eyes of 1 patient, 4.1%), and 2 eyes of 1 patient (4.1%) with evidence of previous pan-retinal photocoagulation. Conclusion: Two patients had evidence of endogenous endophthalmitis. These findings suggest that the actual incidence of ocular lesions, especially infections is higher than that reported. Fundus examination should form a part of the management protocol for patients being treated for post-COVID-19 systemic infections.

Indian consensus on the management of CRE infection in critically ill patients (ICONIC) - India.

Background: The increasing burden of carbapenem-resistant Enterobacteriaceae (CRE) carriage and infection in different patient settings in India has created an acute need for guidance for clinicians regarding optimal strategies for the management of CRE infection in critically ill patients. Research design and methods: A multidisciplinary panel of 11 Indian experts in CRE infection assembled for comprehensive discussion and consensus development. The experts developed clinical statements through a systematic review of key literature. Main outcome measures: The panel voted anonymously on 60 clinically relevant questions, through a modified Delphi process. Results: Forty-six key clinical consensus statements (CCS) were proposed. The panel reached a consensus on several important issues, providing recommendations on surveillance, diagnosis, prevention, pharmacokinetic challenges, combination therapy, and cornerstone molecules in CRE infections. The panel also proposed a treatment algorithm for NDM-prevalent settings. Conclusion: These consensus statements may offer clinicians expert guidance on the management of CRE infections. There is a dearth of high-/moderate-level evidence on managing CRE infections; the recommendations presented herein are based on expert opinion.

Fluorine-18 fluorodeoxyglucose positron emission tomography in the evaluation of a patient with presumed ocular tuberculosis.

PURPOSE: To report a case of presumed ocular tuberculosis where a fluorine-18 fluorodeoxyglucose (FDG) PET/CT scan was used to image the chest. DESIGN: Single case report. METHODS: A 35-year-old female patient with recurrent posterior uveitis was examined and investigated. RESULTS: A complete blood study was normal. A tuberculosis quantiferon gold test was positive (5.25 IU). CT scan studies of the chest were normal. She was advised to undergo a PET/CT scan. Increased uptake of tracer was seen in right paratracheal, precarinal, and bilateral hilar nodes and in the left choroid. CONCLUSIONS: FDG-PET/CT scan may be superior to high-resolution computed tomography in detecting concomitant pulmonary pathology.

Ophthalmoscopic findings in adult patients with severe falciparum malaria.

AIM: To report the systemic and ocular findings of four Indian adult patients with severe Plasmodium falciparum infection. MATERIALS AND METHODS: Case reports. RESULTS: The commonest findings seen were posterior pole hemorrhages that were seen in all patients. These included superficial and subretinal hemorrhages. Some of the eyes with subretinal hemorrhages were associated with a premacular hemorrhage. The findings of retinal whitening and vascular changes were seen in one patient. CONCLUSIONS: A spectrum of ocular lesions was noted, including pre-retinal, subretinal hemorrhages, retinal whitening, and retinal vascular anomalies.

Ocular injuries in survivors of improvised explosive devices (IED) in commuter trains.

BACKGROUND: Ocular injuries are common in survivors of terror incidents that involve the use of explosive materials. These explosives are commonly of a High Explosive type (HE) and may be fashioned into improvised explosive devices (IED) that incorporate additional materials to maximise trauma and injuries. Serial IED explosions have occurred in commuter trains in several cities including London and Madrid but data on ocular injuries is limited. We report the ocular injuries of the survivors of a series of IED explosions in crowded commuter trains. METHODS: 28 patients (56 eyes, 28 male, ages ranging from 22 to 52 years (mean 35.27 years) were screened in the triage area or the Intensive Care Unit (ICU). Testing included bedside visual acuity testing, torchlight examination of the anterior segment and dilated (or if necessary, undilated) fundus examination. Selected patients underwent B-scan examination, magnetic resonance imaging of the brain, orbits and the optic nerves or visual evoked potential assessment. The injuries, investigations and procedures were entered into the patient's case sheet as well as into a standardised format suggested by the Indian eye injury registry (IER). RESULTS: 16 of 28 patients (57.1%) had ocular injuries whereas 12 (42.8%) were found to be normal. Injuries were seen unilaterally in 10 patients and bilaterally in six yielding a total of 22 injured eyes. The common injuries were periorbital haemorrhages (09 eyes, 40%); first or second degree burns to the upper or lower lids (seen in 07 eyes, 31.8 %) and corneal injuries (seen in 08 eyes, 36.3%). Open globe injuries were seen in two eyes of two patients (09%). One patient (4.5%) had a traumatic optic neuropathy. CONCLUSION: Ophthalmologists and traumatologists should be aware of these patterns of ocular injuries. Protocols need to include the screening of large numbers of patients in a short time, diagnostic tests (B scan, visual evoked potential (VEP) etc) and early surgery preferably at the initial triage itself as most of the serious injuries in our studies had been missed or not treated at an initial assessment.

Ocular features of hantavirus infection.

Hantavirus infections are an emerging infectious disease that is beginning to be recognized both worldwide and in India as a cause of hemorrhagic fever that may present as a pulmonary syndrome or as a renal syndrome. Reports of ocular involvement are rare and include transient myopia, low intraocular pressure, conjunctival hemorrhages and changes of intraocular dimensions. Eleven patients (10 males, one female, mean age 37.6 years) were admitted to the intensive care unit for pyrexia of unknown origin or hemorrhagic fever following exposure to flood waters. Five male patients (mean age 31.6 years) were identified as suffering from hantavirus infection. In one patient, dot and blot intraretinal hemorrhages were seen in the macula of one eye and streak hemorrhages of the disc in the other. In the remaining four, no fundus abnormalities were seen. Ophthalmologists should be aware of these features.

Choroidal tubercles in neurotuberculosis: prevalence and significance.

PURPOSE: Neurotuberculosis is a relatively common form of tuberculosis and may be seen in 1-10% of patients of systemic tuberculosis and may present in several forms. Ocular lesions are frequently seen, most commonly optic nerve lesions. Limited data are available for choroidal tubercles. We conducted a prospective study 1) to determine the prevalence of choroidal tubercles in a cohort of patients of neurotuberculosis as well as its relative prevalence in the various morphological manifestations and 2) to study the role of co-existent systemic tuberculous infection. METHODS: IRB-approved prospective cross-sectional observational study. A hospital-based cohort of patients underwent a detailed physical, laboratory and ocular evaluation. RESULTS: A total of 52 (20 male, 32 female) patients were evaluated with tubercles being seen in 23 eyes (18 patients, 34.6%). Twenty four patients (46.12%, 16 female, 8 male) presented with intracranial granulomas and 28 (53.8%, 16 female, 12 male) presented with tuberculous meningitis. Tubercles were seen in 10 eyes of 8 (28.5%) patients with tuberculous meningitis and in 13 eyes of 10 patients (41.6%) with intracranial granulomas. This result is not statistically significant. Twenty seven patients (51.9%) had neurotuberculosis without systemic infection, whereas 25 (48.1%) patients had systemic foci. Tubercles were seen in 18 eyes (13 patients) with systemic foci and in 5 eyes (5 patients) of neurotuberculosis alone. The odds ratio for the presence of systemic tuberculosis when choroidal tubercles are present is 5.6 (95% confidence interval: 1.39-24.49, statistically significant [p = 0.005]). CONCLUSIONS: Tubercles were equally likely to occur in either manifestation of neurotuberculosis, and their presence was related to the presence of systemic focus of tuberculous infection. The presence of choroidal tubercles may serve as a diagnostic marker for the presence of an underlying systemic infection.
