Ophthalmic Manifestations of Leukemia and Their Management

Patients with leukemia often have ophthalmic manifestations. These occur either from direct infiltrations of neoplastic cells or from indirect or secondary causes. Nearly all ocular structures can be affected by leukemia. Sometimes, ophthalmic involvement can be the first sign of disease relapse. This review article aims to highlight different ocular manifestations of leukemia along with treatment. It involves studying the available material in textbooks, printed and online journals. As there is high prevalence of ocular findings in leukemia, it can be a standard practice that all leukemic patients should have screening by ocular examination. Awareness of the clinical spectrum of leukemic infiltration of ocular region is essential for rapid diagnosis, prompt initiation of treatment and better outcome. If prompt diagnosis and treatment can be done, worsening of vision may be minimized or prevented. Mugda Med Coll J. 2024; 7(1): 36-41

EXPLORING THE CLINICAL SPECTRUM AND INDIVIDUALIZED DRUG THERAPY IN PEMPHIGUS VULGAR IS: A CASE SERIES

Pemphigus Vulgaris (PV) is a rare, chronic, life-threatening immunopathogenic disease that is characterized by flaccid, easily ruptured intraepithelial bullae, mostly found on the skin and mucous membranes. Attempting to keep the treatment plan of this potentially deadly disorder in primary focus, we have observed five patients with Pemphigus vulgaris. All patients have been presented with oral lesions or ulcers resulting in difficulty in swallowing. Patient one had a family history of the disease, while the other patients did not present any family history. All five patients had diverse ways of dealing with the disease before getting hospitalized. Microcytic anaemia and hypoalbuminemia have been found in all of them. Patients 1 and 3 had leucocytosis, while patient three had platelets in clumps with Hypercobalaminemia and the presence of ketone bodies in urine analysis. The Desmoglein I and Desmoglein III Antibody along with Punch biopsy results, confirmed the diagnosis. All patients were given systemic corticosteroids on hospitalization, but the case series observed variations in the dosages emphasizing individualized drug therapy. Some developed psychological impairment, some had generalized headaches or cardiac impairment, while ophthalmic involvement was seen in the other patients. Healthcare providers should do close monitoring while providing individualized drug therapy to prevent any systemic involvement and further complications.

Disorders with Ophthalmic and Thoracic Involvement.

A variety of systemic conditions involve the thorax and the eyes. While subtle or nonspecific eye symptoms can be the initial clinical manifestation of some disorders, there can be additional manifestations in the thorax that lead to a specific diagnosis and affect patient outcomes. For instance, the initial clinical manifestation of Sjögren syndrome is dry eye or xerophthalmia; however, the presence of Sjögren lung disease represents a fourfold increase in mortality. Likewise, patients with acute sarcoidosis can initially present with pain and redness of the eye from uveitis in addition to fever and parotitis. Nearly 90% of patients with sarcoidosis have thoracic involvement, and the ophthalmologic symptoms can precede the thoracic symptoms by several years in some cases. Furthermore, a diagnosis made in one system can result in the screening of other organs as well as prompt genetic evaluation and examination of family members, such as in the setting of Marfan syndrome or Ehlers-Danlos syndrome. Multimodality imaging, particularly CT and MRI, plays a vital role in identification and characterization of these conditions. While it is helpful for ophthalmologists to be knowledgeable about these conditions and their associations so that they can order the pertinent radiologic studies, it is also important for radiologists to use the clues from ophthalmologic examination in addition to imaging findings to suggest a specific diagnosis. Systemic conditions with thoracic and ophthalmologic manifestations can be categorized as infectious, inflammatory, autoimmune, neoplastic, or hereditary in origin. The authors describe a spectrum of these conditions based on their underlying cause. ©RSNA, 2024.

Eosinophilic Granulomatosis with Polyangiitis with ophthalmic involvement: A Case report and Literature Review

Eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg-Strauss syndrome, is a systemic necrotizing vasculitis primarily affecting small blood vessels. It is characterized by extravascular eosinophilic granulomas, peripheral eosinophilia, and often coexists with asthma. This rare condition can affect individuals of any gender and age, presenting with a variety of multisystemic symptoms. Prognosis is largely influenced by cardiac involvement, evaluated using the Five-Factor Score (FFS) to guide treatment decisions. Respiratory manifestations, particularly severe and corticosteroid-dependent asthma, are common in EGPA and may aid in its early diagnosis. In this case report, we describe a patient with an uncontrolled asthma admitted for moderate asthma exacerbation. Clinical examination revealed ocular redness and skin lesions, along with hypereosinophilia on assessment and reticulo-micronodular infiltrates on chest CT scan. EGPA diagnosis was confirmed based on the ACR 1990 criteria, wich have been updated and substituted with more objective criteria in 2022. According to the FFS score, the patient underwent systemic corticosteroid therapy in conjunction with azathioprine, leading to an overall favorable outcome over a 3-year follow-up period.

The Effectiveness of Facial Exercise Therapy in Ophthalmic Complications of Facial Nerve Palsy and the CADS Grading Scale as an Ophthalmic-Specific Grading System.

The effectiveness of facial exercise therapy in facial nerve palsy is well documented in the literature. However, there is no study examining its effect on ophthalmic manifestations of facial nerve palsy. The study reports its impact on the ophthalmic manifestations of facial nerve palsy using the ophthalmic-specific CADS grading system. A retrospective case series of patients aged 18 years or older with facial nerve palsy was performed in a single specialist center between 2013 and 2019. Inclusion criteria were ophthalmic involvement, recorded CADS, and Sunnybrook grading scale pre- and post-treatment. A total of 73 patients were identified. There were 24 patients (M = 11, F = 13) who received facial exercise therapy only (group 1) and 49 patients (M = 17, F = 32) who received combined treatment of facial exercise therapy and eyelid surgery (group 2). The mean ages were 54.8 and 49.7 years, respectively. The groups were further subdivided into early (<3 months), intermediate (3-12 months), and late presenters (>12 months). In group 1, statistically significant improvements were seen in early (static asymmetry and dynamic function), intermediate (cornea), and late groups (cornea, static asymmetry, and dynamic function). The Sunnybrook grading scale was unable to detect changes in the ophthalmic features post-therapy or to report the corneal status. Facial exercise therapy is likely to improve ophthalmic manifestations of facial nerve palsy, in particular, those with static asymmetry and dynamic function of eye closure. The CADS grading scale is more suitable for the ophthalmic assessment.

“Not much room for mushrooms” in the heart: knowns and unknowns of fungal infective endocarditis

Fungal infective endocarditis is a rare but highly lethal condition. Its diagnosis is often delayed due to nonspecific symptoms, inconclusive medical imaging, and negative blood cultures. Recent reviews of cases and series over the last 5 years indicate that the condition remains rare and lethal. If fungi are identified as the causative agents in more than 5% of patient cases with infective endocarditis, it is likely that risk factors such as immune suppression or cardiac implants are probably involved. A series derived from recent case reports indicates that Candida and Aspergillus are still the main causative infectious agents, with. C parapsilosis on the rise. From these cases, diagnostic clues (frequent embolisms, ophthalmic involvement, large, mobile and friable vegetation, non-valvular cardiac manifestations) are pointing towards fungal IE. These reports, however, are not standardized and a publication bias towards rare microorganisms or towards a favorable outcome might exist. Complications might be underreported, and important data such as diagnostic delay are absent or difficult to retrieve. Pharmacologic treatment is not fully standardized. Knowledge of resistant strains in this respect is important. Statistical analysis for the effect of complications and treatment modalities on outcome shows that any result should be treated cautiously. The current series is by no means a valid substitute for a well-designed series of fungal endocarditis. However, the better outcome with Candida and patients treated with surgery confirm earlier results. An international multicentric standardized registry of cases with fungal endocarditis in order to improve the outcome of this disease is highly needed. The effect of diagnostic delay on outcome remains elusive and should be resolved.

Simplified practice for ophthalmologist consultation in malar fractures: A retrospective study

Zygomatic bone contributes to the orbital walls, and therefore associated injuries carry a high risk of severe dysfunction of the visual apparatus. The aim of our study was to retrospectively assess the spectrum and frequency of ophthalmic involvement in patients presenting with malar fracture, and the need for referral to an ophthalmologist for evaluation.In total, 102 patients presenting with malar fracture between January 2008 and August 2017 at Bapuji Dental College and Hospital, Davangere, Karnataka were enrolled in this study. Patients with confirmed malar fracture were categorized according to Henderson's classification, and associated ocular injuries were recorded. Assessment of the spectrum and frequency of ophthalmic involvement in patients presenting with different types of malar fracture was then carried out, followed by categorization of the need for referral to the ophthalmologist with regard to the associated ocular injury, as per the Al-Qurainy et al. (1991) scoring system, allocating the patients to early, routine, and non-referral categories.Statistically significant differences in proportions of various types of ophthalmic involvement were found between categories of malar fracture, and in degrees of ophthalmic involvement within each category of malar fracture, except in the Type II group of patients. The most severe ocular injuries were noted in Type VII followed by Type V, with the least severe injuries noted in Type II patients. According to the Al-Qurainy et al. (1991) scoring system, eight patients required early referral, 10 patients needed routine referral, and 84 patients were in the non-referral category.Categorization of referral of patients to an ophthalmologist in hospitals lacking ophthalmology departments can be based on the Al-Qurainy et al. classification of referral for Henderson's Type III, IV, and VI. Henderson's Type I and II patients need to be referred only in medicolegal cases. Henderson's Type VII and V patients require mandatory referral.

Overlapping comorbidities of eye and the skin: A review

Abstract The involvement of the eye is known in many mucocutaneous disorders. Some of these diseases may also lead to significant scarring and occasional vision loss. With this brief article, an attempt is made to highlight ophthalmic involvement in certain skin disorders. The workup of these diseases should essentially include eye examination for appropriate clinical outcomes.

Evaluation of Quality of Life and Emotional Disturbances in Patients with Diabetic Retinopathy.

The purpose of this study was to evaluate the association of Diabetic Retinopathy (DR) and diabetic macular edema with vision-related quality of life, as well as the potential association between the disease's severity, emotional status of patients and the manifestation of anxiety and psychological features. Patients with fundoscopic findings had significantly lower scores in all VFQ-25 subscales, indicating worse quality of life in comparison to patients without DR. Severity of DR, greater levels of anxiety, daily sitting time, unemployment and lower education level, were all found to be significantly, negatively associated with a worse quality of life. Regarding emotional status, more years of suffering from diabetes, treatment with insulin and the hours being idle per day were associated with an increased burden of anxiety. In addition, the presence of a concomitant disease, findings in fundoscopy, diabetic macular edema and treatment with anti-VEFG injections, as well as the number of doses, were significantly associated with greater anxiety. Multivariate analysis showed that having Severe Non-Proliferative Diabetic Retinopathy or having Proliferative Diabetic Retinopathy and receiving insulin therapy (alone or in combination with another treatment), were significantly associated with higher levels of anxiety. The well-established impact of DR on the patients' well-being, quality of life and emotional status render DR and CME prevention, stabilization or delaying progression as a necessity in order to protect patients from developing psychiatric symptoms. On the other hand, the speculated bi-directional association between emotional problems and DR progression highlights the importance of acknowledging and dealing with psychological issues with the aim of delaying DR progression.

Herpes Zoster in Hospitalized Patients With Inflammatory Bowel Disease: National Analysis of Disease Presentation and Age Distribution.

Studies have demonstrated an increased risk of herpes zoster (HZ) in patients with inflammatory bowel disease (IBD). Most recently, the Advisory Committee on Immunization Practices recommended HZ vaccination for adults aged 19 years and older who are at increased risk of shingles due to their disease or drug-related immunosuppression. We aimed to assess the burden of HZ in IBD inpatients and contribute with scientific evidence for an appropriate age cut-off vaccination recommendation. Population-based cross-sectional analysis using the 2014 US National Inpatient Sample (NIS). We measured the frequencies and demographics of adult patients with IBD admitted to the hospital with an HZ diagnosis. Age-stratification analysis was performed, and age groups were compared with non-IBD inpatients with an HZ diagnosis. From 307,260 IBD discharges, 1110 (0.35%) patients were found to have HZ as follows: shingles 63%; post-herpetic neuralgia 26%; HZ with ophthalmic involvement 7%; HZ with neurological involvement 4%. Women with IBD were more likely to have shingles ( P =0.002) and post-herpetic neuralgia ( P =0.001) than men with IBD. The shingles distribution by age in IBD inpatients was 18 to 39 (13%), 40 to 49 (19%), 50 to 59 (18%), 60 to 99 (50%) compared with 18 to 39 (8%), 40 to 49 (6%), 50 to 59 years (14%), 60 to 99 (72%) in non-IBD inpatients ( P =0.0004). Hospitalized patients with IBD were found to have a higher frequency of shingles at younger ages when compared with hospitalized patients without IBD. Shingles is more frequent in women, and their prevalence steadily increases with aging though 32% of cases were seen in patients younger than age 50.

COVID-19-Associated Rhino-Orbital Mucormycosis in a Tertiary Health Care Center in Odisha, India.

Background Mucormycosis is an opportunistic infection that mainly affects immunocompromised individuals, including those with uncontrolled diabetes, malignancies, or those who have exposure to high-dose corticosteroids for a long time. Western Odisha, India, witnessed a significant rise in post-COVID-19 rhino-orbital mucormycosis (ROM), which created a need for comprehensive research on post-COVID-19 ROM. Objective This study aimed to investigate the prevalence, clinical characteristics, and outcomes of post-COVID-19 ROM in a tertiary care hospital in Western Odisha, India, with the objective of understanding ROM as a nationally notifiable disease. Subjects and methods A prospective hospital-based study was conducted. Mucormycosis cases were reported within the period, from May 17, 2021, to July 31, 2021, including all post-COVID-19 patients who exhibited clinical manifestations of mucormycosis. Patients with histopathologically negative reports of mucormycosis were excluded. Results Of the 35 included, 25 were diagnosed with ROM. The age group of 46-50 years showed a predominance (n=6), with a mean age of 50.53 years. The male-to-female ratio was 2:1. Specifically, 88% of the patients included had diabetes mellitus, 8% had chronic kidney diseases, 8% had sepsis, and 4% had hypertension. ROM was the predominant manifestation (60%, n=15), with the majority presenting with orbital cellulitis (80%), followed by unilateral orbital apex syndrome (12%), bilateral orbital apex syndrome (4%), ophthalmic vein involvement (4%), and osteomyelitis of the maxillary sinus (4%). Irrigation of the wound was performed, and all 25 ROM patients received IV liposomal amphotericin B (L-AMB). Conclusion Post-COVID-19 status with elevated blood sugar levels was a major risk factor for ROM. Early diagnosis, debridement, L-AMB, retrobulbar AMB deoxycholate, and exenteration are the possible solutions.

Ocular involvement—An unusual initial presentation of chronic myeloid leukemia: A case report

ABSTRACT Chronic myeloid leukemia (CML) patients frequently exhibit systemic symptoms such as fatigue, abdominal discomfort, weight loss, and fever but rarely can have atypical initial presentation in the form of ophthalmic manifestations, which can precede the diagnosis of the primary malignancy. We describe a case of a 29-year-old male who presented in our ophthalmology out-patient department (OPD) with complaints of painless, diminution of vision, which was sudden in onset in right eye (RE) and loss of vision in left eye (LE) for four and seven days, respectively. There had been a history of loss of weight and appetite for the past 2 months. The visual acuity (VA) recorded was finger counting two meters in RE and perception of light in LE with an inaccurate projection of rays in both eyes (BE). The anterior segment evaluation of both eyes (BE) was normal. Fundus revealed multiple elevated yellow subretinal lesions with exudative detachment in the RE and no view in the LE. Ultrasound-Brightness (USG B) scan in the LE revealed multiple hyperreflective echoes likely vitreous hemorrhage. Optical coherence tomography (OCT) showed subretinal hyperreflectivity with surrounding edema in RE suggestive of leukemic infiltrates. On further systemic investigations, chronic myeloid leukemia-chronic phase (CML-CP) was detected; hence, the diagnosis of RE exudative retinal detachment (RD) and LE vitreous hemorrhage with CML-CP was made. Ophthalmic involvement is more often seen in acute than chronic leukemia, which makes the diagnosis challenging. We describe a unique case of a young patient with CML-CP who initially presented with ocular involvement preceding systemic diagnosis. This case report illustrates the importance of a primary care physician or an ophthalmologist in the early diagnosis and prompt management of hematological malignancy, as ophthalmic manifestations may be a rare initial presenting feature in CML-CP. These conditions require urgent referral to a hematologist by a primary care physician in the view of early commencement of therapy.

Subhyaloid hemorrhage in Evans Syndrome.

Evans syndrome is a rare disorder characterized by autoimmune hemolytic anemia and immune thrombocytopenia. We report the first case of ophthalmic involvement in a pediatric patient with Evans syndrome, in which painless vision loss was the presenting symptom. A 15-year-old female presented with acute painless loss of vision in her right eye and was found to have bilateral subhyaloid hemorrhages. She was treated with intravenous steroids and transitioned to hydroxychloroquine. Her retinal hemorrhages resolved and her vision improved. Nontraumatic subhyaloid hemorrhage is a rare cause of vision loss in children. Evans syndrome should be considered in the differential diagnosis of such patients when hematologic abnormalities are present.

Mysterious Association of Systemic Lupus Erythematosis with Perry Romberg Syndrome

Parry Romberg syndrome (PRS), also referred to as progressive hemifacial atrophy, progressive facial hemiatrophy, or idiopathic hemifacial atrophy, was first described by C Parry and M Romberg.1 It manifests in the first two decades in morphologically normal-born individuals. It commonly affects one or more dermatomes in the trigeminal nerve territory. It has an early onset of ophthalmic and neurological involvement and a variable maxillo-facial or cardiac involvement. It is an idiopathic, gradually progressive craniofacial asymmetry, following the atrophy of subcutaneous tissue, muscles, osseous, and cartilaginous structures. Ophthalmic involvement occurs in up to 35% of cases2. Neurological symptoms manifest in 15 to 20% of cases3.

Bilateral acute angle closure attack precipitated with dengue fever

Dengue is known to cause varied ocular problems from mild-to-severe sight threatening. We present the case of a 63-year-old female patient with bilateral shallow anterior chamber and acute angle closure attack precipitated during the convalescent phase of dengue infection. She arrived at the emergency department at midnight with a history of vomiting, headache, weakness, and pain in the left eye (LE). Her diagnosis of dengue fever was supported by specific serological testing. On ocular examination, the anterior chamber of both eyes was noticeably shallow and her LE felt stony hard on digital palpation. Intravenous mannitol 300 mL over 45 min were given stat followed by topical medications. In the morning, intraocular pressure measured was 10 mmHg (right eye [RE]) and 26 mmHg (LE). After thorough examination, she was diagnosed with occludable angle in RE and angle closure in LE after gonioscopy. Neodymium-doped Yttrium Aluminum Garnet laser peripheral iridotomy was done in both eyes. She was relieved of symptoms. The varied spectrum of possible ocular symptoms should prompt the ophthalmologist to suspect the potential involvement of eye in dengue fever. Detailed history taking is of utmost importance in early diagnosis of some rare presentation of dengue-related ophthalmic involvement. Increased awareness of dengue-related ophthalmic complications among clinicians involved in the care of patients with dengue would facilitate prompt ophthalmologic assessment and emergency medical care.

Hypertrophic pachymeningitis due to IgG4-related disease (RD-IgG4). A case report

IntroductionHypertrophic pachymeningitis (HP) is a clinico-radiological entity characterized by a thickening of the dura mater that may be focal or diffuse and manifested by a variety of neurological syndromes. Aetiologically, it is classified as infectious, neoplastic, autoimmune, and idiopathic. Many of these formerly idiopathic cases have been shown to fall into the spectrum of IgG4-related disease. ObjectiveTo describe the case of a patient attended for neurological involvement due to hypertrophic pachymeningitis with initial diagnosis of inflammatory myofibroblastic tumour and final diagnosis of IgG4-related disease. CaseA 25-year-old woman with neurological symptoms of 3 years’ evolution characterized initially by right hypoacusis, evolving with headache and diplopia. Magnetic resonance imaging (MRI) of the encephalon showed pachymeningeal thickening with involvement of vasculo-nervous structures in the tip of the cerebellum, cavernous sinus, ragged foramen, and optic chiasm. The patient presented for consultation with the result of an incisional biopsy that reported a proliferative lesion combining fibrous elements of fascicular or swirling arrangement with collagenized streaks with dense, lymphoplasmacytic infiltrate and some macrophages, with negative staining for ALK 1, with a diagnosis of inflammatory myofibroblastic tumour.Due to suspicion of IgG4-related disease (IgG4-RD) the biopsy was sent for review and pertinent complementary studies were requested. Biopsy reviewNon storiform fibrosis, predominantly lymphoplasmacytic infiltrate, histiocytes, and polymorphonuclear infiltrate in sectors, without granulomas or atypia. Staining for germs negative. Immunohistochemistry with 50–60 IgG4+/HPF cells and range of 15%–20%, CD68+ in histiocytes, CD1a−, S100−.The patient presented deterioration of visual acuity due to ophthalmic nerve involvement, so glucocorticoid treatment was started in pulses and rituximab with regression of symptoms and imaging improvement of the lesions. ConclusionHP is a clinical imaging syndrome with variable symptoms and aetiologies that poses a diagnostic challenge.In this case the initial diagnosis was inflammatory myofibroblastic tumour, which is a neoplasm of variable behaviour, locally aggressive, and can metastasize; it is one of the main differential diagnoses of IgG4-related disease because they share anatomopathological features, including storiform fibrosis.IgG4-RD is an immune-mediated condition that can have single or multiple involvement. Its diagnosis is complex when it presents with single organ involvement or in non-typical organs (CNS, meninges) in which data are scarce, as in the case of our patient with single organ involvement of the CNS.Although there are classification criteria to guide non-specialists in the diagnosis, the sum of the clinical picture, imaging, laboratory, pathological anatomy, and immunohistochemistry will always be evaluated together for a definitive diagnosis.

Ophthalmic Manifestations of Multisystem Inflammatory Syndrome in Children

Abstract Objective The aims of this study were to determine the prevalence and clinical features of ophthalmic involvement in multisystem inflammatory syndrome in children (MIS-C) and to evaluate its association with other organ system involvement and the severity of the disease. Methods The demographic data and information on the ophthalmologic and other systemic organ manifestations, laboratory findings, treatment modalities, and clinical outcomes of 97 patients with MIS-C were retrospectively obtained from their hospital records. Sixty-two patients with MIS-C who were examined by ophthalmologists were included in the study. Statistical analysis was performed using R version 3.6.0, and a p-value &lt; 0.05 was accepted as statistically significant. Results The patients' median age was 82 months (range, 11–204 months). Of the patients, 62.9% were male. The most common systemic involvements were mucocutaneous (83.9%) and cardiovascular (82.3%). Kawasaki disease was clinically observed in 71% of the patients (incomplete form, 53.2%). Ophthalmic involvement was observed in 39 patients (62.9%). Thirty-two patients (51.6%) had conjunctival hyperemia; 29 (48.4%) lid edema; 7 follicular conjunctivitis; 3 uveitis; 2 subconjunctival hemorrhage; and 1 episcleritis. The patients with ophthalmic involvement were 6.4 times (95% confidence interval [CI], 1.49–27.48; p = 0.013) more likely to exhibit cardiac involvement and 3.53 times (95% CI, 1.35–9.63; p = 0.012) more likely to have severe disease. Conclusion Conjunctival hyperemia, lid edema, and follicular conjunctivitis were observed in at least half of the patients with MIS-C, and those with ophthalmic involvement had a higher risk of cardiac involvement or severe disease.

Analysis of google trends and search results for ophthalmic symptoms of monkeypox.

In July2022, the World Health Organization (WHO) declared monkeypox virus's global spread a "public health emergency of international concern." About a quarter of monkeypox cases feature ophthalmic symptoms. We assessed trends in worldwide search interest in monkeypox ophthalmic involvement and inclusion in online search engine queries. The following keywords were searched on Google Trends from April 1, 2022, to August 12, 2022: monkeypox + eye, pink eye, eye infection, eyelid, vision, blurry vision, vision loss, blindness, eye symptoms, eye problems, eye pain, eye redness, conjunctivitis, conjunctiva, cornea, keratitis, corneal ulcer, and blepharitis. We analyzed trends, correlated search interest with case count data, and compared popularity of search terms via nonparametric Mann-Whitney-U analysis. Inclusion of ophthalmic symptoms in Google search results for "monkeypox symptoms" was assessed. "Monkeypox eye" had the highest averagesearch interest worldwide and in the United States. Search interest peaked between mid-May and late July 2022. When compared to interest in "monkeypox rash," the most searched monkeypox symptom, the average interest in "monkeypox eye" was lower (p < 0.01). Of the first 50 results from the Google search of "monkeypox symptoms," 10/50 (20%) mentioned ophthalmic symptoms. 6/50 (12%) mentioned the eye as a route of virus transmission. Search interest in monkeypox ophthalmic symptoms corresponds with geographic and temporal trends, i.e., timing and location of the first reported non-endemic cases and WHO announcement. Although ophthalmic symptoms are not as widely searched currently, inclusion in public health messaging is key for diagnosis, appropriate management, and reduction of further transmission.

Mercury intoxication and ophthalmic involvement: An update review.

Human intoxication after mercury exposure is a rare condition that can cause severe damage to the central nervous, respiratory, cardiovascular, renal, gastrointestinal, skin, and visual systems and represents a major public health concern. Ophthalmic involvement includes impaired function of the extraocular muscles and the eyelids, as well as structural changes in the ocular surface, lens, retina, and optic nerve causing a potential irreversible damage to the visual system. Although, there are many pathways for poisoning depending on the mercury form, it has been suggested that tissue distribution does not differ in experimental animals when administered as mercury vapor, organic mercury, or inorganic mercury. Additionally, visual function alterations regarding central visual acuity, color discrimination, contrast sensitivity, visual field and electroretinogram responses have also been described widely. Nevertheless, there is still controversy about whether visual manifestations occur secondary to brain damage or as a direct affectation, and which ocular structure is primarily affected. Despite the use of some imaging techniques such as in vivo confocal microscopy of the cornea, optical coherence tomography (OCT) of the retina and optic nerve, and functional tests such as electroretinography has helped to solve in part this debate, further studies incorporating other imaging modalities such as autofluorescence, OCT angiography or adaptive optics retinal imaging are needed. This review aims to summarize the published structural and functional alterations found in the visual system of patients suffering from mercury intoxication.

The eye is a common site of granulomatosis with polyangiitis. A collaborative study

BackgroundOcular manifestations of granulomatosis with polyangiitis (GPA) have been reported in a limited number of studies and with largely variable frequency. Here we report on the clinical, diagnostic, and therapeutic features of a cohort of 63 GPA patients, with particular regard to 22 of them with ophthalmic involvement (35%).MethodsClinical manifestations, results of immunological findings, histopathological pictures, imaging data, Birmingham Vasculitis Activity Score, therapeutic regimens, and outcomes were retrospectively analyzed. At diagnosis, in addition to a structured clinical assessment, all patients underwent a comprehensive ophthalmologic examination.ResultsThe most frequently involved organs were kidneys, lungs, ear/nose/throat, and eyes. Ocular manifestations were bilateral in 32%. The three most commonly diagnosed ophthalmologic manifestations were scleritis (36%), retro-orbital pseudotumor or orbital mass (23%), and episcleritis (13%). Ocular and systemic involvement were simultaneously present at onset in 41% of the patients; systemic involvement was followed by ocular lesions in 36%; ocular inflammation was followed by systemic manifestations in 18%; and an orbital mass in the absence of systemic disease characterized 5%. Glucocorticoids plus cyclophosphamide and glucocorticoids plus rituximab were the combined therapies most frequently employed during remission induction and remission maintenance, respectively. Persistent ophthalmologic and extra-ocular remissions were achieved in 77 and 64% of the patients, respectively. One to three systemic relapses were diagnosed in 7 patients (31.8%). At the last follow-up, a visual outcome 20/40 or better in 31 (70%) of 44 eyes was determined.ConclusionsThe eye was involved in over one third of our patients with GPA. Increased awareness, early diagnosis, and multi-specialty collaboration are critical in achieving a favorable outcome of GPA.
