Ocular Manifestations of Acute Secondary Angle Closure Associated With Lens Subluxation

Purpose:To evaluate the clinical characteristics and ocular features of patients with acute secondary angle closure, associated with lens subluxation (ASAC-LS).Methods:We performed a retrospective study at the EENT Hospital of Fudan University, Shanghai, China. A total of 41 affected eyes from 41 patients were enrolled in this study. Furthermore, 20 affected eyes were part of the ASAC-LS cohort and 21 affected eyes were included in the acute primary angle closure (APAC) cohort. The best-corrected visual acuity (BCVA), intraocular pressure (IOP), axial length (AL), minimum corneal curvature (K1), maximum corneal curvature (K2), and anterior chamber depth (ACD) were measured and compared between the 2 cohorts. In addition, inter-eye (intraindividual) comparison was performed.Results:The ASAC-LS cohort exhibited younger ages, more frequent trauma history (35%), lower IOP (27.43 ± 13.86 mmHg vs. 41.27 ± 10.36 mmHg), longer AL (23.96 ± 2.60 vs. 22.49 ± 0.77 mm), shallower ACD (1.28 ± 0.38 vs. 1.58 ± 0.23 mm), and bigger ACD differences (0.99 ± 0.52 vs. 0.15 ± 0.19 mm), as compared with the APAC cohort (all p < 0.05). Moreover, eyes from the lens subluxation cohort experienced worse BCVA, higher IOP, and shallower ACD than their matched unaffected eyes (all p < 0.05). Although longer AL, shallower ACD, and bigger ACD differences were strongly correlated with lens subluxation in a univariate logistic regression analysis, only the ACD difference remained significant in the multivariate model (p = 0.004, OR = 1,510.50). Additionally, according to the receiver operating characteristic (ROC) curve analysis, both ACD and ACD differences had greater value in the differential diagnosis of ASAC-LS and APAC, with a cut-off value of 1.4 and 0.63 mm, respectively.Conclusions:Shallower ACD and larger ACD differences provide the promising diagnostic potential for patients with ASAC-LS.

HIPERTENSÃO OCULAR SECUNDÁRIA À LUXAÇÃO DE CRISTALINO PARA CÂMARA ANTERIOR NA SÍNDROME DE MARFAN

Marfan syndrome (MFS) is a rare autosomal dominant metabolic disorder, caused by mutations in the gene responsible for coding the fibrillin-1 protein. It is characterized by cardiovascular, musculoskeletal and ocular manifestations. The purpose of this report was to present a rare ophthalmologic complication in a patient with MFS. Female, 51 years old, attended the emergency room complaining of severe pain, low visual acuity and hyperemia in the right eye, started two days before. Biomicroscopy: ectopia lentis (luxated) for anterior chamber; Tonometry: 56 mmHg. Hypotensive drugs were prescribed which reduced intraocular pressure (IOP) to 8 mmHg. Referred for emergency surgery (facectomy without IOL implantation) in order to avoid further damage to the cornea and optic nerve. In the post operative period, presented IOP control and improved VA to 20/50. Multidisciplinary follow-up is necessary in patients with MFS, enabling early diagnosis, which can prevent and minimize any complications.

Anterior ischemic optic neuropathy as a rare manifestation of COVID-19: a case report

Aim: A variety of manifestations in different organs could be associated with severe COVID-19; for example, ocular manifestations. Case report: A 52-year-old male complaining of sudden onset unilateral painless vision loss in the right eye for 1 month (started just 1 week after COVID-19 remission) came to the ophthalmology clinic. On further evaluations, he was diagnosed with anterior ischemic optic neuropathy (AION). Considering his past history and the result of evaluations, the hypothesis of association between AION and COVID-19 was proposed. Results & discussion: Ocular and neurologic manifestations of COVID-19 are more likely to happen in patients with more severe conditions. Complications occur secondary to two basic mechanisms including severe inflammatory response and hypercoagulable state. Conclusion: Our findings indicated that non-arteritic AION is another manifestation of microangiopathic/thrombotic events which may occur in the course of COVID-19.

A Case of Angioid Streaks in Congenital Dyserythropoietic Anaemia Type II

The authors describe a case report of retinal angioid streaks (AS) in a patient with congenital dyserythropoietic anaemia (CDA) type II and compare the retinal findings to those of an affected first-degree relative without ocular manifestations of the disease. A 52-year-old man with a confirmed diagnosis of CDA type II has been dependent on treatment with regular transfusions and chelating agents. He presents with bilateral retinal AS. The subject’s brother, who also has CDA type II, underwent splenectomy in childhood, and has required no treatment since then. He has no ocular manifestations of the disease. To the authors’ knowledge, this is only the second time that the presence of retinal AS has been reported in a case of CDA type II. It has been reported more frequently with CDA types I and III. The milder course of disease in the subject’s brother likely accounts for the differing retinal findings. The authors explore the pathophysiology of AS in this disease, and the differential diagnosis of chelating agent toxicity. Diagnostic uncertainty around retinal findings can lead to withholding of essential systemic treatment and inappropriate ophthalmological follow-up. It is recommended that all patients with CDA undergo eye examinations.

Ocular Manifestations, Visual Field Pattern, and Visual Field Test Performance in Traumatic Brain Injury and Stroke

Purpose. To analyze ocular manifestations, visual field (VF) pattern, and VF test performance in traumatic brain injury (TBI) and stroke patients. Methods. This retrospective, cross-sectional study included 118 patients (236 eyes) with TBI and stroke who had undergone VF testing by standard automated perimetry with the central 24-2 threshold test. Clinical features including best-corrected visual acuity (BCVA), intraocular pressure (IOP), ocular manifestations, and VF test results including VF defect pattern, reliability, and global indices were analyzed and compared between the TBI and stroke patients. Results. In TBI patients, ocular manifestations included strabismus (11.1%), cataract (4.2%), and glaucoma suspect (2.8%), whereas in stroke patients, cataract (15.2%), strabismus (8.5%), diabetic retinopathy (4.9%), extraocular movement (EOM) limitation (3.0%), glaucoma suspect (3.0%), nystagmus (2.4%), drusen (1.2%), and vitreous hemorrhage (1.2%) were found. The VF test results showed that 47 eyes (85.5%) in TBI and 86 (65.2%) in stroke had VF defect; in TBI, the scattered pattern was the most common (56.4%), followed by homonymous hemianopsia (14.5%), homonymous quadrantanopia (10.9%), and total defect (3.6%), whereas in stroke, homonymous hemianopsia was the most common (31.8%), followed by scattered pattern (16.7%), homonymous quadrantanopia (12.1%), and total defect (4.5%). Only 15 eyes (27.3%) in TBI and 32 (24.2%) in stroke showed reliable VF indices. The mean deviation (MD) was −10.5 ± 7.1 dB in TBI and −9.5 ± 6.8 dB in stroke, and the pattern standard deviation (PSD) was 4.9 ± 3.3 dB in TBI and 6.1 ± 3.9 dB in stroke, without statistically significant differences between the two groups. Conclusion. Various ocular manifestations were found, and a considerable proportion of patients were experiencing VF defects and showed unreliable VF test performance. Our findings suggest that accurate evaluation and rehabilitation of visual function should be a matter of greater concern and emphasis in the management of TBI and stroke patients, besides systemic diseases.

Clinico-Demographic Profile of Covid-19 Patients Admitted in COVID- HDU and its Association with Conjunctivitis

Introduction: The outbreak of coronavirus diseases 2019 (Covid-19) caused by SARS-COV-2 which started in Wuhan china led to an alarming level of spread and severity. In Nepal, the first case of COVID-19 was reported on 23.1.2020 and has become a global health crisis since then. The clinical presentation and outcome of patients with COVID-19 have been variable in different countries and therefore it is important to analyze as well as document the clinical behaviors of this disease in the local population so we have reported the clinic-epidemiological profile, outcome, and its association with conjunctivitis during the second wave of this pandemic which hit Nepal badly hoping this study will be helpful to tackle the future surges of COVID-19 as well. Materials and Methods: This was a prospective, single-center study where the data regarding epidemiology, demography, common clinical presentation as well as management and outcome of COVID-19 Patients were retracted and analyzed. Results: A total of 238 COVID-Positive patients were admitted out of which 60% were male and 39.9% people belonged to Dang valley itself with dyspnea (67.2%) was the commonest symptoms followed by fever in 59.7% of patients. Out of these patients 9 patients presented with ocular symptom conjunctivitis. Conclusions: Mild conjunctivitis manifesting as conjunctival congestion is common and one of the major ocular manifestations in COVID -19 positive patients.

Ocular manifestations and clinical profile of multisystemic inflammatory syndrome in children during COVID-19 pandemic

Background: Multisystemic inflammatory syndrome in children (MIS-C) is a new childhood disease, which is associated with Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2). To evaluate ocular manifestations and clinical characteristics of MIS-C during COVID-19 pandemic.Methods: A cross-sectional observational study was conducted among 48 MIS-C patients (≤19 years) at Burdwan Medical college and hospital in West Bengal, India from April 2021 to June 2021. History taking, clinical examination and necessary investigations of all the patients were done.Results: Out of 48 patients, 18 patients (37.5%) presented with conjunctivitis, 4 (8.3%) with eyelid swelling, 2 (4.2%) with episcleritis, 2 (4.2%) with papilledema, 1 (2.1%) with subconjunctival haemorrhage, 1 (2.1%) with uveitis, 1 (2.1%) with retinitis and 4 (8.3%) with decreased vision. Other clinical manifestations included fever, skin rash, loose stool, vomiting, abdominal pain, cough, peripheral oedema, myalgia, breathlessness, altered sensorium, cervical lymphadenopathy, shock, oliguria, chest discomfort and joint swelling. Serum inflammatory, coagulation and cardiac markers were deranged.Conclusions: Ocular and other clinical manifestations in MIS-C were due to post-COVID immuno-dysregulation resulting in “cytokine storm” and hyper-inflammatory response. Conjunctivitis was the most common ocular manifestation. There was a positive correlation between severity of the conjunctival hyperaemia and level of serum inflammatory markers.
