Acute and severe ocular manifestations of a patient with Stevens-Johnson Syndrome in RSUD Wangaya: a case report

Background: Stevens-Johnson syndrome is a severe mucocutaneous disorder with high mortality rates and potentially life-threatening. Ocular manifestations in SJS occurred up to 81%, with manifestation ranging from conjunctiva hyperemia, cicatrizing conjunctivitis with symblepharon, corneal ulceration, corneal blisters and perforation, which can potentially lead to permanent vision loss.
 
 Case Description: A 34-year-old male patient was being consulted to ophthalmologist department with the diagnosis Stevens-Johnson syndrome, he was complaint bilateral upper and lower eyelid palpebral conjunctiva adhesion to bulbar conjunctiva. The ophthalmological examination cannot be examined due to the adhesion then the patient was performed bilateral symblepharon separation of the eyelid using blunt-tip of surgical scissors under local anesthesia. After the procedure, the visual acuity was around 3/60 for both eyes. The anterior segment examination in both eyes showed that the palpebral was edema, peeling of the skin. The conjunctiva appears to be chemosis, conjunctival injection, with mucopurulent secret in both eyes. The patient was treated with antibiotic combined with steroid eye ointment and eye drop. 
 Conclusion: Ocular manifestations of SJS are mostly mild-moderate. However, several cases possess grave complication and may progress to vision loss. Treatment for the ocular sequelae can reduce the risk of long-term visual morbidity. Knowing the etiology along with the progression of the disease is necessary for early diagnosis and prompt treatment.

Comorbidities in Corneal Refractive Surgery Candidates: A Cross-Sectional Study

Background: Individuals with refractive errors sometimes have other associated ocular and systemic abnormalities. Objectives: To explore ocular and systemic comorbidities in Corneal Refractive Surgery (CRS) candidates and to examine any contraindications for CRS. Methods: This was a cross-sectional study. Medical records of individuals who underwent a refractive surgery screening at Chiang Mai University LASIK Center, Chiang Mai, Thailand, were reviewed. All clinical data of the initial visit were evaluated. Eyes with a history of CRS and phototherapeutic keratectomy were excluded. Results: A total of 1,167 cases (2,334 eyes) were recruited, out of which 643 cases were females (55.09%). Myopia was the most common type of refractive error (2,120 eyes, 90.83%), and 868 (40.94%) eyes had high myopia. Approximately 45% (n=526) of the cases had worn contact lenses. The five most common ocular comorbidities (eyes, proportion) included keratoconus suspect (297, 12.72%), cataract (246, 10.53%), dry eye/probable dry eye (208, 8.91%), glaucoma suspect (184, 7.88%), and amblyopia (149, 6.38%). The most common systemic conditions that affected choices or outcomes of CRS were hypertrophic scar/keloid (169 cases, 14.48%) followed by allergy/asthma (127 cases, 10.88%). A total of 1,028 eyes (44.04%) were excluded from CRS, mainly due to abnormal corneal topography (470/1,028 eyes, 45.72%). Conclusion: Most refractive candidates were myopic and contact lens wearers. Serious ocular sequelae from myopia and contact lens use were not uncommon. Additionally, systemic diseases regularly affected the CRS options. The most common contraindication for CRS was abnormal corneal topography. Our study, thus, emphasizes the need for thorough ocular and systemic screenings of refractive candidates.

Ophthalmic involvement in PHACES syndrome: prevalence, spectrum of anomalies, and outcomes

To highlight prevalence, spectrum of anomalies, and outcome of ophthalmic involvement in PHACES syndrome (posterior fossa malformations, infantile hemangiomas, arterial, cardiac, eye, and sternal anomalies). A retrospective, noncomparative, single-institution observational case series of children with PHACES was conducted from 2000 to 2019. Data on ocular presentations, interventions and visual outcomes were collected. Primary outcome measures were the frequency and spectrum of ocular involvement. Secondary outcomes were final visual acuity, long-term ocular sequelae, and frequency of surgical interventions. A total of 43 infants had PHACES, of whom 29 (67%) had periocular infantile facial hemangiomas (IFH) and 6 (14%) had primary ocular anomalies that were always ipsilateral to the IFH. Five patients (12%) met ocular PHACES-specific diagnostic criteria, including optic nerve (3), retinal vascular (1) and lenticular (2) anomalies. Non-PHACES-specific abnormalities were Peters anomaly (1), persistent pupillary membranes (2), dysmorphic optic nerves (1), and iris/choroidal hemangiomas (2). IFH-related periocular abnormalities were frequent: ptosis (29), proptosis (9), strabismus (6). Surgery was required in 8 of the 29 children: (strabismus [6], entropion [2], ptosis [2], and optical iridectomy [1]), all of whom had orbital/conjunctival hemangioma (P = 0.03). Final visual acuity (follow-up, 8.7 years) ranged between 20/20 and 20/80 in 26 of 29 patients. All patients with visual acuity worse than 20/200 (3/29 [10%]) had structural anomalies. Two-thirds of infants with PHACES have periocular IFH causing vision compromising complications of amblyopia and strabismus. Structural ocular anomalies exist in 1 of 7 patients and are always ipsilateral to the IFH. Long-term ophthalmic monitoring and management is required, and the majority of patients obtain good visual outcomes.

Ocular sequelae in severe COVID-19 recovered patients of second wave.

Purpose:To evaluate the retinal microvascular changes in patients, recovered from severe COVID-19 during the second wave of the pandemic in North India.Methods:In this observational cross-sectional study, 70 eyes of 35 patients who recovered from severe COVID-19 during the second wave underwent detailed ophthalmic evaluation 4–6 weeks after discharge. Twelve controls were also enrolled, and the difference in the findings between the case and control groups on optical coherence tomography (OCTA) were studied.Result:The ages of study participants ranged from 27 to 60 years with the male:female ratio being 1.05:1. The fundus changes suggestive of ischemia in the form of cotton wool spots and vascular tortuosity were seen in 25 eyes (35.71%). Increased venous tortuosity was the most common finding seen in 23 eyes (32.85%), of which 10 eyes (28.57%) had concurrent hypertensive retinopathy (HTR) changes. There was a significant reduction in the mean vascular density (VD) and perfusion density (PD) for both the superficial capillary plexus (SCP) and deep capillary plexus (DCP) at inner, outer ring, and whole (P < 0.05). Foveal avascular zone was significantly enlarged in both the SCP (P = 0.01) and the DCP (P = 0.03). The mean ganglion cell-inner plexiform layer (GC-IPL) was significantly reduced in comparison to controls (P < 0.001).Conclusion:Severe COVID-19 can result in microvascular changes at the macula in the form of reduction in vascular and perfusion density, which can be evaluated using OCTA. As structural changes precede functional changes, a close watch is recommended in patients showing compromise in retinal microvasculature.

Ocular events following the surge of cough and cold medications use during the Omicron outbreak in Hong Kong.

To the Editor Coronavirus disease 2019 (COVID-19) situation worsened since the Omicron spread in Hong Kong,1 numerous infected but mildly ill patients accumulated in our community.2,3 We report a surge in acute primary angle closure (APAC) since the local outbreak of Omicron. This letter highlights the potential ocular sequelae of antitussive and nasal decongestants usage and serves to alert practitioners to wear adequate personal protective equipment upon attending APAC cases. In second to third week of March, we encountered consecutive eight eyes (seven patients) of APAC (Table 1) in our hospital, which was more than triple of usual. Five (71.4%) were without past ocular history. The remaining two (28.6%) were known to be primary angle-closure suspect (PACS). All admitted prior cough mixture or cold medications uses for relief of upper respiratory tract symptoms, including promethazine compound linctus, diphenhydramine compound linctus, actified syrup (pseudoephedrine and triprolidine), chlorpheniramine and different over-the-counter anti-histamine and nasal decongestant. Four (57.1%) patients were known cases of COVID-19, when the first week of March was the peak of the Omicron surge. The remaining three (42.9%) were not yet tested upon attendance, yet symptomatic with cough, sputum and runny noses. All were SARS-CoV-2 RNA positive by polymerase chain reaction subsequently. Investigation gonioscopy of the contralateral eye revealed PACS in all cases.

POSTERIOR SEGMENT OCULAR FINDINGS IN CRITICALLY ILL PATIENTS WITH COVID-19.

To describe ophthalmological fundoscopic findings in patients with COVID-19 admitted to the intensive care unit of the largest third-level referral center for COVID-19 in Mexico City. In this cross-sectional single-center study, consecutive patients admitted to the intensive care unit with a diagnosis of COVID-19 underwent fundus examination with an indirect ophthalmoscope. Clinical photographs were taken using a posterior-pole camera. We explored the association between ocular manifestations and demographic characteristics, inflammatory markers, hemodynamic factors, and comorbidities. Of 117 patients examined, 74 were men; the median age was 54 years (range: 45-63 years). Forty-two patients had ophthalmological manifestations (unilateral in 23 and bilateral in 19), and 10 of these patients had more than one ophthalmological manifestation. Ocular findings were papillitis (n = 13), cotton wool spots (n = 12), retinal hemorrhages (n = 5), retinal nerve fiber layer edema (n = 8), macular whitening (n = 5), retinal vascular tortuosity (n = 4), papillophlebitis (n = 3), central retinal vein occlusion (n = 1), and branch retinal vein occlusion (n = 1). Ocular fundus manifestations were not associated with demographic characteristics, inflammatory markers, hemodynamic factors, or comorbidities. More than one-third of patients with severe COVID-19 had ophthalmological manifestations. The most frequent fundoscopic findings were optic nerve inflammation, microvasculature occlusion, and major vascular occlusions. We recommend long-term follow-up to prevent permanent ocular sequelae.

Structural and Functional Evaluation of Meibomian Glands and Its Correlation With Dry Eye Parameters in Stevens-Johnson Syndrome

To evaluate the structural and functional changes of the meibomian gland and correlate with subjective and other objective dry eye parameters in Stevens-Johnson syndrome (SJS) patients. Prospective cross-sectional study. This study recruited 60 patients (120 eyes) with SJS and chronic ocular sequelae. All patients underwent evaluation with a Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire, tear osmolarity, Keratograph 5M, LipiView, Schirmer's 1, corneal staining, Meibum Expression score (MES, 0-3), and Meibum Quality score (MQS, 0-3). The meibomian gland dropout area (meiboscore) was calculated for both lids and graded on a 4-point scale from 0 to 3. The mean age of patients (n=60) was 31.08 ± 12.94 years; 25 were males. The commonest cause for SJS, in 51 patients (85%), was drug reaction. The mean tear osmolarity, lipid layer thickness (LLT), Schirmer's test-1, and tear break-up time was 322.70 ± 17.82 mOsm/L, 53.07 ± 27.0 nm, 6.62 ± 5.74 mm, 3.38 ± 1.90 seconds, respectively. Out of 240 eyelids (both upper and lower), 160 (65%) eyelids revealed severe meibomian gland loss. The mean upper and lower lid gland loss was 77.36 ± 28.82% and 76.65 ± 29.33%, respectively, Seventy-four eyelids (61%) had no expressible glands. Meiboscore showed positive correlation with SPEED (P < .001), corneal staining scores (P < .001), MES (P < .001), and MQS (P < .001). The LLT negatively correlation with SPEED (P < .01), meiboscore (P < .001), MES (P < .01), and MQS (P < .001). Significant alterations in anatomical and functional aspects of the meibomian gland are seen in SJS. The high meiboscore, MES, MQS, and decreased LLT contributed to the worsening dry eye state, as seen by their correlation with other dry eye parameters. This study highlights the need to evaluate meibomian gland structure and function in patients with chronic ocular sequelae of SJS.

Functional Ophthalmic Factors Associated With Extreme Prematurity in Young Adults

Children born preterm (<37 weeks' gestation) have a higher risk of visual impairment and ocular morbidities compared peers born at full term. However, the long-term ocular sequelae in adulthood for those born extremely preterm (EP), who have the highest risk of neonatal retinopathy, are unknown. To evaluate visual function and ocular morbidity in young adults born EP compared with controls born full term. This prospective cohort study of a geographically based birth cohort in the UK and Ireland born from March 1 through December 31, 1995, included 128 participants aged 19 years (born at 22-25 weeks' gestation) and 65 age-matched controls born at full term. Statistical analysis was performed from March 1, 2020, to November 26, 2021. Participants underwent eye examinations as part of a comprehensive outcome evaluation. Best-corrected visual acuity, refractive status, contrast sensitivity, color vision, prevalence of strabismus and nystagmus, and patient-reported visual function, measured using the Health Utilities Index Mark 3. The study comprised 128 participants (256 eyes; 68 female participants [53%]; mean [SD] age, 19.3 [0.5] years) and 65 age-matched controls born at full term (130 eyes; 40 female participants [62%]; mean [SD] age, 19.2 [0.5] years). Compared with control eyes, the mean (SD) best-corrected visual acuity among eyes in the EP group was significantly worse (monocular vision: -0.06 [0.14] logMAR in the control group vs 0.14 [0.38] logMAR in the EP group; P < .001; binocular vision: -0.14 [0.15] logMAR in the control group vs 0.06 [0.37] logMAR in the EP group; P < .001). Participants in the EP group had a significantly higher prevalence of strabismus (36% [46 of 127] vs 0%; P < .001), abnormal ocular motility (15% [19 of 125] vs 0%; P < .001), and nystagmus (13% [16 of 127] vs 0%; P < .001) than the control group. No significant differences between participants in the EP group and controls were observed for refractive error, contrast sensitivity, color vision, or patient-reported visual function. Among the participants in the EP group, 48% of eyes (120 of 250) had no retinopathy of prematurity (ROP), 39% (98 of 250) had ROP not requiring neonatal treatment, and 13% (32 of 250) received cryotherapy or laser ablation for ROP. Within the EP group, there was no significant difference in binocular visual function parameters, prevalence of ocular morbidity, and patient-reported visual function by neonatal ROP status. Extreme prematurity is associated with an increased prevalence of visual and ocular deficits in young adulthood; this study suggests that, for individuals born EP, visual and ocular deficits appear to be partially independent of ROP status in the neonatal period but reports similar overall visual function.

Ocular Manifestations of Sporotrichosis in a Hyperendemic Region in Brazil: Description of a Series of 120 Cases

ABSTRACT Purpose To describe 120 cases of ocular sporotrichosis. Methods Review of medical records of patients with culture-proven (from eye specimen) ocular sporotrichosis, in Rio de Janeiro, from 2007 to 2017. Results Women were more affected (61.7%) and median age was 24 years. The isolated ocular form was more frequent (75.8%). Fixed cutaneous sporotrichosis was the most commonly associated form (48.3%). Hypersensitivity reactions were observed in 10% of patients. Ocular involvement was unilateral in 98.3% of the cases, and the most frequent clinical presentation was granulomatous conjunctivitis (86.7%), followed by eyelid lesion (25%). Dacryocystitis represented 7.5% of the cases, predominantly in children (55.6%). Itraconazole was the first choice treatment (95.8%). Sequelae were observed in 23 patients (22.5%), and surgical treatment was required for most of them. Conclusion Ocular sporotrichosis can be considered a characteristic form of the zoonotic transmission, with high morbidity. Delay in initiating specific treatment is likely to increase the risk of progression to more severe forms of the disease, and development of ocular sequelae.

A Rolling Ball in the Eye

A 9-year-old girl presented to our hospital without a medical history. In the left eye, slit-lamp examination revealed that a dark brown spherical object (approximately 1.84 × 1.75 mm) was located at the inferior anterior chamber (Fig A). The 3-dimensional reconstruction showed that a free-floating “ball” could be clearly seen (Fig B). Anterior-segment OCT was performed to evaluate its position in relation to the iris (Fig C). She continues to be observed without further ocular sequela. Primary cysts of the iris pigment epithelium are uncommon, and stationary lesions rarely progress, which require no treatment (Magnified version of Fig A-C is available online at www.aaojournal.org).

Choroidal thickness in patients with systemic arterial hypertension: a systematic review and meta-analysis.

The global burden of hypertension is constantly increasing with adverse cardiovascular and ocular sequelae. The association between elevated blood pressure and choroidal thickness (CT), as assessed via optical coherence tomography (OCT), is poorly understood. Studies including hypertensive adults and normotensive controls undergoing OCT were evaluated for inclusion in this meta-analysis. The primary endpoint was CT difference between hypertensive and normotensive adults. We conducted a systematic review and after searching 1011 results from MEDLINE, ClinicalTrials.gov, medRxiv and Cochrane Library, six studies were deemed eligible and were pooled according to a random-effect model. A statistically significant reduction in choroidal thickness was found in hypertensive adults (n = 454) as compared with normotensive controls (n = 365) [mean difference: -0.77; 95% confidence intervals: (-1.20, -0.34); p = 0.0004]. The main limitations of this meta-analysis are the relatively small population included and the high statistical heterogeneity (I 2 = 87%) among the various studies. Of note, after excluding one study the heterogeneity was markedly reduced. Choroidal thickness is reduced among hypertensive subjects compared with normotensive controls. This finding mandates further examination in the context of long-term clinical outcomes.

Choroidal rupture and macular hole secondary to blunt trauma

This is a retrospective case report of a male patient referred to the PUC Campinas Hospital as a victim of blunt car trauma. On ophthalmological examination, the patient had bilateral retinal changes in the foveal region, causing low visual acuity in both eyes. Knowing that ocular trauma is the main cause of legal blindness in working-age people, this study aimed to highlight the importance of ophthalmological evaluation to provide the necessary treatment and follow-up to minimize the ocular sequelae resulting from trauma.

Acute Management of Deep Facial Burns.

Management of deep facial burns is a serious challenge for many reasons: a considerable anatomic and functional diversity is concentrated in a small space, a uniform treatment does not exist, late sequelae are frequent and may be severe, and the literature on the subject is ambiguous. To analyse management of deep facial burns. A retrospective medical chart review was conducted for 569 patients with deep facial burns hospitalized between January 2005 and January 2015. Demographic data, type, depth and size of burns, chronology and type of surgical treatment, length of hospital stay, and type and incidence of late sequelae were analysed and compared. Over 10 years, 596 patients with deep facial burns, 216 (36.24%) females and 380 (63.76%) males, aged from 5 months to 95 years (mean 39.5±26 years) were treated. The most common burn agents were hot liquids and flames. The mean total body surface area (TBSA) burned was 17±13.3%. Concomitant eye injury was detected in 63 (10.6%) patients. Priority was given to the early, meticulous, staged surgical approach aimed at sparing the survived tissues and rapid wound closure. Follow-up ranged from 3 months to 5 years. Late functional sequelae were documented for 50 (8.38%) patients and ocular sequelae - for 33 (5.54%) of them. There was no incidence of secondary corneal perforation or definitive loss of vision. Adequate and up-to-date acute management of deep facial burns based on early, judicious, surgical approach could limit initial damage and reduce late sequelae.

Multi-state model for predicting ocular progression in acute Stevens-Johnson syndrome/toxic epidermal necrolysis.

This study aimed to clarify the etiologic factors predicting acute ocular progression in SJS/TEN, and identify patients who require immediate and intensive ophthalmological treatment. We previously conducted two Japanese Surveys of SJS/TEN (i.e., cases arising between 2005-2007 and between 2008-2010), and obtained the medical records, including detailed dermatological and ophthalmological findings, of 230 patients. Acute ocular severity was evaluated as none, mild, severe, and very severe. A multi-state model assuming the Markov process based on the Cox proportional hazards model was used to elucidate the specific factors affecting the acute ocular progression. Our findings revealed that of the total 230 patients, 23 (24%) of 97 cases that were mild at initial presentation worsened to severe/very severe. Acute ocular progression developed within 3 weeks from disease onset. Exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) and younger patient age were found to be statistically significant for the progression of ocular severity from mild to severe/very severe [hazard ratio (HR) 3.83; 95% confidence interval (CI) 1.48 to 9.91] and none to severe/very severe [HR 0.98; 95% CI 0.97 to 0.99], respectively. The acute ocular severity score at worst-condition was found to be significantly correlated with ocular sequelae. Thus, our detailed findings on acute ocular progression revealed that in 24% of SJS/TEN cases with ocular involvement, ocular severity progresses even after initiating intensive treatment, and that in younger-age patients with a history of exposure to NSAIDs, very strict attention must be given to their ophthalmological appearances.

730. Ocular Involvement Associated with Rickettsial Infection

BackgroundRickettsiosis, a re-emerging disease, is characterized with a myriad clinical symptoms and various manifestations. Ocular involvement is often misdiagnosed since it’s rarely symptomatic. It especially involves the posterior segment. We aimed to study the clinical, laboratory and therapeutic features of ocular involvement associated with rickettsial infection.MethodsWe encountered a retrospective study including all patients hospitalized for rickettsial infection with ocular involvement in the infectious disease department between 2007 and 2020. The diagnosis was confirmed based on serology (seroconversion) and/or positive polymerase chain reaction for Rickettsia in skin biopsy.ResultsA total of 24 patients were included with a mean age of 40±12 years. There were 13 women (54.2%). Sixteen patients sought medical care during the warm months, from June to October (66.6%). The revealing clinical signs were febrile maculopapular skin rash (79.2%), cephalalgia (54.2%) and arthralgia (33.3%). Five patients had visual loss (20.8%). Physical examination revealed conjunctival hyperemia (37.5%) and pathognomonic eschar (29.1%). Laboratory investigations revealed elevated liver enzymes (79.1%), thrombocytopenia (75%) and cholestasis (58.3%). Ocular involvement was unilateral in 14 cases (58.3%). Retinitis was the most common manifestation (70.8%), followed by anterior uveitis (20.8%). Retinal fluorescein angiography, performed in ten cases (41.6%), confirmed retinitis in 8 cases (80%). Both retinal vasculitis and papillary hyperfluorescence were noted in two cases (20%). Patients received doxycycline in 21 cases (87.5%) and fluoroquinolones in three cases (12.5%). The median duration of treatment was 7[6-15] days. The disease evolution was favourable in all cases (100%). No ocular sequelae were noted. Complications were noted in two cases (8.2%) represented by thrombophlebitis (one case) and recurrent seizures (one case). ConclusionSystematic fundus examination should be performed in front of suspected rickettsiosis, even in the absence of ocular symptoms and signs. It provides clinical clues to promptly diagnose and treat rickettsiosis.Disclosures All Authors: No reported disclosures

Ocular Sequelae in a Population-Based Cohort of Youth Diagnosed With Diabetes During a 50-Year Period

Despite the increasing prevalence of type 2 diabetes (T2D) diagnosed in childhood, little is known about the natural history of ocular sequelae in youth-onset T2D compared with type 1 diabetes (T1D). To assess the risk of developing diabetes-associated ocular complications among youth diagnosed with diabetes. This retrospective, population-based medical record review included all residents of Olmsted County, Minnesota (95.7% White in 1990), diagnosed with diabetes at younger than 22 years (hereinafter referred to as children) from January 1, 1970, through December 31, 2019. Risk of developing ocular complications over time. Among 1362 individuals with a diagnostic code of diabetes, medical record reviews confirmed a diagnosis of T1D or T2D in 606 children, of whom 525 (86.6%) underwent at least 1 eye examination (mean [SD] age at diabetes diagnosis, 12.1 [5.4] years; 264 [50.3%] male). Diabetes-associated ocular complications occurred in 147 of the 461 children (31.2%) with T1D and in 17 of the 64 children (26.6%) with T2D. The hazard ratio illustrating the risk between T2D and T1D rates was 1.88 (95% CI, 1.13-3.12; P = .02) for developing any diabetic retinopathy (nonproliferative or greater), 2.33 (95% CI, 0.99-5.50; P = .048) for proliferative diabetic retinopathy, 1.49 (95% CI, 0.46-4.89; P = .50) for diabetic macular edema, 2.43 (95% CI, 0.54-11.07; P = .24) for a visually significant cataract, and 4.06 (95% CI, 1.34-12.33; P = .007) for requiring pars plana vitrectomy by 15 years after the diagnosis of diabetes. Diabetic retinopathy, proliferative diabetic retinopathy, and the need for pars plana vitrectomy occurred within a shorter diabetes duration for children with T2D compared with T1D in this population-based cohort. Children with T2D had almost twice the risk of developing retinopathy compared with those with T1D. These findings suggest that to prevent serious ocular complications, children with T2D may require ophthalmoscopic evaluations at least as frequently as or more frequently than children with T1D.

Ophthalmic findings of Mycoplasma-induced rash and mucositis (MIRM) distinct from Stevens-Johnson syndrome

To identify ophthalmic manifestations of Mycoplasma-induced rash and mucositis (MIRM). The medical records of patients with MIRM treated by the inpatient ophthalmology consult service at a single institution over a period of 4 years were reviewed retrospectively. Eye and skin findings, treatment, hospital course, and follow-up findings were documented and reviewed. MIRM was identified in 10 patients, 10-20 years of age (mean, 13.) All presented with oral mucosal findings and a prodrome. On initial examination, conjunctival epithelial defects were present in 2 patients; pseudomembranes, in 3. Five patients experienced progressive ophthalmic manifestations during hospitalization, including a new cornea epithelial defect in 1 patient and a new conjunctival epithelial defect in 3 patients. All were treated with topical steroids and antibiotics. Post-discharge follow-up obtained for 7 patients documented good visual outcomes and lack of significant ocular sequelae without requiring invasive intervention. MIRM, previously referred to as mycoplasma-associated Stevens-Johnson syndrome (SJS) among other names, is now understood to be distinct from SJS in the dermatology community. Our MIRM patients present with mild eye findings and required no surgery, similar to the mild course published in the dermatology literature. Patients with MIRM may have a more benign course than those with SJS.

Clinical parameters and biological markers associated with acute severe ocular complications in Stevens-Johnson syndrome and toxic epidermal necrolysis

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe cutaneous adverse drug reactions with high mortality rates. Its sequelae, such as blindness, persist even after recovery. Patients with SJS/TEN should be accurately diagnosed and receive appropriate treatment as soon as possible. Therefore, identifying the factors for severity prediction is necessary. We aimed to clarify the clinical parameters and biological markers that can predict acute severe ocular complications (SOCs) in SJS/TEN. This retrospective cross-sectional study enrolled 47 patients with SJS/TEN who were divided into two groups according to ocular severity at acute onset: non-severe ocular complications group (n = 27) and severe ocular complications group (n = 20). Multivariate logistic regression analysis revealed that disease severity (body surface area detachment ≥ 10%) was a predictive factor for acute SOCs, and older age (≥ 60 years) was marginally significantly predictive of SOCs. Serum biomarker levels of S100A8/A9 and granulysin were marginally significant and tended to increase in the SOC group. Therefore, during the early acute stage, focusing on disease severity, patient age, and serum inflammatory biomarkers (S100A8/A9 and granulysin) might help predict SOC progression in patients with SJS/TEN who need prompt and aggressive ocular management to prevent severe ocular sequelae.

Computer Vision Syndrome Prevalence and Ocular Sequelae among Medical Students: A University-Wide Study on a Marginalized Visual Security Issue

Introduction: This study aimed to discover and document the potential of visual and ocular sequelae of computer vision syndrome (CVS) among medical students. Methods: This cross-sectional case-control study was conducted on medical students (n=4030) of five universities in Egypt. All students completed a specially designed and validated CVS questionnaire survey (CVS-F3). Students with ≥5 CVS symptoms constituted a risk group (n=352), while students with 1-4 CVS symptoms constituted a low-symptoms group (n=3067). Students from the control and risk groups were examined using objective methods, such as visual acuity, subjective refraction, dry eye disease tests, and anterior segment and fundus examinations. Students who complained of visual blur underwent multifocal electroretinography mfERG examinations (mfERG group). Results: The CVS-F3 indicated that 84.8% of students had complaints that might be related to CVS, however, our ophthalmic examination group revealed only a 56% CVS prevalence rate. The most common single screen type used by 70.4% of students was the smartphone, and the most common complaint was headache (50.2%). Multivariate logistic regression analysis revealed that CVS was significantly associated with increased screen-hours, including &gt;2 screen-hours daily (odds ratio [OR], 2.48; P&lt;0.0001), &gt;2 screen-hours at night (OR, 1.79; P=0.003), and ≥3 screen-years (OR, 1.69; P=0.006). In the mfERG group, 37% demonstrated reduced amplitudes of mfERG rings and quadrants, indicating reduced foveal responses. Conclusion: CVS-questionnaires overestimate the true CVS prevalence and sequelae, which could be accurately detected by objective ophthalmic examination. Smartphones primarily caused CVS among students, with CVS severity increasing in correlation with shorter eye-to-screen distance and frequent use. Contact lens wearing doubled the risk of CVS development and augmented its severity. CVS might affect macular integrity with screen-induced foveal dysfunction.

One severe case of congenital toxoplasmosis in China with good response to azithromycin

BackgroundMost infants infected with Toxoplasma gondii are completely asymptomatic at birth, yet they may develop ocular and neurological sequelae in the first few months of life. Cases of congenital toxoplasmosis with severe jaundice early after birth combined with pancytopenia and splenomegaly are extremely rare. Here, we report on a rare case of congenital toxoplasmosis presenting with severe jaundice and hemolysis early after birth combined with pancytopenia and splenomegaly.Case presentationA male preterm infant with severe jaundice and splenomegaly was admitted to our department. Laboratory examinations revealed severe hyperbilirubinemia, increased reticulocytes, and pancytopenia. After comprehensive analysis and examination, the final diagnosis was congenital toxoplasmosis, and the infant was treated with azithromycin and subsequently trimethoprim-sulfamethoxazole. Regular follow-up revealed congenital toxoplasmosis in both eyes, which was surgically treated, while neurofunctional assessment results were unremarkable. In this case of congenital toxoplasmosis combined with severe jaundice, we treated the infant with two courses of azithromycin, followed by trimethoprim-sulfamethoxazole after the jaundice resolved. Clinical follow-up indicated that this treatment was effective with few side effects; thus, this report may serve as a valuable clinical reference.ConclusionsTimely diagnosis and adequate treatment are closely associated with congenital toxoplasmosis-related prognosis. Infants with congenital toxoplasmosis require long-term follow-up, focusing on nervous system development and ophthalmology.
