AI-Based Method for Detecting Retinal Haemorrhage in Eyes with Malarial Retinopathy

Some form of ophthalmic injury is seen in the majority of lightening victims. These may be anterior segment involvement, mostly the cornea. Other lesion on the anterior segment include uveitis, hyphaema, cataract and dislocated lens. Posterior segment lesion include vitreous haemorrhage, retinal oedema, retinal haemorrhage, retinal detachment, cystoids macular oedema, chorioretinalrupture, maculopathy, CRVO and CRAO. Neuro-ophthalmic lesion include loss of pupillaryreflex, anisocoria, horner syndrome, multiple cranial nerve palsies and nystagmus.

Abstract Purpose This study aimed to determine the proportion and types of ocular abnormalities detected in healthy term newborns and also the risk factors associated with retinal haemorrhages. Method This cross-sectional study comprised of 203 participants, all healthy term newborn infants in the Obstetrics and Gynaecology ward at Hospital Kuala Lumpur over a six months period. The examination list includes external eye examination, red reflex test, and fundus imaging using a wide-field digital retinal imaging system (Phoenix Clinical ICON Paediatric Retinal Camera) by a trained Investigator. The pathologies detected were documented. The results were compared with similar studies previously published in the literature. Results Total ocular abnormalities were detected in 34% infants. The most common finding was retinal haemorrhage in 29.6% infants, of which 53.3% occurred bilaterally. Spontaneous vaginal delivery (SVD) remained the greatest risk factor which has nearly four times higher risk of newborns developing retinal haemorrhage compared to Lower Segment Caesarean Section (LSCS). There was a 6% increased likelihood of developing retinal haemorrhage for every 1 minute increment in the duration of 2nd stage of labour. Newborns delivered via SVD with episiotomy had 2.5 higher odds of developing retinal haemorrhage in newborns compared to SVD without episiotomy. Conclusion Universal eye screening for all newborns using a wide-field digital imaging system is possible, safe and useful in detecting posterior segment disorders. The most common abnormality detected is retinal haemorrhage. Although most resolve spontaneously, a longitudinal study is needed to study the long term effect of retinal haemorrhages in these infants.

Background: In malaria endemic areas diagnosis of severe malaria by microscopy and immunodiagnostic test is confounded by asymptomatic peripheral blood parasitemia. In such settings, retinal changes by ophthalmoscopy showed some diagnostic utility. Contribution of ophthalmoscopy in diagnosis of severe malaria in children is not well studied in Bangladesh. The aim of this study was to describe the retinal findings in children of cerebral and non-cerebral severe malaria by direct and indirect ophthalmoscope and relate their outcome and to determine the course of changes in the fundus. Methodology: In this prospective observational study 130 consecutive children aged between 6 months to 12 years admitted with confirmed severe Plasmodium falciparum malaria in pediatrics ward of Chittagong Medical College Hospital, Chittagong, Bangladesh were assessed by both direct and indirect ophthalmoscopy during the period of April 2008 to March 2009. Results: Out of 130 patients 80 children had cerebral malaria and of these 49 (61.2%) had some degree of retinopathy; 24 (48%) of 50 with non cerebral severe malaria had retinopathy. Predominant retinal changes were Retinal hemorrhage and Macular whitening each in 53 (40.77%) patients, followed by peripheral whitening, Vessels changes and papilloedema in 50 (38.46%), 40 (30.77%) and 14 (10.78%) patients respectively. With indirect ophthalmoscope as reference, direct ophthalmoscopy had a high sensitivity to detect macular whitening, and papilloedema but was less sensitive to detect peripheral whitening and vessel changes. Patients with retinopathy had more chance to had unfavorable outcome (Death) in comparison to the patients who had not {Odds ratio:1.09 (95% CI:1.017-1.167)}. Most of these retinal changes were transient and resolved gradually as clinical condition improved. Conclusion:Features compatible with malarial retinopathy were commonly found in our children with severe malaria. Ophthalmoscopy is an important clinical tool to aid in diagnosis and prognosis in children. However, indirect ophthalmoscopy provides better information than direct ophthalmoscopy.

Outcome Score

AimTo report disability and visual outcomes following suspected abusive head trauma (AHT) in children under 2 years.MethodsWe present a retrospective case series (1995–2017) of children with suspected AHT aged ≤24 months. King’s Outcome Score of Childhood Head Injury (KOSCHI) was used to assess disability outcomes at hospital discharge and at follow-up. The study used a retinal haemorrhage score (RHS) to record findings at presentation and a visual outcome score at follow-up.ResultsWe included 44 children (median age 16 weeks). At presentation, 98% had a subdural haemorrhage and 93% had a retinal haemorrhage. At discharge, 61% had moderate-to-severe disability, and 34% a good recovery. A higher RHS was observed in those with more disability (r=−0.54, p=0.0002). At follow-up, 14% had a worse KOSCHI score (p=0.055). 35% children had visual impairment, including 9% with no functional vision. Those with poorer visual function had a higher RHS (r=0.53, p=0.003). 28% attended mainstream school without support; 50% were in foster care or had been adopted, 32% lived with birth mother and 18% with extended family.ConclusionIt is known that injuries from suspected AHT result in high levels of morbidity; our cohort showed significant rates of disability and visual impairment. Those with higher disability at discharge and poorer visual function showed more significant retinal changes. The extent of disability was not always apparent at hospital discharge, impacting on provision of prognostic information and targeted follow-up.
