ABSTRACT
Purpose@#Macular edema, serous retinal detachment, and retinal pigment epithelial detachment have been reported in patients with nephrotic syndrome. However, there is limited data about macular thickness in children with nephrotic syndrome. The aim of this study was to compare the mean macular thickness in children with nephrotic syndrome and in a control group and to correlate it with visual acuity and level of proteinuria. @*Methods@#The comparative cross-sectional study included 66 children aged 6 to 17 years with nephrotic syndrome and healthy control seen in two tertiary centers in Malaysia. We recorded demographic data, as well as visual acuity, level of proteinuria, and the mean macular thicknesses in both groups. The mean macular thickness was measured using Stratus optical coherence tomography according to nine areas of the Early Treatment Diabetic Retinopathy Study map. @*Results@#The mean foveal thickness was 238.15 ± 22.98 µm for children with nephrotic syndrome and 237.01 ± 22.60 µm for the control group. There was no significant difference in the mean macular thickness between the groups (p = 0.843). A significant correlation with visual acuity was observed in the superior outer macula (r = –0.41, p = 0.019), the nasal outer macula (r = –0.41, p = 0.019), and the inferior outer macula (r = –0.40, p = 0.021). There was no significant correlation between the mean macular thickness and level of proteinuria (p = 0.338), although those with higher levels of proteinuria demonstrated a trend towards increased macular thickness. @*Conclusions@#The mean macular thickness in children with nephrotic syndrome was similar to that of healthy children. A significant correlation between the mean thickness of the outer macular layer and the presenting visual acuity was observed. There was no correlation between the mean macular thickness and the level of proteinuria.
ABSTRACT
Purpose@#The aim of this study is to determine the mean central corneal thickness (CCT) and mean intraocular pressure (IOP) in children with type 1 diabetes mellitus (T1DM) and to determine the relationship between CCT and IOP on the one hand and age, sex, retinopathy hemoglobin A1c (HbA1c), and duration of diabetes on the other. @*Methods@#This is a case-control, hospital-based study conducted at Hospital Universiti Sains Malaysia between January and November 2022. Thirty-eight children with T1DM were recruited as cases, and 38 healthy children were recruited as controls. The cases and controls then underwent ophthalmic examination, IOP measurement, and CCT measurement using optical coherence tomography (OCT) of the right eye. The IOP measurements were adjusted for CCT for further analysis. @*Results@#The means of CCT and IOP values were significantly higher in the T1DM group than in the control group (all p = 0.02). The mean CCT was 542.18 ± 20.40 μm in the T1DM group, and 529.52 ± 26.17 μm in the control group. The mean IOP was 14.68 ± 1.98 mmHg in the T1DM group, and 13.52 ± 1.66 mmHg in the control group. The mean HbA1c was 10.68% ± 2.49% in the T1DM group. Age and duration of DM were found to have a significant association with CCT in children with T1DM. The duration of DM was also found to be significantly associated with the IOP. Sex and HbA1c levels were found to have no significant relationship with either CCT or IOP. @*Conclusions@#Children with T1DM have significantly higher CCT and IOP than the average child. The duration of DM is a significant factor that impacts both CCT and IOP. In addition, age is another factor that affects CCT in children with T1DM.
ABSTRACT
Purpose@#The prevalence of retinopathy of prematurity (ROP) is higher in developing countries compared to developed countries. There is limited data on vision-related quality of life (VRQoL) among children with severe type of ROP in developing countries. This study evaluated the influence of threshold and prethreshold ROP on VRQoL in Malaysian children. @*Methods@#Multicenter prospective cross-sectional study conducted in three tertiary hospitals in 2018 to 2019. Children less than 7 years old with previous ROP diagnosis were recruited. Patients with systemic comorbidities that affected vision or daily activities were excluded. A parent or guardian completed the Children’s Visual Function Questionnaire (CVFQ) for the assessment of child’s general health, general vision, competence, personality, family impact, and treatment difficulty. @*Results@#Eight were categorized with threshold ROP, 16 with high-risk prethreshold ROP, and 26 with low-risk prethreshold ROP. Fifty age-matched controls were also included. Mean visual acuity in logarithm of the minimum angle of resolution was 0.46 in the threshold, 0.08 in high-risk prethreshold, and 0.01 in low-risk prethreshold subgroups. Threshold ROP was associated with myopia and strabismus, and associated with poor visual acuity compared to prethreshold ROP. Mean total CVFQ score was significantly lower in the ROP group (p < 0.001) compared to the control group. Mean score and all mean subscale scores were significantly lower in the threshold subgroup compared to high-risk and low-risk prethreshold subgroups, with lowest subscale scores on general vision and general health. There was significant association between gestational age, visual acuity of the better eye, family income, and VRQoL (p < 0.05). @*Conclusions@#ROP was associated with lower VRQoL in children born prematurely in Malaysia. The threshold ROP group is the most affected. General vision and health domains are their main difficulties encountered. Gestational age, visual acuity of the better eye, and family income affects the VRQoL.
ABSTRACT
Purpose@#There are limited data from Asian countries regarding retinal thickness in children with type 1 diabetes mellitus (T1DM). This study aimed to compare the macular and retinal nerve fiber layer (RNFL) parameters between diabetic children without retinopathy and non-diabetic healthy children. We also evaluated the factors associated with RNFL thickness in children with T1DM. @*Methods@#A comparative cross-sectional study was conducted among children with T1DM and healthy children aged 7 to 17 years old in Hospital Universiti Sains Malaysia from 2017 to 2019. Children with retinal disease or glaucoma were excluded. Macular and RNFL thicknesses were measured using spectral-domain optical coherence tomography. Demographic information, duration of diabetes, blood pressure, body mass index, visual acuity, and retinal examination findings were documented. Glycosylated hemoglobin levels, renal function, and blood lipid levels were also collected. @*Results@#Forty-one children with T1DM and 80 age- and sex-matched children were enrolled. Both sexes were affected. Mean duration of diabetes mellitus was 3.66 years. The mean glycated hemoglobin levels in the T1DM group was 9.99%. The mean macular and RNFL thicknesses in children with T1DM were 277.56 (15.82) µm and 98.85 (12.05) µm, respectively. Children with T1DM had a significantly thinner average macula, superior outer macula, nasal outer macula, mean RNFL, and inferior RNFL thickness compared to controls (p < 0.05). There was a significant association between nephropathy and the mean RNFL thickness. @*Conclusions@#Children with T1DM had significantly decreased mean macular and RNFL thicknesses. Nephropathy is associated with an increased RNFL thickness.

ABSTRACT
@#Introduction: Oral health status among visually impaired (VI) children have shown to be poorer when compared with their normal peers. This preliminary study aimed to determine the oral health status of VI children and knowledge, attitudes and practices of their caregivers. Methods: A preliminary, cross sectional study were conducted on VI children and their caregivers attending Ophthalmology clinic Hospital USM. The assessment of oral hygiene was done using Sillness-Loe plaque index and dental caries using DMFT/dft index. Self-administered, validated questionnaires on knowledge, attitudes and practice towards a child’s oral health was distributed to the caregivers. Results: A total of 27 VI children along with their caregivers participated in this study. The mean age of VI children and their caregivers was 11.4(3.05) and 41.7(7.10) respectively. The children showed a fair oral hygiene status. The median(IQR) for caries experience for deciduous teeth (dft) and permanent teeth (DMFT) was 0.0(5.00) and 1.0(4.00) respectively. Caries prevalence among VI children was high at 85.2% (95% CI:70.86% - 99.51%). The caregivers showed a relatively good attitude and practice towards their child’s oral health with mean(SD) score of 23.2(2.95) out of 28 and 12.8(2.15) out of 19 respectively in comparison to low oral health knowledge of 5.5(1.50) out of 11. Conclusion: The oral hygiene status was fair with high prevalence of dental caries. Based on the score, although the caregivers showed to have minimal understanding on children’s oral health, their attitude and practice towards children’s oral health are relatively high.
ABSTRACT
@#Introduction: Limited information is available on healthrelated quality of life (HRQoL) in children with strabismus in South East Asia. We aimed to evaluate the HRQoL and associated factors pre- and post-strabismus surgery in Malaysian children with infantile esotropia and their parents/guardians. Methods: A prospective study was conducted on children with infantile esotropia aged 8-17 years old and their parents/guardians who attended two tertiary hospitals with a paediatric ophthalmology service from 2017 to 2018. The patients and parents answered the Intermittent Exotropia Questionnaire (IXTQ), translated into Malay, at the time of enrolment and three months after the surgery. Results: Thirty-four children and one (each) of their parents/guardians were enrolled. Thirteen (38.2%) children had esotropia with angles of deviation of more than 50 prism dioptres. A total of 33 (97.1%) children achieved successful alignment correction three months after surgery. Surgery significantly improved the total mean scores of the children, which were 62.87 (17.05) preoperatively and 87.13 (13.26) postoperatively (p<0.001). There was statistically improvement in the total mean scores in the parent/guardian group, which was 37.07 (22.01) preoperatively and 75.39 (22.09) postoperatively (p<0.001). The parents/guardians functional, psychosocial and surgery subscales also had a significant increment in the score postoperatively (p<0.001). Older children and children with poorer visual acuity on presentation had a lower score preoperatively, while girls scored better postoperatively (p<0.05). Mothers scored significantly lower preoperatively and postoperatively (p<0.05). Conclusion: Surgery significantly improved the HRQoL score in Malaysian children with infantile esotropia and their parents/guardians. The score was significantly higher in female children after the surgery. Mothers exhibited poor scores before and after surgery
ABSTRACT
INTRODUCTION@#Limited data is available on paediatric orbital cellulitis in Asia. We aimed to describe demographic data, clinical presentation, predisposing factors, identified microorganisms, choice of antibiotics and management in children with orbital cellulitis treated in a tertiary care centre in Malaysia.@*METHODS@#A retrospective review was performed on children with orbital cellulitis aged below 18 years who were admitted to Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2013 and December 2017.@*RESULTS@#A total of 14 paediatric patients fulfilling the diagnostic criteria for orbital cellulitis were included. Their mean age was 6.5 ± 1.2 years. Boys were more likely to have orbital cellulitis than girls (71.4% vs. 28.6%). Involvement of both eyes was observed in 14.3% of the patients. Sinusitis (28.6%) and upper respiratory tract infection (21.4%) were the most common predisposing causes. Staphylococcus aureus (28.6%) was the leading pathogen. Longer duration of hospitalisation was observed in those infected with methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei. 10 (71.4%) patients were treated with a combination of two or three antibiotics. In this series, 42.9% had surgical interventions.@*CONCLUSION@#Young boys were found to be more commonly affected by orbital cellulitis than young girls. Staphylococcus aureus was the most common isolated microorganism. Methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei caused severe infection. Sinusitis and upper respiratory tract infection were the most common predisposing factors. A majority of the children improved with medical treatment alone. Our findings are in slight disagreement with other published reports on paediatric orbital cellulitis, especially from the Asian region.
ABSTRACT
<p><b>INTRODUCTION</b>Available data on traumatic cataract in Asian children is primarily confined to South Asian countries. We aimed to describe the demographics, nature of injury and visual outcomes of Malaysian children with traumatic cataract from a suburban area, and discuss the literature on Asian children with this condition.</p><p><b>METHODS</b>We conducted a retrospective study of 29 children below 17 years of age who were diagnosed with traumatic paediatric cataract and who attended Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2000 and December 2010. Follow-up periods ranged from 12 to 120 months. Demographic data, clinical features, mechanism and extent of injury, and final visual outcome were recorded.</p><p><b>RESULTS</b>The study population was predominantly male. The right eye was injured in 62.07% of patients. A majority of patients had penetrating injuries, with the most common cause being injury by an organic foreign body (24.14%). Presenting visual acuity worse than 6/60 was observed in 68.97% of patients. Only 34.48% of patients had a final corrected visual acuity of 6/12 and better. 55.18% of patients were operated on within less than one month of their injuries. A majority of children sustained concurrent injuries to the anterior segment structures. Corneal opacity and amblyopia were the most common causes of poor final visual acuity.</p><p><b>CONCLUSION</b>Health education and awareness are essential tools that can prevent avoidable blindness due to traumatic cataract in the paediatric population. The importance of rehabilitation programmes for these patients should be emphasised.</p>

RetCam is an excellent screening tool for the detection of retinopathy of prematurity (ROP). However, affordability is a barrier when adopting the use of RetCam in developing countries. We aimed to describe different stages of ROP using ultrasonographic B-scan and to evaluate the association between funduscopic examinations and ultrasonographic B-scan findings in premature neonates with ROP in Malaysia. A descriptive cross sectional study was conducted in 90 eyes of 47 premature neonates with different stages of ROP in three tertiary hospitals in Malaysia. Experienced ophthalmologists performed detailed funduscopic examinations using binocular indirect ophthalmoscopy (BIO). A masked examiner performed a 10 MHz ultrasonographic B-scan evaluation with 12 meridian position images within 48 hours of clinical diagnosis. Data from the clinical examination and ultrasonographic findings were collected and analysed. We recruited 37 eyes (41.1%) with stage 1 ROP, 29 eyes (32.3%) with stage 2, 18 eyes (20.0%) with stage 3, and 3 eyes (3.3%) with stages 4 and 5 based on the clinical assessment. Ultrasonography correctly identified 3 (8.1%) stage 1 eyes, 17 (58.6%) stage 2 eyes, 13 (72.2%) stage 3 eyes, and 3 each (100%) of the stage 4 and 5 eyes. There was a significant association between the funduscopic signs and the ultrasound findings for stage 2 ROP and above (Fisher’s exact test, p <0.001). In conclusion, all stages of ROP were detected and described with a 10 MHz ultrasonic B-scan system. A significant association was observed between funduscopic signs and ultrasonographic findings in premature Malaysian neonates with stage 2 ROP and above.
ABSTRACT
Although few studies concerning optic neuritis (ON) in Asian countries have been reported, there is no report about ON in Malaysia particularly within the Malay population. We aimed to determine the clinical manifestation, visual outcome and aetiology of ON in Malays, and discussed the literature of ON studies in other Asian populations. This was a retrospective study involving 31 consecutive patients (41 eyes) with ON treated at Hospital Universiti Sains Malaysia commencing from July 2005 till January 2010 with a period of follow-up ranging from 18-60 months. The clinical features, laboratory results, possible aetiology, and visual acuity after one year were analysed. Females were the predominant group. The age of the patients ranged between 3-55 years and peaked between 21-30 years old. 67.7% of the patients had unilateral involvement. Pain on ocular movement was observed in 31.7% of the affected eyes. 73.3% of 41 involved eyes showed visual acuity equal 6/60 or worse on presentation. Paracentral scotoma was the most common visual field defect noted. Optic disc papillitis proved more widespread compared to the retrobulbar type of ON. The aetiology was idiopathic in more than 50%, while the risk of multiple sclerosis was extremely low (3.2%) in our series. 66.0% demonstrating visual acuity improved to 6/12 or better at one year after the attack. 16.1% showed evidence of recurrence during follow-up. In conclusion, the clinical profile and aetiology of ON in Malay patients are comparable to other ON studies reported by other Asian countries.
ABSTRACT
Rhino-orbito-cerebral mucormycosis is a fungal infection that can be fatal especially in immunocompromised patients. It is extremely rare in immunocompetent individuals. We describe here an immunocompetent patient who survived rhino-orbito-cerebral mucormycosis due to Saksenaea vasiformis, and provide a literature review of this rare entity
ABSTRACT
A 21-year-old and an 11-year-old patients presented with severe,resistant shield ulcers failed to respond to medical treatments which included topical steroids,mast cell stabilizers and antihistamines. Both of them were treated with surgical debridement of the ulcer,supratarsal injection of triamcinolone acetonide,topical cyclosporine 0.5g/L and ketotifen fumerate 0.25g/L. The ulcers healed well after three weeks. Topical cyclosporine was discontinued after two months in both patients. They were symptom free with no recurrence for six months. Combination of surgical debridement of the ulcer,supratarsal injection of triamcinolone acetonide,topical cyclosporine 0.5g/L and ketotifen fumerate 0.25g/L are effective as the treatment option in managing patients with severe vernal shield ulcer.KEYWORDS: vernal shield ulcer; surgical debridement; supratarsal injection of triamcinolone acetonide; cyclosporine; ketotifen fumerate
