Article Synopsis
  • The study evaluates the psychosocial function and health-related quality of life (HRQoL) in Malaysian children with congenital ptosis and assesses the impact of corrective surgery on these aspects.
  • A cohort of 45 children participated, revealing that successful ptosis surgeries led to significant reductions in social anxiety and enhanced HRQoL for both the children and their parents.
  • Factors such as the intereye measurement changes after surgery and the presence of amblyopia played crucial roles in improving social anxiety and HRQoL metrics.

Nutritional optic neuropathy is a rare and often overlooked factor leading to bilateral, symmetrical, and gradual visual impairment. This condition falls within the category of metabolic neuropathies. We documented a case involving bilateral nutritional optic neuropathy attributed to pancytopenia associated with vitamin B12 deficiency.

Purpose Our study aimed to describe the clinical profile of endogenous endophthalmitis, focusing on patient demographics, infection sources, microbial profiles, clinical outcomes, and factors affecting the final visual outcome. Methods A retrospective review was performed on data from 68 eyes of 60 patients diagnosed with endogenous endophthalmitis and hospitalized in two tertiary hospitals on the East Coast of Peninsular Malaysia from January 2011 to December 2020. The analysis encompassed evaluating patient age, gender, laterality, risk factors, infection origins, presenting and final visual acuity, microbial results, treatment responses, and factors affecting final visual outcomes.

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.

Primary non-Hodgkin's lymphoma of the lacrimal sac is extremely rare, usually representing secondary involvement of systemic malignancy. We report a case of bilateral primary non-Hodgkin's lymphoma of the lacrimal sac presenting with bilateral medial canthal swelling for one month which was preceded by a history of chronic bilateral epiphora and a recurrent history of dacryocystitis. The symptoms partially responded to systemic antibiotics for the past three years.

Background: The aim of this paper was to examine the analgesic and anxiolytic effects of binaural beat audio in patients undergoing cataract surgery under topical anaesthesia. Methods: This was a prospective, randomized controlled trial of 61 patients undergoing cataract surgery under topical anaesthesia. They were divided into two research conditions; the binaural beat audio group, and a sham-control group (ear phones with no music).

A healthy 25-year-old gentleman sustained a left eye perforating injury involving a metallic intraocular foreign body. Upon examination, his best-corrected visual acuity was 6/6 in the right eye and 1/60 in the left eye. There was a full thickness cornea-scleral laceration wound with uveal tissue prolapse at 7 o'clock.

An elderly diabetic lady presented with a painful swollen right eye and blurred vision for one week, preceded by right eye redness for six months. Her right eye best-corrected visual acuity was finger counting at 1 m. There was right eye proptosis, limited extraocular muscle movements, corkscrew vessels, chemosis and elevated intraocular pressure, but no bruit.

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.

Functional contributions of individual cellular components of the bone-marrow microenvironment to myelofibrosis (MF) in patients with myeloproliferative neoplasms (MPNs) are incompletely understood. We aimed to generate a comprehensive map of the stroma in MPNs/MFs on a single-cell level in murine models and patient samples. Our analysis revealed two distinct mesenchymal stromal cell (MSC) subsets as pro-fibrotic cells.

The phenotypic instability of adult tissue-derived Schwann cell-like cells (SCLCs) as revealed upon withdrawal of glia-inducing culture supplements limits their clinical utility for cell therapy and disease modelling. We previously overcame this limitation by co-culturing bone marrow-derived SCLCs with neurons purified from developing rat and subsequently human sensory neurons such that direct contact between cell types accomplished the cell-intrinsic switch to the Schwann cell fate. Here, our search for juxtacrine instructive signals found both Notch ligands and neuregulin-1 type III localized on the surface of DRG neurons via live cell immunocytochemistry.

Purpose: To evaluate the efficacy of the "weight, insulin-like growth factor 1, neonatal retinopathy of prematurity" (WINROP) algorithm in predicting retinopathy of prematurity (ROP) requiring treatment in Malaysia.

Participants: This was a retrospective study involving premature infants with gestational age less than 32 weeks treated from September 2016 to March 2019 in Hospital Universiti Sains Malaysia. Clinical diagnosis was made based on Early Treatment Retinopathy of Prematurity study.

Nasolacrimal duct obstruction (NLDO) is the most common cause of childhood epiphora. It is managed conservatively in the first year of life, after which surgical treatment is classically based on a stepwise paradigm of probing, intubation, and dacryocystorhinostomy. This systematic review aims to present the current role of intubation in the management of children with NLDO requiring surgical intervention.

Vitrectomy surgery in proliferative diabetic retinopathy improves the vision-related quality of life. However, there is lack of data on the duration of maintenance of visual gains post vitrectomy. This study thus aimed to determine the survival time of visual gains and the prognostic factors of vision loss after vitrectomy surgery for complications of proliferative diabetic retinopathy.

Optic perineuritis (OPN) involvement in demyelinating disease is rarely encountered. To our knowledge, this is the first reported case of bilateral OPN associated with neuromyelitis optica spectrum disorder (NMOSD). We present a case of a healthy young gentleman who presented with OPN, initially presumed to have a young stroke but later diagnosed to be NMOSD.

Article Synopsis
  • Epilepsy can affect visual functions, with potential changes linked to either the disease or medication side effects.
  • A study was conducted with 100 epilepsy patients on either sodium valproate or carbamazepine, examining visual functions through eye tests.
  • No significant differences in visual function were found between the two medications, but both groups showed color vision defects, suggesting possible early retinal toxicity from the medications.

Background: Health-promoting behaviour is an important concept for health education. Unfortunately, there is a dearth of validated instruments to measure levels of health-promoting behaviour in the Malaysian context. The purpose of this study was to validate a Malay-language version of the Health-Promoting Lifestyle Profile II (HPLP-II) using a confirmatory approach.
