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.

Altitudinal visual field defect is a rare presentation of retrochiasmal lesion especially when bilateral visual fields were affected. In fact, bilateral inferior altitudinal visual field defect (BIAVFD) usually occurred in patients who survived a gunshot injury to the occipital lobe or as a direct trauma to the brain. We report a rare case of BIAVFD secondary to occipital meningioma. A high index of suspicion enables timely investigation and diagnosis when dealing with atypical presentation of intracranial meningioma.

Background Fungal keratitis is one of the commonest causes of corneal blindness in developing countries including Malaysia. We aim to evaluate the sociodemographic background, clinical features, predisposing factors, laboratory findings, management, complications, and visual outcome of patients with fungal keratitis in a tertiary hospital in Malaysia. Methods A retrospective review of medical and microbiology records of all patients treated for corneal ulcer from 2015 to 2019 at Hospital Sultanah Bahiyah was performed. Sociodemography, predisposing risk factors, clinical characteristics, causative organisms, and final visual outcome were analyzed. Results We identified 103 patients with a diagnosis of fungal keratitis. The majority of the patients were of Malay ethnicity (85.4%) and male gender (81.6%), with an age range of 21 to 60 years (94.1%). Ocular trauma was the main predisposing factor in 82 (79.6%) patients. Poor visual improvement was observed in groups with ulcer more than 4mm (67.5%), presence of hypopyon (50.9%), and high intraocular pressure (75.0%) upon presentation. Fusarium spp. (19.4%) was the commonest fungus isolated followed by Aspergillus spp. (5.8%). All patients were prescribed either topical, oral, intracameral, or combined therapy, whereas 20 (19.4%) patients required surgical intervention, of which 16 (15.5%) underwent penetrating keratoplasty and three (2.9%) required evisceration. Conclusion The epidemiological, socioeconomic, and predisposing factors may facilitate timely diagnosis and prompt treatment to achieve a better visual outcome and minimize complications including corneal blindness.

BACKGROUND: This study was conducted with the objective to examine demographic statistics and histopathological diagnoses of orbital biopsies from cases referred to the Oculoplastic subspecialty of the Ophthalmology department in Hospital Sultanah Bahiyah, Kedah, from 2016 to 2020.
METHOD: This study is a case series of 28 patients who underwent orbital biopsy.
RESULT: A total of 34 orbital biopsies from 28 patients were recorded. The mean age was 48.3 ± 19.1 years old. 22 (78.4%) cases manifested unilaterally and six (21.4%) manifested bilaterally. The commonest presentations were orbital mass (36.6%) and proptosis (24.4%). The mean duration of the presentation was 16.2 ± 19.5 months. Fourteen (50.0%) patients underwent orbital biopsy within six months of symptoms. 52.8% of the tumours are situated at supero-temporal region of the orbit. 53.0% (18) situated in extraconal space of orbit. Out of all, 23 (67.6%) cases were benign and 11 (32.4%) cases were malignant. All were primary in origin (100%). The commonest orbital tumours reported were malignant lymphoma (29.4%), reactive lymphoid hyperplasia (14.7%), non-caseating granulomatous inflammation (11.8%), non-granulomatous inflammation (5.9%) and cavernous haemangioma (5.9%). Of all 10 malignant lymphomas from eight patients (two were bilateral eyes) were all mucosa-associated lymphoid tissue (MALT) of primary non-Hodgkin lymphomas. None of the cases were reported to be metastasis from the systemic spread. The majority of patients' eyes (20, 58.8%) remained the same visual acuity post-biopsy while six (17.6%) eyes had improvement in visual acuity and eight (23.5%) eyes had reduced postoperative visual acuity.
CONCLUSION: Malignant tumours are more common in the elder age group especially malignant lymphoma which is in contrast to Caucasian populations. Understanding the relative incidence of these various orbital tumours is essential to patient evaluation and management.

Hearing loss is rarely associated with sympathetic ophthalmia. We describe a young man who presented with sympathetic ophthalmia and concurrent hearing loss one month post globe rupture. The presentation was very subtle and atypical. However, the patient recovered fully after two weeks of prompt oral corticosteroid therapy which resulted in good visual and hearing outcomes. This patient demonstrated that the acute phase of sympathetic ophthalmia is reversible with early recognition of features, timely diagnosis, and rapid initiation of corticosteroid therapy.

Background The majority of eyelid tumours are benign in nature and constitute 82%-98% of all eyelid tumours. This study aimed to explore the prevalence and frequency of histopathological diagnoses of eyelid tumours encountered in Hospital Sultanah Bahiyah (HSB), Malaysia, from 2016 to 2020. Method This study is a case series of 136 patients with eyelid tumours who underwent eyelid biopsy. Result Twenty-three (17%) patients were below 18 years old, 64 (47%) patients were between 19 and 64 years old and 49 (36%) patients were more than 65 years old. The mean age in this study was 47.9 ± 25.4 years. The most common benign eyelid tumours were dermoid cyst (31, 22.8%), melanocytic nevus (19, 14%), granuloma (17, 12.5%), squamous cell papilloma (13, 9.6%) and epidermal cyst (12, 8.8%). Most of the benign eyelid tumours occurred at the upper lids (79.8%), and most of the malignant eyelid tumours occurred at the lower lids (81.8%). The most common malignant eyelid tumours were basal cell carcinoma (BCC) (6, 14.3%), followed by malignant lymphoma (3, 6.1%) and sebaceous gland carcinoma (2, 4.1%). Eight out of nine cases of BCC were located at the lower lids. All malignant lymphomas were primary lymphoma. Five were extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT), and one was follicular lymphoma. All cases with benign and malignant tumours required only a single surgery for excision, and none of the cases had a recurrence. Conclusion There were limited references to the epidemiology of histopathological diagnoses of eyelid tumours in Malaysia. Although benign lesions comprise the majority of eyelid tumours, it is essential to delineate between benign and malignant eyelid tumours.

Introduction Ocular syphilis is a sight-threatening condition. It can occur at any stage of syphilis infection, which present either with acute inflammation during the primary, secondary, and early latent stages or with chronic inflammation during tertiary infection, affecting virtually every ocular structure. This study was to report on the clinical presentation of ocular syphilis that presented to eye clinic Hospital Universiti Sains Malaysia. Methodology This was a retrospective study where medical records of ocular syphilis patients who attended eye clinic in Hospital Universiti Sains Malaysia from January 2013 to June 2017 were reviewed. Results A total of 10 patients (13 eyes) with ocular syphilis were identified out of 106 cases that presented with ocular inflammation. The mean age of presentation was 69.8 ± 6.4 years and seven of them (70%) were female. All patients were Malay and human immunodeficiency virus (HIV) was negative. The ocular manifestations included panuveitis (four eyes, 30.8%), anterior uveitis (two eyes, 15.4%), posterior uveitis (seven eyes, 53.8%) and optic neuritis (two eyes, 15.4%). Seven (53.8%) eyes presented with visual acuity of worse than 6/60, five (38.5%) eyes had visual acuity between 6/15 to 6/60, and one (7.7%) eye had visual acuity of 6/12 or better. Nine patients received an intravenous benzylpenicillin regime and one patient received an intramuscular penicillin injection. Out of 13 eyes affected, 11 (84.6%) eyes had improved visual acuity of at least one Snellen line after treatment. Visual acuity of 6/12 or better increased to four (30.8%) eyes. Conclusions Posterior uveitis was the commonest presentation of ocular syphilis in HIV-negative patients. Early detection and treatment of ocular syphilis can result in resolution of inflammation and improvement of vision.
