    We present a case of a 45-year-old female who presented with blurring of right vision associated with constitutional symptoms. Examinations revealed right optic disc swelling with inferior exudative retinal detachment and hepatomegaly. Gynaecological examination showed a fungating cervical mass. Histopathological reports of cone biopsy confirmed the presence of large B cell non-Hodgkin lymphoma. HIV screening was positive. A diagnosis of HIV related lymphoma was made. Chemotherapy and antiretroviral treatment were instituted. The ocular signs resolved. However, the patient could not tolerate the side effects of medical therapy and opted for palliative treatment.

    This survey represents an initial examination of contact lens practice in Malaysia. It is based on a questionnaire that was sent to selected members of the Association of the Malaysian Optometrists to survey the prescribing habits of g contact lenses and care products. Questions included types of lenses prescribed, care systems frequently recommended and types of complications seen. Optometrists in Malaysia prescribed an average of 90 new pairs of contact lenses per year. Soft lenses made up 84% of the prescription followed by 14% of rigid gas permeable lenses and 1.5% of polymethymethacrylate lenses. Disposable/frequent replacement lenses accounted for 60% of the soft lenses prescribed. The most commonly prescribed disinfecting system was chemical disinfection. The most common complication seen during aftercare consultation was dry eye-related problems.

    A 50-year-old Chinese man presented with sudden onset of painful right eye, diplopia, and redness associated with headache and deteriorating vision. Examination revealed obvious proptosis with elevated intraocular pressure. Computed tomography (CT) scan showed presence of retrobulbar haemmorhage. Emergency lateral canthotomy and cantholysis was performed followed by medical orbital decompression, resulting in improvements in visual acuity, and other ocular symptoms. The diagnosis of thrombosed orbital varices involving inferior ophthalmic vein was confirmed on radiological- angiographic study. To date, he is symptoms-free with good visual acuity. Immediate surgical decompression with lateral cantholysis for retrobulbar haemorrhage was effective in the treatment of retrobulbar haemorrhage.

    This was a case of a young lady presenting with 10 year history of a mass in the right eye. It was found to be an adenocarcinoma of the lacrimal gland from histopathological biopsy. She underwent wide excision, orbital exenteration and reconstruction with a free rectus abdominis flap. Unfortunately, she had a tumour recurrence which was not controlled by radiotherapy and a second excision. The behavior of the tumour was aggressive, resulting in widespread metastases. She passed away within a year of her presentation. Of note, the histopathology report from the second excision turned out to be sarcomatoid carcinoma. This is described in the literature as dedifferentiation, or high grade transformation (HGT). Occurrence of dedifferentiation in salivary gland tumours is well-established, but not as well-described in lacrimal gland tumours. In this case, there was a severely delayed presentation of a lacrimal gland adenocarcinoma in a young person, which underwent dedifferentiation into a sarcomatoid carcinoma. This phenomena is associated with aggressive tumour biology behavior and poor prognosis, despite surgery and radiotherapy.

    Acanthamoeba is a free-living protozoa which causes serious ocular problem. Acanthamoeba keratitis is becoming more prevalent amongst contact lens wearers and it can cause loss of vision and blindness if not treated properly. The objective of this research is to determine the effectiveness of gentamicin against six Acanthamoeba spp. isolates, of which three were clinical isolates (HS 6, HKL 95, HTH 73) and three environmental isolates (SMAL 7, SMAL 8, TTT 9). Cyst suspension from the chosen isolates were exposed to gentamicin. After 48 hours of incubation at temperature of 30°C and 37oC, each mixture was filtered and filtration membrane was put onto non-nutrient agar laid with Escherichia coli. The agar plates were incubated for three days at 30oC and 37oC and the plates were examined daily until day 14 to look for the presence of Acanthamoeba trophozoites under inverted microscope. The presence of trophozoites indicated the ineffectiveness of gentamicin. Gentamicin was found to be effective against Acanthamoeba cysts from all the test strains at both incubation temperatures. The minimum cysticidal concentration (MCC) mean value of gentamicin was 0.193 mg/mL at 30oC and 0.229 mg/mL at 37oC. So, we concluded that gentamicin has cysticidal potential towards Acanthamoeba.

    We describe the first clinical case of contact lens related corneal ulcer caused by Elizabethkingia meningosepticaregistered in Southeast Asia. A 20-year-old female student who wasa regular soft contact lens wearer, presented with pain, photophobia and blurring of vision of the right eye for 3 days. On slit lamp examination, there was a small paracentral anterior stromal infiltrate with an overlying epithelial defect. Microbiological cultures from corneal scrapings, contact lens and its casing were positive for E.meningoseptica. Due to high likelihood of contact lens contamination causing keratitis, topical fortified gentamicin0.9% and ceftazidime 5% were administered empirically. Topical vancomycin 5% was later added tailoring to the culture and sensitivity of the organism. After 8 weeks of treatment, the keratitis subsided and corneal epithelial defect completely healed with residual corneal opacity. Even though uncommon, contact lens related E.meningosepticakeratitis can occur in healthy immunocompetent individuals with no ocular comorbidities.

    BACKGROUND: Cataract surgery is associated with a variety of complications, one of which is vitreous loss. Doctors and policymakers should be aware about the precipitating factors, associations, and expected outcomes of vitreous loss. This study was, therefore, undertaken to set guidelines to improve the visual outcomes of patients.

    MATERIALS AND METHODS: A retrospective 8-year analysis was conducted from 2007 to 2014 using the national eye database. Demographic features, ocular comorbidities, grade of surgeon, type of surgery, and the associations with the occurrence of vitreous loss, and the final visual outcomes of these patients were studied.

    RESULTS: Out of 12,992 eyes, only 3.2% had vitreous loss, mostly aged <40 years. Pseudoexfoliation was the only ocular comorbidity causing vitreous loss. Medical Officers and Gazetting Specialists got more vitreous loss compared to specialists. Intracapsular cataract extraction, phaco convert to extracapsular cataract extraction (ECCE), ECCE, and phaco all had a significant vitreous loss. Vitreous loss was the most significant intraoperative complication causing poor vision and resulted in impaired or poor visual outcome.

    CONCLUSION: Vitreous loss occurred in almost all types of cataract surgeries, especially by junior surgeons, among those aged <40 years and significantly caused poor visual outcome compared to other complications. Pseudoexfoliation had higher occurrence of vitreous loss. Vitreous loss patients had impaired/poor visual outcome due to preexisting comorbidity and astigmatism. Patients at risk and junior surgeons should be closely monitored to improve outcomes. Further studies need to be done to see why and when the vitreous loss occurred.

    Trauma is a common problem in Cownose Ray during mating season in both wild and captive rays. Enucleation is indicated when there is an ocular trauma. A 5-year-old female Cownose Ray (Rhinoptera bonasus) from Aquaria of Kuala Lumpur Convention Centre (KLCC) was presented to University Veterinary Hospital (UVH), Universiti Putra Malaysia, with a complaint of protruding left eye, which resulted from crushing into artificial coral during mating season. There were a hyphema in the traumatic left eye, periorbital tissue tear, exposed left eye socket, and multiple abrasions on both pectoral fins. The Cownose was anaesthetized and maintained with isoeugenol and on-field emergency enucleation of the left eye was performed. It was managed medically with postoperative enrofloxacin, tobramycin ointment, and povidone iodine. No suture breakdown and secondary infection were observed at day 7 after enucleation during revisit. At day 24 after enucleation, the Cownose responded well to treatment with excellent healing progression and no surgical complication was observed.

    Myasthenia gravis (MG) is a rare autoimmune disorder
    characterised by fluctuating and variable combination
    of muscle weakness and fatigue. Most cases are due to
    T-cell mediated autoantibodies against post-synaptic
    acetylcholine receptors (AChR-Ab), thus preventing
    acetylcholine from binding and signalling skeletal
    muscle to contract.1
    The annual incidence is 7-23 new cases per million.1
    It can occur at any age but with two peaks; an earlyonset
    (20-40 years) female-predominant and a late-onset
    (60-80 years) male-predominant peak. MG is classified
    into ocular and generalised (80%). More than half the
    patients initially present with ptosis and diplopia but half
    will progress to generalised disease with involvement of
    bulbar, limb and respiratory weakness. Those presenting
    as generalised MG can also develop eye signs later.1
    It is important to recognise MG early because it is
    highly treatable. Untreated disease leads to permanent
    weakness.2 Treatment reduces mortality from lifethreatening
    myasthenic crisis.1,3 Misdiagnosis leads to
    potentially harmful interventions and inappropriate
    management.4,5 Diagnosis in late-onset MG is easily
    missed2,3,4,5 because of overlapping symptoms with
    other diseases common in the elderly. We report a case
    of delay and misdiagnosis in an elderly patient with
    co-morbidities. (Copied from article).

    Hypervirulent Klebsiella pneumoniae strain is a major cause of liver abscess and this bacteria has metastatic properties. This distinct liver abscess syndrome has been increasingly reported in Asia over the past two decades, but is emerging as a global disease. We described an 81-year-old lady, who presented to the emergency department with 1-week prior duration of fever and right eye swelling. She had been admitted for recurrent liver abscess prior to this. Hence, she was initially treated as sepsis secondary to recurrent liver abscess. Meanwhile, she was managed concurrently by ophthalmology team for endophtalmitis. Despite the initiation of treatment with antibiotics, she did not show any improvement and required right eye evisceration to treat the sepsis. Invasive liver abscess syndrome with metastatic endophthalmitis should be screened in patient with Klebsiella liver abscess. They should be monitored for ocular symptoms as early recognition can prohibit delays in treatment, which has debilitating consequences.

    Olopatadine HCl is an antiallergic drug used for the management of allergic conjunctivitis. Currently, it is delivered via eye drop solution, which is highly inefficient due to low bioavailability. Silicone contact lenses can be used to sustain the release of ophthalmic drugs. However, the presence of drug alters the optical transmittance and physical properties of the contact lens. The objective was to design a novel polyvinyl pyrrolidone (PVP)-coated olopatadine-ethyl cellulose microparticles-laden doughnut contact lens to sustained ocular delivery with limited alteration to the optical and swelling properties of the contact lens. The doughnut was implanted within the periphery of the lens using modified casting technique. Olopatadine HCl was loaded by soaking (SM-OL), direct loading (DL-OL), and doughnut casting method (DNT-OL). PVP (comfort agent) was loaded on the surface of contact lens for all the batches via novel curing technique. The in vitro olopatadine HCl release data of SM-OL (up to 48-72 h) and DL-OL batches (up to 72 h) showed high burst release, whereas DNT-OL batch showed sustained release up to 120 h without significant (p > 0.05) alteration in the optical and swelling properties of contact lens. All the batches showed sustained release of PVP up to 120 h. The in vivo studies in the rabbit tear fluid showed improvement in the olopatadine HCl and PVP retention time in comparison to eye drop solution. The PVP-loaded DNT-OL-500 lens showed tear stabilization (comfort wear) in Schirmer strip test (rabbits) with no protein adherence in comparison to DNT-OL-500 lens without PVP. The study demonstrated the successful delivery of olopatadine HCl and PVP-K30 from the doughnut contact lens for the extended period with limited alteration to the optical and swelling properties of contact lens.

    PURPOSE: Ocular anterior segment disorders (ASDs) are clinically and genetically heterogeneous, and genetic diagnosis often remains elusive. In this study, we demonstrate the value of a combined analysis protocol using phenotypic, genomic, and pedigree structure data to achieve a genetic conclusion.

    METHODS: We utilized a combination of chromosome microarray, exome sequencing, and genome sequencing with structural variant and trio analysis to investigate a cohort of 41 predominantly sporadic cases.

    RESULTS: We identified likely causative variants in 54% (22/41) of cases, including 51% (19/37) of sporadic cases and 75% (3/4) of cases initially referred as familial ASD. Two-thirds of sporadic cases were found to have heterozygous variants, which in most cases were de novo. Approximately one-third (7/22) of genetic diagnoses were found in rarely reported or recently identified ASD genes including PXDN, GJA8, COL4A1, ITPR1, CPAMD8, as well as the new phenotypic association of Axenfeld-Rieger anomaly with a homozygous ADAMTS17 variant. The remainder of the variants were in key ASD genes including FOXC1, PITX2, CYP1B1, FOXE3, and PAX6.

    CONCLUSIONS: We demonstrate the benefit of detailed phenotypic, genomic, variant, and segregation analysis to uncover some of the previously "hidden" heritable answers in several rarely reported and newly identified ocular ASD-related disease genes.

    Background: Varicella has been known to be a harmless childhood disease. However, it has been reported that severe complications have taken place following Varicella infection, in both immunocompetent, as well as immunocompromised, individuals. Cutaneous complications of Varicella may manifest as preseptal cellulitis, albeit rarely.

    Report: We present a case of a 4-year-old boy who presented with symptoms and signs of preseptal cellulitis following Varicella infection. He was referred to the otorhinolaryngology team for a nasoendoscopy to rule out sinusitis, in view of the fear that a child presenting with a swollen red eye may be a case of true orbital cellulitis. He was treated successfully with intravenous antibiotics and surgical drainage of the preseptal collection.

    Conclusion: It is imperative for clinicians to be aware that a simple Varicella infection may lead to cutaneous complications in the pediatric age group, especially in children who are 4 years and younger. They may develop preseptal cellulitis, whose presentation might mimic that of orbital cellulitis. Empirical treatment with antibiotics would be advantageous for the patient. A nasoendoscopic examination may also be warranted in these cases to rule out sinusitis as a cause of orbital cellulitis.

    PURPOSE: The aim of this study was to measure and compare the effect of topical insulin (0.5 units, 4 times per day) versus artificial tears (Vismed, sodium hyaluronate 0.18%, 4 times per day) for the healing of postoperative corneal epithelial defects induced during vitreoretinal surgery in diabetic patients.

    METHODS: This is a double-blind randomized controlled hospital-based study involving diabetic patients with postoperative corneal epithelial defects after vitreoretinal surgery. Diabetic patients were randomized into 2 different groups and received either 0.5 units of topical insulin (DTI) or artificial tears (Vismed, sodium hyaluronate 0.18%; DAT). The primary outcome measured was the rate of corneal epithelial wound healing (mm 2 /h) over a preset interval and time from baseline to minimum size of epithelial defect on fluorescein-stained anterior segment digital camera photography. The secondary outcome measured was the safety of topical insulin 0.5 units and artificial tears (Vismed, sodium hyaluronate 0.18%). Patients were followed up until 3 months postoperation.

    RESULTS: A total of 38 eyes from 38 patients undergoing intraoperative corneal debridement during vitreoretinal surgery with resultant epithelial defects (19 eyes per group) were analyzed. DTI was observed to have a significantly higher healing rate compared with the DAT group at rates over 36 hours ( P = 0.010), 48 hours ( P = 0.009), and 144 hours ( P = 0.009). The rate from baseline to closure was observed to be significantly higher in the DTI group (1.20 ± 0.29) (mm 2 /h) compared with the DAT group (0.78 ± 0.20) (mm 2 /h) as well ( P < 0.001). No adverse effect of topical insulin and artificial tears was reported.

    CONCLUSIONS: Topical insulin (0.5 units, 4 times per day) is more effective compared with artificial tears (Vismed, sodium hyaluronate 0.18%, 4 times per day) for the healing of postoperative corneal epithelial defects induced during vitreoretinal surgery in diabetic patients, without any adverse events.

    A 26-year-old female presented to the paediatric clinic at 11 years of age with poor growth. The detection of delayed puberty, anosmia, coloboma and hearing impairment led to a diagnosis of CHARGE syndrome. This was confirmed by a heterogenous de novo pathogenic variant c.6955C >T:p.(Arg2319Cys) detected in the CHD7 gene. Detailed assessment, including olfaction, ophthalmic and auditory examination should be part of the evaluation framework in children with delayed growth and puberty.

    Aim. To report a case of refractory fungal keratitis caused by Scedosporium apiospermum. Methods. Interventional case report. Results. A 47-year-old Malay housewife presented with left eye cornea ulcer as her first presentation of diabetes mellitus. There was no history of ocular trauma, contact lens used, or cornea foreign body. Scedosporium apiospermum was isolated from the cornea scrapping. Her cornea ulcer initially responded well to topical Amphotericin B within 3 days but subsequently worsened. Repeat cornea scrapping also yields Scedosporium apiospermum. This refractory keratitis was successfully treated with a combination of topical Amphotericin B and Voriconazole over 6 weeks. Conclusion. Scedosporium apiospermum keratitis is an opportunistic infection, which is difficult to treat despite tight control of diabetes mellitus and intensive antifungal treatment. The infection appeared to have very quick onset but needed long duration of treatment to completely heal. Surgical debridement always plays an important role as a therapeutic procedure as well as establishes the diagnosis through repeat scrapping.

    A 42-year-old man from Ghana presented with bilateral painful corneal perforations following ingestion of a sulphur-based antibiotic. Emergency bilateral penetrating keratoplasty was performed, with restoration of globe integrity. However, surgical complications arose such as non-healing epithelial defect, secondary infection, graft dehiscence, and mounting intraocular pressure. This case illustrates the challenges faced in managing corneal grafts in patients with already compromised ocular surfaces.

    Castleman disease (CD) is a rare lymphoproliferative disorder of unknown aetiology. It manifests in two distinct clinical presentations: unicentric and multicentric. Unicentric CD is rare and may present as an isolated neck mass. A 22-year-old man presented with a 6-month history of right neck swelling that occupied the posterior triangle of the right neck region. After surgical exploration, a solitary, well defined, and hyper vascular mass was excise. A histopathological examination confirmed the lesion as CD, hyaline-vascular variant. CD of the neck is a diagnosis that is usually not taken into consideration while evaluating neck masses due to its rarity and unassuming presentation. It should be keep in the differential diagnosis of neck masses as the clinical and radiological features evade a firm diagnosis. The treatment of unicentric CD is complete surgical excision, which cures the patient.
