AIM: To explore the associations between various characteristics of Malaysian cataract patients and their management, and their post-operative visual outcomes, to inform relevant bodies to reduce cataract-related blindness. METHODS: We conducted a descriptive secondary data analysis of cataract surgery patients in Melaka Hospital, from 2007 to 2014 using the National Eye Database (NED). Patient-related factors (demographic features, systemic and ocular comorbidities) and management-related factors (surgical duration, type of surgery, type of lens) were analysed for their association with visual outcome (acuity)...

The efficacy of oral acitretin in the systemic treatment of severe and recalcitrant dermatoses has been established in a large number of clinical trials. Its mucocutaneous and ocular adverse reactions are common or relatively common, whereas systemic side effects are either uncommon or rare and include teratogenesis, hyperlipidemia, hepatotoxicity, intracranial hypertension, myopathy, and peripheral neuropathy. Angioedema is a term used to describe an acute, solitary or multiple, circumscribed, and non-pitting mucocutaneous swelling that affects the dermis and the subcutaneous tissue, lasts 24 to 72 hours, and may become potentially life-threatening when the pharynx and/or the larynx are involved...

Glaucoma is a progressive neuropathy characterized by the loss of retinal ganglion cells (RGCs). Strategies that delay or halt RGC loss have been recognized as potentially beneficial for rescuing vision in glaucoma patients. Quercetin (Qcn) is a natural and important dietary flavonoid compound, widely distributed in fruits and vegetables. Mounting evidence suggests that Qcn has numerous neuroprotective effects. However, whether Qcn exerts neuroprotective effects on RGC in glaucoma is poorly understood. In this study, we investigated the protective effect of Qcn against RGC damage in a rat chronic ocular hypertension (COHT) model invivo and hypoxia-induced primary cultured RGC damage in vitro, and we further explored the underlying neuroprotective mechanisms...

The value of ICT is important in diagnosis of the diseases of the eye and orbit Methods for direct measurement of intracranial pressure (ICT) are exact, but they are invasive and there is some risk of infection and damage of the tissue. Currently there are 2 valid indirect methods of mesurement of IKT. Digital Ophthalmodynamometry (D-ODM) and Transcranial Doppler ultrasonography (TDU). D-ODM is a non-invasive method for measuring of the Pulsating Venous Pressure (VPT). We can measure VPT by the pulse phenomena...

OBJECTIVE: The cribriform plate is a threshold of the intraocular pressure (VOT) and of the intracranial pressure (IKT). The difference between the VOT and IKT is referred to as translaminar gradient (TLG). The goal was to evaluate the Glaucoma progression (visual field, fundus examination, HRT) with / without topical anti-glaucomatous therapy) in relation to the TLG. PATIENTS AND METHODS: the significance of TLG has been studied in two groups. I. Group: 57 patients diagnosed and treatment of Primary Open-Angle Glaucoma (PGOU), 10 patients with Ocular hypertension (OH), 7 patients with Normal-Tension Glaucoma (NTG), and 75 healthy without glaucoma...

Glaucoma leads to blindness but there are diagnostic and therapeutic developments that aid ophthalmologists in the improved mangement of the disease compared to the past. Known risk factors such as age, myopia, dark pigmented skin, genetics, and elevated intraocular pressure play an important role for the individual patient's prognosis, and many yet unknown or not sufficiently investigated risk factors come along. The structured examination of the optic nerve head is crucial for the clincial diagnosis by the ophthalmologist...

Neovascular glaucoma (NVG), caused by ocular ischemia, is a serious ocular disease complicated by intractably increased intraocular pressure. Cerebrovascular accidents are classified into ischemic and hemorrhagic stroke. Based on the similar pathogenic mechanisms of NVG and ischemic stroke, we investigated the relationship between NVG and stroke by using a nationally representative sample. This study included 416 NVG patients and 4160 controls. Medical comorbidities were also evaluated. The cumulative incidence of ischemic stroke was 15...

Steroids are a group of anti-inflammatory drugs, commonly used to treat ocular and systemic conditions. Unmonitored use of steroids especially in eye drop formulations is common in situations when it is easily available over-the-counter, resulting in undesirable side effects. Among the ocular side effects, cataract and glaucoma are common. Steroid-induced ocular hypertension was reported in 1950, when long-term use of systemic steroid was shown to increase the intraocular pressure (IOP). Chronic administration of steroids in any form with raised IOP can cause optic neuropathy resulting in steroid-induced glaucoma...

Previous studies have demonstrated that 5ɑ-androst-3β,5,6β-triol (Triol), a synthesized steroid compound, showed notable neuroprotective effect in cultured cortical neurons. In the present study, we explored whether and how Triol have neuroprotective effect on retinal ganglion cells (RGCs) in a chronic ocular hypertension (COH) rat model. COH model was produced by injecting superparamagnetic iron oxide micro-beads into the anterior chamber, and Triol was administrated (4.8μg/100g, i.p., once daily for 4 weeks)...

The constellation of ocular symptoms known as Balint syndrome is a rare disorder seen in bilateral parieto-occipital lesions and is most frequently due to arterial occlusive disease or acute hypertension. Here we present the case of a patient with tacrolimus-induced posterior reversible encephalopathy syndrome (PRES) who presented with optic ataxia, simultanagnosia, and ocular apraxia. These ocular findings, consistent with Balint syndrome, are rarely the initial presentation of PRES. This case highlights the importance of early recognition of this unusual phenomenon, as well as the importance of an individualized rehabilitation plan to maximize functional independence in these patients...
