Department of Ophthalmology, School of Medicine in Katowice, Medical Anna Heinke University of Silesia, Katowice, Poland Katarzyna University Clinical Center, University Hospital Medical University of Silesia, Michalska- Katowice, Poland *Corresponding Author Małecka* ABSTRACT Purpose: The aim of this study was to evaluate the effectiveness and safety of treatment with aibercept administered intravitreally in patients with neovascular age-related macular degeneration after rst year of treatment. Moreover, the inuence of following factors on therapeutic success with aibercept was investigated: CNV type, lens status (pseudophakic vs phakic), patient's age, sex and the fact if patient was previously receiving anty-VEGF injections. Methods: A prospective clinical study was conducted on 90 eyes of patients (age 56 to 89 years old, 50 females, 40 males) who were diagnosed with choroidal neovascularisation (CNV) due to wet AMD. Before each injection best corrected visual acuity(BCVA) on Snellen chart, converted then to ETDRS scale for statistical purposes and central retinal thickness (CRT) using optical coherence tomography (OCT) were assessed. All patients received 3 doses of 2,0 mg intravitreal aibercept every 4 weeks, followed by aibercept injections every 2 months. The primary endpoint of the study was determined on best corrected visual acuity (BCVA) and changes observed in central retinal thickness (CRT) 3 months and 1 year after treatment with aibercept comparing with BCVA and OCT at the baseline. Results: After the rst year of treatment with aibercept a statistically signicant improvement of mean BCVA was observed.

D. King Abdul-Aziz University, Saudi Arabia, 2013 Kansas City, Missouri 2020 © 2020 MESHAL ALSHAMRANI ALL RIGHTS RESERVED TOPICAL CLEAR AQUEOUS NANOMICELLAR FORMULATIONS FOR AGE-RELATED MACULAR DEGENERATION Meshal Alshamrani, Candidate for the Doctor of Philosophy Degree University of Missouri-Kansas City, 2020 ABSTRACT Disorders affecting the posterior segment of eyes represent a significant burden to healthcare and patients’ wellbeing. Among the back of the eye disorders, age-related macular degeneration (AMD) is one of the major ailments responsible for blindness worldwide. There is currently no effective treatment available to cure AMD completely. Anti-VEGF therapy is currently considered the treatment of choice. However, it is invasive and does not offer substantial long-term relief to AMD patients. Other treatment options include thermal laser photocoagulation and surgery. None of these therapeutic approaches are safe and effective. Hence there is a real need for the development of an alternative therapeutic approach that is safe, effective and non-invasive. The objective of this study is to develop a clear, aqueous drug-loaded nanomicellar formulation utilizing FDA approved polymers, namely Hydrogenated castor oil 40 (HCO-40) and Octoxynol 40(OC-40) as a potential-therapeutics for AMD. Hydrophobic drugs such as curcumin (CUR), celecoxib (CXB), and resveratrol (RSV) were successfully solubilized and entrapped in the core of the nanomicelles. These nanomicellar constructs efficiently utilize their hydrophilic corona and evade the wash-out into the systemic circulation from both the conjunctival and choroidal blood vessels and lymphatics, thus overcoming the dynamic barrier.

L Lambert *Corresponding author, [email protected] Abstract A red eye is the cardinal sign of ocular inflammation, and is one of the most common ophthalmological complaints. Inflammation of almost any part of the eye, including the lacrimal glands and eyelids, or a faulty tear film, can lead to a red eye. The condition is usually benign, self-limiting and can be managed effectively in general practice. While there may be numerous causes of a red eye, conjunctivitis is the most common. A thorough patient history and physical examination of the eye are essential in the management of a red eye when differentiating between an allergic and an infectious cause. Keywords: red eye, allergy, infection, inflammation, conjunctivitis, viral, bacterial Introduction • Unilateral or bilateral eye involvement A red eye is caused by the dilation of blood vessels in the eye, • The duration of symptoms and is one of the most common ocular complaints experienced • The type and amount of discharge by patients.1,2 The diagnosis of a red eye may be aided by the • Visual changes differentiation between ciliary and conjunctival injection or redness: • The severity of the pain • Ciliary injection involves branches of the anterior ciliary • Photophobia arteries, and indicates inflammation of the cornea, iris or ciliary • The presence of allergies or systemic disease.

Partnership Research News Author Mashael AL-Namaeh, OD., PhD, FAAO Title Ocular Manifestations of Parkinson’s Disease Summary Parkinson's disease (PD) is the world's second-most-common neurological disease, after Alzheimer’s disease. Parkinson disease occurs in approximately 13 per 100,000 people, and about 60,000 new cases are identified each year in the United States. PD affects more than 4 million people worldwide. Diplopia, reduced visual acuity, pupil abnormalities, saccade abnormalities, smooth pursuit eye movement abnormalities, Convergence Insufficiency (CI), vergence abnormalities, strabismus, decreased reading time, and vertical gaze abnormalities have all been associated to Parkinson's disease. Other signs of PD include dry eyes and abnormal ocular surface staining. Blink rates and corneal sensitivity are reduced in PD patients. The rate at which people blink was linked to the sensitivity of their corneas, which could be linked to asymptomatic ocular surface disease caused by decreased corneal sensitivity. Other symptoms, such as visual hallucinations should be investigated further in future investigations. Finally, because there is an association between diplopia and CI in PD, binocular vision testing is critical. Publication Information 1.Al-Namaeh M.

  • Subconjunctival Haemorrhage-ENG
    How to Care for Your Child with Subconjunctival Hemorrhage This leaflet will provide you with information about Subconjunctival Hemorrhage, causes, symptoms, diagnosis, treatment and home care advice. What is Subconjunctival Hemorrhage (bleeding)? Subconjunctival bleeding is a red spot on the white of the eye representing a collection of blood between the sclera and conjunctiva. Subconjunctival bleeding can be caused by: o Coughing, sneezing or vomiting o Minor injury to the eye o Rubbing the eye What are the symptoms of Subconjunctival bleeding? o Subconjunctival bleeding can look scary but usually cause no pain. o Occasionally your child may have a foreign body sensation. o The spot gets typically bigger in the rst 24-48 hrs before it starts to fade away. Sidra Medicine PO BOX 26999 Doha, Qatar +974 4003 3333 www.sidra.org How is Subconjunctival bleeding diagnosed? The doctor will ask few questions about your child's health and examine your child. Usually, no further investigation or blood tests are required. How is Subconjunctival bleeding treated? No treatment is usually required. Most will go away within 1-3 weeks. Sometimes if your child's eye feels irritated, your doctor may prescribe artificial tears drops to soothe the eye. Home care advice o Reassure your child that the spot will fade on its own. o The red spot on the eyeball may change colour as it heals. This is like a bruise on the skin, it may change from red to brown to purple to yellow. o If your child wears contact lenses, avoid wearing them until the red spot has dis appeared.
