  • CAUSES, COMPLICATIONS &TREATMENT of A“RED EYE”
    CAUSES, COMPLICATIONS & TREATMENT of a “RED EYE” 8 Most cases of “red eye” seen in general practice are likely to be conjunctivitis or a superficial corneal injury, however, red eye can also indicate a serious eye condition such as acute angle glaucoma, iritis, keratitis or scleritis. Features such as significant pain, photophobia, reduced visual acuity and a unilateral presentation are “red flags” that a sight-threatening condition may be present. In the absence of specialised eye examination equipment, such as a slit lamp, General Practitioners must rely on identifying these key features to know which patients require referral to an Ophthalmologist for further assessment. Is it conjunctivitis or is it something more Iritis is also known as anterior uveitis; posterior uveitis is serious? inflammation of the choroid (choroiditis). Complications include glaucoma, cataract and macular oedema. The most likely cause of a red eye in patients who present to 4. Scleritis is inflammation of the sclera.

  • Guidelines for Universal Eye Screening in Newborns Including RETINOPATHY of Prematurity
    GUIDELINES FOR UNIVERSAL EYE SCREENING IN NEWBORNS INCLUDING RETINOPATHY OF PREMATURITY RASHTRIYA BAL SWASthYA KARYAKRAM Ministry of Health & Family Welfare Government of India June 2017 MESSAGE The Ministry of Health & Family Welfare, Government of India, under the National Health Mission launched the Rashtriya Bal Swasthya Karyakram (RBSK), an innovative and ambitious initiative, which envisages Child Health Screening and Early Intervention Services. The main focus of the RBSK program is to improve the quality of life of our children from the time of birth till 18 years through timely screening and early management of 4 ‘D’s namely Defects at birth, Development delays including disability, childhood Deficiencies and Diseases. To provide a healthy start to our newborns, RBSK screening begins at birth at delivery points through comprehensive screening of all newborns for various defects including eye and vision related problems. Some of these problems are present at birth like congenital cataract and some may present later like Retinopathy of prematurity which is found especially in preterm children and if missed, can lead to complete blindness. Early Newborn Eye examination is an integral part of RBSK comprehensive screening which would prevent childhood blindness and reduce visual and scholastic disabilities among children. Universal newborn eye screening at delivery points and at SNCUs provides a unique opportunity to identify and manage significant eye diseases in babies who would otherwise appear healthy to their parents. I wish that State and UTs would benefit from the ‘Guidelines for Universal Eye Screening in Newborns including Retinopathy of Prematurity’ and in supporting our future generation by providing them with disease free eyes and good quality vision to help them in their overall growth including scholastic achievement.

  • Approach to Leukocoria Intro Hi Everyone, My Name Is
    PedsCases Podcast Scripts This is a text version of a podcast from Pedscases.com on the “Approach to Leukocoria.” These podcasts are designed to give medical students an overview of key topics in pediatrics. The audio versions are accessible on iTunes or at www.pedcases.com/podcasts. Approach to Leukocoria Developed by Chris Novak, Dr. Natashka Pollock and Dr. Mel Lewis for PedsCases.com. March 1, 2016 Intro Hi everyone, my name is Chris Novak. I am a medical student at the University of Alberta. Today’s podcast is designed to give medical students an organized approach to the physical exam finding of leukocoria, or an abnormal red reflex in children. This podcast was developed with Dr. Melanie Lewis, a general pediatrician and Professor at the University of Alberta and Dr. Natashka Pollock, a pediatric ophthalmologist at the Stollery Children’s Hospital in Edmonton, Alberta. The term leukocoria refers to a “white pupil” when examining the eye. In some cases leukocoria may be grossly apparent, or may be noticed by parents in photographs, however it is often an incidental finding on physical exam. While leukocoria is not a common finding, it is a critical sign of vision- and potentially life-threatening conditions including cataracts, hemorrhage, and malignancy like retinoblastoma. Different causes of leukocoria can present from the neonatal period and throughout childhood hence,the American Academy of Pediatrics recommends that all neonates have their red reflex examined before discharge from hospital, and subsequently at all well-child visits. Thus, it is important that all physicians looking after children recognize the critical nature of this presentation so that it is not missed.
