  • 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.

  • Squints Occur When the Eyes Do Not Work As a Team
    Squints occur when the eyes do not work as a team. One eye may look forward while the other looks in a different direction (that eye may turn inwards, outwards, upwards, or even dow nwards, while the other eye looks forward). Medically the term for this is called “Strabismus” (being cross-eyed) and is actually a fairly common occurrence affecting 2 to 3% of the population. Usually it affects younger children between the ages of 18 months and 4 years of age. Risk factors for developing a Causes squint • The exact cause of most childhood squints has • Positive family history (i.e. if a parent never been discovered – this is termed has had a squint or needed glasses from idiopathic an early age, there may be an increased • This, however, does not mean that it cannot chance that their child may also be be corrected affect ed) • Prematurity and low birth weight Certain conditions can result in a squint: • Cerebral palsy and Down syndrome • Refractive errors – this is due to the eye’s • Tumours (in rare cases) inability to focus correctly on an object. Conditions such as short sightedness, far sightedness, and astigmatism may cause one or both eyes to turn inwards (esotropia) or outwards (exotropia). • Any condition that causes one or both eyes to have poor vision. Conditions such as Congenital cataracts or damage to the cornea, optic nerve or retina can adversely affect vision and therefore, the affected eye can no longer look forward, resulting in a squint • Some squints only occur when the eyes are looking in certain directions.

  • Squint Information Booklet
    Squint Your Questions Answered Patient Information Leaflet RVEEH, Squint January2014. Ref No: PIL 023 Version 2 What is a Squint? A squint, or strabismus, occurs when the eyes are misaligned and are no longer working as a pair. It is common in childhood, affecting 2-3% of the population. The most common types of squint occur when one eye turns inwards (a convergent squint, or esotropia), or outwards (known as a divergent squint, or exotropia). However, it is also possible to have a vertical squint (hyper- or hypotropia) or even a torsional squint, where the eye is rotated inwards or outwards. Squints in childhood should be treated early to avoid amblyopia (see below) and to try to preserve binocular vision. What causes a squint? There are many different types of squint. Childhood squints are often caused by a need for glasses. Convergent squints are the most common type and these are usually caused by hyperopia, or long-sightedness, where the effort required by the child to over-focus the eyes eventually causes one of them to turn in. The hyperopia is present since birth, but the squint usually develops between the ages of 18 months to 3 years. Esotropia in the left eye. When the long-sightedness is corrected, the eyes become straight RVEEH, Squint January2014. Ref No: PIL 023 Version 2 Childhood squints can be hereditary. They often start off intermittently, especially when the child is tired or unwell. They never go away on their own, but they do often improve with time. Occasionally, they require surgery. Rarely, squints can be caused by defects at the back, or behind the eye.

  • Your Child's Squint Surgery
    Patient and Carer Information Your Child’s Squint Surgery What is a squint? A squint or strabismus occurs when the eyes are not aligned properly, e.g. one eye may turn inwards, outwards, up or down. A convergent squint refers to an eye that turn inwards, and a divergent squint refers to an eye that turn outwards. Sometimes one eye may be higher or lower than the other (vertical squint). The squint may be constant (present at all times) or occur only intermittently. Most squints are managed by prescribing appropriate glasses and in some cases patching to improve vision in the squinting eye. The aim of squint surgery in most cases is to straighten the eyes, to give a better cosmetic appearance or to correct a head posture. Surgery can sometimes improve the ability of the two eyes to work together as a pair and provide better quality vision. Surgery does not eliminate the need for glasses and does not correct your child’s vision. Two weeks prior to your child’s surgery, you will meet with the Orthoptist and the Ophthalmologist. The squint will be re-measured. You will have the opportunity to discuss the surgery and ask further questions. You will sign a consent form. We will not perform the operation if your child has a cough or cold. The operation will be deferred for at least two weeks to allow a full recovery. Please inform Woodlands ward if your child is unwell. Squint Surgery During Squint surgery, the position of one or more eye muscles is changed.

  • Severity of Amblyopia and Its Correlation with the Amount of Refractive Error
    84 Ophthalmol Ina (2015) 41:1 Original Article Severity of Amblyopia and Its Correlation with The Amount of Refractive Error Ria Sandy Deneska Refraction and Contact Lens Division, Department of Ophthalmology, Faculty of Medicine Airlangga University/ dr Soetomo General Hospital, Surabaya ABSTRACT Background: To analyze the correlation between the severity of amblyopia and the amount of refractive error Methods: Patients in outpatient clinic dr Soetomo General Hospital, who was diagnozed as amblyopia, from November 2011 – January 2013, were enrolled in this retrospective study. All subjects were evaluated for subjective refraction using Snellen Chart and objective refraction using streak retinoscopy. The severity of amblyopia determined by the BCVA and the amount of refractive error stated by the spherical equivalent and the amount of cylindrical errors. Result: The subjects of this study was 40 patients (73 eyes) with age 5-11 years old. The range of BCVA was 0,1-0,8 logMAR units, the spherical equivalent of refractive errors were minus 1,5D – 12,75D and the cylindrical errors were minus 0,50 – 5,00D. Statistically, there was correlation between the severity of amblyopia and the spherical equivalent of refractive errors, but there was no correlation with the cylindrical errors. Conclusion: The severity of amblyopia has a correlation with the amount of spherical equivalent of refractive error, but has no correlation with the amount of astigmatism. Key words: Amblyopia, Spherical Equivalent, Cylindrical Error Amblyopia, also referred by the public as “lazy following: strabismus, anisometropia or high eye”, is a unilateral or, less commonly, bilateral bilateral refractive errors (isometropia), and reduction of best-corrected visual acuity that stimulus deprivation (Rouse et al 1994, Raab et al cannot be attributed directly to the effect of any 2011, Gunawan 2012).
