Read Full License Page 1/14 Abstract Background: Accommodative esotropia (AET) is a common disease during childhood. In this literature review, we analyze and discuss the different methods of treatment for Accommodative esotropia. Methods: Articles about accommodative esotropia from 2007 to 2017 were retrieved from the PubMed database. We study the articles by title/abstract/all elds, after applying the inclusion and exclusion criteria, nally 9 articles were retained. We compared the effectiveness between these approaches to treatment. Results: All the refraction methods had an effectivity rate of > 50%. The bifocal lenses group showed a higher failure rate (15.58%) than the single-vision lenses group (5.19%). Extraocular muscle surgery can signicantly decrease deviation in patients who have AET with a high AC/A ratio (95.24%,71.30%,78.40%). After Botulinum toxin injection, the residual deviation was signicantly lower than that before the injection (90.44%) and this rate held stable until 12 months after the injection (85.71%) and then decreased to 71.43% at 18 months. The effectivity rate in the prism builders group (surgery with prism group) was signicantly higher than that in the prism non-builders group 100% vs.

  • Classification of Strabismus
    Classification of strabismus Pr Dr Monique Cordonnier Université Libre de Bruxelles Most prominent feature to have in mind = BINOCULAR VISION potential ? Yes or No If the strabismus was present during the first 6- 8 months of life, there is no This potential means that potential for treatment (……) may restore normal binocular binocularity, warranting vision stability and avoiding recurrences Binocular vision = eyes are like wheels on the rails of a railtrack 1 What is BINOCULAR VISION ? 1. Normal - Bifoveolar fixation with normal visual acuity in each eye, no strabismus, no diplopia, normal retinal correspondence, normal fusional vergence amplitudes, normal stereopsis. 2. Subnormal (abnormal) – 1 or more of the following; anomalous retinal correspondence, suppression, deficient to no stereopsis, amblyopia, decreased fusional vergence amplitudes. 3. Absence of Binocular Vision - no simultaneous perception, no fusion, no stereopsis Besides, the classification of strabismus is based on a number of features including : . The relative position of the eyes . The time of onset (=clue for binocular vision potential), . Whether the deviation is intermittent (=clue for binocular vision potential) or constant . Whether the deviation is comitant (supranuclear cause) or incomitant (nuclear or infranuclear cause, clue for binocular vision potential if the eyes are straight in one position) .

  • Surgical Treatment of Esotropia Associated with High Myopia: Unilateral Versus Bilateral Surgery
    Eur J Ophthalmol 2010; 20 ( 4): 653 - 658 ORIGINAL ARTICLE Surgical treatment of esotropia associated with high myopia: unilateral versus bilateral surgery Yair Morad, Eran Pras, Yakov Goldich, Yaniv Barkana, David Zadok, Morris Hartstein Department of Ophthalmology, Assaf Harofeh Medical Center, Tel Aviv University, Zerifin - Israel PUR P OSE . To compare unilateral versus bilateral surgical treatment of esotropia associated with high myopia. METHODS . This retrospective study comprised patients who underwent surgery for esotropia with high myopia performed by the first author (Y.M.) between 2003 and 2008. Surgical results and complica- tions were compared between patients who underwent unilateral versus bilateral surgery. RESULTS . Nine patients were identified with average age of 44.9 years (range 8–70 years). All had bilate- ral high myopia (average –13.35 D, range –9.00 to –17.50 D) and esotropia of 20–75 diopters, together with hypotropia in 5 cases. Bilateral displacement of the lateral rectus inferiorly and superior rectus medially was demonstrated in each patient by computed tomography scan of the orbits and by ob- servation during surgery. Five patients underwent bilateral surgery and 4 underwent unilateral surgery. After an average follow-up of 29 months (range 4–47 months), 4/5 patients who underwent bilateral myopexy achieved good results with postoperative esotropia of less than 8 diopters, as opposed to 2/4 patients who underwent unilateral surgery. No complications were noted. CON C LUSIONS . Bilateral superior and lateral rectus myopexy is the preferred method of surgical correc- tion of esotropia associated with high myopia. Additional unilateral or bilateral medial rectus reces- sion is probably not indicated in most cases.

Corresponding author: Dr. Jitendra Kumar Abstract Purpose - To study the ophthalmic manifestations in childrens presenting with Down syndrome. Methods- This was a prospective observational study that involved 30 eyes of 15 childrens of Down syndrome presenting with low visual acuity, strabismus, nystagmus, blephritis, large epicanthal folds, nasolacrimal duct obstruction , etc. Results-There were 9 males and 6 females and the age group taken was 1 to 10 years. Most common presentation in down syndrome patients is low visual acuity ( <6/18 ) in 74% patients followed by strabismus in 68 % patients , nystagmus in 52% patients , upward slanting palpaberal fissure in 51% patients , blephritis in 34% patients, nasolacrimal duct obstruction in 32% patients ,brushfield spots in 14% patients. Most common refractive error in down syndrome children is myopia in 46% patients followed by astigmatism in 32% patients and hyperopia in 22% patients. Fundus finding are rare in downs syndrome patient but include cupping of disc and optic atrophy. Other features of down syndrome are cerebral palsy, autism , hypertelorism, flat nasal bridge, alopecia and macroglossia. Conclusion - Down syndrome is common genetic disease presenting usually with multiple systemic features.
