Abnormal binocularity, recurrence even after a successful treatment in at least 25% of amblyopic children, poor compliance and negative outcomes including distress, and low self-perception of social acceptance hinder the success of patching treatment. Patching the healthy eye has a long history and is the current standard treatment with at least one to two line improvements in VA in the amblyopic eyes however, it is faced with several limitations. Refractive correction is the first step of amblyopia treatment regardless of the cause of amblyopia (anisometropia, strabismus, or both). The most common risk factor for unilateral amblyopia is anisometropia. Amblyopia is mainly associated with visual acuity (VA) reduction and binocular dysfunction. It follows from inadequate stimulation of the visual system during the critical period of visual development. Registered on 22 April 2019.Īmblyopia, as a neurodevelopmental preventable visual disorder, affects approximately 1.1% in Asia. Iranian Registry of Clinical Trials IRCT20180217038768N1. The results will be disseminated in a peer-reviewed journal. Thus far, the recruitment of participants has not been completed and is scheduled to end in September 2021. The Ethics Committee of Mashhad University of Medical sciences’ approval date was February 28, 2018, with a reference code of IR.MUMS.fm.REC.1396.783. The primary outcome is to change visual acuity in the amblyopic eye from the baseline to 3 months after randomization. Those in the control group will receive patch therapy according to amblyopia treatment study protocol. In the intervention group, amblyopia treatment is provided with red-green anaglyphic glasses and a red filter placed in front of the amblyopic eye, along with a game to be played for 30 min twice a day. Forty-four patients between 4 and 12 years diagnosed with amblyopia will be randomly assigned to the control and intervention groups. This study has been designed as a non-inferiority, randomized, two parallel-group, controlled trial. To address this, the present research, designs, develops, and evaluates a new binocular game to treat amblyopia. Whether the binocular playing game treatment is comparable to patching treatment needs further randomized clinical trials. A binocular approach to treating amblyopia has been recently proposed. The dizziness caused by vertical heterophoria can also lead to trouble balancing, which can make everyday actions like going up the stairs dangerous.Amblyopia, as a neurodevelopmental preventable visual disorder, affects approximately 1.1 % in Asia. Uneasiness if places with high ceilings, due to sensory overload or disorientation due to a high level of visual stimuli.The perception that stationary objects at the edges of your vision are moving.Generally anxiety regarding driving, due to concerns about experiencing dizziness while behind the wheel.Perception that signs and stoplights are moving or that your vehicle is moving backward even while you are pressing the break, which makes it hard to come to complete stops when required.Particular issues which may occur include: AnxietyĪnxiety, specifically while driving, is also a common symptom of vertical heterophoria. Neck and shoulder pain can result from head tilting to compensate for the vision difficulties caused by the misaligned eyes. Those suffering from vertical heterophoria may also experience a feeling of heaviness near the crown of the head, comparable to the pressure from sinus pain. The intensity of these headaches can also vary. Other signs you have vertical heterophoria include head pain (specifically at the temples, forehead, and the back of the head). straightening up quickly after bending over. Vertical heterophoria can lead to a number of symptoms, some of which might not be immediately associated with vision.įeelings of dizziness can come and go for someone with vertical heterophoria, and it can be triggered by a range of actions, such as”
