Effects of Prismatic Spectacle Lenses on Symptoms of Dizziness, Headache and Anxiety as Caused by...

Binocular DysfunctionVertical Heterophoria3 more

The purpose of this study is to demonstrate whether, in patients diagnosed with Vertical Heterophoria, the symptoms of dizziness, headache and / or anxiety are reduced or eliminated when a kind of correction called vertical prism is added to the patient's normal eye glass prescription. The experiment will involve giving the patient two pairs of glasses (one pair containing the baseline prescription with vertical prism (Standard Treatment Glasses) and the other pair containing the baseline prescription but without vertical prism (Placebo Glasses)) to demonstrate which pair of glasses is most effective in reducing the symptoms of dizziness, headache and / or anxiety in these patients.

The Effect of Binaural Sound on the Occurrence of Emergence Delirium in Children Undergoing Strabismus...

Emergence Delirium

The hypothesis of this study is that providing continuous binaural beats with a phase difference in alpha frequency during anesthesia can reduce the incidence of emergence agitation in pediatric patients. To test this hypothesis, the occurrence of emergence agitation will be compared between the group that received binaural beats and the group that did not receive binaural beats.

Deep Neuromuscular Blockade in Strabismus Surgery

Strabismus

The purpose of this study is to determine if inducing a moderate or greater neuromuscular block (TOF count 0-3) when performing a neuromuscular block in pediatric patients aged 3 to 18 years undergoing strabismus surgery under general anesthesia can reduce the incidence of the oculocardiac reflex.

Correction of V-pattern Strabismus by Graded Recession of Inferior Oblique Muscle .

V Pattern EsotropiaMonocular Exotropia With V Pattern

V pattern strabismus is the commonest of alphabet pattern. Its identification is essential to plan a proper surgical management. Graded recession is a very logical approach to treat inferior oblique overaction (IOOA). The aim Is to evaluate the efficacy of graded recession of inferior oblique muscle for correction of different grades of V pattern.

Amblyopia (Lazy Eye) Treatment Study

AmblyopiaAnisometropia1 more

The purpose of this study is to compare the results of two standard treatments for amblyopia in order to find out if one is more effective than the other. Amblyopia, which develops in childhood, is also called "lazy eye," because one eye is not being used properly. The brain favors the other eye for some reason, such as crossing or turning out of the eyes, and vision in the weak eye is reduced. Amblyopia is treated by forcing the child to use the weak eye. There are two ways to do this: 1) a patch placed over the "good" eye forces the child to use the weak eye; or 2) an eye drop placed in the "good" eye once a day to blur vision in that eye makes the child rely on the weak eye. The success rates with both of these methods have been reported to be about the same; this study will try to identify if one is more effective than the other. Children will be randomly assigned by computer to one of the following two treatment methods: Patch The child initially will wear a patch over the "good" eye for 8 to 12 hours every day. If vision in the weak eye improves, the patching time will be decreased. If vision remains good after 3 months, the patching will be stopped, unless the child's doctor believes treatment should continue. If vision in the weak eye does not improve, the patching time will be increased. Eye Drops The child will be given one drop per day of atropine in the "good" eye. If vision in the weak eye improves, the drops will be given less often. If the vision remains good after 3 months, the drops will be stopped, unless the child's doctor believes treatment should continue. If the initial daily drop does not improve the vision in the weak eye, the child's eyeglasses may be changed to try to further blur the vision in the "good" eye. After 6 months, treatment may be stopped if it has not been successful. If treatment has been successful after 6 months, it may be continued at a reduced amount or stopped. Follow-up visits will be scheduled every 4 weeks for the first 6 months and every 2 to 4 months after that until the end of the 2-year study. During each visit the eyes will be examined for eye movements and vision, and the pupils will be dilated to examine the inside of the eye.

Intravenous Versus Peribulbar Dexmedetomidine for Strabismus Surgery in Adults

Squint

Using various adjuvants has become a trend in regional anesthesia practice to improve the quality of anesthesia and prolong postoperative analgesia. Dexmedetomidine, an alpha-2 agonist has been proposed as a safe and effective adjunct capable of extending the duration of the single-shot block

Inferior Oblique Muscle Anteriorization Versus Anteriorization and Resection in DVD With IOOA

Dissociated Vertical DeviationInferior Oblique Overaction

The goal of this clinical trial is to compare the results of two surgical modalities in patients with Dissociated vertical deviation with inferior oblique muscle overaction . The main questions it aims to answer are: How much does the magnitude of DVD improve after each modality? Is the IOOA eliminated? Participants will be divided into two equal groups; Researchers will compare the efficacy of symmetrical anteriorization of the inferior oblique and adding an additional rescetion to one eye in the second group to see which group had more signifcant reduction in the magnitude of DVD and IOOA.

Binocular Treatment of Amblyopia Before and After Strabismus Surgery

AmblyopiaStrabismus

The primary objective of this study is to assess the effectiveness of an investigational binocular treatment in improving vision in strabismic amblyopes (i.e., patients with lazy eye, or poor vision in one eye due to a present or former eye misalignment). Patients will be randomized to receive the study treatment either before or after strabismus surgery (i.e., corrective eye alignment surgery) or sham treatment before surgery. The study hypothesis is that there will be no significant change in vision in neither the pre nor post-surgery groups and no significant change in vision in neither the sham nor actual treatment groups.
