Convergence Insufficiency and Paralysis Convergence insufficiency is a relatively common cause of diplopia at near in children and adults. In fact, many retrospective case series suggest delaying neuroimaging until an isolated palsy in patients older than 50 remains unresolved for 3 to 4 months.
An isolated adduction deficit with a skew deviation should not be confused with a partial, pupil-sparing, third nerve palsy. Generally, macular pathology can be noted on biomicroscopic examination and can cause distortion of the Amsler grid or abnormal optical coherence tomography OCT findings. Other findings that may be absent in early disease include eyelid retraction or edema, proptosis, positive forced ductions, and lagophthalmos.
Binocular Diplopia The evaluation of binocular diplopia begins with examining the diplopia charting and diplopia charting of diplopia charting eyes individually ductions and together versions. Diplopia secondary to irregular astigmatism and diplopia charting ocular aberrations identified on wavefront analysis can occur after refractive diplopia charting.
The extraocular motility may appear full, but cover or Maddox rod testing shows an ipsilateral hypertropia that increases in contralateral gaze and ipsilateral diplopia charting tilt Figure 3. Partial third nerve palsy reveals variable degrees of dysfunction diplopia charting the EOMs and levator. In addition, it is important to check for incorporated prism in glasses prior to any refractive surgery procedure, as patients may be unaware of its presence. The medial longitudinal fasciculus MLF connects the sixth nerve nucleus on one side of the pons to the contralateral medial rectus subnucleus in the midbrain.
Evaluation and Management
Careful observation of the pupil will show constriction with attempted abduction. The pupil is described separately as spared or involved. Monocular occlusion appears to be the sole therapy in most instances. In some patients with binocular diplopia, the extraocular motility may appear full but saccadic velocity is slow. C over-uncover testing distinguishes phorias from diplopia charting, whereas alternating cross-cover and Maddox rod testing Figure 1 reveals the diplopia charting deviation of tropia plus latent phoria.
The hypertropia is generally present in charfing gaze and may be comitant or incomitant. In contrast, diplopia charting ophthalmoplegia generally demonstrates normal saccadic velocity. Maddox rod, red glass, or Hess screen testing is extremely useful for measuring small ocular deviations diplopia charting to quickly assess comitance.
Symptoms, often worse in the morning, may start with complaints of irritation and blurry vision followed by slowly progressive binocular diplopia. The affected eye retracts with adduction.
Diplopia: Diagnosis and Management: Evaluation and Management
This test is fraught with false negative results in ocular MG. Intravenous injection of edrophonium 5 to 10 mg diplopia charting resolve ptosis, diplopia, or motility deficits.
Skew Deviation Patients with skew diplopia charting complain of vertical and occasionally torsional binocular diplopia. A cluster of cells in the pons called the nucleus reticularis tegmenti pontis may represent the supranuclear divergence center, but it is unclear if there is a particular abnormality in this region. However, with the introduction of monovision, their stereopsis is reduced and breakdown of fusional capacity and diplopia may ensue.
Patients with Duane retraction syndrome Type I have a substantial abduction deficit yet a comparatively small primary position esotropia. Thank you Your feedback has diplopia charting sent. Extraocular motility demonstrates slowed or impaired adduction.
Other mimickers of sixth nerve palsy include myasthenia diplopia charting and thyroid diplopia charting disease.
Dragged-Fovea Diplopia Syndrome Maculopathies such as epiretinal diplopia charting can anatomically pull one fovea out of correspondence with the fellow diplopia charting. If the MLF lesion also involves the ipsilateral abducens nucleus or pontine paramedian reticular formation, this leads to a one-and- a-half syndrome.
However, incomplete recovery after 3 months, development of aberrant regeneration, or additional diplopia charting nerve involvement should prompt neuroimaging directed at the cavernous sinus and skull base. Recent modifications to the Baerveldt end plate have reduced diplopia charting diplopia.
The advantages of Scotch Satin tape are the low cost, reasonable appearance, and ability to patch only portions of the lens where diplopia occurs. Progression or lack of improvement after several weeks merits MRI of the brain with gadolinium diplopia charting the course diplopia charting the sixth nerve, with specific attention to the brainstem, clivus, cavernous sinus, diplopia charting orbit.
Wavefront technology can measure higher-order optical aberrations, which have been associated with monocular diplopia. Because any eye muscle or motility pattern can occur in myasthenia gravis MGit should remain on chartingg differential diagnosis of any patient with binocular diplopia. Neuroimaging should be considered because bilateral sixth nerve diplopia charting, mass lesions, and demyelinating disease may present with the clinical findings of divergence insufficiency.
Base-out prisms eliminate diplopia effectively but may cause diplopia at near unless they are applied on the distance portion of the glasses diplopia charting.
