Introduction: Angle kappa is important in our clinical practice as it can give the appearance of strabismus. A vertical angle kappa is secondary to macula heterotropia as a result of retinal traction from scar tissue in the posterior pole. Case report: We present an interesting case of a 25 year-old Chinese female who presented with an abnormal vertical angle kappa due to macula ectopia from a ...

From an analysis of the cases in the Strabismus Clinic in the New Haven Dispensary some facts are presented concerning: 1) the different types of squint; 2) amblyopia; 3) the incidence of surgical advisability; and 4) hypertropias. Muscle cases in the New Haven Dispensary were segregated into a special strabismus clinic, carried on in connection with the regular clinic, during 1933-34. The stra...

OBJECTIVES To test the previous findings of Enright that disparity-induced vertical vergence is mediated primarily by the oblique muscles, and to relate this normal eye movement pattern to the eye movement pattern seen in subjects with dissociated vertical deviation. METHODS Sixteen normal volunteers underwent 55 measurements of the cycloversion associated with prism-induced vertical vergence...

AIMS To study binocular function in patients with longstanding asymmetric keratoconus. METHODS In 20 adult patients with longstanding asymmetric keratoconus managed with a scleral contact lens a full clinical and orthoptic assessment was performed with and without the scleral contact lens in the poorer eye. RESULTS All 20 patients had a corrected acuity of at least 6/9 in their better eye. ...

Background: Consideration of current medications and their interactions as a source new onset oculomotor dysfunction is imperative for providing good eye care. Medication etiology should be particularly suspected when the symptoms begin with initiation medication resolved discontinuation same medication. Case Reports: Presented are two cases demonstrating that it prudent to aware capable induci...

PURPOSE We report a case of inferior rectus muscle aplasia in a 65-year-old woman. METHODS Images were obtained using ocular motility photography and magnetic resonance imaging (MRI), and operative findings were analyzed. RESULTS A 65-year-old woman presented with marked right hypertropia. The right eye also had microcornea, iris coloboma, and completely restricted downward movement. MRI sh...

ATTEMPTED INFRA-LAEVOVERSION: Mild right divergent squint (Fig. ia). Left hypertropia. Right eye abducted normally and showed nystagmoid movements (Fig. ib). Right eye hypertropic and showed defect of adduction. Left eye abducted normally (Fig. Ic). Right eye diverged mildly with no elevation. Left eye moved up and inwards (Fig. id). Right eye showed defective abduction and no elevation. Left e...

A 51year-old man presented with binocular diplopia on the three days after the snakebite in the fifth finger of the right hand by an Agkistrodon blomhoffi (mamushi). In the primary position he had an exotropia and right hypertropia, which became apparent when his head was tilted to the right. From ocular angle of deviation measured by synoptophore and Hess chart test, he was diagnosed as having...
