    ABSTRACT: Aim: Investigate the frequency and type of visual symptoms following stroke. Design: Prospective multicenter cohort study (Vision in Stroke [VIS]) in accordance with Declaration of Helsinki. Methods: Standardized referral/investigation protocol with detailed assessment of visual acuity, ocular alignment/motility, visual field and visual perception, plus quality of life score. Results: A total of 915 patients were recruited with a mean age of 69.18 years (standard deviation 14.19). Reported symptoms included diplopia, blurred vision, reading difficulty, field loss, perceptual difficulty, and oscillopsia. Sixteen percent (149) had no visual symptoms: 22 patients had normal eye examinations by orthoptic assessment and 127 had diagnoses of central/peripheral visual loss, ocular motility or perceptual abnormalities. Eighty-four percent had visual symptoms, but 50 patients had normal eye examinations. There was no significant difference in type of symptom and quality of life score. Treatment included refraction, prisms, occlusion, orthoptic exercises, low vision aids, and advice. Conclusions: Of those with no visual symptoms, 85% had objectively measured visual impairment. Conversely, 6.5% of those with visual symptoms had normal orthoptic examinations. Thus the presence or absence of visual symptoms does not infer absence or presence of visual impairment and may relate to recovery of visual impairment, cognitive, or communication impairment.

    ABSTRACT: To identify the predictors for motor outcome and response to surgical treatment of primary exotropia. Taunton and Somerset Hospital, Somerset, United Kingdom. Retrospective analysis of the surgical treatment of primary exotropia performed in our department over a period of 12 years from April 1991 to May 2003. Case-notes of the patients who had surgical treatment for primary exotropia for the specified period were identified by a hospital computer database (MDI coding). All case-notes were reviewed and the following data were recorded and used for statistical analysis: age at the time of surgery, type and severity of exotropia, presence of amblyopia, AV pattern and vertical deviation, the level of stereopsis, type of surgery, and motor and cosmetic results. The surgical outcome was determined as good motor outcome if tropia was within 10 PD of orthotropia. The response to surgery was derived from the difference between the preoperative and postoperative angle of deviation for distance per amount of muscle surgery in millimetres. A total of 124 cases were included in the study. Good motor outcome was achieved in 83 (67%) cases. There was a positive correlation between the preoperative angle of deviation at distance and dose response to surgery (r = 0.6 and p < 0.001) and a negative correlation between average corrected visual acuity and response (r = -0.21 and p = 0.025). There was a statistically significant negative relationship between preoperative stereopsis and response to surgery (p = 0.02). Surgical treatment for exotropia is effective and the dose response is correlated to the preoperative angle of deviation and average visual acuity. Poor or no preoperative stereopsis was associated with better response to surgery.

    ABSTRACT: The aim of this study was to investigate the spatial and temporal distortions that occur in strabismic and anisometropic amblyopic vision. Twelve subjects with strabismic (n = 4), anisometropic (n = 4), mixed amblyopia (n = 3) and bilateral refractive amblyopia (n = 1) were asked to describe and sketch their subjective percept of different geometrical patterns, as seen with their amblyopic eye. Based on their descriptions, computer-animated patterns were generated, which were then validated by the subjects. Both spatial distortions and temporal instability were perceived mainly by strabismic and strabismic-anisometropic amblyopes. Temporal instability occurred mainly at high spatial frequencies. Our data suggest that strabismus, in addition to amblyopia, is needed to elicit significant spatial and temporal distortions. The occurrence of these distortions may be related to the early history of each subject.

    ABSTRACT: To investigate heterotropia, heterophoria, head posture, nystagmus, stereo acuity, ocular motility and near point of convergence (NPC) in children with hydrocephalus treated surgically before 1 year of age. In addition, the effects of being born with hydrocephalus, the effect of the etiology of hydrocephalus, number of shunt revisions and the size of the ventricles on these variables were studied. A population-based study was performed in 75 children and the results were compared with the results of an age- and sex-matched group (comp group) (n = 140). Heterotropia 68.9% (comp group 3.6%; p < 0.001), abnormal head posture 41.3% (comp group 0; p < 0.001), nystagmus 44.0% (comp group 0; p < 0.001), stereo acuity < or =60'' 33.8% (comp group 97.1%; p < 0.001) and ocular motility defects 69.7% (comp group 0.7%; p < 0.001) were more common among children with hydrocephalus than in the comparison group. Children with overt hydrocephalus at birth had significantly more heterotropia (p = 0.0006), esotropia (p = 0.002), abnormal head posture (p = 0.02) and motility defects (p = 0.003) compared to those with hydrocephalus developing during the first year of life. The etiology, number of shunt revisions and the size of the ventricles had no significant effect on any of the investigated variables. Children with hydrocephalus surgically treated before the age of one year commonly present orthoptic abnormalities. The etiology of hydrocephalus, number of shunt revisions and ventricle size seem to be of minor importance compared with the age of onset of hydrocephalus with regard to the risk for orthoptic abnormalities.

    ABSTRACT: To evaluate the correlation between the degree of anisometropia with depth of amblyopia and presence of stereopsis. A retrospective chart review of 119 patients treated during 1995-2004 was carried out. All patients had undergone a full ophthalmological examination. Inclusion criteria were: anisometropia >1 diopter (spherical and/or cylindrical), age at first examination between 2 and 8 years, no previous optical correction, absence of ocular and neurological disorders, absence of ocular motility disorders, and minimum follow-up of 2 years (mean 7.9 +/- 4.3). Optical correction was prescribed at first visit and, at a second visit, the need for patching or penalization was evaluated. The results show a correlation between the degree of anisometropia and visual acuity at first visit (p < 0.001). There were, however, several subjects with good levels of visual acuity despite considerable anisometropia, and also subjects where mild or moderate anisometropia was sufficient to induce a severe amblyopia. Compared to other types of anisometropia, anisomyopic patients appeared to have a higher degree of binocular vision recovery when corrected optically. First evaluation with the presence of good stereoacuity seems to be a prognostic indicator for amblyopic recovery. This study demonstrates the difficulty of developing a guideline for screening and treatment of anisometropia. Even though there seems to be a correlation between type and degree of anisometropia in a majority of patients, there is also a significant number of cases that do not follow this pattern. Another important observation is the presence of binocular vision at the first evaluation as a good prognostic indicator for visual recovery with optical correction alone, even without penalization therapy.

    ABSTRACT: To report the phenomenon of newly-noted binocular diplopia following vision improvement in patients with sensory strabismus secondary to keratoconus, and to document the effect of strabismus surgery on this diplopia. Retrospective institutional case series [1982--2005] of records coded with keratoconus and strabismus. Keratoconus patients with visual acuity that could not be improved, childhood strabismus, known reason for acquired strabismus (other than decreased vision from kerataconus), decreased vision from other ocular disease, monocular diplopia, failure of strabismus surgery, and/or less than six months follow-up after strabismus surgery were excluded. Although 103 medical records were identified, only seven met the strict inclusion criteria. All seven patients presented with gradual reduction in vision (not due to their strabismus), and none initially complained of diplopia. After intervention to improve visual acuity, six complained of constant binocular diplopia. This diplopia resolved after successful strabismus surgery. Postoperative Worth four-dot testing demonstrated suppression. Binocular diplopia, noted after intervention to improve visual acuity in our patients with strabismus secondary to long-standing uncorrected keratoconus, resolved after successful surgical alignment. Our patients may have developed suppression from uncorrected keratoconus before their sensory strabismus occurred.

    ABSTRACT: A 30-year-old male suffered an orbital trauma due to a traffic accident. At the Emergency Unit, the patient presented with avulsion of the upper left eyelid in the medial canthus, wounds in the lower eyelid and the inferior canaliculus, conjunctival laceration, proptosis and palpebral hematomas. The patient reported persistent diplopia. During the examination, exotropia and total absence of adduction were observed. Computerized tomography (CT) revealed a discontinuity at the left medial rectus. No orbital fractures were identifiable. The medial rectus was still attached to its anatomic insertion at the globe. The discontinuity was suggestive of laceration or rupture of this muscle at approximately 10-12 mm from its insertion. Surgical exploration revealed total rupture of the medial rectus at approximately 12 mm from its insertion. The posterior edge of the damaged muscle was found and sutured to its anterior edge with 6-0 polyglactin. The following day, the eyes were completely straight and the patient did not mention any signs of diplopia. Botulinum toxin injection into the ipsilateral lateral rectus was not necessary. After six months of follow-up, the patient still reported no diplopia. When muscular laceration is suspected after an orbital trauma, early CT is recommended. The only procedures that assure a significant recovery of the normal function of the eye are early muscle repair and avoidance, if possible, of transposition surgery.

    ABSTRACT: Smoking cannabis has been described to reduce acquired pendular nystagmus in MS, but its effect on congenital nystagmus is not known. To report the effect of smoking cannabis in a case of congenital nystagmus. A 19-year-old male with congenital horizontal nystagmus presented to the clinic after smoking 10 mg of cannabis. He claimed that the main reason for smoking cannabis was to improve his vision. At the next clinic appointment, he had not smoked cannabis for 3weeks. Full ophthalmologic examination and eye movement recordings were performed at each visit. Visual acuity improved by 3 logMar lines in the left eye and by 2 logMar lines in the right eye after smoking cannabis. The nystagmus intensities were reduced by 30% in primary position and 44%, 11%, 10% and 40% at 20-degree eccentricity to the right, left, elevation and depression, respectively, after smoking cannabis. Cannabis may be beneficial in the treatment of congenital idiopathic nystagmus (CIN). Further research to clarify the safety and efficacy of cannabis in patients with CIN, administered for example by capsules or spray, would be important.

    ABSTRACT: The ocular motility (OM) deficit in myasthenia has not been studied systematically. Anecdotal reports yield no consensus, with the pattern mimicking infranuclear, internuclear or supranuclear disorders. The current study defines the pattern of extra-ocular muscle (EOM) weakness at presentation for a group of newly diagnosed untreated ocular myasthenics (OMG). Cases referred to one consultant neurologist (RAM) between 1991 and 2001 were reviewed. EOM weaknesses were quantified using an established scoring method in 49 patients with OMG and 49 age- and sex-matched controls, to differentiate age-related changes from those secondary to myasthenia. Bilateral and multiple EOM weaknesses were typical. Only 6 cases mimicked isolated cranial nerve palsy. Weakness of the elevator muscles (superior rectus and inferior oblique) was common in both the OMG and control groups, but the amount of weakness was significantly greater for the myasthenia group (p = 0.003). All control subjects had a normal range of depression. EOM weaknesses for the control group were not confined to the older subjects. This is the first detailed analysis of EOM involvement in ocular myasthenia. The EOM weaknesses for the control group were invariably bilateral and symmetrical, mainly involving the superior recti. The preponderance for involvement of the elevator muscles is discussed.

    ABSTRACT: In the presence of both strabismus and cataract, it is always a dilemma whether to manage them separately or together. In this paper, the authors evaluate the results of combined strabismus and cataract surgery. The records of 50 patients were reviewed retrospectively. They were divided into two groups: those who developed strabismus first and cataract later (group 1, n = 17 patients) and those who developed cataract first and strabismus later (group 2, n = 33 patients). Motor alignment (less than 10 prism diopters) was achieved in 35.3% in group 1 and 75.8% in group 2. Visual success (20/40 or better) was attained in 70.6% in group 1 and 57.6% in group 2. In group 1, when the angle of deviation was more than 80 prism diopters, poor motor alignment was achieved (25%). Surgical success after one operation was achieved in the majority of all eyes that had combined surgery. In selected cases, combined strabismus and cataract surgery is a safe and effective procedure, optimizing the alignment of the visual axes, improving visual acuity, and minimizing the need for additional procedures.
