Modalities of reading acquisition in three siblings with infantile-onset saccade initiation delay (Cogan congenital ocular motor apraxia): A longitudinal study.

This study aims to ascertain the impact of congenital ocular motor apraxia (COMA), alternatively called infantile-onset saccade initiation delay (ISID), on reading acquisition. More specifically, the consequence of defective initiation of horizontal saccades during reading acquisition was investigated. Three siblings (A: male, 11y3m at the first time-point of testing (i.

Can a Specific Computed Tomography-Based Assessment Predict the Ophthalmological Outcome in Pure Orbital Floor Blowout Fractures?

The aim of this study was to determine the predictive value of a specific computed tomography (CT)-based assessment for the final functional ophthalmological outcome in pure orbital floor blowout fractures. Data of 34 consecutive patients with pure blowout fractures who had undergone a period of at least 6 months of medical and ophthalmological follow-up were analyzed. The following 3 CT scan-based parameters were included: area ratio of the fractured orbital floor (RF), maximum height of periorbital tissue herniation (MH), and a 4-grade muscular subscore (MSS) describing the inferior rectus muscle displacement relative to the orbital floor level.

Orthoptic Sequelae Following Conservative Management of Pure Blowout Orbital Fractures: Anecdotal or Clinically Relevant?

The aim of this study was to prospectively assess the prevalence of orthoptic anomalies following conservative management of pure blowout orbital fractures and to evaluate their clinical relevance. Clinical and radiologic data of patients with unilateral conservatively managed pure blowout orbital fractures with a minimum follow-up of 6 months were reviewed. Eligible patients were contacted and invited to undergo an extended ophthalmologic examination as follows: distance and near visual acuities, Hertel exophthalmometry, corneal light reflex (Hirschberg test), ductions and versions in the 6 cardinal fields of gaze, eye deviation with prisms and alternate cover test in all of the 9-gaze directions with Maddox rod, degrees of incyclo/excyclotorsion with right and left eye fixation, horizontal and vertical deviation with Hess-Weiss coordimetry, degree of horizontal/vertical and incyclo/excyclotorsion deviation with Harms wall deviometry, and vertical deviation with Bielschowsky head-tilt test.

Endogenous endophthalmitis in a patient with diabetes and foot osteomyelitis.

Endogenous endophthalmitis is a rare condition caused by the hematogenous spread of microorganisms from a remote infection site to the eye. Common predisposing conditions are intravenous drug abuse, diabetes, malignancy, immunosuppression, chronic renal failure, parenteral nutrition or invasive medical procedures. We describe a case of endogenous endophthalmitis in the setting of foot osteomyelitis in a patient with diabetes.

Primary leptomeningeal melanocytosis in a 10-year-old girl: a challenging diagnosis with a poor prognosis.

Primary leptomeningeal melanocytosis is rarely encountered in the pediatric population. Despite being considered a nonmalignant condition, it uniformly carries a poor prognosis given the ineluctable progression of meningeal infiltration. The case of a previously healthy 10-year-old girl who was first thought to suffer from recurrent hemiplegic migraine is reported.

MRI with fibre tracking in Cogan congenital oculomotor apraxia.

Background: Congenital ocular motor apraxia (COMA) occasionally shares with Joubert syndrome (JS) and related disorders (JSRDs) a peculiar malformation, the 'molar tooth sign' (MTS). In JSRDs, the absence of superior cerebellar peduncles (SCP) decussation is reported.

Objective: To investigate whether COMA demonstrates similar abnormal axonal pathways.

Ischemic retinopathy and neovascular proliferation secondary to shaken baby syndrome.

Background: Ocular lesions known to occur after shaken baby syndrome (SBS) are epiretinal, intraretinal, and subretinal hemorrhages, which are present in up to 100% of patients. Retinoschisis and retinal folds have also been described. We describe three patients with SBS who presented with tractional retinal detachments secondary to neovascular proliferation and discuss the role of ischemia at the retinal level.

Simulation of artificial vision: II. Eccentric reading of full-page text and the learning of this task.

Reading of isolated words in conditions mimicking artificial vision has been found to be a difficult but feasible task. In particular at relatively high eccentricities, a significant adaptation process was required to reach optimal performances [Vision Res. 43 (2003) 269].
