purpose: to present a case of spontaneous resolution of essential esotropia case report: a 22-month-old girl presented with eye deviation since the age of 4 month. in the first examination, visual acuity of both eyes was c+s+m+. the patient had 35 prism diopters of alternative esotropia in primary position and also bilateral inferior oblique overaction (iooa). there was no significant refractiv...

BACKGROUND Latent nystagmus is a horizontal binocular oscillation that is evoked by unequal visual input to the 2 eyes. It develops primarily in humans with congenital esotropia. OBJECTIVE To investigate the interrelationship between latent and peripheral vestibular nystagmus and their corollary neuroanatomical pathways. METHODS Examination of subcortical neuroanatomical pathways producing ...

Latent/manifest latent nystagmus (LMLN) is a specific type of infantile nystag­ mus that occurs subsequent to strabismus in some patients.1.2 The amplitude of LMLN usually follows Alexander's law, increasing as the fixating eye moves into abduction and decreasing in adduction. 1 The slow phases of LMLN may be either linear or of decreasing velocity in the same patient. 3 Depending on the slow-p...

SUMMARY We used ocular motility recordings to identify the characteristics of a rare combination of conjugate, horizontal jerk, and pendular nystagmus in a 9-year-old boy. The clinical diagnoses were amblyopia, left esotropia, congenital nystagmus, and an apparently uniocular pendular nystagmus that mimicked spasmus nutans. Ocular motility recordings revealed an unusual latent/manifest latent n...

Abnormalities of foveal smooth pursuit and the monocular optokinetic response (OKR) have often been reported in subjects with latent nystagmus (LN) and manifest latent nystagmus (MLN). This abnormality typically takes the form of a monocular asymmetry with a deficit in the response to nasal-to-temporal (N-T) motion in the visual field. Previous studies have each presented different interpretati...

Manifest latent nystagmus (MLN) was identified in 31 patients by accurate eye movement records. All the patients had horizontal tropias, and the nystagmus fast phases were always in the direction of viewing eye. The slow phases of MLN are decreasing-velocity exponentials while those of the jerk form of congenital nystagmus (CN) are increasing velocity exponentials. Several subjects who were bel...
