“…Nistagmus infantil biasanya ditemukan saat usia 2 sampai 3 bulan, nistagmus pada kelainan herediter dapat ditemukan saat lahir. 3 Nistagmus infantil motorik atau sindrom nistagmus infantil (SNI) merupakan tipe nistagmus infantil yang paling sering, diikuti nistagmus yang berkaitan dengan penyakit okular. 4 EPIDEMIOLOGI Nash, et al, menggunakan data Rochester Epidemiology Project di Amerika Utara, menemukan 71 nistagmus infantil selama 30 tahun, insidens setiap tahun 6,72 per 100.000 usia di bawah 19 tahun (95% CI 5,28) dan 59,2% adalah laki-laki.…”

“…Jika pasien nistagmus infantil lebih jelas melihat saat siang hari daripada malam hari, dapat dicurigai adanya rod-cone dystrophy atau congenital stationary night blindness (CSNB). 3 Pasien nistagmus infantil dengan riwayat keluarga hipopigmentasi kulit dapat dicurigai menderita albinisme okulokutaneus. 3 Manifestasi oscilopsia (sensasi melihat benda statis seolah-olah bergerak) jarang ditemukan pada nistagmus infantil.…”

Alasannya masih belum jelas, diduga karena impuls saraf motorik eferen yang dikirim untuk otot ekstraokuler juga dikirim ke area sensorik dan motorik otak yang lain.…”

<p>Nistagmus berasal dari bahasa Yunani, nystagmos yang berarti mengangguk dan kata nystazein yang berarti mengantuk. Nistagmus merupakan gerakan involunter dan osilasi ritmik mata yang dapat fisiologis ataupun patologis. Angka kejadian nistagmus diperkirakan 24 per 10.000 populasiumum. Nistagmus infantil motorik atau sindrom nistagmus infantil (SNI) merupakan tipe nistagmus infantil yang paling sering.Onset dan manifestasi klinis dapat membantu diagnosis; pemeriksaan penunjang biasanya dilakukan pada usia diatas 6 bulan. Beberapa terapi di antaranya terapi optikal, terapi obat, terapi pembedahan untuk meningkatkan tajam penglihatan dan terapi pembedahan untuk merelokasi Null Zone ke posisi primer.</p><p>Nystagmus, adopted from Greek nystagmos, means nodding and nystazein means sleepy. Nystagmus is involuntary movement and oscilation of the eye;may be physiologic or pathologic. Th incidence is about 24 in 10.000 population. Motor infantile nystagmus or infantile nystagmus syndrome is the most common type of infantile nystagmus. Diagnosis is based on onset and clinical manifestations; additional examination is for baby older than 6 months. Therapy is to improve visual acuity and surgery to relocate Null Zone to primary position.</p>

“…Children with nystagmus often have refractive errors such as astigmatisms, myopia or hyperopia, given prescription can enable better development of the visual system and with improvement of fixation and fovealization nystagmus can dampen. In the cases of very poor visual acuity, some magnifying visual aids can be helpful [32].…”

Nystagmus is an involuntary rhythmical movement of the eyes. The cause of nystagmus is a disruption in the afferent, central or efferent parts of the eye movement system. If it happens in the first few months of life during the sensitive period of visual development, it is most often a case of infantile nystagmus. On the other hand, the majority of nystagmus in adult age is caused by some neurological disorder, and it is usually called acquired nystagmus. The important role of an ophthalmologist is to recognize the origin of nystagmus. Acquired forms are usually caused by some neurological disorders and do not belong in our field of treatment. However, most of the nystagmus types in a child's age require ophthalmological treatment. When we have a child with nystagmus, we have to enable the development of the visual system and help fixation and fovealization by the dampening of nystagmus. If the reason of nystagmus is of ocular origin, we have to treat the underlying disease. Optical treatment by glasses, contact lenses or magnifying devices is usually reasonable. In some cases when the patient has abnormal head posture, it is possible to treat nystagmus by surgery. Some medications are used in several types of nystagmus as well as some new developing treatments.

“…In FMNS, the ET and nystagmus are coincidental, whereas in nystagmus blockage syndrome the null zone in adduction precedes and causes ET. Accordingly, the ET increases as the nystagmus dampens, and decreases with increasing nystagmus [ 7 ].…”

Effects of extraocular muscle surgery in children with monocular blindness and bilateral nystagmus

BackgroundMonocular infantile blindness may be associated with bilateral horizontal nystagmus, a subtype of fusion maldevelopment nystagmus syndrome (FMNS). Patients often adopt a significant anomalous head posture (AHP) towards the fixing eye in order to dampen the nystagmus. This clinical entity has also been reported as unilateral Ciancia syndrome. The aim of the study was to ascertain the clinical features and surgical outcome of patients with FMNS with infantile unilateral visual loss.MethodsIn this retrospective case series, nine consecutive patients with FMNS with infantile unilateral visual loss underwent strabismus surgery to correct an AHP and/or improve ocular alignment. Outcome measures included amount of AHP and deviation at last follow-up.ResultsEye muscle surgery according to the principles of Kestenbaum resulted in a marked reduction or elimination of the AHP. On average, a reduction of AHP of 1.3°/mm was achieved by predominantly performing combined horizontal recess-resect surgery in the intact eye. In cases of existing esotropia (ET) this procedure also markedly reduced the angle of deviation. A dosage calculation of 3 prism diopters/mm was established.ConclusionsWe advocate a tailored surgical approach in FMNS with infantile unilateral visual loss. In typical patients who adopt a significant AHP accompanied by a large ET, we suggest an initial combined recess-resect surgery in the intact eye. This procedure regularly led to a marked reduction of the head turn and ET. In patients without significant strabismus, a full Kestenbaum procedure was successful, while ET in a patient with a minor AHP was corrected by performing a bimedial recession.
