Latest work with IntechOpen by Ivana Mravicic

This book explains why, when, and how to treat eye motility disorders. It starts with a discussion of the general principles of eye motility and its importance in creating binocular single vision with depth perception. It also reviews the most important parts and functions of the sensory and motor eye motility system for those new to the field of ophthalmology. The book also describes different types of strabismus and the treatment for each type. Special care is taken to explain the difference between causes, diagnostics, and treatment of eye motility disorders in children with immature visual system and, on the other side, in adult cases when development is already finished. It describes the steps of orthoptic assessment, with a special interest in tests for binocularity. It also presents different conservative treatment possibilities, including glasses, prisms, orthoptic exercise, Botox, and so on. In cases where conservative treatment is not enough, surgery is the method of choice. The choice of surgical treatment depends on the age of the patient, the type of strabismus, and the muscle involved. The book thus presents the principles of surgeries along with explanations and figures.

Nystagmus

By Ivana Mravicic, Selma Lukacevic, Maja Bohac, Maja Pauk-Gulic and Vlade Glavota

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.

Treatment of Paralytic Eye Motility Disorders

By Ivana Mravicic, Alma Biscevic, Melisa Ahmedbegović Pjano, Ivona Petrovska, Anja Shumejko and Nina Ziga

Paralytic strabismus is caused by paresis or paralysis of one or more extraocular muscles that are innervated by cranial nerve lll, IV and Vl. They are characterized by squinting angle that depends on the direction of the gaze and the fixating eye. Typically, the angle is greater in the field of affected muscle, and when the patient is fixing with the affected eye. While younger children in some cases can suppress double vision, older children and adults with acquired paralytic strabismus usually have diplopia, which they try to avoid by compensatory head posture. Some types of paralytic strabismus can be congenital but it is important to diagnose acquired paralytic strabismus that can be caused by some neurological or systemic disorders and requires further investigation. Treatment of the paralytic strabismus is challenging, and despite the multiple surgeries, results can be disappointing.
