Onset and Factor Information for Accommodation Disorder

Onset information - Accommodation Disorder

Clinical onset of accommodation disorder

General information about accommodation disorder

Accommodation is the ability to produce a clear retinal image at varying distances.  This is achieved by alteration in the curvature of the lens of the eye through muscular contraction.  Accommodation disorder is caused by a disturbance in the oculomotor nerve function or ciliary muscle function.  (Accommodation disorder does not include presbyopia.)

Symptoms and signs of accommodation disorder

• The first sign or symptoms would be an inability to see clearly (focus on) objects at varying distances from the eye.
• Other symptoms may include blurred vision, double vision, eyestrain, headache, fatigue and difficulty concentrating (particularly while reading).

Establishing the clinical onset of accommodation disorder

It is likely that a person would seek medical attention once symptoms presented, and this would be recorded in doctors' notes.  However, if these records cannot be obtained, a reliable history of appropriate symptoms at a particular time generally will be accepted, unless there is contradictory evidence.  Seek medical advice if it is unclear whether the claimed symptoms at that time can be attributed to accommodation disorder.

Clinical worsening of accommodation disorder

There are no 'worsening factors' in the SOP for accommodation disorder.  The concept of 'clinical worsening' is therefore only relevant to the factor inability to obtain appropriate clinical management for accommodation disorder which applies only to material contribution to, or aggravation of, this eye disorder.  In this context, clinical worsening means permanent clinical worsening.

Worsening of accommodation disorder may be difficult to determine.  The symptoms of accommodation disorder vary widely, and an increase in symptoms may be due to the normal progression of the underlying pathology, rather than a worsening beyond its natural course.  Therefore, in most cases you will need to seek medical advice to determine whether the claimed symptoms at that time can be attributed to natural progression or to a worsening of the underlying pathology compared with the course which, given appropriate treatment, it should have taken.

Uncommon Contentions

Appropriate clinical management for accommodation disorder involves identification and treatment of the disease or circumstance which has led to the lesion affecting the oculomotor nerve or ciliary muscle.
