[Differential diagnostic criteria of accommodative disorders]

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• Myopia is a prevalent refractive error in children and adolescents.
• Accommodative disorders can significantly impact visual function and quality of life in myopic individuals.
• Accurate differentiation of accommodative disorders is crucial for effective management.

Purpose of the Study:

• To establish differential diagnostic criteria for accommodative disorders in myopic patients aged 6-23.
• To investigate accommodative insufficiency, habitual excess, and accommodative spasm.
• To provide a basis for precise diagnosis and targeted treatment strategies.

Main Methods:

• A cohort of 150 myopic patients (300 eyes) aged 6-23 years was studied.
• Patients were categorized into four groups: general myopia, accommodative insufficiency, habitual accommodative excess, and accommodative spasm.
• Comprehensive subjective and objective assessments of accommodation were performed for all participants.

Main Results:

• Differential diagnostic criteria for accommodative insufficiency, habitual excess, and spasm were identified.
• Distinct patterns in subjective and objective accommodation parameters were observed across the groups.
• The study successfully differentiated between the various types of accommodative disorders.

Conclusions:

• The identified criteria facilitate accurate differential diagnosis of accommodative disorders in young myopic individuals.
• This research contributes to a better understanding of functional vision anomalies in myopia.
• Precise diagnosis based on these criteria can lead to improved therapeutic outcomes for patients.
