Outcome Measures
Primary Outcomes (1)
The accuracy of referral
The accuracy of referral of AI model will be calculated with the decisions based on the portable slit-lamp images with reference to the ground truth.
Baseline
Secondary Outcomes (1)
The accuracy of cataract diagnosis
Baseline
Study Arms (2)
Referral group
The patients with severe cataracts in this group need a referral to a higher-level hospital for further treatment.
Observation group
The patients with mild cataracts or transparent lenses in this group do not need a referral to a higher-level hospital for further treatment and keep regular examinations.
Interventions
The enrolled patients will undergo portable slit-lamp photography with and without mydriasis and receive traditional slit-lamp photography for comparison.
Eligibility Criteria
The prospective population aged 0 to 100 with or without senile cataracts and received ocular examination.
You may qualify if:
- to 100 years old
You may not qualify if:
- (1) History of eye disease except for age-related cataracts (2) History of eye trauma or eye surgery (3) Unable to cooperate with ophthalmology and general examination (4) Individuals with incomplete information (5) Unwilling to participate in this study
