What are the common special eye examinations?
1. Visual field examination: Used to assess visual field extent and defects, particularly in patients with glaucoma.
2. Fundus photography: Used to capture images of the retina and optic disc, aiding in the diagnosis of retinal diseases and other fundus diseases.
3. Optical coherence tomography (OCT): Used to obtain high-resolution cross-sectional images of the retina and optic nerve, for the diagnosis and monitoring of conditions such as macular degeneration and diabetic retinopathy.
4. Corneal topography: Used to measure the shape and curvature of the cornea, particularly useful for preoperative evaluation before refractive surgery.
5. Intraocular pressure measurement: Used to measure intraocular pressure, aiding in the diagnosis and management of glaucoma.
What are the significance and functions of special eye exams?
1. Early disease detection: Eye diseases such as glaucoma, macular degeneration, and diabetic retinopathy can be detected early, allowing for timely treatment.
2. Assessing overall health: Changes in the fundus can reflect systemic diseases such as hypertension, diabetes, and arteriosclerosis.
3. Monitoring treatment effectiveness: This is used to monitor the progress and effectiveness of treatment, especially for patients with chronic eye diseases.
4. Preventing vision loss: Early detection and intervention of fundus lesions can help prevent irreversible vision loss.
5. Early detection of the development and severity of myopia in adolescents and children can help protect their healthy growth.
