Essential Ophthalmology Tools: From Retinoscope to OCT
Ophthalmologists use specialized instruments for examination and treatment:
- Retinoscope: Measures refractive error (nearsightedness/farsightedness).
- Ophthalmoscope: Examines retina, optic nerve, blood vessels.
- Slit lamp: Magnifies anterior eye structures.
- Tonometer: Measures intraocular pressure (glaucoma screening).
- Autorefractor: Automated refractive error measurement.
- A-scan: Measures eye length (contact lens/IOL planning).
- B-scan: Cross-sectional ultrasound imaging.
- Optomap: Panoramic retinal imaging.
- IOLMaster: Biometry for cataract surgery lens selection.
- OCT (Ocular Coherence Tomography): Light-wave cross-sections of retina/optic nerve for glaucoma, macular degeneration, diabetic retinopathy.
