Ophthalmologists are medical doctors who specialize in eye and vision care. They diagnose and treat a wide range of conditions, and they use advanced medical and surgical techniques to help patients. During an exam, these specialists utilize precise diagnostic tools to pinpoint issues within the delicate structures of the eye. Here is more information about how eye doctors diagnose and treat some common eye conditions:
Treating Ocular Cataracts
When proteins in the lens break down, they clump together to form a cataract. Ophthalmologists identify this clouding during a comprehensive eye exam. A slit-lamp examination magnifies the eye, and a retinal exam allows the doctor to see the back of the eye.
Surgery is the primary mode of correcting cataracts, and there are several options of lenses to choose from for this procedure. The surgeon removes the cloudy lens. After the surgeon removes the lens, they replace it with an intraocular lens, or IOL, to restore clear vision. This new lens may reduce your reliance on glasses, but you may still need your glasses for certain activities like reading.
Managing Glaucoma Progression
Because glaucoma presents few early symptoms, regular screenings help to protect against vision loss. Doctors measure intraocular pressure using tonometry. High pressure signals a problem, so the physician checks the optic nerve for signs of damage.
Treatment focuses on lowering eye pressure. Prescription eye drops decrease fluid production, or they help fluid drain from the eye more effectively. If medications fail to control the pressure, the doctor might recommend laser therapy or traditional surgery.
Addressing Macular Degeneration
Age-related macular degeneration, or AMD, affects central vision, and it comes in two primary forms. Dry AMD involves the thinning of the macula. Wet AMD occurs when abnormal blood vessels grow under the retina and leak fluid.
As the doctor diagnoses this condition, they look for yellow deposits called drusen. An Amsler grid tests for wavy lines in central vision. Optical coherence tomography, or OCT, scans the retina, and fluorescein angiography highlights leaking blood vessels.
Treatment depends on the type of AMD present. There is no cure for dry AMD, but specific vitamin supplements may slow its progression in intermediate stages. Because wet AMD is more aggressive, medications injected into the eye help stop the growth of abnormal blood vessels.
Treating Diabetic Retinopathy
High blood sugar levels damage blood vessels in the retina, which leads to diabetic retinopathy. A dilated eye exam reveals these changes. The doctor searches for swelling, and they may use special imaging to check for leakage.
Doctors employ several methods to treat this condition. Common interventions include:
- Injections to block abnormal vessel growth
- Laser treatment to seal leaking vessels
- Vitrectomy to remove blood from the vitreous gel
Managing diabetes controls the disease, but advanced cases may require surgical intervention. Early detection allows ophthalmologists to preserve vision before permanent damage occurs.
