The Ophthalmology Department diagnoses, monitors and treats conditions affecting vision and the anterior and posterior structures of the eye. Reduced or blurred vision, eye pain, redness, flashes of light, floaters, double vision and dry eye are common reasons for consultation. Because some eye diseases can progress without obvious symptoms, regular examinations are especially important for people with relevant risk factors.
What Is Ophthalmology?
An eye examination is much more than measuring a glasses prescription. Visual acuity, intraocular pressure, the cornea, lens, retina, optic nerve and, when necessary, eye movements and alignment are assessed as part of a broader evaluation.
Diabetes, hypertension, rheumatologic conditions and certain medications can affect eye health, so an ophthalmologist also considers the patient’s general medical history. In children, early detection of strabismus, amblyopia and refractive errors is particularly important for normal visual development.
What Symptoms or Concerns May Require an Appointment?
- Blurred or reduced vision
- Eye pain, stinging, burning, redness or dryness
- Flashes of light, newly developed floaters or a curtain-like shadow in the visual field
- Double vision or eye misalignment
- Reduced night vision or halos around lights
- Frequent changes in eyeglass prescription
- Eye monitoring because of diabetes or hypertension
- Eye deviation, closing one eye or changes in visual behavior in children
Which Conditions Are Evaluated and Treated?
- Refractive errors: Myopia, hyperopia, astigmatism and age-related difficulty focusing at near distances.
- Cataract: Clouding of the natural lens that can reduce vision.
- Glaucoma: A group of diseases that can damage the optic nerve and may progress silently.
- Retinal diseases: Diabetic retinopathy, age-related macular degeneration, retinal tears and retinal detachment.
- Corneal diseases: Keratoconus, infections and other corneal disorders.
- Ocular surface diseases: Dry eye and allergic or infectious conjunctivitis.
- Strabismus and amblyopia: Conditions requiring early assessment, especially in childhood.
- Eyelid and tear-duct conditions: Eyelid disorders, styes and lacrimal drainage problems.
How Does the Examination and Diagnostic Process Work?
The initial evaluation begins with a detailed medical history and eye examination. Tests are selected according to the ophthalmologist’s clinical question and the patient’s individual condition rather than performed routinely in every case.
- Visual acuity and refraction testing
- Slit-lamp examination
- Measurement of intraocular pressure
- Fundus and retinal examination
- Optical coherence tomography (OCT), visual-field testing, corneal topography or other advanced tests when indicated
Treatment and Service Areas
The following items describe common Ophthalmology services.
- Refraction assessment for eyeglasses and contact lenses
- Diagnosis and follow-up planning for cataract and glaucoma
- Evaluation of retinal diseases and referral or treatment as appropriate
- Treatment of dry eye and ocular surface disease
- Pediatric eye examination, strabismus and amblyopia assessment
- Eye surgery or laser procedures in suitable patients, according to the institution’s service scope
- Eye monitoring in diabetes and other systemic diseases
When Should You Seek Care?
Sudden vision loss, a curtain-like shadow over one eye, a sudden increase in flashes or floaters, chemical exposure, penetrating eye trauma or severe eye pain may require urgent ophthalmologic evaluation.
Frequently Asked Questions
How often should I have an eye examination?
The interval depends on age, use of corrective lenses, family history, systemic diseases such as diabetes and any existing eye condition. An ophthalmologist can recommend an individualized follow-up schedule based on risk factors.
Does high eye pressure always mean glaucoma?
No. Elevated intraocular pressure is an important glaucoma risk factor, but it does not by itself establish the diagnosis. The optic nerve, visual field and other findings must be assessed together.
Can cataracts be treated with medication?
Cataract is a loss of transparency in the natural lens of the eye, and there is no proven medication that removes an established cataract. Surgery may be considered when vision is impaired enough to affect daily life.
Are flashes of light and floaters important?
New or suddenly increased flashes and floaters can be associated with conditions such as a retinal tear that require prompt assessment. If a curtain-like shadow or vision loss is also present, urgent examination is especially important.
Why are eye examinations important in children?
The visual system develops during childhood. Detecting strabismus, significant refractive error or amblyopia early can improve the opportunity for effective treatment during the critical period of visual development.
Does computer use damage the eyes?
Screen use does not automatically cause permanent eye disease, but reduced blinking can contribute to dryness, headache and eye strain. Regular breaks, an appropriate viewing distance and suitable room lighting may help.
Are contact lenses suitable for everyone?
No. Corneal health, dry eye, hygiene habits and individual needs must be assessed. Lens type and wearing schedule should be selected according to professional advice.
Can diabetes affect the eyes?
Yes. Diabetes can damage retinal blood vessels and lead to diabetic retinopathy. Changes may begin before symptoms are noticed, so regular dilated retinal examinations are important.
