OPHTHALMOLOGY NOTES
Common symptoms of ophthalmology
1. Vision Changes:
Blurred vision
Double vision (diplopia)
Sudden vision loss (partial or complete)
Difficulty seeing at night (nyctalopia)
Light sensitivity (photophobia)
2. Eye Discomfort & Pain:
Eye redness
Burning or itching sensation
Foreign body sensation
Eye strain or fatigue
Common optical examination
1. Visual Acuity Test
Snellen Chart – Measures how well a patient can see at a distance.
2. Pupil Examination
Direct and Consensual Light Reflex – Tests pupillary reaction to light.
Swinging Flashlight Test (RAPD Test) – Detects optic nerve dysfunction.
3. Intraocular Pressure Measurement
Tonometry (Goldmann, Non-contact, or Schiotz) – Measures eye pressure for glaucoma screening.
4. Slit Lamp Examination
Uses a microscope and high-intensity light to inspect the cornea, lens, anterior chamber, and other anterior eye structures.
5. Fundoscopy (Ophthalmoscopy)
Direct Ophthalmoscopy – Quick retina and optic disc evaluation.
Indirect Ophthalmoscopy – Provides a wider and more detailed retinal view.
6. Color Vision Testing
Ishihara Test – Detects red-green color blindness.
7. Visual Field Testing
Confrontation Visual Field Test – Basic assessment for peripheral vision loss.
Automated Perimetry (Humphrey or Goldmann) – More detailed mapping of visual field defects.
8. Fluorescein Staining & Tear Film Tests
Fluorescein Staining – Detects corneal abrasions, ulcers, or dry eye.
Abnormal Eye Appearance or Movement
Swelling around the eyes
Droopy eyelids (ptosis)
Misaligned eyes (strabismus)
Involuntary eye movement (nystagmus)
Discharge & Tearing Issues:
Excessive tearing (epiphora)

Flashes, Floaters & Other Visual Disturbances:
Seeing flashes of light
Floaters (small spots moving in vision)
Halos around lights

Important Notes
Steroids should not be used in viral or fungal infections unless prescribed by an ophthalmologist.
Glaucoma medications are typically lifelong treatments.
Antibiotics should be used for the full duration prescribed to prevent resistance.
Anesthetics are for diagnostic/procedural use only and should not be used frequently as they can damage the cornea.

3. Corneal Surgery
Penetrating Keratoplasty (Corneal Transplant) – Full-thickness corneal replacement for severe corneal disease.

Laser Photocoagulation – Laser treatment to seal retinal tears or treat diabetic retinopathy.
5. Oculoplastic & Reconstructive Surgery
Dacryocystorhinostomy (DCR) – A procedure to create a new tear drainage pathway in blocked tear ducts.
Enucleation/Evisceration – Removal of the eye in cases of severe trauma or cancer.
6. Refractive Surgery
LASIK (Laser-Assisted in Situ Keratomileusis) – Laser surgery to correct refractive errors like myopia and hyperopia.
PRK (Photorefractive Keratectomy) – An alternative to LASIK for corneal reshaping.
7. Other Minor Ophthalmic Procedures
