Study Notes

Surgical Procedures

Cataract Surgery
- Removal of the cloudy lens.
- Intraocular lens (IOL) implantation.
LASIK (Laser-Assisted In Situ Keratomileusis)
- Refractive surgery to correct myopia, hyperopia, and astigmatism.
- Involves reshaping the cornea using a laser.
Glaucoma Surgery
- Trabeculectomy: Creates a new drainage pathway for fluid.
- Tube shunt: Involves placing a small tube to help drain fluid.
Retinal Surgery
- Vitrectomy: Removal of the vitreous gel to treat retinal detachment or other conditions.
- Laser photocoagulation: Uses laser to treat retinal tears or diabetic retinopathy.
Corneal Transplant
- Replacement of a damaged cornea with donor tissue.
- Indicated for conditions like keratoconus or corneal scarring.

Common Eye Diseases

Cataracts
- Clouding of the lens leading to vision impairment.
- Common in older adults; can affect quality of life.
Glaucoma
- Group of diseases causing optic nerve damage, often associated with increased intraocular pressure.
- Can lead to irreversible blindness if untreated.
Age-related Macular Degeneration (AMD)
- Progressive degeneration of the central retina.
- Two forms: dry (more common) and wet (more severe).
Diabetic Retinopathy
- Damage to retinal blood vessels due to diabetes.
- Can cause vision loss; requires regular eye examinations.
Dry Eye Syndrome
- Insufficient tear production or poor-quality tears.
- Symptoms include irritation, redness, and blurred vision.

Diagnostic Techniques

Visual Acuity Test
- Measures the sharpness of vision using an eye chart.
Tonometry
- Measures intraocular pressure to screen for glaucoma.
Slit-Lamp Examination
- Provides a magnified view of the eye structures.
- Useful for diagnosing cataracts, corneal injuries, and other conditions.
Fundoscopy (Ophthalmoscopy)
- Allows visualization of the retina and optic nerve.
Optical Coherence Tomography (OCT)
- Non-invasive imaging technique to obtain high-resolution cross-sectional images of the retina.
Visual Field Testing
- Assesses peripheral vision and detects blind spots or vision loss patterns.

Surgical Procedures

Cataract Surgery involves the removal of the cloudy lens and implantation of an intraocular lens (IOL) to restore clear vision.
LASIK is a refractive surgery that corrects myopia, hyperopia, and astigmatism by reshaping the cornea with a laser.
Glaucoma Surgery includes trabeculectomy, which creates a new drainage pathway for fluid, and tube shunt surgery, where a small tube is inserted to facilitate drainage and reduce intraocular pressure.
Retinal Surgery options comprise vitrectomy, for removing the vitreous gel to treat retinal detachment, and laser photocoagulation, which employs laser technology to address retinal tears and diabetic retinopathy.
Corneal Transplant replaces a damaged cornea with donor tissue, suitable for conditions such as keratoconus and corneal scarring.

Common Eye Diseases

Cataracts cause clouding of the lens, commonly seen in older adults, leading to decreased vision quality and potential blindness if untreated.
Glaucoma refers to a group of conditions resulting in optic nerve damage, often linked to increased intraocular pressure, which can cause irreversible blindness without intervention.
Age-related Macular Degeneration (AMD) is characterized by the progressive degeneration of the central retina, with two types: dry AMD (more prevalent) and wet AMD (more severe).
Diabetic Retinopathy results from damage to retinal blood vessels in individuals with diabetes and can lead to significant vision loss, making regular eye exams essential.
Dry Eye Syndrome involves insufficient tear production or the presence of poor-quality tears, leading to irritation, redness, and blurred vision.

Diagnostic Techniques

Visual Acuity Test measures vision sharpness using an eye chart to determine clarity and detail of sight.
Tonometry assesses intraocular pressure, essential for screening and diagnosing conditions like glaucoma.
Slit-Lamp Examination provides a detailed, magnified view of eye structures, aiding in the diagnosis of cataracts and corneal injuries.
Fundoscopy (Ophthalmoscopy) enables visualization of the retina and optic nerve, crucial for diagnosing various eye diseases.
Optical Coherence Tomography (OCT) is a non-invasive imaging technique yielding high-resolution cross-sectional images of the retina, helping in diagnosing retinal conditions.
Visual Field Testing evaluates peripheral vision, detecting blind spots and patterns of vision loss, contributing to comprehensive eye assessments.

Surgical Procedures

Cataract Surgery: Involves removing a cloudy lens and replacing it with an intraocular lens (IOL). Common methods include phacoemulsification and extracapsular cataract extraction.
Laser Surgery:
- LASIK: Reshapes the cornea to correct refractive errors such as myopia, hyperopia, and astigmatism.
- PRK: An alternative procedure for patients with thin corneas that removes the outer layer of the cornea.
Glaucoma Surgery:
- Trabeculectomy: Establishes a new drainage pathway for aqueous humor to lower intraocular pressure.
- Tube Shunt Surgery: Involves inserting a tube to facilitate fluid drainage and reduce eye pressure.
Retinal Surgery:
- Vitrectomy: Removes the vitreous gel to treat conditions like retinal detachment.
- Laser Photocoagulation: Utilizes laser technology to seal retinal blood vessel leaks and repair retinal tears.

Common Eye Diseases

Cataracts: Characterized by clouding of the lens, leading to vision impairment; risk factors include aging, genetics, diabetes, and exposure to UV light.
Glaucoma: A collection of diseases that harm the optic nerve, typically associated with elevated intraocular pressure; includes open-angle and angle-closure types.
Age-related Macular Degeneration (AMD): Causes central vision loss through degeneration of the macula and is classified into dry (atrophic) and wet (neovascular) types.
Diabetic Retinopathy: Results from diabetes-related damage to the retina, potentially leading to blindness; classified into non-proliferative and proliferative stages.
Conjunctivitis: Inflammation of the conjunctiva, commonly known as pink eye, which can be viral, bacterial, or due to allergies.

Diagnostic Techniques

Visual Acuity Test: Evaluates sharpness of vision using an eye chart.
Tonometry: Measures intraocular pressure as an indicator of glaucoma risk.
Fundoscopy: Allows examination of the eye's interior, including the retina and optic nerve.
Optical Coherence Tomography (OCT): Produces detailed cross-sectional images of the retina, assisting in diagnosing retinal conditions.
Fluorescein Angiography: Involves injecting a dye to visualize retinal blood vessels, pivotal for diagnosing diabetic retinopathy and AMD.
Perimetry: Assesses the entire field of vision to identify blind spots or scotomas, crucial for glaucoma evaluation.
