5. What are the different types of laser treatments used in Ophthalmology?

Various types of laser treatments are used in Ophthalmology to treat different eye conditions. Some common ones include:

• Laser Peripheral Iridotomy (LPI): Creates a small hole in the iris to improve fluid drainage and reduce intraocular pressure.
• Laser Trabeculoplasty (SLT): Stimulates the trabecular meshwork to improve fluid drainage, reducing intraocular pressure in patients with glaucoma.
• Laser Photocoagulation: Used to seal leaking blood vessels in conditions like diabetic retinopathy or macular degeneration.
• Laser Vitreolysis: Breaks up floaters in the vitreous humor, improving vision.
• Laser Iridotomy: Creates a hole in the iris to prevent angle closure glaucoma.

6. How do you calculate the IOL power using different formulas?

Calculating IOL power using different formulas is an important aspect of Ophthalmic Technology. Here are the steps involved:

• SRK/T Formula: SRK/T = A – 2.5 L + 0.9 K, where A is the axial length, L is the lens thickness, and K is the keratometry measurement.
• Holladay 2 Formula: Holladay 2 = A – 0.9 K – 0.25 K^2 + 0.2 A K.
• Haigis Formula: Haigis = A – 0.33 L + 0.06 K + 1.0.
• Barrett Universal II Formula: Barrett Universal II = A – 0.3 A^2 + 0.06 K + 0.74.

7. Explain the role of an Ophthalmic Technician in the diagnosis and management of Glaucoma

Ophthalmic Technicians play a crucial role in the diagnosis and management of Glaucoma:

• Tonometry: Measure intraocular pressure using various techniques like Goldmann applanation tonometry or non-contact tonometry.
• Visual Field Testing: Perform visual field tests to assess the extent of visual field loss.
• Gonioscopy: Examine the angle between the iris and cornea to determine the presence of any abnormalities that could lead to glaucoma.
• OCT Imaging: Capture cross-sectional images of the optic nerve and retinal nerve fiber layer to detect glaucoma-related changes.
• Assist in Laser Procedures: Assist the Ophthalmologist during laser treatments for glaucoma, such as SLT or LPI.

8. Describe the principles and procedure of Retinal Photography

Principles of Retinal Photography

• Uses a specialized camera to capture images of the retina.
• Provides a detailed view of the retina, optic nerve, and macula.

Procedure of Retinal Photography

• Pupils are dilated to allow a clear view of the retina.
• The patient’s head is positioned on a chin rest and forehead strap.
• The camera is focused on the retina, and a series of images are captured.
• The images are then analyzed to detect any abnormalities or signs of disease.

9. What are the indications and contraindications for Mydriasis?

Indications for Mydriasis

• Dilating the pupils for comprehensive eye exams.
• During certain ophthalmic procedures, such as cataract surgery or laser treatments.
• To treat certain eye conditions, such as uveitis or iritis.

Contraindications for Mydriasis

• Patients with a history of angle-closure glaucoma.
• Patients taking certain medications, such as monoamine oxidase inhibitors (MAOIs).
• Patients with corneal abrasions or other eye injuries.

10. How do you ensure patient safety during Ophthalmic Imaging procedures?

Ensuring patient safety during Ophthalmic Imaging procedures is paramount. Here are some key measures I take:

• Proper Equipment Handling: Handle equipment carefully to avoid any malfunctions or injuries.
• Infection Control: Follow strict sterilization and disinfection protocols to prevent infections.
• Patient Positioning: Position patients comfortably and securely to minimize discomfort and movement.
• Monitoring Patient Response: Observe patients closely during procedures and address any concerns promptly.
• Emergency Preparedness: Be prepared to handle emergencies, such as allergic reactions or equipment failures.
