Glaucoma Services: Investigations, Lasers And Surgery

Glaucoma is a group of eye diseases that can cause irreversible vision loss if left untreated. Fortunately, advancements in glaucoma services have significantly improved the diagnosis and management of this condition.

Glaucoma Investigations:
  1. Tonometry: Tonometry measures the intraocular pressure (IOP) to determine if it is within the normal range or elevated, which is a key indicator of glaucoma risk.
  2. Visual Field Testing: This test assesses the extent and quality of a person’s peripheral vision, detecting any loss that may indicate glaucoma damage.
  3. Optical Coherence Tomography (OCT): OCT is used to assess the thickness of the optic nerve fiber layer and the health of the retinal nerve fiber layer, providing valuable information for diagnosing and monitoring glaucoma.
  4. Gonioscopy: Gonioscopy allows examination of the drainage angle of the eye, helping determine the type and severity of glaucoma.
  5. Pachymetry: This test measures the thickness of the cornea, as corneal thickness can influence intraocular pressure readings.
Advantages of Glaucoma Investigations:
  1. Early Detection: Glaucoma investigations aid in the early detection of the disease, allowing for timely intervention and preventing further vision loss.
  2. Accurate Diagnosis: These investigations provide ophthalmologists with important data to accurately diagnose the type and stage of glaucoma, enabling personalized treatment plans.
  3. Monitoring Progression: Regular glaucoma investigations help monitor disease progression and determine the effectiveness of treatment interventions.
  4. Customized Treatment: Based on investigation results, ophthalmologists can tailor treatment plans to address specific glaucoma characteristics, optimizing outcomes for each patient.
Glaucoma Lasers:
  1. Selective Laser Trabeculoplasty (SLT): SLT uses laser energy to target and improve the function of the eye’s drainage system, reducing intraocular pressure.
  2. Argon Laser Trabeculoplasty (ALT): ALT is an older laser treatment that creates tiny burns on the trabecular meshwork to enhance fluid drainage.
  3. Laser Peripheral Iridotomy (LPI): LPI creates a small hole in the iris, allowing for better fluid flow and reducing the risk of angle-closure glaucoma.
Advantages of Glaucoma Lasers:
  1. Minimally Invasive: Laser treatments are generally non-invasive or minimally invasive procedures that can be performed in an outpatient setting, reducing the risks associated with traditional surgeries.
  2. Lowering Intraocular Pressure: Glaucoma lasers target the eye’s drainage system, improving fluid outflow and lowering intraocular pressure.
  3. Fewer Side Effects: Laser treatments typically have fewer side effects compared to traditional glaucoma surgeries, such as reduced risk of infection or bleeding.
Glaucoma Surgeries:
  1. Trabeculectomy: Trabeculectomy creates a new drainage channel to lower intraocular pressure by diverting fluid from the eye.
  2. Tube Shunt Surgery: Tube shunt surgery involves implanting a small tube to facilitate fluid drainage from the eye and reduce intraocular pressure.
  3. Minimally Invasive Glaucoma Surgery (MIGS): MIGS encompasses a range of procedures that use tiny devices or implants to improve fluid outflow and lower intraocular pressure.
Advantages of Glaucoma Surgeries:
  1. Effective Pressure Reduction: Glaucoma surgeries aim to lower intraocular pressure effectively, reducing the risk of further damage to the optic nerve.
  2. Long-Term Management: Surgical interventions can provide long-term control of intraocular pressure, potentially reducing the need for daily eye drops.
  3. Improved Quality of Life: By reducing intraocular pressure and preserving vision, glaucoma surgeries can enhance a patient’s overall quality of life.
