Glaucoma

At Sri Nirwana Netralaya Eye Hospital, we understand the seriousness of glaucoma a silent, sight-threatening condition and are committed to providing advanced care to protect your vision and preserve your eye health.

• Primary Open-Angle Glaucoma: This is the most common form of glaucoma. It develops slowly over time and is often associated with gradual vision loss. The drainage canals in the eye become clogged over time, leading to increased intraocular pressure.
• Angle-Closure Glaucoma: This type occurs when the iris bulges forward, narrowing or blocking the drainage angle formed by the cornea and iris. This can cause a sudden increase in eye pressure, leading to an acute attack that requires immediate medical attention.
• Normal-Tension Glaucoma: Even with normal eye pressure, optic nerve damage can occur. The exact cause of this condition is not fully understood, but it may be related to decreased blood flow to the optic nerve.
• Congenital Glaucoma: This rare form of glaucoma is present at birth and is caused by abnormal development of the eye’s drainage system. Early intervention is crucial for preserving vision.
• Secondary Glaucoma: This type of glaucoma can develop as a result of another eye condition, injury, or the use of certain medications like corticosteroids.

Diagnosis and Evaluation At Sri Nirwana Netralaya, we use state-of-the-art diagnostic tools to detect glaucoma in its earliest stages. Our comprehensive eye exams include:

• Tonometry: This test measures the pressure inside your eye. Elevated intraocular pressure is a significant risk factor for glaucoma.
• Ophthalmoscopy: This test allows our ophthalmologists to examine the shape and color of the optic nerve for signs of damage.
• Perimetry (Visual Field Test): This test maps your peripheral vision to detect any vision loss associated with glaucoma.
• Gonioscopy: This test helps determine whether the angle where the iris meets the cornea is open or closed, which is essential for diagnosing different types of glaucoma.
• Optical Coherence Tomography (OCT): This advanced imaging technique provides detailed images of the optic nerve and retina, helping to detect early signs of glaucoma.

Treatment Options for Glaucoma At Sri Nirwana Netralaya, we offer a range of treatment options tailored to the type and severity of glaucoma:

• Medications
  • Eye Drops: Prescription eye drops are often the first line of treatment for glaucoma. They work by either reducing the production of fluid in the eye or increasing its outflow, thereby lowering intraocular pressure.
  • Oral Medications: In some cases, oral medications may be prescribed to further decrease eye pressure.
• Laser Therapy
  • Selective Laser Trabeculoplasty (SLT): SLT is a laser treatment used to open up the drainage channels in the eye, helping to lower intraocular pressure. It is often used when eye drops alone are not sufficient.
  • Laser Peripheral Iridotomy: This procedure is primarily used to treat angle-closure glaucoma. A small hole is made in the iris to improve fluid drainage and reduce pressure.
• Surgical Procedures
  • Trabeculectomy: This is the most common surgical procedure for glaucoma. It involves creating a new drainage pathway to help fluid escape from the eye, reducing intraocular pressure.
  • Glaucoma Drainage Devices: Also known as tube shunts, these devices are implanted to help drain fluid from the eye when other treatments have not been successful.
  • Minimally Invasive Glaucoma Surgery (MIGS): MIGS procedures are less invasive than traditional glaucoma surgeries and are often used in conjunction with cataract surgery. They aim to lower eye pressure with fewer complications and quicker recovery times.
• Cyclophotocoagulation
  • Endoscopic Cyclophotocoagulation (ECP): This procedure uses a laser to target and reduce the production of fluid in the eye, lowering intraocular pressure. It is often used when other treatments have not been effective.
