Laser Eye Surgery and Glaucoma
11th December, 2012
Glaucoma is an eye disorder marked by unusually high pressure within the eyeball that leads to damage of the optic disc. There are various types of Glaucoma with open angle Glaucoma being the most common form. Open angle Glaucoma is caused by the slow clogging of the drainage canals, resulting in increased eye pressure. This means there is a wide and open angle between the iris and the cornea. Open angle Glaucoma develops slowly and is a lifelong condition. Other types of Glaucoma include: normal tension Glaucoma which means the optic nerve is damaged even though the eye pressure is not very high, congenital Glaucoma which occurs in babies when there is incorrect or incomplete development of the eye’s drainage canals, secondary Glaucoma, pigmentary Glaucoma, pseudoexfoliative Glaucoma, traumatic Glaucoma, neovascular Glaucoma and irido corneal endothelial syndrome. Please consult with a specialist to determine whether the type of Glaucoma you have can be treated by surgery.
There are several different types of laser eye surgery used to treat Glaucoma. The type of surgery and the treatment you will require will depend upon the form of Glaucoma and how severe the condition is. Once you have decided that laser surgery is the right option for you, the surgeon who will be at your initial assessment will be able to talk you through the option which will fit your specific needs.
There are several treatments available to treat Glaucoma:
• Selective Laser Trabeculoplasty is used to treat primary open angle Glaucoma. This method of treatment treats specific cells selectively.
• Argon Laser Trabeculoplasty is used for the treatment of primary open angle Glaucoma also. With this type of surgery, the laser opens fluid channels of the eye which ensure the drainage system works better. Although, in many cases, medication will still be needed.
• Laser Peripheral Iridotomy is used to treat narrow angle and narrow angles Glaucoma. Narrow angle Glaucoma occurs when the angle between the iris and the cornea in the eye is too small. This causes the iris to block fluid drainage, increasing inner eye pressure. With this type of surgery, a small hole is made in the iris, allowing the fluid to drain.
There are many benefits of having laser eye surgery in order to treat Glaucoma. Glaucoma laser surgery helps to lower intraocular pressure in the eye. The length the pressure stays low depends upon the type of surgery performed, the type of Glaucoma, the patient’s age, the patient’s race and several other factors. If the surgery does not manage to control the pressure to an acceptable level, then surgery can be repeated.
Medication to keep eye pressure low will usually still be needed after eye laser treatment, however, the amount of medication will be significantly lowered. When it comes to recovery time following surgery for Glaucoma, the recovery time is the same as typical eye surgery for eye conditions such as myopia. Patients are expected to recover by the next day and many patients will go back to work the morning after surgery.
