What are the symptoms of glaucoma?
Symptoms of chronic or acute glaucoma include trouble focusing vision, sensation of a blind area (Scotoma), headaches associated with exercise, halos around light and even pain in the eye, particularly when associated with smoky vision. Very often there are no symptoms and hence a routine eye check up after the age of 40 is usually advisable to rule out glaucoma.
What are the types?
Glaucoma could be the open angle type which is usually without symptoms and hence gets diagnosed only in the late stages. In the angle closure type, the eye pressure rises acutely due to a sudden block in the drainage system. Glaucoma may also occur in children (congenital glaucoma) after trauma or with inflammation.
Can it be treated?
Glaucoma is most commonly managed with medications only. Surgical treatment is an option only in those who do not respond to these medications and in congenital glaucoma
Procedures & Services:
We offer all the facilities required in the diagnosis and the management of glaucoma at our hospital.
Initial glaucoma workup involves the measurement of the intraocular pressure (IOP) with the help of a Goldmann’s Applanation tonometer, evaluation of the angle of the eye with a Goldmann goniolens , examination of the optic nerve head by slit lamp bio microscopy and the measurement of the central corneal thickness using a pachymeter. Ultrasound biomicroscopy helps us to further assess angle details and dimensions and actively intervene based on the findings. We offer all these facilities in our hospital.
Visual field monitoring is a very important part of glaucoma management. We have the Humphrey’s Field Analyzer strategy that allows us to monitor visual fields efficiently, assess progression if any and change our mode of approach.
Optical Coherence Tomography (OCT) is the latest in glaucoma diagnostics that gives us a quantitative measurement of the retinal nerve fibre layer, the part of the eye damaged in glaucoma. We offer this technology to you in the form of the Carl Zeiss Spectral Domain OCT.
Stereoscopic photographs of the disc for documentation of the changes in the optic disc can be taken on the the Zeiss VisuPac and FF450 plus fundus camera.
Although medications are the mainstay of glaucoma management, laser is required in certain types of glaucoma. We have the facility to do a laser iridotomy using the Zeiss YAG laser in cases of angle closure glaucoma. Another laser procedure in glaucoma, the laser trabeculoplasty is also done sometimes, for which we have the Diode laser.
Surgical procedures in glaucoma including trabeculectomy with and without antimetabolites, trabeculotomy and even glaucoma drainage valve implant placements are performed by qualified surgeons at our centre.
