Glaucoma is a inveterate heart condition that causes gradual vision deprivation due to irreversible wrong of optic nerve ; due to increased intraocular pressure . Glaucoma if not treated will continue to damage optic brass fibers , which transmit ikon to the brain , and will direct to personnel casualty of visual modality causing permanent blindness . The treatment of glaucoma aims at lour intraocular force per unit area to forestall / slow optic spunk damage .
Generally , the first note of treatment for glaucoma is medicament follow by laser and other surgical routine if glaucoma is not ascertain with materialistic intervention . surgical process involve a laser or incisional operating theater and usually optical maser OR is recommended prior to incisional surgery as optical maser is less encroaching . In laser , a focussed weak beam is used to release intraocular pressure by treat trabecular meshwork . Various optical maser surgeries used to address glaucoma are selective optical maser trabeculoplasty ( SLT ) , argon laser trabeculoplasty ( ALT ) , laser peripheral iridotomy ( LPI ) and laser cyclophotocoagulation . In incisional surgery ( filtering surgery ) , an artificial drainage jam is created in sclerotic coat with subroutine such as trabeculectomy or sclerostomy to release intraocular force per unit area . There are also newer procedures known as minimally trespassing glaucoma surgery ( MIGS ) that hold promise at treating glaucoma .
What Are The Side Effects Of Glaucoma Surgery?
Glaucoma surgical process has proven to successfully slow glaucoma progress by lowering the intraocular pressing . However , the damage that has already been done to ocular face can not be reversed with glaucoma surgeries . In addition , if glaucoma is not treated appropriately , it will surely shape up to vision loss . Although , there are rarefied side issue of glaucoma surgery , but the possible side effects that a patient might have admit loss of imaginativeness , infection , sensitiveness to wakeful , long term inflammation / provocation of the eye , bleeding , low eye pressure , pit , cataractand / or need for more surgery .
Loss of Vision : There is impermanent loss of visual sense after glaucoma surgery , but on rarefied social occasion permanent vision can be completely lost after glaucoma surgery .
Nevertheless , the permanent loss of vision is a very rare side burden and commonly patient role benefit from glaucoma surgery .
Infection : Antibioticsare given prophylactically before and after the surgery along with everlasting sustentation of sterilization during the operating theatre to prevent any infection . However , even after these forethought , some patient might develop infection that might lead to visual modality loss , therefore , star sign of infection such as pain in the ass , eye red and/or extravagant tearing should be describe to oculist and needed antibiotic treatment should be ask to avoid any serious damage to the eye .
bleed : This is a uncommon complication and use of blood thinners should be discussed with ophthalmologist prior to the surgical process if the patient is on anticoagulants .
Scarring : Glaucoma OR may go wrong in the foresightful streamlet due to pock or natural healing of the eye , which lead to increased intraocular pressure sensation . This might require re-start medication or postulate for repetition surgery .
Lower Eye Pressure : On occasions , glaucoma surgical operation leave to lower eye pressure acknowledge as hypotony . This is a temporary effect soon after surgery that might do peripheral visual change . The intended air pressure is achieved after some time , but on occasions hypotony persists that requires another surgery to correct it .
Cataract : It is precipitated with glaucoma operating theater , but cataract can be fixed well by operating room . It depends on the ophthalmologist whether to treat glaucoma and cataract at the same fourth dimension and depends on the impact it is causing on vision .
There are sure risk factors for build up complications after glaucoma surgical procedure , which includeobesity , diabetes , high blood pressing , smoking , shed blood disorders , infections , and heart and lung diseases .
After glaucoma OR if a patient role experiences sudden / severeeye pain , loss of vision or other visual alteration , signs of contagion ( fever / chills),nausea , vomiting , inflammation , swelling , abnormal centre emission , excessive bleeding , coughing , truncation of breathand / orchest pain , then the patient should immediately reach out to the doctor .
Although , a patient may sometimes know the above side effects , which are rare , but most of the prison term the surgery is successful in boil down intraocular pressure and slowing glaucoma forward motion , thus preventing permanent blindness .
