Glaucoma is a chronic eye condition that cause gradual vision release due to irreversible hurt of optic nervus , which is because of increase intraocular pressure . The treatment of glaucoma ; be iteye drops , optical maser or incisional surgery design at lowering intraocular air pressure to prevent / slow optical nerve impairment .
mostly , the first line of discussion for glaucoma is medicament follow by optical maser and other operative routine if glaucoma is not controlled with conservative treatment . operation affect optical maser or incisional surgery and usually laser operation is recommended prior to incisional operating room . In laser , a focussed short beam is used to release intraocular pressure by treating trabecular meshwork . Various optical maser OR used to address glaucoma are selective optical maser trabeculoplasty ( SLT ) , argon laser trabeculoplasty ( ALT ) , optical maser peripheral iridotomy ( LPI ) and optical maser cyclophotocoagulation .
Laser trabeculoplasty is ordinarily performed in patients with undefended angle glaucoma when middle drops and medications fail to reduce the intraocular pressure . There are basically two types of laser trabeculoplasty that admit argon laser trabeculoplasty ( ALT ) and selective laser trabeculoplasty ( SLT ) .
Laser Cyclophotocoagulation : This optical maser treatment is unremarkably reserved for severe glaucoma affected role who have terrible vision release . It is used to put down ciliary bodies that produce aqueous humor , which will run to decreased intraocular pressure .
In incisional surgery ( filtering surgical procedure ) , an artificial drainage golf hole is make in sclera with procedure such as trabeculectomy or sclerostomy to free intraocular pressing . Aqueous bypass devices , which are used as artificial drainage machine are also becoming popular at reducing intraocular pressure . The exercise of shunts used are Ahmed shunts ( valved ) or Baerveldt shunts ( non - valved ) . There are also newer procedures known as minimally invasive glaucoma OR ( MIGS ) that control promise at treating glaucoma . These include Trabectome , iStent and CyPass Micro - Stent .
Trabeculectomy ask partial remotion of clogged trabeculate meshwork with the help of incisions to release the intraocular pressure ( IOP ) . Hence , a new drainage pathway for aqueous witticism is create and this liquid collect under the upper conjunctiva in a bleb figure capillary blood circulation , thus take down the intraocular pressure .
Trabeculectomy is performed when other treatment options such as medications , eye drop cloth or laser surgery are not effective at let down intraocular pressure . The OR aims at lessen intraocular pressing in assailable angle glaucoma by give trabecular meshwork . In closed angle glaucoma , the intraocular insistence is scale down by create small pickle in the fleur-de-lis .
How Long Does It Take To Recover From Glaucoma Surgery?
The retrieval of a glaucoma patient from laser is quick and the patient role can summarise his day-after-day activity like a shot the next day after laser handling , but MD advise to obviate center straining , labored lifting , bend for a few weeks as a precautionary touchstone for both optical maser and conventional operating theatre . Glaucoma symptom are relieved within a few days after laser surgery with minimal post - surgical symptom of modest irritation , redness and tearing .
The recovery time in incisional surgery is ordinarily longer extending from 2 to 4 weeks and it may even take up to 2 months for vision to stabilize . The rare side effects of glaucoma operating theater admit loss of vision , contagion , sensitiveness to light , farsighted term soreness of the eye , bleeding , small heart imperativeness , scarring , cataractand / or need for more surgery .
