No clear benefits in preventing loss of visual field were found for eyes treated with peripheral laser iridotomy. There was weak evidence suggesting that laser iridotomy could

There is no cure, but pigmentary glaucoma can be managed with eye drops or treated with simple surgeries. If caught early and monitored, chances of glaucoma are greatly reduced.
