Can some of the iridotomy risks be predicted based on the eye tests pre surgery? read about retinal detachment after the procedure in some cases.

Very rare: Have not seen a retinal detachment after routine laser iridotomy. Was reported in the literature as a case report after super high energy used. Maybe could have had an unknown tear that led to the detachment.

Probably not: Iridotomy is done to prevent attacks of acute glaucoma and is very effective. Retinal detachment following this procedure is extremely rare and should not be a concern given the seriousness of acute glaucoma. If you need an iridotomy, go for it.

Not really: Categorically speaking eyes with high myopia have greater risk of retinal detachment. However there is nothing per see that would predict risk for iridoty specifically, esp. As it pertains to risk of retinal detachment following the procedure.
