Miotic-induced retinal detachment (RD) is a condition that is not recognized as such by common consent. Clinically it has been shown that all miotic agents, whether strong or weak, can precipitate an RD, if there are additional contributing factors like high myopia, peripheral lattice degeneration of the retina, pathological vitreoretinal changes and previous history of an RD in the other eye, which all increase the basic risk of RD. Pilokarpin lameller 11 mg® represents a form of miotic therapy having initially only a moderate accommodative and miotic effect, which further declines to a level of steady state during the next hours. Because the time interval after which a new Pilokarpin lameller unit is required lasts up to 1 week, the total amount of accommodation and miosis is much smaller than when applying daily 2% pilocarpine drops. However, it seems important, before the start of any kind of miotic therapy, to perform a careful examination and management of virtually all detachment-prone patients. This case report deals with an RD which occurred after 2 days of treatment with Pilokarpin lameller (Ocusert®) 11 mg in a myopic patient who had a juvenile type of glaucoma and previous history of an RD in the other eye.
