alexandrite laser ( 755 nm ) is one of the most common methods of hair removal .
however , the disuse of protective goggles during the application of this laser is a serious problem .
alexandrite laser light is visible , and it is known that ocular injuries may occur during the use of alexandrite laser when protective goggles are not worn [ 1 , 2 ] .
still , foveal injuries by alexandrite laser are rare . herein , we reported a case with accidental foveal injury and subsequent macular edema secondary to alexandrite laser contact , treated with an intravitreal ozurdex implant .
a 35-year - old male patient presented to our clinic complaining of a scotoma in the right eye , which had begun 2 h after looking at a laser probe for a few seconds in an esthetics clinic .
fundus examination showed a pale , white and sharply circumscribed laser spot lesion localized at the inferior nasal foveal region , involving the central foveola . a visual field test ( humphrey , zeiss , germany ) displayed a scotoma consistent with the affected region .
a hypofluorescent lesion , which was in accordance with the round laser spot , was detected in the early and late phases of fundus fluorescein angiography ( canon inc . ,
an intense increase in reflectance in the region of the spot was also identified on optic coherence tomography ( oct ; slo , optos , dunfermline , uk ) .
there was no change in the findings at the first control visit after 1 week .
however , at the second week , the bcva of the patient had decreased to 3/10 , and edema and hemorrhage had occurred around the lesion .
oct demonstrated intra- and subretinal edema as well as tissue disruption within the injured area ( fig .
ozurdex was implanted via the pars plana region with its specific cartridge in the operating room .
an intraocular pressure elevation ( 35 mm hg ) which was successfully controlled by a topical antiglaucomatous agent occurred .
one month after the injection , bcva was 20/30 despite a hemorrhage around the injured area on fundus examination ( fig .
oct showed decreased macular edema and a hyperreflectance scar in the affected area ( fig .
4 ) . a visual field test demonstrated no change in the scotoma of the patient .
it is known that alexandrite laser causes a temperature increase and subsequent coagulation necrosis in melanin - containing tissues , which is termed  selective photothermolysis .
this temperature rise might cause burns , pigmentation changes , and erythema in surrounding tissues .
the first type are anterior segment complications such as uveitis , pupillary distortion , iris atrophy , and cataract , which can occur due to laser applications to the face with closed eyes .
the second type are posterior segment complications such as macular hole   and macular scar   caused by the direct effect of the laser beam on the retina while the eyes are open .
the ozurdex intravitreal implant is composed of a biodegradable copolymer of lactic and glycolic acids containing micronized dexamethasone .
the drug - copolymer complex gradually releases dexamethasone that transforms into glycolic and lactic acids after the injection and eventually into water and carbon dioxide .
after intravitreal injection , the ozurdex implant reduces the vitreous levels of several mediators which cause disruption of the blood - retinal barrier ( i.e. , vascular endothelial growth factor ) and accordingly diminishes the vascular permeability .
ozurdex is frequently used in the treatment of macular edema due to diabetes mellitus , retinal vein occlusion , and noninfectious uveitis . in our case , we first used topical steroid drops to prevent complications after alexandrite laser injury ; however , this medication was ineffective .
therefore , the inflammatory process secondary to the foveal injury and the subsequent macular edema were treated with ozurdex because of its rapid and potent antiedematous effect . in a case report by anaya - alaminos
bcva was reported as 20/200 initially and 20/100 after a 1-year follow - up period in a patient with accidental foveal injury by alexandrite laser .
there was no information about the treatment or whether macular edema had occurred during the follow - up period .
we believe that the better final visual acuity in our case was achieved by swift resolution of macular edema by ozurdex .
retrobulbar and oral steroid treatments have been used in the treatment of foveal injuries caused by femtosecond laser and green laser pointer [ 9 , 10 ] .
bcva improved from 20/30 to 20/20 after treatment in a case with femtosecond laser injury , while it increased from 20/100 to 20/60 in a case with green laser pointer injury .
the difference between the initial visual acuities and their increases might have been caused by the different energy levels , the durations of laser contact , and the distances of the lesions from the central foveola .
the response to treatment was often greater among eyes with a shorter duration of macular edema .
we preferred an ozurdex implant to systemic steroids due to its rapid and target - oriented effect and the lower systemic side effects for reducing macular edema .
in summary , alexandrite laser injuries might cause macular injury and edema , and the ozurdex implant can be an effective treatment in these cases .
the patient was informed about the risks of the treatment , and informed consent was obtained .
 alexandrite laser is one of the most common methods of hair removal . 
 its utilization is gradually increasing due to easy accessibility and high effectiveness . 
 however , the disuse of protective goggles during the application of this laser is a serious problem . in this case report 
 , we presented a 35-year - old male patient who had foveal injury by alexandrite laser . 
 the inflammatory process secondary to the foveal injury and subsequent macular edema were treated with ozurdex because of its potent antiedematous effect .
