Purpose
To report a case about a post-traumatic unilateral dispersion syndrome in a young male that is anatomically predisposed.
Setting
We report the case of a 18 year old male with no significant ophthalmic and non-ophthalmic history who is practicing judo at a professional level and been victim of a blunt trauma to his right eye while practicing.
Methods
His exam on the day of trauma showed a visual acuity to the right eye of 6/10 compared to 10/10 OS,and a subjective refraction of -1.75(-0.5 à 20°) and -1.25 ,no relative afferent pupillary deficit,ocular motility was normal with mild conjunctival hyperhemia and corneal edema the anterior chamber contained 3+ pigmented flare with with pimented deposits on the anterior capsule of the lens.Gonioscopy showed a highly pigmented trabeculum with no angle recession.IOP was 12 mmHg OD and OS.
Ocular fundoscopy showed a symetric papilla with an excavation of 4/10 and conserved foveal reflex.
Results
The diagnosis of pigment dispersion syndrome was made on multiple arguments:young male,myopia,presence of pigmented flare deposited on anterior capsule of the lens.
Ultrabiomicroscopy showed a concave iris with irido-zonular contact.
Treatment based on local corticotherapy and corneal anti-edematous was started with notable amelioration of visual acuity to 10/10 and disappearance of pigmented flare but persistance of the depositis on the anterior capsule of the lens and the endothelium.
Conclusions
Pigment dispersion syndrome (PDS) and its potential sequel, pigmentary glaucoma, are characterized by the anomalous dispersion of pigment granules within the ocular structures.
The primary cause of PDS and PG is the release of pigment into the anterior chamber due to the iris rubbing on the zonules and lens.
Risk factors include male sex, age 20-40 years, myopia, and Caucasian ethnicity.
Presentation is usually bilateral but in the case of our patient,the ocular trauma caused a unilateral pigment dispersion syndrome in a predisposed eye.
