Pearl Necklace Sign: An interesting vitreous fi nding of possible fungal endophthalmitis

Endophthalmitis is severe ocular infl ammation due to bacterial or fungal infection involving the intraocular cavities and other adjacent intraocular tissues. Endophthalmitis may be endogenous or exogenous. The exogenous type may occur following an intraocular surgery or penetratingocular injury. Although Bacillus and Aspergillus species are major etiologic agents of post-traumatic endophthalmitis, fungi can also causeexogenous endophthalmitis. The small vitreous abscesses like a chain or rosary achieve the appearance of ‘’the pearl necklace’’. Pearl necklacepattern is a characteristic but not a pathognomonic sign of posttraumatic endophthalmitis caused by fungus.
