To investigate the applicability of in vivo laser scanning confocal microscopy in the diagnosis and follow-up of ocular demodicosis infestation in a prospective controlled study.
Fifteen right eyes of 15 patients with blepharitis associated with cylindrical dandruff (10 males, 5 females; mean age: 62.9 ± 9 years) and eight right eyes of eight age- and sex-matched control subjects underwent HRTII/RCM, evaluation of ocular symptom scores, tear function tests including vital stainings, Schirmer test, and tear clearance test, and evaluation of mite numbers in the eyelids.
In vivo confocal microscopy effectively disclosed the mites in the terminal bulbs of the eyelashes, which were not observed after treatment. Eyelids with demodicosis infestation showed marked inflammatory infiltrates around the meibomian glands and conjunctiva, which cleared with tea tree oil treatment.
Laser scanning confocal microscopy seems to be an efficient noninvasive tool in the diagnosis and follow-up of ocular demodicosis infestation.
