Abstract Details


to examine the morphological changes in the meibomian gland of patients with keratoconus


Sohag Refractive center, Sohag, Egypt


Examination of the meibomian gland of 300 kertoconus patients presenting to the center using infrared non contact meibography system (Sirius, CSO, Italy) between January 2017 – January 2018. 100 eyes of healthy individuals were also enrolled as a control group. Mean age of keratoconus patients was 19±12.9 years and 20± 7.7 in control group. Tear break up time test and Schirmer test I were evaluated. Subjective symptoms were also noted.


Average TBUT was 8±4.2 sec. and average Schirmer test was 8.2±8mm which was significantly lower than control group (p=0.05) Meibomian gland loss in the lower eyelid of the keratonus group was: grade 0 (no loss of meibomian glands) 100 eyes, grade 1 (gland dropout area <1/3 of the total meibomian glands): 85 eyes, grade 2( gland dropout area 1/3 to 2/3): 68 eyes, grade 3 (gland dropout >2/3):47 eyes.


Keratoconus shows significant mebomian gland loss that can be recorded by meibography Sirius meibography is a simple, non contact, cost effective method of evaluating meibomian gland loss as a part of the routine examination.
