Abstract Details

Purpose:

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

Setting:

Sohag Refractive center, Sohag, Egypt

Methods:

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.

Results:

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.

Conclusions:

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.
