Abstract Details

Purpose:

To investigate the prevalence of Meibomian gland dysfunction (MGD) in a Chinese cataract population using ocular surface interferometry and dynamic meibomian imaging.

Setting:

Private Practice, Hong Kong

Methods:

Patients undergoing cataract surgery with monofocal intraocular lens implantation were recruited for imaging with ocular surface interferometry and dynamic meibomian imaging using LipiView II before surgery. The lipid layer thickness (LLT), partial blink (PB) rate, lower lid Meibomian gland dropout score and Meibomian gland dilation score were analysed.

Results:

Thirty-one patients were recruited during a 2-months period from September to November 2019. The average age was 69.7 ± 8.5. The gender ratio was 12 male :19 female. The mean lipid layer thickness (LLT) was 58.2 ± 18.9 nm. 7 out of 31 (22.6%) patients had one eye LLT value below 60 nm, indicating a high chance of MGD, whereas 15 patients (48.4%) had both eyes LLT below 60 nm, indicating a very high chance of MGD. The partial blink rate was 23.7%, where 6 patients (19.4%) had PB rate over 40%. For lower lid infrared meibography, the average Meibomian gland dropout score was 1.1 ± 0.7, and the Meibomian gland dilatation score was 1.8 ± 1.0.

Conclusions:

There was a high prevalence of MGD based on ocular surface interferometry evaluation at the time of cataract surgery in Chinese patients.
