Lipid chemistry

Meibum is a complex soup of variable lipids and lipid

derivatives. The melting point varies according to the exact

composition.

Properties of fatty acids and their derivative lipids depend on

chain length and being unsaturated

Unsaturated FAs have a lower melting point than saturated

FAs of same length

e.g.

C18 – Stearate ( zero double bonds) melts at 69.6ºC

C18 – Oleate ( one cis double bond) melts at 13.4ºC

Meibomian gland dysfunction and ocular

discomfort in video display terminal workers C Fenga1, P Aragona2, A Cacciola1, R Spinella2, C Di Nola1, F Ferreri2

and L Rania2 Eye (2008) 22, 91–95; doi:10.1038/sj.eye.6703025; published online 26 October 2007

• Results

• A total of 52 subjects out of 70 (74.3%) had MGD.

• A statistically significant correlation between the symptoms of ocular

discomfort and hours spent on VDT work was observed in the total

population (r=0.358; P=0.002; 95% CI 0.13–0.54) and in the group of

subjects with MGD (r=0.365; P=0.009; 95% CI 0.103–0.58). Such

correlation was not shown in subjects without MGD.

• Conclusions

• The high prevalence of MGD among the subjects with symptoms of ocular

discomfort suggests that this diagnosis should be considered when

occupational health practitioners encounter ocular complaints among VDT

operators. It appears that MGD can contribute to the development of

ocular discomfort in VDT operators.

Conclusions: Paramdeep Bilkhu et al

The MGDRx EyeBag does produce an increase in

external and internal eyelid temperature.

Based on the results, either surface of the MGDRx

EyeBag can be used but 5 minutes application

using the silk surface demonstrates greater

increases of eyelid temperature necessary for

optimal heating
