Meibomian gland dysfunction (MGD) may well be the leading cause of dry eye disease throughout the world
MGD is a chronic, diffuse abnormality of the meibomian glands, commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in the glandular secretion. It may result in alteration of the tear film, symptoms of eye irritation, clinically apparent inflammation, and ocular surface disease. In a few seconds the device allows to take photo with high resolution in infrared vision making visible in every environmental condition the presence/absence of the glands on the eyelids.
Through an acquisition of images with infrared camera, the ICP MGD allows the evaluation of the glands.
The criticality is made through five-level scale. The evaluation scales are an essential instrument for the registration and for the clinical monitoring of the modifies to the ocular tissues.
These scales are used to evaluate the gravity of a wide range of conditions, included those associated to the contact lenses use.
On the other hand, the device is able to recognise and detect in a completely automatic way the loss area of meibomian glands. After taking the picture, the software only asks to indicate the area of the eyelid that you want to analyze, and then it detects all glands.
The dysfunction of the Meibomian Glands (MGD, Meibomian Gland Dysfunction) is caused by a chronic alteration of the sebaceous glands that are located inside of the eyelids.
The instrument has the possibility to be used in a portable way or like fixed instrument in your clinic, exploiting a support that you can insert inside the hole of the tonometer on the slit lamp.
Problematic evaluation of the dry eye
For dry eye diagnosis are recommended a series of exams:
Measurement of the blinking frequency and calculation of the inter blink interval
Measurement of the height of the lower tear meniscus
Measurement of the tear osmolarity (if available)
Calculation of the tear film break up time (TFBUT) and the index of ocular protection (OPI)
Classification of the corneal and conjunctival coloration with fluorescein
Phenol red test
Quantification of the morphological characteristics of eyelids
Squeezing: quantification of the squeezability and of the quality of the lipid component
Meibography: quantification of atrophy.
