Retropalpebral

The mould reproduces the exact configuration of the retropalpebral space and by making it a little larger at the point where the conjunctival sac is obliterated the continuous, gentle pressure restores a groove or makes it deeper, so that the prothesis can be better borne.

The writer has concluded that the sterilization of conjunctival trachoma can be obtained by germicidal agents; that copper, in the form of the sulphate, is as specific in granular ophthalmia as mercury or arsenic in syphilis; that the application of sulphate or copper by injection under the retropalpebral conjunctiva is the method of choice, not excluding the classical treatment by applications and instillations.

A female Thelazia callipeda, about 1 cm. in length, was found in the retropalpebral conjunctival sac of the left upper eyelid in a 4 year old girl.

The palpebral pump exerts positive pressure on the fluid in the retropalpebral canal. This retropalpebral canal exists only during the short phase of complete eyelid closure.

To encompass the entirety of the tear film, composed of the interpalpebral and retropalpebral portions, the neologism ‘dacruon’ was termed (Cher 2007, 2008). The dacruon represents the mucoaqueous layer and lipid sealant of the interpalpebral portion of the tear film as well as the opposing mucoaqueous reservoirs of the palpebral and conjunctival surfaces in the retropalpebral portion, which lacks an outer lipid layer.
