Ex amplissimi gratiosissimique Collegii Medici Inclytae Academiae Basiliensis decreto ac permissu, Theses sequentes de praecipuis adnatae oculi tunicae affectibus

XXIII.
Pterygium, as also hyposphagma, are of easy cure from the beginning, whereas they can almost never be cured with the passage of time.

XXIV.
Lippitudes occur mostly in the time of summer. It is good for a blear-eyed person to be seized by a flux of the bowels. In southern regions and in warm and humid temperatures, ophthalmia happens frequently and is easily cured; in the opposite climates, the contrary is true.

XXV.
The enumeration of signs is followed by the Treatment, which consists of diet, pharmacy, and surgery.

XXVI.
The regimen of life in Pterygium, therefore, should be established in such a way that it attenuates thick and viscous humors.

XXVII.
Hence, let the whole body be purged of these same thick and viscous humors, after first administering medicines that have acquired the power of attenuating and concocting.

XXVIII.
Afterward, fomentations are appropriate, as well as those things that are able to cleanse and repurge.

XXIX.
If nothing is achieved by these, one must finally resort to Surgery; for an old and indurated Pterygium can only be cured by incision.

XXX.
Regarding Suggillation, in the beginning, discutients substances that disperse humors combined with astringents are appropriate; afterwards, only digestives should be used.

XXXI.
A rupture or contusion indicates consolidation, whereas plethora indicates detraction; the former is completed by astringents, the latter either by phlebotomy, if other factors concur, or by a sparse diet, or by cupping glasses affixed to the neck, or finally by purging, if cacochymia ill condition of the humors is present.
