Corticosteroid (triamcinolone acetonide) injection of chalazion intralesionally is an effective, easy and a safe method. Perfect recovery was achieved in 88% of 24 chalazion cases (22 patients). Most of them were cured with a single injection. The steroid therapy is most effective when the chalazion has not been secondarily infected. If this has already happened surgery is the method of choice. If the steroid injections are limited only to common non-infected chalazia, the results will be excellent in about 100% of the cases. This treatment may be recommended especially for children and persons with allergy to local anaesthetics. It is particularly suitable for chalazia located close to the lacrimal punctum. Because of its simplicity, efficiency and almost nonexistent risks, this method should also be convenient to physicians other than ophthalmologists.
Many aircraft passengers wearing contact lenses have complained about visual disturbances, tearing and smarting of the eyes. This kind of discomfort has been named jet‐set disease. The literature on this subject has been reviewed. Also my own study is reported. In that study seven test persons were examined during four hours in a decompression chamber. The atmospheric pressure was lowered to 560 millibars, which corresponds to an altitude of 4,000 metres. All test persons wore soft contact lenses. Objective symptoms were verified in four eyes after one hour and in all 14 eyes after three hours. The most serious objective findings were corneal erosions in 4 and opacities of corneal stroma in 10 eyes. The two investigators who did not wear contact lenses remained without both subjective and objective symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
