The evidence presented shows that both methyl methacrylate and ethyl methacrylate monomers can diffuse through the rubber bulb of a dropper dispenser-style bottle. Methyl methacrylate is substantially more efficient in this regard than is ethyl methacrylate, which leads to the loss of these products into the environment immediately around the dropper bottle. If a dropper bottle of these agents is stored in a confined space such as a storage tub along with certain local anesthetic cartridges, the monomer vapor can enter the cartridge and contaminate its contents. A combination of methyl methacrylate in the presence of 2% lidocaine with 1:100,000 epinephrine appears to be the most reactive of the combinations tested. Local anesthetic cartridges should not be stored in a confined space with dropper bottles containing either methyl methacrylate or ethyl methacrylate monomers.

The type and frequency of bacterial contamination of 638 in-use multidose eye drop bottles are reported. By dripping, bacteria were recovered from 82 bottles (12.9%). Bacterial growth considered to be clinically and microbiologically significant were found in 12 cases (1.9%). The swabbings from 38 of 180 dropper tips (21.1%) yielded bacteria, while none of the pipette aspirates from 196 bottles were positive. The flora obtained by dripping and swabbing was very similar to the normal conjunctival and skin flora. It is suggested that microorganisms isolated by dripping often originate from contaminated dropper tips. The frequency of contaminated drops did not increase with increasing duration of use of the bottles. Repeated examinations and inoculation studies indicated that the solutions were self-sterilizing. This indicates that multidose eye drop bottles preserved and dispensed as in the present study may be used for more than the usual 4 weeks without increasing the risk of ocular infection.

A device designed to improve the ability with which the patient instills eyedrops is described. This consists of a flexible, angled, vacuum-metallized polyester mirror with adhesive at one end to which a squeeze-type dropper bottle may be attached and, if desired, permanently affixed.

For the past 20 years, the author has been treating recurrent chronic seborrheic dermatitis with a suspension of human cerumen in glycerine. The cerumen is obtained from healthy children and young adults in which there is an over-production which requires removal. If the cerumen contains debris it is not used. The collected cerumen is suspended in 50% glycerine and left for several weeks to sterilize. It is then strained through a fine filter having been heated so that its is workable. The material is dispensed to the patient in a small dropper bottle and the patient is instructed to place two drops in the external ear canal once a week. The chronicity of seborrheic dermatitis must be explained carefully to the patient and the necessity for avoiding water, cosmetics and other materials must be stressed. The patient must be made aware that the cause of the condition is unknown and that periodic inspection of the ear canal is necessary in addition to the topical application of the cerumen suspension.
