Conjunctivitis/Pinkeye
Published in Charles Theisler, Adjuvant Medical Care, 2023
Conjunctivitis from a viral infection usually clears up in about two weeks with or without treatment. Mild bacterial conjunctivitis may get better without antibiotic treatment and without causing any complications. It often improves in 2–5 days without treatment but can take two weeks to go away completely.1 Antibiotics may help accelerate healing from bacterial conjunctivitis, especially if there is a discharge of pus from the eye. An eye doctor needs to be consulted if the eye is red, there is moderate to severe pain, or there is sensitivity to light or blurred vision.2
Ophthalmic Emergencies

Viral conjunctivitis, due to the adenovirus (‘pink eye’) or enterovirus, is highly contagious. Person-to-person spread is rapid unless scrupulous care is taken with hand hygiene and towel or face washer use. Give antibiotic drops and ointment to prevent secondary bacterial infection.Refer the patient to the next ophthalmology clinic for a definitive diagnosis and to monitor for the development of keratitis.

Inflammation of several parts of the eye can impair vision. Redness, itching, and tearing of the eyes can be caused by bacteria, viruses, foreign particles, or environmental pollutants. Conjunctivitis is an inflammation of the conjunctiva which causes reddened eye (sometimes called "pink eye") and purulent or serous discharge with itching, smarting, stinging, or a scratching sensation. Allergic conjunctivitis is an inflammation resulting from allergens (such as ragweed, grass, or tree pollen) that irritate the conjunctiva and cause mast cells to release chemicals that interact with the allergen.
Curve fitting and jump detection on nonparametric regression with missing data

We use hierarchical cluster analysis to detect jump points with d = 13.8, 5 shows that there are three jump groups and so three jump points exist in the fitted curve, respectively in the end of January, the middle of April and the end of May as in Figure 6. Actually, January 29 is the Spring Festival Day and this dropping jump maybe well understood since most people stayed at home together with their family. To explain the other two jumps, we incorporate air quality such as PM2.5 and PM10 into this study. Generally, there would be a delay of 5–10 days for the impact of air quality on conjunctivitis. Figure 7 is a trend chart of air quality indicators such as PM2.5, PM10. We can see that air quality indicators are very high in early April while they significantly went down in mid-May. Therefore we believe that the occurrence of jump in the conjunctivitis clinic was resulted in by air pollution.

On the second day of his admission, the patient developed bilateral eye redness. This progressed over a duration of 3 days and a referral was made to the Ophthalmology department. Other than symptoms of progressive eye redness (left worse than right), he was otherwise asymptomatic. His vision was 20/20 in both eyes with normal intraocular pressure and unremarkable anterior and posterior segment examination. Portable slit lamp examination at bedside revealed bilateral follicular conjunctivitis with mild chemosis over the left eye. There were no pseudo-membranes and no tender or enlarged pre-auricular or cervical lymph nodes. Conjunctival swabs performed for this patient on the same day revealed an RT-PCR CT of 24.07 at the hospital laboratory. The patient was treated conservatively with preservative-free lubricants. The patient recovered well as shown in the photos in Figure 1. Two days after the initial swab, a second conjunctival swab was taken from both the eyes and was sent to the research laboratory for viral isolation and RT-PCR. The samples were negative for SARS-CoV-2 by RT-PCR and virus isolation was unsuccessful after three blind passages. The conjunctivitis resolved in 6 days.
Ocular Involvement in Muckle-Wells Syndrome

Two members of this family refused to have an extensive ophthalmic examination. Therefore, ocular findings in both eyes of nine individuals of the family were presented in this cross-sectional study. Each participant completed various questionnaires about their past and present symptoms and past ocular history. The onset age of the ocular symptoms were also inquired. A comprehensive ophthalmological examination, corneal topography and optical coherence tomography (OCT) evaluations were performed. Questionnaire of the symptoms covered the history of conjunctivitis including the irritated pink eye, conjunctival swelling, foreign body sensation, increased tear secretion and discharge of pus or mucus. We also questioned the recovery of symptoms after the commencement of therapy. Ophthalmological examination was performed by the same ophthalmologist (OY) and included ocular motility tests, best corrected visual acuity (BCVA) assessment, intraocular pressure measurement, slit-lamp biomicroscopy and fundoscopy. Signs of keratoconus, band keratopathy, subepithelial and/or anterior stromal corneal scarring, posterior stromal corneal opacification, corneal edema, cells and flare within the anterior or posterior chamber and vitreous, anterior or posterior synechia of the iris, phakic status of the lens, signs of past uveitis including pigment dispersion, and hyalinized keratic precipitates were examined in the slit-lamp biomicroscopy. The lesions on the retina and optic nerve were inspected during the dilated funduscopic examination.
