External eye examination should include checking for local eye signs (conjunctival congestion, tearing, discoloration, etc.), concomitant proptosis with motor neuropathy (this would localize the lesion to orbit/orbital apex or cavernous sinus), and ptosis (third nerve palsy).

It is important to become proficient at eye examination. This relies on practice. There are essential components that can be completed by most doctors, and other more specialised tests that are usually performed by ophthalmologists or optometrists.
Monographs of Topical Drugs that Have Caused Contact Allergy/Allergic Contact Dermatitis
Published in Anton C. de Groot, Monographs in Contact Allergy, 2021
In Tokyo, Japan, in the period january 1987 to December 1995, 141 patients were patch tested with eye drops and 49 individuals (35%) reacted positively and were diagnosed with allergic contact dermatitis. In 36 cases ingredient patch testing was performed and there were three reactions to phenylephrine HCI (8). In two hospitals in Spain, before 1993, five patients suspected of contact allergy to PE were investigated. All had developed ocular complaints 12-24 hours after eye examination by an ophthalmologist. When patch tested, 4 reacted to PE 10% water. A fifth was negative, but had a positive intradermal test to PE (1 mg/ml) after 2 days, which was also the case in the other 4 patients. Twenty controls were negative to the intradermal tests (57). One of the patients allergic to PE had taken a tablet containing pseudoephedrine sulfate for rhinitis and within 8 hours experiences itchy and red eyes, generalized itching and a maculopapular eruption. This was considered to result from cross-reactivity to pseudo-ephedrine, although a patch and intradermal test to it were negative (57).

As people age, eye care organizations suggest the need to increase the frequency of eye examinations. The American Academy of Ophthalmologists recommends that adults with risk factors over 55 years of age undergo an eye examination every 1 to 2 years.20 We consider that an interval of 12 months better estimates the utilization of eye care services taking into account the increased prevalence of comorbidities with age, the recommendation that people over 65 years old undergo an annual eye examination, and the recall bias of the participants.21–23 As part of the section on eye health of the ENDES, participants are asked if they have ever had a visual acuity examination and the date of the last evaluation before the survey. Therefore, the dependent variable of the study was having undergone a visual acuity examination in the last 12 months (Yes/No).
Willingness to Pay for Spectacle: An Outreach-Based Cross-sectional Study
Published in Ophthalmic Epidemiology, 2021
The questionnaire validity ensured after independently reviewed by two experienced optometrists and agreement reached. In addition, a pre-test conducted on 15% of the sample size at Gondar Tertiary University Hospital outpatient department. Optometrists used a structured questionnaire to collect demographic and socioeconomic data, the history of spectacles uses, source of spectacles, and future preferences. Comparison placed between willingness to pay for spectacles and the least spectacle price (US$ 12.5) at public-owned University of Gondar opticals dispensing units. Subjects’ eye examination, vision test, and refractive assessment were performed by optometrists. Presenting distance vision at 6 meters and near vision at 40 centimeters were taken under an illuminated room condition by using the Snellen chart. Presenting distance visual acuity less than 6/18 in the better eye considered visually impaired. Presbyopia was defined as a person whose age was greater than 35 years and presenting near vision acuity worse than 6/15 (N8) at 40 centimeters or if the addition of at least +1.00DS was required to improve near vision to at least 6/15 (N8) on top of distance correction. Subsequently, pinhole tests and detailed refraction were performed. Spectacles were given for subjects who have a distance and/or near refractive error.

In a third of the affected eyes at presentation, patients were asymptomatic (61 eyes, 33.5%). Asymptomatic children were referred by the pediatric rheumatologist for a routine eye exam in case they had JIA. Some were referred by their local ophthalmologists following a routine eye exam or by the pediatric optometrist for suspected ocular pathology or referred from school because they failed the screening exam performed for the first-grade children. (The Israel pediatric ophthalmology society recommends on a routine eye examination at the ages of 6 months, 3, and 6 years). The majority of those asymptomatic children suffered from JIA-associated uveitis (45% of asymptomatic eyes), the second-most common cause was intermediate uveitis (26% of asymptomatic eyes), 13% had CAU with no diagnosis of JIA, 13% had panuveitis, and one infant was diagnosed with bilateral congenital retinal toxoplasmosis at the age of 1 month.
