- Details on study design:
- SELECTION AND PREPARATION OF ISOLATED EYES
The eyelids on the heads were carefully cut away with scissors, avoiding damaging the cornea. One small drop of 2% (w/v) fluorescein solution was applied onto the cornea surface for a few seconds and subsequently rinsed off with 20 mL physiological saline. Then the fluorescein-treated cornea was examined with a hand-held slit lamp or slit lamp microscope, with the eye in the head, to ensure that the cornea was not damaged. If the cornea was in good condition, the eyeball was carefully removed from the orbit.
The eye ball was carefully removed from the orbit by holding the nictitating membrane with a surgical forceps, while cutting the eye muscles with bent scissors. Care was taken to remove the eyeball from the orbit without cutting off the optical nerve too short. The procedure avoided pressure on the eye while removing the eyeball from the orbit, in order to prevent distortion of the cornea and subsequent corneal opacity. Once removed from the orbit, the eye was placed onto damp paper and the nictitating membrane was cut away with other connective tissue. The prepared eyes were kept on the wet papers in a closed box so that the appropriate humidity was maintained.
EQUILIBRATION AND BASELINE RECORDINGS
The prepared eye was placed in a steel clamp with the cornea positioned vertically with the eye in the correct relative position (same position as in the chicken head). Again avoiding too much pressure on the eye by the clamp. Because of the relatively firm sclera of the chicken eyeball, only slight pressure was needed to fix the eye properly. The clamp with the eyeball was transferred to a chamber of the superfusion apparatus. The clamp holding the eye was positioned in such a way that the entire cornea was supplied with physiological saline solution dripping from a stainless steel tube, at a rate of approximately 3-4 drops/minute or 0.1 to 0.15 mL/minutes. The door of the chamber was closed except for manipulations and examinations, to maintain temperature and humidity.
The appropriate number of eyes was selected and after being placed in the superfusion apparatus. There they were examined again with the Haag-Streit BP 900® slit lamp microscope to ensure that they were in good condition. The focus was adjusted to see clearly the physiological saline which was flowing on the cornea surface. Eyes with a high baseline fluorescein staining (i.e., > 0.5) or corneal opacity score (i.e., > 0.5) were rejected. The cornea thickness was measured, any eye with cornea thickness deviating more than 10 % from the mean value for all eyes, or eyes that showed any other signs of damage, were rejected and replaced. If the selected eyes were appropriate for the test, acclimatization started and it was conducted for approximately 45 to 60 minutes. The chambers of the superfusion apparatus were at controlled temperature (32±1.5°C) during the acclimatization and treatment periods.
At the end of the acclimatization period, a zero reference measurement was recorded for cornea thickness and opacity to serve as a baseline (t=0) for each individual eye. The cornea thickness of the eyes should not change by more than 5% within the -45 min and the zero time. No changes in thickness (0.0%) were observed in the eyes. Following the equilibration period, the fluorescein retention was measured. Baseline values were required to evaluate any potential test item related effect after treatment. All eyes were considered to be suitable for the assay.
NUMBER OF REPLICATES
One eye was treated with the negative control. Three eyes were treated with the test item and another three eyes with the positive control.
NEGATIVE CONTROL USED
Physiological saline (Salsol solution, 0.9% w/v NaCl)
POSITIVE CONTROL USED
Benzalkonium chloride solution, 50 % in water diluted to obtain a 5% (w/v) solution
APPLICATION DOSE AND EXPOSURE TIME
30 µL was applied to the entire surface of the cornea attempting to cover the cornea surface uniformly for 10 seconds
OBSERVATION PERIOD
Prior to treatment and at approximately 30, 75, 120, 180 and 240 minutes after the post-treatment rinse (fluorescein retention is determined only prior to treatment and 30 minutes after test chemical exposure)
REMOVAL OF TEST SUBSTANCE
- Volume and washing procedure after exposure period: The cornea surface was rinsed thoroughly with 20 mL physiological saline at ambient temperature, taking care not to damage the cornea but attempting to remove all residual of the test item if possible.
- Indicate any deviation from test procedure in the Guideline: No deviation
EVALUATION
Corneal thickness or swelling determination: Corneal swelling is determined from corneal thickness measurements made with an optical pachymeter on a slit-lamp microscope with the following settings: Slit length/full length/position 8 and Slit width/Fully open/Setting 9.5
Corneal opacity determination: Corneal opacity is scored using the area of the cornea that is most densely opacified with the following settings for the slit lamp microscope: Slit length/full length/position 8 and Slit width/Fully open/Position on indefinite
Fluorescein retention determination: The fluorescein retention will be measured on two occasions, baseline (t=0) and 30 minutes after the post-treatment rinse. the setting for the slip lamp microscope is identical to the opacity assessment, except with the green light filter

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditons of this study, Fir Needle Oil Canadian, was found to have an overall ICE Classification of 3xI. Therefore, based on this in vitro eye irritation in the isolated chicken eyes test with Fir Needle Oil Canadian (Fir, Abies Balsamea, ext), the test item is non-irritant, UN GHS Classification: No Category.
- Executive summary:
An in vitro eye irritation study of the test item was performed in isolated chicken’s eyes. The irritation effects of the test item were evaluated according to the OECD No. 438 (26 July 2013).
After the zero reference measurements, the eye was held in horizontal position and 30 µL of test item was applied onto the centre of the cornea such that the entire surface of the cornea was covered. After 10 seconds, the surface was rinsed with physiological saline. The positive control eyes were treated with 30 µL of 5% (w/v) Benzalkonium chloride solution. The negative control eye was treated with 30 µL of physiological saline (0.9% (w/v) NaCl solution). In the study, three test item treated eyes, three positive control treated eyes and one negative control treated eye were examined.
The results from all eyes used in the study met the quality control standards. The negative control and positive control results were in good correlation with the historical control data. Thus, the experiment was considered to be valid.
No corneal swelling was observed during the four-hour observation period on test item treated eyes. No significant corneal opacity change (severity 0.5) was noted on the three eyes. No significant fluorescein retention change (severity 0.5) was noted on one eye and no fluorescein retention change was noted on two eyes. No other corneal effect was observed.
Based on this in vitro eye irritation in the isolated chicken eyes test, Fir Needle Oil Canadian is non-irritant, UN GHS Classification: No Category.
