Dermatologists' Knowledge and Attitudes Toward Dry Eye Disease, Refractive Surgery, and Contact Lenses When Prescribing Isotretinoin in Saudi Arabia

Isotretinoin-Related Eye Dryness in Acne Patients in Qassim, Saudi Arabia

Background Isotretinoin is a commonly prescribed agent mainly used to treat acne vulgaris. Since its Food and Drug Administration (FDA) approval, the subject of its associations with various medical conditions has become a growing interest in many investigational studies. Methodology A retrospective study was conducted using the validated Standardized Patient Evaluation of Eye Dryness (SPEED) questionnaire. All statistical calculations were performed using the Statistical Package for the Social Sciences (SPSS) version 27.0.1 (IBM SPSS Statistics, Armonk, NY). Results The research study involved 107 participants, predominantly Saudi nationals (98.1%), with an average age of 22 years. Regarding the total cumulative dose (TCD), 40.2% had less than 50 mg/kg, 33.6% had between 50 and 100 mg/kg, and 15.9% had more than 100 mg/kg. The majority (73.8%) did not stop using isotretinoin. The average Ocular Surface Disease Index (OSDI) score, indicating ocular surface disease symptoms, was 26.78. There was no significant association between gender, dose/duration of isotretinoin, TCD, and age, and OSDI scores. However, participants with severe OSDI scores were more likely to have worsened pre-existing eye symptoms compared to those with non-severe OSDI scores (35.1% versus 11.4%, p = 0.011). Conclusions This study contributes to the understanding of the impact of isotretinoin usage on ocular surface health. While no significant associations were found between gender, dose, duration, TCD, and age, and OSDI scores, participants with pre-existing eye symptoms were more likely to experience worsened symptoms during isotretinoin treatment.

Cross-Sectional Assessment of Dermatologists' Knowledge and Attitude Towards Isotretinoin-Related Ocular Side Effects in Aseer, Saudi Arabia

BACKGROUND

Acne vulgaris is a chronic inflammatory disease of the pilosebaceous unit, which includes the hair follicle, hair shaft and sebaceous gland. The only treatment that has an effect on all the main aetiological causes of acne is isotretinoin. However, it may have a variety of negative side effects. The aim of this study was to evaluate the knowledge and attitudes of dermatologists regarding ocular effects following isotretinoin prescribing in the Aseer region, Saudi Arabia.

METHODOLOGY

An anonymous online cross-sectional survey was conducted in August 2022 to investigate dermatologists' knowledge and attitude regarding isotretinoin-related ocular side effects in Aseer, Saudi Arabia. Participants were recruited using convenience and snowball sampling methods.

RESULTS

A total of 48 dermatologists were included in this survey. The age distribution ranged from 25 to over 60 years. Sixteen (37.5%) were aged 31-40 years, 29 (60.4%) were male and 20 (41.7%) were specialists. All dermatologists reported that it can cause dry eye, 32 (66.7%) reported that it can cause contact lens intolerance, 10 (20.8%) reported that it can cause a decrease in dark adaptation and two (4.2%) thought that it can cause ectopia lentis and retinoblastoma. Regarding attitude, 43 (87.5%) thought that a course of isotretinoin is not recommended if the patient has recently undergone refractive surgery, 30 (62.5%) always inform patients about ocular side effects, 31 (72.9%) do not consider referring patients for ophthalmic examinations before initiating isotretinoin, 12 (25.0%) always prescribe lubricant eye drops, 15 (31.3%) always ask patients about recent refractive surgery, 17 (35.4%) always warn patients about avoiding refractive surgery during isotretinoin use and 19 (39.6%) always inform patients concerning discomfort with contact lenses.

CONCLUSIONS

The survey reveals that dermatologists in Aseer, Saudi Arabia, generally have good knowledge of isotretinoin related to some ocular side effects, especially dry eye and contact lens intolerance. However, there is some variation in their practices with regard to patient education, referrals for ophthalmic examinations, the use of lubricant eye drops and refractive surgery during isotretinoin treatment. Thus, dermatologists should receive educational training on the safety profile of isotretinoin while managing acne vulgaris.

Patients’ Awareness of the Ocular Side Effects of Isotretinoin Therapy: A Study From Saudi Arabia

Introduction

Isotretinoin is one of the most commonly prescribed drugs among dermatologists because it's used in the treatment of Acne vulgaris. Despite having an adequate safety profile, isotretinoin-related adverse events are common, with ocular manifestations being one of them. Although being generally mild, ophthalmologic manifestations associated with isotretinoin may cause significant ocular morbidity.

Objectives

The objective is to evaluate the awareness of the ocular side effects of isotretinoin treatment in patients with acne and to understand the treating physicians' practice of prescribing isotretinoin from the patient's point of view.

Method

A descriptive cross-sectional study was conducted on a Saudi Arabian population from June to September 2021. We used a self-administered questionnaire to collect data on drug dose, treatment duration, ocular adverse effects, patients' awareness, and patients' perception of treating physicians' practice.

Results

Of 1,157 responders, 452 (39.1%) consisted of participants who met the inclusion criteria, therefore they were enrolled in the study. Out of our responders, 308 (68.1%) were women. Approximately, 91.6% of participants had a dermatologist's prescription for isotretinoin. Eye dryness was the most commonly reported ocular adverse effect (83.4%). Blepharitis and conjunctivitis were the most commonly diagnosed complications after starting isotretinoin (5.4% for each).

Approximately, 71.2% participants were not advised to see an ophthalmologist for ophthalmological screening. Physicians asked only 78 (17.3%) respondents about a recent refractive surgery before starting isotretinoin or if they intended to undergo a refractive surgery in the next six months. Approximately, 57.5% participants were unaware of possible contact lens intolerance. Lubricant eye drops were prescribed to 305 (67.5%) respondents during isotretinoin treatment. Approximately, 36.7% participants were advised to consult their treating physicians if they had any serious ocular signs or symptoms.

Approximately, 67.9% participants reported their awareness of the ocular side effects of isotretinoin therapy. However, 236 (52.2%) participants responded that they were not provided with sufficient information on the ocular side effects of isotretinoin therapy.

Dermatologists' Knowledge and Attitude Toward Isotretinoin Ocular Side Effects in Egypt

Aim

The FDA approved isotretinoin for moderate and severe nodulo-cystic acne, in which it proved effective. However, this misled the dermatologists into using isotretinoin for mild cases as well. This misuse increased the risk of developing adverse effects, especially on the ocular system. These adverse effects vary from mild reversible eye dryness to severe irreversible loss of night vision. Also, it causes contact lens intolerance and corneal ulcer on top. Both ophthalmologists and dermatologists have different perceptions of the drug.

Purpose

To evaluate dermatologists' knowledge and attitude toward ocular adverse effects of isotretinoin in Egypt.

Methods

This cross-sectional study was conducted via an online questionnaire. The questionnaire had three parts: 1) demographic data, 2) knowledge about isotretinoin dry eye disorders, contact lens intolerance, and refractive surgery precautions and 3) dermatologists' management of a case on isotretinoin therapy. We contacted 111 participants from Facebook dermatologists' groups between March and April 2021.

Results

We surveyed 111 dermatologists. One hundred and five (94.6%) reported their knowledge about ocular side effects. One hundred of them (90.1%) informed their patients about the drug's adverse effects. Eighty-three (74.8%) reported their knowledge about contact lens intolerance. Forty-one dermatologists (36.9%) screened their patients for recent refractive surgery before isotretinoin therapy. Nearly, all dermatologists routinely prescribed lubricant eye drops for the patients, and 63 (56.8%) dermatologists sometimes referred their patients to an ophthalmologist. We found an association between knowledge about contact lens intolerance and years of experience (p=0.012). As well, we found that the academic degree of dermatologists is directly proportional with warning patients about ocular side effects (p=0.003) and refractive surgery (p=0.039).

Conclusion

Egyptian dermatologists were knowledgeable about the effects of isotretinoin on eyes with inappropriate clinical practice.
