Can Vitamin D Help with Dry Eyes?

Submitted by: Edmond Sandouk

Overview

Dry eye disease (DED) is a multifactorial disorder of theocular surface, in which inflammation is a central component of both symptoms and pathogenesis[1].

While vitamin D is recognized for its role in calcium regulation and bone health, it also has immunomodulatory and anti-inflammatory properties that may benefit ocular health[2].

Multiple studies have investigated the impact of systemic vitamin D supplementation on DED. Notably, Bae et al. conducted a randomized controlled trial on patients with DED and vitamin D deficiency. They demonstrated significant improvements in tear break-up time (TBUT), Schirmer’s test and ocular surface disease index (OSDI) scores following vitamin D supplementation[3, 4].

Building on this promising evidence, a recent clinical trial led by Hassanpour et al explored a novel approach: topical vitamin D eye drops[5].

Study Title

Safety and Efficacy of Topical Vitamin D in the Management of Dry Eye Disease Associated With Meibomian Gland Dysfunction: A Placebo-Controlled Double-Blind Randomized Controlled Trial[5].

Q&A: Insights from the Study

Q: What was the rationale for testing topical vitamin D?
A: Given the positive ocular benefits of systemic vitamin D, this study aimed to assess whether topical administration could provide local therapeutic effects in patients with DED associated with meibomian gland dysfunction (MGD).

Q: What was the study design?
A: The study was a double-blind randomized control trial including 56 patients with both DED and MGD. They were randomly assigned to receive either vitamin D eye drops or placebo eye drops, administered in one eye four times daily for 8 weeks.

Q: What were the results?
A: At 8 weeks, the vitamin D group demonstrated statistically significant improvements across all major outcomes compared to the placebo group:

Q: Were there any adverse effects?
A: The treatment was well tolerated. There were no statistically significant ocular adverse events compared to the placebo group, and no participants discontinued the study due to side effects.

Q: Are topical vitamin D eye drops commercially available?
A: The eye drops were specifically prepared for research purposes and are not currently available on the market.

Conclusion

Topical vitamin D appears to be a safe and promising option for the treatment of DED associated with MGD. This study highlights the need for further research and development of vitamin D-based ocular therapies.

Eyelid lesions are common in primary care

Most eyelid lesions are benign, but 5-10% of skin cancers are periocular, with 90% being basal cell carcinoma (BCC) and 5% squamous cell carcinoma (SCC) [1]. Risk factors include age, UV exposure, family history, immunosuppression, and fair skin [1]. Sebaceous carcinoma, malignant melanoma and Merkel cell carcinoma are important but less common eyelid malignancies.

Recognition and clinical evaluation of malignant eyelid lesions is crucial

BCC and SCC often affect the lower eyelid or medial canthus due to sun exposure. Evert the eyelids to evaluate the palpebral conjunctiva and fornix and assess for tissue fixation [1]. Features of malignancy include skin ulceration, telangiectasia, loss of eyelashes, distortion of eyelid architecture, and crusting [1,2]. Assess ocular motility, palpate regional lymph nodes, and scan sun-exposed areas on the face and body for other lesions. Unilateral blepharitis, or recurrent chalazia may masquerade as sebaceous carcinoma. The “ABCDE” criteria (Asymmetry, Border irregularity, Colour variation, Diameter >6mm, Evolution) aids in the evaluation of eyelid malignant melanoma.

Refer lesions with malignant features

Malignant lesions can resemble benign ones, making diagnosis challenging [1]. Refer suspicious cases to an oculoplastic surgeon or dermatologist for biopsy [1,2]. Treatment typically involves surgical excision with clear margins via Mohs or frozen section. For inoperable BCC, vismodegib is an option for extensive disease, while imiquimod may treat superficial cases.

Styes and chalazia are frequent in primary care

Generally, a stye is a painful, red, and pimple-like lesion caused by infection [3], whereas a chalazion is a non-infectious, painless bump on the eyelid [2,4]. Both often resolve with warm compresses (5-10 min, 4-5x/day) and lid massage. Persistent cases (>4-6 weeks) warrant referral to ophthalmology for assessment of comorbid eye conditions (e.g., rosacea keratitis, blepharitis) [4], and possible definitive management with antibiotics, steroids, and/or incision & curettage [3,5]. Good eyelid hygiene, including lid scrubs with baby shampoo, aids prevention [3–5].

Other common benign eyelid lesions include epidermal inclusion cysts, hidrocystomas, seborrheic keratoses and nevi

Cystic, non-ulcerated lesions that transilluminate may be sweat duct cysts (hidrocystomas), while non-transilluminating cysts may be epidermal inclusion cysts. Seborrheic keratoses appear greasy and “stuck on,” with variable pigmentation. Eyelid nevi may have little to no pigmentation, and the presence of protruding hairs is not uncommon.

Lifestyle Habits in Glaucoma: Practical Advice for Patients and Ophthalmologists

This article was authored by: Dr. Eileen Javidi, MD, Dr. Georges Durr, MD FRCSC and Dr. Younes Agoumi, MD FRCSC. The PRC Committee wish to acknowledge Félix Plamondon from the University of Laval for their initiative and contribution.

Patients suffering from glaucoma often seek advice on lifestyle changes such as exercise, diet, and other habits that may help them preserve their vision alongside conventional treatments. Although new research is emerging and our understanding of the complex pathophysiology of glaucoma is continuously growing, the relationship between lifestyle habits and glaucoma progression remains to be fully elucidated. This page aims to provide a clear and concise summary of the scientific data currently available, offering guidance for ophthalmologists when counseling their patients on lifestyle changes for glaucoma.


Exercise

Physical activity may be associated with slower rates of visual field loss in patients with glaucoma.1 Aerobic exercise, beyond its benefits for cardiovascular health, has also been shown to reduce IOP significantly. This effect is greater in previously sedentary people than in those who are already physically active.2 When a regular exercise regimen is adopted by previously sedentary individuals, IOP reduction may be sustained for longer periods of time (several weeks).3

Other studies have shown that strength training may increase IOP, particularly when holding one’s breath (Valsalva maneuver) while performing a weight-lifting exercise.4 On the other hand, some studies have found that resistance training may slightly decrease IOP in the minutes that follow the exercise.5 Since extensive research is still lacking, it may be safer to counsel patients to limit their resistance training to low or moderate intensities, to make sure to breathe out during the exercise and to avoid weigh- lifting altogether in moderate to advanced glaucoma.

Yoga, when practiced vigilantly through exercises involving relaxation and breathing techniques and while making sure to keep the head above the heart, appears to be safe and may even reduce IOP.6 However, glaucoma patients must be strongly advised to avoid handstands and head-down positions, as these are known to acutely increase IOP, up to doubling it.7,8

Sleep

IOP is higher during sleep and in the supine position, increasing to a greater extent in patients with glaucoma and more advanced disease.9 It is also higher in lateral decubitus in the dependent eye,10 and when sleeping face down with contact with a pillow.11 These effects may be mitigated by avoiding sleeping face down or on the side, and by adding a wedge pillow to elevate the head by 30 degrees.12

Diet and Supplements

Coffee increases IOP immediately after consumption,13 but the data on its long-term impact on IOP and risk of glaucoma remains conflicting. Caffeine consumption may be associated with an increased risk of developing glaucoma in individuals with family history of glaucoma, but no association has been found in those without family history.14 It seems reasonable for most patients to consume moderate amounts of caffeine, but greater intakes should be discouraged, particularly in those with high IOP, severe glaucoma and a positive family history.15

Ginkgo biloba extract has gained attention for its potential antioxidant and neuroprotective effects, and benefits on blood circulation. However, current data is inconclusive regarding effects on IOP and visual field progression in glaucoma.16

Smoking

A large retrospective study has shown that being a current or past smoker is associated with elevated IOP. This association is even greater in glaucoma patients.17

Marijuana

Marijuana has been discussed as a potential alternative treatment for glaucoma, as it reduces IOP for three to four hours following its consumption by inhalation. However, maintaining adequate IOP control using marijuana would require near-continuous use; therefore, using marijuana for controlling glaucoma is highly ill-advised given its numerous cognitive, respiratory, and other adverse effects such as impairment in functioning.18

Meditation

Mindfulness meditation has been found to lower IOP and can be used as adjuvant treatment to medical therapy for IOP control in glaucoma.19-21

Celebrating Black Excellence in Ophthalmology
Black History Month recognizes the significant contributions of Black individuals in various fields, including medicine. In ophthalmology, Black pioneers have made groundbreaking advancements in clinical practice, research, education, and advocacy. Their work has improved patient care while promoting diversity, equity, and inclusion in the field.

Pioneers in Ophthalmology


Dr. David K. McDonogh (c. 1821–1893)
Born into slavery, Dr. McDonogh pursued medical education after gaining his freedom and became one of the first Black physicians in the United States. He specialized in ophthalmology and dedicated his career to improving eye care for underserved populations while advocating for increased opportunities for Black medical students. 

Dr. Charles Victor Roman (1864–1934)
Dr. Roman was a pioneering ophthalmologist and educator who founded and chaired the Department of Ophthalmology and Otolaryngology at Meharry Medical College. Born to parents who were fugitive slaves, he overcame significant hardships to become a respected advocate for Black healthcare and medical education. 

Dr. Patricia Bath (1942–2019)
A trailblazing ophthalmologist, inventor, and academic, Dr. Bath was the first Black female physician to receive a medical patent for her invention of the Laserphaco Probe, which revolutionized cataract surgery. She was also the first Black female ophthalmology resident at NYU and co-founded the American Institute for the Prevention of Blindness. 

Dr. Maurice F. Rabb Jr. (1932–2005)
Dr. Rabb was a renowned ophthalmologist recognized for his work in cornea and retinal vascular diseases. As one of the first African American students at the University of Louisville, he later became the first Black chief resident at the University of Illinois Eye and Ear Infirmary. His leadership in ophthalmic research and education remains influential today. 

Dr. Howard P. Venable (1913–1998)
Dr. Venable played a pivotal role in desegregating hospitals and ophthalmology training programs. A dedicated mentor, he expanded opportunities for Black physicians in the field. His civil rights activism extended beyond medicine, as he fought against racial discrimination in housing and healthcare. 

Dr. Lois Young-Thomas
Dr. Young-Thomas was the first Black female graduate of the University of Maryland School of Medicine in 1960. She dedicated her career to serving disadvantaged communities and fostering medical education. She later became a professor and mentor, receiving numerous teaching awards for her contributions to ophthalmology education. 

Dr. Eve Higginbotham
A leader in academic medicine, Dr. Higginbotham became the first Black woman to chair an ophthalmology department in the United States at the University of Maryland. A glaucoma specialist, she has made significant contributions to research, healthcare policy, and diversity in medicine. 

Dr. Keith Carter
Dr. Carter is a distinguished leader in academic ophthalmology. As Chair of Ophthalmology at the University of Iowa and past president of the American Academy of Ophthalmology (AAO), he has championed diversity initiatives and mentored underrepresented medical students and residents. 

Dr. Fasika Woreta
A pediatric ophthalmologist and geneticist, Dr. Woreta is an Associate Professor at Johns Hopkins University. She has conducted significant research on congenital cataracts and retinal diseases in children while advocating for global pediatric eye care access and increasing diversity within ophthalmology. 

Conclusion
These individuals have left a lasting impact on the field of ophthalmology and beyond. Their perseverance, innovation, and advocacy continue to inspire future generations of physicians and researchers. As Black History Month is celebrated, their contributions are acknowledged, reaffirming a commitment to fostering diversity and equity in medicine.

CJO January 2025: Featured Highlights on Glaucoma

The following CJO Highlight summarizes key findings from the journal article “Acute Angle-Closure Glaucoma Risk: A Comparative Study of Escitalopram and Antidepressants.”1

Acute angle-closure glaucoma (AACG) is an ophthalmic emergency that has been linked to selective serotonin reuptake inhibitors (SSRIs) due to their mild anticholinergic effect and possibility of mydriasis. Escitalopram, one of the most prescribed SSRIs, has been implicated in the risk of AACG in case reports. However, prior to this CJO study by Khan et al., it remained unclear whether AACG secondary to escitalopram is a class effect or carries a higher risk than other SSRIs. The highlighted study investigated whether escitalopram poses a greater risk of AACG compared to other SSRIs or non-SSRI antidepressants. A total of 865,546 subjects were included to assess the incidence of AACG among new users of citalopram, escitalopram, sertraline, and venlafaxine. Results indicated trends toward a lower AACG risk in users of citalopram, escitalopram, and venlafaxine compared with sertraline, though none of these differences reached statistical significance. Findings suggest that escitalopram may be associated with a reduced risk of AACG, but further research with larger cohorts is needed. Clinicians should remain cautious when prescribing antidepressants, particularly for patients at risk of glaucoma.
