Abstract.
This study compares the effectiveness of topical dexamethasone and artificial
tear drops in treating viral conjunctivitis. Dexamethasone provides rapid relief of inflammation
but requires cautious use due to possible side effects. Artificial tears are safe for long-term use,
reducing discomfort and supporting ocular surface hydration. Both approaches show benefits,
and individualized or combined treatment may yield optimal outcomes.

inflammation; symptomatic treatment.
Introduction
Viral conjunctivitis is one of the most common inflammatory diseases of the ocular
surface, with a high prevalence among both children and adults. The condition is most often
associated with adenoviruses and manifests with symptoms such as eye redness, burning
sensation, tearing, and temporary visual impairment. It significantly affects patients’ quality of life
and, due to its contagious nature, also represents an important public health concern. The
management of viral conjunctivitis is mainly symptomatic. In this regard, topical dexamethasone
drops may reduce inflammation and provide faster clinical improvement, whereas artificial tear
drops play an important role in moisturizing the ocular surface and relieving discomfort. This
clinical study is aimed at comparing the effectiveness of these two therapeutic approaches in the
treatment of viral conjunctivitis.
Main part
Viral conjunctivitis is one of the most common inflammatory diseases of the ocular
surface, primarily caused by adenoviruses. It presents with redness, swelling, tearing, irritation,
and temporary visual impairment, which significantly impacts patients’ quality of life. The disease
is highly contagious and can spread rapidly in schools, kindergartens, and other crowded
environments, posing not only an individual health problem but also a public health concern. Due
to its wide prevalence and negative impact, finding effective treatment strategies remains a
priority in ophthalmology.
Currently, there is no specific antiviral therapy widely used for viral conjunctivitis.
Management is largely symptomatic, focusing on relieving discomfort and controlling
inflammation. Common therapeutic options include topical corticosteroids and artificial tear
drops. Corticosteroids primarily target inflammation, leading to rapid improvement in clinical
signs, while artificial tears maintain hydration of the ocular surface and reduce irritation. Both
approaches are effective, but they differ in their mechanism of action and clinical outcomes, which
makes comparison between them important in practice. Dexamethasone is a potent corticosteroid
with strong anti-inflammatory properties. In cases of viral conjunctivitis, it helps suppress the
inflammatory response in the conjunctiva, resulting in quick relief from redness, swelling, and
irritation. This rapid reduction of symptoms improves patient comfort and facilitates recovery.

However, prolonged use of corticosteroids carries potential risks, such as secondary infections and
increased intraocular pressure, which is why they must be used cautiously under medical
supervision. Despite these limitations, dexamethasone remains an important therapeutic option for
controlling acute inflammatory symptoms.
Artificial tear drops play a key role in supporting the natural protective mechanisms of the
eye. In viral conjunctivitis, dryness and instability of the tear film worsen discomfort and
irritation. Artificial tears help restore ocular hydration, flush out inflammatory mediators and viral
particles, and create a protective layer over the ocular surface. Their use reduces burning and
foreign div sensation, while being safe for long-term application. Unlike corticosteroids, they do
not carry significant risks, which makes them a reliable symptomatic treatment option for many
patients. The primary aim of this clinical study is to compare the therapeutic effectiveness of
topical dexamethasone and artificial tear drops in patients with viral conjunctivitis. The study
seeks to determine their respective strengths and limitations in relieving symptoms and improving
recovery. It is expected that dexamethasone will provide faster control of inflammation and visible
signs of the disease, while artificial tears will ensure better comfort and ocular surface protection.
The findings may help clinicians choose the most appropriate or combined treatment approach,
leading to more effective patient care in clinical practice.
Conclusion
The comparative evaluation of topical dexamethasone and artificial tear drops in the
treatment of viral conjunctivitis highlights their complementary roles. Dexamethasone provides
rapid suppression of inflammation, effectively reducing redness, swelling, and irritation, but
requires careful monitoring due to potential side effects. On the other hand, artificial tear drops
offer safe and well-tolerated symptomatic relief by moisturizing the ocular surface and improving
patient comfort, particularly for long-term use. The findings suggest that both treatments can be
effective depending on clinical presentation, and in some cases, a combined or sequential
approach may yield optimal results. This underscores the importance of individualized treatment
strategies in managing viral conjunctivitis.
