เมื่อไหร่ที่คนไข้โรคตาแห้ง ควรใช้น้ำตาซีรั่ม

Recently, the Department of Ophthalmology, Faculty of Medicine, Chulalongkorn University, surveyed a group of Thai people aged 50-90 years and found that 14.21% of this group had dry eye disease. Dry eye disease varies in severity, so treatments differ. However, one increasingly popular method is the use of serum eye drops.
&nbsp;
<h4 style="text-align: left;">Treatment of Dry Eye Disease with Serum Eye Drops</h4>
Serum eye drops are made from the patient&#8217;s blood, which has biological properties similar to natural tears. Therefore, they are effective in treating dry eyes and are widely used in various hospitals.
&nbsp;
Ophthalmologists consider different concentrations and preparation methods for serum eye drops, but the most commonly used is 20% Autologous Serum Eye Drops because it contains growth-stimulating substances close to natural tears, making it effective for severe dry eye disease and ocular surface diseases.

<h4 style="text-align: left;">Who is Suitable for Serum Eye Drops? What are the Indications?</h4>
Ophthalmologists consider using serum eye drops for patients with severe dry eye disease and various ocular conditions as follows:
<ol>
<li style="text-align: left;">Severe dry eye syndrome that has been fully treated with artificial tears or has undergone procedures such as punctal occlusion but without success, or is associated with Sjögren&#8217;s syndrome, etc.</li>
<li style="text-align: left;">Ocular surface disease including severe allergic reactions like Stevens-Johnson syndrome and ocular inflammation such as Ocular Cicatricial Pemphigoid (OCP)</li>
<li style="text-align: left;">Persistent Epithelial Defect where corneal wounds heal slowly, such as in diabetic patients, herpes infections, shingles, or after corneal transplant surgery</li>
<li style="text-align: left;">Other patient groups such as severe dry eye syndrome following stem cell transplantation, chronic corneal wounds after eye surgery, etc.</li>
</ol>

Patients with severe dry eye symptoms or those diagnosed with Sjögren's syndrome, ocular surface disease, incomplete corneal epithelial closure, or slow-healing corneal ulcers, when other treatments are ineffective, ophthalmologists may consider using serum tears.
