About this study
Official title: 3% Diquafosol Topical Ophthalmic Solution in Diabetic Patients With Dry Eye
Diquafosol ophthalmic solution (DQS) stimulates P2Y2 receptors on the ocular surface, which enhances mucin secretion from goblet cells. Therefore, tear film stability and hydration of the ocular surface can be achieved independent from lacrimal glands function. This prospective, open label pilot study will include 140 eyes of 70 diabetic patients diagnosed with DED and will be consecutively assigned to DQS (n=140 eyes). Participants in the DQS group will receive 3% Diquafosol ophthalmic solution. The dosage of 3% Diquafosol will be one drop, six times per day for 4 weeks. Tear film lipid layer (TFLL), non-invasive breakup time (NITBUT), corneoconjunctival staining score (CS), meibum gland (MG), conjunctival hyperemia (RS score), ocular surface disease index (OSDI) will be assessed and compared at baseline, day-14, and day-28.
Read the detailed description
This study will be conducted in compliance with the tenets of the Declaration of Helsinki and the Institutional Review Board of He Eye Specialist Hospital, Shenyang, China [ethics approval number: IRB(2022)K002.01]
Type 2 diabetes mellitus (T2DM) is a prevalent chronic metabolic illness that causes relative insulin insufficiency in target organs owing to pancreatic β-cell dysfunction and insulin resistance. Shift to sedentary lifestyle, ageing population and obesity has significantly contributed to the global rise in the prevalence of T2DM. In 2019 the prevalence of diabetes was documented to be 9.3% (463 million people) and in 2030 it is estimated to rise to 10.2% (578 million) and T2DM accounts for approximately 90% of all diabetic occurrence. Negative alterations to the tear film, corneal epithelium, corneal endothelium, and corneal nerves have been observed in 47-64% of patients with diabetes. Ocular surface manifestation of signs and symptoms secondary to DM has been termed as diabetic keratopathy (DK). DK has been documented to increase central corneal thickness[6], decrease in endothelial cell density, leads of superficial punctate keratitis[8], delay and impede wound repair[9], and decrease in corneal sensitivity due to neuropathy. Additionally, DM patients have also been noted to have compromised tear quantity and quality due to conjunctival goblet cell loss as documented on cytologic analysis. Goblet cells secrete mucin, which stabilizes the tear film, minimizes tear evaporation, and reduces mechanical friction. Goblet cell loss in animal models suggests that it disrupts the ocular surface's immune tolerance and increased expression of inflammatory cytokines in the conjunctiva. 0.1% hyaluronate (HA) used in artificial tears have been reported to promote corneal re-epithelium and improve corneal healing.
Diquafosol tetrasodium is a dinucleotide polyphosphate which a purinoceptor agonist, when administered to the ocular surface, it binds to P2Y2 receptors and stimulates mucin and tear secretion. The corneal epithelium, conjunctival epithelium, lacrimal gland ductal epithelium, meibomian gland sebaceous cells, and meibomian gland ductal cells all express the P2Y2 receptor. Subsequently, enhanced secretion of mucin and tear secretion due to Diquafosol tetrasodium ophthalmic solution (DQS) stabilize the tear film, minimizes tear evaporation, and reduces mechanical friction thereby protecting the corneal epithelium [23]. Various reports have concluded that that 3% DQS is effective in the treatment of dry eye disease and the year 2020's findings suggest that DQS improves corneal epithelial damage in T2DM rat model.
However, the effect of DQS on the tear film of T2DM humans has not been previously assessed. Therefore, the purpose s to assess subjective and objective diabetic dry eye findings after using 3% DQS topical eye drops.

What is being measured
The primary outcome is the main question the study is designed to answer.
Non-invasive tear break-up time
Non-invasive initial tear film breaking time will be assessed using the Keratograph 5M (Oculus, Germany) topographer. Three sequentially readings will be captured, and the median value will be included in the final analysis. The median value will be recorded.
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Secondary outcomes (9)
Fluorescein and lissamine conjunctival and cornea staining
Fluorescein and lissamine staining of the ocular surface will be divided into three zones comprising nasal conjunctival, corneal, and temporal conjunctival areas. The staining score ranged from 0 to 3 for each zone, yielding a total score of 0-9 for the ocular surface (Uchino et al., 2012).
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Tear Film Lipid Layer Score
Tear Film Lipid Layer interferometry will be assessed using DR-1 (Kowa, Nagoya, Japan).
- Tear Film Lipid Layer will be scored as follows: grade 1, somewhat gray color, uniform distribution; grade 2, somewhat gray color, nonuniform distribution; grade 3, a few colors, nonuniform distribution; grade 4, many colors, nonuniform distribution; grade 5, corneal surface partially exposed.
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Corneal Sensitivity Score
Corneal Sensitivity Score measured with Cochet-Bonnet esthesiometer (in mm filament length) two times (the measurements will be done immediately before starting the medication, including 3 measurements each time.
Measured: Day-0 (baseline), 4-weeks and 8-weeks
MMP-9 detection
InflammaDry, (Rapid Pathogen Screening Inc., Sarasota, FL, USA) is a patented and proprietary modification of a traditional lateral flow device and uses direct sampling microfiltration technology. Two antigen-specific antibodies capture MMP-9 antigens in the sample, and this complex is captured in a proprietary mode at the test result line, giving rise to a visually observable signal.
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Tear meniscus height
Non-invasive first tear film breakup time using the Keratograph 5M (Oculus, Germany) topographer will be measured three times consecutively and the median value was recorded. of the three values was calculated.
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Conjunctival hyperemia (RS score)
Conjunctival hyperemia (RS score) will be assessed by keratograph image (Oculus, Germany) of 1156*873 pixels, redness score (RS) (accurate to 0.1 U) was displayed on the computer screen that ranged from 0.0 to 4.0.
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Meibomian gland function and secretion quality
Meibum quality will be assessed under a slit-lamp:
Five meibomian gland in the middle parts of the eyelid will be assessed using a scale of 0 to 3 for each gland (0 represented clear meibum; 1 represented cloudy meibum; 2 represented cloudy and granular meibum; and 3 represented thick, toothpaste like consistency meibum).
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Corneal nerves and immune/inflammatory cells change
HRT III RCM, (Heidelberg Engineering GmbH, Dossenheim, Germany) will be used to record corneal nerves and immune/inflammatory cells change. A total of 5-8 sequence/volume scans were taken from the center of each cornea, focusing on all corneal layers: superficial, intermediate, and basal epithelial layers, sub-basal nerve plexus, anterior, central and posterior stroma, and endothelium. Special attention was given to the basal epithelial layer and sub-basal nerve plexus area to evaluate the nerve plexi and epithelial DC density. Three representative images of the sub-basal nerve plexus and epithelial DCs were selected for analysis for each eye, considering criteria such as whole image in the same layer, best focus and good contrast.
Measured: Day-0 (baseline), 4-weeks and 8-weeks
Dry eye Questionnaire Score
Chinese translated version of the questionnaire will be used to assess the subjective dry eye symptoms.
Measured: Day-0 (baseline), 4-weeks and 8-weeks

This prospective, open label pilot study will include 140 eyes of 70 diabetic patients diagnosed with DED and will be consecutively assigned to DQS (n=140 eyes). Participants in the DQS group will receive 3% Diquafosol ophthalmic solution. The dosage of 3% Diquafosol will be one drop, six times per day for 4 weeks.
