The Effect of Combination of Vitamin A, Vitamin E, Sodium Hyaluronate 0.15% Eye Drop Compared With Sodium Hyaluronate 0.1% Eye Drop to Tear Film Stability and Conjunctival Goblet Cells Density in Patient With Non-Proliferative Diabetic Retinopathy (NPDR), and Proliferative Diabetic Retinopathy (PDR)
June 26, 2019 updated by: Made Susiyanti, Dr Cipto Mangunkusumo General Hospital
Commonly know that one of the complications caused by Diabetes Mellitus (DM) is microangiopathy.
Microangiopathy in the long term may lead to neuropathy of the corneal nerves.
Neuropathy of the cornea will lead to dry eyes in DM patient.
One of the artificial tears used in treating dry eyes is sodium hyaluronate.
But until recently no research had been done in examining the effect of giving combination of sodium hyaluronate, vitamin A and vitamin E in dry eyes.
The antioxidant, and capability of vitamin A and E in promoting cell proliferation may alleviate the symptoms of dry eyes.
In this paper we used Ocular Surface Disease Index (OSDI), Tear Break Up time, Schirmer I test and impression cytology to assess baseline and 28 days post therapy in patient with Non-Proliferative Diabetic Retinopathy (NPDR), and Proliferative Diabetic Retinopathy (PDR)

Detailed Description
The study is double blind randomized clinical trial, comparing the usage of combination of sodium hyaluronate 0.15%, vitamin A and vitamin E eye drops compared to sodium hyaluronate 0.1% eye drop only in patient with NPDR or PDR with decreased corneal sensitivity.
The examination consisted of OSDI questionnaire, tear film break up time, Schirmer I, and goblet cell density, examined at baseline and 4 weeks (day 28) after the initial eye drops is given.
For sample size calculation, estimated 96 patients are required to give statistical effect, this number already calculating the possibility of 20% drop out rate.
Every eligible patient is then randomized with block randomization into each allocated arm.
Statistical analysis used for this study is unpaired T test if the data distribution is normal, if not Mann-Whitney test will be used.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Ocular Surface Disease Index (OSDI) questionnaire
Time Frame: 4 weeks
|
A questionnaire to measure subjective symptoms of dry eyes.
Possible score of 0 (no dry eye) to 100 (severe dry eye).
Measured at baseline, day 14 and day 28.
|
4 weeks
|
Tear Film Breakup Time
Time Frame: 4 weeks
|
Measurement in seconds of tear film stability.
The shorter the fluorescein tear break up time, the lower the tear film stability.
Measured at baseline and day 28.
|
4 weeks
|
Schirmer I Test
Time Frame: 4 weeks
|
Measurement of tear production.
The amount of tears are measured in total millimeters after 5 minutes has elapsed.
Measured at baseline and day 28.
|
4 weeks
|
Conjunctival Goblet Cell Density
Time Frame: 4 weeks
|
Measurement of conjunctival goblet cell count per mm2.
Measured at baseline and day 28.
|
4 weeks
