Dry Eye Diagnosis Dry Eye Research association 1995 Dry Eye is disease of epithelium brought by quantitative and qualitative abnormality of tear film. ① Shirrmer’s Test : Less than 5mm （５ min.) 2. Abnormity of tear film ② Tear Break-Up time; Less than 5sec. 3. Abnormity on ① Fluorescein stain score （ Cornea + Conjunctiva): epithelium More than 3 points out of 9 points ② Rose-Bengal stain score; More than 3 points out of 9 points All １，２，３ are abnormal ⇒ Dry Eye 2 out of １，２ or ３ ⇒ Dry Eye Suspicious MENU 2010 TOPCON CORPORATION All right reserved
Dry Eye Diagnosis Dry Eye Research association 2006 Dry Eye is chronic disease of epithelium and tear film cased by several factors, and it brings on abnormity of visual performance or discomfort of the eye. Changed as below 1.Syndrome abnormity of visual performance or discomfort of the eye （ positive). ① Silmer Test : Less than 5mm （５ min.) 2. Abnormity of tear film ② Tear Break-Up time; Less than 5sec. ① Fluorescein stain score （ Cornea + Conjunctiva): 3. Abnormity on epithelium More than 3 points out of 9 points All １，２，３ are abnormal ② Rose-Bengal stain score; More than 3 points out of 9 points ⇒ Dry Eye ③ Acid Green Stain Score 2 out of １，２ or ３ More than 3 points out of 9 points ⇒ Dry Eye Suspicious MENU 2010 TOPCON CORPORATION All right reserved
◆ Shirrmer’s test … For the Dry Eye diagnosis, it is examined to find how much amount of tear is shorter than normal. It is normal when filter paper, hold in bottom lids, hydrated more than 10 mm in 5 minutes, but it is diagnosed to be dry eye when the paper hydrated less than 5 mm. Shirrmer’s test 2010 TOPCON CORPORATION All right reserved
◆ Fluorescein Stain …To see scar existence on the cornea and conjunctiva. ◆ Rose-Bengal Stain …To see condition of the cornea and conjunctiva with the Rose- Bengal Stain. This stains red where mucin layer is not exist and dry, and it reveal where the tear film is dried out in the cornea and conjunctiva. ◆ Acid Green.. To stain transformed epithelium ◆ Fluorescein Stain …To see scar existence on the cornea and conjunctiva. ◆ There are other tests to examine tear film stability or meibomian gland.

Current Dry Eye examination equipment issue • No instrument is able to evaluate dry eye with new criteria. No product can evaluate visual performance right now. • DR-1 ： – The DR-1 shows Oil film BUT （ Break-Up Time), but it is qualitative. – The DR-1 cannot evaluate visual performance. 2010 TOPCON CORPORATION All right reserved
