T-Sign-OD Eye Drops 5 ml belongs to a class of anti-hypertensive drugs called 'beta-blockers' primarily used to treat increased pressure in the eye in conditions of glaucoma (damage of optic nerve) and ocular hypertension (high fluid pressure inside the eye). Glaucoma is an eye condition which causes damage to the optic nerve (essential for good vision) due to abnormally increased pressure in the eye. Ocular hypertension is increased pressure in the eye due to poor drainage of aqueous humour (fluid in the eye that maintains normal pressure by its continuous flow).

T-Sign-OD Eye Drops 5 ml works by decreasing the secretion of aqueous humour (a liquid that maintains normal pressure in the eyeball) by the ciliary body into the eyeball. Thereby lowers the pressure in the eye by reducing aqueous humour entry into the eyeball.

• Avoid intake of baked foods such as cakes, cookies, donuts or fried items such as French fries and stick margarine as these foods may worsen glaucoma and damage optic nerve.
• Cut down your coffee intake as it may increase pressure in the eye and replace coffee with green tea.
• Avoid exercises such as any position where head is lower than body like inverted yoga pose as it may increase pressure in the eye. Doing selective exercises is advised for glaucoma patients.

• T-Sign-OD Eye Drops 5 ml should be used with extreme caution in children and if you notice abnormal breathing, wheezing, coughing or unusual pauses in breathing, stop using T-Sign-OD Eye Drops 5 ml and consult a doctor immediately.

• Routine eye tests are recommended at least every 2 years to detect glaucoma as it does not show any symptoms initially.

Glaucoma: It is an eye condition that causes damage to the optic nerve (essential for good vision) due to abnormally increased pressure in the eye. If it is not treated in time, it may cause blindness. Usually, there are no symptoms of glaucoma initially except the slow loss of vision gradually. However, some symptoms include visible rainbow-colored circles around bright lights or blurred vision. Rarely, glaucoma can develop suddenly with intense pain in the eye, visual disturbance, or nausea. Ocular hypertension is a condition caused due to poor drainage of aqueous humor (fluid in the eye that maintains normal pressure by its continuous flow). This leads to the build-up of excess fluid in the eye resulting in increased pressure inside the eye without any damage to the optic nerve. If ocular hypertension is not controlled, it may lead to glaucoma.
