Oculoplasty
Tears are produced by the lacrimal gland located in the upper outer portion of each eye. They normally drain from the eye through small tubes called tear ducts or nasolacrimal ducts( NLD) that stretch from the eye into the nose. A blocked tear duct occurs when the opening of the duct that normally allows tears to drain from the eyes is obstructed or fails to open properly. If a tear duct remains blocked, the tear duct sac fills with fluid and may become swollen and inflamed, and sometimes infected.
Nld Block(nasal lacrimal duct)
In babies, the most common cause of NLD Block is the failure of the thin tissue at the end of the tear duct to open normally.
Other less common causes of NLD Block in children include:
1. Infections.
2. Abnormal growth of the nasal bone that puts pressure on a tear duct and closes it off.
3. Closed or undeveloped openings in the corners of the eyes (puncta) where tears drain into the tear ducts.
In adults, tear ducts may become blocked as a result of a thickening of the tear duct lining, nasal or sinus problems, injuries to the bone and tissues around the eyes (such as the cheekbones), infections, or abnormal growths such as tumors.
Diagnosis
Diagnosis is based on symptoms. The cause of the tear duct blockage must also be identified. Tests are determined by the patient’s age and symptoms. To determine the presence and extent of tear duct blockage, a fluorescein eye stain is used to observe the drainage of tears. An orange dye is placed in the eye using a dropper or blotting paper. After it covers the surface of the cornea, a blue light is shone on the eye to detect abnormalities on the cornea, including delays in tear drainage.
An internal examination of the nose may be indicated, especially if an injury has occurred. Imaging tests and x-rays also may be warranted to rule out other causes, such as a tumor. In adults, a fluid is irrigated through the nasolacrimal drainage system to locate and determine the extent of the blockage.
For children lacrimal sac massage, antibiotic drops and if still not improving then syringing and probing under GA.
For Adults surgery is the option according to the syringing results of both upper and lower punctum.
We manage other diseases as well like Ptosis, Ectropion, Entropion and other Oculoplasty related diseases.
