New reports show Taxotere could cause eye injuries and vision damage to users.
Taxotere Vision Damage Lawsuits allege that Sanofi, the pharmaceutical company who manufactures the chemotherapy drug, failed to provide an adequate warning for eye injury and excessive tearing.

The lawsuit claims that Taxotere use may result in excessive tearing, watery eyes, lacrimal duct obstruction, and potentially permanent damage to eyesight.
Sanofi has denied knowing about the risks of vision loss or permanent watery eyes.
Taxotere Eye Injury
Taxotere impacts the lacrimal system, the bodily system that includes tear ducts and the structures responsible for tear production and drainage.
Taxotere enters into the tear film, and build-up of the drug may lead to scarring of the lacrimal system and permanent occlusion (blockage).
If left untreated, affected individuals might not be able to drain tears naturally, leading to the excessive tearing, “Epiphora”, watery eyes, other health effects, and the potential need for corrective surgery.

Multiple eye injuries can result from prolonged Taxotere use, experts say.
Taxotere eye injuries include:
- Canalicular stenosis
- Punctal stenosis
- Nasolacrimal Duct Obstruction
- Excessive tearing or eye-watering (epiphora)
- Permanent watery eyes
- Conjunctivitis or blockage of the tear ducts/lacrimal system
- Scarring of lacrimal system
- Blurred vision
- Swollen eyelids
- Eye infections and irritations
- Increased sensitivity to light
- Headaches
- Potential loss of vision (cystoid macular edema)
These symptoms and/or side effects can heavily affect the daily activities of patients, hampering abilities such as driving, reading, and any vision related task one may perform at a job.
Taxotere’s side effects can severely impact an individual’s quality of life.
Canalicular Stenosis and Punctal Stenosis
Tear film ensures hydration and washes away dust and particles in the eyes.
Tears then travel through small canals, called the Canaliculus, into the nasolacrimal duct.
Canalicular Stenosis is obstruction of the Canaliculus, which prevents tears from flowing through the lacrimal system and forces them to well up in the eyes and cause excessive tearing and eye watering.
Punctal Stenosis refers to obstruction of the punctum: small openings located in the upper and lower eyelids that connect to the canaliculus.
Stenosis onsets quickly, but is preventable with early intervention.
Stenosis is more common in breast cancer patients taking Taxotere in weekly regimens than regimens that are every three weeks.
Through scientific studies, Taxotere was found to be secreted into patients’ tear film.
Taxotere damages the canaliculus through fibrosis or scarring, and leads to the aforementioned eye disorders.
Corrective Surgeries for Canalicular Stenosis and Punctal Stenosis
Canalicular Stenosis and Punctal Stenosis caused by Taxotere can necessitate serious surgical operations.
A clinical study conducted at the University of Texas M.D. Anderson Cancer Center (Houston) involved ten metastatic breast cancer patients with canalicular stenosis and epiphora caused by docetaxel.
All ten patients underwent either of the following surgeries to correct their condition:
- Bicanalicular silicone intubation: Dilation or maintenance of canaliculi by probing or using stents. (seven patients)
- Canaliculo Dacryocystorhinostomy (DCR) with the Placement of a Silicone Tube (one patient) or Conjuctivo DCR with the Placement of a Glass Tube (two patients): Creation of a new passage for tear drainage by inserting bypass tubes. Can be completed through an external minimally invasive surgical procedure or an endoscopically (through the nose).
Nasolacrimal Duct Obstruction
Nasolacrimal Duct Obstruction refers to the same sort of scarring and occlusion as is experienced with Canalicular Stenosis, but in the deeper ducts and canals of the lacrimal system.

The lacrimal system is the base for dealing with tear production and drainage.
This condition can cause severe eye injuries and vision issues.
Permanent Stenosis
Canalicular Stenosis and Punctal Stenosis can become irreversible.
As breast cancer patients are often overwhelmed with other health issues and side effects related to their recovery, they may not pay as close attention to excessively watery eyes.

If Canalicular Stenosis or Punctal Stenosis is left untreated, the ailment can become permanent.
Given the speed at which these conditions worsen, time is of the essence in keeping yourself safe and managing your condition.
Epiphora
Epiphora is excessive tearing or watery eyes.
Scarring or fibrosis of tear ducts and the canaliculus can cause tears to well-up, remain on the eye, and run down the face.

Chronic watery eyes are bothersome to patients and can lead to further eye injuries.
Misdiagnosis of Taxotere Eye Injuries
As a person is recovering from cancer and going through chemotherapy, it can be difficult to pinpoint the causes of certain side effects.
One may think that persistent watery eyes are caused by allergies or immune system deficiencies.
Eye injuries and disorders resulting from Taxotere use are often misdiagnosed by doctors and opthamologists as allergies, minor eye conditions, or symptoms of other ailments.

It’s important to contact a lacrimal specialist or an ocular plastic surgeon, a doctor who focuses on the tear duct system, as soon as possible if you notice excessively watery eyes after Taxotere doses.
