What are Oil Drop Cataracts?
Oil drop cataract is a type of central cataract where the opacity in the lens looks like a drop of oil. It is usually seen in the centre of the lens and gives a shiny, round appearance during eye examination.
This type of cataract is often linked with certain metabolic disorders. Early detection is very important in such cases
Causes of Oil Drop Cataracts
The most common cause is metabolic disease, especially galactosemia. In this disorder, the body cannot properly process galactose, a type of sugar. Because of this, substances accumulate in the lens and cause clouding. In affected babies, improper breakdown of milk sugar leads to deposition inside the lens.
Other possible causes include:
- Genetic factors
- Developmental lens abnormalities
- Rare systemic metabolic conditions
Unlike age-related cataract, this type is not mainly due to ageing. It is more commonly seen in infancy or early childhood when related to metabolic problems.
If galactosemia is diagnosed early and diet is controlled, the progression of cataract may be reduced

Symptoms
Symptoms of Oil Drop Cataracts
In infants, parents may notice:
- White reflex in the pupil
- Poor fixation on faces
- Excessive eye movements
- Delay in visual response
In older children, symptoms may include:
- Blurred vision
- Difficulty reading
- Squint
- Frequent change in glasses
Because the opacity is central, it directly affects the visual axis. That is why even small oil drop cataracts can disturb vision.
Treatments
Treatment Options for Oil Drop Cataracts
- Clouded, blurred, or dim vision.
- Difficulty seeing at night.
- Increased sensitivity to light and glare.
- Need for brighter light for reading and other activities.
- Seeing “halos” around lights.
- Frequent changes in eyeglass or contact lens prescription.
- Fading or yellowing of colors.
- Double vision in one eye.
In most central cataracts affecting infants, surgery is required early to prevent lazy eye.
Cataract surgery involves the removal of the cloudy lens. In older children, intraocular lens implantation may be done. In very young infants, doctors may prefer contact lenses after lens removal.
If galactosemia is the cause, strict dietary management is essential. Removing galactose from the diet can sometimes stop further progression.
How is Oil Drop Cataracts Diagnosed?
Diagnosis is done through a detailed eye examination by an ophthalmologist. In babies, red reflex testing helps in early detection.
After dilating the pupil, the doctor examines the lens using a slit lamp. A central, round opacity resembling an oil drop is seen.
If a metabolic disorder is suspected, blood and urine tests are advised.
How to Prevent Oil Drop Cataracts?
Important steps include:
- Newborn screening for galactosemia
- Early paediatric evaluation if the baby shows feeding problems
- Genetic counselling in families with a history
- Regular eye check-up in high-risk infants
Proper diet control in metabolic disorders can reduce the severity of cataract.
Conclusion
Oil drop cataract is a central lens opacity often linked to metabolic disorders like galactosemia. It usually affects infants and young children. Because it blocks the visual axis, early treatment is important. Parents should not ignore white reflex or poor visual response in babies. Early action helps protect vision.
Frequently Asked Questions:
About Oil Drop Cataracts
What are the early symptoms of Oil Drop Cataracts?
Early symptoms include white reflex in the eye, poor eye contact in babies, and blurred vision in older children
At what age do Oil Drop Cataracts usually develop?
They are commonly seen in infancy or early childhood, especially in metabolic conditions like galactosemia.
What is the best treatment for Oil Drop Cataracts?
If vision is affected, cataract surgery is the best treatment. In metabolic cases, dietary control is also very important.
When is surgery required for Oil Drop Cataracts?
Surgery is required when the central opacity blocks vision and interferes with visual development. Early surgery is important in infants.
How long is the recovery after surgery for Oil Drop Cataracts?
Initial healing takes a few weeks. However, visual rehabilitation may continue for months with regular follow-up.
What type of lens is best for Oil Drop Cataracts?
In older children, intraocular lenses are used. In very young infants, contact lenses may be preferred. The choice depends on age and eye condition.
Can Oil Drop Cataracts be prevented?
Some cases related to metabolic disorders can be managed with early diagnosis and proper diet control. Genetic causes cannot always be prevented.
Does diabetes increase the risk of Oil Drop Cataracts?
Diabetes is not a common cause of oil drop cataract. It mainly causes other types of cataract seen in adults.
