Coloboma is a condition that occurs from birth, affecting one or both eyes. This eye condition occurs when part of the tissues in the eye is missing.
If you have a child with coloboma, consult your doctor about the best care plan, as some treatments are available to help make the most of vision.
There are different types of coloboma affecting different parts of the eye. They include:
Coloboma may not cause any symptoms, but some people experience problems with their vision, such as:
Some colobomas are visible, like the iris coloboma, that make the pupil look like a teardrop or keyhole.
Coloboma occurs when a baby's eye develops abnormally during pregnancy due to changes or abnormal genes that interfere with eye development. Coloboma may run in families. Factors such as drinking during pregnancy may also increase the risk of coloboma.
Coloboma usually occurs with conditions affecting different body parts, like Wolf-Hirschhorn and CHARGE syndrome.
Sometimes, coloboma is visible when a baby is born, so the doctor may diagnose the condition by examining the baby's eyes. If the coloboma is not visible, the doctor by carry out a comprehensive dilated eye examination.
No treatment is available to replace part of the missing eye tissue resulting from coloboma, but treatments can help people with the condition make the most of their vision. They include:
People with coloboma resulting in refractive errors may require contact lenses or eyeglasses for better vision. People with iris colobomas can make their pupils look rounder by wearing coloured contact lenses.
Iris colobomas may need surgery to make the pupils look rounder. Your doctor can inform you about available options if you are concerned about your eye's appearance.
If coloboma results in vision loss that contacts or glasses cannot correct, you can use special devices for better vision. A low-vision specialist can help determine the most suitable devices for you and teach you how to use them.
Children with coloboma in only one eye may need an eye patch or special eye drops to prevent lazy eye or amblyopia.
Adults and children may require treatments for other eye conditions related to coloboma, such as:

I had an absolutely wonderful experience doing Lasik at this clinic. Their entire staff was extremely professional and courteous throughout the entire process.
My surgeon was wonderful, made me feel entirely at ease before and during surgery. Highly recommended.
Laser eye surgery, now glasses free after 23 years! :)
I have always thought about laser, I have worn glasses for 23 years. I was very anxious, worried about the what ifs. I had an appointment with Dr Mani, he explained everything to me and I decided to go ahead with the surgery. It was so fast, Dr Mani did remind me to be patient and I think this is very important. I am now glasses free and hoping this will continue! After care was good, a week after surgery I was concerned and Dr Mani invited me down to check my eyes to be sure all was ok. Thank you
LASIK with Dr. Mani
I had LASIK surgery with Dr. Mani. It was painless, smooth, and everything went well. The staff and Dr. Mani are all friendly and will answer all questions asked. Will recommend 100%! Thank you!
I had a great experience performing my laser eye surgery at Optimal Vision Clinic. All the staffs are very helpful, co-operative and supportive throughout the treatment process. On the first call, they explained the entire procedure in details and gave necessary instructions at every stage. My eye surgeon made me feel comfortable and relaxed before and during the procedure. Aftercare was done properly with a thorough check-up of my eyes. I would like to recommend this clinic to everyone!
Very happy and impressed with the highly professional care and service I’ve received at the Optimal Vision clinic. Dr Mani is so professional, and he explained everything about Laser surgery and answered all my questions. The surgery was quick and almost completely painless. My eyes have healed perfectly and quickly. I would highly recommend this clinic.
My husband had been experiencing discomfort in his left eye since July and was seen by various doctors/consultants even at the Queen Mary’s hospital but no abnormalities were found.
This week Dr. Mani discovered the fault which happened to be Retina detachment with three tears.
Dr. Mani’s preciseness and his perfectionist attitude to attention to details, detected the source of the main issue and saved my husband’s eye. We feel utterly grateful and can not recommend him enough for his excellence.
