Getting to Know Dr Teoh Charn Beng Stephen

Getting to Know Dr Teoh Charn Beng Stephen

Q: What kind of conditions do you treat, or specialise in treating?

I specialise in both surgical retina (including repair of retinal detachment and macular holes and surgery for diabetic eye disease, etc.) and medical vitreoretinal diseases such as age-related macular degeneration, retinal vascular disorders, and diabetic retinopathy. #readmore

I am also trained in the diagnosis and management of ocular inflammatory diseases, including potent anti-inflammatory drugs and drugs to suppress the immune system. I am also well-versed in comprehensive general ophthalmology, including complex cataract surgeries and presbyopic correction with the most advanced and modern wavefront, toric and multifocal lens implants, as well as refractive surgery including LASIK.

Q: Do you perform any kind of special treatments? If so, please share a little here.

I specialise in the care of patients with eye infections including HIV-related and dengue related eye diseases, amongst other common eye infections. #readmore

In the management of ocular inflammation and its complications, I can combine surgical retinal techniques that include sampling of the gel in the eye (vitreous biopsy) and of the light-sensitive nerve layer of the eye (chorioretinal biopsy). Examples include the clearing of media opacities in intermediate uveitis, management of complicated cataracts due to uveitis, and the diagnosis of posterior inflammation such as lymphoma.

Q: Could you share your philosophy in treating patients?

I believe that every person is a unique individual, made in the image of God, and is to be given the utmost honour and dignity.  As such, I want to listen carefully to everything my patient says. Everything a patient says is to be respected.  As a doctor and a surgeon, I want to give each precious person the best care to enhance their vision and quality of life. #readmore

The patient always comes first! People and their concerns and needs should always be at the centre of the medical system. As an eye surgeon I get a great sense of joy in meeting people, showing respect to every person. I am committed to giving each patient the best medical diagnosis and surgical skill in the care of a person’s eyes and vision.

Q: Briefly describe a particularly difficult case that you successfully treated using your expertise.

A middle-aged woman was referred to me with gradually deteriorating vision. She was previously treated for inflammation of the back part of the uvea (middle layer of the eye) with no improvement. #readmore

Initial diagnostic tests performed by the referring doctor including small amounts of intraocular fluid analysis returned negative. She was found to have large lesions in the back of the eye (choroid layer) that led to a clinical suspicion of a rare ocular tumour (lymphoma). Initial formal surgical biopsy of the intraocular (vitreous) fluid was negative. As her condition progressed, she required repeated diagnostic surgeries and finally a highly complicated and technical biopsy of the retina before a diagnosis of lymphoma was confirmed. Subsequent chemotherapy and radiotherapy saved her vision and life.

Q: In what ways do you think your expertise can improve your patients’ lives?

Every person’s sight is precious. My expertise in ophthalmology not only helps to restore vision, but also to save vision. Restoration of sight in cataract and refractive surgeries improves the quality of life in all patients with blurry vision. #readmore

This is even more important when my particular expertise can help to preserve vision in sight-threatening complications like retinal detachment, macular hole, severe ocular inflammation, age-related macular degeneration and even diabetic retinopathy, where without timely and expert treatment, patients will lose vision or become blind.
