Message from Professor Kazuaki Kadonosono

Aiming to provide care that patients will say they were glad to have received

There is a Japanese saying that the eyes tell as much as the lips, meaning that the eyes and gaze reflect most what is in a person’s heart.

Actually, of the five senses, the information obtained through the eyes is the greatest and most striking, and half of the cranial nerves, i.e., the trigeminal nerve, oculomotor nerve, trochlear nerve, abducens nerve, and facial nerve, in addition to the ophthalmic nerve, come together in the eye.

The eyes have always been important, special organs in the human body, and in recent years the many eye diseases accompanying the aging of society and introduction of IT have made people anxious, the same as if for their lives.

The Department of Ophthalmology & Micro-technology is a brand new department with a focus on developing treatments for these sorts of eyes diseases in today’s visual information age.

It places emphasis on adopting treatments that make optimal use of surgical treatments for a variety of disease that impair visual function.
The diseases it targets are macular diseases, including age-related macular degeneration, retinal diseases, such as retinal detachment and diabetic retinopathy, and glaucoma, cataract, trauma, etc.
We are aiming to apply even more refined minimally invasive surgery than in the past to vitreous surgery, and transplantation therapy that utilizes regenerative medicine.

Patients from Kanagawa Prefecture, primarily Yokohama, and, even more widely, from the entire Tokyo metropolitan area, are coming to our hospital and receiving surgical treatment.
Medical and surgical services are primarily provided at Yokohama City University Medical Center, while education is centered at Yokohama City University Graduate School of Medicine.

We in the Department of Ophthalmology & Micro-technology of Yokohama City University Medical Center are continuing to aim to provide medical care that will make patients feel glad to have been treated in our department.
