Department of Ophthalmology (Eye Center)


Patient Care

1. Cornea and Ocular surface diseases

Regarding corneal diseases, Professor Yuichi HORI, who specializes in the treatment of corneal and ocular surface diseases, was appointed as the director of the department in April 2014, providing more specialized medical care than ever before. He launched the corneal transplant system in this hospital in July 2014. Now, our cornea unit has three cornea transplantation surgeons and has dealt with many cases of corneal transplantation including penetrating keratoplasty (PKP), anterior lamellar keratoplasty (ALK), and endothelial keratoplasty (EK). We also have started the ocular surface regenerative surgery for the patients with severe ocular surface diseases such as Stevens-Johnson Syndrome, Ocular Cicatricial Pemphigoid, and chemical/thermal burns.

We also emphasize the treatment of dry eye, Meibomian gland dysfunction, and contact lens discomfort (CLD). We have been investigating to develop the new diagnostic method and therapies for the ocular surface diseases.

2. Vitreoretinal surgery

We treat all kinds of vitreoretinal diseases, such as retinal detachment, diabetic retinopathy, macular hole, anterior retinal membrane, etc. In vitreoretinal surgery, we aim for minimally invasive treatment using a 25-gauge / 27-gauge system. Especially for retinal detachment, we have achieved a high cure rate by selecting vitreous surgery and buckling surgery in consideration of the condition of the retina. We have also obtained good results with laser treatment and vitrectomy for diabetic retinopathy.

3. Macular diseases

We treat macular degeneration caused by aging and myopia, macular edema caused by retinal vein occlusion and diabetic retinopathy, and central serous chorioretinopathy. In particular, age-related macular degeneration is a leading cause of blindness in the elderly. In our department, we perform combined therapy with anti-VEGF drug vitreous injection and photodynamic therapy for age-related macular degeneration, and we have obtained good treatment results.

For macular edema due to diabetic retinopathy and retinal vein occlusion, proactively introduce anti-VEGF drug vitreous injection, and depending on the condition, use local administration of steroids or laser treatment in combination to improve symptoms safely and efficiently.

Also, we have performed the variety of clinical research to find a new mechanism of diseases and a new therapy. One of the major features of our department is the examination of ocular blood flow using the latest equipment "laser speckle flowgraphy (LSFG)" that can measure blood flow in the retina and optic nerve. Immediate measurement of retinal blood flow such as diabetic retinopathy and age-related macular degeneration is applied for diagnosis and treatment.
 Figure: Laser specle flowgraphy. We can observe the blood flow of retina and/or optic nerve in a short time, non-invasively.

4. Pediatric Ophthalmology

Pediatric ophthalmology is a particularly specialized field, with orthoptists specializing in pediatrics engaged in medical care. It is the oldest subspecialty unit in our department. We have achieved a high cure rate in amblyopia treatment and strabismus surgery.

We have treated many cases for retinopathy of prematurity in our department,obtaining good results by performing fundus management and laser treatment. We also perform the latest neonatal ocular blood flow measurement.

Nowadays, especially in Asia, the progression of myopia become a big problem. High myopia has higher risk of glaucoma, retinal detachment, macular degeneration, etc. We have started myopic control therapy for children. There are several choices we perform to prevent the progress of myopia for children, such as orthokeratology, bifocal contact lens, and/or low-dose atropine eye drop.
