Clinical survey over the past 35 years at the clinic for maxillofacial prosthetics Tokyo Medical and Dental University.

Purpose: The purpose of this survey was to examine the overview of maxillofacial prosthetic treatment at our department, in order to ascertain the actual status of patients and discuss future needs.

Methods: Subjects were all patients who visited Clinic for Maxillofacial Prosthetics, Dental Hospital, Tokyo Medical and Dental University (TMDU) in the period from January 1, 1980 to December 31, 2014. Using medical records of the Clinic for Maxillofacial Prosthetics, Dental Hospital, TMDU, patients' data including sex, address, referring institution, and primary condition were analyzed throughout the period.

[Effects of vitrectomy as a treatment for proliferative diabetic retinopathy in young patients].

Purpose: To investigate the effects of vitrectomy as a treatment for the proliferative diabetic retinopathy (PDR) in patients under 40 years old.

Methods: Sixty eyes of 37 patients under 40 years old with PDR who had undergone vitrectomy for the first time in Juntendo University Urayasu Hospital were included in this study. Preoperative condition, operation methods, visual acuity after operation and complications both during or after operation, especially neovascular glaucoma (NVG), were reviewed retrospectively.

Advantages of using newly developed quartz contact lens with slit illumination from operating microscope.

The purpose of this article is to report the characteristics and advantages of using a newly designed quartz contact lens with slit illumination from an operating microscope for intraocular surgery. The new contact lens is made of quartz. The lens is convex-concave and is used in combination with slit illumination from an operating microscope.

Vitreous surgery for diabetic macular edema--its prognosis and correlation between preoperative systemic and ocular conditions and visual outcome.

The effectiveness of vitreous surgery for diabetic macular edema (DME), and the correlation between the preoperative systemic and ocular conditions and the visual outcome following vitrectomy were studied. Visual acuity improved in about 50% of the eyes. Both visual acuity and foveal thickness recovered 12 months after surgery and the improvement of visual acuity occurred later than the recovery of foveal thickness.

Penetrating keratoplasty surgery combined with vitrectomy after failing previous corneal surgery.

Purpose: The preoperative and postoperative factors influencing visual outcome were analyzed in 15 eyes of 15 patients with graft opacity after keratoplasty associated with vitreoretinal disease who underwent combined surgery of fresh corneal retransplantation and vitrectomy.

Materials And Methods: The data obtained consisted of diagnosis, preoperative visual acuity, corneal and vitreoretinal findings at the time of surgery, interval between the first visit and surgery, intraocular pressure before surgery, gonioscopic findings, results of bacterial culture of surgical specimens, surgical procedure for vitrectomy, corneal and vitreous findings after surgery, visual acuity 6 months after surgery, intraocular pressure after surgery, and additional surgical techniques.

Results: The cause of corneal opacity was graft rejection in all patients, who had been treated with high-dose administrations of steroids and cyclosporin.
