Purpose
To show posterior surface of iris, ciliary body, lens capsule, lens zonule, ora serrata and pars plana, we have used the method of Miyake-Apple posterior view which is evaluation of eye globe through the glass after frozen eye globe was cut near the equator and placed on the glass. However, this method is complicated for frequent use. In this report, we suggested the new method of Miyake-Apple view using nasal endoscope which was commonly used in oculo-plastic clinic.
Methods
Experimental eye was obtained the patient who received orbital excenteration to remove malignant bulbar conjunctiva and eyelid tumor. To show gross invasion of malignant tumor, we photographed Miyake-Apple view using nasal endoscope (Stryker). First we placed experimental eye in the cornea down and optic nerve up position. 7mm sized sclerotomy was done using number 11 knife near the optic nerve and the endoscope probe was inserted through the sclerotomy. We observed posterior iris, ciliary body, the equator of lens capsule, lens zonule, the relationship of intraocular lens and capsule, ora serrata and pars plana, and each scene saved as photographic or video files.
Results
We can easily observe the posterior iris, ciliary body, the equator of lens capsule, lens zonule, the relationship of intraocular lens and capsule, ora serrata, pars plana, and peripheral retina with high resolution and proper brightness images. The intraocular invasion of malignant tumor was not found in the iris or ciliary body.
Conclusions
Using nasal endoscope, we can conveniently photograph Miyake-Apple view. This method will be very helpful in the clinical laboratory and anatomy field.
