ABSTRACT
The blue field entopic phenomenon [BFE], which allows the observation of one's own leucocytes flowing in the macular retinal capillaries was used to predict postoperative macular function in 90 consecutive patients undergoing cataract surgery. Ten eyes were excluded because of in cooperation or complications occurred during and after surgery. The test was found positive in 97% of patients had good macular function postoperatively and 83% negative who had poor macular function. The test is noninvasive, inexpensive, easy to perform and provides information on the perifoveal retinal circulation and on macular function. It can also be used to clarify the prognostic value of cataract extraction preoperatively
ABSTRACT
Krypton laser iridectomy was performed on 20 eyes of 14 patients. In eight eyes with closed angle glaucoma the intraocular pressure [IOP] was controlled within normal limits. Eleven eyes with narrow angles maintained a normal intraocular pressure after preventive laser iridectomy. Only in one eye with chronic closed-angle glaucoma the IOP was not controlled after laser iridectomy and the iridocorneal angle remained practically the same as before the procedure. The mean pressure was 28 mm.Hg. applanation before and 18 after the procedure. The iridectomies were performed with the use of Krypton laser power of 200 to 400 mw, exposure time of 0.1 to 0.2 S, and spot size of 50 to 200 u. Blue irides were slightly more resistant to treatment than brown irides. Krypton laser iridectomy by this technique is highly recommended as the procedure of choice for eyes with acute angle-closure glaucoma and for preventive iridectomy in the fellow eyes
