RESUMO
@#AIM: To study the relationship between optical coherence tomography angiography(OCTA)and eye axis in adolescents.<p>METHODS: Prospective non-randomized clinical study. The clinical data of 33 cases(66 eyes)were collected and analyzed. All the subjects underwent naked vision, diopter, corrected visual acuity, axial measurement and OCT examination. SPSS 19.0 software was used to analyze the relationship between the results of OCTA and the eye axis.<p>RESULTS: The mean axial length was(24.46±1.50)mm, the mean vascular density in macular area was(47.88±2.56)%, and the mean thickness of nerve fiber layer in macular area was(278.61±15.08)μm. The mean perioptic vessel density was(57.79±2.99)%, and the mean capillary density was(53.08±3.49)%. There was a negative correlation between the length of the eye axis and the thickness of the nerve fiber layer in the macular area(<i>P=</i>0.006), but there was no correlation between the axial length and the other results.<p>CONCLUSION: There was a negative correlation between the thickness of nerve fiber layer in macular area and the eye axis, but there was no correlation between the blood vessel density and the eye axis in the detection of fundus OCTA in adolescents.
RESUMO
@#AIM: To evaluate the ocular parameter changes following scleral buckling(SB)for rhegmatogenous retinal detachment(RRD). <p>METHODS: This retrospective, non-randomized case-control study included 46 eyes of 23 patients who underwent SB for RRD. Best corrected visual acuity(BCVA), diopter, intraocular pressure(IOP), anterior chamber depth(ACD), the number of corneal endothelial cells, axial length and the degree of exophthalmos were evaluated in the operated eyes and the follow eyes postoperatively at 3mo. <p>RESULTS: After SB surgery, retina reattachment was achieved without any obvious complications or adverse reactions in all follow-up patients. Among all parameters, the significant decrease in BCVA of 0.15(LogMAR BCVA, <i>P</i>=0.007), in anterior chamber depth(ACD)of 0.29mm(<i>P</i>=0.011)and increase in the degree of exophthalmos of 0.54mm(<i>P</i>=0.047)were observed; the surgery-induced changes for other parameters, including diopter, IOP, counts of endothelial cells and axial length, were not significantly different(<i>P</i>>0.05). <p>CONCLUSION: SB is a good technique for repairing RRD. It brings SB-induced changes in ACD and the degree of exophthalmos.
