The presence of a hyper-reflective structure on the ONH was carefully evaluated using a volume scan optical coherence tomography (OCT). RNFL thickness and ellipsoid zone (EZ) width around the macula were also evaluated by OCT. Laser speckle flowgraphy was used to measure the mean blur rate of the entire ONH area, which was subsequently divided into the vessel area (MV) and tissue area (MT).</p><p><strong>Results: </strong>Twenty-eight eyes of 28 patients with RP (55.4 ± 16.23 years of age) were included. The pale ONH was observed in 10 (35%) eyes. Hyper-reflective structures were observed in seven (25%) eyes. No significant correlation was found between the pale ONH and the presence of a hyper-reflective structure (Pearson's chi-squared test, <i>p</i> = .364). The average of the ONH area, MV, and MT was 8.65 ± 3.08 AU, 17.81 ± 7.54 AU, and 6.4 ± 2.66 AU, respectively, which significantly decreased in patients with pallor ONH (all <i>p</i> < .05). The global RNFL thickness was 73.54 ± 18.82 μm. The nasal and superior quadrants and global RNFL thickness in patients with a pale ONH were significantly thinner than in patients without a pale ONH (all <i>p</i> < .05). The global and superior and inferior GCC thickness in patients with a pale ONH were significantly thinner than in patients without a pale ONH(all <i>p</i> < .05).There was no difference in the EZ width between patients with and without a pale ONH (<i>p</i> = .107).</p><p><strong>Conclusion: </strong>We conducted multiple assessments of the ONH in RP patients and investigated its clinical significance.

The potential for hyperopic or myopic shift resulting from the co-implantation of the capsular tension ring and intraocular lens remains unclear. This study aimed to determine the postoperative refractive prediction error and the direction of refractive shift in cataract patients who underwent capsular tension ring co-implantation.</p><p><strong>Methods: </strong>We conducted a systematic review and meta-analysis,searching electronic databases for studies of individuals diagnosed with cataracts receiving surgery with or without capsular tension ring implantation. Systematic searches were performed based on five databases: PubMed, Cochrane Library, Web of Science, Medline, and China National Knowledge Infrastructure. The primary outcome was the mean arithmetic refractive prediction error. Secondary outcomes were mean absolute refractive prediction error and the number of eyes within a certain refractive prediction error range.
