ABSTRACT
Sleep is an essential determinant of health and quality of life. This study aimed to evaluate sleep disorders and symptomatic dry eye (DE) occurrence. This study was a cross-sectional survey of 1393 participants in China. The insomnia severity index (ISI) Questionnaire was used to evaluate sleep quality, and the ocular surface disease index (OSDI) questionnaire was used to assess DE symptoms. Subjects were divided into 2 groups based on subjects with and without symptomatic DE. The patients who had DE (10.48â ±â 7.27) had substantially lower ISI scores compared to those without DE (3.57â ±â 5.10) (Pâ =â .003). Furthermore, each ISI item and total ISI score was significantly correlated with OSDI dry eye severity and total OSDI dry eye score. Higher prevalence of insomnia was found in participants with symptomatic DE, and insomnia correlated significantly with DE symptoms. The present results suggest that clinicians and healthcare workers need to remember that DE and insomnia are highly co-existing health issues.

AIM: To assess the long-term efficacy and safety of yttrium-aluminum garnet (YAG) laser vitreolysis for vision degrading myodesopsia (VDM) caused by posterior vitreous detachment (PVD). METHODS: This retrospective study reviewed VDM patients of PVD type undergoing YAG laser vitreolysis. The baseline demographic information, the patterns of floaters, the number of floaters, and the subjective improvement of floater sympotoms (ranging from 0 to 100%) from medical records were collected. Significant improvement was defined as a relief of floater symptoms of ≥50% at the final visit. The long-term efficacy and safety of YAG laser vitreolysis were analyzed. The risk factors linked to significant improvement of floater symptoms were defined using univariate and multivariate logistic regression analyses. RESULTS: The final analysis included 221 patients with VDM. The mean age of patients was 61.08±7.74y, and the mean length of follow-up was 21.38±5.61mo. Totally 57.01% of patients experienced a significant improvement in their floater symptoms after YAG laser therapy, and none of them developed delayed retinal abnormalities such as retinal tears or detachments. Age (OR=1.049, 95%CI=1.007-1.092, P=0.021) was identified as a significant risk factor for significant improvement in VDM. CONCLUSION: YAG laser vitreolysis is an effective and secure treatment for PVD-type VDM, and patients of advanced age are more likely to get favorable outcomes.
ABSTRACT
AIM: To compare the postoperative visual acuity among eyes with proliferative diabetic retinopathy (PDR) of different stages after pars plana vitrectomy (PPV) in type 2 diabetic patients. METHODS: A retrospective study was conducted for PDR eyes undergoing PPV in type 2 diabetic patients. All patients were divided into three groups based on Chinese Ocular Fundus Diseases Society (COFDS) classification for PDR: Group A (primary vitreous hemorrhage), Group B (primary fibrovascular proliferation) and Group C (primary vitreous hemorrhage and/or fibrovascular proliferative combined with retinal detachment). The postoperative visual acuity and the change between postoperative and preoperative visual acuity were compared among three groups. The associated risk factors for postoperative visual acuity were analyzed in the univariate and multiple linear aggression. RESULTS: In total, 195 eyes of 195 patients were collected in this study, including 71 eyes of 71 patients in Group A, 75 eyes of 75 patients in Group B and 49 eyes of 49 patients in Group C. The eyes in Group A got better postoperative best-corrected visual acuity (BCVA) compared to the eyes in Group B and C (0.48±0.48 vs 0.89±0.63, P<0.001; 0.48±0.48 vs 1.04±0.67, P<0.001; respectively). The eyes in Group A got more improvement of BCVA compared to the eyes in Group B and C (1.07±0.70 vs 0.73±0.68, P=0.004; 1.07±0.70 vs 0.77±0.78, P=0.024; respectively). In the multiple linear regression analysis, primary fibro-proliferative type (ß=0.194, 95%CI=0.060-0.447, P=0.01), retinal detachment type (ß=0.244, 95%CI=0.132-0.579, P=0.02), baseline logMAR BCVA (ß=0.192, 95%CI=0.068-0.345, P=0.004), silicone oil tamponade (ß=0.272, 95%CI=0.173-0.528, P<0.001) was positively correlated with postoperative logMAR BCVA. Eyes undergoing phacovitrectomy had better postoperative BCVA (ß=-0.144, 95%CI=-0.389 to -0.027, P=0.025). CONCLUSION: PDR eyes of primary vitreous hemorrhage type usually have better visual acuity prognosis compared to primary fibrovascular proliferation type and retinal detachment type. COFDS classification for PDR may have a high prognostic value for postoperative visual outcome and surgical management indications.
