AIM: To identify factors predicting visual improvement post vitrectomy for sequelae of proliferative diabetic retinopathy (PDR).METHODS: This was a retrospective analysis of pars plana vitrectomy indicated for sequelae of PDR from Jan.to Dec.2014 in Hospital Sultanah Bahiyah,Alor Star,Kedah,Malaysia.Data collected included patient demographics,baseline visual acuity (VA) and post-operative logMAR best corrected VA at 1y.Data analysis was performed with IBM SPSS Statistics Version 22.0.RESULTS: A total of 103 patients were included.The mean age was 51.2y.On multivariable analysis,each pre-operative positive deviation of 1 logMAR from a baseline VA of 0 logMAR was associated with a post-operative improvement of 0.859 logMAR (P<0.001).Likewise,an attached macula pre-operatively was associated with a 0.374 (P=0.003) logMAR improvement post vitrectomy.Absence of iris neovascularisation and absence of post-operative complications were associated with a post vitrectomy improvement in logMAR by 1.126 (P=0.001) and 0.377 (P=0.005) respectively.Absence of long-acting intraocular tamponade was associated with a 0.302 (P=0.010) improvement of logMAR post vitrectomy.CONCLUSION: Factors associated with visual improvement after vitrectomy are poor pre-operative VA,an attached macula,absence of iris neovascularisation,absence of post-operative complications and abstaining from use of long-acting intraocular tamponade.A thorough understanding of the factors predicting visual improvement will facilitate decision-making in vitreoretinal surgery.

The important role of non-dental healthcare professionals (HCPs) in promoting oral health is well-accepted and has received increased attention in recent years. However, greater efforts are needed to train them in ensuring better competency in delivering this role. The aim of the present study is to assess oral health and care knowledge among HCPs by further exploring possible challenges faced by them in managing oral health problems, particularly in regard to patients in a public primary healthcare clinic. In the case of the current research, a focus group discussion was carried out with ten HCPs who are directly involved with patients from different units within the health clinics. In particular, the questions developed for the focus group discussion were divided into two parts: (1) knowledge on oral health and its link to general health, and (2) issues and challenges faced by HCPs in handling patients with oral health problems in their daily routine. The session was recorded on a digital audio tape, the responses were then transcribed, followed by the grouping of the scripts which were then qualitatively analysed. The results revealed that majority of the participants appeared to have good knowledge of general and basic oral health; however, only very few of them were aware of the relationship between oral health problems with systemic conditions. Meanwhile, one of the main challenges faced by HCPs in handling patients with oral health problems is their limited knowledge of oral health problems. Specifically, the main challenges refer to the management of medically compromised patient requiring dental treatment as well as the difficulty in changing the mindset of patients regarding oral health issues, especially in terms of seeking dental treatment. In conclusion, it has been clearly observed that HCPs involved in the present study have good knowledge of general health and oral health but limited knowledge related to oral health to systemic health. Furthermore, they tend to face numerous challenges when dealing with patients, especially due to their limited knowledge of oral health facts and drug prescription for oral problems. Therefore, there is an urgent need of additional training for both HCPs and dental teams for the purpose of enabling both parties to provide coordinated and comprehensive service to patients with oral health problems at the primary healthcare clinics.
