One of the RCTs reported results for 2 of the population groups as part of a subgroup analysis (people with non-proliferative diabetic retinopathy and people with non-proliferative diabetic retinopathy with diabetic macular oedema). The protocol specified that observational studies would be included for comparisons where RCT evidence was not available. However, for the comparisons where there was no RCT evidence, no observational studies met the inclusion criteria. Therefore, only RCT evidence was included in the review. 70 additional studies were identified in the re-run searches, but none met the inclusion criteria for this review.</p><p>Of the 3 populations identified in the protocol, evidence was available for people with non-proliferative diabetic retinopathy, and people with non-proliferative diabetic retinopathy with diabetic macula oedema.

The committee&#x02019;s discussion and interpretation of the evidence</h4><div id="niceng242er9.s1.1.12.1"><h5>1.1.12.1. The outcomes that matter most</h5><p>Both visual acuity and progression to proliferative diabetic retinopathy or macular oedema were considered important for decision making as these are the outcomes that result in the need for additional treatment and can lead to loss of vision for patients. Adverse events associated with treatment were also considered important. The committee also highlighted the importance of peripheral vision, as impairment of peripheral vision can have significant consequences, especially when it comes to activities like driving. However, no studies included in the review reported on peripheral vision outcomes. The committee wanted to consider quality of life outcomes but this was not reported in any of the studies.</p><p>The committee were also interested in information on success of cataract surgery and rates of additional intervention, but no evidence was reported for these outcomes. However, they did not think these were as important to decision-making as the vision- and progression-related outcomes.</p></div><div id="niceng242er9.s1.1.12.2"><h5>1.1.12.2. The quality of the evidence</h5><p>The evidence for the outcomes ranged from low- to high-quality, with most being moderate quality. All studies were considered fully applicable to the review. Evidence was available for people who only had non-proliferative diabetic retinopathy and people who had non-proliferative diabetic retinopathy with diabetic macular oedema. No evidence was available for people with proliferative diabetic retinopathy. The protocol specified that where no RCT evidence was available for a comparison, observational evidence would be considered instead. However, none of the observational evidence that was available for these comparisons met the inclusion criteria for the review.</p><p>The studies reported on a number of different interventions, and each study only reported a small number of outcomes. This meant that there was limited meta-analysis, with much of the evidence instead being based on single study results. This, and the small sample sizes in most of the studies, made it difficult to draw strong conclusions from the results. The committee expected more studies to report on ocular adverse events, particularly with the use of steroids. They thought that the low numbers of adverse events may be due to the way these were recorded by the studies, rather than a lack of adverse events associated with treatment. In addition, the committee discussed how the studies were not powered to show the benefits of adjuvant treatments. This made it difficult to be certain of the true effect of different interventions.</p><p>Most studies considered interventions during surgery. Only one study compared the effects of delivering an intervention before or after cataract surgery. As a result, the committee could not make any recommendations on the timing of interventions relative to cataract surgery.</p><p>The evidence considered the use of anti-VEGFs and of steroids, but there was no evidence for the use of laser photocoagulation before, during or after cataract surgery. The committee discussed how the lack of evidence for laser photocoagulation before cataract surgery is likely to be because the presence of a cataract generally means that the laser would not be able to target the correct areas of the retina, and so this is not common in clinical practice.</p><p>Given the limited evidence base, the small sample sizes, and the reliance on single studies for some comparisons, the committee decided they could not make recommendations on the most effective intervention for any of the populations. Instead, they decided that the limitations of the existing evidence meant that research recommendations were needed (see <a href="#niceng242er9.appk">Appendix K</a>). This will help to ensure that people with diabetic retinopathy or diabetic macular oedema receive the most effective treatments in future.</p></div><div id="niceng242er9.s1.1.12.3"><h5>1.1.12.3. Imprecision and clinical importance of effects</h5><p>The reliance on single study results for many outcomes and the small number of eyes included in some of the studies resulted in wide confidence intervals which crossed the line of no effect for much of the evidence. This made it difficult for the committee to be certain of the true effect of different interventions. It emphasises the need for more comprehensive studies with larger sample sizes to obtain more precise estimates of treatment effects.</p><p>Most of the evidence could not differentiate between different interventions, but the committee thought that this was partly due to the limited evidence base, supporting the need for the research recommendations. There was evidence that visual acuity improved with anti-VEGFs compared to control for people with non-proliferative retinopathy and for people with non-proliferative retinopathy with diabetic macular oedema. However, the committee highlighted that the difference for people with non-proliferative retinopathy was not clinically meaningful. Although the result for people with non-proliferative retinopathy with macular oedema was clinically meaningful, it was based off the result of a single study with a small sample size, which did not report the dose used for bevacizumab. It was therefore difficult to make any recommendations from this result.</p></div><div id="niceng242er9.s1.1.12.4"><h5>1.1.12.4. Benefits and harms</h5><p>The limited number of studies, small sample sizes and wide confidence intervals made it difficult for the committee to be confident of the benefits and harms of each treatment. There was some evidence that anti-VEGFs improved visual acuity compared to control for people with non-proliferative diabetic retinopathy with macular oedema. However, no information was provided on the other outcomes, including adverse events. This made it difficult to be certain of the effectiveness of anti-VEGFs for this group.</p><p>There was no clear difference in effectiveness between the use of steroids and either control or anti-VEGFs. One study showed that steroids can result in a reduced number of treatments, but this was not accompanied by improvements in visual acuity. The committee also discussed the lack of evidence for adverse events, and the limited number of adverse events when they were reported. The committee thought this was likely to be related to how the studies reported the events, rather than a lack of events, as steroids are commonly associated with a higher rate of adverse events. As a result, the committee did not think they could make recommendations on the use of either anti-VEGFs or steroids for people who have non-proliferative diabetic retinopathy with diabetic macular oedema.</p><p>The committee emphasised that their decision to not make recommendations is not due to a perceived lack of effectiveness of different interventions, but due to the limited amount of evidence. For this reason, they made research recommendations for people with non-proliferative diabetic retinopathy and for people with diabetic macular oedema (see <a href="#niceng242er9.appk">Appendix K</a>). The committee thought these were important research topics, as preventing, or slowing, progression will reduce the number of additional treatments that people may otherwise need if they develop proliferative diabetic retinopathy or have further progression of their macular oedema. It will also reduce the number of people who develop more serious outcomes, such as vision loss, which is a major concern to people who have retinopathy. In addition to benefits to patients, an understanding of the most effective treatments will reduce the resources needed to treat people who have progressed.</p><p>The committee were aware of recommendations about managing complications associated with cataract surgery in the <a href="https://www.nice.org.uk/guidance/ng77/chapter/Recommendations#preventing-and-managing-complications" ref="pagearea=body&amp;targetsite=external&amp;targetcat=link&amp;targettype=uri">NICE cataracts guideline</a> about the use of steroids and NSAIDs to manage complications relating to cystoid macular oedema. These recommendations are related to people who are at increased risk of cystoid macular oedema following cataract surgery, including those with diabetes. The committee thought that this information was relevant to the diabetic retinopathy guideline and were not aware of any major changes to the evidence base since the cataract guideline was published. The population that informed the recommendations in the cataract&#x02019;s guideline included a subgroup specifically for people with diabetic retinopathy, and so the committee decided that this was relevant to the diabetic retinopathy guideline and should be highlighted in the recommendations.</p></div><div id="niceng242er9.s1.1.12.5"><h5>1.1.12.5. Cost-effectiveness and resource use</h5><p>No relevant economic evaluations were identified which addressed the cost-effectiveness of treatments before, during or after cataract surgery for managing non-proliferative diabetic retinopathy, proliferative diabetic retinopathy, and diabetic macular oedema. The committee felt more evidence was required to be able to make recommendations on the effectiveness and cost-effectiveness of treatments before, during and after surgery in people with moderate to severe non-proliferative diabetic retinopathy, proliferative diabetic retinopathy, or diabetic macular oedema. As such, the committee proposed recommendations for future research to ensure no unnecessary resource impact is made without any clinical evidence.</p><p>To ensure people with diabetes who are having cataract surgery are treated correctly, the committee felt it was important the surgeon undertaking the surgery should be aware of their current diabetic eye disease status. The committee did not anticipate this would have any resource impact because it is simply ensuring information is being shared correctly rather than requiring any additional resources for treatment or monitoring.</p><p>The committee discussed that anti-VEGFs should be considered as temporary treatment for people who have proliferative diabetic retinopathy and for whom PRP is not suitable because they need cataract surgery. Whilst there was very limited evidence for this recommendation, the committee did not expect there to be a large resource impact because anti-VEGFs would only be expected to be used for short term treatment such as 1 to 2 injections to prevent progression whilst waiting for cataract treatment. The committee felt that the resources saved by reduced progression whilst waiting for cataract surgery would offset the increase in short term costs associated with anti-VEGF treatments. The committee anticipated that the resource impact would be further managed if either bevacizumab or the cheapest available anti-VEGF which is licensed for the treatment of proliferative diabetic retinopathy such as biosimilars were to be the preferred treatment option, because there was limited evidence for differences in clinical effectiveness between the anti-VEGF treatments.</p></div><div id="niceng242er9.s1.1.12.6"><h5>1.1.12.6. Other factors the committee took into account</h5><p>There was no evidence on the use of different services, such as independent centres, for cataract surgery. The committee discussed how many people are now treated for cataracts in independent centres, rather than by NHS services. They thought it was important to highlight that, in their experience, the use of these centres can lead to complications for some people. This is because these people&#x02019;s current retinopathy status is not always identified before cataract surgery. Without this information, surgery may not always be tailored to a person&#x02019;s eye condition, or they may not be given the most effective post-operative medication or follow-up care. The committee therefore decided to recommend that surgeons who are performing cataract surgery should obtain information about a person&#x02019;s retinopathy status prior to surgery. They noted that this information can be identified from a number of sources, such as the NHS diabetic eye screening programme, the Hospital Eye Services medical retina clinic or by examination of the retina.</p></div></div><div id="niceng242er9.s1.1.13"><h4>1.1.13.
