“…Furthermore, the prevalence of visual impairment in the current study is higher than other studies in Nigeria (24.1%) [ 37 ], Tunisia (22.2%) [ 26 ], Cameron (29.7%) [ 29 ], Ghana (18.4%) [ 24 ], Zambia (17.1%) [ 23 ], Turkey (13.5%) [ 20 ], Peru (40.2%) [ 18 ], Jordan (17.7%) [ 19 ], Southern China (10%) [ 31 ], and Sankara Nethralaya (4.1%) [ 17 ]. This discrepancy is most likely due to differences in the case definition, socio-economic, and quality of chronic disease care service.…”

Background Visual impairment is a functional limitation of the eye(s) that results in reduced visual acuity, visual field loss, visual distortion, perceptual difficulties, or any combination of the above. Type 2 diabetes mellitus is one of the common causes of visual impairment. Since there is no study conducted in Ethiopia so far in this regard, the current study aimed to determine the prevalence and predictors of visual impairment among people living with diabetes at Dessie town Hospitals, Northeast Ethiopia. Methods Institution based cross-sectional study was carried out from 15 February to 15 March 2020 using simple random sampling to recruit study participants among type 2 diabetes. Visual impairment was measured using visual acuity test. We used Epi Data 3.1 and SPSS version 22 for data entry and statistical analysis, respectively. Bi-variable binary logistic regression was performed to check independent association of each factor with visual impairment. After selecting candidate variables at p < 0.25, we computed multivariable binary logistic regression to identify statistically associated factors of visual impairment. The degree of association was determined using adjusted odds ratio with 95%CI. In the final model, statistical significance was declared at p < 0.05. Results Three hundred and twenty-two people living with T2DM participated in this study with 97% response rate. The prevalence of visual impairment was 37.58% (95% CI: 32.3, 42.9). Age (AOR: 1.06, 95% CI: 1.02, 1.09, p < or = 0.001), poor regular exercise (AOR = 2.91, 95%CI: 1.47–5.76, p < or = 0.001), duration of DM above 5 years (AOR = 2.42, 95% CI: 1.25–4.73, p < or = 0.01), insulin treatment (AOR = 14.05, 95% CI: 2.72, 72.35, p < or = 0.01), and poor glycemic control (AOR = 2.17, 95% CI: 1.13–4.14, p < 0.05) were statistically associated with visual impairment. Conclusion The prevalence of visual impairment in Dessie town hospitals accounted for more than a third of patients living with T2DM. Visual impairment is associated with increased age, poor regular exercise, longer duration of DM, and insulin treatment. Thus, early detection of VI through screening and regular follow-up is recommended to reduce the risk of VI and vision loss.

“…Diabetes and diabetic retinopathy are known to be in rise in the world, the number of vision-threatening diabetic retinopathy is expected to increase from 37.3 million to 56.3 million, (8,9) therefore, an increase in the frequency of diabetes related blindness is likely to occur. Effective measures should be taken to control the leading causes of blindness and its associated risk factors so as to avoid such morbidity among diabetics.…”

Objectives: To investigate the causes of severe visual impairment among Jordanians with type II diabetes mellitus and its associated systemic factors. . After getting the ethical approval and taking a consent form, all patients with type II diabetes mellitus who attended the medical retina clinic in the ophthalmology department and found to have best corrected visual acuity (BCVA) of less than 6/12 in the best eye were included in the study. The patients were subjected to detailed ophthalmic exam including best corrected visual acuity using Snellen chart, anterior segment exam using slit lamp bio-microscopy, intra-ocular pressure measurement using Golmann applanation tonometry and posterior segment exam using 78 and 90 diopter lens. The patients were divided into two groups; Group A where the best corrected vision in the good eye is 6/60 or worse and Group B where vision in the good eye is less than 6/12 and better than 6/60. The outcome of ocular exam in both groups was recorded and compared and the overall data were analyzed using the Excel.Results: Ninety-three patients aged between 43 and 80 years (mean 63.1± 12) were included in the study, 55% of them were males with a ratio of 1.2: 1. The duration of Diabetes Mellitus (DM) ranged between 5 and 30 years (mean 14.4± 5 years).The hemoglobin A1c (HbA1c) ranged between 6.2% and 12% (mean 8.7± 1.2). Sixty-five patient (70%) had BCVA less than 6/12 and better than 6/60 while 28 patients (30%) had BCVA of 6/60 or less. In Group A, 20 patients (70.4%) had proliferative diabetic retinopathy (PDR) while the remaining patients had non-proliferative diabetic retinopathy (NPDR). On the other hand PDR was found only in 11 patients (16.9%) in Group B, 46 patients (70.8%) in this group had NPDR and 8 patients (12.3%) had no DR. Macular edema was found in 86.2% of patients with severe visual impairment. Hypertension, hyperlipidemia, and renal failure were present in 46%, 19% and 13% of the patients, respectively, and showed statistically significant association with severe visual loss (P value <0.01). Age more than 63 years and duration of DM more than 10 years also showed significant association. Conclusion: legal blindness is frequently found among Jordanian diabetics at king Hussein Medical Centre. The most common ocular finding in patients with severe visual impairment (best corrected visual acuity is 6/60 or less) is macular edema. Hypertension, hyperlipidemia , renal failure, age more than 63 years and duration of DM more than 10 years showed statistically significant association.

“…In addition, diabetes mellitus increases the risk of cataracts, especially at younger ages, and the turbidity of the lens hinders visualization of the patient's retina during funduscopy [5,6]. The presence of cataract was also found to be the most significant risk factor for visual impairment in diabetic patients [7,8]. It is estimated that up to 20% of cataract surgeries are performed in patients with diabetes mellitus [9][10][11].…”

Introduction This study aimed to compare the short-term changes in retinal and choroid thickness in diabetic patients after femtosecond laser-assisted cataract surgery (FLACS) and phacoemulsification (PE) surgery. Methods A total of 47 eyes in the PE group and 44 eyes in the FLACS group were included. All patients underwent measurement of central macular thickness (CMT) and subfoveal choroidal thickness (SFCT) before and after surgery using optical coherence tomography (OCT). Results The effective phaco time (EPT) in the FLACS group was significantly reduced. The BCVA differed significantly between the two groups at 1 week and 1 month after surgery. The CMT in both groups increased at 1 week after the operation. It did not return to the preoperative level until month 12 in the PE group. In the FLACS group, the CMT began to decrease at month 3 and recovered to the preoperative level at month 12. The SFCT of the two groups increased at week 1; it began to decrease at month 6 in the PE group but did not recover to the preoperative level until month 12. The SFCT in the FLACS group recovered to preoperative levels at month 6. In the PE group, baseline CMT values predicted CMT change at week 1 and months 1, 3 and 12 after surgery. In the FLACS group, baseline CMT predicted CMT changes at week 1, month 1 and month 3. In the FLACS group, EPT predicted SFCT change at month 3. Conclusion FLACS is safe and effective in patients with no fundus change or mild diabetic retinopathy. It has advantages in effectively reducing EPT, achieving good vision earlier and promoting faster recovery of the retinal and choroidal thickness. Preoperative CMT is a significant predictor of CMT changes in the early period after FLACS.
