Background and objective: Ocular posterior segment lesions can affect individuals of both sexes at all ages. Such lesions can lead to serious manifestations such as retinal detachment and retinal hemorrhage, leading to permanent loss of eyesight. This study aimed to determine the association between age and gender and changes in ocular posterior segment based on ultrasonography findings. Methods: This prospective cross-sectional study included 50 patients with blurry vision who had been referred from ophthalmology outpatient clinics to the radiology department of Rizgary Teaching Hospital in Erbil, Kurdistan region in Iraq. Required data were collected using a researcher-designed questionnaire, and the patients were examined using a high resolution 7.5-10 MHz linear array ultrasound transducer. Results: The most frequent complications associated with ocular posterior segment pathologies were old vitreous hemorrhage (72%), posterior vitreous detachment (36%), and retinal detachment (34%). Diabetes and hypertension were the most frequent diseases associated with ocular posterior segment pathology. A significant association was seen between the patients' age with old vitreous hemorrhage (P = 0.003). A significant association was seen between the patients’ medical conditions with old vitreous hemorrhage and retinal detachment. There was no significant correlation between the patients’ gender and the studied ocular posterior segment pathologies. Conclusion: Age has a strong correlation with old vitreous hemorrhage, chronic medical conditions such as diabetes, and hypertension correlated with old vitreous hemorrhage and retinal detachment. Keywords: Ocular ultrasonography; Posterior segment pathology; Blurred vision; Age; Gender.

Purpose: Employ fuzzy logic to auxiliary in identification and diagnosis the gravity of diabetic retinopathy (DR). Methods: A cross-sectional study was performed, being assessed 100 diabetes mellitus patients with DR. The following ultrasound findings were measured employing a semi-quantitative punctuation method: vitreous hemorrhage, posterior vitreous detachment, epiretinal fibrosis, retinal detachment. The fundus photography (FP) aspects evaluated for diagnosis of DR were at least four or more microaneurysms with or without hard or soft exudates, and neovascularization, graded using the Early Treatment of Diabetic Retinopathy Scale. With the combination between ultrasound punctuation and FP aspects through fuzzy logic, a classification for DR has been built. Results: Microaneurysms were the findings which presented the better interaction with the DR severity on ultrasound, while the hard exudates showed the minors estimation errors when compared to soft exudates. A classification for DR was suggested based on the 95% confidence interval of number of microaneurysms: mild group (< 24.6); moderately mild (24.6 - 48.0); moderate (48.1 - 64.5); moderately severe (64.6 - 77.0); severe (77.1 - 92.7); and very severe (> 92.7). Conclusion: By the fuzzy logic, a DR classification was constructed supported on number of microaneurysms measurement with a simple practical application.

Background: Internal Limiting Membrane (ILM) peeling, currently, due to more successful hole closure rate and prevention of postoperative reopening, has been accepted globally but it may leads to other trivial complications like subretinal and retinal hemorrhage, vitreous hemorrhage and retinal edema etc., which may be avoided by using adjuvant instruments, like Finesse flex Loop. The aim of this study was to compare complications after ILM peel, with and without finesse loop. Patients and methods: In this comparative cross-sectional study conducted in Ophthalmology Department of Lahore General Hospital, Lahore from February 2018 to January 2019, the data of thirty (30) patients was compared after taking informed consent through self-made pro-forma. Data analysis was done on SPSS-21. Frequency / percentage table of qualitative variables like retinal hemorrhage, retinal tear, retinal detachment and surface irregularities were designed by using excel-16. Fischer’s exact test was applied to compare complications after ILM peeling with and without using Finesse loop. Confidence interval of 0.95 with α of 0.05 was taken as significant. Results: This study included thirty (30) patients (female: 13; male: 17) with mean age of 56 years and 8 months. Comparison between outcomes of ILM peeling with and without using Finesse™ Flex Loop showed that there is statistically non-significant difference in occurrence of retinal hemorrhage (p=0.245), retinal tear (p=0.224), retinal detachment (p=1.00) and surface irregularities (p=0.39). However, the prevalence of complications like surface irregularities, retinal tear, retinal hemorrhage and retinal detachment with finesse loop were less as compared to without finesse loop. Conclusion: The prevalence of complications during ILM peel with finesse loop in a macular hole surgery, were less than that in ILM peel with ILM forceps alone.

The present study aimed to study the effectiveness of B scan in assessing the posterior segment in patients with ocular trauma, so that further treatment plan can be decided and prognosis can be improved. The study was conducted as a cross-sectional study at tertiary care centre during the study period of 1 year on 42 patients presenting with history of ocular trauma. Patients were subjected to detailed history and ocular examination followed by B scan ultrasonography for ruling out posterior segment pathology. Mean age of 42.7±20.2 years and 45.2% patients belonged to 41 to 60 years of age. About 54.8% cases were females. About 50% cases had one or the other posterior segment finding. Retinal detachment followed by vitreous hemorrhage were the most common findings, observed in 19% and 11.9% cases respectively. Avulsion of optic nerve was the least common finding (2.4%). B scan ultrasonography plays an important role in management of patients with ocular trauma for the detection of hidden posterior segment lesions. B scan must be performed routinely in all the cases of ocular trauma for early diagnosis and appropriate management of each case and to reduce the ocular morbidities.

Background: We study the retinal function measured by macular integrity assessment microperimetry (MAIA) and structural changes assessed by scanning swept source optical coherence tomography (SS-OCT) between healthy individuals and patients undergoing pars plana vitrectomy (PPV) after rhegmatogenous retinal detachment (RRD). Methods: Cross-sectional study. Early Treatment Diabetic Retinopathy Study (ETDRS) grids were measured by SS-OCT and compared with the MAIA parameters. Results: Thirty-eight eyes with RRD (19 macula-on and 19 macula-off) were compared with 113 healthy eyes. The retinal sensitivity and average total threshold were reduced in all sectors in the RRD group; macular integrity index was increased. Macular thicknesses in total retina and ganglion cell layer (GCL)++ protocols were higher in the RRD group in nasal outer (NO) and central (C) sectors and only in C sector for GCL+ protocol. Thicknesses were lower in total retina, GCL++ protocols in the temporal outer (TO) sector and in the GCL+ protocol in NO sector. Best-corrected visual acuity (BCVA) correlated moderately with retinal sensitivity in all sectors and in just several sectors with time between the date of surgery and the test. The central nasal (CN) sector thickness and the average total threshold were higher in the macula-on subgroup. Conclusions: RRD and subsequent surgery results in functional and structural changes, especially in individuals with macular detachment.

Background: Hypertension and diabetes are two chronic medical conditions which require aggressive management. When both diseases coexist with hyperlipidaemia, it poses a greater risk for cardiovascular disease than with either of the diseases alone. Self-management, a pillar of chronic disease management, is unachievable if patients are unaware or inadequately informed about their medical condition. Adequate information about a disease and its management will empower patients to manage their medical conditions better Objective: To assess hyperlipidaemia knowledge and practices among hypertensive/diabetic patients with hyperlipidaemia. Method: This study was conducted in a secondary healthcare facility in Lagos State. A cross-sectional study design was used. Data collection was done using researcher-administered questionnaires. An educational intervention was thereafter carried out. Verbal feedback on impact of intervention was received from all respondents. Frequency distribution and cross tabulations were generated using SPSS version 23.0 at significance level set at p<0.05. The knowledge-related questions were scored and converted to percentages. Scores below 50% were considered poor, while scores of 50 % and above were considered good. Results: The overall knowledge scoring revealed that more than half of the patients had poor knowledge of hyperlipidaemia. A significant association was observed between gender and knowledge of hyperlipidaemia (p<0.05); males having better knowledge. Patients had good practices such as good level of medication adherence and appropriate dietary and lifestyle choices necessary for effective hyperlipidaemia management. Conclusion: This study showed that knowledge of hyperlipidaemia is poor in this patient population, especially among the females though patients emonstrated good hyperlipidaemia practices.

Background: Cleanliness and dirt are a dichotomy to categorize a particular environment especially hospital settings in which cleanliness pave a great linkage to patient satisfaction on quality of care and reduction of infection. Dirt creates negative thought on the quality of services being rendered to patients in the hospital environment. Objectives: To assess the perception of patients and their relatives on the level of cleanliness in radiology department of Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto and to determine which amongst the diagnostic rooms is the cleanest (Computed Tomography (CT) room, Routine X-rays room or contrast exams room (fluoroscopy)). Materials and Method: A descriptive cross-sectional study was conducted, 100 questionnaires were distributed to the respondents of which 66 in Routine xray room, 23 in CT suit and 11 in contrast examination room. Out of the 100 questionnaires nine were not returned and the remaining 91 were analysed. The questionnaire contains fifteen statements in total apart from the socio-demographic component. The count of responses was considered and for each type of response (SA, A, N, D, and SD) the percentage were calculated using statistical package for social sciences (SPSS) version 23.0. Results: Sixty percent of the respondents were patients while 40% were relatives of patients that were critically ill. The modal age range of the respondents was 25-34years, 58% were married, while 48.4% were civil servants. The result of our study shows that the respondents have adequate knowledge on cleanliness with a mean score of 4.3, they perceived radiology department as a clean environment for diagnosis and visitation but need further improvement. According to the findings, CT room was the cleanest (87.0%) followed by contrast examination room 64.0% and routine X-rays room was the least 47.0%. It also revealed that lack of manpower is the cause of inadequate sanitation. Conclusion: Radiology Department in Usmanu Danfodiyo University Teaching Hospital is clean and the CT suit is the cleanest.
