RESUMO

Objective: To compare visual outcomes after cataract surgery using three intraocular lenses (IOL) of different prices but similar properties. Methods: A comparative study with retrospective data of patients operated for phacoemulsification with monofocal IOL implants was carried out at Al-Ibrahim Eye Hospital (AIEH) from April 2021 to Feb 2022. Patients with diabetes, any preoperative ocular morbidity and unclear diagnosis were excluded from the study. Pre and post-operative best corrected visual acuity (BCVA) on 1st day, 7th day and 4-6 weeks were analyzed. IOLs were categorized on the basis of price into economical, standard and premium lenses. To minimize surgical bias, data was further stratified on the basis of surgical expertise. Results: Data of 3237 patients was analyzed. Economical lens (A) was implanted in 2647, standard (B) in 254 and premium (C) in 336 patients. On average BCVA (6/6 to 6/12) was achieved in 88.2% of patients. No significant difference was found at third follow up among BCVA of three IOls operated by senior surgeon, χ2(2) = 3.216, p = 0.20, with median (IQR) is 0.2(0.2) logMAR for Group-A, 0.1(0.2) logMAR for Group-B and 0.2(0.1) logMAR for Group-C. When results of the rest of the surgeons was considered, significant difference was found among BCVA at 3rd follow-up, χ2(2) = 6.661, p = 0.036, with median (IQR) is 0.3(0.2) logMAR for Group-A, 0.2(0.1) logMAR for Group-B and 0.2(0.3) logMAR for Group-C. Conclusion: When surgical factors mainly, surgeon bias is removed, all three types of monofocal IOL had similar visual outcomes.

RESUMO

OBJECTIVE: To evaluate the frequencies of ocular comorbidities among patients with type II diabetes, and the association with multiple systemic factors. METHODS: The retrospective, cross-sectional study was conducted at the Al Ibrahim Eye Hospital, Karachi, and comprised diabetic eye clinic data from April 2014 to February 2022. Demographic, biochemical and ophthalmic findings of the patients were recorded. Ocular findings analysed were best-corrected visual acuity, lens status, corneal changes, optic disc assessment, intraocular pressure and signs of retinopathy and its grading. Data was analysed using SPSS 22. RESULTS: Of the 43,723 subjects, 22,677(51.86%) were males and 21,046(48.13%). The overall mean age was 54.14±10.68 years. There were 21,680(49.58%) patients with diabetes duration 5-10 years. Overall, 33,876(77.5%), had some ocular morbidity, while 9,847(22.5%) had no such complaints. The commonest morbidity was cataract12,607(28.8%), followed by refractive errors 8,508(19.5%), vision-threatening diabetic retinopathy 2,553(5.83%) and suspected glaucoma 1,211(2.76%). Vision 28 threatening diabetic retinopathy and suspected glaucoma represented sustained blindness risk 3,764(8.6%). Increasing levels of low-density lipoprotein were significantly associated with advanced diabetic eye disease and clinically significant macular oedema (p<0.05), while glycated haemoglobin >6.4 was associated significantly with diabetic retinopathy and suspected glaucoma (p<0.05). CONCLUSIONS: Diabetes caused some or the other ocular morbidity that needed intervention. Poor control of biochemical parameters was seen to increase frequency of ocular complications.

RESUMO

INTRODUCTION: Improvement in facial esthetics is a major reason for seeking orthodontic treatment. Soft tissues responsible for esthetics show a variable response to the movement of underlying teeth during orthodontics. METHODS: The purpose of this cross-sectional study was to analyze the response of soft tissues and compare it among groups presenting with different lip thickness and competence. It was carried out on 37 patients with Class I and Class II Division 1 malocclusion who had undergone extractions of maxillary first premolars and had completed their orthodontic treatment. Data were obtained by corresponding lateral cephalometric radiographs taken before and at the end of orthodontic treatment. Association was analyzed with a Pearson correlation test. Differences among groups exhibiting varying competency and lip thickness were tested with an independent sample t test. A P value of ≤0.05 was considered statistically significant. RESULTS: Pearson correlation revealed significant associations among incisor tip retraction with lip base retraction (r = 0.68), lip base thinning (r = 0.41) and vermilion retraction (UV) (r = 0.73). Regression analysis showed a moderate increase in lip length (AB) and thickness at vermilion, which were 0.11 mm and 0.15 mm for each mm of incisor retraction at the tip, whereas stronger effects were observed for UV (0.38 mm) and lip base retraction (0.55 mm). There was significantly more lip base thinning (P = 0.03) and UV (P = 0.04) in the incompetent group compared with the competent group. The AB increased significantly in the sample with thicker lips (P = 0.01). Pearson correlation coefficient showed a strong association of lip retraction at the base and vermilion with the incisor movement at the cervical area, for competent and incompetent lips, and thicker and thinner lips. CONCLUSIONS: Lip retraction at vermilion and lip base thinning was significantly more in patients with incompetent lips, whereas the AB increased significantly more in the group with thicker lips.

RESUMO

OBJECTIVE: To find out the validity of hand-held fundus camera by optometrist using slit lamp 90D biomicroscopy as reference standard for screening of diabetes retinopathy. METHODS: The observational cross-sectional study was conducted at the diabetic clinic of Al-Ibrahim Eye Hospital, Karachi, from August 2020 to May 2021, and comprised diabetics of either gender aged >16 years visiting the outpatient department. Un-dilated fundus photograph of both eyes were taken with non-mydriatic fundus camera. Pupils were then mid-dilated with one drop of tropicamide 1% before capturing retinal images by handheld fundus camera by another optometrist. Both the optometrists identified and recorded the presence and absence of diabetic retinopathy. Subsequently, a retinal specialist examined the fundus with slit lamp 90 D biomicroscopy. Data was analysed using SPSS 23. RESULTS: Of the 500 subjects, 291(58.2%) were males and 209(41.8%) were females. The overall mean age was 54.49±9.16 years (range: 16-83 years). Of the 1000 eyes, fundus was not readable in 130(13%) by hand-held fundus camera, 296(29.6%) eyes by non-mydriatic fundus camera and 76(7.6%) eyes by slit lamp. Sensitivity and specificity of hand-held fundus camera compared to non-mydriatic fundus camera was 89.86% and 80.36%, respectively. In comparison with slit lamp, the sensitivity was 91.71% and specificity was 71.10%. Kappa statistic for diabetic retinopathy detection by hand-held fundus camera versus non-mydriatic fundus camera was 0.705, indicating substantial agreement. Kappa statistic for diabetic retinopathy detection with hand-held fundus camera with semi-dilated pupil was found to be a valid screening tool in the hand of optometrist for preliminary screening of diabetic retinopathy. CONCLUSIONS: Handheld fundus camera with semi-dilated pupil was found to be a valid screening tool in the hand of optometrist for preliminary screening of diabetic retinopathy.

RESUMO

Objective: To find out the most common reasons for refusing orthognathic surgery and to compare the responses along gender lines and in terms of open-ended and closed-ended approaches. METHODS: The cross-sectional retrospective study was conducted from August to December 2020 at the Orthodontics Department of Bahria University Medical and Dental College, Karachi, Pakistan, and comprised of patients who were planned for but refused orthognathic surgical treatment between January 2018 and July 2020. Data was collected through telephone-based interviews to record reasons of avoiding orthognathic surgery. The data-collection tool had both open-ended and closed-ended questions. Data was analysed using SPSS 23. RESULTS: Of the 60 patients, 42(70%) were females and 18(30%) were males with a mean age range of 23.25±2.19years. Overall, 19(31.7%) patients avoided surgery due to additional expense, while post-operative pain was cited as a reason by 35(58.3%) patients. Males were 9 times more concerned about their dental alignment compared to females (p=0.005). Fear of tooth injury (p<0.0001) and intra-operation and post-operation bleeding (p<0.0001) were found twice in males than females. Conclusion: The most common reasons for refusal to have orthognathic surgery were increased cost and post-operative pain. Males were more concerned about dental alignment and had higher fear of post-surgical tooth injury and intra- and post-operative bleeding compared to the females.

RESUMO

OBJECTIVES: To observe and analyze the visual outcomes of cataract surgery of ten years at a tertiary eye care hospital, Karachi. METHODS: An observational study with retrospective data search was conducted in Al Ibrahim Eye Hospital (AIEH), Karachi. Data of all adults (above 16 years) who underwent cataract surgery from 2010-2019 was retrieved from HIMS. Presence of opacity in the lens was labelled as cataract. Surgery was advised when patient's BCVA was found to be ≤ 6/18. Visual assessments of the patients were done on day 01, one week and six weeks postoperatively. Postoperatively, 6/6 - 6/12 was considered as good, 6/18 as mild visual impairment, < 6/18 to 6/60 as moderate visual impairment and < 6/60 as severe visual impairment. RESULTS: A total of 1,027,840 patients visited AIEH with different eye diseases. Among 1027840 individuals, cataract was identified in 88443 (8.6%). Surgery was advised to 58371 and performed in 38616. Records of operated cases (38616) were retrieved. Mean age of patients was 54.96±14.22 years. There were 20578 (53.29%) males and 18038 (46.71%) females who underwent surgery . At the end of sixth week, 3561 (18.4%), patients were found to have "good vision", 12242 (63.43%) had mild visual impairment, 2676 (13.86%) had moderate visual impairment and 822 (4.26%) had severe visual impairment. Corneal Complications was the commonest cause (33.56%) at sixth week. CONCLUSIONS: The institution achieved WHO recommended criteria of "good visual outcome" (6/6 to 6/18) of 81.83% which is near to recommended ≥ 90% and severe visual impairment of 4.26%.

RESUMO

OBJECTIVE: To report the results of implementation of two-pronged system for strengthening of referral and receiving end of referral chain for people with Type-2 diabetes mellitus (T2DM) at a tertiary eye care hospital in Karachi. METHODS: This observational, cross sectional study was conducted from the data collected in "Strengthening Pakistan's response to Diabetic Retinopathy" project. Peripheral referral was improved through community awareness camps (n=48), refreshing knowledge of primary healthcare professionals (PHCP) and conducting retinopathy screening camps (n=85) in the community. T2DM patients with best corrected visual acuity (BCVA) <6/18 or had retinopathy sign on screening were referred to tertiary center. The receiving end of the referral was improved by establishing "one window facility" at tertiary eye care center. Facility consisted of eight stations starting from registration, visual assessment, fundus photographs, consultation with ophthalmologist, anthropometry measurement, consultation with diabetologist to finally meeting with diabetes educator. At every station, patient's information was directly entered in HIMS software. RESULTS: A total of 50,595 patients attended tertiary center over six years. Among all 34685 (68.5%) were new registration and 15910 (31.4%) were follow ups. During first year (2014-15) out of total registered individuals with DM, newly registered were 4414 (89.5%) and 518 (10.5%) were follow-ups. In the final year (2019-20) new cases registered reached to 62% (n= 7916) with 38% (n=4852) follow-ups. Patients referred by PHCP increased from 6.5% in 2014-15 to 43.7% in 2019-20. An increased uptake of all treatment modalities for retinopathy like laser (increased by 16.76%), intra-vitreal injections (by 14.72%) and vitrectomy (by 51.47%) were also observed. CONCLUSION: Implementation of two prong system resulted in improved service uptake, better referral system, enhanced follow-ups and increased intervention uptake.

RESUMO

OBJECTIVES: The objectives were to evaluate the intensity of pain perceived 24 hours following insertion of fixed orthodontic appliance components i-e separators, bands and brackets. METHODS: This cross-sectional study conducted at a Dental College in Karachi (July 2017-March 2018) investigated the amount of pain perceived during different stages of fixed orthodontic treatment. The inclusion criteria were healthy individuals without systemic disease, age 13-26 years, fixed orthodontic treatment candidates having healthy permanent first molars. The exclusion criteria were missing permanent first molars, patients requiring brass wire separators instead of elastomeric separators and molar tubes instead of bands, ongoing or previous periodontal disease and syndromic patients. Pain intensity was assessed in ninety eight patients using a Numeric Rating scale (NRS) at baseline (T0) before insertion, and 24 hours after insertion (T1) of a component. This procedure was repeated six times, twice each for separators, bands and brackets. Scoring was done on the NRS from 0 to 10 where 0 indicated no pain and 10 indicated worst pain possible. RESULTS: A significant difference in perceived pain was found between baseline and after 24 hours of placement of all components (P-value 0.000). Odds ratio indicated that males were at a greater risk to feel pain than females at baseline and after 24 hours of insertion of all components. Mann-Whitney U test showed that the most painful components at baseline were bands (Mean value=0.56) and after 24 hours were brackets (Mean value 6.25). CONCLUSIONS: Significant increase in pain was noted 24 hours after insertion of separators, bands and brackets. The most painful components were bands at baseline and brackets after 24 hours of insertion. There were no significant variations in pain perception based on age. However, males perceived higher pain than females both at baseline and after 24 hours.

RESUMO

OBJECTIVE: To compare the neck length, relative neck length and height between patients with cervical spondylosis and healthy subjects. METHODS: This case control study was conducted at Patel hospital, Karachi after the ethical approval of Bahria University Medical and Dental College (BUMDC) and Patel hospital from September 2018 - February 2019. It enrolled eighty eight cases of cervical spondylosis and eighty eight healthy subjects. Radiographs were taken in the lateral view and neck length was measured as the distance from external occipital protuberance to seventh cervical vertebra spinous process. Then relative neck length was measured by dividing the neck length with height and multiplying it by 100. The Kellgren Lawrence grade scale was used to assess the severity of cervical spondylosis. RESULTS: A total of 176 participants were analyzed. It was found that the height remains the significant determinant. The comparison of cases with control group was done using independent T-test which showed that the cases were significantly shorter than controls with a p-value < 0.05. The other variables such as neck length, and relative neck length were insignificant. CONCLUSION: Short height can be considered as a risk factor for cervical spondylosis. Short-statured individuals should be counseled to adopt measures for the prevention of cervical spondylosis.

RESUMO

OBJECTIVE: To evaluate the correlation between clinical hyperandrogenism-hirsutism assessed by modified Ferriman-Gallwey (F-G) score, anthropometric, metabolic and endocrine parameters among PCOS infertile women. METHODS: This observational study after approval of FRC & ERC of BUMDC was conducted from September 2018-March 2019. It included seventy women aged 20-40 years who presented in infertility clinic of a local Hospital in Karachi. After written informed consent participants were enrolled as per the inclusion criteria of the study and evaluated for cyclical pattern (oligomenorrhoea, amenorrhoea, polymenorrhea), physical (weight, height, BMI), anthropometric, (waist circumference, hip circumference, waist to hip ratio, hirsutism), metabolic (carbohydrate, lipid & protein) and endocrine parameters (serum FSH, LH, LH/FSH ratio, serum testosterone, prolactin and progesterone level). Hirsutism was assessed by visual method through modified F-G score and Pearson correlation was determined between hirsutism and other study parameters. RESULTS: A positive Pearson correlation is found between hirsutism and body weight, BMI, waist and hip circumference, waist to hip ratio (WHR), very low density lipoprotein, cholesterol, triglycerides and testosterone levels. CONCLUSION: Hirsutism has correlation with anthropometric, metabolic and hyperandrgenic disorders in PCOS infertile women as assessed by modified F-G score.

RESUMO

OBJECTIVE: To determine the diagnostic accuracy of non-mydriatic fundus camera for the detection of diabetic retinopathy. METHODS: The cross-sectional study was conducted at Al Ibrahim Eye Hospital, Karachi, from January to May 2015, and comprised patients with type 2 diabetes who were screened for diabetic retinopathy. Single 45° fundus image focussed at macula was obtained and labelled using non-mydriatic fundus camera by a trained optometrist. Photos were labelled as positive (diabetic retinopathy present), negative (no diabetic retinopathy) or unreadable. The pupil was then dilated and fundi were examined by ophthalmologist with slit-lamp and fundus lens. Results of fundus examination were labelled as positive, negative or invisible/indecisive. Results of ophthalmologist were taken as the standard reference to evaluate sensitivity and speci?city for detecting diabetic retinopathy with non-mydriatic fundus camera. SPSS 20 was used for data analysis. RESULTS: Total eyes screened numbered 2970 related to 1485 patients. Diabetic retinopathy was found in 646(21.8%) eyes, 485(20.9%) photographs were unreadable and 1839(57.3%) were normal. Ophthalmologist on slit lamp bio-microscopy labelled 736(25%) eyes as positive for diabetes retinopathy, 335(15%) as indecisive and 1899(60%) as normal. The sensitivity of non-mydriatic fundus camera was 400/556 (72%) while specificity was 1548/1794 (86.3%). Positive predictive value and negative predictive value were 400/646 (62%) and 1548/1704 (90%) respectively. The level of agreement was moderate (k=0.0551) for optometrist compared to ophthalmologist. False positive diagnosis by optometrist numbered 78/1839 (4.24%) and false negative was 123/646(19%). CONCLUSIONS: Non-mydriatic fundus camera was found to be a reliable screening tool for detecting and referral diabetic retinopathy cases to ophthalmologist for further evaluation and management.

RESUMO

OBJECTIVE: To determine the frequency of an increase in intraocular pressure (IOP) after intravitreal triamcinolone acetonide (IVTA) in diabetic versus non-diabetic patients with various chorio-retinal disorders. METHODS: This prospective, interventional comparative case series was conducted at Isra Postgraduate Institute of Ophthalmology, Al-Ibrahim Eye Hospital, Karachi from May 2012 to April 2014. Two hundred thirty seven eyes of 180 patients were enrolled with 90 patients each in diabetic and non-diabetic group, requiring IVTA. IVTA 4mg/0.1ml was injected and IOP was measured at one week, one month, three months and six months in both groups of patients. RESULTS: In diabetic group, 43 patients were male (47.8%) and 47 were female (52.2%), while in non-diabetic group, 56 (62.2%) patients were male and 34 (37.8%) were female. Mean age of patients in diabetic group was 52.21 ± 9.6 years and in non-diabetic group was 51.13 ± 10.75 years. The mean preoperative IOP was 13.6 ± 2.8 mmHg and 14.1 ± 2.4 mmHg in diabetic and non-diabetic group respectively. In diabetic group, mean (±SD) IOP was 16.4 ±4.9 mmHg, 14.6 ±3.6 mmHg, 17.6 ± 9.7 mmHg and 15.5 ± 7.09 mmHg at one week, one month, three months and 6 months post injection. While in non-diabetic cases, mean (±SD) IOP was 14.8 ± 3.33 mmHg, 15.9 ± 4.2 mmHg, 15.5 ± 4.2 mmHg and 14.1 ± 3.2 mmHg at one week, one month, three months and 6 months follow up. The raised IOP was observed in 117 eyes (49%) in both groups of patients, with 78 eyes (65%) in diabetic group and 39 eyes (33%) in non-diabetic group. CONCLUSIONS: After IVTA, an IOP rise was observed more in diabetics than non-diabetic patients.

RESUMO

OBJECTIVES: Primary aim was to review the literature on the prevalence of diabetic retinopathy (DR) and Vision threatening diabetic retinopathy (VTDR) in Pakistan. METHODS: A search of the bibliographic databases (Medline, Pub med, and Google scholar) was conducted from 1990 to March 2017. Articles about prevalence of DR and VTDR in Pakistan were retrieved and scrutinized. The studies satisfying the inclusion/exclusion criteria were considered for detail review. RESULTS: Forty one articles on prevalence of DR were traced out. Exclusion and inclusion criteria were met in 29 studies. In selected studies (29), pooled Prevalence of DR was found to be 28.78% with a variation of 10.6% to 91.3%. Out of 29 studies, DR was classified in 19 studies. Pooled Prevalence of VTDR in these 19 studies was found to be 28.2% (variation of 4% to 46.3%) of patient with retinopathy and 8.6% of all diabetics. CONCLUSION: A great variation in the values of DR and VTDR was observed in this study. Researchers suggest a community based study with uniform methodology to find out a comparable value of prevalence of DR and VTDR in all provinces of Pakistan.

RESUMO

OBJECTIVE: To determine the frequency and the risk factors of hepatitis C virus in pregnant women at Al-Tibri Medical College & Hospital in Gadap Town Karachi. METHODS: This was a descriptive cross sectional study conducted at Obstetrics & Gynecology OPD of Al-Tibri Medical College & Hospital, Isra University Karachi Campus from 10th June to 10th September 2016. A total of 400 pregnant women of 16-45 years of age, who came in outpatient department for antenatal checkup were selected for the study. The diagnosed cases of Hepatitis C were excluded from the study. Detailed history including age, parity, risk factor like history of transfusion, previous surgeries, vaginal deliveries was taken and relevant examination was performed. Patients on routine antenatal investigation if found to have Anti HCV positive on Immunochromatography Test (ICT) method were further confirmed by Elisa. A well designed proforma was used for data collection. RESULTS: During the period of 3 months 400 women in antenatal clinic were tested for hepatitis C, out of which 27 (6.6%) were positive for HCV antibodies. The age of the women included ranges from 16-45 years. Thirteen (7.9%) pregnant women having HCV +ve antibodies fell in 26-30 years of age group. From 27 HCV +ve patients, 19 (70.3%) were multigravida & 8 (29.6%) were primigravida. Majority of the patients (77%) had history of injections. CONCLUSION: There is high prevalence of Hepatitis C infection among pregnant female in our setup. The possible risk factors are injection, blood transfusion and surgery.

RESUMO

OBJECTIVE: To compare the visual outcomes of phacoemulsification surgery with intraocular lens (IOL) in persons with and without diabetes at end of follow-up. METHODS: This was a comparative, cross sectional, observational study with Non-probability, purposive sampling. After approval from "Research Ethical Committee of Isra Post-graduate Institute of Ophthalmology Karachi, 92 patients with cataract in one eye were selected. Patients were divided into two groups. Group A consisted of 48 diabetics and group B consisted of 44 non- diabetics with or without diabetes in the age group ≥ 30 years were included. Patients with small Pupil, Pseudo exfoliation Syndrome, Diabetic Retinopathy, and positive history of Uveitis, Glaucoma, and Macular Degeneration were excluded. Data analysis was performed by SPSS Version 20.0. RESULTS: Best Corrected Visual Acuity (BCVA) in diabetic patients improved from 0.813 ± 0.181 Log MAR pre operatively to 0.183 ± 0.143 after the period of six months post-operatively. Corresponding results in non-diabetics were 0.66 ± 0.31 and 0.08 ± 0.092 Log Mar (P value = 0.001). If WHO criteria was considered, 87.5% diabetics and 92% non-diabetics achieved normal vision (Log Mar 0 to 0.5; ≥ 6/12,) on the first post-operative day. Remaining 12.5% diabetics and 8% non-diabetics achieved moderate vision (0.6 to 1 Log MAR) on first post-operative day improving to normal vision within a week. CONCLUSION: Visual outcomes in diabetics after phacoemulsification with intra ocular lens implant is almost as good as that in non-diabetic patient if the diabetics have no retinopathy and have good glycemic control.

RESUMO

OBJECTIVE: To know the outcomes of cystoid macular oedema after phacoemulsification in patients with and without type 2 diabetes mellitus using optical coherence tomography. METHODS: This non-concurrent, clinical, prospective study was carried out at Al-Ibrahim Eye Hospital, Karachi, from January to August 2015. After phacoemulsification with injectable posterior chamber intraocular lens implantation, eyes of patients were analysed. The patients were divided into diabetic and non-diabetic groups visual acuity, optical coherence tomography and dilated fundus examination were performed preoperatively (baseline) and post-operative 1st week and 6th week. SPSS 20 was used for data analysis. RESULTS: Of the 100 subjects, there were 50(50%) each in diabetic and non-diabetic group. Subsequently, 14(14%) patients were lost to follow-up, and 86 eyes of 86(86%) patients were analysed. Of them, 37(43%) were male and 49(57%) were female. The mean age of participants was 52.21±7.43 years (range: 38-62years). The non-diabetic group had 41(47.7%) patients and the diabetic group had 45(52.3%). There was no clinically significant cystoid macular oedema in either group. Central foveal thickness > 43.94 µm was observed in 1(2.5%) eye in the non-diabetic group and in none in the diabetic group at 1st post-operative week. At the 6th post-operative week, none of eyes in the non-diabetic group and 2(4.44%) eyes of the diabetic group showed macular oedema. There was no statistically significant difference in mean foveal volume between both groups at 1st week (p=0.896) and 6th week (p=0.230). CONCLUSIONS: Cystoid macular oedema after phacoemulsification was equally present in both diabetics and non-diabetics without any retinopathy.

RESUMO

OBJECTIVE: To determine the visual outcome of laser treatment in clinically significant macular edema. METHODS: This interventional and qausi experimental study was carried out at Diabetic Association of Pakistan (DAP) during January 2011 and December 2012. Approval was taken from Research Ethical Committee of Isra Postgraduate Institute of Ophthalmology. Records of 925 eyes of 464 patients with "Clinical Significant macular edema" (CSME), treated with laser photocoagulation were analyzed. Best-corrected visual acuity (BCVA) at the time of presentation and at the last follow up, minimum of one year and maximum of 45 months was recorded and compared. SPSS version 20.0 was used to analyze the data. RESULTS: Diabetic retinopathy was found in 20.3% (1777) of 8742 diabetic attending DAP Hospital" amongst whom 39.6% (705) had Sight threatening diabetic retinopathy. Laser was advised in 96.4% (680) individuals, accepted by 70.5% (480) individuals. Amongst 960 eyes of 480 patients who accepted laser, 925 eyes had clinically significant macular edema and 35 eyes had PDR who are not included in this study. Amongst 925 eyes with CSME, Grid laser was done in 913 eyes (99%) and focal laser was done in 12 eyes (1%). After a follow up of 12 to 45 months, it was found that best corrected visual acuity had declined in 2.4% (22) eyes, stabilized in 67% (619) eyes and improved in 30.7% (284) eyes. One line improvement on Snellen's chart was fond in 21.3% (197) eyes, 2 lines in 8% (74) eyes, 3 lines in 1.2% (12) eyes and 4 lines in one (0.1%) eye with p-value of 0.000. CONCLUSION: Laser therapy is an effective treatment in stabilizing/improving the vision in diabetic macular edema particularly at those centers where only Argon Laser is available and OCF, FFA facilities do not exist.

RESUMO

OBJECTIVE: To determine the frequency and types of age-related cataract in type 2 diabetic patients compared to non-diabetics. METHODS: This comparative, cross-sectional study was carried out at Al-Ibrahim Eye Hospital, Karachi, from July 2014 to June 2015, and comprised both diabetics and non-diabetics. All patients were selected from the out-patient department and had their full ocular examination done, including retinal screening of diabetic patients with non-mydriatic fundus camera. The criterion for diagnosis of cataract was sufficiently advanced lens opacity that caused impaired vision/un-gradable images. Cataract was classified on a morphological basis into cortical, nuclear, posterior sub-capsular and mixed types. RESULTS: Of the 49,384 patients, 4,556(9.2%) were diabetics and 44,828(90.8%) were non-diabetics. Among the diabetics, cataract was found in 1,956(42.9%) compared to 7,050(15.7%) in non-diabetics. Adjusted odds ratio (95% confidence interval) between the two groups was 4.40 (range: 4.11-4.71) (p<0.001). Male-to-female adjusted odds ratio (95% confidence interval) was 2.05 (range: 1.95-2.15) (p<0.001). Nuclear sclerosis was the commonest type in 2,123(46.6%) cataract cases in diabetics whereas posterior sub-capsular cataract was the commonest type in 14,480(32.3%) cases among the non-diabetics. CONCLUSIONS: Cataract was four times more common in diabetics and twice more frequent in men. Nuclear sclerosis was the commonest type of cataract in diabetic patients.

RESUMO

OBJECTIVE: To determine the acceptance of retinal screening, Laser uptake and subsequent follow-up in diabetic patients attending the Diabetes Centre of Diabetic Association of Pakistan (DAP), Karachi. STUDY DESIGN: Observational case series. PLACE AND DURATION OF STUDY: Diabetic Centre of Diabetic Association of Pakistan (DAP), Karachi, from January 2011 to December 2012. METHODOLOGY: All the diabetic patients were screened for Diabetic Retinopathy (DR) with non-Mydriatic Fundus Camera (NMFC). Patients with DR were examined by the ophthalmologist using fundus lens and slit lamp. DR was graded for severity on the basis of modified Airlie House Classification. Patients with Sight Threatening Diabetic Retinopathy (STDR) were advised Laser treatment. Each patient was followed-up for at least 6 months. The records of patients recommended Laser were retrieved, and called for re-examination. RESULTS: Retinal screening was accepted by all of the 8368 registered diabetics attending DAP Centre. On fundus photography, 21.2% (1777) individuals were found to have DR. Seven hundred and five (39.5%) patients were found to have STDR. Laser was advised to 96.4% (680) of STDR patients; amongst whom 70.5% (480) accepted Laser treatment. Out of 480 patients who had Laser treatment, 21.2% (107) turned out for follow-up after 6 months. CONCLUSION: Acceptance of retinal screening and Laser application was good; but follow-up was suboptional.
