The cohort consists of 20 eyes with ACD < 2.8 mm and 25 eyes with ACD > 3.2 mm. Patients’ demographic variables and their predicted refractive outcomes using the SRK-T, Haigis, Holladay 1, and Holladay 2 IOL formulas were collected. Actual refractive outcomes were obtained from consultations at least one-month postoperatively. RS was calculated from the difference between predicted refraction outcome of IOL formulas and the actual postoperative refraction achieved. \u0000Results: The linear correlations between ACD and RS were not significant (p > 0.05). In the group with ACD < 2.8 mm, the mean refractive surprise using SRK-T, Haigis, Holladay 1, and Holladay 2 formulas were -0.191 ± 0.541, -0.189 ± 0.444, -0.201 ± 0.449, and -0.154 ± 0.489 D, respectively. In the group with ACD > 3.2 mm, the mean refractive surprise using the IOL formulas were -1.364 ± 0.541, -1.420 ± 0.541, 0.027 ± 0.394, and -0.045 ± 0.343 D, respectively.  \u0000Conclusion: The positive linear correlation between ACD and RS was weak.

A systemic health review in combination of the symptoms and clinical picture led to the diagnosis of severe ulcerative blepharitis. Immediate oral antibiotics were started along with topical antibiotic cream. Ulcerative blepharitis can be easily misdiagnosed with sebaceous cell carcinoma. The pathophysiology of ulcerative blepharitis points to synergy between infectious entity and inflammatory aetiology, with either bacterial or fungal microorganisms as the trigger agents. Almost all cases of ulcerative blepharitis should include a dermatological evaluation given there is a strong association between ulcerative blepharitis and atopic dermatitis.","PeriodicalId":39864,"journal":{"name":"Asian Journal of Ophthalmology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69888172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preoperative and postoperative evaluations comprised objective and subjective refraction, best corrected visual acuity (BCVA), slit lamp biomicroscopy, applanation tonometry, and dilated fundus examination. \u0000Results: Fifty-six eyes of 56 patients were analyzed. Mean age was 60.55 ± 17.2 years. The most common indication for IFIOL implantation was surgical aphakia following complicated cataract surgery (n = 33; 58.9%) followed by trauma (n = 10; 17.9%), dropped nucleus/IOL during primary surgery (n = 6; 10.7%), and subluxated/dislocated lens-induced glaucomas (n = 5; 8.9%). BCVA better than or equal to their preoperative BCVA was achieved in 96.43% patients. The surgical aphakia and paediatric/adolescent groups had the best visual results while the dropped nucleus/IOL group and subluxated lens-induced glaucoma groups fared poorly. On the long-term follow-up visit, the most common complication noted was pigment dusting on the corneal endothelium (65.7%). \u0000Conclusion: The long-term results suggest that posterior IFIOL implantation is a safe and effective method for correction of aphakia and can be used for a wide range of indications in eyes without adequate capsule support. It may be considered an easier and faster alternative with minimal manipulation to anterior segment structures in paediatric and post-traumatic aphakic eyes.","PeriodicalId":39864,"journal":{"name":"Asian Journal of Ophthalmology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45675409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IOP was measured by a single trained examiner using rebound tonometer (RBT), Ocular Response Analyzer (ORA), Goldmann applanation tonometer (GAT), dynamic contour tonometer (DCT), and Tono-Pen. Corneal hysteresis (CH) and corneal resistance factor (CRF) were measured using ORA, central corneal thickness (CCT) using ultrasonic pachymeter, and corneal curvature (CR) with manual keratometry. All measurements were done one week prior to surgery and after four weeks and six weeks of the two surgeries, respectively. Only the operated eye was included for analysis. \u0000Results: Twenty-nine eyes of 29 normal subjects who underwent phaco-IOL and 23 eyes of 23 glaucoma subjects who underwent phaco-trab were studied. Increase in CCT [10.2 ± 14.86 microns, p = 0.001], decrease in CH [0.82 ± 1.38 mmHg, p = 0.003] and CRF [0.97 ± 1.0 mmHg, p < 0.001] were found post-phaco-IOL, whereas post-phaco-trab decrease in CCT [16.61 ± 15.22 microns, p < 0.001], CRF [2.28 ± 1.93 mmHg, p < 0.001] with increase in CH [0.95 ± 1.89 mmHg, p = 0.03] were noted. Multiple linear regression analysis showed significant associations for change in CH and CRF with change in IOP and not with CCT and CR postoperatively. \u0000Conclusion: Alterations in CH and CRF were associated with changes in IOP measured postoperatively by different tonometers.

At presentation, her visual acuity was 20/400 in the right eye and hand motions close to face with accurate projection of rays in the left eye. Intraocular pressure was 38 mmHg in the right eye and 48 mmHg in the left eye without any antiglaucoma medications. A slit-lamp examination revealed bilateral circum-corneal conjunctival congestion, corneal edema, and shallow anterior chambers. Both pupils were mid-dilated and non-reactive to light. Gonioscopy showed closed angles in all four quadrants bilaterally. Posterior segment examination revealed normal optic disc with cup-disc-ratio of 0.3 in the right eye, and blurring of disc margin with cup-disc-ratio of 0.3 in the left eye. The patient was started on systemic acetazolamide 250 mg 4 times a day, topical brimonidine 0.2% and timolol 0.5% 2 times a day, and topical dexamethasone 6 times a day in both eyes, following which IOP reduced to 11 and 12 mmHg, respectively, the corneal edema subsided, but the anterior chamber remained shallow. Laser peripheral iridotomy was performed in the right eye and surgical peripheral iridectomy was performed in the left eye. After two weeks, vision improved to 20/30 in both eyes with normal intraocular pressure off antiglaucoma medications. Anterior chambers deepened significantly with clear corneas bilaterally. Gonioscopy at this stage showed essentially open angles with appositional closure in superior and temporal quadrants in the right eye and open angles in all four quadrants in the left eye. Posterior segment evaluation revealed normal optic disc in both eyes. \u0000Conclusions: Bilateral simultaneous acute angle closure is a rare presentation with very few reported secondary causes.

Repeatability of the questionnaire was performed among 30 subjects. A total of 23 questions were there, out of those 6 questions for evaluating awareness, 13 questions for evaluating knowledge, and 4 questions for dertermining the subjects' perception. The questionnaire was distributed among subjects working in both the health science and non-health science fields. From their responses, knowledge, awareness, and perception towards eye donation in working literate population were assessed. A pledge form was also given along with the questionnaire to find the subjects' actual willingness. \u0000Results: Repeatability: The questions in the awareness and knowledge domain showed good repeatability (p > 0.05). More than 50 % of the parameters in the perception domain showed poor repeatability (p < 0.05).  Out of 189 subjects assessed, there were 97 health science and 92 non-health science subjects with total mean age 30 ± 7 years. Good awareness was present between health science (96%) and non-health science (94%). Only 21% of the health science and 11% of the non-health science group had good knowledge about eye donation. Only 25% said ‘yes’ to willingness about eye donation. However, only 3% filled the pledge form. No-one from the non-health science population filled the pledge form. Health science professionals showed more willingness to donate eyes compared to the non-health science group after adjusting for qualification, age ,and gender (odds ratio 2.158, p = 0.031, 95% CI (1.073, 4.341)). Study participants shared willingness to donate eyes and responded against negative perceptions such as \"Family members object to eye donation” (odds: 3.75, p = 0.030, 95% CI (1.14, 12.39)), “Dislike of separating eye from the body” (odds:7.02, p =0.006, 95% CI (1.73, 28.42)), and “Donating an organ is against my religious belief” (odds: 8.51,p = 0.039, 95% CI (1.11, 65.09)). \u0000Conclusion: Our study showed that education qualification and the perception like ‘eye donation is against religious beliefs’ and ‘dislike to separate eye from the body’ showed significant effect on the willingness to donate eyes. More than awareness and knowledge, perception about eye donation had more impact on the willingness to donate eyes. Therefore, more campaigns emphasizing the importance of eye donation need to be conducted to change the perceptions about eye donation rather than improving awareness or knowledge.","PeriodicalId":39864,"journal":{"name":"Asian Journal of Ophthalmology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49426583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
