Patients and methods All the patients included in the study underwent ophthalmologic examination and optic coherence tomography of the macula. The injection of 0.2–0.3 ml (8–12 mg) of triamcinolone was done in the subconjunctival space. We evaluated its efficiency by measuring the best-corrected visual acuity and the central macular thickness at 1, 3, and 6 months. Safety was evaluated by following up the intraocular pressure; the presence or absence of cataract and conjunctival complications at 1, 3, and 6 months; and the glycemic control. Results A total of 44 eyes (36 patients) were included. The overall best-corrected visual acuity and central macular thickness improved after injection. Overall, 67% of diabetic patients required reinjection at the third month. In the cases of inflammatory ME (uveitis and Irvine–Gass), the evolution has remained stable for 6 months after a single injection. No significant variation in intraocular pressure was noted after 1 month (P=0.38), after 3 months (P=0.20), or after 6 months (P=0.13). However, four patients developed ocular hypertension (10 mmHg or more above baseline), which has been well controlled with local monotherapy. Overall, 9.5% of phakic patients developed a cataract at the control of the sixth month. The change in glycated hemoglobin before and after the injection was not significant (P=0.84). Conclusion Subconjunctival triamcinolone acetonide seems to be an interesting and well-tolerated alternative therapy of ME in the short and medium term.","PeriodicalId":31572,"journal":{"name":"Journal of the Egyptian Ophthalmological Society","volume":"114 1","pages":"13 - 20"},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49510440","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}

Purpose This study aimed to evaluate the visual outcomes, topographic features, endothelial cell densities (ECD), and complications of deep anterior lamellar keratoplasty using big-bubble technique (BB-DALK) in different corneal stromal pathologies. Patients and methods This was a prospective, interventional study that included 24 eyes of 24 patients having corneal stromal pathologies, not involving Descemet membrane (DM) and endothelium. The primary outcome measures were the clinical, visual, and topographic outcomes (uncorrected visual acuity, best-corrected visual acuity, K1, and K2) throughout the follow-up period, whereas the secondary outcome measures were the refractive outcomes, central corneal thickness, ECD, and intraoperative and postoperative complications. Results A total of 21 (87.5%) patients underwent uneventful BB-DALK, and three (12.5%) cases were complicated by intraoperative DM microperforation who developed DM detachment and double anterior chamber (AC) postoperatively. One of them resolved spontaneously and the other two cases required intracameral air injection. Uncorrected visual acuity improved from 1.55±0.26 (logarithm of minimum angle of resolution) preoperatively to 0.63±0.2 1 year postoperatively (P<0.001) and best-corrected visual acuity improved from 1.08±0.11 (logarithm of minimum angle of resolution) to 0.30±0.12 (P=0.017). Refractive cylinder improved from −7.79±1.75 to −2.85±2.01 at 12 months of follow-up (P=0.007). Average K reading changed from 60.00±7.77 preoperatively to 43.43±2.98 postoperatively (P<0.001). Total ECD was 2248.08±431.13 by the end of the first year, with a mean of 8.2% endothelial cell loss. Loosening of the sutures occurred in five (20.8%) eyes between third and sixth months postoperatively. Urrets-Zavalia syndrome occurred in one of the two cases who were complicated with postoperative double AC and required intracameral air injection.

Aim The aim of this work is to compare the safety and the efficiency of phacoemulsification using conventional and torsional ultrasound modalities for hard nucleus cataracts. Settings and design This was a prospective randomized interventional study. Patients and methods A total of 30 eyes of 29 patients having hard nuclear cataract (grades IV and V) were divided into two groups. Group A included 15 eyes whose cataract was operated on by conventional phacoemulsification using the Infiniti machine. Group B included 15 eyes whose cataract was operated on by torsional phacoemulsification using the OZil technology of the Infiniti machine. Intraoperative ultrasound time and cumulative dissipated energy were recorded. Postoperative central corneal thickness (CCT) was measured at days 1, 7, and 30, and specular microscopy was done at 1 month. Statistical analysis The collected data were coded, tabulated, and statistically analyzed. Results The mean ultrasound time and cumulative dissipated energy and the amount of irrigating fluid were significantly higher in group A. There was a highly significant decrease in endothelial cell count (ECC) in both groups. ECC was significantly lower in the conventional group than in the torsional group at 1 month postoperatively. CCT in both groups was significantly increased at day 1 and then decreased at 1 week and 1 month but was still significantly higher than the preoperative level. CCT became higher in the conventional group than in the torsional group at all follow-up times, but this was significant only at day 1 and week 1 and not significant at 1 month. Conclusion Both ultrasound modalities can be used in hard nucleus phacoemulsification. However, the torsional ultrasound proved to be safer. The choice between these technologies is of particular importance when operating eyes with low ECC.","PeriodicalId":31572,"journal":{"name":"Journal of the Egyptian Ophthalmological Society","volume":"114 1","pages":"1 - 12"},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47522654","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}

Participants and methods This prospective study included 20 eyes of 10 patients showing type 1 ROP, treated with 0.25 mg ranibizumab intravitreal injection only. Patients were followed for 6 months, where peripheral vascularization and rate of recurrence were assessed through indirect ophthalmoscopy and RetCam imaging. Statistical analysis Data were fed to the computer and analyzed using IBM SPSS software package version 20.0. The tests used were χ2 test, Fisher’s exact test, and Student t test. Results A total of 16 (80%) eyes showed good peripheral vascularization and favorable anatomical outcome. The average timing for temporal zone III retinal vascularization was 15.71±2.09 weeks, with three eyes not reaching zone III after 6 months of injection. One eye showed retinal folding and macular ectopia. Three (15%) eyes showed signs of recurrence, with two eyes showing neovascularization at the initial vascular ridge by the fifth week after intravitreal ranibizumab injection (IVR), and one eye showing the recurrence of thick temporal ridge by the fourth months.

Aim The aim was to evaluate the safety and the effectiveness of fenestration technique of the medial recuts muscle with resection of ipsilateral lateral rectus muscle in patients with sensory esotropia. Design A prospective, noncomparative, single-institution interventional study was conducted. Patients and methods This is a prospective study conducted on 16 children with sensory esotropia. Fenestration of the medial rectus muscle is a novel technique of weakening of the medial rectus by excising a rectangular wide central part extending from the insertion to a point back 5–8 mm depending on the angle of the esotropia leaving superior and inferior longitudinal muscle sleeves with no muscle sutures needed. Postoperative angle was reported at 3 months and at final follow-up. Results The procedure reduced the angle of esotropia from mean preoperative angle of 36.6±9 (20–50) to 5.3±5.9 (0–20) PD. Satisfactory horizontal alignment, defined as postoperative alignment within 8 PD of orthotropia at distance, was achieved in 81.25% of the cases at 3 months of follow-up. There were no overcorrections. The procedure was well tolerated by patients.

Patients and methods This prospective nonrandomized study involved patients with silicone-filled eyes recruited over the period from 2015 to 2018. Data from preoperative clinical examination and SD-OCT imaging and proposed modifications on SOR surgery based on both ways of examinations were recorded and compared. Cohen’s Kappa test was used to study the agreement between the clinical and OCT results. Results A total of 146 eyes of 138 patients were included in the study. Before SOR, clinical examination revealed normal macula in 108 (74%) eyes compared with 62 (42%) by OCT. OCT was able to detect significantly higher macular pathologies than did the clinical examination alone (P<0.0005). The number of eyes with macular edema (ME) and epiretinal membrane detected by OCT was significantly higher than that detected clinically (P<0.0005). There was a weak agreement between the results of clinical and OCT examination regarding ME (weighted K=0.426). Modifications added to the routine SOR based on clinical findings were suggested in 25 (17%) eyes compared with 65 (45%) eyes on adding OCT findings in decision making. Superadded modifications based on SD-OCT alone were significantly more in diabetic than nondiabetic patients regarding management of ME and macular retinal detachment (P=0.003). Conclusion SD-OCT was proved to be a helpful tool for following silicone-filled eyes, especially in diabetic patients. Preoperative OCT findings influenced the surgical plans of the routine SOR, thus aided in managing treatable macular lesions such as epiretinal membrane, ME, macular holes, and macular detachment.","PeriodicalId":31572,"journal":{"name":"Journal of the Egyptian Ophthalmological Society","volume":"113 1","pages":"153 - 159"},"PeriodicalIF":0.2,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47194412","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}
