RESUMEN
To evaluate the outcomes and complications of phacoemulsification and posterior chamber intraocular lens implantation [PE+PCIOL] in patients with congenital iris coloboma. In a prospective noncomparative interventional case series, 13 eyes of 9 patients [six female and three male] with congenital iris coloboma and cataract underwent PE+PCIOL using clear corneal incision and in-the-bag foldable hydrophilic acrylic IOL implantation by one surgeon. Best corrected visual acuity [BCVA] and complications were evaluated six months postoperatively. Mean age was 46.5 +/- 5.7 years. BCVA was counting finger in six eyes and between 20/200-20/100 in seven eyes, preoperatively which increased to 20/50-20/20 in 11 eyes, postoperatively [P<0.001]. No serious complications occurred intraoperatively. Two eyes had concomitant ocular pathology causing no improvement in their visual acuity after surgery. Two patients developed postoperative monocular dioplopia. No case of retinal detachment occurred during the follow up period. PE+PCIOL seems to be safe and effective in terms of visual improvement in patients with typical congenital iris coloboma and cataract
RESUMEN
To determine the frequency of otolaryngological disorders in patients with congenital nasolacrimal duct obstruction [CNLDO] as compared to controls. In this case-control study, 80 children with CNLDO [cases] and 80 children without CNLDO [controls] were examined for ophthalmological and otolaryngological dosirders. Data analysis was performed using Pearson Chi-square and Fisher exact tests for frequency values and t-test for mean values. Mean age was 22.7 +/- 14.3 [range 5-72] months in the case group and 23.4 +/- 13.7 [range 9-72] months in controls [P=0.76]. CNLDO was bilateral in 7 [8.75%], left-sided in 23 [28.75%] and right-sided in 50 [62.5%] cases .There were no significant differences between cases and controls in nasal, oral and external ear examinations, however otitis media with effusion [OME] was found in 26.3% of cases vs 10% in controls [P=0.01]. Odds ratio for OME in the CNLDO group was 3.2 [95% confidence interval, 1.32-7.75]. Tympanometry was type A in 71.3%, type B in 22.5%, type C in 5% and unrecordable in 1.3% of cases compared to type A in 88.8% and type B in 11.2% of controls [P=0.01]. The incidence of asymptomatic OME in patients with CNLDO is higher than controls therefore, children with CNLDO may need screening for OME for timely diagnosis and treatment
RESUMEN
To compare the effect of implantation of a single-piece hydrophilic foldable acrylic intraocular lens [IOL] with rectangular optic edge and a single-piece polymethyl methacrylate [PMMA] IOL with rounded optic edges on posterior capsular opacification [PCO]. This randomized clinical trial study comprised 74 eyes with senile cataract in an otherwise normal eye in patients older than 50 years. Patients were randomized to receive hydrophilic foldable acrylic or PMMA IOLs. The operations were performed using standard phacoemulsification by the same surgeon. Patients were followed for at least 9 months. PC0 was graded according to slit lamp examination [retroillumination] and best corrected visual acuity [BCVA]. The PC0 values and BCVA at 6 and 9 months after surgery, capsulorrhexis diameter, and post- operative inflammation were compared between the two groups. From 74 patients enrolled in the study, 56 patients including 28 in each group, had complete follow up and examinations. Mean age was 67.64 +/- 7.71 years. Six months after surgery visually significant PCo occurred in 2 patients [7.1%] in the acrylic group and 7 patients [25%] in the PMMA group. [P=0.00l] At 9 months YAG capsulotomy was performed in one eye [3.6%] in the acrylic group and 3 eyes [10.7%] in the PMMA group.[P=0.61] There was no correlation between PC0 with age [P=O.13] or capsulorrhexis diameter [P= 0.8]. Hydrophilic acrylic IOLs cause less PC0 than PMMA IOLs. However, the results cannot attribute to the IOL material alone as they show the importance of both material and design
