Application of optical coherence tomography to predict visual outcome in diabetic macular oedema after intravitreal triamcinolone

To study the predictive role of optical coherence tomography [OCT] in patients with diabetic macular oedema treated with a single dose intravitreal triamcinolone injection as regards the visual outcome. This study included 15 eyes of 15 patients of different ages and sex. Preoperative OCT's were carried out, then after intravitreal single dose injection of triamcinolone postoperative OCT's were performed and both results compared over a period of 1-3 months. Visual improvement was better after intravitreal triamcinolone injection in patients showing thickened inner retinal layers on preinjection OCT [high reflectivity of the inner layers] than in cases with thinned inner retinal layers [low optical reflectivity] although macular thickness decreased significantly after the injection in both groups. It may be that a lower optical reflectivity and hence thinning of the inner retinal layers on preinjection OCT's is attributed to atrophy of these layers thus resulting in failure of visual acuity recovery in these patients. OCT pattern has a considerable role in the predicition of visual outcome in patients with diabetic macular oedema after intravitreal triamcinolone injection

Evaluation of changes in peripapillary nerve fibre layer thickness in glaucoma patients using optical coherence tomography after lowering the intraoccular pressure

To assess, using optical coherence tomography [OCT] changes in the thickness of the peripapillary retinal nerve fibre layer in glaucoma patients after surgical lowering of the intraocular pressure. 10 eyes of 8 glaucoma patients were included in this study planned subscleral trabeculectomy was done in all cases. OCT measurement of the peripapillary nerve fibre layer thickness was carried out before and after IOP reduction by the surgery. 8 eyes out of the 10 had and intraocular pressure reduction of more than 30% [from a mean 30mmHg +/- 2.8 SD to a mean 18 mmHg +/- 3.0 SD]. OCT scans were performed 2-3 weeks before surgical intervention and 3-4 months post-operative to measure the thickness of the peripapillary retinal nerve fibre layer. The study showed significant increase in mean peripapillary nerve fibre layer thickness

Treatment of mild to moderate unilateral congenital ptosis using single suture levator resection

To assess the effectiveness single large suture levator resection in the repair of mild to moderate unilateral congenital ptosis. All patients included in the study were younger than 7 years. They all had unilateral congenital ptosis with fair to good levator function. They all underwent levator resection by a single large suture in the ptotic eyelid. At the end of our study, 80% of patients showed sufficient elevation of the ptotic eyelid with a MRD of >/=4mm. 75% of the patients showed symmetry between the two eyelids with eyelid margins within 1mm of each other. The results of our study suggest that the single large suture levator resection procedure is effective in the treatment of mild to moderate unilateral congenital ptosis

Correlation between intraocular lens design, material and posterior capsular opacification rate

To evaluate and to compare the rate of occurrence and degree of posterior capsular opacification [PCO] after small-incision cataract surgery and implantation of two different Intraocular lens [IOL] materials and designs over 6 months follow-up. Magrabi Eye and Ear Hospital, Jedda, KSA, New Dar Al-Shifa Hospital [NDASH], State of Kuwait, International Eye Hospital, Cairo, Egypt. 80 eyes were included in our study. All eyes underwent st and ardized phacoemulsification technique and were divided into 2 groups; Group [A]: 40 eyes implanted with silicone IOL [PhacoFlex, round edged design, Allergan] and Group [B]: 40 eyes implanted with acrylic IOL [Acrysof, sharp edged design, Alcon]. A st and ardized morphological mapping for evaluation of PCO was done 1, 3, and 6 months postoperatively. Nd:YAG capsulotomy rate was also reported. Acrysof group had lower PCO incidence than silicone group, [20% and 30% respectively]. The Nd: YAG capsulotomy rate was 12.5% in Acrysof group and 22.5% in silicone group. Eyes implanted with acrylic lOLs had lesser PCO incidence and subsequently lesser Nd: YAG capsulotomy incidence than those with silicone IOL
