Risk factors of pseudophakic retinal detachment

To evaluate the risk factors that might cause retinal detachment [RD] after ECCE and IOL implantation in Egyptian patients 24 eye with pseudophakic RD were analyzed for possible risk factors predispong to RD. Axial lengh 24 /= 25 mm, lattice degeneration, ocular trauma and previous RD in the fellow eye

Conjunctival advancement with or without bleb excision for repair of late-onset bleb leaks following glaucoma filtering surgery

The purpose of this study is to evaluate the safety and efficacy of conjunctival advancement with or without bleb excision for repair of lateonset bleb leaks. Sixteen eyes of sixteen patients were included in this study with failure of conservative treatment. Eight eyes underwent conjunctival advancement over the preexsting bleb [Group I] and eight eyes treated with conjunctival advancement with bleb excision [Group II]. Success was defined as resolution of the bleb leak, intraocular pressure [lOP] less than 21 mm Hg without glaucoma Medication and No appearance of vision-threatening adverse event. Success rate was 75% in group I and 62.5% in group II with a mean [ +/- SD] follow-up 17.2 +/- 7.2 and 15.5 +/- 6.7 months respectively. The mean [MD] prerevision lOP was 4.9 +/- 3.2 [group I] and 5.2 +/- 3.4 mm Hg [group II] and mean [MD] postrevision lOP was 12.6 +/- 4.4 [group I] and 14.4 +/- 5.3 mm Hg [group II]. The difference between prerevision lOP [p = 0.45], postrevision lOP [p = 0.25], and visual acuity changes [p= 0.5] between group I and II were statistically non-significant. Comparison between prerevision and postrevision lOP in group I and II revealed significant elevation of lOP after bleb revision [p= 0.01 and 0.006- respectively]. Conjunctival advancement with bleb preservation [group I] is effective and simpler technique than with bleb excision [group II]. In addition to minimal risk of lOP elevation

Epidemiology of blindness and visual impairment in children of Ismailia governorate

The purpose of this study was to obtain an accurate estimate of the prevalence and causes of blindness and visual impairment in children and to determine the methods of prevention of blindness in Egypt.5765 children aged 9 - 15 years undergone ophthalmic examination included visual acuity [V.A], anterior segment and posterior segment examination. Any causes of blindness and visual impairment were recorded. Monocular blindness was mainly due to amblyopia, while binocular blindness was mainly attributed to glaucoma, corneal opacity, cataract and optic nerve atrophy. Error of refraction, corneal foregin bodies, glaucoma, trachoma, cataract and iridocyclitis were important causes of visual impairment. Programs of visual acuity examination, health education and early treatment of blindness and visual impairment should be performed

Effect of topical antiglaucoma drugs on corneal epithelium wound healing in rabbits

Topical antiglaucoma drugs had been used frequently in treatment of different types of glaucoma. Some of these drugs cause inhibition of corneal epithelial wound healing. So, this study aimed to determine the toxic effect of topical antiglaucoma drugs on corneal epithelium of the rabbit. In the present study, seven antiglaucoma drugs [[1] Timolol maleate 0.5%; [2] Apraclonidine HCI 0.5%; [3] Dipvefrin HCI 0.1%; [4] Betoxolol HCI 0.5% [5] Levobunolol HCI 0.5%, [6] Befunolol HCI 0.5%, and [7] Pilocarpine HCI 2%] in their therapeutic concentrations were applied to the cornea of the rabbit which undergone mechanical removal of the epithelium 8 mm in diameter.The rate of healing of conreal wound in saline treated controls was found significant if compared with antiglaucoma drugs.Drugs 5,6,7 demonstrated more rapid healing than drugs 1, 2, 3, 4. In this study, anti glaucoma drugs appear to have toxic effect on the corneal epithelial wound healing specially drug 2 followed by drugs 1, 3, 4
