Visual outcome and complications of pars plana vitrectomy for dislocated intraocular lenses

To report factors predicting the visual outcome and complications in eyes that underwent pars plana vitrectomy [PPV] to manage dislocated intraocular lenses [IOLs]. A retrospective chart review was performed. Clinical data recorded from the patient charts include, demographic, preoperative, intraoperative, and postoperative, with emphasis on visual acuity, interval between IOL dislocation and pars plana vitrectomy, surgical method and complications. Patients with follow-up of less than three months were excluded. Ninety-four patients were identified, 63 males and 31 females. Age ranged from 2 to 85years [mean 52.6]. The range of follow-up was 3 to 108 months [mean +/- SD 19.4 +/- 17.4months]. The final visual acuity was 20/50 or better in 52 [55.3%] eyes. Our analysis indicated that visual rehabilitation with IOL was significantly associated with better visual acuity as compared with eyes that were left aphakic [P=0.0092]. There was a trend toward a better visual outcome when PPV was performed within two weeks from the diagnosis of the dislocated IOL which was associated with good visual outcome [20/200 or better] in 85.7% of eyes compared with 78.8% of eyes. Management of IOL by interofixation was associated in [90.0%] of eyes with good vision [20/200 or better] compared to 76.1% eyes that had exchange of IOL through the limbus. Postoperative complications include cystoid macular edema in 9 [9.6%], glaucoma in 9 [9.6%], bullous keratopathy in 8 [8.5%], retinal detachments in 6 [6.4%] eyes, and relapsing uveitis in 2 [2%]. In this series, the final visual outcomes were improved and the rate of postoperative complications were low. Eyes that were pseudophakic had significantly good visual outcome compared with eyes that were left aphakic. To the best of our knowledge, this may be the largest study on dislocated IOL removal by PPV with good visual results compared to other studies

Fireworks injury resulting in visual loss: a case report

Firework displays are often a part of celebrating important occasions throughout the world. Fireworks are hazardous to both the community and individuals, and the damage they cause ranges from fires to personal injury. In one year alone, 8200 victims of firework-related injuries were treated in emergency rooms in the United States. It has been estimated, however, that only 40% of such injuries are reported. The American Academy of Ophthalmology received reports of 700 fireworks-related injuries in a single day on July 4, 1985. The eyes are the body part most often iniured by fireworks, followed by hands and fingers. In this report a bottle rocket, one of the so called "safe and sane" devices, caused permanent visual loss in one eye of a boy spectator. To the best of our knowledge, this is the first report of a firework-related ocular injury from Saudi Arabia

Rhegmatogenous retinal detachment in young adults

Purpose: A retrospective study was conducted to assess the etiological factors for rhegmatogenous retinal detachment [RRD] and the visual and anatomical outcome of treatment in a group of young Saudi adults.Methods The records were retrieved of all patients aged between 14 and 40 years who had been treated by the authors for RRD from October 1991 to October 1994 to at the King Abdul Aziz University Hospital in Riyadh, Saudi Arabia. All patients aged between 14 and 40 years who had attended at least two postoperative follow-up visits were included in the study. The etiology, treatment, and visual and anatomic outcome of treatment were recorded Fellow eye pathology and management were also evaluated. The final study group comprised 74 patients [63 males and 11 females] aged from 14 to4O years [mean, 31.8 +/- 5.4 years]. Twenty-three patients [31.1%] presented with RRD secondary to retinal breaks associated with lattice degeneration; retinal detachment [RD] was bilateral in seven of these patients. All patients were myopic before treatment, ranging from -1.0 to -12.0 diopters [D] [mean -7.4 +/- 3.2 D]. The fellow eye needed prophylactic treatment. Twenty-one patients [28.4%] had trauma-related detachments. RRD due to atrophic holes without other pathology was noted in 13 patients [17.6%]. Refraction ranged from +0.5 to -19.0 D [mean, -90 +/- 7.4 D]. RRD due to horseshoe tears was found in seven patients [9.5%]. Their refraction ranged from -43.5 to -23.0 D [mean -9.9 +/- 8.2 D]. Five patients [6.7%] were found to have RRD secondary to giant breaks. The refraction s between -8.0 to -14.0 D [mean -11.2 +/- 2.04 D]. Two patients [2.7%] had aphakic RRD following surgery for congenital cataract. Another two patients [2.7%] had rhegmatogenous retinal detachment following pars planavitrectomy. Choroidal colohoma was found in one patient [1.3%]. In all groups there was a male predominance. Conclusion Lattice degeneration and trauma were the most important causes of RRD in young Saudi adults. Patients with lattice degeneration-related RRD had the most favorable surgical and functional outcome. RRD is frequently a bilateral disease in all etiologie groups except trauma
