Spontanious luxation of the lens in Marfan syndrome

We report the case of a 22-year-old-man, who presented to the ophthalmic emergencies for decreased visual acuity since 2 days. The clinical examination found visual acuity reduced to counting fingers in the right eye and 3/10 in the left eye. and an anterior lens dislocation in the right eye, while the examination of the left eye after pupillary dilation, revealed lens dislocation in the superonasal direction and absence of zonules from 2 to 5 o’ clock position. The posterior segment examination was normal in both eyes. Otherwise, on general examination we noticed Marfan syndrome characteristic. In our case of the retained diagnosis was Marfan syndrome. The first clinical description was in 1896 by Antoine-Bernard-Jean Marfan [1], which is a rare genetic disease, that touch the conjunctive tissue of many organs, as well the eye that can present many abnormalities as: Ectopia lentis in 50-80%, which is commonly bilateral and many other manifestations also can be seen [2,3].

Utilização do flap de Gundersen para tratamento de disfunção endotelial em equino – relato de caso

Endothelial dysfunction in horses is associated with dystrophy or degeneration of corneal endothelial cells, clinically presented as a diffuse corneal edema unresponsive to conventional treatments. The main causes of such injury are trauma, ulcerative keratitis, recurrent uveitis, anterior lens dislocation and glaucoma. This paper aims to report a case of endothelial dysfunction in a mare, diagnosed with endothelial dysfunction after uveitis, glaucoma and indolent corneal ulcer. For correction, a superficial lamellar keratectomy followed by permanent conjunctival graft, described as a Gundersen flap, was performed. After intensive eye care, he returned to his athletic functions, maintained corneal and visual axis transparency and ocular reflexes.

Traumatic Anterior Dislocation of Ocular Cataract Lens

Case presentation: A 33-year-old male presented to the emergency department following a motor vehicle collision with complaints of right eye pain after hitting his head on the steering wheel. Point-of-care ultrasound (POCUS) revealed retinal detachment and an anterior lens dislocation. Discussion: Lens dislocations following blunt head trauma can often be diagnosed using POCUS. Anterior ocular lens dislocation is a rare but vision-threatening result of head trauma. This case highlights how POCUS can facilitate early detection of ocular pathology, such as lens dislocation, and improves patient outcomes.

Late intraocular lens dislocation. Retrospective study

Purpose. To analyze the frequency, terms and risk factors of late IOL dislocation. Material and methods. A retrospective cohort study was conducted based on archival data of 70 787 cases of the senile cataracts phacoemulsifications performed in 2002–2019 years. Statistical processing of the results and Kaplan–Meier analysis were performed using the SPSS 11.0 program (STATA). Results. 320 patients in the study group were treated for late IOL dislocation at various postoperative periods. The average age of the patients was 76.2±12.5 years at the moment of reconstruction procedure. The periods from the moment of IOL implantation to its dislocation varied from 4 months to 17.58 years, the average term was 6.95±3.67 years. IOL reposition was performed in 272 cases (85.0%) and IOL change – in 48 cases (15.0%). The leading risk factor was pseudoexfoliation syndrome detected in 239 patients (74.7%). Among other factors there was high myopia (72 patients; 22.5%), in 78 cases there were the surgery procedures between cataract surgery and IOL dislocation: glaucoma surgeries – 27 cases (8.4%), vitreal surgeries – 9 cases (2.8%), laser discission of secondary cataract – 42 cases (13.1%). The cumulative 5-, 10-, 15-, and 18- year risk of late IOL dislocation was estimated using Kaplan–Meier analysis. Conclusion. The dynamics of the number of reconstructive operations at late IOL dislocations has a tendency to increase. The average term from the IOL implantation to its dislocation was 6,95±3,67 years. The leading risk factor was pseudoexfoliation syndrome. The cumulative 5-, 10-, 15-, and 18-year risk of late IOL dislocation was 0.2; 0.7; 1.15; and 1.4%, respectively. Key words: intraocular lens, dislocation, phacoemulcification.
