Secondary glaucoma associated with crystalline lens subluxation

Pars plana vitrectomy (PPV) is currently used as an effective method in many posterior segment pathologies. Although the most common indication is retina and vitreous pathologies, PPV is also preferred in some cases associated with lens and glaucoma. In case the crystalline lens or artificial intraocular lens, which is a product of industrial development, falls into the vitreous, it is essential to remove it mostly with the PPV approach. In some types of secondary glaucoma, especially malignant glaucoma, successful results are obtained in terms of visual prognosis and complications with vitreoretinal surgery techniques.

Advantages And Disadvantages

Purpose. is to optimize the tactics of performing anterior capsulorhexis in children with congenital lens subluxation in Marfan syndrome with the use of manual and YAG - laser technique. Material and methods. There were observed 25 patients (34 eyes) aged 4 to 11 years old with lens subluxation: 7 children (10 eyes) with congenital cataract and 18 patients (24 eyes) of the clear crystalline lens in Marfan syndrome. The degree of ectopia was different: 14 eyes - 1 degree, 16 eyes-2 degree and 4 eyes-3 degree of crystal ectopia. Manual circular continuous capsulorexis performed 15 eyes in 12 childrens, YAG-laser capsulectomy-19 eyes in 13 children. Results. Use of YAG - laser equipment allowed to excise planned part of of the anterior capsule without mechanical pressure on not fixed lens. Full of YAG-laser anterior capsulorhexis could not be executed in eyes with 3 degree subluxation of the lens (a significant portion of the anterior capsule is covered with an iris). Manual method allowed to execute anterior capsulorhexis at any degree of subluxation of the lens, but required multiple manipulations on the anterior capsule because of clinical and anatomical features anterior capsule in eyes with subluxation of the lens, which significantly prolonged the time of surgery, increasing the risk of developing exudative and proliferative reactions. YAG - laser anterior capsulotomy (dissection of the anterior capsule by YAG laser) with the completion of capsulotomy with the help of instrumental method increases the quality of the surgery. Conclusion.To perform anterior capsulorhexis in children with lens subluxation 1 and 2 degrees can be applied a manual and YAG-laser methods, each of which has its advantages and disadvantages.

Abstract Purpose: To evaluate the visual and anatomical outcomes of pars plana lensectomy and iris-claw artisan intra-ocular lens (IOL) implantation in the patients with subluxated crystalline lens secondary to Marfan syndrome.Methods: In this retrospective case series, we evaluate the records of all patients with Marfan syndrome and moderate to severe crystalline lens subluxation who underwent pars plana lensectomy/anterior vitrectomy and implantation of iris-claw artisan IOL at referral hospital from September 2015 to October 2019.Results: Twenty-one eyes of fifteen patients (10 males and 5 females) with the mean age of 24.47 ± 19.14 years were included. Mean best-corrected visual acuity was improved from 1.17 ± 0.55 logMAR to 0.64 ± 0.71 logMAR at the final follow-up visit (P <0.001). The mean intraocular pressure did not change significantly (P = 0.971). The final refraction showed a mean sphere of 0.54 ± 2.46 D and a mean cylinder -0.81 ± 1.03 at the mean axis of 57.92 ± 58.33 degrees. One eye developed rhegmatogenous retinal detachment two months after surgery.Conclusion: Pars plana lensectomy and iris-claw artisan IOL implantation seem to be a useful, impressive and safe procedure with a low rate of complications in Marfan patients with moderate to severe crystalline lens subluxation. Visual acuity was significantly improved with the acceptable anatomical and refractive outcomes.
