RÉSUMÉ
We herein describe the kissing MVR technique in cases of microspherophakia for safe and effective endocapsular lens aspiration. Microspherophakia is associated with abnormally lax and broken zonules, which pose a great challenge to the operating surgeon, especially while creating the openings in the capsular bag. In this novel technique, simultaneous use of two 23 G MVR blades reduces the above problem associated with the severely mobile lens. Here, one MVR blade stabilizes the capsular bag and, at the same time, provides counter-traction for the opposite MVR blade while puncturing the capsular bag. Furthermore, the creation of openings in the lens at the equator or just posterior to it is beneficial as the capsule is relatively thicker and stronger at this location. This also minimizes the risk of premature extension to the anterior or posterior capsule, thereby avoiding complications like dropped lens matter, vitreous prolapse, and vitreous traction.
RÉSUMÉ
A lady who underwent lensectomy for microspherophakia and pars plana vitrectomy for retinal detachment in her left eye developed recurrent filtering blebs at the site of sclerotomies. Filtering blebs were managed by suturing the sclerotomies. Targeted gene sequencing identified a variant of ASPH gene (p.Arg688Gln) which is not known to be associated with Traboulsi syndrome. But considering the paucity of cases with genetic analysis, it would be possible that p.Arg688Gln is a pathogenic variant. This is the first case report of Traboulsi syndrome due to an ASPH variant not reported earlier that can lead to recurrent filtering blebs.

Purpose: To report the outcomes of trabeculectomy in eyes with glaucoma in microspherophakia. Materials and Methods: In a retrospective non-comparative case series, we analyzed 29 eyes of 18 patients with glaucoma in microspherophakia, who underwent primary trabeculectomy between 1998 and 2012. Success was defi ned as complete if the intraocular pressure (IOP) was ≤21 and >5 mm Hg without any antiglaucoma medication and qualifi ed if IOP ≤21 and >5 mm Hg with or without antiglaucoma medications. Eyes not falling into qualifi ed success criteria were labeled as failure. Results: The median age at the time of trabeculectomy was 23 years (inter quartile range: 12, 28). The mean IOP reduced from 31.1 ± 8.6 mm Hg to 14.6 ± 4.4 mm Hg after trabeculectomy over a median follow up of 77 months (P < 0.001). The probability of complete success was 96% (95% CI: 77-99%) at one year, 88% (95% CI: 67-96%) at 2 years, which was maintained till 7 years and decreased to 79% (95% CI: 50-92%) at 8 years. The probability of qualifi ed success was 100% till 7 years and decreased to 90% (95% CI: 47-98%) at 8 years. The median number of postoperative medications reduced from 2 to 0 postoperatively (P < 0.001). Five eyes (21%) developed post-operative shallow anterior chamber (AC) requiring anterior chamber reformation, with 2 of these eyes needing lensectomy for resolution of this complication. Conclusion: Primary trabeculectomy had good success rate in glaucoma associated with microspherophakia. Post-operative shallow AC was a frequent complication needing additional intervention.

Background: In microspherophakia, abnormal laxity of the lenticular zonules leads to development of a spherical lens and possible subluxation. We evaluated long-term results of lens removal with scleral-fi xated intraocular lens (SFIOL) implantation in microspherophakia. Materials and Methods: Case series. SF IOLs were implanted in four consecutive patients with bilateral microspherophakia (eight eyes [three with pupillary block and secondary glaucoma who underwent immediate surgery and fi ve with only subluxation who underwent elective surgery]). Post-operative best-corrected visual acuity (BCVA), intraocular pressure (IOP) and lens position were evaluated periodically from day 1 to 18 months. Results: All patients were females (mean age 28 ± 7.03 years). In group 1 eyes (three eyes that presented with pupillary block), the mean BCVA improved from 0.008 decimals (preoperative) to 0.50 decimals (fi nal post-operative visit); in group 2 eyes (the other fi ve eyes), the mean BCVA improved from 0.12 ± 0.21 decimals to 0.73 ± 0.14 decimals. The preoperative mean IOP (54.53 ± 7.33 mmHg) in group 1 eyes was signifi cantly (P = 0.03) higher than that (16 ± 4.30 mm Hg) in group 2 eyes. At fi nal post-operative visit, the mean IOP (11.67 ± 2.88 mmHg) in group 1 eyes was not signifi cantly diff erent from that in group 2 eyes (13.0 ± 3.08 mmHg). All SFIOLs were well- centred at the fi nal visit. None of the patients encountered any peroperative or postoperative complications. Conclusions: SFIOLs may be an option for surgical management of microspherophakia.
RÉSUMÉ
We report the case of a 16-year-old woman with microspherophakia and secondary open angle glaucoma. The patient presented with a membrane dividing the anterior chamber into two segments without edema or Descemet's membrane detachment. Slit lamp biomicroscopy, Pentacam, and specular microscopy images were obtained. Double anterior chamber is primarily found in patients with anterior chamber anomalies when there is no history of surgery or trauma.
