Intra-lenticular lens aspiration in paediatric cases with anterior dislocation of lens

[Latest advances in the diagnosis and treatment of Marfan syndrome]

Marfan syndrome (MFS) is a multisystem connective tissue disease with autosomal dominant inheritance. It is mainly caused by FBN1 gene mutation and often has different clinical manifestations. Neonatal MFS is especially rare with severe conditions and a poor prognosis. At present, there is still no radical treatment method for MFS, but early identification, early diagnosis, and early treatment can effectively prolong the life span of patients. This article reviews the latest advances in the diagnosis and treatment of MFS.

Outcomes of surgical intervention in cases of ectopia lentis

Purpose:

To evaluate the outcomes of surgical intervention in cases of ectopia lentis.

Methods:

This retrospective study included all cases of ectopia lentis that presented between June 2015 and March 2019 in a tertiary care center. They were reviewed retrospectively. The corrected distance visual acuity (CDVA), severity of lens subluxation, type of surgery, intra-operative and post-operative complication, and specular count were recorded.

Results:

Seventy-eight eyes of 57 cases with a mean age at surgery of 14.73 years were analyzed. Intra-lenticular lens aspiration was the most common (n-62/78; 79.5%) surgical procedure followed by lens aspiration, intra-capsular cataract extraction, phaco-aspiration, and pars-plana lensectomy. Simultaneous intra-ocular lens (IOL) implantation was performed in 46.2% (n-32/78) of the eyes. The mean CDVA improved from 0.85 ± 0.55 logMAR to 0.44 ± 0.29 logMAR at 6 weeks follow-up. The post-operative CDVA was significantly better in the pseudo-phakic group compared to the aphakic group (p-0.02). The patient’s age at the time of surgery and the degree of subluxation did not impact the final visual outcome. Intra-operative complication included vitreous hemorrhage (n-1) and lens matter drop (n-1). Post-operative complications were noted in 26.9% of the eyes (n-21/78) with a higher complication rate in the pseudo-phakic group (p-0.00). A second intervention was required in 7.7% of the eyes (n-6/78).

Conclusion:

Age and degree of subluxation at the time of surgery do not influence the final visual outcome in cases of ectopia lentis undergoing lens extraction surgery. IOL implantation results in better visual outcomes but is associated with a high complication rate.

Intraoperative optical coherence tomography-guided release of lenticulo-corneal adhesion and lens aspiration in anterior dislocation of lens with corneal edema

Purpose:

To describe the outcome of microscope integrated optical coherence tomography (MiOCT) guided removal of lenticulo-corneal adhesion and intralenticular lens aspiration (ILLA) in cases with anterior dislocation of the crystalline lens and corneal edema.

Methods:

MiOCT-guided ILLA was performed in three eyes of two cases of homocystinuria with spontaneous anterior dislocation of lens and corneal edema. Lenticulo-corneal adhesion was noted intraoperatively, which was not apparent pre-operatively. The lenticulo-corneal adhesion could be successfully peeled using intravitreal forceps and viscodissection with visco-dispersive viscoelastic under the guidance of MiOCT.

Results:

In all cases, the lenticulo-corneal adhesion could be successfully removed without any complication such as Descemet tear or worsening in corneal edema. Improvement in visual acuity was noted in all cases with resolution in corneal edema by 1 week.

Conclusion:

MiOCT-guided ILLA can be extremely useful in cases of lenticulo-corneal adhesion especially in cases with corneal edema.
