Moebius Syndrome with Hypoglossal Palsy, Syndactyly, Brachydactyly, and Anisometropic Amblyopia.

Moebius syndrome is a rare cause of congenital facial and abducens palsy. It is sometimes associated with musculoskeletal abnormalities and other cranial nerve palsies. Genetics and ischemic insults to the fetus are considered to be the cause of this syndrome. We report here a 12-year-old female patient who was presented to us with poor cosmesis of her face, with associated decreased vision and lagophthalmos in her left eye. She didn't have any signs of exposure keratopathy in the affected eye. Her best-corrected vision was 20/20 and 20/60 in right and left eyes respectively. The cause of decreased vision in her left eye was found to be anisometropic amblyopia, due to asymmetric hyperopic astigmatism in her eyes. She did not report diplopia in any gaze position. Examination of her cranial nerve revealed left facial, abducens, and hypoglossal nerve palsy, leading us to the diagnosis of Moebius syndrome. Apart from that, she had syndactyly in one of her hands, and brachydactyly in both. Since the eyes were straight in their primary position, no surgical intervention was carried out for her lagophthalmos, which was measured to be only 2 mm. This was to prevent any post-operative iatrogenic ptosis. The condition requires a multidisciplinary approach involving the opinions of a neuro-ophthalmologist, strabismologist, and oculoplastics for the management of the complications associated with the disease.

Pathophysiology, diagnosis, and management of glaucoma associated with Sturge-Weber syndrome.

PURPOSE: Sturge-Weber syndrome (SWS), also known as encephalotrigeminal angiomatosis, is a condition which includes leptomeningeal hemangioma, facial angiomatosis or nevus flammeus, and ocular changes. SWS can lead to severe complications of anterior segment involving conjunctiva and eyelids, whereas posterior segment of the eye may also be affected by diffuse choroidal hemorrhages. This article was written with the objectives to determine the pathophysiology, diagnosis, and treatment of glaucoma associated with this rare and challenging disorder. METHODS: A detailed literature search was conducted on PubMed, EMBASE, Cochrane Library, and Google Scholar using the key words. Forty-five articles matched our inclusion criteria that were included in this systematic review. RESULTS: Glaucoma is the one of the commonest ocular manifestations of SWS. It is caused by anterior chamber malformations, increased pressure in the episcleral veins, and changes in ocular hemodynamics. Glaucoma associated with SWS is usually congenital but can develop adults as well. The treatment of glaucoma associated with SWS is quite challenging because of early-onset, severe visual field impairment at the time of diagnosis, and unresponsiveness to standard medical treatment. Several surgical procedures have been devised but the long-term control of the intraocular pressure and visual function remain unsatisfactory. Modifications in the filtration surgery techniques and use of newer anti-fibrotic agents have produced good control of intraocular pressure. CONCLUSION: Management of glaucoma associated with SWS is multi-dimensional and needs both medical and surgical interventions for better control. The treatment should be devised on case to case basis depending upon the intraocular pressure, stage of the disease, and type of glaucoma.

Comparison of characteristics of femtosecond laser-assisted anterior capsulotomy versus manual continuous curvilinear capsulorrhexis: A meta-analysis of 5-year results.

OBJECTIVE: To perform a meta-analysis on the precision and safety of femtosecond laser-assisted anterior capsulotomy versus conventional manual continuous curvilinear capsulorrhexis. METHODS: This meta-analysis was conducted from February 2010 to November 2014. Literature search on PubMed, Google Scholar, ExcerptaMedica database and Cochrane Library was done to identify randomised controlled trials and case-control studies. SPSS 20 was used for data analysis. RESULTS: Of the 10 articles included, there were 3(30%) randomised controlled trials and 7(70%) non-randomised controlled trials. The meta-analysis was based on a total of 2,882eyes. Of them, 1,498(51.97%) underwent femtosecond laser-assisted capsulotomy and 1,384(48.02%) underwent manual continuous curvilinear capsulorrhexis. The diameter of the capsulotomy and the rates of anterior capsule tear showed no statistical difference between the femtosecond laser group and the manual capsulorrhexis group (p=0.29 and p=0.68). In terms of circularity of capsulotomy, femtosecond laser group had a more significant advantage than the manual capsulorrhexis group (p<0.001). CONCLUSIONS: Femtosecond laser performed capsulotomy with more precision and higher reliability than the manual continuous curvilinear capsulorrhexis.

Femtosecond laser assisted cataract surgery, beginning of a new era in cataract surgery.

The purpose of this article is to analyze and understand the mechanism of action, effectiveness, cost and time benefits, advantages and disadvantages of the femtosecond laser (FSL) assisted cataract surgery. A PubMed search was done using the topic and the keywords. Research shows considerable improvements in corneal incisions, anterior capsulotomy, and phacofragmentation using FSL. We will also discuss and compare FSL with conventional cataract extraction techniques in terms of both short-term and long-term advantages and disadvantages. Limitations of the studies reviewed include small sample size and short-term follow-up. The major dilemma is still considered to be its heavy financial feasibility to date.
