Clinical evaluation of a new pupil independent diffractive MIOL lens with a ±2.75D near addition

This is a clinical outcome assessment after cataract surgery with implantation of multifocal intraocular lens implant IOL with a lower near addition (+2.75D) of 143 eyes of 85 patients aged between 40 to 83 years of age. The type of...

Biomaterials and Regenerative Medicines in Ophthalmology (Second Edition)

With advancement in science and technology in the last decade, the role of biomaterials and regenerative medicines has become increasingly important in the management of various ocular disorders. This book highlights the role of biomaterials in the restoration of vision...

OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....

Congenital cranial dysinnervation disorders (CCDDs)

The term congenital cranial dysinnervation disorder (CCDD) was introduced by Gutowski et al. in 2003 to describe strabismus conditions that result from developmental error in innervation of some of the extraocular muscles. Examples of these conditions include Duane’s syndrome and...

My ophthalmic elective: focusing on myopia in Taiwan

The authors describe their elective experience and delve further into high myopia, an emerging ophthalmic disease that is increasingly recognised in and outside Asia. The medical school elective programme presents an opportunity for students to conduct learning in their chosen...

How does low-concentration atropine reduce progression of myopia?

This is a double-blind, randomised, placebo-controlled trial evaluating the effects of low-concentration atropine (0.05%, 0.025%, 0.01%) on ocular biometrics of myopic children. The aim is to determine what aspect of ocular biometrics low-concentration atropine influenced in reducing the progression of...

Fixed or variable Muller’s muscle resection

This is a retrospective analysis of 60 patients who underwent posterior approach ptosis surgery utilising a Muller’s muscle resection. The study compares those who underwent a fixed resection length of 7mm of Muller’s muscle with those having a variable resection...

Micropulse vs. continuous wave trans scleral diode cyclophotocoagulation in refractory glaucoma

Continuous wave cyclophotocoagulation (CWCPC) delivers continuous high intensity energy to the ciliary body in an attempt to reduce aqueous secretion and hence lower IOP. It is often used as a treatment of last resort due to the potential side-effects of...

Corneal dystrophies simplified

Based on biomicroscopic and histopathologic features, corneal dystrophies can be broadly classified into epithelial, Bowman’s layer / anterior stromal, stromal, and endothelial dystrophies. Corneal dystrophies are a group of inherited, bilateral, gradually progressing, non- inflammatory conditions caused by accumulation of...

Cycloplegic autorefraction versus cycloplegic retinoscopy

This cross-sectional study compared cycloplegic autorefraction using VISUREF 100 table top and keratometer device (Zeiss) versus cycloplegic retinoscopy. The study included 47 children (94 eyes) of which 55 eyes were excluded because of ocular disease or not aged three to...

Outcomes and complications of supramaximal levator resection

This is a report of 35 children with unilateral congenital ptosis who underwent a supramaximal levator resection, involving extensive dissection of levator including cutting Whitnall’s ligament. The average preoperative margin reflex distance to the upper lid (MRD1) was 0.5mm, and...

Proprioception and ptosis

This is a small prospective study investigating the effect of proprioceptive factors on upper lid height. Eight unilaterally anophthalmic patients with ocular prostheses and normal lid heights had standardised photographic measurements taken of their eyelid and brow positions. Three sets...
