V pattern surgery

Inferior oblique (IO) muscle belly transposition involves fixing the belly of the IO to the sclera at 5mm posterior to the temporal insertion of the inferior rectus (IR). This study reports the clinical outcomes of bilateral surgery to treat V...

BT for retinal detachment strabismus (2020)

The authors report updated experience on factors influencing botulinum toxin (BT) outcomes for strabismus following retinal detachment surgery. This was a retrospective review of 32 patients with follow-up of 20 months (1-132). Mean age at BT injection was 44 years...

Detailed overview of diplopia causes and outcomes for a single tertiary care centre

The purpose of this study was to study the aetiology, progression and outcome in patients with binocular diplopia presenting to the ophthalmology department of a tertiary care centre in India. The study had a prospective observational design where all patients...

IOL power in short eyes

Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...

Augmented surgery for monocular elevation deficiency

The outcomes are described for augmented lateral rectus superior transposition in cases of acquired monocular elevation deficiency (MED) associated with large hypotropia in primary gaze. The lateral rectus was transposed superiorly and reinserted on sclera between the temporal margin of...

BESTi: a new index to detect subclinical keratoconus

In this multicentre, case-control study, the authors develop a new index, named Boosted Ectasia Susceptibility Tomography Index (BESTi), to detect early cases of keratoconus. This index was derived from multiple logistic regression analysis of 22 variables of tomography scans. The...

Detection of SO tendon abnormality versus atrophy

This study aimed to evaluate patterns of binocular misalignment in primary gaze, lateral and vertical gaze, and head tilt in patients showing head-tilt dependent hypertropia associated with discontinued superior oblique (SO) tendon but without SO muscle atrophy, versus patients with...
