Single muscle surgery for hypertropia
The authors undertook partial tenotomies combined with graded marginal recession of single vertical rectus muscles to treat small angle hypertropia in four adults with fusion potential. They report dose response, surgical technique and outcomes. Dose response closely matched the theoretical...
Development of Browns syndrome after acquired fourth nerve palsy
Seven cases are described of spontaneous Browns syndrome with onset months after fourth nerve palsy (NP), without evidence of direct trauma, to report pathophysiological explanations for these cases. There were 5 males and 2 females with mean age of 57...
Iranian prevalence of convergence / accommodative disorders
The aim of this study was to investigate the frequency of accommodative and convergence disorders in an optometric clinical population and ascertain tests with the highest sensitivity and specificity in detecting these anomalies. The authors gathered information on symptoms, near...
15 prism test for anisometropic amblyopia
The authors aimed to investigate the accuracy of the 15^ base in prism test (BIPT) in detecting amblyopia in anisometropic patients. This was a retrospective study in which the 15^BI was placed before the right eye followed by the left...
Testing fusional amplitude
The purpose of this study was to evaluate the effects of varied testing distance and order of testing on fusion amplitudes in subjects with normal eye examinations, along with impact of examination encouragement and subject level of alertness. Average age...
AC/A non-linearity
This study investigated whether or not the response accommodative convergence to accommodation (AC/A) ratio in 30 visually normal subjects is linear with lens presentation order counterbalanced. Accommodative response was measured using the Shin Nippon SRW 500 infrared autorefractor. Accommodation was...
Fusional vergence measurement
This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...
Age versus heterophoria and fusional vergence measures
This study aimed to establish the relationship between age, horizontal heterophoria, horizontal vergences, positive / negative fusional vergence and vergence facilities. The study recruited 112 subjects aged 39.8 ±14.97 years (range 18-65) of which 54.5% were female. There were 49...
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...
Treatment of vertical diplopia in the reading position
This paper describes the use of slab-off prisms for the treatment of vertical diplopia in the reading position. The following data were collected: main symptom complaint, visual acuity, refractive error, binocular vision including sensory fusion and stereoacuity, alternating cover test...Unravelling ocular motility
Ocular motility can often be a slightly abstract concept during the earlier years of ophthalmology training. A large variance on what embodies normality; mythical concepts like fusion and binocular vision, examination techniques that can be fiddly, and complex neuroanatomy all...
