OCTA FAZ measurements in vein occlusion

Previous studies have confirmed that foveal avascular zone (FAZ) enlargement is correlated with visual acuity impairment in patients with retinal vein occlusion (RVO). This current study aimed to evaluate the OCT angiography parameters: the area of FAZ, foveal and parafoveal...

ROP ocular outcomes after Bevacizumab treatment

The relationship between refractive outcomes and biometric parameters were evaluated following intravitreal Bevacizumab (IVB) monotherapy. Sixty-three infants were grouped into 1) infants treated with VB monotherapy for ROP (six with zone 1 and eight with posterior zone II retinopathy of...

Conventional vs. accelerated cross-linking

The Dresden protocol of 3mW/cm2 irradiance for 30 minutes has been extensively studied and has shown advantageous clinical and topographical results. However, this protocol is time-consuming and therefore accelerated CXL using higher irradiance to shorten treatment duration has emerged. The...

Association of asthenopia and heterophoria

Heterophoria varies over time and asthenopic symptoms may be greater when the heterophoria is larger. Thus a close intra-individual correlation may exist between heterophoria and discomfort during reading. The authors investigated the variability of both parameters in 20 individuals who...

Dry eyes after photorefractive keratoplasty

This study examined changes in tear break up time (TBUT), Schirmer test, tear osmolarity and dry eye questionnaire (OSDI) score from prior to photorefractive keratoplasty (PRK), to two months and four months postoperatively. Fifty eyes of 25 patients were examined....

Repeated orbital decompression surgery

This is a retrospective review of nine redo orbital decompressions in six patients. All operations were performed for dysthyroid optic neuropathy, both initially and when repeated. The interval between first and redo decompressions varied from one to 15 years and...

GP contact lenses in nystagmus

The purpose of this study was to quantify and evaluate the effect of rigid gas permeable contact lenses (CLs) on visual acuity, contrast sensitivity and motor parameters of involuntary eye movements in hyperopic patients with infantile nystagmus syndrome (INS). This...

Cataract surgery and circadian photoentrainment

The study authors sought to investigate the possible effects of circadian photoentrainment following cataract. This was a randomised clinical trial, where 76 eyes of 76 patients (with bilateral cataract) were randomised to blue-blocking or neutral intraocular lenses (IOLs). Outcome measures...

Clinical and neuro-ophthalmologic predictors of visual outcome in idiopathic intracranial hypertension

This prospective study of 40 patients aims to assess visual morbidity in patients with idiopathic intracranial hypertension (IIH). Final visual outcome of patients was compared with clinical and neuro-ophthalmic parameters such as visual acuity, visual field, contrast sensitivity, retinal nerve...

Visual outcomes, visual fields and optical coherence tomography in paediatric craniopharyngioma

This study reviews the visual outcomes of ten patients under the age of 18 years with craniopharyngioma. The paper also reviews the correlation between visual field (VF) testing and optical coherence tomography (OCT) examination and evaluates the role of OCT...
