Neurofibromatosis type 1 features

The aim in this study was to identify the incidence and de nova mutation rate of Neurofibramatosis type 1 (NF1) and describe the ocular and non-ocular findings in a population-based cohort of patients diagnosed over a 30-year period. The study...

Effect of long-term scleral contact lenses on corneal topography, tear film and impression cytology in keratoconus

This study of 16 keratoconus patients aimed to investigate the impact of long-term scleral contact lens (ScCL) wear on corneal curvature, corneal thickness, tear film function and ocular surface in patients with keratoconus. Corneal topography, tear osmolarity test, Schirmer 1...

Differential diagnosis of retinoblastoma and pseudo retinoblastoma

The authors reviewed the rate of pseudo retinoblastoma (PRB) among cases referred for suspicion of RB at a tertiary referral centre in Turkey and the distribution of PRB cases according to age. This was a retrospective study of 549 patients...

Progression of macular atrophy on long-term anti-VEGF therapy for AMD

This retrospective study evaluated the progression of macular atrophy in 53 eyes of 53 patients receiving AntiVEGF Therapy for age-related macular degeneration (nAMD), for at least six years. None of the patients had any macular atrophy (MA) at presentation. MA...

OCT prognostic factors in AMD patients with peripapillary choroidal neovascularisation

In this retrospective study the authors aimed to investigate the correlation between optical coherence tomography (OCT) findings and visual acuity outcomes after treatment with intravitreal bevacizumab (IVB) injections for age-related macular degeneration (AMD) patients with peripapillary choroidal neovascularisation (PPCNV). Data...

Atrophy and anti-VEGF

The aim of this study was to investigate treatment factors, along with ocular and systemic factors for their association with macular atrophy (MA) incidence in eyes with neovascular age-related macular degeneration (nAMD) treated with anti-VEGF aflibercept or ranibizumab according to...

Outcomes of corneal cross-linking in paediatric patients compared to fellow untreated eyes

This retrospective cohort study evaluated long-term visual, refractive, topographic and safety outcomes of corneal cross-linking (CXL) in patients younger than 18-years-old with keratoconus. The study included all consecutive paediatric patients who underwent epithelium-off CXL treatment for keratoconus at the study...

Effects of ML4 on the eye

Mucolipidosis type IV (ML4) is an autosomal recessive lysosomal storage disease and is caused by variants of the MC0LN1 gene. It often presents in young individuals with eye and ocular adnexa issues. The authors present a case report and literature...

Bioengineered human tissue

This is a literature review of the current status of tissue engineering related to ocular and oculoplastic reconstructive surgery. The authors describe the process of bioengineering for tissue reconstruction. The aim is to reproduce functional tissue by the use of...

Retinal structural features of CMV retinitis

Confocal adaptive optics (AO) technology has enabled cellular level retinal imaging, including imaging of photoreceptors and blood flow. Adaptive optics scanning laser ophthalmoscopy (AOSLO) is a technology that provides high resolution and high contrast retinal images by correcting ocular aberrations....

Choroidal folds

Choroidal folds are undulations of the choroid, Bruch’s membrane and pigment epithelium, with wrinkling of the overlying retina. They may be idiopathic but can also be caused by a number of different conditions. Case report A 60-year-old male patient was...

Silent keratitis in failed graft

This study examined rates of asymptomatic keratitis in failed full thickness corneal grafts, which were not picked up clinically preoperatively. During a five year period 53 penetrating keratoplasties (PK) were performed for long-standing graft decompensation with stromal opacity and /...
