Ocular surface and meibomian gland changes in cicatricial conjunctival disease

The authors evaluate long-term structural and functional meibomian gland and lid margin changes in a retrospective study of 64 patients (64 eyes) with chronic cicatricial conjunctival diseases (CCDs), including ocular cicatricial pemphigoid (OCP; n=22), Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS-TEN; n=24),...

Visual and anatomic outcomes in delayed-onset endophthalmitis after glaucoma surgery

The authors evaluate visual and anatomical outcomes in a retrospective case series of 15 eyes from 15 patients treated for delayed-onset endophthalmitis following incisional glaucoma surgery. The study included patients presenting at a tertiary referral centre between 2013 and 2023...

Handbook of Retinal Disease: a case based approach

This book is suitable for all doctors, particularly ophthalmologists, who want to further their knowledge and understanding of retinal pathologies and keep up to date. The case-based format is effective in evoking an interactive approach to differential diagnosis. The tabulation...

Quarter DMEK

This case report describes a novel technique where one quarter of Descemet’s membrane (DM) was transplanted during a quarter-descemet membrane endothelial keratoplasty (DMEK) procedure. DMEK graft was prepared from a 58-year-old corneo-scleral donor after one week in culture. Peripheral DM...

Retinoblastoma chemotherapeutic drugs and their toxic effects on RPE cells

There is reported clinical evidence of retinal pigment epithelium (RPE) alterations after intra-arterial (IAC) and intravitreal chemotherapy (IViC) of retinoblastoma. The purpose of this study was to investigate the cellular toxic effects of melphalan, topotecan and carboplatin on the RPE...

Incidence and risk factors of late in the bag intraocular lens dislocation

The aim of this study was to identify risk factors for late in the bag dislocation over a 21 year period. Worldwide the incidence varies from 0.05% to 3.0%. In this Swedish study they report an increase in incidence in...

Effect of anti-VEGF treatment on PED morphology

This retrospective study of 30 eyes assessed the effect of anti-VEGF on morphology of pigment epithelial detachments (PED) secondary to age-related macular degeneration (AMD). Thirty eyes of 28 patients with PED were compared to 30 eyes of 30 patients with...

Squamous metaplasia of conjunctival epithelial cells with soft contact lens wear versus non-lens wearers

Conjunctiva is composed of non-squamous epithelial cells interspersed with goblet cells, which is a secretory epithelium. Squamous metaplasia is a transformation to non-secretory epithelium, ‘keratinised’ and enlargement of the conjunctival non-goblet cells and relatively shrunken nuclei are seen on impression...

Macular slippage following macular hole surgery

The treatment of macular holes now involves peeling the internal limiting membrane (ILM) as well as vitrectomy and gas tamponade. It has been noted in previous studies that following an ILM peel the morphology of the macula is different. Tadayoni...

Comparison of SIA from femtosecond laser and manual CCIs for cataract surgery

This study group compared the differences in surgically induced astigmatism (SIA) vector, flattening effect, torque and wound architecture following both femtosecond laser and manual clear corneal incisions (CCIs). A double-armed, randomised, prospective case series was conducted. Cataract surgery was performed...

Characteristics of limbal lymphatic vasculature on confocal microscopy

This ex vivo study aims to describe the morphological characteristics of the human limbal lymphatic vasculature using confocal microscopy and immunofluorescence. Twelve corneal specimens are obtained from human donor eyes. These corneal buttons are not suitable for transplantation due to...

Long-term effect of YAG LPI on corneal endothelium in PACS

This is a single-centre randomised controlled trial of 875 patients with bilateral primary angle closure suspect (PACS) who received YAG laser iridotomy (LPI) prophylactic treatment in one eye randomly and the fellow eye served as control over 72 months. Central...
