Dacryocystosclerotherapy as an alternative to dacryocystectomy

In this article, the authors evaluate the role of sclerosing agents in dacryocystosclerotherapy (DCST) and aim to see whether it is an alternative to dacryocystectomy (DCT) in a specific group of patients. Thirteen lacrimal drainage systems of 10 patients with...

Conjunctival inflammation in glaucoma patients

Numerous studies have demonstrated that topical medications and preservatives used for the management of glaucoma can induce significant histopathologic and inflammatory changes in the ocular surface. This study describes an increased expression of major histocompatibility complex class II antigen HLA-DR,...

Therapy for limbal stem cell deficiency: cell fate after limbal stem cell transplants

“The beauty of scientific research lies in that the search for answers often yields yet more questions.” A large body of evidence points to the corneoscleral limbal location as the repository of putative epithelial stem cells [1]. Thoft proposed the...

Diffuse lamellar keratitis

This study group reviewed cytokine- and chemokine-mediated mechanisms of diffuse lamellar keratitis (DLK) after lamellar corneal surgical procedures. DLK can occur early or late (months to decades) after all lamellar corneal surgeries, including laser in situ keratomileusis, small incision lenticule...

Resurfacing the ocular surface

The ocular surface (OS) is an anatomical and functional unit made of the tear film, the conjunctival, limbal and corneal epithelium, the lacrimal, mucous and meibomian glands and the lids and blink reflex. The tear film is composed of a...

Amnion-assisted conjunctival epithelial redirection (ACER): Enhancing stem cell transplantation treatment of total limbal stem cell deficiency

An exploration of Professor Harminder Dua’s recent work using a technique called amnion-assisted conjunctival epithelial redirection (ACER) to aid the success of conjunctival-limbal grafting procedures. ACER provides a refined way to use amniotic membrane (amnion), such as Omnigen® (NuVision® Biotherapies,...

Q&A: Mr Goel and Mr Loomba on alcohol delamination and phototherapeutic keratectomy (PTK) for the treatment of recurrent corneal erosion syndrome

Recurrent corneal erosion syndrome is a common, recurrent condition caused by abnormal epithelial adhesion to the underlying basal lamina. Spontaneous breakdown of the corneal epithelium can lead to the sudden onset of ocular pain, blurred vision, tearing and photophobia, typically...

Exudative age-related macular degeneration

The authors looked at macular lesions in eyes with newly diagnosed exudative age-related macular degeneration. The eyes of 23 patients were included and tested for visual acuity, contrast sensitivity, microperimetry, optical coherence tomography (OCT) and fluorescein and indocyanine green angiography....

RPE tears in cases of IPCV

The aim of this study was to investigate the occurrence, characteristics, management and prognosis of retinal pigment epithelium (RPE) tears in patients with polypoidal choroidal vasculopathy (PCV). Medical records of previous cases were reviewed over an eight-year period from a...

OCTA use in CNV associated with CSR

The aim of this study was to assess the rate of choroidal neovascularisation (CNV) in chronic central serous chorioretinopathy (CSR) patients with flat irregular pigment epithelial detachments (PEDs) by optical coherence tomography angiography (OCTA). Data of all consecutive patients with...

Retinal morphology after PASCAL PRP treatment

The authors of this prospective cohort study set out to report the changes on Spectral Domain-OCT of PASCAL panretinal laser photocoagulation (PRP) treatment for proliferative diabetic retinopathy (PDR) or severe nonproliferative DR (NPDR) and the retinal morphology, from one hour...

Anaesthetic drops abuse

A 67-year-old retired female nurse presented with persistent, bilateral, non-healing (>6 weeks) corneal ulcers and stromal ring infiltrates (Figures 1 and 2). The epithelial defects were the result of chemical burns caused by her contact lenses which had been stored...
