Stem cell transplantation and pterygium surgery

Pterygium is a benign, fibrovascular overgrowth of bulbar conjunctiva extending onto the cornea and has been associated with ultraviolet (UV) light exposure. The prevalence of pterygium worldwide varies between geographical zones but has been reported to range between three and...

Retinal pigment epithelium tears

In this paper the authors review the current knowledge of retinal pigment epithelium (RPE) tears. Although rare these can cause loss of visual acuity. They can occur spontaneously in pigment epithelial detachment (PED) due to occult choroidal neovascularisation (CNV), retinal...

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...

Preoperative RPE alterations in macular holes

This retrospective interventional case series from Japan assessed whether preoperative alterations of the retinal pigment epithelial (RPE) in idiopathic macular holes correlated with postoperative functional and morphological changes in the macula. Fifty-nine eyes had preoperative Spectralis OCT using the ‘detailed’...

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...

CD40L activation of human RPE cells

Age-related macular degeneration (AMD) is the leading cause of reduced visual acuity in the elderly worldwide. The risk factors involved in AMD include smoking and diet, while genetics have been shown to have a significant role. Recently a link between...

Type 3 macular neovascularisation (MNV) due to age-related macular degeneration

This paper systematically reviews and summarises the current knowledge on type 3 neovascularisation due to age-related macular degeneration which is defined as neovascularisation originating from the retinal deep capillary plexus that grows towards the outer retina often penetrating the level...

Quiz Apr/May 2023

History A 76-year-old female presented at her local district general hospital with right decreased visual acuity, glare, and foreign body sensation, in addition to longer-term dry eyes. She was otherwise well. Her past medical history included hypertension. On examination: vision...

Recurrent corneal erosions secondary to isotretinoin use

Isotretinoin (13–cis-retinoic acid) is the first line treatment for moderate to severe nodulocystic or papulopustular acne [1,2]. Although it is a safe medication, it has several adverse side-effects, including ophthalmic manifestations, as shown in Table 1 [3]. These side-effects need...

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 /...

Nanofiber-based hydrogels prevent capsular opacification

Lens refilling is the replacement of the lens with a silicone polymer in an otherwise intact lens capsule. However, capsular opacification (CO), resulting in reduced visual acuity, is a major complication of these injectable accommodating lenses. Opacification is due to...

Vision loss during Eylea treatment for AMD

This report investigated patients who lost more than two lines of vision despite periodic injections of aflibercept and explored the factors associated with vision loss. One hundred and ninety-six eyes were included in this study over a two year period....
