Success rates of primary and revision transcanalicular DCR surgery
Transcanalicular laser DCR is a relatively rare procedure compared to more conventional external or endo-nasal techniques. In this article the authors examine the outcomes of revision surgery following failed transcanalicular diode laser dacryocystorhinostomy (TCDL DCR), comparing a conventional external revision...
The prevalence of macular cysts in patients with clinical cone-rod dystrophy determined by spectral domain optical coherence tomography
Cone-rod dystrophy is a progressive photoreceptor disorder which has multiple inheritance patterns. It is rare, with a prevalence of 1 in 40,000. Macular cysts are well recognised in other photoreceptor conditions such as retinitis pigments and choroideraemia, while they are...
Molecular genetics of achromatopsia
Achromatopsia is a rare autosomal recessive disorder of the cone photoreceptors. Typical characteristics of affected patients include the inability to distinguish colours, impaired visual acuity, photophobia and nystagmus. The condition is said to be more frequent in the Pingelapese population...

Congenital defects include rudimentary eyelids, macrostomia, ambiguous genitalia and campodactyly. Neonates are at risk of severe corneal exposure without intervention. Previous reports have...
Profile of sympathetic ophthalmia (SO)
The authors undertook this study to examine the clinical profile of patients aged <18 years with SO over the past 20 years. This was a hospital-based retrospective study from 1997 to 2017. SO is a diagnosis of bilateral panuveitis following...
Risk of CNV related to angioid streaks in PXE
This retrospective cross-sectional study investigated 301 patients with pseudoxanthoma elasticum (PXE) for prevalence of choroidal neovascularisation (CNV) and macular atrophy. Some patients were excluded due to missing or poor-quality imaging or the fact that they didn’t have angioid streaks, leaving...
Sebaceous gland carcinoma
This is a review of 241 patients diagnosed with periocular sebaceous gland carcinoma which investigates whether age at presentation influences either the clinical presentation or the outcomes of treatment. Twelve percent of patients were classified as young (<40 years old),...
A retrospective medical notes review in patients with poor vision due to NAION
Very severe visual loss (hand movements or less) is typical of arteritic anterior ischaemic optic neuropathy (AION) and relatively rare in non-arteritic AION (NAION). This study aimed to report the frequency of very poor visual acuity (VA) in NAION. The...
Clinical features and mortality of endogenous panophthalmitis in China
This longitudinal cohort study aimed to report the clinical features, treatment strategy, and mortality of 15 consecutive patients (16 eyes) with endogenous panophthalmitis (EP) at a tertiary medical centre of the largest eye centre in Northern China. Mean age was...
Ocular adnexal mantle cell lymphoma
In this study the authors compare primary ocular adnexal (OA) mantle cell lymphoma (MCL) with initially systemic MCL occurring over a 30-year period. MCL is a rare form of lymphoma accounting for 5-11% of OA lymphomas and therefore knowledge of...
Narrative review of opsoclonus myoclonus ataxia syndrome following COVID-19
Opsoclonus myoclonus syndrome (OMS) / opsoclonus myoclonus ataxia syndrome (OMAS) is a rare central nervous system manifestation of COVID-19, but an increasing number of articles have reported patients in whom COVID-19 was complicated by OMS / OMAS. This narrative review...
