TL;DR: The hypothesis that patients with keratoconus have a shorter life expectancy owing to underlying connective tissue related disease was tested and results show no significant difference between the general population mortality rate and that of the keratconus sample even with adjustment for social class.
Abstract: It is observed that few patients over the age of 60 regularly attend the keratoconus clinic at Moorfields Eye Hospital. The hypothesis that patients with keratoconus have a shorter life expectancy owing to underlying connective tissue related disease was tested. From patient records a sample of 337 keratoconus patients aged at least 40 years by 1991 were identified, of which 279 were living, 13 were deceased, and 45 were untraceable. The mortality rate for keratoconus patients was compared with that of the general population using actuarial English life tables. Results show no significant difference between the general population mortality rate and that of the keratoconus sample even with adjustment for social class. Possible explanations for the non-attendance of older patients are discussed.

TL;DR: The British annual incidence of primary congenital glaucoma diagnosis is comparable to that reported for other similar populations and Ethnic minorities from South Asia are at significantly increased risk of PCG.
Abstract: PURPOSE. Pediatric glaucoma is a rare, potentially blinding condition, yet, in the United Kingdom, there is a paucity of contemporary epidemiologic and clinical data regarding this condition. The British Infantile and Childhood Glaucoma (BIG) Eye Study is the first national population-based study conducted to examine the incidence, detection patterns, current management, and intraocular pressure (IOP) control at 1 year in children with newly diagnosed glaucoma in the United Kingdom. METHODS. A prospective study was conducted wherein children in the United Kingdom and Republic of Ireland aged 16 years with newly diagnosed primary or secondary glaucoma, were identified by consultant ophthalmologists through active surveillance from December 2001 until November 2002. Eligible cases were re-evaluated 12 months after notification. RESULTS. Of the 99 eligible children with newly diagnosed glaucoma, 47 had primary and 52 secondary glaucoma. The annual incidence of diagnosis of primary congenital glaucoma (PCG) in Great Britain was 5.41 in 100,000 (1/18,500) live births and in the Republic of Ireland, 3.31 in 100,000 (1/ 30,200). The incidence of PCG in children of Pakistani origin was almost nine times that of Caucasians. IOP control of 21 mm Hg was achieved in 94% with medications (60% without medications) in cases of PCG and in 86% with medications (28% without medications) in cases of secondary glaucoma. CONCLUSIONS. The British annual incidence of PCG diagnosis is comparable to that reported for other similar populations. Ethnic minorities from South Asia are at significantly increased risk of PCG. Successful IOP control in PCG after surgery in Britain is comparable to that in the published literature. (Invest Ophthalmol Vis Sci. 2007;48:4100‐4106) DOI:10.1167/

TL;DR: The retinal-specific guanylate cyclase gene (RETGC-1), which maps to within an 8 cM interval on chromosome 17p12-p13, was screened for mutations within this family and in a panel of small families and individuals with various cone and cone- rod dystrophy phenotypes.
Abstract: The dominant cone‐rod dystrophy gene CORD6 has previously been mapped to within an 8 cM interval on chromosome 17p12‐p13. The retinal-specific guanylate cyclase gene (RETGC-1), which maps to within this genetic interval and previously was implicated in Leber’s congenital amaurosis, was screened for mutations within this family and in a panel of small families and individuals with various cone and cone‐ rod dystrophy phenotypes. A missense mutation (E837D) was identified in affected members of the CORD6 family, as well as a second missense mutation (R838C) in three other families with dominant cone‐rod dystrophy. RETGC-1 is only the fourth gene to be implicated in cone‐rod dystrophy and this is the first report of dominant mutations in this gene.

TL;DR: The aim of this study was to compare the efficacy and safety of micropulse and continuous wave diode transscleral cyclophotocoagulation in refractory glaucoma.
Abstract: Background
The aim of this study was to compare the efficacy and safety of micropulse and continuous wave diode transscleral cyclophotocoagulation in refractory glaucoma.
Design
Randomized, comparative, exploratory study in a tertiary hospital setting.
Participants
Patients with refractory, end-stage glaucoma.
Methods
Forty-eight patients were randomized to either treatment. The intraocular pressure, visual acuity, number of medicines and repeat treatment were monitored for 18 months. Complications that include visual acuity decline, prolonged anterior chamber inflammation, phthisis bulbi, scleral thinning and ocular pain were noted.
Main Outcome Measure
Intraocular pressure between 6 and 21 mmHg and at least a 30% reduction with or without anti-glaucoma medications after 18 months.
Results
A successful primary outcome was achieved in 75% of patients who underwent micropulse cyclophotocoagulation and 29% of patients who received continuous wave cyclophotocoagulation after 12 months (P < 0.01). At 18 months, successful outcome was 52% and 30% (P = 0.13), respectively. The mean intraocular pressure was reduced by 45% in both groups (P = 0.70) from a baseline of 36.5 mmHg and 35.0 mmHg (P = 0.50) after 17.5 ± 1.6 months (range 16–19) follow up. No significant difference in retreatment rates or number of intraocular pressure lowering medications was noted. The ocular complication rate was higher in continuous wave treated eyes (P = 0.01).
Conclusion
Diode transscleral cyclophotocoagulation in both micropulse and continuous modes was effective in lowering intraocular pressure. The micropulse mode provided a more consistent and predictable effect in lowering intraocular pressure with minimal ocular complications.

TL;DR: This document developed by the International Society for Clinical Electrophysiology of Vision provides an introduction to standard visual electrodiagnostic procedures in widespread use including the full-field electroretinogram (ERG), the pattern electroret inogram (pattern ERG or PERG), the multifocal electroretInogram (multifocal ERG) and the electrooculogram (EOG).
Abstract: Clinical electrophysiological testing of the visual system incorporates a range of noninvasive tests and provides an objective indication of function relating to different locations and cell types within the visual system. This document developed by the International Society for Clinical Electrophysiology of Vision provides an introduction to standard visual electrodiagnostic procedures in widespread use including the full-field electroretinogram (ERG), the pattern electroretinogram (pattern ERG or PERG), the multifocal electroretinogram (multifocal ERG or mfERG), the electrooculogram (EOG) and the cortical-derived visual evoked potential (VEP). The guideline outlines the basic principles of testing. Common clinical presentations and symptoms are described with illustrative examples and suggested investigation strategies.
