ABSTRACT

BACKGROUND: This study reports the long-term visual and treatment outcomes in a whole-population, orthoptic-delivered pre-school visual screening (PSVS) programme in Scotland and further examines their associations with socioeconomic backgrounds and home circumstances. METHODS: Retrospective case review was conducted on 430 children who failed PSVS. Outcome measures included best corrected visual acuity (BCVA), severity of amblyopia (mild, moderate and severe), binocular vision (BV) (normal, poor and none), ophthalmic diagnosis and treatment modalities. Parameters at discharge were compared to those at baseline and were measured against the Scottish index of multiple deprivation (SIMD) and Health plan indicator (HPI), which are indices of deprivation and status of home circumstances. RESULTS: The proportion of children with amblyopia reduced from 92.3% (373/404) at baseline to 29.1% (106/364) at discharge (p < 0.001). Eighty percent (291/364) had good BV at discharge compared to 29.2% (118/404) at baseline (p < 0.001). Children from more socioeconomically deprived areas (OR 2.19, 95% CI 1.01-4.30, p = 0.003) or adverse family backgrounds (OR 3.94, 95% CI 1.99-7.74, p = 0.002) were more likely to attend poorly and/or become lost to follow-up. Children from worse home circumstances were five times more likely to have residual amblyopia (OR 5.37, 95% CI 3.29-10.07, p < 0.001) and three times more likely to have poor/no BV (OR 3.41, 95% CI 2.49-4.66, p < 0.001) than those from better home circumstances. CONCLUSIONS: Orthoptic-delivered PSVS is successful at screening and managing amblyopia. Children from homes requiring social care input are less likely to attend and are more likely to have poorer visual outcomes.

ABSTRACT

OBJECTIVE: To study the association between socioeconomic deprivation and prevalence of diabetic retinopathy (DR). DESIGN: Population-based, cross-sectional observational study and retrospective longitudinal analysis over 12 years. SETTING: Primary care, East of Scotland. METHODS: Outcome data from DR screening examinations (digital retinal photography) were collected from the Scottish regional diabetes electronic record from inception of database to December 2012. The overall Scottish Index of Multiple Deprivation (SIMD) 2012 score for each patient was obtained using their residential postcode. Multiple binary logistic regression was used to analyse the relationship between overall SIMD score and prevalence of DR, adjusting for other variables: age, gender, glycated haemoglobin, cholesterol levels and duration of disease. PRIMARY OUTCOME: Any retinopathy (R1 and above) in either eye. RESULTS: A total of 1861 patients with type 1 diabetes mellitus (DM) and 18,197 patients with type 2 DM were included in the study. Prevalence of DR in type 1 and type 2 DM were 56.3% and 25.5%, respectively. Increased prevalence of DR in type 1 DM was associated with higher overall SIMD score (p=0.002), with an OR for the most deprived relative to the least deprived of 2.40 (95% CI 1.36 to 4.27). In type 2 DM, the overall SIMD score was not significantly associated with increased prevalence of DR, with an OR for the most deprived relative to the least deprived of 0.85 (95% CI 0.71 to 1.02, p=0.07). CONCLUSIONS: Socioeconomic deprivation is associated with increased prevalence of DR in patients with type 1 DM and this occurs earlier. This highlights the need for targeted interventions to address inequalities in eye healthcare.

ABSTRACT

PURPOSE: To investigate the clinical features of all patients with acute-onset diplopia presenting to the ophthalmology department. METHODS: The notes of every patient who presented with acute onset (<4-week duration) diplopia to the ophthalmology clinic over a 2-year period were reviewed. Data regarding clinical features, underlying aetiology, past medical history, investigations and outcomes were extracted. RESULTS: One hundred and forty-nine patients presented with 53.7% having an isolated third, fourth or sixth nerve palsy, 10.7% a mechanical cause, 10.1% a dysfunction of higher control, 8.1% decompensation of a pre-existing heterophoria, 6.7% idiopathic, 5.4% causes of monocular diplopia and 5.3% another diagnosis. Neuroradiological investigation identified that <5% of patients had a serious underlying pathology, which required immediate management; 80.5% had a diagnosis and underlying aetiology, which were obvious at presentation based only on clinical information and evaluation. CONCLUSIONS: Acute onset diplopia is an uncommon and challenging presentation for the ophthalmologist to manage. These results demonstrate that the aetiology is commonly identifiable at the first presentation based on clinical evaluation, only a small percentage require urgent radiological investigation and a small minority of cases are likely to have serious emergent pathology.

ABSTRACT

PURPOSE: To collate information on patients registered blind secondary to glaucoma between 2000 and 2009 and compare findings to an identical study completed a decade earlier between 1990 and 1999. METHODS: The records of all people registered as blind via the Fife Society for the Blind between 2000 and 2009 were retrospectively examined and those with glaucoma as the primary cause were studied in detail. We compared these results with the results of our previous study, in which we examined the same documents for the preceding decade, 1990-1999. RESULTS: The glaucoma blind registration rate was reduced by 31% in the current study compared to the previous one (60 vs 87 patients, p = 0.013). At the same time, there was a 6% increase in blindness registrations due to all causes (881 vs 938, p = 0.62). Patients were referred with significantly fewer visual symptoms (33% vs 60%, p = 0.002) and glaucoma surgery rates increased from 44% to 62% in the current study (p = 0.013). In the later decade, more patients were offered partial sight registration before blind registration (37% vs 10%, p < 0.0001) and sustained independent living at the time of blind registration in this study (66% vs 33%, p < 0.0001). Nearly one-third of patients in the study group had cognitive impairment and/or hearing loss and this was similar to the first study. CONCLUSIONS: The study demonstrates a downward trend in the rates of blind registration due to glaucoma, compared to stable rates of registration for all diseases. Over the time period of the two studies there were refinements in the way glaucoma is managed medically by the hospital eye service and in the community, with a high level of input maintained from the local low vision service.

ABSTRACT

We report a case series of capsule contraction syndrome in 5 eyes of 4 patients and describe a previously unreported complication: full flexion of the haptics onto the anterior surface of the optic. Haptics have been reported to slide anterior to the optic while remaining in their original coronal plane. As surgeons move to the use of preloaded injectable IOLs, it is important to scrutinize haptic-optic junction design and IOL material in the light of this complication.
