New Treatment

Subthreshold Diode Micropulse (SDM) laser is a relatively new treatment modality that confers very little to no anatomical risk to the retina. However, its efficacy is still being studied, and the scenario where SDM is most useful is still being elucidated. This paper reviews articles from 1997 to 2017 and reviews the settings, results, and outcomes of SDM in various clinical settings including diabetic macular edema, branch retinal vein occlusion, central serous Chorioretinopathy, proliferative diabetic retinopathy, and age-related macular degeneration.

Tractional retinal detachment is an uncommon complication of intravitreal anti-vascular endothelial growth factor (VEGF) injection wherein the drug triggers tractional retinal detachment as a result of fibrovascular membrane contraction. We present a case of a 42-year-old hypertensive woman diagnosed with chronic central retinal vein occlusion on both eyes. The right eye had total retinal detachment and neovascular glaucoma, while the left eye had retinal neovascularisation. Panretinal photocoagulation and intravitreal anti-VEGF injection was started on the left eye. However, she was lost to follow-up. She returned 4 months later with extensive tractional retinal detachment involving the macula on the left eye. She subsequently underwent vitrectomy with endolaser and silicone oil tamponade on the left eye. The anti-VEGF ‘crunch’ results from regression of fibrovascular proliferation with a concurrent increase in fibrosis, resulting in worsening retinal traction. With the widespread use of anti-VEGF agents, ophthalmologists need to be aware of this vision-threatening complication.

The chapter begins by discussing key clinical skills, namely fundus fluorescein angiography, abnormal fluorescein angiography, indocyanine green angiography, and electrophysiology. The following areas of clinical knowledge are then discussed: diabetic retinopathy, hypertensive retinopathy, retinal vein occlusion, retinal artery occlusions, age-related macular degeneration, intravitreal anti-VEGF injections, central serous chorioretinopathy, retinal vascular anomalies, retinal dystrophies, and choroidal dystrophies. The chapter concludes with eight case-based discussions, on gradual visual loss, central visual loss, visual loss in a hypertensive patient, sudden, painless visual loss, diabetic retinopathy, difficult night vision, visual loss in child, and macular lesion.

A cross-sectional, population-based, epidemiological study of blindness and visual impairment was conducted to evaluate the prevalence of vision loss and various sight-threatening conditions in the Lower Tugela health district of the KwaZulu-Natal province, South Africa. This study was conducted on a randomly selected sample of 3444 individuals from the district. This number represented 84% of those who were visited and 80.1% of the total sample selected. The participants ranged in age from 5 to 93 years (mean of 29.2 years and a median of 20.0 years). The proportion of men to women differed between participants aged <30 years and those aged >30 years. In both age groups, women represented the majority of participants (66.5%), but the number of women to men in the older age group was approximately twice that found in the group aged less than 30 years. The difference in age between the men and women in the study was not statistically significant (p >0.5). The study revealed that 6.4% of the population studied were visually impaired. The distribution of uncorrected visual acuity was better for women than for men for both OD and OS (p = 0.000 for OD and OS). The main causes of visual impairment were refractive error (44.5%), cataract (31.2%), glaucoma (6.0%), hypertensive retinopathy (4.1%) and diabetic retinopathy (4.1%). Unilateral blindness (OD) was present in 0.78% (95% Confidence interval (CI): 0.42%-1.14%) of participants and unilateral blindness (OS) was present in 1.1% (95% CI: 0.70%-1.50%). Thirty-one participants (0.9%) were bilaterally blind with the main causes being cataracts (54.8%) and refractive error (12.9%). Glaucoma and hypertensive retinopathy were responsible for 6.4% of ..bilateral blindness. Diabetic retinopathy, other retinal conditions (coloboma) and corneal scarring were each responsible for 3.2% of bilateral blindness. Albinism, coloboma and age-related macular degeneration accounted for 9.7% of bilateral blindness. The data provides much needed information to support the planning of eye care programs in KwaZulu-Natal.  (S Afr Optom 2013 72(3) 110-118)
