To determine the test-retest reliability of the Randot stereoacuity test when used as part of vision screening in schools. ⋯ Children exhibiting abnormal stereoacuity on initial testing are very likely to exhibit a normal result when retested. The value of a single, abnormal Randot graded-circles stereoacuity measure from school screening is therefore questionable.

To determine the effect of diabetes on inner and outer retinal function in persons with diabetes and no clinically detectable retinopathy or with non-proliferative diabetic retinopathy (NPDR). ⋯ Both inner retinal and outer retinal functions exhibited impairment related to NPDR. FDT perimetry and other visual function tests reveal an expanded range of diabetes induced retinal damage even in patients with good visual acuity.

Comparative Study
Outcomes of deep anterior lamellar keratoplasty following successful and failed 'big bubble'.
The most popular technique for deep anterior lamellar keratoplasty (DALK) is the 'big bubble' (BB) technique wherein air is injected in the cornea to create a bubble that separates Descemet's membrane (DM) from the stroma. An attempt to create a BB often results in the cornea being filled with numerous small bubbles without the formation of a BB. Manual dissection is then required to complete the procedure. The aim of the study is to compare these two groups, successful BB versus failed bubble (FB) dissection to determine whether the clinical outcomes were different. ⋯ In DALK, manual lamellar dissection is a reasonable alternative when BB separation of the DM is not achieved.

Bevacizumab for Coats' disease with exudative retinal detachment and risk of vitreoretinal traction.
To evaluate the effect of supplemental intravitreal bevacizumab for management of Coats' disease. ⋯ Coats' disease treated with intravitreal bevacizumab in addition to standard therapy can develop to vitreoretinal fibrosis and potentially traction retinal detachment. These tractional features are not often found in Coats' disease treated with standard measures without bevacizumab. Caution is advised in the use of bevacizumab for patients with Coats' disease.
