Atrophy was frequently observed in patients with age-related macular degeneration and choroidal neovascular membranes undergoing anti-vascular endothelial growth factor therapy.

Very scarce data exist in the literature on the effect of ETS on diseases of the eye. It seems appropriate that ETS should be included in future studies addressing the effect of smoking on eye disease.

PurposeTo report anatomical and visual outcomes of Nd:YAG laser posterior hyaloidotomy (NYPH) in Saudi patients affected by Premacular subhyaloid haemorrhage (PMSHH).Methods8 eyes from 8 patients (7 males and one female) were treated with NYPH when no spontaneous resolution of PMSHH was noticed. The cause of PMSHH was proliferative diabetic retinopathy (PDR) in 3 cases, Central retinal vein occlusion (CRVO) in 2 cases, Valsalva retinopathy in 2 cases, and laser pointer injury in one case. The YAG laser was delivered using a Q switched mode and 3 mirrors contact lens. One attempt of laser delivery was enough in 6 cases and 2 cases needed 2 attempts. The laser power needed ranged between 2 and 4 mJ.ResultsAnatomical success was achieved in all cases. The mean LogMAR VA improved from 1.5 before treatment to 0.3 post-treatment. The difference is statistically significant (p = 0.012). No complications related to Nd:YAG laser therapy was reported in any of the study cases until the last follow up.ConclusionTo our knowledge, this is the first study to report the outcomes of NYPH for non-resolving PMSHH in Saudi cases. In this small cases series, the procedure seems to be safe, effective, simple, cheap, and non-invasive treatment modality for this disorder that is conducted in the outpatient setting. We think it should be considered as a first option for cases of SHH covering the fovea due to various aetiologies.
