Diabetic maculopathy (DM) is one of the major causes of vision impairment in individuals with diabetes. The traditional approach to diagnosis of DM includes fundus ophthalmoscopy and fluorescein angiography. Although very useful clinically, these methods do not contribute much to the evaluation of retinal morphology and its thickness profile. That is why a new technique called optical coherence tomography (OCT) was utilized to perform cross-sectional imaging of the retina. It facilitates measuring the macular thickening, quantification of diabetic macular oedema, and detecting vitreoretinal traction. Thus, OCT may assist in patient selection with DM who can benefit from treatment, identify what treatment is indicated, guide its implementing, and allow precise monitoring of treatment response. It seems to be the technique of choice for the early detection of macular oedema and for the followup of DM.

ABSTRACT.Purpose: To assess the possible association of lysyl oxidase-like 1 (LOXL1) gene variants with pseudoexfoliation syndrome (PEX) in Polish population. Methods: The group studied comprised of 36 patients with PEX (men and women) who presented to Department of Ophthalmology Collegium Medicum UMK in Bydgoszcz, Poland, and 30 control subjects. Blood samples were obtained from each patient via peripheral venipuncture, and genomic DNA was isolated according to the standard procedures. Three LOXL1 single nucleotide polymorphisms (SNPs) rs1048661 (R141L), rs3825942 (G153D) and rs216524 were genotyped in patient sample. Results: The significant association with PEX was found for the G allele of rs3825942 (p = 0.0047) and for the T allele of rs216541 (p = 0.021). The haplotype (GGT) consisting of all three risk alleles was significantly overrepresented (87.5%) in patients with PEX. Conclusion: Single nucleotide polymorphisms in LOXL1 are associated with PEX in Polish population which confirms the association previously reported for Icelandic, Swedish, Indian and other populations.

Even two years' follow-up is not sufficient to establish the total endothelial cell loss after cataract surgery. The amount of cell loss does not depend on the preoperative density.

PC IOL implantation in myopic eyes with cataract appears to be an efficacious, satisfactory and safe procedure.
