Study: High prevalence of diabetes in patients with type 2 macular telangiectasia in Puerto Rico

The cohort evaluated in the study showed a high prevalence of type 2 diabetes in patients with type 2 macular telangiectasia.

Macular telangiectasia is a disease that affects the macula, causing loss of central vision. It develops when there is a problem with the small blood vessels surrounding the fovea, the center of the macula, which gives us our sharpest central vision for activities such as reading.

There are two types of macular telangiectasia, and each affects the blood vessels differently.

In type 2 macular telangiectasia, the small blood vessels that surround the fovea become abnormal and may dilate (dilate). Type 2 affects both eyes, but not necessarily with equal severity.

Meanwhile, in type 1 macular telangiectasia, blood vessels dilate and form small aneurysms, which leak and cause swelling. This is called macular edema and it damages the macular cells. According to the American Academy of Ophthalmology, the disease almost always occurs in one eye.

For this reason, Puerto Rican health professionals undertook to describe the associations and clinical features of systemic diseases in the initial presentation of a group of patients with type 2 macular telangiectasia living in Puerto Rico.

Attached to the Medical Sciences Campus, the team conducted a retrospective review of patients with macular telangiectasia at four private retinal clinics in Puerto Rico. Demographic and clinical characteristics were recorded.

The study results detail that some 21 patients diagnosed with macular telangiectasia were included in the analysis. The mean age of presentation was 62 years. 86% were female and all patients were Hispanic.

In the sample, it was found that 71.4% of these patients had type II diabetes, 57.1% had hypertension and 42.9% had dyslipidemia. The most common ocular findings were the presence of vessels at right angles, 76.2% of eyes, and angiographic hyperfluorescence temporal to fovea, found in 52.4% of affected eyes. There was evidence of choroidal neovascularization in one eyeGives details of the study.

The cohort evaluated in the study showed a higher prevalence of type 2 diabetes in patients with type 2 macular telangiectasia compared to other patient cohorts, the authors say.

This also supports the findings of other studies showing that patients with macular telangiectasia are more likely to have type 2 diabetes and hyperlipidemia, although the study emphasizes that the prevalence of diabetes and hyperlipidemia may be due to selection bias. and more studies are needed to assess this. importance of these findings.
