Abstract Details

Purpose:

Pseudoexfoliative syndrome (PES) is one of the most common reasons of open-angle glaucoma development. Disorders of intraocular liquid flow and its slowing are the main reason of the IOP growing and glaucoma development. PES can be a marker of these disorders.

Setting:

We assessed the anterior segment of the eye and optical density of intraocular liquid in UV spectrum with wavelength 202 nm in Clinic "Visisobood-Plus", Kyiv, Institute of Physical Chemistry of L.B. Pisargevskiy NAS Ukraine, Kyiv

Methods:

All patients have been operated by one surgeon in term from 04/04/2017 to 05/06/17. There were 3 groups of patients: 1st – patients with cataract and PES (27 eyes); 2nd – patient with cataract, PES and glaucoma (18 eyes); 3rd – only cataract patients (44 eyes). We measured parameters of the anterior segment of the eye (anterior chamber depth and crystal lens length) and made spectrographic analysis of the intraocular liquid.

Results:

In the first and second groups parameters of the anterior segment of the eye were similar – the anterior chamber depth was 2,9±0,37 and 3,09±0,24 accordingly; lens was 4,85±0,39 and 4,74±0,32 accordingly. In the third group anterior chamber was deeper (3,27±0,29) and lens was shorter (4,45±0,32). Optical density of intraocular liquid was similar in the first and the second groups – 0,542±0,092 and 0,576±0,14. In the third we had got significantly lower optical density of intraocular liquid – 0,433±0,06. If optical density is higher - proteins are more, viscosity and pressure of liquid are higher.

Conclusions:

Increasing of lens length and narrowing of the anterior chamber in patients with cataract and PES can lead to the changes of the chemical structure of intraocular liquid and as a result to the IOP increase. Early cataract extraction in the patients with PES can normalize parameters of the anterior segment of the eye and prevent glaucoma development.
