Abstract Details

Purpose:

Develop a dynamic observation method for cataract progression

Setting:

The application of an objective method of quantifying the degree of lens haze in combination with functional techniques can objectify and mathematically describe the clinical picture of cataract, which is especially important in dynamic observation.

Methods:

In order to determine functional disorders, the patient is subjected to visometry according to Snellen 's method, Humphrey 's perimeter (HFA) according to the program in zone 30-2. The degree of opacities of the lens  is estimated in points according to the LOCS III system.The results of each examination are recorded in the patient 's map and compared with the previous one in the subsequent examination, the process dynamics being indicated by deviation of any of the indicators (Vis, MD, PSD, light sensitivity level at each field point, NO, NC, C, P) from the data obtained earlier.

Results:

According to the proposed method, examination of 312 eyes of patients with cataract of different maturity degree, at the age of 45 - 60 years. Surgical treatment is recommended by 30% of those examined, the rest received conservative therapy. During all term of observation (from 1 year to 3 years) at 38% of the patients receiving conservative treatment regress of functional violations for 11 - 25% from initial is revealed, at 32% of patients stabilization of functions was observed, regress of morphological changes is noted at 22%, and 34% during observation term had a stable condition of a crystalline lens.

Conclusions:

Thus morphological and functional disorders detected in the patient with cataract are described in digital equivalent, which significantly objectifies the clinical picture of the disease.Using the proposed modified method increased efficiency and objectivity of dynamic monitoring of cataract progression, simplified statistical analysis of obtained results. The method is technically simple, quickly feasible, non-invasive, does not require additional equipment, can be successfully used as screening for cataract detection and for dynamic monitoring of cataract progression.
