RESUMEN
The article presents a clinical case of poppers-associated maculopathy - a maculopathy of toxic genesis, insufficiently represented in Russian scientific literature. The diagnosis was based on anamnestic data (long-term use of poppers), specific structural disorders of the outer layers of the retina in the foveolar zone according to spectral optical coherence tomography, as well as changes in multifocal and ganzfeld electroretinography readings. The main strategy for patients with this disorder is complete rejection of poppers.

The article presents a clinical case of a functioning hyaloid artery in a 69-year-old patient. The results of OCT-angiography made it possible to detect the presence of blood flow in the projection of the persistent hyaloid artery (PHA) on the cross-section and en-face images. The vascular bed of PHA spreading along the posterior surface of the lens in the form of separate branches was visualized by slit-lamp biomicroscopy. The uniqueness of this clinical case lies in the low probability of such findings in the elderly. The presence of a developing cataract indicates the need for an individual approach in determining treatment strategies. In our opinion, the consistent use of laser coagulation technologies and laser photodestruction of PHA will minimize the risk of hemophthalmos and tractional retinal detachment during the upcoming cataract surgery.

One of the directions of advancing phaco technology is related to adoption of hybrid phacoemulsification for clinical practice. Potential postsurgical changes in the macular area, when other factors are equal, can be seen as a conditional criterion for the injury rate of phaco surgeries. PURPOSE: To evaluate morphological and functional condition of the macular area after different types of phaco cataract surgeries. MATERIAL AND METHODS: Two groups were formed for comparative study in accordance with criteria for standardization and maximum mitigation of the impact of other factors on the condition of the retina - with standard ultrasound and hybrid (femtolaser-assisted) phacoemulsification (30 operations in each group). Examinations were performed initially, then 7-10 days, and 2-3 month after the surgery. Optical coherence tomography (OCT) and multifocal electroretinography (mfERG) were performed for evaluation of the morphological and functional condition of the macular area. RESULTS: There was no statistically significant dependence of linear and volumetric measures in the macular area on phaco surgery method, and the few variations were most likely related to increasing the time of ultrasound action in standard phacoemulsification. Revealed changes turned out to be significantly less marked than what is considered critical for development of macular edema. Improvement of baseline multifocal electroretinography measurements (increase of the density of retinal biopotential and decrease of latent time) just after the surgery results from the effect the lens opacification has on basic parameters, regardless of phacoemulsification technique. There were no significant differences in postsurgical measurements of multifocal electroretinography obtained in similar periods of postsurgical assessment after standard ultrasound and hybrid phacoemulsification. CONCLUSION: The results prove the safety of phaco surgery methods and the absence of negative impact of femtolaser component of hybrid phacoemulsification on structural and functional condition of central retina.

The review covers different aspects of the impact of femtosecond laser-assisted cataract surgery on the state of the macular zone of the retina. Literature search has revealed inconsistency of the published data and indicated the need for a more detailed study of this problem.
