Tomography Data

Purpose. To assess the morphological parameters of the central retina in different groups with unblocked macular rupture after primary surgery for macular rupture (MR). Material and methods. This study involved 32 patients (35 eyes), including 19 women, 13 men. 3 groups were formed according to the principle of primary surgery. All patients underwent standard ophthalmological examinations, as well as optical coherence tomography (OCT). Results. According to OCT data, the morphological and functional parameters were different depending on the primary method of surgical treatment. The diameter of the MR along the large and small radius is the biggest in the 3rd group. The area of edema in the analysis of various methods of surgical treatment did not differ statistically. Conclusion. The functional parameters of the central part of the retina do not depend on the initial method of surgical intervention. The use of mechanical action on the retina causes rigidity of the edges of the macular rupture, and when using an introverted flap, the small and large diameters of the macular rupture remain minimal, in contrast to the use of platelet mass and mechanical closure of the MR. Key words: macular hole, platelet rich mass, introverted flap, mechanical closure, rigid.

Analysis Of Results

Purpose. Analysis of functional and anatomical results surgical treatment of retinal detachment and macular hole (RDMH) with internal limiting membrane (ILM) peeling and silicone tamponade. Material and methods. Analysis of results surgical treatment of 17 patients (17 eyes) with RDMH was carried out. Disease duration ranged from 2 weeks to 3 months. Visual acuity before surgical treatment ranged from no light perception to 0.05 (on average 0.01±0.02). All patients underwent endovitreal surgery with ILM removal. Then retinal holes were localized at periphery with further endolaser coagulation or cryocoagulation and silicone oil (5700 cSt) tamponade. Results. Retinal adhesion was noted in all eyes after primary surgery. Closure of hole was successful in 16 patients. After operation, visual acuity improved in all patients, averaging 0.11±0.09. Conclusion. Vitrectomy with IPM removal and silicone oil (5700 cSt) tamponade in treatment of RDMH made it possible to achieve reattachment of retina in 17 patients, complete closure of macular hole in 16 of 17 patients. One patient, according to optical coherence tomography, showed decrease diameter of macular hole after 12 months. Positive functional effect was achieved in increase visual acuity to average of 0.15±0.15 after 12 months. Key words: retinal detachment, macular hole, vitrectomy, internal limiting membrane removal, silicone oil tamponade, visometry, optical coherence tomography.

Morphofunctional Analysis

Purpose. To evaluate the role of microperimetry and optical coherence tomography (OCT) in the morphofunctional analysis of the retina after surgical treatment of idiopathic macular holes (IMH). Materials and methods. A retrospective study of 33 patient's treatment results (33 eyes) with IMH was carried out. All patients underwent minimally invasive with 25G or 27G vitrectomy. Best corrected visual acuity (BCVA), macular photosensitivity, fixation stability, macular neuroepithelial (NE) volume and minimal macular hole diameter were analyzed. Follow-up period: 6 months. Results. A complete closure of the macular hole was achieved in all cases post-op. The patients had reliable improvement of BCVA, retinal photosensitivity and decrease of macular NE volume. Based on a multifactor correlation analysis with the purpose to predict the results of surgical treatment, the dependence of post-op BCVA on the pre-op photosensitivity of the retina and the minimal diameter of the macular hole was revealed. Conclusions. Microperimetry and OCT are modern non-invasive research methods allowing to estimate anatomical and functional results of surgical IMH treatment. The study of retinal photosensitivity in the macula and minimal macular hole diameter pre-op allows to predict post-op BCVA, which has a practical importance. Keywords: idiopathic macular hole, vitrectomy, microperimetry, optical coherence tomography.
