Purpose. To compare the intraocular pressure (IOP) before and after Laser In Situ Keratomileusis (LASIK), measured by Diaton, Perkins, and noncontact air pulse tonometers.Methods. Fifty-seven patients with a mean age of 34.88 were scheduled for myopia LASIK treatment. Spherical equivalent refraction (SER), corneal curvature (K), and central corneal thickness (CCT) and superior corneal thickness (SCT) were obtained before and after LASIK surgery. IOP values before and after surgery were measured using Diaton, Perkins, and noncontact air pulse tonometers.Results. The IOP values before and after LASIK surgery using Perkins tonometer and air tonometers were statistically significant (p<0.05). However, no significant differences were found (p>0.05) for IOP values measured with Diaton tonometer. CCT decreases significantly after surgery (p<0.05) but no statistical differences were found in SCT (p=0.08). Correlations between pre- and postsurgery were found for all tonometers used, withp=0.001andr=0.434for the air pulse tonometer,p=0.008andr=0.355for Perkins, andp<0.001andr=0.637for Diaton.Conclusion. Transpalpebral tonometry may be useful for measuring postsurgery IOP after myopic LASIK ablation because this technique is not influenced by the treatment.

Purpose: to evaluate the safety and convenience of self-using the intraocular pressure tonometer TVGD-02 at home with no participation of medical professionals. Material and methods. 42 people formed 30 pairs: a patient and an assistant. In 9 pairs, each person played both roles. The participants practiced the technique of transpalpebral measurement of intraocular pressure (IOP) at home, and, as assistants, measured IOP of their partner patients. All subjects were asked to fill in a questionnaire to evaluate the convenience and safety of the tonometer use by a 5-point system. Results. The assistant users, aged 22 to 83 (ave. 59.68 ± 17.20 years) had diverse educational levels. Of the patient users, aged 22 to 82 (ave. 60.64 ± 17.10 years), 82.14 % had ocular pathology, while 35.7 % had glaucoma with concomitant pathology. In 100 % of cases, the participants required no professional assistance to properly prepare the tonometer for operation and perform IOP measurement. The accuracy and reproducibility of measurement results significantly increased with the assistants’ gaining skills of operating the tonometer. On the 1st day, the data obtained in a series of measurements scattered for the control block within 2.07 ± 1.70 [7; 0] mm Hg, while the measured IOP of the patient scattered within 2.89 ± 19.10 [8; 0]. In contrast, on the 5th day, measurement accuracy increased significantly and the scatter dropped to 1.21 ± 0.72 [2; 0] and 0.85 ± 0.69 [2; 0] mm Hg, respectively. The users rated the ease of using the device at different staged from 4.21 ± 0.67 to 5.0 ± 0.0 points. Conclusion. Assisted transpalpebral tonometry with the TVGD-02 tonometer ensures an adequate assessment of IOP in patients at home. The principles of device operation and the technique can be learned and skills can be gained without the participation of medical personnel.

Aim: to assess the efficacy and safety of EASYTON transpalpebral intraocular pressure (IOP) tonometer in the early postoperative period after penetrating keratoplasty (PK).Patients and Methods: 43 patients after unilateral PK were enrolled. IOP measurements with palpation and EASYTON transpalpebral IOP tonometer in the operated eye were performed daily for 7 days. In addition, IOP measurements with palpation, EASYTON, and the Goldmann applanation tonometer (GAT) in the fellow (non-operated) eye were performed.Results: Bland-Altman plots demonstrated a rather high degree of the similarity of IOP measurements with palpation, GAT, and EASYTON in the non-operated eyes. Therefore, IOP measurement by palpation is a rather informative technique and can be used to compare the accuracy of EASYTON in the operated eyes of the same patients. During the second step, a high degree of the similarity of IOP measurements with palpation and EASYTON was demonstrated in the operated eyes after PK. Mean IOP spread (as demonstrated by three consecutive IOP measurements with EASYTON) was 1.32 mm Hg thus showing a high degree of repeatability. The lack of the negative effects of IOP measurements with EASYTON supports its safety.Conclusion: EASYTON transpalpebral IOP tonometer prevents the subjectivity of IOP measurements after PK and makes tonometry available to the general public. The lack of the contact with the cornea, a rather high accuracy, a high repeatability, and the lack of negative effects allow for using this device after PK.Keywords: transpalpebral IOP tonometer, intraocular pressure, penetrating keratoplasty, instrumental tonometry, EASYTON, non-contact tonometry.For citation: Karlova E.V., Zolotarev A.V., Milyudin E.S., Pershakova A.E.

Introduction. Glaucoma is one of the most significant eye diseases. It is often diagnosed, not always amenable to therapy, and can lead to a complete loss of visual functions. In recent years, the method of osteopathic correction has become widespread as one of the effective methods of treatment and rehabilitation of patients with pathologies of various body systems. In the pathogenesis of glaucoma, it is customary to distinguish a dystrophic concept, which considers primary open-angle glaucoma as a result of dystrophic changes in the connective tissue, as well as in the endothelial lining of the trabeculae and Schlemm′s canal, especially destructive changes in mitochondria and the alteration of their functional activity. A vascular concept is also distinguished. According to this concept, the central link in the pathogenesis of glaucoma is circulatory disorder in the ciliary vessels, ocular artery, and major vessels of the head and neck, it can be assumed that osteopathic correction in the treatment of patients with open-angle glaucoma will be pathogenetically substantiated and will have a positive effect on intraocular pressure and trophicity of the optic nerve. The goal of research — to study the influence of in osteopathic correction on the nature of unoperated glaucoma (stage IIA) and to substantiate the possibility of using osteopathic correction in the complex treatment of patients with this pathology.Materials and methods. A prospective controlled randomized study was conducted at 52 city polyclinics, branch 3, Moscow, from January 2018 to January 2019. 40 patients (70 eyes) aged 50 to 75 years with primary open-angle glaucoma IIA stage were examined. At this stage of the disease, patients most often seek medical care and the issue of conservative management is primarily considered. All patients were divided into two groups of 20 people: the main group and the control group. The treatment in the main group included hypotensive drug therapy and osteopathic correction. Patients of the control group received only drug therapy. All patients underwent ophthalmic (visometry, tonometry, perimetry) and osteopathic examination twice: before the treatment and after 3 months.Results. For patients with primary open-angle IIA non-operated glaucoma, regional (most often regions of the head, neck, dura mater) and local (abdominal diaphragm, iliac bones, hip and knee joints) somatic dysfunctions were the most typical. In the main group a statistically significant decrease in the frequency and severity of dysfunctions at all levels was stated. Also, in patients receiving osteopathic correction, a significant decrease in the level of intraocular pressure and perimetric indices was noted. In patients of the control group, no reliable changes in these indicators were obtained.Conclusion. The results obtained indicate that osteopathic correction is clinically effective in the complex treatment of patients with primary open-angle II A glaucoma.

A case report on a 49-year-old female with diagnoses of ocular hypertension in her left eye (LE) treated with 250 mg/day acetazolamide for 2 years. During the slit-lamp examination, complete occlusion of both iridocorneal angles was detected. Intraocular pressure (IOP) was 10 and 35 mmHg in the right eye and LE, respectively. Phacotrabeculectomy was performed in the LE. After 1 month of the procedure, the patient developed a slowly progressive miopization from −1 to −3 diopters (D) the following months. Approximately 3 months after surgery, the patient developed an episode of acute pain, athalamia, and IOP 45 mmHg in her LE. Late-onset malignant glaucoma was suspected and the patient was treated with topical hypotensive and cycloplegic agent until a prompt vitrectomy was performed. Deepening of the anterior chamber and restoration of IOP to normal range was obtained after surgery.

Objective: The objective of the study was to compare the posture-induced intraocular pressure (IOP) changes in primary angle-closure glaucoma (PACG) with or without glaucoma medications, and healthy control eyes with normal IOPs in Indian subjects. Materials and Methods: The IOP was measured in the sitting position and the supine position after 10, 20, and 30 min with a rebound tonometer. Results: Twenty-five patients with PACG and 30 controls with normal IOPs were studied. The IOP in the sitting position measured with the rebound tonometer was 13.8 + 3.2 mm Hg in eyes with PAC, and 12.9 + 2.9 mm Hg in eyes with normal IOPs. The IOP increased to 14.4 mm Hg, 16.8 mm Hg, and 18.9 mm Hg at 10 min, 20 min, and 30 min in PACG subjects. In normal age-matched controls, the IOP increased to 13.4 mm Hg, 14.9 mm Hg, and 17.8 mm Hg at 10 min, 20 min, and 30 min, respectively, but none of these differences were significant (P = 0.09; P = 0.08, P = 0.08). The mean postural IOP change from baseline was also not significant between the two groups. Only three patients were on single antiglaucoma medication with well-controlled IOP in the PACG group. Conclusions: Postural IOP changes are comparable among eyes with PACG with and without glaucoma medications, and control eyes.
