Abstract The senile cataract represents the blurring of the crystalline lens after the age of 65. It occurs due to metabolic changes in the crystalline lens which occur over the years. The only effective way to treat cataract is the surgical one. Pseudoexfoliation is an age related systemic disorder. PEX represents the accumulation fibrillar material in the extracellular matrix of the tissue. The most known ocular manifestation of the PEX are the collection at iris pupillary margin and anterior lens capsule. This accumulation is associated with many intraoperative and postoperative complications in patients scheduled for cataract surgery. The aim of the study was to investigate the prevalence of the surgical complications during phacoemulsfication in patients with PEX. The study included 91 patients scheduled for cataract surgery divided into two groups (PEX group 46, control group 45 patients). Poor intraoperative midryasis, zonular dehiscence, postoperative corneal edema, anterior chamber inflammation, elevated intraocular pressure and tear film instability had particularly higher rate of occurring in PEX group comparing to the control group (p<0.001). The highest mean value of intraocular pressure was observed in PEX group on the first postoperative day 25.6 ± 1.1 mmHg, while the best corrected visual acuity was measured in control group 0.71 ± 1.2 one month after phacoemulsification. Cataract surgery in patients with PEX carries great risk, but with adequate preoperative planning, the awareness of the potential complications, can provide safe and routine phacoemulification in these patients.

To date, cataract surgery development aims at minimizing surgical trauma in order to achieve a quicker rehabilitation. However, one of the severe complications of cataract surgery is increased intraocular pressure due to the inflammatory response, the so-called reactive syndrome that occurs in the early postoperative period. Aim of the study was to evaluate the efficacy of a fixed combination of bimatoprost and timolol (Ganfort) eye drops in prevention of ocular hypertension and corneal edema after ultrasonic phacoemulsification. Materials and methods. The study included 60 patients (60 eyes) with uncomplicated cataracts of varying maturity degree. All patients were divided into 2 groups. Patients in the main group (30 patients, 30 eyes, 20 female and 10 male) underwent pneumotonometry before surgery and received a single instillation of Ganfort, and pneumotonometry was performed again 30 minutes after instillation (before surgery), and then again after surgery. Patients in the control group (30 patients, 30 eyes, 19 female and 11 male) underwent pnemotonometry before and after surgery. Results. The postoperative period was similar in both groups. On the first day after surgery, mean intraocular pressure in patients of the main group was 12.9 mmHg while in the control group the mean intraocular pressure was 20.1 mmHg. In patients of the main group, intraocular pressure decreased by 1/3 with Ganfort therapy on the first day after surgery, and biomicroscopic corneal findings were less pronounced in the main group compared to the control group. Conclusion. The results of our study show that even uncomplicated cataract phacoemulsification with IOL implantation leads to a reactive postoperative increase of intraocular pressure from 17.5 to 20.1 mmHg. In our study, the use of Ganfort did not cause side effects or intolerability. Ganfort use may be considered as an effective prophylactics of ocular hypertension and corneal edema after ultrasonic phacoemulsification.

Purpose.To compare ocular rigidity (OR) and outflow facility (C) in patients with nonproliferative diabetic retinopathy (NPDR) and control subjects.Methods. Twenty-four patients with NPDR (NPDR group) and 24 controls (control group) undergoing cataract surgery were enrolled. NPDR group was further divided into patients with mild NPDR (NPDR1-group) and patients with moderate and/or severe NPDR (NPDR2-group). After cannulation of the anterior chamber, a computer-controlled device was used to infuse saline and increase the intraocular pressure (IOP) in a stepping procedure from 15 to 40 mmHg. Ocular rigidity and outflow facility coefficients were estimated from IOP and volume recordings.Results. Ocular rigidity was 0.0205 μL−1in NPDR group and 0.0202 μL−1in control group (P=0.942). In NPDR1-group, OR was 0.017 μL−1and in NPDR2-group it was 0.025μL−1(P=0.192). Outflow facility was 0.120 μL/min/mmHg in NPDR-group compared to 0.153 μL/min/mmHg in the control group at an IOP of 35 mmHg (P=0.151). There was no difference in C between NPDR1-group and NPDR2-group (P=0.709).Conclusions. No statistically significant differences in ocular rigidity and outflow facility could be documented between diabetic patients and controls. No difference in OR and C was detected between mild NPDR and severe NPDR.

Purpose. To investigate whether adding video assistance to traditional verbal informed consent advisement improved satisfaction among cataract surgery patients. Methods. This trial enrolled 80 Chinese patients with age-related cataracts scheduled to undergo unilateral phacoemulsification surgery. Patients were randomized into two groups: the video group watched video explaining cataract-related consent information and rewatched specific segments of the video at their own discretion, before receiving traditional verbal consent advisement; the control group did not watch the video. Outcomes included patient satisfaction, refusal to consent, time to complete the consent process, and comprehension measured by a ten-item questionnaire. Results. All 80 enrolled patients signed informed consent forms. Compared with the control group, members of the video group exhibited greater satisfaction (65% versus 86%, p=0.035) and required less time to complete the consent process (12.3±6.7 min versus 5.6±5.4 min, p<0.001), while also evincing levels of comprehension commensurate with those reported for patients who did not watch the video (accuracy rate, 77.5% versus 80.2%, p=0.386). Conclusion. The video-assisted informed consent process had a positive impact on patients’ cataract surgery experiences. Additional research is needed to optimize patients’ comprehension of the video.

Glycosaminoglycans are natural components of healthy joint cartilage and they also appear in healthy synovial fluid. An increased amount of glycosaminoglycans in synovial fluid is believed to be a marker of secondary osteoarthritis, regardless of its primary cause. The aim of our study was to define the relationship between glycosaminoglycans in the synovial fluid and joint disorders, age, and body weight. The samples of synovial fluid were obtained from dogs suffering from secondary secondary osteoarthritis (n = 35) and from control dogs (n = 18); control dogs had normal body weight. The results were compared among joints of dogs with secondary osteoarthritis divided into groups according to the criteria mentioned above and control dogs. Glycosaminoglycan concentrations in synovial fluid were measured using dimethylmethylene blue assay. The lowest mean value of glycosaminoglycans in synovial fluid was measured in the control group. Significantly higher glycosaminoglycan content (P < 0.05) was found in synovial fluid isolated from obese dogs compared to control dogs. Furthermore, we observed an age-related trend, in which the highest mean values were reached either in old dogs or pups. Despite the absence of significant differences in glycosaminoglycan values among dogs suffering from various types of secondary secondary osteoarthritis, the highest mean values were measured in fragmented coronoid processus group. Our data suggest that abnormally increased body weight has an impact on glycosaminoglycan concentration in synovial fluid which may imply faster degradation and turnover of joint cartilage. Such observation has not yet been published in veterinary medicine.

Aim. To assess the antioxidant capacity in patients with the «dry» form of age-related macular degeneration before and after combined treatment with polarized polychromatic non-coherent light and dynamic electromyostimulation. Methods. Two groups of patients with the «dry» form of age-related macular degeneration were examined. 40 patients (80 eyes) from the main group were treated using combined treatment and 39 patients (78 eyes) in the group of control who were treated conventionally. The integral blood antioxidant capacity was measured by galvanometry. Results. Blood antioxidant capacity in healthy subjects is 26.0 kC/l. In patients of the main group blood antioxidant capacity before the treatment was equal to 22.81±0.27 kC/l, compared to 22.17±0.20 kC/l in control group (total mean value 22.49±0.27 kC/l). There was a relevant elevation of the blood antioxidant capacity at the late stages after the treatment - up to 12 months, compared to only 2 months in the control group. Visual acuity in patients of the main group before the treatment was 0.87±0.02, after the treatment was finished - 0.96±0,01 (p 0.001), 2 months after the treatment - 0.95±0.01 (p 0.001), 6 months after the treatment - 0.96±0.01 (p 0.001), 12 months after the treatment - 0.95±0.01 (p 0.001). Visual acuity in patients of the control group before the treatment was 0.91±0.02, after the treatment was finished - 0.95±0.02 (p 0.05), 2 months after the treatment - 0.94±0.02 (p 0.05), 6 months after the treatment - 0.92±0.02 (p 0.05). 12 months after the treatment the visual acuity deteriorated compared to the treatment start and was measured as 0.89±0.02. Conclusion. There is a decrease of blood antioxidant capacity (22.49±0.27 kC/l) in patients with the «dry» form of age-related macular degeneration; a relevant increase of blood antioxidant capacity and visual acuity can be observed up to 12 months after the treatment with polarized polychromatic non-coherent light and dynamic electromyostimulation.

Purpose: To determine the preoperative visual acuity of cataract patients over a 10-year period in a tertiary facility as a means of auditing the cataract surgical services. Methods: A retrospective study of patients with age-related cataracts who had cataract surgery performed between January 2007 and December 2016 at the University College Hospital, Ibadan. Systematic random sampling and probability proportionate to size were used to recruit a representative sample. Information on sociodemographic characteristics, preoperative visual acuity, ocular and systemic comorbidities were retrieved and analysed. Results: Of the 499 patients studied, males were 268 (53.7%) and their mean age was 67.69 (±9.51) years. The predominant visual acuity was hand motion 184 (36.9%) and yearly mean preoperative visual acuity was in the range of 0.0037–0.04 decimal. Conclusion: The mean preoperative visual acuity of patients in this facility did not change over the 10-year study period. Mean value of preoperative visual acuity remained within the range of blindness and did not improve over the decade. This could either be a reflection of visual impairment at which our patients seek care or an indication of the range of visual acuities at which surgeons are willing to offer cataract surgery in our environment. This trend has negative implications on the burden of cataract blindness as it reflects poor coverage of surgery for other levels of visual impairment due to cataract.

Purpose. To analyze the patients with secondary dislocation of CTR and IOL within 5 years from cataract surgery, to determine predisposing factors.Methods. 16 eyes of 15 patients aged66.2±6.7(from 49 to 82) with CTR/IOL complex dislocation within 5 years from cataract surgery were compared with 26 patients aged67.1±7.2(from 53 to 85), implanted with CTR during cataract surgery to manage zonule dehiscence and did not dislocate for at least 5 years, in respect of cause, axial length and IOL power, refraction, coexistent pathology, and trauma.Results. Axial length of the eyeball was23.8±1.3(from 21 to 29) in the group of patients with CTR/IOL dislocation and20.7±1.2(from 19 to 24) in patients with no dislocation present (p=0.008). Crystalline lens dislocation was diagnosed before surgery in 13 of 16 patients with CTR/IOL complex dislocation as opposed to 7 of 26 eyes in the control group (p=0.01). Pseudoexfoliation was present in 50% and 58% in both groups, respectively. Traumatic dislocation was present in 8 patients, none of them with CTR/IOL dislocation (p=0.04).Conclusion. Longer axial length may contribute to the failure of the CTR to prevent in-the-bag IOL dislocation. Traumatic dislocation appears to be well fixed with the CTR.
