RESUMO

AIM: To assess the necessity of neuroimaging in patients with neurological or atypical findings of normal tension glaucoma (NTG) who do not exhibit typical glaucoma manifestations. METHODS: A retrospective analysis was conducted on 90 atypical NTG patients who underwent cranial magnetic resonance imaging (MRI) due to atypical symptoms. The demographic characteristics, clinical parameters, and radiological findings were recorded. RESULTS: Among the patients, 66.7% had abnormal radiology results, with the most common findings being gliosis (34.4%), sequelae of cerebrovascular events and vascular malformations (14.4%), and benign intracranial mass lesions (11%). Non-glaucomatous visual field defects were more frequently observed in patients with abnormal neuroimaging results. However, there were no significant differences in intraocular pressure, optic disc parameters, retinal nerve fiber layer thickness, and visual field indices between patients with normal and abnormal radiological results. The mean age of the patients was 58.74y. Interestingly, there was a significant age difference, with the abnormal radiology group having a higher median age (P=0.021). CONCLUSION: The study highlights the importance of cranial imaging in older NTG patients to detect underlying pathologies and prevent misdiagnosis. It suggests that neuroimaging may be warranted in NTG patients with atypical visual field defects incompatible with glaucoma. However, routine neuroimaging in all NTG patients without classic neurological signs may not be necessary.

RESUMO

Objectives: To compare the optical disc and macular vascular density values of patients with glaucoma and healthy individuals by using optical coherence tomography angiography and evaluate the relationship between structural and functional test results and vascular density. Materials and Methods: The study included 128 eyes in total: 31 with pseudoexfoliation glaucoma (PEG), 55 with primary open-angle glaucoma (POAG) and similar visual field defects, and 42 healthy eyes. Whole image peripapillary vessel density (wpVD), intradisc vessel density (idVD), peripapillary vessel density (pVD), whole image macular vessel density (wmVD), and parafoveal vessel density (pfVD) values were compared between the groups. Correlations between visual field findings, retinal nerve fiber layer (RNFL) and optic nerve head measurements and peripapillary and macular vascular density were analyzed. Results: In the PEG and POAG groups, wpVD, idVD, wmVD, and pfVD values were significantly lower in than the control group. In the PEG group, wpVD was found to be significantly lower than the POAG group (p<0.001). There was no significant difference between the PEG and POAG groups in wmVD and pfVD except for nasal pfVD. There were strong positive correlations between RNFL thickness and pVD in the glaucoma groups (p<0.001). Significant correlations were found between visual field mean deviation and pattern standard deviation values and peripapillary and macular vessel density values in the glaucoma groups. Conclusion: Vascular density values were lower in glaucoma patients compared to normal individuals, and there is a strong correlation between structural and functional tests and vessel density values. The lower vascular density in the PEG group compared to the POAG group indicates that vascular damage may be more common in PEG patients.

RESUMO

PURPOSE: To present the outcomes and factors affecting the success of trabeculectomy performed as the first surgery in primary pediatric glaucoma. METHODS: Pediatric patients with primary glaucoma who underwent trabeculectomy as the first surgery were retrospectively reviewed. Age, gender, preoperative intraocular pressure (IOP), operation age, axial length, corneal diameter, anterior segment findings, antimetabolite used, complications, and 1-month, 3-months, 1-year, and most recent postoperative findings were recorded. Postoperative IOP with/without medication of 18 mmHg or less was considered successful. Factors that may have affected surgical success were also evaluated using multivariate analysis. RESULTS: Included in the study were 48 patients, of whom 30 had primary congenital glaucoma and 18 had juvenile glaucoma. The mean preoperative IOP was 36.84 ± 6.30 mmHg, and the mean follow-up time was 7.95 ± 6.93 years. The median operation age value was 100.00 ± 100.83 (median: 60; IQR: 153) months. The postoperative IOP at the 1-month, 3-months, 1-year, and most recent follow-ups were 15.39 ± 6.88, 15.70 ± 7.36, 16.28 ± 7.86, and 17.48 ± 8.44 mmHg, respectively (p = 0.565). While there were no postoperative complications in 24 of the patients (50.0%), the most common complications were choroidal detachment and hypotony. Postoperative complication development was found to be significant as a factor affecting surgical success in the multivariate logistic regression analysis. Surgical success rates for all of the patients were 71.7%, 65.9%, 65.0%, and 61.4% at the 1-month, 3-months, 1-year, and most recent follow-ups, respectively. A significant difference was found between the congenital and juvenile groups in terms of surgical success only at 3 months (p = 0.953, p = 0.042, p = 0.191, p = 0.218; respectively). DISCUSSION/CONCLUSION: The fact that surgical success was partially higher in the juvenile group confirmed the idea that the results of trabeculectomy will be more favorable in patients of older age and without anterior segment anomalies.

RESUMO

PURPOSE: To assess the risk factors associated with the development of hypotony after Ahmed glaucoma valve (AGV) implantation. METHODS: One hundred and ninety-three eyes of 177 patients with various types of glaucoma that were treated with AGV implantation were retrospectively evaluated. Intraocular pressure lower than 6 mmHg related to the surgery is defined as postoperative hypotony. Patients' demographic characteristics, type of glaucoma, preoperative and postoperative visual acuity, necessity of antiglaucoma treatments, lens status, previous ocular surgeries, intraocular pressure (IOP) measurements before and after surgeries, the need for additional procedures and postoperative complications were recorded from the patients' charts. RESULTS: Hypotony was seen in 68 of 193 eyes (35.2%) postoperatively. In 45 eyes (23.3%), it has occurred in first postoperative day and in 23 eyes (11.9%) after the first day within the first week. There was no difference in intraocular pressures between two groups in the first year follow-up. Pre- and postoperative best-corrected visual acuities, age and gender were not statistically different between hypotony and no hypotony groups (p > 0.05). Also, lens status, history of previous ocular surgery, type of glaucoma and number of preoperative glaucoma medication usage were not found to be different between groups (p > 0.05). CONCLUSIONS: Potential risk factors such as age, sex, lens status, history of previous ocular surgeries, preoperative glaucoma medication usage or glaucoma type are not found to influence upon postoperative hypotony prevalence for AGV surgery. Surgery type and personal ocular factors, which could not be determined beforehand, could be more important than demographic features.

RESUMO

OBJECTIVES: This study examined the effect of antiglaucomatous drops with different preservatives on corneal biomechanics using the ocular response analyzer (ORA) (Reichert Technologies, Inc., Depew, NY, USA). METHODS: Patients using antiglaucomatous medical treatment containing a single agent combined with a preservative for at least 1 year who underwent a control examination between January and December 2017 at a glaucoma unit were included in this retrospective study. The patients were divided into 5 groups according to the antiglaucomatous agent and preservative ingredients. Measurements were taken with the ORA and compared with a control group. RESULTS: A total of 83 eyes treated eyes were included and analyzed. Thirty-three eyes of 33 patients were treated with latanoprost+benzalkonium chloride (BAC), 17 eyes of 17 patients were treated with travoprost+polyquad, 7 eyes of 7 patients were treated with bimatoprost+BAC, 18 eyes of 18 patients were treated with brimonidine+purite, 8 eyes of 8 patients were treated with brimonidine+BAC. A control group of 23 eyes of 23 healthy patients was also assessed for comparison. A significant decrease in corneal hysteresis (CH) and corneal resistance factor (CRF) was seen in the patients using bimatoprost+BAC and brimonidine+BAC when compared with the control group. Evaluation of the bimatoprost+BAC group and the latanoprost+BAC group revealed that the CH and the CRF was significantly lower in the group using bimatoprost+BAC (p<0.01). CONCLUSION: It has been reported that CH is a more important prognostic marker than central corneal thickness in glaucoma patients. Loss of visual field progresses faster in eyes with a low CH. Both preservatives and the active antiglaucomatous agents in medications can affect CH. Variation in CH in patients using antiglaucomatous drops over a long period is important in both the progression and follow-up of the disease.

RESUMO

PURPOSE: To evaluate alterations in corneal biomechanical properties before and 6 months after conventional trabeculectomy (TRAB) and Ahmed glaucoma valve (AGV) implantation. METHODS: Thirty-nine eyes of 39 patients were evaluated retrospectively. Complete ophthalmological examinations including evaluation of corneal biomechanical properties using the Ocular Response Analyzer were performed before and after 6 months postoperatively. A mean of four measurements for corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann correlated intraocular pressure (IOPg), and corneal compensated intraocular pressure (IOPcc) was recorded. The participants had undergone trabeculectomy or shunt surgery as the first surgical procedure for glaucoma treatment of uncontrolled IOP with maximum antiglaucoma eyedrops. RESULTS: There were 20 eyes of 20 patients in trabeculectomy group and 19 eyes of 19 patients in AGV implantation group. There was no significant difference between two groups in terms of sex, age, eye laterality, lens status, antiglaucoma drug usage, preoperatively measured Mean Deviation of Humphrey Visual Field Analyzer, CH, CRF, IOPcc, and IOPg (p > 0.05). CH and CRF increased significantly after shunt surgery (p < 0.001). CH increased in trabeculectomy group postoperatively (p < 0.001); however, CRF showed a small amount of decrease, but this reduction was not statistically significant (p > 0.05). CH and CRF showed higher increase after AGV surgery than trabeculectomy surgery (p < 0.05). There was no significant correlation between IOP changes and CH-CRF changes in both TRAB and AGV groups (p > 0.05). CONCLUSION: According to our results, surgical technique differences may have an impact on postoperative corneal biomechanical outcomes. AGV surgery offers better corneal biomechanical results than standard trabeculectomy in 6-month follow-up.

RESUMO

Objectives: To report the results obtained from glaucoma drainage device (GDD) implantation in patients with aniridia-related glaucoma and to review the literature. Materials and Methods: We retrospectively reviewed 6 patients who underwent GDD implantation for glaucoma secondary to congenital aniridia between April 2001 and February 2015. Data on age at surgery, gender, laterality, surgeries before GDD implantation, GDD model, concomitant ocular disorders, visual acuity, and intraocular pressure (IOP) values before and at 1 and 12 months after GDD implantation, medications, follow-up period, findings during last visit, complications, and course of disease were collected. Results: Mean age at surgery was 16.00±12.31 years (range 5-37 years). Mean IOP was 33.00±12.11 (range 22-50) mmHg just before the GDD implantation with a mean of 3.5±1.2 medications. Mean IOP 1 month after implantation was 16.33±4.22 (range 12-24) mmHg with a mean of 1.5±0.8 medications; at 12 months, mean IOP was 19.50±4.76 (range 15-26) mmHg with 3.0±0.8 medications. At the last follow-up visit, IOP was 21.16±4.07 (range 16-26) mmHg with a mean of 3.33±0.51 medications. Mean follow-up was 19.16±8.8 (range 12-36) months. Surgical success rates were 83.3%, 66.6%, and 50.0% at 1 month, 12 months, and the last visit, respectively. Conclusion: GDD implantation was effective in controlling aniridic glaucoma with a success rate of 83.3% at 1-month follow-up and 66.6% at 1-year follow-up. Therefore, it should be considered as an initial surgical treatment for aniridic glaucoma; the clinician should be alert for concomitant ocular disorders.

RESUMO

PURPOSE: To assess and compare the outcomes of trabeculectomy with and without antimetabolites (AMs) and glaucoma drainage devices (GDDs) in the management of elevated intraocular pressure (IOP) after penetrating keratoplasty (PK). METHODS: Data of 84 eyes of 81 patients who underwent trabeculectomy (12 eyes without an AM and 42 eyes with an AM) or GDD implantation (30 eyes) after PK were reviewed retrospectively. The main outcome measures were IOP control, corneal graft survival, and postoperative ocular complications. RESULTS: At the final visit, IOP success (<22 mm Hg) was 58.3% in trabeculectomy alone, 64.3% in trabeculectomy with an AM (TrabAM), and 86.7% in GDD groups (P = 0.047). The median time from surgery to IOP failure was 1 month after trabeculectomy alone, 13 months after TrabAM, and 20 months after GDD implantation (P = 0.042). The cumulative probability of IOP success rates at 1 and 3 years postoperatively was as follows: 66.7% and 57.1% in trabeculectomy alone, 80.6% and 64.8% in TrabAM, and 92.3% and 84.6 in GDD groups (P = 0.063). The cumulative probability of corneal graft survival rates at 1 and 3 years postoperatively was as follows: 70.0% and 60.0% in trabeculectomy alone, 76.7% and 67.7% in TrabAM, and 65.8% and 52.6% in GDD groups (P = 0.549). CONCLUSIONS: GDDs are more successful than trabeculectomy in controlling IOP in eyes that have undergone PK, but they tend to have low corneal graft survival rates. Trabeculectomy without an AM has limited success and may be considered in a limited number of patients with a low risk for bleb failure.

RESUMO

PURPOSE: To evaluate the outcomes of Ahmed glaucoma valve (AGV) in the management of elevated intraocular pressure (IOP) secondary to steroid use for macular edema in patients with retinitis pigmentosa (RP). METHODS: A total of nine eyes of five patients were evaluated retrospectively. Complete success was defined as IOP ≤ 21 mmHg without glaucoma medications, while qualified success was defined as IOP ≤ 21 mmHg with glaucoma medications. RESULTS: Mean age at surgery was 25.0 ± 8.3 years, and mean follow-up time was 38.4 ± 13.2 months. Mean IOP was 41.0 ± 8.3 mmHg preoperatively, 9.4 ± 3.5 mmHg at first week (p = 0.008), 13.1 ± 3.6 mmHg at first month (p = 0.008), 14.8 ± 4.1 mmHg at 6th month (p = 0.008), 11.7 ± 2.6 mmHg at 12th month (p = 0.008), 12.4 ± 2.9 mmHg at 24th month (p = 0.008), 12.6 ± 3.6 mmHg at 36th month (p = 0.043) and 12.8 ± 4.2 mmHg at 48th month (p = 0.068) postoperatively. The mean number of topical anti-glaucomatous medications decreased from 2.8 ± 0.4 preoperatively to 0.4 ± 0.9 postoperatively (p = 0.007). Complete success was obtained in 7 (77%) eyes, and qualified success in 2 (23%) eyes. No failure was detected. CONCLUSIONS: AGV implantation can be considered as an alternative and safe option in the management of resistant, elevated IOP secondary to steroid treatment for macular edema in patients with RP.

RESUMO

BACKGROUND: To evaluate the effects of tolterodine on anterior segment and choroidal thickness by using the Pentacam system and optical coherence tomography (OCT) (Pentacam). METHODS: A total of 122 eyes of 61 patients (34 female; 27 male) were included in the study. All patients underwent a regular ocular examination and intraocular pressure measurements before and after 3 months of antimuscarinic drug tolterodine treatment, in addition, pupil diameter, anterior chamber depth, anterior chamber volume, anterior chamber angle, and lens thickness were measured through Pentacam (Oculus Inc., Wetzlar, Germany) system. Measurements of choroidal thickness were performed by OCT (Spectralis®, Heidelberg Engineering, Heidelberg, Germany). RESULTS: The mean age was 58.4 ± 7.3 years and 56.5 ± 11.1 years for female and male patients. The mean intraocular pressure was 15.10 ± 2.75 mmHg before treatment and 15.18 ± 2.65 mmHg after treatment. Pupil diameters were 3.09 ± 0.48 mm before treatment and 3.12 ± 0.43 mm after treatment. Anterior chamber depth, before and after treatment were 2.68 ± 0.65 mm and 2.70 ± 0.61 mm. The mean value for subfoveal choroidal thickness was 267.92 ± 81.35 µm before the administration of tolterodine, whereas the mean choroidal thickness was 271.83 ± 75.42 µm after the administration of tolterodine. The alterations in the subfoveal choroidal thickness were not statistically significant (p = 0.862). CONCLUSIONS: After 3 months of therapy with tolterodine, there were no significant changes in anterior segment parameters and choroidal thickness.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the long-term outcome of Ahmed glaucoma valve (AGV) implant for elevated intraocular pressure (IOP) in pediatric patients with uveitis. DESIGN: This was a retrospective chart review. PARTICIPANTS: The study included 16 eyes (11 children) with uveitis. METHODS: Success was defined as having IOP between 6 and 21 mm Hg with (qualified success) or without (complete success) antiglaucoma medications and without the need for further glaucoma or tube extraction surgery. RESULTS: Mean age of patients at the time of AGV implantation was 14.19 ± 3.25 years. AGV implantation was the first glaucoma surgical procedure in 12 eyes (75%). Average postoperative follow-up period was 64.46 ± 33.56 months. Mean preoperative IOP was 33.50 ± 7.30 mm Hg versus 12.69 ± 3.20 mm Hg at the last follow-up visit (p < 0.001). Three eyes (18.7%) were determined as cases of "failure" because of tube removal in 2 eyes and a second AGV implantation in 1 eye. The cumulative probability of complete success was 68.8% at 6 months, 56.3% at 12 months, 49.2% at 36 months, 42.2% at 48 months, and 35.2% at 84 months, and the cumulative probability of eyes without complication was 75.0% at 6 months, 66.7% at 24 months, 58.3% at 36 months, 48.6% at 48 months and 24.3% at 108 months based on Kaplan-Meier survival analysis. CONCLUSIONS: Although AGV implant is an effective choice in the management of elevated IOP in pediatric uveitis, antiglaucoma medications are frequently needed for control of IOP. Tube exposure is an important complication in the long term. Differential diagnosis between relapse of uveitis and endophthalmitis is important in patients who received AGV implantation.

RESUMO

PURPOSE: To evaluate the agreement of corneal thickness (CT) measurements obtained by the Pentacam Scheimpflug camera, noncontact specular microscopy (SM), and ultrasonographic pachymetry (UP) in diabetic (DM) patients; and whether duration of diabetes and level of Hb A1c affect the agreement. MATERIALS AND METHODS: The CT was measured in 127 patients with DM, and 137 age and sex-matched healthy controls sequentially by Pentacam, SM, and UP. Also diabetic subjects were subdivided according to duration of diabetes and Hb A1c levels. Pearson correlation analysis, linear regression analysis, and Bland-Altman plots were used for examination of agreement. RESULTS: We found an excellent and statistically significant correlation of CT measurements between Pentacam-SM (R2 = 0.768; R2 = 0.855), Pentacam-UP (R2 = 0.546; R2 = 0.652), and SM-UP (R2 = 0.759; R2 = 0.797) in diabetic and control groups, respectively. We performed further comparisons of the pair of instruments using the Bland-Altman analysis, and the mean difference between pair of methods was much smaller for SM-UP pair (-4.20 ± 9.79 in diabetic, and -4.58 ± 8.08 in control group). The group having Hb A1c level less than 7.5% showed the best agreement between SM-UP pair as in the control group. Whereas Pentacam-UP showed the best agreement in the group having Hb A1c level ≥7.5%. The best agreement was between Pentacam-UP in 0-4 year group, and between Pentacam-SM in 5-9 year and ≥10 year groups. CONCLUSION: SM-UP pair showed a higher agreement in diabetic patients. According to subgroup analyses, Hb A1c level, rather than the duration of diabetes, may determine the agreement of these pachymetry devices. But the difference in CT measurements between devices can still influence clinical diagnosis and treatment. Therefore, these methods are not completely interchangeable.

RESUMO

INTRODUCTION: The choroid receives about 65-85% of ocular blood flow, which comes from the ophthalmic artery (OA), the first branch of the internal carotid artery (ICA). In the foveal avascular zone, there is no retinal vascular supply; therefore, choroidal blood supply plays a significant role in this subfoveal region. The ocular pulse amplitude (OPA) provides useful information about intraocular blood flow and is an indirect indicator of choroidal perfusion. In this study, we aimed to assess the correlation between the OPA, subfoveal choroidal thickness (CT), and ICA Doppler ultrasound findings in healthy eyes. METHODS: In total, 48 eyes of 48 healthy volunteers were included in this study. All eyes underwent detailed ophthalmic evaluation, including slit-lamp biomicroscopy, fundus examination, axial length, OPA measurements, and optical coherence tomography (OCT) with enhanced depth imaging mode. Carotid Doppler ultrasound examination was performed by the radiologist. The correlation between the OPA, subfoveal CT, and ICA Doppler findings [peak systolic velocity (PSV) and end-diastolic velocity (EDV)] were evaluated, considering gender and age. RESULTS: The mean OPA was 3.06 ± 1.34 mmHg. The mean subfoveal CT was 305.85 ± 33.98 µm. The mean PSV and EDV of ICA were 73.25 ± 23.63 cm/s and 26.93 ± 13.42 cm/s, respectively. A moderate positive correlation was found between OPA and subfoveal CT (p = 0.001; rho = 0.481). This relationship was present in both men and women. While a positive correlation was found between the OPA and subfoveal CT in subjects under the age of 50 years, there was no correlation in those over the age of 50 years. CONCLUSIONS: A fair correlation was found between the OPA and subfoveal CT in healthy subjects under the age of 50.

RESUMO

PURPOSE: To evaluate the long-term effect of oral isotretinoin therapy on macula ganglion cell complex (GCC) thickness by spectral domain optical coherence tomography (SD-OCT). MATERIALS AND METHODS: Newly diagnosed cystic acne patients who received low dose for a long time systemic isotretinoin therapy were included in this study. Thorough ophthalmic evaluation and GCC thickness analysis by using SD-OCT were performed at baseline, and at 1, 3, 6, and 12 months of treatment. RESULTS: Forty-eight eyes of 24 patients (15 females, 9 males) were included in the study. The mean age of patients was 19.37 ± 2.74 years (range 14-25 years). The full ophthalmologic examination was normal in all eyes before treatment. During the treatment there were no change in visual acuity, refractive error, intraocular pressure and tear break-up time. The mean GCC thicknesses were 81.45 ± 4.91, 81.45 ± 5.12, 81.81 ± 4.68, 81.87 ± 4.91 and 81.64 ± 5.09 µm at pretreatment and at 1, 3, 6, and 12 months of treatment, respectively (p = 0.803). CONCLUSION: One-year systemic use of isotretinoin had no significant effect on the thickness of macula ganglion cell. Macular ganglion cell analysis is useful for determining and following the toxic effects of systemic drugs on the retina. However, it is more rational to consider it as an adjunct to electrophysiological testing rather than used alone.

RESUMO

Central serous chorioretinopathy (CSCR) is characterized by neurosensory retinal detachment. Because the retina pigment epithelium and choroidal pathology is the current mechanism in CSCR, many studies in the literature focused on the outer retinal layers. There is little information about the functional or histological structure of the detached retina. In this study, we assess the ganglion cell complex (GCC) thickness using optical coherence tomography (OCT) in patients with acute and chronic CSCR. The medical records of 16 acute and 19 chronic CSCR patients which have no other disorders that cause a serous macula detachment were analyzed. Chronic cases were also divided into two subgroups: chronic active and chronic nonactive CSCR. The eyes with extramacular involvement or cystoid degeneration and cases which developed choroidal neovascularization were excluded from the study. The mean, minimum, superior-nasal, superior, superior-temporal, inferior-nasal, inferior, and inferior-temporal GCC values obtained using OCT were used for analysis. The duration from the onset was 7.8 ± 4.5 weeks and the mean age was 45.0 ± 10.7 years in acute CSCR, and in chronic cases the values were 36.0 ± 6.2 weeks and 52.9 ± 10.5 years, respectively. There were no significant differences in sex distribution. The chronic cases were statistically significantly older than acute cases (p = 0.02). While there was no difference between the acute and chronic cases, there were statistically significant differences between the chronic CSCR and control group in all values of GCC. Additionally, there were statistically significant differences between the acute CSCR and control group in mean, minimum, and superior-temporal GCC thicknesses. Although choroid and outer retinal layers play an important role in the pathogenesis of CSCR, there is scant information about the functional or histological structure of the detached retina in CSCR. Our results showed that GCC was significantly reduced in both acute and chronic CSCR compared to healthy subjects. Analysis of ganglion cell helps us understand the etiology of the patients which healed anatomically but had limited visual improvement in CSCR.

RESUMO

PURPOSE: To evaluate the changes in the macular ganglion cell complex (GCC) thickness and central macular thickness (CMT) as measured by spectral domain optical coherence tomography (OCT) post-argon laser panretinal photocoagulation (PRP). METHODS: The medical records of 25 patients with proliferative diabetic retinopathy (PDR) who underwent PRP, 29 patients with non-proliferative diabetic retinopathy (NPDR), and 29 patients with diabetes but without diabetic retinopathy (DR) were analyzed. The patients who received PRP were followed up for one year. The follow-up measurements were evaluated at baseline, and months 1, 6, and 12 post-argon laser PRP. The baseline values of CMT and GCC thickness were compared among the groups to assess changes with PRP therapy. RESULTS: The CMT gradually increased in months 1 and 6 and then decreased; however, it was significantly higher than the baseline value at month 12 in the PDR group post-PRP. The GCC thickness also increased at months 1 and 6 in almost all segments of the macula, but at month 12 decreased to the baseline value. There was no correlation between the increasing thickness of the macula and change in the GCC thickness post-PRP period in the PDR group. In addition, no significant correlation was detected between the GCC thickness and best-corrected visual acuity during all follow-up visits. CONCLUSIONS: GCC thickness increased significantly until month 6 compared with baseline values in most of the macular segments post-PRP in the PDR group. The GCC thickness at month 12 was not different from the baseline thickness in any of the macular segments.

RESUMO

PURPOSE: To evaluate short-term to long-term outcomes of Ahmed glaucoma valve (AGV) implantation in the management of uveitic glaucoma (UG) secondary to Behçet disease (BD). PATIENTS AND METHODS: A retrospective chart review of 47 eyes of 35 patients with UG secondary to BD who underwent AGV implantation was conducted. Success was defined as having an intraocular pressure (IOP) between 6 and 21 mm Hg with (qualified success) or without (complete success) antiglaucomatous medications and without need for further glaucoma surgery. RESULTS: Mean postoperative follow-up was 57.72±26.13 months. Mean preoperative IOP was 35.40±8.33 mm Hg versus 12.28±2.90 mm Hg at the last follow-up visit (P<0.001). Mean number of preoperative topical antiglaucomatous medications was 2.96±0.29 versus 0.68±1.12 at the last follow-up visit (P<0.001). In all eyes, IOP could be maintained between 6 and 21 mm Hg with or without antiglaucomatous medications during follow-up. The cumulative probability of complete success was 46.8% at 6 months, 40.4% at 12 months, and 35.9% at 36 months, and the cumulative probability of eyes without complication was 53.2% at 6 months, 46.5% at 12 months, and 39.6% at 24 months postoperatively based on Kaplan-Meier survival analysis. No persistent or irreparable complications were observed. CONCLUSIONS: This study includes one of the largest series of AGV implantation in the management of UG with the longest follow-up reported. AGV implantation can be considered as a primary surgical option in the management of UG secondary to BD with 100% total success rate (with or without medications).

RESUMO

BACKGROUND/AIM: The purpose of the present study was to evaluate clinical outcomes and optical performance of 4 different multifocal intraocular lenses (IOLs). MATERIALS AND METHODS: Ninety eyes of 51 patients who received Reviol MFM 611, Reviol MFM 625, Acri.LISA, and ReSTOR SN6AD3 multifocal IOLs after cataract surgery were retrospectively evaluated. The patients were similar in terms of age, sex, cataract hardness and axial length. The mean outcome measures were uncorrected and corrected distance visual acuity (UDVA, CDVA), distance-corrected intermediate and near visual acuity (DCIVA, DCNVA), intra or postoperative complications, and contrast sensitivity (CS) results under mesopic conditions. The mean follow up period was 10.5 months (range: 6-12 months). RESULTS: All cases were within ± 0.75 D of emmetropia. Postoperative increase in UDVA and DCNVA was statistically significant in all groups. The Acri.LISA group showed slightly lower DCIVA compared with the other IOLs. CS was clinically similar between the groups. None of the patients developed any early or late postoperative complication or neuroadaptation problem, which necessitated explantation of the lens. CONCLUSION: All four multifocal lens designs provided satisfactory visual functions and CS results in patients who fulfilled the criteria for multifocal lens implantation.
