RESUMO
PURPOSE: To compare the visual and anatomic outcomes of intravitreal ranibizumab versus aflibercept in patients with diabetic macular edema (DME) in a real-world study. METHODS: This is a single-center retrospective comparative study of treatment-naïve patients who received intravitreal ranibizumab or aflibercept administration for DME for at least 12 months on an as needed regimen following three-monthly loading doses. The primary outcomes of the study were the mean change in best-corrected visual acuity (BCVA), central macular thickness (CMT), and central macular volume (CMV). Factors to potentially affect these parameters were also analyzed. RESULTS: A total of 100 eyes (66 patients) were included in the study. Fifty two eyes received ranibizumab and 48 eyes in aflibercept injections. At the end of follow-up, the improvement in mean BCVA was similar in both groups (p = 0.38). While the decrease in mean CMT at the 4th-month visit was significantly higher in the aflibercept-treated group than in the ranibizumab-treated group (p = 0.02), there was no difference between the two groups at the end of the 1-year follow-up (p = 0.25). There was no significant difference between the two groups in terms of change in mean CMV during the follow-up (p = 0.26, p = 0.27 at 4 and 12 months, respectively). The mean number of injections were also similar between groups (4.5 ± 1 vs. 4.6 ± 1.1 respectively, p = 0.63). CONCLUSION: In a real-world setting, ranibizumab and aflibercept were both found to be effective in the first-line treatment of DME. Patients with DME who received fewer injections in the real-world could achieve visual and anatomical results comparable to randomized controlled trials participants.

PURPOSE: To report the epidemiology, etiology, ocular characteristics, management, and visual outcomes of pediatric uveitis patients in Southern Turkey. METHODS: The clinical records of pediatric patients with a diagnosis of uveitis under the age of 16 years and followed up longer than 6 months were analyzed retrospectively. RESULTS: The study included 102 patients and 173 affected eyes. The mean age at presentation was 11.4 ± 3.7 years. Uveitis was predominantly bilateral (69.6%), anterior (45.1%), and chronic (58.8%). The leading diagnoses were idiopathic uveitis (38.2%), pars planitis (19.6%), and juvenile idiopathic arthritis-associated uveitis (14.7%). Infectious uveitis accounted for 12.7%, and toxoplasmosis was the most common cause (10.8%). At least one complication was observed in 76.3% of the eyes, and optic disk edema (37%) was the most frequent. Corticosteroids were used in 97.1% and systemic immunomodulatory agents in 49% of the patients. Ocular surgery was performed in 17.3% of the eyes, and cataract extraction was the most common (8.7%). The mean BCVA was 0.39 ± 0.66 LogMAR at baseline and 0.25 ± 0.53 LogMAR at the last recorded visit. CONCLUSION: Pediatric uveitis is a challenging disease that requires meticulous management. Anterior uveitis is the most frequent form. Despite a changing trend for an increase in diagnostic variety, idiopathic cases still constitute the majority. A significant number of patients receive systemic therapy, develop complications, and require surgical intervention. Early diagnosis and appropriate treatment might improve visual outcomes and reduce the risk of visual loss.

PURPOSE: To investigate both the possible effects of both idiopathic epiretinal membrane (IERM) itself and surgery on macular microvascular structure using optical coherence tomography angiography (OCT-A) and to determine the associations with structural and visual outcomes. METHODS: Twenty-four eyes of 24 patients with IERM and 24 eyes of 12 healthy controls were included. Vascular parameters, including the superficial capillary plexus (SCP) and deep capillary plexus (DCP) were evaluated by OCT-A prior to and 6 months after ERM removal. The foveal avascular zone (FAZ, mm2) area, parafoveal vascular density (VD, %) and flow area (mm2) measurements were used to evaluate the macular vascular integrity. RESULTS: The mean preoperative vascular density (VD) of both plexuses was lower in eyes with IERM than in healthy eyes (both p = 0.0001). The mean preoperative flow area of the DCP in eyes with IERM was significantly lower than that in the control eyes (p = 0.016). There was no significant difference in the VD or flow area in either superficial or deep capillary plexuses as a result of surgery (SCP; p = 0.957, p = 0.97, DCP; p = 0.861, p = 0.6, respectively). Both the parafoveal DCP-VD and flow area in DCP were negatively correlated with best-corrected visual acuity (logMAR) at 6 months postoperatively (r = -0.46, p = 0.03; r = -0.52, p = 0.01, respectively). CONCLUSION: Epiretinal membranes may cause dynamic microvascular changes at the macula. However, the effect of surgery on microvasculature may be more limited than that on anatomical and visual recovery. OCT-A may serve as a useful tool in understanding the pathophysiological basis of diseases.

To investigate the efficiency and safety of a single injection of intravitreal dexamethasone implant in eyes with persistent diffuse diabetic macular edema (DME). In this retrospective study, 25 eyes of 20 patients, who underwent a single injection of intravitreal dexamethasone implant for the treatment of persistent diffuse DME, were reviewed. Main outcome measures included the changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT) from baseline at scheduled visits following injection. The mean BCVA showed improvement from baseline (0.97 ± 0.26 logMAR) at every visit; the difference was significant at day 7 (0.85 ± 0.3 logMAR, p = 0.003), month 1 (0.77 ± 0.32 logMAR, p < 0.001), month 3 (0.77 ± 0.34 logMAR, p = 0.001), and month 4 (0.85 ± 0.31 logMAR, p = 0.014). The mean CMT was significantly lower than baseline (616 ± 132 µm) at day 1 (518 ± 144 µm), day 7 (414 ± 134 µm), month 1 (306 ± 95 µm), month 3 (339 ± 88 µm), month 4 (420 ± 116 µm), and month 6 (494 ± 128 µm) following the injection (p < 0.001, for all). Thirteen eyes on the 4-month follow-up and ten eyes on the 6-month follow-up experienced recurrence of macular edema requiring retreatment. No serious ocular and systemic adverse events were observed. In patients with persistent DME, switching to intravitreal dexamethasone implant injection provides functional and anatomical improvement, and might be an effective therapeutic option for long-standing diffuse DME.

PURPOSE: To investigate changes in choroidal thickness after intravitreal injection of a dexamethasone implant for macular edema due to retinal vein occlusion. METHODS: Thirty-one eyes of 31 patients, treated with a single dose of a dexamethasone implant for retinal vein occlusion-associated macular edema, were included. Subfoveal choroidal thickness (SFCT) and central macular thickness of the affected eyes were compared with those of the normal contralateral eyes at baseline and 1, 3, and 5 months after injection. RESULTS: The mean SFCT of the affected eyes (296.3 µm ± 61.6 µm) was significantly higher than that of the contralateral eyes (251.2 µm ± 57.7 µm; P < 0.001) at baseline. After injection, the mean SFCT was decreased compared with baseline in the treated eyes at months 1, 3, and 5. There was a correlation between SFCT and central macular thickness in the affected eyes at baseline (r = 0.397, P = 0.027). The change in SFCT was not correlated with the change in central macular thickness after injection. In the contralateral eyes, the mean SFCT did not change significantly. CONCLUSION: Subfoveal choroidal thickness in eyes with macular edema due to retinal vein occlusion was higher than that of the contralateral eyes. Intravitreal injection of a dexamethasone implant was associated with a reduction in the choroidal thickness of the treated eye.

OBJECTIVE: To evaluate the choroidal thickness in patients with multiple sclerosis (MS) using enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS: In this observational comparative study, 68 eyes of 34 MS patients and 60 eyes of 30 healthy subjects were evaluated. All participants underwent complete ophthalmologic examination and OCT scanning. Choroidal thickness measurements were performed at seven points. RESULTS: The mean subfoveal choroidal thickness was reduced significantly in MS patients (310.71 ± 61.85 µm) versus healthy controls (364.85 ± 41.81 µm) (p < 0.001). The difference was also significant at all six measurement points (p < 0.001 for all). Choroidal thickness measurements revealed no significant difference between MS eyes with a prior optic neuritis (ON) history (MS ON) and those without ON history (MS non-ON). Subfoveal choroidal thickness did not correlate with retinal nerve fiber layer and Expanded Disability Status Scale score, but reduced choroidal thickness was associated with longer disease duration (r = -0.28, p = 0.019) in MS patients. CONCLUSION: In MS patients, choroidal structural changes occur both in MS ON and MS non-ON eyes. The decreased choroidal thickness might provide evidence to support a potential role of vascular dysregulation in the pathophysiology of MS.

OBJECTIVE: Recent studies have shown close association between serum Immunoglobulin G4 (IgG4) levels and forms of autoimmune thyroiditis. However, there are limited data about the relationship between IgG4 and Graves' ophthalmopathy (GO). In the present study, we aimed to determine the possible association between IgG4 and GO. DESIGN: Cross-sectional study. PATIENTS: Sixty-five patients with Graves' disease (GD) and 25 healthy controls were recruited into the study. Thirty-two of these patients had GO. MEASUREMENTS: Serum IgG4 levels, thyroid functions and thyroid volumes were measured in all participants. Ophthalmological examination including Hertel's exophthalmometer readings (HER), Schirmer's test (ST), 'NO SPECS' classification and clinical activity score evaluation (CAS) were performed to all patients with GD. RESULTS: IgG4 levels were significantly elevated in patients with Graves' disease compared to controls (P = 0·0001). Also, IgG4 levels were significantly higher in patients with and without GO when compared to control subjects (P = 0·0001 and P = 0·002, respectively). Furthermore, IgG4 levels were significantly higher in the GO group compared with GD patients without GO (P = 0·024). IgG4 levels were observed to increase in parallel to CAS. Compared with other GD patients, 15 GD patients with serum IgG4 levels ≥ 135 mg/dl had higher CAS scores (P = 0·012). None of the factors including, TSH, T3, T4 levels, thyroid volume, HER and ST measurements, affect IgG4 levels as an independent factor. CONCLUSION: IgG4 levels are evidently increased in patients with GD, and there is a possible relationship between IgG4 and GO. Our results suggest that IgG4 may be helpful in screening GD patients with high risk for GO and may well become a good indicator for the selection of right medication in the future.

BACKGROUND AND OBJECTIVE: This study aimed to identify the prognostic factors regarding the visual and anatomic outcomes of eyes with posterior segment intraocular foreign body (PS-IOFB). PATIENTS AND METHODS: The medical records of 95 patients who underwent pars plana vitrectomy and PS-IOFB removal between 2004 and 2021 were retrospectively reviewed. Data on anatomical and visual outcomes, as well as preoperative, intraoperative, and postoperative variables were statistically analyzed. RESULTS: The mean age of the patients was 31.9 ± 12.3 years. The mean follow-up time was 21.9 ± 28.3 months. The median time interval from trauma to IOFB removal was 9 days. In univariate analysis, there was a positive correlation between initial visual acuity (VA) and final VA (P < 0.001). A higher ocular trauma score (OTS) was significantly associated with both anatomical and functional success (P < 0.001). Linear regression analysis showed that OTS was not superior to initial VA in predicting final VA (r = 0.625 vs r = -0.601). Anatomic and functional outcomes were not affected by the injury site, nature of PS-IOFB, or timing of PS-IOFB removal (P > 0.05 for all). Subretinal IOFB location, the need for silicone oil tamponade, and endophthalmitis (P = 0.005, P < 0.001, P = 0.044, respectively) were risk factors for poor visual outcome. CONCLUSIONS: The initial VA, the extent of the initial ocular damage, and the presence of endophthalmitis are important prognostic factors for functional success.

To report the role of early vitrectomy and silicone oil tamponade in acute endophthalmitis following intravitreal injection. Medical records of eight patients who presented with acute endophthalmitis after intravitreal injection of different drugs were retrospectively reviewed. Initial treatment consisted of vitreous tap with cultures and injection of intravitreal antibiotics, with the patients subsequently undergoing pars plana vitrectomy and silicone oil tamponade within 24 h following initial vitreous tap. The mean time to presentation was 1.7 days (1-3 days). The initial best-corrected visual acuity was hand motion to 0.05 before treatment and 0.05-0.8 (Snellen) after treatment. Vitreous cultures were obtained from all patients, of which four were culture positive. Endophthalmitis was controlled in all patients. There was no retinal detachment or phthisis bulbi during the follow-up period (1-4 years). Acute endophthalmitis following intravitreal injection occurs rapidly and requires urgent treatment. If intravitreal antibiotics fail to control inflammation, early pars plana vitrectomy and silicone oil tamponade would be an appropriate option.

PURPOSE: To evaluate the retinal and choroidal microvascular blood flow in patients with human immunodeficiency virus (HIV) infection using optical coherence tomography angiography (OCTA). METHODS: Macular OCTA parameters including vessel density (VD) of parafoveal superficial capillary plexus (SCP-VD) and deep capillary plexus (DCP-VD), foveal vessel density (FD), foveal avascular zone area, and flow area of choriocapillaris were analyzed in 42 HIV-positive patients, and compared with 42 healthy controls. RESULTS: The mean SCP-VD, DCP-VD and FD were significantly lower in HIV-positive group compared with controls (p < .001, p = .014, p = .026; respectively). Reduced SCP-VD was associated with higher HIV RNA plasma level (r = -0.400, p = .021) and lower CD4 + T cell count (r = 0.314, p = .046) in HIV-positive patients. CONCLUSIONS: Macular microvascular blood flow is affected by HIV infection. OCTA can detect microvascular flow abnormalities in retinal capillary plexus in HIV-positive patients.

Clinical relevance: Pivotal studies are based on strict treatment regimens of vascular endothelial growth factor blocking drugs in neovascular age-related macular degeneration. However, looser regimens with poorer results have been reported in real-world studies with various outcomes. This results in a search of more precise data to rely on in the management of patients with neovascular age-related macular degeneration.Background: The aim of this study is to analyse the real-world outcome of vascular endothelial growth factor blocking agents in neovascular age-related macular degeneration.Methods: This is a retrospective comparative study of treatment-naïve patients who received intravitreal aflibercept or ranibizumab administration for neovascular age-related macular degeneration for at least 12 months on an as needed regimen following a loading phase of three-monthly injections. Full eye examination and optical coherence tomography scans were provided at all visits. The drugs were compared on the basis of visual acuity, central macular thickness, and subfoveal choroidal thickness. The baseline optical coherence tomography features were analysed seeking a correlation with the outcome.Results: One hundred and forty-one eyes were enrolled. The mean age was 71.7 ± 8.5 years. Sixty-eight (48.2%) patients received aflibercept and 73 (51.8%) received ranibizumab injections. The mean number of injections was 6.5 ± 2.5. The mean number of injections were also similar between groups (6.4 ± 2.5 vs. 6.5 ± 2.6, respectively, p = 0.783). At one year, both drugs caused significant increase in visual acuity and decrease in central macular thickness and subfoveal choroidal thickness.Conclusion: In a real-world setting, aflibercept and ranibizumab yielded similar results at one year in the management of neovascular age-related macular degeneration.

To evaluate the corneal findings in hydrogel contact lens wearers by in vivo confocal scanning microscopy. One hundred and forty-two eyes of 71 myopic contact lens wearers (group 1) and 142 eyes of 71 non-contact lens wearers (group 2), whose age, gender and refractive error matched, were enrolled in order to detect the corneal changes by in vivo confocal microscopy through the central cornea. The average age was 25.5 ± 5.7 (16-52) and 25.6 ± 5.6 (17-49) in groups 1 and 2, respectively. The mean duration of contact lens wear was 43.9 ± 15.3 (6-240) months. Anterior keratocyte density was 667.5 ± 128.3 cells/mm(2) in group 1 and 821.4 ± 136.7 cells/mm(2) in group 2 (P = 0.001). Posterior keratocyte densities of groups 1 and 2 were 540.2 ± 87.6 cells/mm(2) and 628.2 ± 72.4 cells/mm(2), respectively (P < 0.001). Endothelial cellular density was 2611.2 ± 298.4 cells/mm(2) in group 1 and 2643 ± 218.2 cells/mm(2) in group 2 (P = 0.52). Ratio of polymegethism was 44.6 ± 8.8% in group 1 and 31.3 ± 4.7% in group 2 (P < 0.001). Epithelial cellular enlargement was observed in eyes wearing contact lenses with a mean Dk/t ratio of 26.5 × 10(-9) ± 5.9 (8.9-32 × 10(-9)). Stromal microdots occurred with contact lenses with a mean Dk/t ratio of 13.2 × 10(-9) ± 17.5 × 10(-9) (8.9-20 × 10(-9)). In vivo examination of the cornea with confocal microscopy revealed a number of changes. These changes can be attributed both to the mechanical and the hypoxic effects of soft contact lenses. In soft contact lenses with a high Dk/t ratio, these changes would be less frequent.

BACKGROUND: To evaluate the retinal and choroidal microstructural changes at fovea after half-dose photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (CSC), using optical coherence tomography (OCT). METHODS: The study included 35 eyes with unilateral chronic CSC treated with half-dose PDT. The foveal outer nuclear layer (ONL) and subfoveal choroidal thickness (SFCT) in the affected eyes were compared with baseline measurements at month 1, 3, and 6 after half-dose PDT, and those of the healthy contralateral eyes. RESULTS: The mean baseline ONL thickness of the affected eyes was thinner compared to unaffected fellow eyes (66.9 ± 16.5 µm vs 111.5 ± 11.6 µm, p<0.001), and increased significantly to 68.6 ± 17.0 µm at month 3 and 68.9 ± 17.3 µm at month 6 after treatment (p = 0.025 and p = 0.014 respectively). The mean baseline SFCT of the affected eyes was thicker compared to unaffected fellow eyes (399.9 ± 87.0 µm vs 338.2 ± 75.4 µm, p<0.001), and decreased significantly after treatment at month 1, 3, and 6 (374.0 ± 84.8 µm, 369.7 ± 81.8 µm, 367.3 ± 80.8 µm respectively, p<0.001 for all). The responder group (n = 26), in which subretinal fluid was completely resorbed, showed a significant increase in ONL thickness and decrease in SFCT after treatment, whereas in the non-responder group (n = 9) ONL thickness and SFCT did not differ after treatment. CONCLUSIONS: In CSC patients, significant changes are observed in foveal ONL thickness and SFCT after half-dose PDT. ONL thickness and SFCT are suggested to be considered in the OCT examinations of CSC patients.

Clinical relevance: Retinopathy of prematurity is a preventable blinding disorder worldwide. Laser photocoagulation is said to be the gold standard care of treatment. However, various factors are known to affect the outcome.Background: The purpose of this study was to analyse the risk factors in patients with laser treatment requiring retinopathy of prematurity (ROP) and the outcome of 532 nm Nd:YAG laser photocoagulation (LP).Methods: Patients who underwent LP for ROP at a tertiary referral centre between January 2012 and January 2019 were enrolled. Those who were born and followed-up at the institution of the authors were in Group 1 and those who were born and followed-up elsewhere and referred to the authors for treatment were in Group 2. The clinical features, gestational ages, birth weights, and data regarding the treatment were retrospectively reviewed. The need for pars plana vitrectomy was taken as a poor outcome.Results: The mean gestational age and birth rate was 26.7 ± 1.9 weeks and 927.2 ± 263.5 grams, respectively, in Group 1 (57 infants, 111 eyes); and 28.5 ± 2.5 weeks and 1174.8 ± 385 grams, respectively, in Group 2 (66 infants, 131eyes) (p < 0.001 for both). The extent of the disease (p < 0.001), the zone of the disease (p = 0.002), and the timing of LP (p < 0.001) were significantly different between groups. In the whole cohort, the zone (p = 0.006) and stage (p < 0.001) of the disease, aggressive posterior disease (p = 0,009), and tunica vasculosa lentis were found to significantly interfere with the outcome.Conclusion: Eyes with more severe disease undergoing timely treatment and eyes with less severe disease undergoing delayed management had similar prognosis. A favourable outcome was obtained with 532 nm green laser in ROP.

PURPOSE: To investigate the histopathological results of lacrimal sac biopsies in patients with primary acquired nasolacrimal duct obstruction. METHODS: In this prospective non-comparative study, 205 consecutive patients, who were diagnosed as primary acquired nasolacrimal duct obstruction, were included. Patients with history of trauma and/ or surgery in the periorbital area, punctum or canalicular obstruction were excluded from the study. Patients were evaluated for age, gender, history, and presenting symptoms. Lacrimal drainage system abnormalities were assessed. Lacrimal system irrigation, dacryocystography, and in selected cases dacryoscintigraphy was performed. All patients underwent external dacryocystorhinostomy. Biopsy specimens were obtained from the posterior inferior flap and examined by the same pathologist. RESULTS: Forty-seven male and 158 females with age ranging from 6 to 81 years (mean 47.5 ± 16.2 years) were included in the study. Only one patient had the diagnosis of chronic leukemia, others had no preexisting history of systemic disease. Pathologic examination revealed chronic inflammation (n= 178), fibrosis without inflammation (n= 19), normal mucosa (n= 4), and lymphoid hyperplasia (n= 1). Three patients had abnormal pathology: Lymphoproliferative disease in the patient with chronic leukemia, granulomatous inflammation, and basosquamous cell carcinoma. CONCLUSION: In primary nasolacrimal duct obstruction, pathological examination of the lacrimal sac revealed chronic inflammatory changes in most patients. Even though rare, malignant or systemic disease in patients with neither specific history nor clinical or radiological finding might be observed in these cases. Thus, we recommend taking biopsy if any suspicion of abnormality of the lacrimal sac exists.

PURPOSE: To evaluate the epidemiology and outcome of ocular trauma in southern Turkey. METHODS: Patients referred to the University of Cukurova, School of Medicine, Department of Ophthalmology, with ocular trauma during the last two years were reviewed retrospectively. Age and gender of patients, type of injury, cause of injury, place where injury occurred, initial and final visual acuities, and final outcome were analyzed. RESULTS: Medical records of 250 patients (four bilateral injuries), aged between three months and ninety years were reviewed. Ocular trauma mostly occurred between 0 and 15 years and a male preponderance (76.8%) was evident. There were 72% open-globe injuries, corneal and/or scleral penetration being the most common injury type. Metallic objects were the main cause of injury (32.4%). Fifty percent of injuries happened in streets. Closed-globe and self-sealing corneal injuries were found to have the best prognosis in terms of final outcome (57.6% and 57.9%, respectively; P < 0.001 for both). Initial visual acuity was found to be a significant predictor of final visual acuity (P < 0.001). Endophthalmitis was significantly associated with metallic objects (P < 0.005). CONCLUSION: Eye injury is still a common and avoidable cause of blindness. Our findings suggest that any person in the population can be subject to ocular trauma at any time. Prognosis might be challenging. Education, attention, and safety precautions would help in reducing ocular morbidity.

OBJECTIVES: Behcet Disease (BD) is a systemic vasculitis, first described with a triad of oral aphthous ulcers, genital ulcers, and uveitis. The authors aimed to share the clinical properties and utilities of three distinct classification criteria for BD in this study. METHODS: This case-control study was conducted in pediatric BD patients, diagnosed between January 2012 and July 2019. The control group included 53 children with other rheumatic disorders. Sensitivity and specificity for International Study Group (ISG), International Criteria for BD (ICBD), and pediatric criteria for BD (PEDBD) criteria were tested. RESULTS: The mean age at symptom onset and diagnosis of the 16 BD patients (6 females, 10 males) were 11.2 ± 3.6 and 13 ± 3.1 years, respectively. The sensitivity and specificity of ISG criteria were 87.5% and 100%. Furthermore, ICBD criteria had a sensitivity and specificity of 93.7% and 98.1%, whereas the authors found sensitivity and specificity as 93.7% and 96.2% for PEDBD. CONCLUSION: ICBD and PEDBD reached higher sensitivity for pediatric BD diagnosis and ICBD had the highest specificity. The authors speculate that the utilization of ICBD may provide early diagnosis of BD in childhood, prevent related morbidities and misdiagnosis.
