OBJECTIVES: It was aimed to to provide a comprehensive assessment of therapeutic and tectonic emergency keratoplasty procedures, along with a discussion on their indications, prognostic factors for functional success, and postoperative outcomes.
METHODS: Patients who underwent therapeutic or tectonic Penetrating Keratoplasty (PKP) procedures between 2010 to 2021 in our hospital were retrospectively reviewed. Patient files were evaluated in terms of demographic characteristics, medical and ocular history, visual acuity, initial ocular findings, presence of glaucoma, causative microorganisms, details of surgical procedures, complications, graft transparency and globe integrity. Visual acuity was measured as light perception, hand motion, counting finger, Snellen chart and subsequently converted to Logarithm of the Minimum Angle of Resolution (logMAR) for statistical analysis.
RESULTS: The study included a total of 43 patients, with 16 (37.2%) being female. The average age of the participants was 59.72±18.1 years. The corrected distance visual acuity improved from 2.3±0.66 logMAR preoperatively to 1.72±1.02 logMAR postoperatively (p=0.001). After PKP, anatomical success was achieved in all eyes and functional success was achieved in 23 (51.1%) eyes. It was observed that only preoperative glaucoma had a significant impact on graft survival rate (p=0.002, Figure 2), as well as functional success (p=0.022).
DISCUSSION AND CONCLUSION: Urgent keratoplasty is a viable treatment option for cases involving an actively uncontrolled infection or corneal disease with perforation. In cases of graft rejection, bacteria, fungi, and viral pathogens were detected as causative agents, whereas only bacteria were detected as the causative agents in cases of pre and post-operative endophthalmitis. Early diagnosis and treatment play crucial roles in achieving anatomical and functional success.

OBJECTIVES: The objective of this study was to analyze the changes in the effective optical zones (EOZ) using topographic techniques on the tangential curvature difference map at post-operative 1-year following transepithelial photorefractive keratectomy (T-PRK) and to identify parameters linked to the EOZ alterations.
METHODS: The study comprised 55 eyes of 55 myopic patients who underwent T-PRK. EOZs were measured using the tangential curvature difference map of the Scheimpflug tomography system. Correlations between the EOZ alterations and relevant parameters were assessed.
RESULTS: The EOZ was significantly lower than the programmed optical zone (p<0.001). The decrease in the EOZ was significantly relevant to the decrease in mean keratometry (p=0.01, B/95% confidence interval [CI]: 0.139/0.033 and 0.244, standardized Beta: 0.346) and the increase in maximum keratometry (p=0.003, B/95% CI: 0.072/0.026 and 0.118, standardized Beta: 0.406).
DISCUSSION AND CONCLUSION: The EOZ decreased in the 1st year after T-PRK in eyes with myopia. The decrease in the EOZ was corre-lated positively with the decrease in mean and maximum keratometry. T-PRK may be an effective and safe surgery for the correction of mild-to-moderate myopia.

OBJECTIVES: The aim of this study was to compare the outcomes of Ahmed glaucoma valve implantation (AGVI) in neo-vascular glaucoma (NVG) due to proliferative diabetic retinopathy (PDR) with or without a pars plana vitrectomy (PPV) history and to analyze the factors affecting surgical failure.
METHODS: Patients with NVG secondary to PDR undergoing AGVI at a single center were reviewed retrospectively. The surgical failure rates and post-operative complications were compared between eyes with (PPV-AGVI group) and without previous PPV (AGVI group). Failure was defined as loss of light perception or intraocular pressure (IOP) >17 mmHg despite maximum medication, or need of additional intervention for IOP control or for the management of complications. Survival analysis was investigated by Kaplan–Meier test. The possible factors for failure were analyzed with logistic regression analysis.
RESULTS: The failure rates were 21.9% during the mean follow-up of 27.56±15.38 months and 14.3% during 23.63±12.38 months, in PPV-AGVI group (n=32) and in AGVI group (n=49), respectively (p=0.37). The frequency of complications and surgical intervention need for management of post-operative complications was similar between groups (p>0.05). There was no significant difference in survival analysis (p=0.13). The history of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection before AGVI was significantly associated with failure (odds ratio = 26.941, p=0.02).
DISCUSSION AND CONCLUSION: The results of AGVI performed with long scleral tunnel technique were comparable in terms of failure rates, between NVG patients with and without previous diabetic vitrectomy. The only significant factor for failure was intravitreal anti-VEGF pre-treatment. This may be related to the necessity of anti-VEGF therapy in aggressive PDR, and also, anti-VEGF agents may increase fibrosis in the anterior chamber angle.

OBJECTIVES: The objective of this study was to compare anxiety, depression, self-esteem, and quality of life in patients who underwent surgical removal of an eye with those of controls as well as to test the correlations of these variables in both groups.
METHODS: Beck anxiety inventory (BAI), Beck depression inventory (BDI), 36-item short-form health survey (SF-36), and Rosenberg self-esteem scale were administered to 29 patients with surgical removal of an eye and 30 control subjects.
RESULTS: The patient group had significantly lower scores on physical functioning, role limitations due to physical and emotional problems, pain, and general health perception domains of SF-36, as well as significantly higher BDI (p=0.004) scores as compared to controls. The study groups did not differ significantly with respect to BAI scores and energy/vitality, mental health, and social functioning domain scores of SF-36 (p>0.05).
DISCUSSION AND CONCLUSION: This population of monocular patients had similar mental health-related and Beck’s Anxiety Inventory scores equivalent to the control group despite the surgical removal of one eye. However, lower scores for some SF-36 domains and higher depression levels in this patient group suggest that psychiatric rehabilitation should be considered after eye removal to improve the psychological outcomes and quality of life in these patients.

OBJECTIVES: This study aimed to evaluate serum biomarker values measured during second-trimester aneuploidy screening in terms of their predictive ability for the development of retinopathy of prematurity (ROP) in premature infants.
METHODS: This retrospective cohort study evaluated the data of 1985 idiopathic premature infants who underwent ROP screening from 2016 to 2022. The infants were divided into two groups according to the presence of ROP, and those with ROP were further evaluated in two subgroups based on the presence of proliferation. Comparisons were made concern-ing the serum multiple of the median values of unconjugated estriol (uE3), human chorionic gonadotropin (hCG), and alpha-fetoprotein (AFP) among aneuploidy screening biomarkers.
RESULTS: While 1628 premature infants were in the non-ROP group, 357 were in the ROP group. Of the infants with ROP, 72 were in the proliferative ROP group and 285 in the non-proliferative ROP group. There was no significant difference in the multiple of the median values of the evaluated serum biomarkers (uE3, hCG, and AFP) between the ROP and non-ROP groups or between the proliferative ROP, non-proliferative ROP, and non-ROP groups.
DISCUSSION AND CONCLUSION: The multiple of the median values of second-trimester aneuploidy screening serum biomarkers were not able to predict the development of ROP in premature infants. This result may have been caused by the fact that the blood tests were taken only once and in the same weeks.

OBJECTIVES: The focus of this study was to assess and compare the h-indexes of editorial board members from eight ophthalmology journals in Türkiye and explore the potential correlations between these indexes and the sub-specialties of board members.
METHODS: Conducted in December 2023, this cross-sectional study utilized publicly available data from Google Scholar (GS), Web of Science, and Scopus. The h-index and number of publications by editorial board members from eight Turkish ophthalmology journals were analyzed. Statistical analysis for this study involved the use of SPSS, employing descriptive statistics, one-way analysis of variance, and post hoc tests for group comparisons.
RESULTS: Of the 415 editorial board members, 26 were not ophthalmologists and 12 worked abroad; the credentials of 10 could not be verified. A total of 367 authors were evaluated, revealing significant differences in publication numbers and h-indices among the different subspecialties. Notably, the retinal specialists demonstrated higher productivity. Variability in citation counts was observed across databases, with GS having the widest range. Differences were also noted in the publication and h-index among the editorial boards of different journals.
DISCUSSION AND CONCLUSION: The h-index and number of publications effectively reflected the active status of ophthalmology authors. This study contributes valuable information regarding Turkish ophthalmology journals and their editorial boards, serving as an inspiration for young ophthalmologists. These findings underscore the diverse successes of ophthalmologists across subspecialties, encouraging the exploration of less-explored areas in academic pursuits.

We describe the case of a 37-year-old male who experienced an isolated rupture of the inferior rectus muscle in the right eye following a facial impact from a wire. Upon examination, a minor restriction in downward gaze was observed. An orbital computed tomography scan confirmed the integrity of the globe and the absence of an orbital fracture—subse-quent surgical exploration involved identifying and suturing together the distal and proximal ends of the affected muscle. Postoperatively, normal eye movements were restored.

Optic aphasia is a rare neurological disorder that affects the visual-semantic ability of patients with normal vision and is caused by a lesion in the left occipital lobe. The signs and symptoms of optic aphasia are similar to those of associative visual agnosia, where patients have difficulty recognizing objects both in shape and function, resulting in challenges per-forming daily tasks. The transformation to optic aphasia or associative visual agnosia is closely related to the degree of damage to the corpus callosum, with some studies hypothetically suggesting that complete damage to the corpus callosum leads to optic aphasia, whereas incomplete damage causes associative visual agnosia. We present a case of a 60-year-old man with a history of intracerebral hemorrhage in the left occipitotemporoparietal lobe. The patient complained of intermittent episodes of painless, blurry vision. Upon examination, we observed that the patient was unable to read the Snellen chart, although he could draw the letter. Furthermore, we discovered that the patient had difficulty naming objects and instruments, even though he was able to express their shape and function through gestures and mimicry. The signs and symptoms of the patient, along with the result of the multi-slice non-contrast CT scan, suggest that he had optic aphasia rather than associative visual agnosia. A comprehensive neuropsychological and aphasia examination needs to be performed to further assess the condition of our patient and establish the diagnosis.
